5      ==============================      ==============================
6    
7  checkpoint52j_post  o pkg/salt_plume: added diagnotic for salt tendency (oceSPtnd).
8    o AD_CONFIG.h file:
9     - in genmake2: remove "#undef ALLOW_ECCO_OPTIMIZATION" from AD_CONFIG.h;
10     - remove #include "AD_CONFIG.h" from all included OPTIONS files and
11       add it explicitly in each fortran src file where it is needed.
12       motivation: header file AD_CONFIG.h is generated/modified after "make depend"
13       thus introducing potentially wrong dependency; therefore, better to include
14       it only where it's really needed, and after any other included OPTIONS file
15       (less tempting to bring conditional includes according to ALLOW_ADJOINT_RUN
16       or ALLOW_TANGENTLINEAR_RUN).
17    
18    checkpoint63p (2012/07/06)
19    o pkg/autodiff:
20      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
21      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
22        which are now read from new parameter file "data.autodiff" (inAdExact
23        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
24      - add file "data.autodiff" in all verification/*/input_ad/ directories.
25      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
26        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
27    o verification/tutorial_tracer_adjsens/
28      - add extra sub-verification which uses "SOM" advection scheme
29        (2nd Order-Moment Advection Scheme, Prather Limiter) with
30          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
31        and in data:
32          multiDimAdvection=.TRUE.,
33          tempAdvScheme=81,
34          saltAdvScheme=81,
35    o model/src:
36      - introduce ALLOW_BALANCE_RELAX which allow the removal
37       of the global mean of relaxation terms by setting
38       balanceThetaClimRelax and balanceSaltClimRelax
39      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
40       This case is now treated appropriately in seaice_growth.F
41    o pkg/seaice:
42      - do balanceEmPmR and balanceQnet based on the net fluxes
43        (SItflux) that enter the ocean+ice system rather than QNET
44        and EMPMR. Works best in real fresh water.
45      - SIatmFW, SIatmQnet, and SItflux computations had to be moved
46        out of the diagnotics bloc, and stored in global arrays.
47    
48    checkpoint63o (2012/06/29)
49    o vertical mixing schemes:
50      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
51      - replace computation of density (in Function STATE1, opps_calc.F) by a call
52        to S/R FIND_RHO_SCALAR
53      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
54        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
55        affects output (vermix.ggl90) at truncation level.
56    o testreport:
57      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
58        (nSx,nSy) for the number of threads (from eedata.mth)
59    o model/src:
60      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
61        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
62    o verification/tutorial_tracer_adjsens/
63      - compile with ALLOW_CG2D_NSA
64      - run with nonlinFreeSurf=3
65      - update reference output_adm.txt
66    o tools/genmake2:
67      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
68        refine usePROFILES switching off (only when NetCDF is not available).
69    o verification (atmospheric set-up):
70      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
71    o pkg/profiles : refine profiles and files handling.
72    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
73    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
74      - changes to use model/src/the_main_loop.F rather than the ecco version
75        in ecco type adjoint runs.
76    o model/src:
77      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
78      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
79      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
80    o model/src:
81      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
82        update output of test experiment bottom_ctrl_5x5.
83    o pkg/generic_advdiff:
84      - implement vertical bi-harmonic diffusion (for now, only for T & S and
85        only explicitly).
86    o verification/bottom_ctrl_5x5/
87      update reference output (results changed quite some time ago,
88      not sure when; but new reference results look ok in terms of grdchk)
89    o verification/1D_ocean_ice_column/
90      For verification purposes, the exact adjoint rather than an approx.
91      should be used (e.g., to comare against F.D. or TLM).
92      removed autodiff_inadmode*_ad.F routines in code_ad/
93      Update results/ accordingly.
94    o pkg/cal:
95      - change cal_getdate.F so that output date is function of input time only
96        (less ambiguous, not mixed up with input iteration number).
97      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
98    o pkg/diagnostics:
99      - implement calendarDumps also for stats-diags
100      - implement calendarDumps also for snap-shot output (negative freq)
101      - for now, ignores calendarDumps if non-zero phase-lag.
102    
103    checkpoint63n (2012/06/04)
104    o model/src:
105      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
106        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
107      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
108        similar to calc_r_star.F); update results of experiment internal_wave and
109        tutorial_global_oce_in_p (affected @ truncation level).
110    o pkg/shelfice:
111      - add parameterisation of advective-diffusive flux into the ice shelf
112        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
113      - simply eps3/3a computation
114    o eesupp:
115     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
116       between tiles, just fill-in edges assuming locally periodic subdomain) and
117       add corresponding exchange subroutines (EXCH0);
118     - new CG-solver version (_EX0) for disconnected-tiles special case.
119    o model/src (CG-solvers):
120     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
121       (similar final residual output and max-Iter number as with standard version);
122     - allows to store and use lowest-residual solution (standard & _SR versions);
123     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
124     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
125    o eesup/src:
126     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
127       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
128    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
129    
130    checkpoint63m (2012/04/27)
131    o pkg/shelfice:
132     - account for partical cells in surface level below ice-shelf for hydrostatic
133       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
134    o ad test experiments:
135     - update and rename to "ad_optfile.local" local AD-optfile specific to a
136       particular adjoint verification experiment (in verification/*/code_ad/)
137    o pkg/seaice & pkg/exf:
138     - Part two of ECCO-CLIVAR code merges.
139       Completes merge of seaice area relax. code.
140       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
141       to be set in EXF_OPTIONS.h since this pkg controls its I/O
142       (and avoids second CPP option in SEAICE_OPTIONS.h)
143     - change default value of costIceStart & costIceEnd to a valid date.
144     - add snowPrecip to HSNOW in seaice_growth
145    o pkg/ptracers:
146     - move ptracers summary and setup check into separated S/R ; add a check for
147       valid PTRACERS_Iter0 value (error+stop or just warning).
148    o pkg/cal (+ pkg/ecco):
149     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
150       as input; and for AD, unless both are not differentiable (e.g., k index)).
151    o model/src:
152     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
153       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
154       temporary set to usingZCoords value (to be changed to F when using shelfice).
155     - hydrostatic pressure: implement partial cell near the surface also for
156       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
157       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
158    o pkg/ctrl/ctrl_init.F:
159     - add a formal parameter to s/r ctrl_init_rec to print
160       xx_$(ctrl_valiable)_file for easier debugging
161     - move call of cal_* routines into the if-block where they are really
162       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
163       to specify a startdate
164    o pkg/seaice:
165     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
166       global_ocean.cs32x15/code versions).
167     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
168       verification experiment global_ocean.cs32x15.seaice and update results.
169    o pkg/exf:
170     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
171       (according to useExfYearlyFields).
172    o pkg/cal:
173     - move calendar setting & summary (previously in cal_readparams.F) into new
174       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
175       length of the simulation is set (after SET_PARMS call); This is an attempt
176       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
177     - For safety: keep a record of pkg/cal parameter settings status
178               to allow to STOP if one pkg/cal S/R is called too early.
179     - add a stop in all basic pkg/cal subroutines if called before setting is done.
180     - modify cal_getdate.F: stop when nothing was returned;
181       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
182       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
183    
184    checkpoint63l (2012/04/04)
185    o pkg/bbl:
186      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
187        update global_with_exf output.yearly.txt file.
188    o pkg/cal:
189      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
190      - remove 2 unsused and very short (1 line only) functions ;
191      - remove unsused subroutines from AD-Diff list.
192    o model/src:
193      - start to implement clean wait to stop in initialization S/R (config_check.F,
194         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
195    o folowing PRINT_MESSAGE changes:
196      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
197    o pkg/bbl:
198      - modification so it can work with z*
199      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
200      - global_with_exf/input.yearly verification; changes output.yearly.txt
201    o eesupp/src:
202      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
203        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
204      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
205        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
206      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
207      - when using MPI, always set usingMPI=T ; set default accordingly and stop
208        if not consistent.
209      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
210        argument is zero (in case called within single-thread section).
211    o pkg/fizhi:
212        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
213        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
214    o pkg/exch2:
215      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
216        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
217      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
218        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
219        with bad ones coming from a not-yet-updated halo.
220        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
221    o pkg/frazil:
222        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
223        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
224    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
225    o verification/lab_sea
226      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
227      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
228      * nTimeSteps 3 -> 4
229      * changed reference output accordingly
230    o pkg/ctrl:
231      * fix ctrl_get_gen for xx_sst, xx_sss
232    o pkg/fizhi:
233      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
234        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
235      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
236        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
237        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
238    o pkg/gmredi:
239      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
240    o pkg/fizhi:
241      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
242        (old)aces open64 tuv test.
243    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
244    o pkg/mom_vecinv:
245      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
246        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
247        with non-lin free-surf).
248    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
249      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
250      some compilers (gfortran 4.6.0 on MacOS)
251    o momentum:
252      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
253        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
254        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
255    
256    checkpoint63k (2012/03/17)
257    o model/src:
258       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
259         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
260       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
261         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
262    o model/src: solve_*diagonal.F
263       - replace division with multiplication by inverse (similar to original version)
264         update output of AD exp. global_ocean.90x40x15.
265       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
266         to enable the use of the vectorized & differentiable solve_tridiagonal.F
267       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
268         vertical advection (to get solve_tridiagonal tested in AD mode).
269    o pkg/seaice: ECCO-CLIVAR merge:
270      1. seaice AREA relaxation
271         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
272         * runtime flag: SEAICE_tauAreaObsRelax
273      2. modified global mean cost imbalance code: CPP option
274          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
275    o another iteration on solve_*diagonal.F
276       Make choices independent of AUTODIFF
277       Default will be the adjoinable vectorized version.
278       Alternative choices are:
279       * non-adjoinable original version with low memory footprint:
280         #define SOLVE_DIAGONAL_LOWMEMORY
281       * still adjoinable but does not vectorize (k as inner-most loop):
282         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
283    o testreport
284     - add option to use a home made wrapper around "make"
285     - remove MITGCM_IEEE env. variable (no longer active)
286    o pkg/shelfice
287     - improve computation of friction velocity for velocity dependent
288       exchange coefficients: include velocities into SHELFICEBoundaryLayer
289       block to average velocities vertically
290     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
291    o Modify diagonal solvers, now three versions (upon request):
292      #ifndef SOLVE_DIAGONAL_AUTODIFF
293        1. default version (dating back a while ago)
294      #else /* def SOLVE_DIAGONAL_AUTODIFF */
295      # ifdef SOLVE_DIAGONAL_KINNER
296        2. adjoinable version with k-innermost loop (G. Forget)
297      # else
298        3. adjoinable vectorized version of 2.
299      # endif
300      #endif /* SOLVE_DIAGONAL_AUTODIFF */
301      All flags are currently set within routines, but could/should be moved to CPP-options.
302      Array bounds for 1. are as before, for 2.,3. cover the entire domain
303      (could be changed for 1. too).
304    o verification/lab_sea (fwd):
305      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
306        use 7 categories (except hb87), new solve4temp params (except salt_plume),
307        constant salinity (=4) or variable salinity (salt_plume) done through
308        SItracer.
309    o pkg/seaice:
310      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
311      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
312         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
313        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
314        SEAICE_freeze got retired) but already better than previously with
315        SEAICE_freeze=123456.7 deg.C;
316      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
317        (safer multi-threaded setting); always set SEAICEuseEVP;
318      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
319        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
320        stop if multiple specifications for the same coeff; make sure default
321        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
322    o pkg/obcs:
323      - allow to switch to upwind 1rst order advection scheme for the advective
324        flux computation at the open-boundary; disabled for adjoint built.
325    o pkg/ptracers:
326      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
327      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
328      - add parameter to decide when to start a tracer; use internal flag to
329        know which tracer to step-forward; switch this internal flag at the top
330        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
331        for adjoint built.
332    o pkg/seaice:
333      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
334      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
335      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
336    o pkg/ecco:
337      - fix writing of output file DiagnosCost_ClimSalt/Theta
338        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
339    o pkg/seaice:
340      - add missing initialisation of COR_ICE array in dynsolver.F
341      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
342        compiled either way, and is tested in all exps (multidim was only tested
343        in lab_sea ad before).
344      - cosmetic change to prepare for future addition of ITD. no change to results.
345        no defaults change.
346      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
347      - by lack of adequate verification experiments, I further used custom versions
348        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
349        should be correct.
350      - avoid recomputations in ad.
351    o array initialisation in adjoint mode:
352      1) pkg/mom_common/mom_calc_ke.F:
353        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
354        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
355        part this initialisation is gone, resulting in Floating Point Exception
356        (caught by open64 compiler with debug option).
357      2) model/src/convective_weights.F
358        set output convectCount over the full array range (instead of doing
359        an update): this fix a similar issue when called within recomputation (adjoint)
360        which could by-pass the initialisation (normally done in the caller S/R).
361    o pkg/seaice:
362      - final version of turbulent flux params, as agreed at MIT ice meet:
363           SEAICE_mcPheePiston (default is ~ 0.000875)
364           SEAICE_mcPheeTaper (default is 0.)
365           SEAICE_frazilFrac (defualt is 1.)
366           SEAICE_mcPheeStepFunc (default is false)
367      - changes results at trunction error level
368      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
369    o added pkg/frazil:
370      - see frazil_description.tex for details
371      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
372    o pkg/shelfice/shelfice_thermodynamics.F
373      - fix exponents for velocity dependent exchange coefficients: change
374        from 2/3(=0) to 0.66666666666666667
375      - move computation of velocity dependent exchange coefficients into
376        separate loop, so that it applies to both thermodynamics
377      - move some divisions by constants out of loops
378    
379    checkpoint63j (2012/02/16)
380    o pkg/seaice:
381      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
382      - SItracer:  added run time params, and allow coupling to ocn salinity.
383    o pkg/seaice: remove (almost) all divisions by constants within loops
384      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
385      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
386      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
387      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
388    o pkg/seaice :
389      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
390        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
391      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
392      - add permanent SItflux diag that corresponds to TFLUX but includes
393        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
394      - allow activation/testing of a fix for suspected missing term in
395        ocn-ice heat budget (to be confirmed). To test this, you want to
396        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
397        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
398      - no change in results, fwd or ad.
399    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
400      - switch to variable freezing point.
401           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
402      - bug fix : the sublimation term that was missing is now activated.
403           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
404      - bug fix : flooding sign term for SIsal0.NE.0.
405           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
406    o pkg/seaice:
407      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
408        is now the default, and the old default constant freezing point is recovered
409        with SEAICE_tempFrz0    = -1.96,
410             SEAICE_dTempFrz_dS = 0.,
411      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
412      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
413      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
414        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
415      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
416        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
417      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
418        seaice_growth r149 for legacy branch (no results change).
419      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
420        from I. Fenty).
421      - results did not change except for global_ocean.cs32x15, mostly due to the
422        switch to variable freezing point (see above item for detail).
423    o pkg/thsice:
424      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
425        seawater freezing in thsice_calc_thickn (not used).
426    o pkg/seaice: turbulent flux term specification via run time params.
427      - replace CPP switches with run time switches to facilitate testing
428      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
429                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
430      - added runtime parameter : SEAICEturbFluxFormula
431      - move Mcphee constants to SEAICE_PARAMS.h
432      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
433                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
434                 remove seaice_summary call (moved to seaice_init_fixed)
435      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
436        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
437      - seaice_summary.F : add missing report of read turbulent flux term set up
438                           and SITRACER.
439      - seaice_check.F : check range; inform and stop if retired CPPs are used
440                         (incl. SEAICE_AGE).
441      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
442             CPP switch, same computation as before for the different options.
443      - change results at the truncation level.
444    o pkg/seaice:
445      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
446        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
447        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
448      - update verification/*/input*/data.seaice:
449        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
450        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
451        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
452        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
453    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
454      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
455        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
456        difference in results only due to machine truncation.
457      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
458        MaykutPolySatVap; keep MIN_LWDOWN.
459      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
460      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
461        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
462    o pkg/salt_plume:
463      - isolate saltPlumeFlux array exch into a specific S/R called from
464        do_oceanic_phys.F
465      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
466    o verification:
467      - move untested set-up to MITgcm_contrib/verification_other.
468    o pkg/seaice:
469      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
470    o pkg/seaice:
471      - seaice_solve4temp.F (keeping results unchanged):
472        * add 2 future run-time params to select which saturation vapor pressure
473          formula is used and how post-iteration fluxes are set.
474          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
475        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
476          the linearized expression to stay consistent with tsurf finding.
477      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
478        can be < 0.
479    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
480      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
481        conductive heat flux F_c , and add it explicitly when updating tsurf as
482        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
483        so that now F_ia has a consistent meaning through the entire routine.
484        This causes differences at truncation level: update output of fwd exp.
485        global_ocean.cs32x15.seaice.
486    o pkg/seaice:
487      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
488        of arrays, sign/direction of fluxes; no effect on results.
489      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
490        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
491        note: this should have been done before changing celsius2K default.
492      - to keep results unchanged, add back old value of celsius2K in verification
493        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
494      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
495        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
496        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
497        freezing temp is consistent with value in seaice_growth.F ; this causes
498        differences at machine truncation level: update lab_sea AD output (3/4).
499    o pkg/seaice:
500      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
501        and climsst/sss even when using seaice (to prevent calculation that might
502        use SST on land); does not affect any verification exp.
503      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
504        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
505    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
506      over land (non-legacy code)
507    o vectorize salt_plume package:
508      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
509      - this code computes plumebk everywhere (also over land), thus requires
510        code to avoid divisions by zero and catch the case of kLev=Nr.
511      - efficiency of salt_plume_frac is still sub-optimal
512    o tools (genmake2):
513      - fix makefile NAME specification (option: -makefile NAME) by adding
514        "-f $MAKEFILE" in few places where it was missing including makedepend
515        command (contribution from Paul).
516    
517    checkpoint63i (2012/01/24)
518    o model/src:
519      - add factorized versions of some EOS code to find_rho.F,
520        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
521    o model/src:
522      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
523      - change default celsius2K from 273.16 to 273.15
524      - to keep results unchanged, add back old value of celsius2K in verification
525        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
526         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
527    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
528      to make TAF generate vectorizable code
529    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
530       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
531       have flags that do this more efficiently.
532    o pkg/diagnostics/diagstats_calc.F
533      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
534    o pkg/obcs (with exch2):
535      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
536        and remove code (in obcs_readparms.F) which was based on EXCH of indices
537        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
538    o pkg/exf and seaice exp:
539      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
540        so that switching off area & heff advection flags does not affect results.
541      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
542      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
543        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
544        results of verification experiments: 1D_ocean_ice_column(fwd),
545        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
546        and offline_exf_seaice (all 4).
547    o pkg/seaice:
548      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
549        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
550      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
551        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
552        not multi-dim advection;
553      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
554        SHORTWAVE_HEATING #undef.
555    o optim: make Makefile more robust (?)
556    o pkg/obcs:
557      * fix treatment of obcs_read_pickup for TAF
558    o pkg/shelfice:
559      * add missing initialisation of num_shifwflx
560      * new adjoint verification exp. for isomip
561      * change Prandtl and Schmidt numbers from generic formulations
562        (in terms of model diffus. and visc.) to separate runtime
563        parameters, with Holland and Jenkins (1999) default values.
564    o pkg/exf (interpolation):
565      - extended input field (2 rows) near the N & S poles:
566        * fill in with the symetric value (when even Nb of data in longitude)
567        * add average value at the poles only for scalar quantities ; for vector
568          component interpolation, skip the averaging and keep duplicated values,
569          unless the 2 components have same location (uvInterp=T) in which case
570          interpolate the 2 components together using S/R EXF_INTERP_UV.
571      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
572        together: this allows to account properly for local orientation when
573        averaging at N & S pole.
574      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
575        exf-interpolation near N & S poles. Undef by default.
576      - add debug check/print on 1rst iter if debugLevel >=2.
577    o pkg/exf:
578      - change masking flags definition (no longer "parameter"), put them in
579        common block and set them in S/R EXF_INIT_FIXED.
580      - change recognized masking flag from s,u,v to c,w,s since the mask
581        to use (maskC,W,S) depends on position on model grid and has little to
582        do with scalar/vector difference; fix masking if using P-coordinates.
583      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
584        and update results of exp. global_with_exf (x2).
585      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
586    o pkg/obcs
587      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
588    o pkg/exf (interpolation):
589      - assume periodicity in X only if input field cover full longitude range.
590      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
591        and should vectorise).
592      - fix input lat of the 2 added row (in case we provide N.pole data).
593    
594    checkpoint63h (2011/12/30)
595    o pkg/seaice:
596      - change declaration of UVM from _RL to _RS in order to get B-grid
597        uIce,vIce monitor when _RS = real*4
598    o pkg/offline:
599      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
600      - compute vertical velocity if not read from file (switch on exactConserv
601        & staggerTimeStep);
602      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
603    o verification:
604      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
605        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
606        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
607      - update output of exp. global_ocean.cs32x15.viscA4 after changing
608        grid-file angles (used here for coriolis-3d);
609      - remove (or gzip) few files not needed to run fizhi-cs experiments.
610    o pkg/exf (vector interpolation):
611      - rotate vector component toward local grid-axis orientation using grid-angles
612        (stored in GRID.h) instead of locally computed rotation angle; keep old code
613        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
614    o pkg/seaice:
615      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
616        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
617    o pkg/PKG_OPTIONS.h files:
618      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
619        outside of the #ifdef ALLOW_THISPKG / #endif block.
620      - update verification/*/code/PKG_OPTIONS.h files.
621    o add a verification experiment (offline_exf_seaice/input.seaice) that test
622      the B-grid LSOR solver
623    o pkg/seaice: sort out emissivity and long wave radiation step 2:
624      - add emissivity for snow and ice as new run-time parameters
625        (unfortunately) that default to the corresponding exf values; this
626        changes results in most verification experiments so that for backward
627        compatibility these parameter have to be set explicitly to inconsistent
628        values (ugly);
629      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
630        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
631        until we agree how to handle this bug properly
632    o pkg/exf (interpolation):
633      - add a set of run-time param ({inputfield}_interpMethod), one for
634        each interpolated input field, to select the interpolation method
635        with a value of zero switching off the interpolation;
636      - print interpolation parameters to standard output;
637      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
638        (to use instead runoff_interpMethod=0 in data.exf).
639      - simplify default setting of interpolation parameters (for all fields,
640        set position to match model grid cell-center position, leading to trivial
641        interpolation in case of regular Lat-Lon grid) and fix for the case of
642        non-uniform delY.
643    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
644       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
645       this factor is absolutely required, because the lw exitance (= out-going
646       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
647       where the reflectivity rho = 1-emissivity for conservation reasons. Once
648       this is established, we can remove the CPP-Flag (if we want to).
649    o pkg/seaice:
650      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
651        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
652      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
653        what the name implies (and not emissivity*BoltzmannConstant), this means
654        the old default value of 5.5e-8 now means
655        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
656        S/R exf_readparms
657      - FV-discretization of the B-grid LSOR solver, turn on with
658        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
659        of the calling routine dynsolver, so that B and C-grid code look a
660        little more alike.
661      - fix index bugs in ostres.F (B-grid code)
662    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
663    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
664      default for SEAICE_emissivity, if useEXF; requires setting a wrong
665      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
666      backward compatiblity
667    o model/src: use sigmaR in calc_ivdc
668    
669    checkpoint63g (2011/12/16)
670    o pkg/seaice/seaice_growth.F:
671      fix heat conservation of the coupled ocean-seaice system.
672      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
673      solid vs liquid water treatment is resolved via QNET.
674    o pkg/seaice/seaice_growth.F:
675      add missing term for sublimation in saltFlux, which was breaking conservation.
676    o pkg/seaice/seaice_model.F:
677      Remove this patholigical case treatment in evolution branch,
678      where it is un-necessary and breaks conservation.
679      Update global_ocean.cs32x15/results accordingly for
680      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
681    o model/src:
682      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
683      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
684    o pkg/obcs:
685      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
686      tendency for temperature and salinity that is then applied to update
687      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
688      horizontal advection and diffusion contributions on the boundary (in
689      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
690      removing the mask in S/R timestep_tracer. The advantage of this approach is
691      that the updated tracer values include contributions from the surface
692      forcing and vertical diffusion.
693      This modification changes exp4.stevens because of vertical diffusion.
694    o model/src:
695      change non-curvilinear grid setting to also work with exch2 + blank tiles:
696      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
697        face dimensions.
698      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
699        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
700        and INI_SPHERICAL_POLAR_GRID.
701      change test-experiment global_ocean.90x40x15:
702      - split the domain in many more tiles (9x4 tiles of 10x10 each);
703      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
704      - update results of both test (std & dwnslp).
705    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
706       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
707    o model/src:
708      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
709        and fix initialisation when using sigma-coords.
710    o model/src:
711     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
712       to their current value at the beginning of forward_step.F": add a new run-time
713       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
714     - set doResetHFactors=T in the following test exp:
715        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
716        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
717        and tutorial_global_oce_in_p (nonLinFS in p)
718    o pkg/ecco
719      - added IES cost term
720    o verification/advect_xz
721      - scale down the depth by 1/100 (from 200 km to just 2.km)
722      - add secondary test using divergent flow, r-star and implicit vertical advection.
723      - add note (check_conserve_TS.txt) and matlab script to check global
724        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
725    o pkg/rbcs:
726      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
727    o pkg/obcs (Stevens BCs):
728      - fix various problems in the phase speed computations of the Stevens
729        boundary conditions:
730        - sign error for western and southern boundaries,
731        - time tendencies were underestimated by factor of dTracerLev and some just
732          zero (for multidim advection schemes) -> now estimate time tendencies
733          from difference between previous (n) time level and the one before (n-1);
734          this requires storing a field per tracer per boundary, also in the pickup
735          files.
736        - replace deltaTmom in cflMer/Zon computation with dTracerLev
737        - set default phase velocity to cflMer/Zon
738      - update verification experiment exp4.stevens
739    o pkg/generic_advdiff (implicit_r):
740      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
741        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
742      - fix implicit vertical diffusion or advection with NonLin FreeSurf
743        (was using current recip_hFacC instead of future recip_hFacC): set future
744        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
745        solver S/R ;
746      - fill diagnostics of vertical advective fluxes (computed from tendency)
747        when using implicit vert. advection;
748      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
749         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
750         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
751         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
752    o pkg/diagnostics:
753      - add diags for T & S tendency which goes through Adams-Bashforth.
754    
755    checkpoint63f (2011/11/30)
756    o pkg/obcs/obcs_calc_stevens.F:
757      - join some loops to reduce number of if-statements
758      - fix a bug in code for northern and southern boundaries.
759    o pkg/seaice/seaice_init_varia.F
760      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
761        caused zero ice-velocities for the B-grid code
762    o pkg/seaice/seaice_init_fixed.F
763      - fix a bug in the initialisation of the second metric terms
764        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
765      - this affects all seaice configurations with useCurviLinearGrid = .true.
766        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
767        = .true. (default)
768      - the only verification experiment affected is global_ocean.cs32x15:
769        icedyn, seaice, and seaice_dynmix (AD)
770    o pkg/thsice/thsice_diagnostics_state.F
771      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
772        not contain garbage that can lead to surprises in diagstats_calc.F
773    o model/src:
774      - move bi,bj loops inside INTEGR_CONTINUITY ;
775      - call INTEGR_CONTINUITY directly from forward_step.F
776        (previously called from momentum_correction_step.F)
777      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
778        forward_step.F and pkg/ecco/the_main_loop.F
779    o model/src/do_oceanic_phys.F:
780      - reset addMass to zero only if useICEFRONT ;
781      - separated k-loop for rhoInSitu calculation ;
782      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
783        and at constant T,S (= WdRHOdP);
784      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
785        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
786        transport of locally-referenced potential density);
787        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
788    o gluemnc:
789      - replace ncrcat with ncks when adding variables to *.glob.nc
790      - change the way variables without record dimensions are handled so that
791        files that have variables with and without record variables can be glued:
792        add a record dimension with a new unique name to be able to differentiate
793        between variable with and without a-prior record dimensions. Remove
794        this record dimension before adding the variable to the *.glob.nc file.
795        This procedure automatically works also for grid.*.nc files that do not
796        have any record dimension.
797    o verification/cpl_aim+ocn:
798      - generate new reference output on baudelaire (gfortran, mpich2) (previously
799        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
800    o pkg/obcs/obcs_calc_stevens.F:
801      - add code for northern and southern boundaries.
802      - reorder some loops to save some operations and so that drFBar can be scalar
803    o model/src:
804      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
805        truncation) and add diagnostics for Adams-Bashforth tendency increment.
806      - update test-exp. AD output:
807        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
808      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
809        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
810        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
811        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
812        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
813        tutorial_plume_on_slope.
814    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
815      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
816      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
817      does not even come with an F77 compiler anymore, this should not be
818      a limitation
819    
820    checkpoint63e (2011/11/06)
821    o pkg/seaice adjoint of LSR:
822      - substantially rework STORE dirs.
823      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
824        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
825        and only perform SOLV_MAX_FIXED adjoint iters.
826        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
827        always goes to same record, meaning that the last forward field will be
828        the one used in the adjoint - an approximation.
829      - now produces non-zero LSR-related gradients, and acceptable gradients for
830        An's zonal (x-z) test case (to be checked in)
831      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
832        (but these are screwed up by the thermodynamics in the first place);
833        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
834        output_adm.txt also reflects changes to seaice_lsr
835      - global_ocean.cs32x15:
836        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
837          (output_adm.seaice.txt was updated)
838        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
839          (output_adm.seaice_dynmix.txt)
840    o test-exp. exp4+stevens:
841      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
842    o pkg/seaice (lsr solver):
843      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
844        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
845      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
846      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
847        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
848      - compute (with new S/R) and print initial (+ free-driff sol. if available)
849        and final residual of linearised system.
850    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
851      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
852    o pkg/obcs: Stevens BCs (still only for east and west)
853      - fix Stevens BCs by using intermediate velocities of previous
854        time step as "baroclinic" contribution rather velocity of one grid cell
855        inside the boundaries; more consistent but makes the entire treatment
856        more complicated, requires new pickup files and two new S/Rs:
857        obcs_copy_uv_n and obcs_save_uv_n
858        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
859        (undefined by default)
860      - silently move computation of some grid factors into separate loops to
861        save some recomputations
862      - add a hack for non-linear free surface
863      - add a verification experiment to exp4 that tests this code
864    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
865    
866    checkpoint63d (2011/10/25)
867    o pkg/obcs + seaice-dynamics:
868      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
869        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
870        values (consistent with an implicit method).
871      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
872        return to older implementation (same results as before); note that none of
873        the "experimental" OBCS_SEAICE options are implemented in the new version.
874      - switch test exp. seaice_obcs to use new version (update output).
875    o pkg/seaice:
876      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
877      - add parenthesis in Water-Ice drag calculations (evp & lsr);
878      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
879        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
880      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
881        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
882    o pkg/layers:
883      - Include potential density as new coordinate (Thanks to David Munday)
884    o pkg/dic:
885      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
886        carbonate computation/output to CALC_PCO2_APPROX
887    o pkg/generic_advdiff
888      - make TAF generate code that vectorizes:
889        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
890    o model/src:
891      - improve vectorization also for adjoint code of
892        solve_tridiagonal and solve_pentadiagonal. As this requires up to
893        5 new 3D-fields, this code is only turned on for the combination of
894        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
895        for singular matrix check (only for TARGET_NEC_SX).
896      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
897        ALLOW_AUTODIFF. This flag now needs to be set outside of
898        solve_tri/pentadiagonal.F
899    o pkg/exf:
900      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
901        optional namelist EXF_NML_OBCS).
902      - add many debug-print (to trace down where pkg/cal error msg comes from)
903    o pkg/mom_vecinv/mom_vi_hdissip.F
904      - rearrange loops so that vectorization is improved and in particular
905        the adjoint routine vectorizes. The code is a little longer now, but I
906        think easier to read.
907        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
908    o pkg/seaice:
909      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
910    o pkg/exch2:
911      - alternative code (without tile x tile matrix) for cumulated (global) sum;
912        used as default; keep using matrix version in adjustment.cs-32x32x1.
913    o tools/build_options:
914      - after merging some MPI and/or multi-threads specific optfiles so that
915        the modified default optfile support both built (using genmake2 -mpi
916        for the MPI built, using genmake2 -omp for OpenMP built),
917        move now obsolete optfiles to tools/build_options/unsupported/
918       (add copy of email sent to support list in doc/optfiles_changes.txt)
919    
920    checkpoint63c (2011/09/28)
921    o pkg/ebm:
922      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
923        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
924    o pkg/seaice (SItracer pickup)
925    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
926      To be done:
927      - thorough testing of missing fields in S/R seaice_read_pickup
928      - thorough matching between generic tracers and specific fields used
929        (e.g. volume-weighted age, area-weighted age, salinity, ...)
930    o pkg/grdchk:
931      - all procs calculate and print finite-difference gradient (for testreport)
932      - change description output used by testreport;
933      - AD testing: also compare and report Finite-difference gradient;
934        => update all output_adm*.txt
935    o test exp. global_ocean_ebm:
936      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
937        and turn on exactConserve; update (fwd) output.
938    o pkg/seaice (LSR):
939      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
940      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
941        * identical results with non-CS topology (but save up to half of EXCH calls)
942        * no much changes in cs-32 verification tests since no ice at face edges
943         (differences due to convergence criteria, since nb of iterations changed)
944        * expect some differences on lat-lon-cap grid.
945        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
946    o pkg/exch2:
947      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
948        many tiles); until alternative coding is added, just add a stop.
949    o pkg/kpp:
950      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
951        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
952    o optfiles:
953      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
954        into corresponding standard one, which now support different build:
955        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
956      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
957    o pkg/obcs (seaice):
958      - add missing EXCH for uIce,vIce after applying OBCS;
959      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
960        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
961        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
962      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
963      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
964        and eedata.mth for MPI and mutlti-threaded testing.
965    o pkg/flt:
966      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
967      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
968      - fix pickup and trajectories + profiles output with multi-threads;
969      - add parameter to select group of fields to write along trajectory and
970        profile (default unchanged);
971      - only call PORT_RAND* function when flt_noise <> 0;
972      - add multi-threaded test for verification exp. flt_example.
973    o eesupp/src:
974      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
975      - USE_OMP_THREADING: check that number of threads (from eedata) matches
976        actual number (from env.var. setting).
977    o pkg/ebm:
978      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
979      - add multi-threaded test for verification exp. global_ocean_ebm
980    
981    checkpoint63b (2011/08/29)
982    o pkg/ebm:
983      - fix sign of runoff;
984      - update directly forcing fields (Qnet,EmPmR) to use standard
985        external_forcing_surf.F (remove ebm_forcing_surf.F);
986      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
987      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
988        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
989      - update global_ocean_ebm parameters file data and update output (fwd+ad).
990    o verification/matrix_example:
991      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
992        MPI and mutlti-threaded testing.
993    o pkg/matrix:
994      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
995      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
996      - fix for multi-threaded (remove DATA statement);
997      - use standard DIFFERENT_MULTIPLE function;
998      - add MATRIX_OPTIONS.h
999    o verification/matrix_example:
1000       To allow to split the domain in several tiles, change the domain size
1001        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
1002        Western side) of land points.
1003    o (*_)write_pickup:
1004      - fix few bugs in mypackage_read/write_pickup.F
1005      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
1006        array of length 1 (was caught by compiler syntax-check).
1007    o pkg/diagnostics (velocity potential solver):
1008      - fix initialisation of main diagonal matrix (for overlap values)
1009    o tools/build_options:
1010      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
1011        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
1012      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
1013        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
1014        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
1015        and use "-devel" testreport option for standard testing on baudelaire.
1016    o pkg/grdchk:
1017      - Assume that all gradient-check position are within the same tile
1018        corresponding to global indices (iGloTile,jGloTile) and that
1019        positions (i,j indices or nbeg) are local to this tile;
1020      - set tile local-indices and proc. number according to tile global-indices;
1021      - remove grdchkwhichproc from namelist (retired param);
1022      - send adjoint gradient to all procs so that all procs print it to STDOUT;
1023      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
1024    o adding package bbl (Bottom Boundary Layer)
1025      description in MITgcm/pkg/bbl/bbl_description.tex
1026      example/test experiment in MITgcm_contrib/bbl
1027    o adjoint verifications
1028      - changed 5 experiments to multi-tiles
1029        * global_ocean.90x40x15
1030        * obcs_ctrl
1031        * offline_exf_seaice
1032        * tutorial_dic_adjoffline
1033        * tutorial_tracer_adjsens
1034        changed reference output for those that crossed tile boundaries
1035        (changed choices of gradient check positions)
1036      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
1037      - temporary bug fix in grdchk_loc.F for obcs
1038    o genmake2 & testreport
1039      - add target "obj" (just for OBJFILES files) to Makefile;
1040      - add option to specify FEXTRAFLAGS on command line.
1041    o pkg/mypackage:
1042      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
1043    
1044    checkpoint63a (2011/08/02)
1045    o pkg/diagnostics (velocity potential):
1046      - fix velocity-potential calculation when using OBCS: balance net inflow
1047        at each level (new S/R OBCS_DIAG_BALANCE).
1048      - fix some of the problems with OBCS in stream-function calculation.
1049    o pkg/exf/exf_readparms.F
1050      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
1051        EXF_NML_OBCS) more consistent, so that you need not have these lists
1052        in data.exf when they are not used.
1053    o optim/optim_readdata.F:
1054      - add some output about obcs variables that might help debugging
1055      - add a check about nvarlength
1056    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
1057    o pkg/diagnostics (velocity potential):
1058      - fix mask for OBCS (still problems in stream-function with OBCS);
1059      - add specific parameter (default = main code CG2D params) for solver;
1060      - in case of poor convergence, use solution corresponding to lowest residual.
1061    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
1062      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
1063      and should be avoided where possible.
1064    o model/src (rStar):
1065      - include r* effect on reference-state (PhiRef) in totPhiHyd
1066        (so that it's really the potential anomaly at the cell center);
1067        affect solution only if z* with full pressure in EOS.
1068      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
1069        update output (because of z* in totPhiHyd and viscA4 changes);
1070      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
1071        @ constant r) until interpolation at constant r is implemented.
1072    o pkg/diagnostics
1073      - fix RCENTER diagnostics in case cell center is not at interface middle
1074    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
1075      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
1076      that THETA and SALT are "conservative temperature" and "absolute
1077      salinity"
1078    o pkg/ctrl
1079      - fix computation of endrec in s/r ctrl_init_rec
1080      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
1081    o pkg/seaice/seaice_growth.F
1082      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
1083        remove then obsolete STORE directives
1084      - fix STORE directives for tice and tices, so that only the
1085        appropriate part of the fields are stored (and not the entire
1086        field); update global_ocean.cs32x15.seaice AD output.
1087      - cosmetic changes: adjust CPP flags and indentation for better
1088        legibilty
1089    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
1090      Chris Wilson)
1091    o pkg/gmredi:
1092       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
1093       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
1094    
1095    checkpoint63  (2011/07/11)
1096    o pkg/exch2:
1097     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
1098     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
1099       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
1100       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
1101    o pkg/diagnostics:
1102     - deal with pairs of post-processed diags which are computed together; in
1103       particular, re-order list of diags within 1 file to save 2nd computation.
1104     - add S/R to compute velocity stream-function (called after velocity-potential
1105       calculation) from divergence free transport -> new diagnostics "PsiVEL".
1106     - add parameter to select grid-point location where PsiVEL == 0.
1107    o eesupp/src:
1108       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
1109       (specific S/R needed with exch2 topology - for now, just print an error msg)
1110    o pkg/shelfice
1111     - Implement friction velocity-dependent transfer coefficients following
1112       Holland and Jenkins, JPO, 1999
1113       Original code by M. Losch with small modifs.
1114       Enable with CPP option SHI_ALLOW_GAMMAFRICT
1115       and runtime flag SHELFICEuseGammaFrict
1116    o verification lab_sea & global_ocean.cs32x15:
1117     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
1118       does not miss some dependencies (but is slower) and also works with many files
1119       (default makedepend limitation for AD built).
1120     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
1121    o pkg/diagnostics:
1122     - add run-time parameter "useMissingValue" (def=False) to fill land-point
1123        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
1124       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
1125     - Extend the use of "missing_value" setting from data.diagnostics for the case
1126       of counter-diagnostics (where fraction-weight is zero). This applies both to
1127       MNC and MDS output files.
1128    o pkg/seaice/seaice_growth.F:
1129      - add 'a priori' cap of latent heat flux based on actual mass considerations
1130        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
1131        non-legacy seaice_solve4temp.
1132      - add diagnostic of the residual sublimation freshwater flux (the freshwater
1133        flux taken from the ocean if the total actual latent heat fluxes exceed
1134        the maximum)
1135      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
1136       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
1137      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
1138       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
1139      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
1140      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
1141    o verification 1D_ocean_ice_column:
1142       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
1143       update results
1144    o pkg/diagnostics:
1145     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
1146       which are not filled-up but computed from other diags ; In this case, the mate
1147       diag points to the primary (filled-up) diag to used for post processing.
1148     - Update Velocity-potential computation using post-processed diag framework.
1149     ==> Change the ordering of fields and time-periods in MDS output file
1150       when using periodic averaging: now writes one time record with the full set
1151       of fields for this time period, then the next time reccord (it used to be
1152       one field with the full set of time records then the next field).
1153         Note: this is now similar to NetCDF (MNC) output file. <==
1154    
1155    checkpoint62z (2011/06/21)
1156    o adjoint monitor:
1157     - Add adjoint monitor output for packages exf, seaice
1158       and update relevant testreport output
1159    o pkg/seaice:
1160     - re-order diags inits so that they appear in order in available_diagnostics.log
1161     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
1162       area/heff/hsnow preceeding thermodynamic growth/melt.
1163     - modified diag: SIdA; output actual effect, as the description states.
1164     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
1165     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
1166       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
1167        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
1168     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
1169     - added diagnostics for seaice generic tracers (SItr*).
1170     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
1171     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
1172     I. Fenty: 18-Jun-2011:
1173     Minor changes to seaice package:
1174     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
1175        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
1176       - Differentiated "regularization variables" from "floor variables"
1177        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
1178        * hiceMin became SEAICE_hice_reg (old hiceMin)
1179          (with _reg meaning regularization variable)
1180       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
1181        so as to ensure energy conservation when going between phases
1182      - A22 was not used anywhere
1183     2) Changed regularization procedure for heffActual and hsnowActual to ensure
1184        well-boundedness and smooth adjoint in seaice_growth.F
1185     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
1186        because the old regularization always set heffActual >= 0.05 cm
1187     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
1188        on AREA when HEFF > 0.
1189      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
1190        requiring that DISABLE_AREA_FLOOR *not* be defined
1191     Affected verifications:
1192      - 1D_ocean_ice_column (output.txt output_adm.txt)
1193      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
1194    o pkg/diagnostics:
1195      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
1196      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
1197        (was _RL, now integer) with option = 0 to retrieve all levels.
1198      - add pieces of code to compute velocity potential at each level (new diagnostics
1199        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
1200        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
1201      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
1202        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
1203        and in diagnostics_fract_fill.F (do not need a valid pointer for the
1204        diagnostics counter-mate); check that definition of counter-diagnostic
1205        includes a valid counter-mate (in diagnostics_set_levels.F).
1206    o model/src (rStar):
1207      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
1208        affect solution only if z* with full pressure in EOS;
1209        update output of test-exp global_ocean.90x40x15.
1210    o pkg/seaice:
1211      - introduce siEps=1e-5 parameter
1212      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
1213      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
1214      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
1215        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
1216        as well as ice cover age and ridging index (attached to AREA).
1217        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
1218        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
1219        Up to SItrMaxNum=3 tracers can be used simultaneously.
1220    o pkg/salt_plume:
1221      -introduce SPsalFRAC run time parameter that sets the fraction of the
1222       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
1223       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
1224    o model debug options:
1225      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
1226        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
1227      - Refine debug-msg printing selection (3 new levels):
1228        debugMode  : controls printing of debug messages (sequence of S/R calls).
1229        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
1230         debLevZero =  0 ; /* level of disabled aux. msg printing */
1231         debLevA =  1 ; /* level of minimum  aux. msg printing */
1232         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
1233         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
1234         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
1235         debLevE =  5 ; /* level of extensive debug printing */
1236        New debugLevel default: with default debugMode value (=F),
1237          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
1238          and if debugMode=T, default debugLevel = 4 (debLevD).
1239        Relation with previous settings:
1240         debLevB (=2) corresponds to former debLevA (=1)
1241         debLevD (=4) corresponds to former debLevB (=2)
1242        Note:
1243         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
1244         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
1245            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
1246      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
1247        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
1248    o pkg/obcs:
1249      - change OBCSfixTopo default from True to False (should not change the results);
1250        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
1251    o pkg/thsice:
1252      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
1253        2nd layer seaice sublimation (unlikely to happen)
1254      - use Interior mask for OBCS in thsice_advection.F (similar to what is
1255        done in gad_advection & seaice_advection).
1256    o adjoint:
1257      bug fix spotted by Gael Forget:
1258      seaice_advection and thsice_advection still had
1259      legacy CPP options to avoid CS corner updates for adjoint
1260    o pkg/seaice:
1261      => Change some of the defaults (2011/05/29):
1262         - change SEAICEuseFluxForm default (from False to True)
1263         - change DIFF1 default (from 0.004 m/s to 0. m/s)
1264         And print warnings if DIFF1 is not set in data.seaice and centered
1265          avection scheme is used without any diffusion.
1266      also:
1267      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
1268      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
1269      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
1270        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
1271        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
1272      update results of test exp.:
1273         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
1274             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
1275             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
1276         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
1277         seaice_obcs: output (SEAICEuseFluxForm=T)
1278      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
1279          for standard fwd & AD lab_sea tests (to keep the same output).
1280    o pkg/seaice/seaice_growth.F:
1281      - use Ian Fenty's capping formulas for actual ice
1282      thickness thoughout EVOLUTION branch.
1283      - put treatment pathological case #2) in CPP brackets
1284      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
1285      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
1286    o pkg/seaice:
1287      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
1288      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
1289      also pass fac as a param, which can be 1. (to update the tendency
1290      field) or the time step (to update the field itself).
1291      - seaice_advdiff.F: for multidim, call seaice_diffusion with
1292      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
1293      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
1294      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
1295      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
1296    o pkg/seaice:
1297      diffusion with centered advection scheme (diffus.F & advect.F):
1298      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
1299        to just compute the laplacian of input-field.
1300      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
1301      - fix flux-form version in diffus.F to conserve tracer.
1302      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
1303       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
1304    
1305    checkpoint62y (2011/05/26)
1306    o pkg/seaice:
1307     - seaice_growth.F : in EVOLUTION branch, always include
1308       a_QSWbyATM_cover in qnet (as it should be).
1309     - verification/global_ocean.cs32x15 : update results accordingly
1310       (output.seaice.txt output_adm.seaice.txt).
1311    o pkg/seaice + obcs:
1312     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
1313       equivalent of assuming no tracer gradient outside the OB region.
1314       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
1315     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
1316       after changes above);
1317     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
1318       only at OB location (instead of over a band of OLx width).
1319    o pkg/seaice:
1320     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
1321       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
1322    o pkg/obcs:
1323      - split header file "OBCS.h" into 4 separated files:
1324        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
1325       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
1326         (contain no conditional statement which depends on OBCS options).
1327      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
1328        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
1329    o ctrl, cost, grdchk & autodiff pkgs:
1330      - make options file more standard (like other {PKG}_OPTIONS.h file but
1331        with AD_CONFIG.h); clean-up some of the included header files.
1332    o pkg/obcs:
1333      - do not mask tracer when applying OB (tracer == 0 could generate problems)
1334      - apply tracer OB values to tracer field only at OB location (instead of
1335        over a band of OLx width)
1336      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
1337      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
1338        obcs_apply_tloc.F & obcs_apply_sloc.F
1339    o obcs in model/src:
1340      - call OBCS_APPLY_W only if NonHydrostatic.
1341      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
1342      - reset dEtaHdt and wVel to zero outside OB interior region ;
1343      - leave tracer unchanged outside OB interior region: This has no effect
1344        on the solution but just to prevent unrealistic tracer value outside OB.
1345      - zero out velocity outside OB interior region: This has no effect on
1346        the solution but just to prevent unrealistic velocity outside OB.
1347    o obcs and non-lin free-surf:
1348       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
1349       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
1350       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
1351       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
1352       update results of test-exp. exp4(nlfs).
1353    o exp4 (nlfs) test-exp:
1354       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
1355       with NonLin-FreeSurf); update output.nlfs.txt
1356    o obcs and 2d/3d solver norm:
1357       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
1358       and outside OB interior region (will allow to place OB further inside the
1359       domain). Depending on the domain, can affects cg2d-Norm (previous
1360       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
1361       and cg3d-Norm (previous Norm was computed before canceling OB terms),
1362       e.g. in tutorial_plume_on_slope.
1363      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
1364    o pkg rbcs:
1365      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
1366      - add capability to apply relaxation to horizontal velocity uVel & vVel.
1367    o pkg/grdchk: add gradient check for control variable xx_shifwflx
1368    o pkg/shelfice/shelfice_init_fixed.F
1369      fix CPP-flag combinations
1370    o pkg/seaice: Merge iceage code of Pierre Rampal
1371      * update/change/correct ice age calculations
1372      * add age updates for pathological cases
1373      Probably needs more testing...
1374    
1375    checkpoint62x (2011/05/13)
1376    o pkg/mom_vecinv:
1377       high-order vorticity scheme: use interior masks (maskInW & S)
1378       to zero-out (outside OB) gradient of vorticity.
1379    o verification exp.:
1380       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
1381       hs94.128x64x5 and seaice_obcs ; update results.
1382    o pkg/obcs:
1383      fix bug in OBeta for YZ sections in obcs_exf_load.F
1384    o pkg/ctrl, pkg/shelfice, and optim:
1385      - add new control variable xx_shifwflx (fresh water flux underneath ice
1386        shelves). This is almost as tedious as obcs-ctrl, because the
1387        variables needs its own mask.
1388      - add a cost function term that penalizes the deviation of xx_shifwflx
1389        from the first guess (zero) in analogy to other control variables
1390    o pkg/shelfice:
1391      - start basic adjoint
1392    o pkg/ctrl:
1393      - remove extra 2D field "for good measure" when initializing in
1394        ctrl_set_globfld_[xy/xz/yz].F
1395      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
1396      - improve error messages in ctrl_set_unpack_*
1397    o OBC implementation in momentum:
1398       use interior masks (maskInC,W & S) in momentum S/R:
1399       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
1400       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
1401       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
1402       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
1403       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
1404        (and also with Leith/Smagorinsky harmonic-viscosity).
1405       Update output of experiment dome and exp4 (+nlfs).
1406    o exp4 test-exp:
1407      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
1408        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
1409        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
1410        time-varying OB at Western-side for wVel (NonHyd); update output.
1411      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
1412        and biharmonic-viscosity ; also use prescribed time varying OB.
1413    o pkg/obcs:
1414      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
1415    o model/src:
1416      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
1417      - initialise startTime & nIter0 with unlikely values: allows to set one
1418        from the other without ambiguity.
1419    o seaice_obcs test-exp.:
1420      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
1421    o pkg/obcs:
1422      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
1423        no longer needed with maskInC,W,S in pkg/generic_advdiff.
1424    o pkg/seaice:
1425      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
1426        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
1427      - fixed bug in the initialization of sea ice salinity variable HSALT
1428        in seaice_init_varia.F  (removed dependence on ICE2WATR)
1429    o fizhi-cs test exp.:
1430       switch reference output convention for these 2 non-standard test-exp,
1431        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
1432          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
1433       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
1434    o model/inc:
1435      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
1436        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
1437    o pkg/seaice:
1438      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
1439    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
1440      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
1441        and initial HSALT
1442    
1443    checkpoint62w (2011/04/26)
1444    o pkg/mom_fluxform:
1445      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
1446      - use parameter "sideDragFactor" in no-slip BC side-drag part.
1447      - update output of exp. global_ocean.90x40x15
1448    o pkg/mom_vecinv:
1449      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
1450    o update seaice exp.:
1451      use more consistent parameter values (remove "backward compatability only":
1452       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
1453      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
1454       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
1455    o update test-exp global_ocean.90x40x15:
1456      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
1457      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
1458      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
1459      o turn on zStar & viscA4 in standard set-up (dir input/)
1460        and update output files: output.txt & output.dwnslp.txt
1461    o new AD-test experiment: obcs_ctrl
1462      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
1463    o pkg/dic:
1464      fix two bugs in handling water vapour pressure in carbonate chemistry
1465      and air-sea fluxes. Found by Val Bennington and Galen McKinley
1466      (add DIC Option = WATERVAP_BUG to recover old results)
1467      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
1468    o adding allowInteriorFreezing option to check for water below freezing point
1469      at depth and bring the negative heat anomaly to the surface level
1470    o pkgs _fields_load:
1471      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
1472      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
1473        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
1474        rbcs to get interpolation weights and time reccord number.
1475      - fix multi-threading in aim_fields_load.F
1476      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
1477    o external_fields_load:
1478      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
1479       interpolation weights) to use in a periodic time-series ; do not divide by
1480       time-step to convert to integer:
1481       - this fixes case where externForcingPeriod is not multiple of time-step
1482          (Thanks to Christopher L. Wolfe)
1483       - this fixes case where externForcingPeriod is an odd multiple of time-step
1484         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
1485      store index of time-record which is currently loaded:
1486       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
1487       - needed for the adjoint but not yet used because of extensive recomputations;
1488         (to be fixed soon)
1489    
1490    checkpoint62v (2011/04/02)
1491    o verification/1D_ocean_ice_column added to test Ian Fenty's
1492      pkg/seaice_growth.F modifications for improving sea ice code differentiability
1493    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
1494      (new velocity statistics after changing maskInW & maskInS definition)
1495    o pkg/generic_advdiff with OBCS:
1496      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
1497      equivalent to assumption of no tracer gradient outside the OB region.
1498      This will affect the results if using obcs+biharmonic diffusion.
1499      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
1500    o pkg/obcs:
1501      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
1502      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
1503      in Interior region. No impact on solution but affects Velocity monitor stats.
1504    o pkg/ptracers (adjoint)
1505      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
1506      tape file for each tracer
1507    o model/inc/src and pkg/autodiff: add parameters that allow to turn
1508      of parts of the adjoint code at run time. For now, there are only
1509      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
1510      parameters are set in data.pkg.
1511      This is the lazy coward's version of doing this, but still useful for
1512      debugging. In order to do it right, everything needs to be moved to
1513      pkg/autodiff.
1514    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
1515      the end; this fixes the adjoint balancing code for open boundaries.
1516    o pkg/ctrl:
1517      - change behavior of xx_${varname}period to be analogous to exf-conventions:
1518        xx_${varname}period =   0.,  means time-independent control part
1519        xx_${varname}period = -12., means one-year-periodic monthly control part
1520      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
1521        clean up ctrl_init a little, remove unused variables
1522      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
1523      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
1524    
1525    checkpoint62u (2011/03/15)
1526    o model/src:
1527      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
1528        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
1529      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
1530        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
1531    o pkg/ctrl/obcs/ecco:
1532      - remove obsolete, unused, and partially broken code:
1533        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
1534        ALLOW_CTRL_OBCS_BALANCE
1535      - put a stop statement into ecco/cost_obcsvol.F, but also add
1536        cost_obcsvol to ecco_ad_diff.list
1537    o pkg/ecco: fix counting cost function contributions for obcs (code
1538      by Matt M.) and diffkr for diagnostics
1539    o pkg/ecco, pkg/ctrl, pkg/grdchk:
1540      add cost penalty terms for initial uvel, vvel, eta controls
1541      and I/O for prior error files
1542    o pkg/mdsio:
1543       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
1544       (new argument) to check for tiled file in mdsioLocalDir : this fix the
1545       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
1546    o pkg/ctrl:
1547     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
1548       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
1549       unused and superfluous variables
1550     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
1551    o pkg/ecco
1552     - enable adjoint of Stevens OB
1553    o pkg/ctrl/ecco/grdchk:
1554      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
1555        Fortunately, we do not have any tests for the numerous cpp-flagged
1556        option of "obcs as control parameters" so we will never know
1557        if this is an improvement (but at least now things compile).
1558      - remove an obsolete initialization from ecco_cost_init_barfiles.F
1559      - fix some problems within never used ifdefs to make the code compile
1560    o pkg/obcs:
1561     - Refine Interior mask definition to work with more complex OB (e.g.
1562       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
1563       read in Interior mask from file. Check if Interior mask is consistent
1564       with OB list of indices.
1565    o pkg/seaice
1566     - beginning code for a seaice tracer package,
1567       but currently only used for seaice age: SEAICE_AGE
1568       SEAICE_num = 4
1569       iTracer = 1: area-weighted ice age
1570               = 2: volume-weighted ice age
1571               = 3, 4: template for one-year vs. multi-year ice
1572       data.seaice has new namelist SEAICE_PARM03 for arrays related to
1573       SEAICE_num
1574    
1575    checkpoint62t (2011/03/05)
1576    o pkg/obcs:
1577     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
1578       then normal component. This ensures that the normal component is set
1579       correctly even when it conficts with tangential setting from an other OB.
1580       Affects results of test-experiment seaice_obcs: update the output.txt
1581    o pkg/obcs:
1582     - add code to monitor statistics of dynamical fields at OB.
1583     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
1584       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
1585       - change default: balance the Net inflow through all OB (instead of balancing
1586         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
1587     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
1588       to match Nortern OB inflow (OBCS_balanceFacN=0).
1589    o pkg/seaice:
1590     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
1591    o pkg/seaice (seaice_growth v 1.113):
1592     - reverting seaice_growth to v 1.111 in order to have code with exact bit
1593       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
1594       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
1595       runtime flag SEAICEareaFormula is kept but is inactive
1596    o model/src:
1597     - add new param to scale curvilinear grid distance and area when using
1598       a different sphere radius from the grid-files.
1599     - test/check multi-threads EXCH applied to local variable (cg2d_x)
1600    o adjoint:
1601     - enable adjoint of Stevens OB
1602     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
1603       (a bit delicate because of potentially modified adj. common block structure;
1604       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
1605    
1606    checkpoint62s (2011/02/15)
1607    o pkg/seaice (seaice_growth v 1.112):
1608     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
1609       computing the ice cover tendency from effective thickness tendencies. Include
1610       Ian Fenty's formula.
1611     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
1612       SEAICEareaFormula.
1613     - simplify notations for the various d_HEFF/d_AREA terms.
1614    o pkg/gmredi:
1615     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
1616       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
1617       add a verification test-run (front_relax.bvp) to test GM_useBVP.
1618    o pkg/seaice (seaice_growth v 1.111):
1619     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
1620     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
1621       also melt ice.
1622    o pkg/seaice:
1623     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
1624     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
1625    o pkg/cheapaml:
1626     - from Nico Wienders: New version of this package.
1627    o pkg/flt:
1628     - add CPP options to prevent floats to re-enter the opposite side of
1629       a periodic domain (default: keep periodicity)
1630    o pkg/gmredi:
1631     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
1632       (needed for multi-dim advection).
1633     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
1634    o model/src:
1635     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
1636    o tutorial_tracer_adjsens
1637     - extend to NLFS and replace maskC by hFacC
1638       (change reference output accordingly)
1639    
1640    checkpoint62r (2011/01/24)
1641    o testreport:
1642     - add option -deloutp (-do) to remove output file after successful run
1643     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
1644       extract exact list of procs from this file ; adjust COMMAND by
1645       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
1646    o pkg/ecco: replace old ineffective way of penalizing deviations from
1647      first guess (of obcs) with code by Matt Mazloff
1648    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
1649      exf/cal
1650      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
1651        and handle case of obcs?period == 0
1652        Not affected by these changes: There is still an inconsistency in
1653        the computation of start/endrec for the obcs variables for ALLOW_CAL
1654        defined (see comment by Menemenlis, 7-Mar-2003)
1655      - make S/R ctrl_get_gen_rec return something meaningful even if
1656        ALLOW_CAL is not defined
1657      - ctrl_getobcs?: simplify code so that it does not need to use
1658                       S/R exf_swapfields
1659    o testreport:
1660       allow to test MPI with different number of processors for each experiment:
1661       create file "SIZE.h.mpi" in each build dir.
1662       Note: update of "-command" argument not yet implemented.
1663    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
1664      alleviate the need for additional 3D tapes when using
1665      the non-inear free surface in the adjoint. This is done
1666      by adding an 'update' of hfacc etc. to their current
1667      value at the beginning of forward_step.F.
1668    o pkg/seaice
1669      seaice_lsr: move stress-divergence computations out of outer pseudo-
1670      timestepping loop
1671    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
1672      up, so that the calls of the ctrl_* subroutines are really at the end
1673      of the routine.
1674    o pkg/gmredi:
1675      allow to specify a 2-D horizontal map and a 1-D vertical profil
1676      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
1677    o pkg/seaice:
1678      move lsr iterations from seaice_dynsolver to seaice_lsr.
1679    o pkg/seaice:
1680      reduce memory footprint of seaice mutldim advection tapes,
1681      by using a 2D tape independent of the generic_advdiff ones,
1682      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
1683    
1684    checkpoint62q (2010/12/29)
1685    o model/src:
1686      - check horizontal grid-spacing for unset or zero/negative values.
1687      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
1688    o pkg/flt:
1689      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
1690      - precision of input and output files set according to readBinaryPrec
1691        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
1692      - initial float position from tiled file was not converted to index space
1693        (looks like a bug): fixed to make it similar to initial pos. global file.
1694    o global_ocean.cs32x15:
1695       change SIZE.h of AD set-up to get same tiling as with MPI.
1696       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
1697    o model/src:
1698       add flag to control printing of domain fields (bathymetry, hFac ...) in
1699       ini_mask_etc (call to plot_fieds_xy*).
1700    o pkg/thsice:
1701       if useEXF, some forcing fields are not valid in overlap: fixed by computing
1702       over the interior only + apply EXCH at the end (like with SEAICE advection).
1703    o pkg/mdsio:
1704      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
1705        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
1706      - change barrier call for safe multi-threads access to 3-D shared buffer.
1707      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
1708      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
1709        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
1710    o pkg/flt:
1711      - add fourth-order Runge-Kutta integration
1712      - add basic exch2 support (only 1 facet supported so far!)
1713    o pkg/mdsio+rw:
1714      new S/R to read local (or tile independent) vector (read counterpart of
1715       mds_writevec_loc, and front-end write_glvec_rl/rs).
1716    o global_ocean.cs32x15: additional input_ad.seaice experiment
1717        that uses pkg/seaice rather than pkg/thsice.
1718        (using multidim advection for seaice)
1719    o towards more F95 syntax for array specification in namelist:
1720      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
1721        of all verification experiments.
1722           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
1723          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
1724      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
1725    o global_ocean.cs32x15: additional input.seaice experiment
1726        that uses pkg/seaice rather than pkg/thsice.
1727    
1728    checkpoint62p (2010/12/17)
1729    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
1730        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
1731    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
1732        allow for use of multim. advection in seaice adjoint.
1733    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
1734      - first attempt to close budgets by taking into account the freshwater
1735        flux implied by the sublimation of snow and ice. So far only the
1736        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
1737        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
1738    o eesupp/src:
1739      new S/R with new option (NML_EXTENDED_F77) to change array specification
1740      from F95 standard to commonly accepted extended F77 form.
1741      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
1742      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
1743      for less tolerant f77 compiler (e.g., pgf77, g77).
1744    o globalFiles:
1745      commented out in parameter file "data" since it's not safe with MPI
1746      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
1747      in this case); no longer commented out in restart test (tst_2+2).
1748    o add adTapeDir to specify a special directory where adjoint tapes are
1749      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
1750      and cannot be used together with mdsioLocalDir.
1751    o nesting pkgs:
1752      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
1753      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
1754      - add parameter files + utils dir + output from short run on beagle.
1755    o pkg/seaice:
1756        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
1757    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
1758      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
1759    
1760    checkpoint62o (2010/11/25)
1761    o pkg/exf:
1762      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
1763    o pkg/seaice:
1764      - seaice_ocean_stress: split a loop for better vectorization of the
1765        adjoint code
1766      - seaice_growth.F: fix bug in conservation of freshwater connected to
1767        capping of heff, put contribution into d_HEFFbyNEG
1768      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
1769        by something more sensible (parameters that are what their name implies)
1770      - change some defaults, so that by default exf-parameters are used for
1771        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1772        to reproduce the old results, many data.seaice now contain funny values
1773        for cpAir and latent heat of sublimation
1774    o packages_readparms.F: move exf_readparms up in line so that
1775        exf-parameters are visible for other packages (e.g. seaice)
1776    o debugMode & debugLevel=2:
1777      - differentiate between debugMode & debugLevel=2:
1778        debugMode: controls printing of debug messages (sequence of S/R calls).
1779        debugLevel: controls printing of algorithm intermediate results and stats.
1780      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1781        => allows to print debug-stats without all sequence of call messages.
1782      - switch control of debug print from debugLevel to debugMode in many S/R.
1783    o pkg/obcs (obcs-sponge):
1784        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1785        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1786    o pkg/generic_advdiff:
1787      - record overlap minimum size for each advection scheme;
1788      - refine criteria on overlap minimum size;
1789      - check and stop (in gad_check) if overlap size is too small.
1790    o pkg/obcs:
1791      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1792        once, in ptracers_implicit.F)
1793      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1794        apply OB values when tile has OB)
1795    o model/src, coriolis setting:
1796      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1797        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1798        files (selectCoriMap=3) with any grid.
1799      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1800    o pkg/seaice/seaice_growth.F:
1801        a few cosmetic changes that reduce the number of lines of code
1802    o pkg/obcs: add boundary conditions following Stevens (1990)
1803      - the code follows old MOM/NAOSIM code
1804      - so far it is only implemented for the eastern and western boundaries
1805        and NOT for pTracers
1806    o pkg/rbcs:
1807      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1808        beginning of the first rbcs forcing period.
1809      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1810        offline package, i.e., one file per time, labeled by iteration number;
1811        deltaTrbcs sets the timestep with which the data was generated;
1812        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1813      - rbcsForcingCycle=0 makes forcing non-cyclic.
1814      - make arithmetic safe for negative times and odd forcing periods.
1815    
1816    checkpoint62n (2010/11/09)
1817    o pkg/seaice:
1818        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1819    o pkg/obcs:
1820       New S/R to copy tracer value from the OB location to narrow band region
1821        (width = same as overlap) beyond the OB: preserve OB value (needed for
1822        high-order scheme) which were overwritten by EXCH call if in overlap
1823        region. Applied to theta, salt, ptracer and advected seaice variables.
1824       With seaice: use maskInC in similar way as in gad_advection.F,
1825        in seaice_advection.F and advect.F.
1826       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1827        4th order Adv.Scheme. for pasive salt and ptracer.
1828    o tools/genmake2:
1829      - when looking for an optfile (not specified), only search for Fortran compiler
1830        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1831      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1832        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1833      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1834        an optfile, but otherwise default was just "cpp".
1835      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1836      - when "CC" is not set in the optfile, look for possible C compiler
1837        (instead of just setting CC=cc)
1838      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1839        => add a ".F" to ".o" rule for source files with no "#include" (such as
1840           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1841      - move gfortran before g77 in list of possible Fortran compiler (consistent
1842        with reference compiler switch from g77 to gfortran)
1843    o pkg/seaice:
1844      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1845        seaice_check that stops the model, when the CPP flag is used.
1846      o seaice_growth.F: make capping of ice volume conserving by returning the
1847        capped ice as freshwater to EmPmR. This does not change the verification
1848        experiments but will change runs where the capping is acutally active
1849    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1850      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1851         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1852         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1853    o tools/genmake2:
1854      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1855      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1856      - clean previous genmake log files before anything else.
1857      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1858        files only with "CLEAN" target (instead of "Clean");
1859    o pkg/generic_advdiff:
1860      Change OBCS in multiDim advection (gad_advection.F):
1861       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1862       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1863       which were applying future time-step OB values.
1864      This way, all explicit calculations use current-time-step OB values
1865       (simpler and more consistent).
1866      Affects results when set-up uses time-varying OBC and multi-dim advection;
1867       update output of experiment seaice_obcs.
1868    o pkg/seaice:
1869      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1870       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1871         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1872      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1873       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1874       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1875    o pkg aim (2010/10/26):
1876      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1877        formulation with obliquity, eccentricity, ... as run-time parameters,
1878      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1879        upward shortwave radition at the surface (all-sky and clear-sky).
1880    o pkg/obcs:
1881      - writing sections with globalFiles=T does not work: switch to tiled-files
1882        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1883      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1884      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1885    
1886    checkpoint62m (2010/10/21)
1887    o pkg/seaice: vectorize seaice_solve4temp.F
1888      - move iterations loops outside of i/j-loops
1889      - requires 2D arrays for TB and effConduct
1890      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1891        modified in this routine
1892      - a little bit of clean up, adjusting indentation, etc.
1893      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1894        performance and '**TWO' by '**2' (because TWO is a float),
1895        replaced ONE, ZERO
1896    o eesupp/src:
1897       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
1898    o pkg/seaice/seaice_growth.F
1899      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
1900      merging process. The merged routine has two branches, and one activates the 'evolution'
1901      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
1902      In summary, here is what the '10/10 revision' did consist of
1903        part 1: seaice_growth.F revisions 1.71 to 1.75
1904          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
1905            The emphasis here was on improving readability (e.g. by trying to use meaningful
1906            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1907        part 1.5:
1908          - revising the lab_sea experiment to make it a more useful (i.e. stable
1909            and representative of an actual model run). This was done by generating a
1910            (winter) pickup to start from, switching back the main experiment dynamic
1911            solver from evp to lsr, having one of the experiments use the free drift solution.
1912        part 2: seaice_growth.F revisions 1.76 to 1.85
1913          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1914          - Sorting out the various fields units and sign (set early on and reset at the end)
1915            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1916            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1917          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1918            and simplifying logical expressions to further improve readibility.
1919        part 3: seaice_growth.F revisions 1.86 to 1.89
1920          - Re-organize the blocks of code more logically.
1921          - Merging the '_if.F' pieces that add something new.
1922    o pkg/thsice:
1923      - vectorize thsice_solve4temp and thsice_get_exf.
1924        Problem: thsice_solve4temp has an unvectorizable statement that
1925        might also be problematic for TAF
1926      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1927        does not change the verifcation experiment, but will change all
1928        experiments that have this flag undefined (not tested in verification);
1929        a little reorganization to save a few 2D fields and recomputations
1930      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1931      - 2nd step:  fix some store dirs
1932        o seems to work somewhat, i.e. using ifort but not g77
1933        o likely cause are incomplete init. or recomputation
1934        o start verification/global_ocean.cs32x15/input_ad.thsice
1935    o pkg/obcs: add support for exch2
1936      - the position of the boundary and prescribed values are specified using
1937        a global domain with exch2 facets stacked
1938        - in x for N,S boundaries (like W2_mapIO=-1)
1939        - in y for E,W boundaries (so E,W boundaries do not overlap)
1940    o pkg/mdsio: add support for writing global sections with exch2
1941        file layout is as for obcs described above:
1942        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1943        - for y-z sections, facets are stacked in y
1944    o pkg/thsice:
1945       - change a few routines for better vectorization: thsice_albedo.F,
1946         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1947         not affected, but in particular the latter routine has changed
1948         dramatically (not necessarily easier to read now).
1949       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1950       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1951    o verification/lab_sea:
1952      - overhaul of the forward model experiments. The main motivation
1953        for this revision is that lab_sea has proven quite fragile (when
1954        changing the sea-ice code, and switching platforms) to a point
1955        when failures were very hard to attribute to specific code problems.
1956      - the suspected reason for this fragility is noise amplification by evp so,
1957        to start with, we decided to replace evp with lsr in the main experiment.
1958      - the input.lsr experiment thus became obsolete and was removed.
1959      - it was replaced with the input.fd experiment that uses an
1960        analytical "free drift" solution as the ice velocity field.
1961      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1962        will hopefully allow us to discriminate problems due to dynamic solvers
1963        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1964        us to test additional options, along with the salt plume package.
1965      - Finally a pickup was generated (at the end of a one year run) to
1966        make the tests more representative of an actual model run. Previously
1967        the tests starting point was a 1m thickness of ice everywhere.
1968    o pkg/seaice:
1969      - introducing S\R seaice_freedrift.F that compute the
1970        analytical solution to an approximate ice momentum
1971        equation (i.e. the simple stress/coriolis balance).
1972      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1973        of the free drift velocity field, and enable its use.
1974        To actually use the free drift solution as the model ice
1975        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1976    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1977    
1978    checkpoint62l (2010/10/04)
1979    o pkg/seaice:
1980      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1981      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1982       version (with USE_ORIGINAL_SBI undef);
1983    o add hooks for new packages OASIS, the package will follow
1984      (hooks exclude the seaice pkg for now)
1985    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1986      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1987      rather than mdsio_readvector.F/mdsio_writevector.F, within
1988      adread_adwrite.F to read/write adjoint-related tapes to disk.
1989    o eesupp and pkg/mdsio: ALLOW_WHIO
1990      Option to write/read 2D fields to files including tiles halos.
1991      The main purpose is for adjoint related "tape I/O".
1992      The secondary purpose is for debugging phases.
1993      A word on those rather specifically intended purposes.
1994      The code was meant to be stripped down to the bare minimum.
1995      Typically, there is a unique and basic mapping to the global
1996      buffer (tile by tile, then proc by proc, then level by level), and
1997      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1998      meant to generate user friendly outputs of various shapes and forms.
1999      Rather it is intended, for the knowledgeabale developers,
2000      to be largely independent of the many mdsio options, to allow
2001      outputs of tiles+halos in debugging phases and in adjoint runs,
2002      and to allow some flexibility in tuning (adoint) I/O depending on each
2003      file system behavior. With regard to tuning, most of the potential knobs
2004      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
2005      to specify directories, to specify the typical size of I/O calls, etc.)
2006      are not yet included, and will be added if they prove useful.
2007    o pkg/seaice:
2008       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
2009    o pkg/seaice:
2010       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
2011       code (seaice_budget_ice_if.F) which enable to recover old standard
2012       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
2013       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
2014    o model/src (rStar):
2015       use simple average (not area weighted) of rStarFac at U,V point when using
2016       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
2017       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
2018    
2019    checkpoint62k (2010/09/17)
2020    o adjoint
2021       * changed verification/global_ocean.cs32x15 ; adjoint now tests
2022         Adams-Bashforth 3 + NLFS + RSTAR
2023       * some more modifs required for ECCO-GODAE v4
2024    o pkg/seaice
2025       add SEAICE_AGE_VOL option to use volume instead of area for
2026       integrating SEAICE_AGE
2027    o model/src:
2028       first check-in of sigma & hybrid-sigma coordinate code ; also includes
2029       non-linear free-surface parts ; but pressure-gradient not yet coded.
2030    o pkg/ptracers:
2031       option for ptracer to convert Salt Relax into additional EmP.
2032        tested in exp. global_ocean.90x40x15.dwnslp (update output)
2033    
2034    checkpoint62j (2010/08/25)
2035    o pkg/ggl90:
2036       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
2037    o pkg/dic: car_flux.F, phos_flux.F
2038      - reduce number of exp-calls in order to improve performance
2039      - clean up a little (replace fields by their macros, etc., fix
2040        typo in CPP-flag)
2041    o pkg/ggl90: minor changes
2042      - GGL90diffKrS was removed --> always use GGL90diffKr
2043      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
2044      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
2045        (commented out for now)
2046      - change in max/min operations to ensure that smoothing is ok
2047      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
2048      - always use diffKrNrT as background profile (i.e. never use diffKr field)
2049    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
2050    o pkg/dic:
2051      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
2052        vectorization
2053      - small bug fix in insol for the unlikely case of a cartesian grid
2054      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
2055        + now vectorize, which also removes adjoint recomputations;
2056        + replace integer maksp1 by _RL maskp1
2057        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
2058    
2059    checkpoint62i (2010/07/21)
2060    o pkg/flt:
2061      - with OBCS: stop floats which enter the OB region
2062    o model/src:
2063      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
2064        for implicit vertical advection.
2065    o pkg/seaice:
2066     - account for melting in seaice age evolution.
2067     - remove double counting of seaice ridging effect on seaice age.
2068    
2069    checkpoint62h (2010/06/18)
2070    o pkg/exch2:
2071     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
2072    o tools/genmake2
2073      - remove "-pdefault" option: redundant with the use of "packages.conf";
2074      - remove file pkg/pkg_default : set the default as a pkg group
2075        ("default_pkg_list") defined in pkg/pkg_groups;
2076      - fix for case pkg/pkg_depend is missing (was hanging before);
2077      - add option "-pgroups" to specify a different pkg_groups than the default.
2078    o verification/adjustment.cs-32x32x1:
2079       add a "minimal" set-up test (code_min & input_min) which only compiles
2080       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
2081    o tools/genmake2
2082      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
2083      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
2084    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
2085      files are nearly the same anyway.
2086      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
2087       - redefinition of tau(i,i) (by a factor of ustar)
2088       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
2089       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
2090       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
2091       - replace
2092         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
2093         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
2094         by
2095         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
2096         (changes results)
2097       -> exf_bulkformulae v1.22,
2098          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
2099          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
2100                    output.txt 1.63
2101           offline_exf_seaice: output.seaicetd.txt 1.7
2102           seaice_obcs: output.txt 1.10)
2103      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
2104       -> exf_bulkformulae v1.23,
2105          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
2106          and global_ocean.cs32x15.icedyn (only 11 matching digits)
2107      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
2108    o adjoint of exch-1:
2109     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
2110       (note: was already like this when using EXCH-2) and remove flow dir
2111       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
2112     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
2113     - update pkg/exch2 diff list.
2114    
2115    checkpoint62g (2010/05/19)
2116    o eesupp/src (exch-1):
2117     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
2118       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
2119       (renamed to exch1_*rx_cube.F).
2120     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
2121       to call new exch1 S/R ; update Makefile and .cvsignore.
2122     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
2123       exch2_xy_rx later)
2124      Note: after updating your code, need to run "make clean" in eesupp/src
2125    o test experiment bottom_ctrl_5x5:
2126       new output_adm.txt with fewer grdchk & less monitor output.
2127    o model/src:
2128      remove the call to ini_cori in initialise_varia.F (just keep the usual one
2129       in initialise_fixed.F). More consistent with coriolis & horizontal grid
2130       beeing treated in the same way (ini_grid is not called a 2nd time).
2131    o pkg/exf:
2132      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
2133      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
2134      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
2135      - cosmetic changes to exf_bulkformulae.F to make it look more like
2136        exf_bulk_largeyeager04.F
2137    o eesupp/src (exch-1):
2138      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
2139      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
2140        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
2141        (even without using MPI).
2142      - Message mode: move RecvAck setting (indicator of buffer being ready)
2143        from send_put to recv_get S/R (was useless before, but not sure if
2144        it's much more useful now);
2145      - Switch the order of sync: MPI-proc 1rst and then threads;
2146      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
2147      - fix AD code for communication mode ='get' (but not used).
2148    o model/src:
2149      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
2150      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
2151    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
2152    o pkg/ctrl: require a specific set of control variables and exf-flags for
2153      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
2154    o model/src:
2155     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
2156       1rst forward sweep, to avoid over-writing output files during recomputations
2157       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
2158     b) 2nd version:
2159      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
2160      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
2161         writePickupAtEnd) + seaice & ptracers output;
2162      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
2163    o model/src:
2164      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
2165    o pkg/exch2:
2166      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
2167      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
2168    o pkg/autodiff & exch2:
2169      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
2170      (for now, only if ALLOW_EXCH2 is defined).
2171    o pkg/autodiff:
2172      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
2173        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
2174       + clean-up comments (_RS is not always real*4)
2175      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
2176      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
2177        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
2178    o testreport (AD-tests):
2179      no longer link files from dir "../input" (1rst link files from
2180      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
2181    
2182    checkpoint62f (2010/04/29)
2183    o model/src/the_main_loop.F:
2184      adjust store directives for seaice evp and multicategory according to
2185      pkg/ecco/the_main_loop.F
2186    o adjoint:
2187      global_sum_ad was incomplete (noted many times by many people ;)
2188      nice description by Jean U. as follows:
2189      * allreduce(var) in global_sum.F can be interpreted as
2190        reduce(sum) followed by broadcast of sum.
2191      * The adjoint of that is
2192        sum(adjoint) followed by broadcast(summed adjoint value)
2193        or in other words, allreduce(sum, adjoint vars)
2194      We were missing the sum(adjoint)!
2195      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
2196      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
2197      The fix should produce 16-digit accuracy between
2198      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
2199      multi-CPU single-tile (e.g. nSx=1, nPx-2)
2200      We'll probably change this yet again shortly
2201    o eesupp/src:
2202      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
2203    o pkg/icefront
2204      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
2205        specification of addmass array based on a 2D field, which is added
2206        at bottommost wet level at each horizontal location.
2207    o model/src:
2208     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
2209     layout; (not always compatible with delX,delY setting; commented out for now).
2210    o pkg/exch2:
2211     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
2212     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
2213    
2214    checkpoint62e (2010/04/15)
2215    o pkg/obcs:
2216      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
2217    o pkg/dic:
2218      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
2219        (note: not presently tested in any forward verification exp.)
2220       update tutorial_global_oce_biogeo AD output file.
2221    o pkg/exf:
2222      - account for the variation of albedo as a function of zenith angle
2223        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
2224    o build_options:
2225     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
2226    o pkg/dic:
2227      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
2228      - use binary pickup file for restart;
2229      - initialise atmos-CO2 box from dic_pCO2 parameter;
2230      - fix multi-threaded.
2231    o pkg/rbcs:
2232     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
2233       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
2234     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
2235       and update output.txt
2236    o pkg/kpp:
2237     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
2238     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
2239       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
2240       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
2241     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
2242       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
2243    o pkg/offline:
2244      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
2245      (bug was added in version 1.10 on 2007-08-23).
2246    o pkg/offline:
2247      - no need to specify periodicExternalForcing, etc ... to use offline pack
2248      - offline input files no longer just single prec --> parameter offlineLoadPrec
2249    o verification/lab_sea:
2250      change AD test to multi-tile setup and update all 4 AD output.
2251      NOTE: while cost function values remain very similar,
2252      gradients are very different, although gradient checks are self-consistent
2253      Should try to get to the bottom of this (cost function summation order?)
2254    o pkg/dic:
2255      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
2256      a weakness of TAF that drops part of double precision in log10 derivative.
2257      <= changes removed since problem has been fixed in current TAF version 1.9.71
2258      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
2259    o pkg/ecco:
2260      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
2261      update all 4 lab_sea AD output.
2262    
2263    checkpoint62d (2010/03/22)
2264    o build_options:
2265      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
2266    o remove unbalanced quote (single or double) in commented line of source code
2267      (may cause some warning with some preprocessor/makedepend versions).
2268    o pkg/seaice:
2269      fix seaice_model.F for adjoint (gael) and update AD results of experiments
2270       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
2271    o testreport:
2272      add option '-runonly' (short: '-ro') to just do the run part (without make).
2273    o eesupp: remove JAM communication code (obsolete).
2274    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
2275      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
2276      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
2277      (update also the output).
2278    
2279    checkpoint62c (2010/03/02)
2280    o tools/build_options :
2281       move (some) old optfiles from build_options/ to build_options/unsupported/
2282    o model/src and pkg/exf
2283       surface relaxation -- separating data and data.exf options
2284       The point is to ensure that we specify the surface relaxation
2285       either in data or in data.exf (but not half and half) and to
2286       avoid an accidental relaxation to 0 (which happened if a time
2287       scale was specified but the file name was left empty)
2288    o model/src model/inc and pkg/mom_common
2289       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
2290       => addition to the viscosity field as computed by others schemes
2291    o tools/build_options:
2292      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
2293        but keep the former optfile for few weeks for smooth transition
2294    o pkg/ecco
2295      - allow user defined cost function contributions
2296         CPP: ALLOW_USERCOST_CONTRIBUTION
2297         USAGE: compute contributions in cost_usercost_all.F
2298      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
2299          the two options are complementary.
2300    o pkg/smooth
2301      - migration from contrib to the main repository
2302    
2303    checkpoint62b (2010/01/26)
2304    o pkg/monitor:
2305      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
2306        (in case someone forgot to update customized pieces of code)
2307    o nonHydrostatic:
2308      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
2309      - add a simple 2-D experiment (short_surf_wave) to test it.
2310    o pkg/icefront:
2311       adding the shell of, and the hooks to, a new package that
2312       will model melting and freezing of vertical glacier ice fronts
2313    o momentum:
2314      add diagnostics of momentum tendency from Hydrostatic pressure gradient
2315       (without surf.pressure term: would need a 2nd filling since implicit term).
2316    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
2317      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
2318      cannot deal with the former
2319    o cleaning:
2320      - remove all (except OpenAD) old TLM output from results_ad dirs.
2321      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
2322      - comment out maskH definition (replaced by maskInC)
2323    o pkg/monitor:
2324      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
2325        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.
2326    
2327    checkpoint62a (2010/01/15)
2328    o model/src:
2329      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
2330    o pkg/diagnostics:
2331      - add optional level number diagnostics (i.e., level number to be define
2332        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
2333      - strictly check for valid parser-code(10) ;
2334      - check if adding diag to the list from the right place.
2335    o pkg/longstep:
2336      - change parameters and fix tracer conservation with rstar/nonlinear free surface
2337    o diagnostics:
2338     - in all pkgs, replace remaining calls to old S/R DIAGNOSTICS_ADD2LIST with newer
2339       S/R DIAGNOSTICS_ADDTOLIST ; fix seaice VICE diagnostics.
2340    o pkg/diagnostics:
2341     - Add option for writing vertical integral (sum of selected levels) of an output
2342        field instead of writing output field levels. Activate this option on a per
2343        output-file basis, by setting the 2nd character of fileflag to 'I'.
2344     - Add field-specific information relative to level integral in 3rd postion
2345        of parser diagnostics code (gdiag): " "=cumulate levels, "R"=integrate
2346        vertically (x level-thickness x hFac), "r"=same but without hFac.
2347    o do_the_model_io:
2348      - pass end-of-model-run flag as argument, from forward_step to diagnostics_write:
2349        in case useSIGREG, will write (averaged) diagnostics (if dumpAtLast) before
2350        writing pickups and stopping.
2351    o pkg/diagnostics (for now, only with mdsio):
2352      - write time information to meta file (and modify accordingly rdmds.m) :
2353        time-averaged diagnostics output: write starting and ending time of the
2354        time-averaging interval ; snap-shot diagnostics output remains unchanged;
2355    o pkg/timeave:
2356      - S/R TIMEAVE_NORMALIZ: change size of cumulated-time array (was previously
2357        always Nr), now assumed to be equal to number of levels of averaged field;
2358        only used for DIC_COST monthly mean arrays: this fixes dic_aver_final.F
2359    o pkg/sbo:
2360      - fix ocean bottom pressure global-average & 2-D time-ave output (was
2361        neither initialised nor filled).
2362      - add starting iteration in suffix of global-average output file
2363        (to avoid over-writing the file after a restart)
2364      - use standard MDSIO pkg S/R instead of SBO_WRITEVECTOR (fix byte-swap Pb).
2365    o time-average:
2366      - use simple cumulative-time array (no k index) in all pkgs: {PKG}_timeAve(bi,bj)
2367        (pkgs: aim_v23, bulk_force, dic, gmredi, kpp, land, ocn_compon_interf,
2368         ggl90, my82, opps, pp81, ptracers, sbo, seaice, shelfice, thsice)
2369        this fix DIC_COST cumulative-time array (previously: bi,bj,k)
2370      - fix 1rst call (nIter0) snap-shot output and accumulation (pkg/shelfice)
2371      - fix missing accumulation for pkg/opps.
2372      - cumulate fields only if doing time-ave output ({PKG}_taveFreq > 0)
2373         (pkgs: ptracers, kpp, ocn_compon_interf, ggl90, my82, pp81);
2374      - fix initialisation of time-ave vars and do only full time-step increment
2375        (i.e.: no first & last "half time-step") (pkgs: ggl90, my82, opps, pp81);
2376    o pkg/layers:
2377      - use standard RW pkg S/R to write the output
2378        and remove local write_fld version (which had a problem).
2379      - use simple cumulative-time array (no level index) to fix time-ave S/R calls.
2380      - fix LAYERS_CALC argument list.
2381    o pkg/timeave:
2382      - store cumulative-time in a simple tiled array (drop the level index)
2383      - add new S/R (TIMEAVE_NORMALIZE) which uses simple cumulative-time array.
2384    o pkg/ocn,aim_compon_interf
2385      - changes for multi-threaded coupled run. (tested with ifort-11 on danton)
2386    
2387    checkpoint62  (2009/12/23)
2388    o switch on useOBCSbalance in tutorial_plume_on_slope exp. and update output.
2389        (was not previously tested in any other exp.)
2390    o pkg/monitor:
2391      - clean-up _RL/_RS version: add specific S/R for statistics with mask & volume:
2392        mon_writestats_rl/s,F mon_calc_stats_rl/s.F ; will keep the old one
2393        (mon_printstats_rl/s,F mon_stats_rl/s.F) just for bare statistics.
2394      - use hFac & 2-D mask (instead of 3-D mask + hFac in previous mon_stats_rl.F).
2395      - change del2 calculation.
2396      - use interior masks (instead of maskH, <- to be remove).
2397      - shorter monitor suffix for forcing stats ("forcing" instead of "extforcing").
2398    o mask & obcs:
2399      - define 2-D "interior" masks (i.e., zero beyond OB) at 3 locations (C, W & S).
2400      - move global area computation from ini_masks_etc.F to ini_linear_phisurf.F
2401        (called after packages_init_fixed)
2402    o pkg/obcs:
2403      - move bi,bj loops into obcs_calc, so obcs_prescribe_read is called only once.
2404        Fixes bug in obcs+exf with nSx*nSy.GT.1
2405      - fix multi-tile handling in obcs balance code
2406    o nonHydrostatic:
2407      - Implement AB-3 for non-hydrostatic vertical momentum ;
2408        (change ordering of var. stored in pickup file when using NH)
2409      - move NH code from solve_for_pressure.F to 2 new S/R: PRE_CG3D & POST_CG3D.
2410      - add 2-D field to store Hydrostatic Surface Pressure adjusment from cg3d_x
2411        (in prep. for new NH free surface form).
2412    o pkg/obcs:
2413      add files & OB-variables for wVel (Non-Hydrostatic) with useOBCSprescribe
2414    o model/src:
2415      fix 2-D solver initialisation for deep-atmosphere (p-coord) with topography
2416    
2417    checkpoint61z (2009/12/01)
2418    o nonHydrostatic:
2419      Fix missing vertical flux of vert. momentum near surface (k=1). This fixes
2420        a spurious source of energy in simple baroclinic adjusment test case.
2421      Update all non-hydrostatic exp output.
2422    o model/src (3-d solver):
2423      Change again 3-D solver free-surface RHS term when exactConserv=T:
2424        simpler, consistent with exactConserv, and works with implicDiv2Dflow < 1
2425        (which was not the case with previous formulation).
2426      To recover previous version, just reset "oldFreeSurfTerm" to previous value.
2427      Affects results of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW.
2428    o nonHydrostatic:
2429      - compatible with implicDiv2Dflow < 1 ; + implement implicit factor
2430        for Non-Hydrostatic pressure gradient (similar to implicSurfPress).
2431      - change 3-D solver to work with r* (for now, only with linear free-surf.)
2432      - add few debug diagnostics (cg3d_x, residual)
2433    o model/src:
2434      fix missing EmPmR in 3-D solver RHS (was in cg2d_b but missing in cg3d_b).
2435        update output of exp. global_ocean.cs32x15.viscA4
2436    o update output of exp. global_ocean.cs32x15.icedyn after removing
2437      #define SEAICE_OLD_AND_BAD_DISCRETIZATION from SEAICE_OPTIONS.h
2438    o add entry points for Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
2439    o mnc: add horizontal grid coordinates (XC,YC) and (XG,YG) to netcdf output
2440      for complex grids, for now only to "state", "adstate", "adexf", "adseaice"
2441    o model: add Christopher Wolfe's implemetation of the single reduction cg2d
2442      (d'Azevedo, Eijkhout, and Romine, 1999) with CPP-flag ALLOW_SRCG and
2443      runtime flag useSRCGSolver. Modify verification experiment global_with_exf
2444      to test this code
2445    o pkg/cd_code:
2446      Change defaut D-grid time-stepping to get the same for D-grid momentum as for
2447       C-grid momentum. D-grid velocity used to be stepped forward in time with
2448       Adams-Bashforth only on surface pressure term. Tests show that using AB on
2449       D-grid coriolis term improves stability (as expected from CD-scheme paper).
2450      To reproduce old results, add 2 options (in CD_CODE_OPTIONS.h).
2451      Update results of exp: global_with_exf (x2), ideal_2D_oce, isomip (x2),
2452       lab_sea (3 Fwd +3 AD), natl_box (x2), tutorial_global_oce_biogeo (Fwd+AD),
2453       tutorial_global_oce_latlon, tutorial_global_oce_optim & tutorial_tracer_adjsens.
2454      Keep old results by adding CD_CODE_OPTIONS.h in exp: cfc_example, exp2,
2455           global_ocean.90x40x15(+AD), global_ocean_ebm(+AD) and OpenAD.
2456    o pkg/obcs:
2457     - fix bug in initialisation (broken since Oct 1rst modification)
2458       for useOBCSprescribe without useEXF.
2459    
2460    checkpoint61y (2009/11/15)
2461    o pkg/seaice
2462     - change (once again) the discretization for the evp solver: rather than
2463       squaring the averages of strain rates, average the squares to give
2464       a better approximation to VP behavior (in simple test); this breaks
2465       verification experiments that use EVP (lab_sea and lab_sea.hb87)
2466        --> update outputs
2467    o add CPP-flag (in mom_calc_visc.F) and TAF directive (in gmredi_slope_limit)
2468      to improve vectorization of adjoint code on TARGET_NEC_SX
2469    o verification/vermix:
2470      - change vermix to a more "classical" 1d column with high vertical
2471        resolution, seasonal heat flux forcing and constant wind forcing
2472        --> update outputs
2473    o pkg/seaice
2474     - fix diagnostics of principal stress components for EVP
2475     - add optional diagnostics of non-linear convergence for LSOR solver
2476     - make maximum zeta a runtime parameter
2477    o model/src (3-d solver):
2478      Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49),
2479       which consisted in removing the Surf. Non-Hydrostatic pressure from the
2480       whole column and adding it to Eta (inspired from Casualli, 1999):
2481       Only affects 3-D solver initial guess and only if using ExactConserv,
2482       but tests did show a degradation of solver convergence. For this reason,
2483       decide to disable this piece of code.
2484       to recover previous version, just set zeroPsNH = exactConserv (line 78).
2485      Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW
2486    o pkg/ggl90:
2487     - fix previous modif (unfortunatly has not been documented here).
2488    o pkg/seaice/autodiff:
2489     - add CPP flag to include clipping of zeta in EVP code;
2490       although clipping of zeta is not necessary for EVP and not recommended
2491       it was done by default, now clipping is disabled by default
2492     - modify computation and store zetaC/Z in seaice_evp for TAF
2493     - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
2494     - change seaice_calc_viscosities/strainrates for better
2495       vectorization after AD by TAF
2496     - rearrange common blocks in SEAICE.h once again for easier dumps of
2497       adjoint output, adjust adcommon.h and g_common.h
2498     - change flux form of default advection scheme for better vectorization
2499       of adjoint code
2500     - modify lab_sea/input.lsr to test the flux form of default advection
2501       scheme
2502    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
2503      transition in checkpoint61r)
2504    
2505    checkpoint61x (2009/10/19)
2506    o adjoint: adding two new verification experiments
2507      * tutorial_global_biogeo: an online dic sensitivity experiment
2508        (work with G. Forget)
2509      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
2510        (an update of the Dutkiewicz et al., 2006 paper)
2511      Both use the same CO2FLUX cost function, but different controls
2512      Gradient checks look good, but some recomp. could still be traightened out
2513      Should add xx_dic control variable to test at some point
2514    o model/src:
2515      add run-time parameters to check and/or mask initial Temp & Salt
2516    o pkg/ptracers:
2517      apply zonal filter (if used) to all passive tracers
2518    
2519    checkpoint61w (2009/10/12)
2520    o adjoint:
2521      * update and finish work on adjoint of dic package (G. Forget)
2522      * start adjoint of offline package
2523      * bug fix for cube-sphere TLM code (active_file_g.F)
2524    o tutorial_global_oce_optim:
2525      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
2526      and add SIZE.h_mpi for MPI testing
2527    o pkg autodiff
2528     - fix bug in autodiff_restore
2529     - make genmake2 remove comments and empty lines from ad_input_code.f in
2530       order to reduce file size (new script file remove_comments_sed)
2531    o allows to specify vertical profile of vertical viscosity (viscArNr)
2532    o pkg autodiff
2533      autodiff_ini_model_io: comment out writing of grid information to netcdf
2534      files, because at this time the grid fields are a bunch of zeros
2535      (this is analogous to ini_mnc_vars.F)
2536    o pkg seaice/autodiff:
2537     left-over from removing the 3-time-level fields:
2538     - small rearrangement of common blocks (SEAICE.h)
2539     - fix field declaration in order to get meaningful output in
2540       adseaice.*.nc (adcommon.h)
2541    o pkg obcs:
2542     - go through NH code only if nonHydrostatic=T
2543     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
2544     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
2545       => Update output of experiment seaice_obcs
2546     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
2547     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
2548     - fix restart for useOBCSprescribe + useEXF
2549    o pkg ctrl
2550     - make obcs as control parameter work also with useSingleCPUio
2551     - replace a few sny and snx by Ny and Nx to be consistent with
2552       ctrl_set_globfld_x/yz.F
2553    o pkg seaice
2554     - re-introduce global field frWtrAtm for the case of
2555       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
2556     - catch the case of an empty filename in seaice_cost_init_fixed.F
2557    o pkg ecco:
2558     - small bug fixes in the_main_loop
2559      . fix order of monitor arguments
2560      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
2561      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
2562        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
2563     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
2564       imbalance diagnostics for wmean_h/sflux = 0
2565     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
2566     - catch the case of empty filenames in ecco_cost_init_fixed.F
2567       and ecco_readparms.F
2568     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
2569       to make this statement meaningfull in ecco_cost_weights.F
2570    o pkg zonal_filt:
2571      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
2572      - when using rStar, filter uVel*hFacW instead of uVel
2573       (tested without topography: fix a Pb of growing instability with NLFS)
2574    o pkg/aim/thsice:
2575     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
2576      (works as SST restoring)
2577    o pkg/thsice:
2578     -add specific parameter for salt restoring in slab mixed-layer
2579       (by default equal to the temperature restoring)
2580    
2581    checkpoint61v (2009/09/21)
2582    o pkg/kpp:
2583     -add double diffusive contributions as a hack, turned off by default
2584      for now, and the code can be excluded with a CPP-flag
2585      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
2586     -add a verification experiments to "vermix" to test this code
2587    o pkg/mom_common:
2588      Move computation of length scales to mom_init_fixed.F (avoid recomputation
2589      at each time-steps*levels).
2590    o pkg/layers:
2591      Created a new package for computing volume fluxes in temperature or
2592      [not yet implemented] density layers, e.g. for calculating residual
2593      overturning circulations.
2594    o pkg/diagnostics:
2595      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
2596    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
2597    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
2598      To avoid mixing type (RS/RL) of input/output array argument,
2599      replace single mixed-type array with a pair from each type (RS/RL).
2600    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
2601      is now implemented for all pkgs (previously only done for the main pickup)
2602    
2603    checkpoint61u (2009/08/25)
2604    o pkg/obcs:
2605      - change OB?eta from _RS to _RL and put them into a separate commen block
2606      - add code to read OB?eta from a file via obcs_prescribe_read: the code
2607        compiles and does not destroy any other experiments, the data is read
2608        properly, but the code is not tested in actual applications
2609    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
2610      create a meaningful unit attribute for the time coordinate variable
2611    o pkg/ebm: add plenty of missing "_d 0" ;
2612       update results of experiment global_ocean_ebm (fwd + adjoint tests)
2613      Notes: several pieces of code only works for (very) specific set up
2614       (domain size, lat range, etc ...); should be documented & stop if one
2615       of those assumptions is not meet.
2616    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
2617       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
2618          and offline_exf_seaice (seaicetd + adjoint).
2619    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
2620       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
2621        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
2622    o few changes to pass when compiling with strick checking of arguments
2623       across S/R (allow to find few bugs in S/R calls).
2624    o pkg/seaice:
2625     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
2626       2d-fields, for slightly better performance
2627    
2628    checkpoint61t (2009/07/22)
2629    o pkg/seaice:
2630     - remove unused variables in seaice_evp
2631     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
2632    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
2633       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
2634       each processor opens a different file (a fix from Matt).
2635    o cg2d:
2636       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
2637       this reduces number of EXCH calls by 2 when using exch2.
2638       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
2639       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
2640    o pkg/thsice:
2641       add code for Near Infra-Red albedo (from Jeff)
2642       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
2643    o ini_model_io:
2644       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
2645       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
2646       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
2647    
2648    checkpoint61s (2009/06/30)
2649    o pkg/exch2 (exch2_rxN_cube*):
2650       remove last BARRIER (no need to synchronise after getting data from shared
2651       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
2652    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
2653      and generate new output (for the 2 tests) using default rotationPeriod.
2654    o pkg/exch2:
2655      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
2656        (was already the case with AUTODIFF_EXCH2 defined)
2657      - add bj in exch2 arrays and S/R.
2658      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
2659        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
2660    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
2661      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
2662        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
2663      - verification experiment natl_box.longstep
2664    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
2665      allow different versions of ifort (8 or 9) and different versions
2666       of mpi (mpich or mpich2) to be used with the same optfile.
2667      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
2668       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
2669    o pkg/seaice:
2670      fix previous modif (3-level field removed) for old-pickup reading
2671    
2672    checkpoint61r (2009/06/25)
2673    o pkg/seaice:
2674     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
2675      1. introduce fields for time step (N-1)
2676      2. do not use levels 2 and 3 anymore (but keep them)
2677      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
2678         includes changes to pkg/thsice/thsice_get_velocity.F,
2679         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
2680         pkg/obcs/obcs_apply_uvice.F.
2681     - completely remove code for leap-frog time stepping for second order
2682       advection
2683     - adjusted adjoint accordingly;
2684       gradient checks have improved by an order of magnitude!
2685    
2686    checkpoint61q (2009/06/22)
2687    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
2688     - the boundary conditions along open boundaries are unclear, because the
2689       associated masks are set to zero and are thus treated as closed when
2690       applying the slip-boundary conditions.
2691     - move initialisation of grid variables from seaice_init_varia to _fixed
2692    o adding doc/diags_changes.txt
2693    o model/src:
2694      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
2695       to avoid "_diags" naming if no relation to pkg/diagnostics.
2696      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
2697       file and only call PLOT_FIELD_XYZ if debugMode=T.
2698      remove few PLOT_FIELD_XY calls outside initialisation.
2699      remove few unnecessary BARRIER.
2700    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
2701      of salt_plume package in Southern Ocean
2702    o pkg/thsice:
2703     - fix hOceMxL in overlap (needed for sea-ice advection);
2704       update output of experiment global_ocean.cs32x15.icedyn.
2705    o pkg/seaice:
2706     - make the (placeholder-)tracer IceAge a little more meaningful
2707      by avoiding ridging of age due to convergent ice flow
2708     - add diagnostics for surface temperature, atmospheric and oceanic
2709       heat flux, and atmospheric and oceanic ice growth
2710    
2711    checkpoint61p (2009/06/10)
2712    o eesupp (global_max & global_sum):
2713     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
2714     - remove starting & endding barrier (no longer needed)
2715    o pkg/mdsio, writelocal:
2716       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
2717       (remove the STOP): uses shared buffer IO to store data from all threads
2718       and then let master-thread write nThreads tiles.
2719    o pkg/mdsio (read/write field):
2720     - tiled IO done in 1 piece (all levels at a time);
2721     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
2722     - multi-threaded: allow to read/write local (non-shared) array
2723       (was already working with singleCpuIO ; now works also without);
2724       => no longer needs barrier call after reading a file (added inside
2725       mds_read/write field).
2726     - move barrier calls outside gather/scatter_2d to mds_read/write_field
2727    o pkg/obcs/exf
2728      - exf_getffieldrec.F: add a few ". _d 0" and
2729                            add code to catch the case fldperiod = 0.  
2730      - obcs_precribe_read.F: change if statements so that they match
2731                              the variable type (_RL)
2732      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
2733        exf_iprec) as part of namelist EXF_NML_01
2734    o pkg/mdsio:
2735      - read/write tiled (local) files: read/write 1-level tile chunk at a time
2736        (instead of segment of length sNx); expected to speed up tiled IO.
2737    o pkg/exch2:
2738      - take buffer copy from/to array out of S/R exch2_send/recv into new
2739        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
2740        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
2741      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
2742      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
2743        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
2744        including Topology header file (and common blocks).
2745      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
2746        remove 2nd exch call in exch2_s3d_rx (no longer needed).
2747      - document S/R arg. list (+ update some comments)
2748    o pkg/seaice:
2749      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
2750        temperature and humidity over sea ice based on climatological values.
2751      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
2752        of LSR (this change is expected to change the results slightly because now
2753        it uses slightly difference moduli from the second last LSR solution, but
2754        that is more consistent with the stress computations; this part of the code
2755        is not tested in the verification experiments)
2756      - fix diagnostics for flux of ice in case of B-grid
2757      - turn strain rates eij and press into global fields within global
2758        common block in SEAICE.h for more straighforward diagnostics
2759      - fix diagnostics for principal stress components, press, zeta, eta
2760        to give something meaning full
2761    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
2762      new output (all 4 tests) using default rotationPeriod.
2763    o pkg KPP:
2764      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
2765      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
2766        and normal grid from 1 to Nr)
2767    o Fix computations of L4rdt in mom_calc_visc.F
2768    o eesupp:
2769      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
2770      should be called before a "stop" if we know that all process are going
2771      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
2772    
2773    checkpoint61o (2009/05/26)
2774    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
2775    o model/src/ini_curvilinear_grid.F:
2776       compute angleSin/CosC when they are not read from a file
2777    o pkg/seaice:
2778       add pseudo time stepping for LSOR
2779    o pkg/exch2:
2780       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
2781    o pkg/seaice:
2782       Adding separate sea ice albedo, drag coefficients, and HO in Southern
2783       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
2784    o SingleCpuIO:
2785       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
2786    o pkg/seaice:
2787       put exchanged variable in (local) common block for MPI+Multi-Threads
2788       to work (necessary with exch1, and for now with exch2 too).
2789    o verification: to get more experiments tested with mpi, mth and mpi+mth,
2790      change tiling of:
2791       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
2792       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
2793      update output of exp:
2794       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
2795       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
2796      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
2797                       (note: output.txt generated on faulks using only 1 tile)
2798    o eesupp & mdsio (SingleCpuIO):
2799     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
2800       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
2801       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
2802     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
2803     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
2804       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
2805    o pkg/exch2:
2806     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
2807       read parameter file "data.exch2" if it exists; otherwise try default regular
2808       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
2809     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
2810       with new code (not to be used, just as a backup solution).
2811     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
2812       in utils/exch2/input.
2813    
2814    checkpoint61n (2009/05/12)
2815    o eesupp & mdsio (SingleCpuIO):
2816      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
2817        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
2818        receive real*4 array (instead of real*8) to read/write 32.bit files.
2819        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
2820         and remove new mapping S/R)
2821    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
2822      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
2823        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
2824        when using exch2. Add S/R to map global io-buffer to global model array.
2825      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
2826    
2827    checkpoint61m (2009/04/29)
2828    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
2829      and add 3 other S/R for other types (R4,R8,RS).
2830      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
2831    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
2832     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
2833     - reduce number of macro definitions (keep only those which are used);
2834       can always call directly the corrresponding S/R if needed.
2835     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
2836       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
2837     Fixed wrong type of arg in:
2838       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
2839       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
2840     To fix: global_sum of var in common block is wrong (multi-threaded) in:
2841       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
2842     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
2843    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
2844      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
2845    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
2846    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
2847      edges are closed (zero depth); might happen with "blank tiles";
2848      for now, disabled if using OBCS.
2849    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
2850      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
2851    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
2852      to reduce length of 1.D array print in STDOUT.
2853    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
2854      + use 48 tiles (16x8): this will allow to test "blank tiles".
2855    o start to test MPI + multi-threaded (change testreport to skip tests
2856      where number of tiles do not match).
2857    o genmake2: add option "-omp" to turn on Open-MP ;
2858      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
2859    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
2860      and keep the original tile numbering. Note: compatible with old
2861      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
2862    
2863    checkpoint61l (2009/04/07)
2864    o Overlaps had been forgotten in calculating ijk keys : fixed
2865    o fix cyrus makedepend for gcc 4.4
2866    o experiment fizhi-cs-aqualev20:
2867      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
2868      and generate new output. Note: new output is much closer to the old
2869      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
2870      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
2871    o pkg/fizhi:
2872     - change to avoid indices going deliberately over array-bounds
2873     - remove unnecessary MPI stuff
2874     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
2875     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
2876       does not go over array-bounds and therefore returns reliable output.
2877     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
2878       this S/R has 4 output arguments, which are used inside "get_alarm";
2879       when it is called with the same variable "ndum" in place of several
2880       output arguments, this produces weird side effect inside "get_alarm"
2881      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
2882       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
2883       address) and produces error.
2884    o tools/gemake2: (March 27-29 2009)
2885      with option "-mpi": link *_mpi files from "MODS" dir (this is what
2886      testreport does).
2887    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
2888    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
2889       update lab_sea.lsr & lab_sea.salt_plume results
2890    o pkg/seaice:
2891      Major overhaul of the LSOR solver: change discretization from original
2892      finite differences to finite volume. The old routine is still in the
2893      file seaice_lsr.F and can be turned on with the CPP-flag
2894      SEAICE_OLD_AND_BAD_DISCRETIZATION
2895      Along with this change, the discretization of the strain rates is changed.
2896      The same flag turns on the old discretization in seaice_calc_strainrates.F
2897      All verification experiments with seaice are affected (except for
2898      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
2899      results by setting the above flag.
2900      Further changes involve changes in defaults:
2901      - ALLOW_FLOODING is defined and turned on by default
2902      - SEAICEadvSnow = .true. is now the default
2903      - SEAICEadvSalt = .true. is now the default
2904      - SEAICEadvAge  = .true. is now the default
2905      - SEAICE_clipVelocities  = .false. is now the default
2906                                         (as per J. Zhang's recommendation)
2907      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
2908        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
2909      - seaice_growth: replace computation of UG by a simple copy from wspeed
2910    
2911    checkpoint61k (2009/03/18)
2912    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
2913      seaice_lsr: fixed a few metric terms,
2914                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
2915                  add more debugging diagnostics
2916      seaice_evp: removed superfluous many metric terms of FV discretization
2917                  of stress divergence
2918                  affects lab_sea, lab_sea.hb87
2919      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
2920                  of stress divergence for non-evp solver
2921                  (this part is not tested anywhere)
2922      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
2923                  they were effectively only half slip
2924                  affects lab_sea.hb87
2925      updated all relevant verification experiments (except lab_sea//output_adm.txt
2926        which was left over, but fails at level 7 & 6)
2927    
2928    checkpoint61j (2009/03/17)
2929    o pkg/seaice: turn a few hard wired parameters into run time parameters
2930    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
2931      time in seconds as promised by the usints in seaice_monitor and exf_monitor
2932    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
2933      that are not cubed-sphere grids
2934    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
2935    o pkg/ctrl:
2936      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
2937    o non-hydrostatic (calc_gw.F):
2938      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
2939      update output of exp. global_ocean.cs32x15.viscA4
2940    o remove backward compatibility for thetaMin,phiMin
2941      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
2942    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
2943      interpolated wind field not only for curvilineargrid=.true., but also
2944      for a rotated grid (rotateGrid=.true.)
2945    o pkg/exf: add capability to bypass interpolation for runoff
2946      by setting yet another CPP-flag
2947    o eesupp/src, B-grid exchange:
2948      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
2949    o autodiff
2950      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
2951      allows to switch to single-prec common blocks;
2952      corresponding switch occurs in tamc.h, integer isbyte
2953      TAF store directivs "byte" and "kind" seem equivalent;
2954      Most tamc.h have been updated correspondingly.
2955    
2956    checkpoint61i (2009/02/13)
2957    o autodiff:
2958      fix autodiff_sore/_restore indices for obcs
2959      (spotted by I. Hoteit, M. Mazloff)
2960    o pkg/autodiff, pkg/ctrl:
2961      Add flag to reduce all tapelev I/O to single-prec.
2962      In data.ctrl set
2963        doSinglePrecTapelev = .TRUE.
2964    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
2965      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
2966    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
2967      real fresh water flux (not yet)
2968    o pkg/mdsio & rw:
2969     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
2970     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
2971    o pkg/flt:
2972     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
2973       init_fixed & ini_varia.
2974     - clean-up & simplify linear interpolation S/R:
2975       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
2976     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
2977     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
2978     - add vert. coordinate & horiz. indices to output files.
2979     - change vertical position in initial condition, from index to depth [m].
2980     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
2981       (easier to get to a curvilinear grid) ; delX,delY no longer used.
2982    o pkg/ggl90: a few modifications:
2983     - fix bottom boundary condition, and interpolation of KappaE
2984       near top and bottom
2985     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
2986     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
2987     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
2988    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
2989      (maintain temporary backward compatibility, until next checkpoint)
2990    
2991    checkpoint61h (2009/01/27)
2992    o pkg/diagnostics with "periodic averaging diagnostics":
2993      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
2994    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
2995    o pkg/obcs: fix loop ranges for balancing code
2996    o pkg/flt:
2997     - improve criteria for finding which tile owns a float.
2998     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
2999    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
3000      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
3001      with ocean biogeo)
3002    o pkg/flt:
3003     - do some cleaning and fix the restart ;
3004     - add output.txt in flt_example/results to get this pkg tested.
3005    o genmake2: add an EXTENDED_SRC option and flag.
3006       for now, cannot be turned on on command line (only through genmake_local)
3007    o pkg/mdsio: read/write vector:
3008     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
3009     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
3010       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
3011     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
3012      (drop to 4 digits matching for grad). But this test does not look very
3013      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
3014    
3015    checkpoint61g (2008/12/29)
3016    o pkg/flt:
3017      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
3018       + make OPTIONS file more standard.
3019      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
3020      - fix _BYTESWAPIO CPP-Flag
3021      - standard reading of file-parameter "data.flt"
3022      - fix argument list of S/R FLT_RESTART
3023      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
3024    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
3025    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
3026      a still unfixed compiler/optimization bug
3027    
3028    checkpoint61f (2008/11/21)
3029    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
3030      update results of global_ocean.cs32x15.icedyn test.
3031    o move getcon.F from model/src to pkg/fizhi.
3032    o pkg/exf: add parameter for extrapolation of temp up to the surface
3033       and option to prevent negative evap (in bulk_largeyeager04 only).
3034    o Prather Advection scheme: fix tracer conservation for divergent flow
3035      (e.g., when using NonLin Free-Surface).
3036    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
3037    o gmredi (Visbeck-variable-K):
3038     - add more parameters to Visbeck-variable-K.
3039     - use a 5 points average for dSigmaR in Visbeck-K calculation
3040       (more "homogenous": same stencil and same weights as in dSigmaH)
3041     - update output of ideal_2D_oce experiment.
3042    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
3043      (#undef REAL4_IS_SLOW)
3044     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
3045       coordinate variable
3046     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
3047       (surface forcing fields), removes some of the functionality
3048     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
3049     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
3050       probably not all: copy _RS surface flux fields to RL field before
3051       calling DIAGNOSTICS_FILL
3052     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
3053       real*4 (CALL EXCH_*_RS) versions.
3054     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
3055       (generate new output).
3056    
3057    checkpoint61e (2008/10/23)
3058    o gmredi (Visbeck-variable-K):
3059      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
3060      - change computation of Visbeck-K where Slope > Smax :        
3061        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
3062        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
3063    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
3064      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
3065    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
3066    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
3067      does not become too large (to avoid precision problems in implicit-diffusion
3068      solver); update ideal_2D_oce output.
3069    o pkg ggl90:
3070      - in ggl90_cal.F: compute only one set of visc/diff, used to
3071        step forward TKE/T/S/momentum
3072      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
3073        have Prandlt =1)
3074    o gmredi (fm07):
3075      - add lower limit on Transition layer thickness + lower limit on 1/lambda
3076      - allow to set few more params from data.gmredi
3077    o pkg ggl90:
3078          - add missing sqrt(2) factor in computation of mixing length
3079            scale in ggl90_calc.F
3080            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
3081    
3082    checkpoint61d (2008/09/25)
3083    o adjoint modifs
3084      - adapt to new field rhoInSitu
3085      - allow to revert from StoreDynVars2D, StoreDynVars3D
3086        to individual fields
3087        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
3088    o store 3-D (in-situ) density in commom block (DYNVARS.h)
3089     - save 1 rho computation.
3090     - no longer modify T & S inland when using down_slope pkg.
3091    o gad_som : allow to switch to SOM advection for T & S without corresponding
3092      pickup files (using new S/R: MDS_CHECK4FILE).
3093    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
3094      (for useSingleCpuIO to work in multi-threaded)
3095    o pkg/shelfice:
3096     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
3097       with SHELFICEtopoFile in data.shelfice
3098     - move code for reading ice shelf topography and modifying hFacC into separate
3099       subroutines of the shelfice package
3100     - separate initialisation of "fixed" and "variable" variables
3101     - kTopC is not (yet) replaced by kSurfC, although this is possible
3102    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
3103    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
3104      and rename:
3105      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
3106      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
3107    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
3108    
3109    checkpoint61c (2008/08/30)
3110    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
3111      to add mass source/sink of fluid in the interior (3-D generalisation
3112      of oceanic real-fresh water flux).
3113    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
3114    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
3115    o new pkg: down_slope
3116      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
3117      - presently, modify T & S inland (dwnslp_calc_rho.F).
3118        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
3119      - implementation for ocean in P-coords not tested.
3120      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
3121    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
3122      (to facilitate conversion of oceanic pkg to p-coordinate).
3123    o change FIND_RHO to FIND_RHO_2D :
3124      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
3125    o new pkg: cheapaml
3126    
3127    checkpoint61b (2008/08/05)
3128    o exch2:
3129      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
3130      - no longer depend on the order sequence (N,S,E,W).
3131      - 3rd exchange no longer needed (tested with 24 tiles).
3132      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
3133      - exch_UV_A-grid readily available (but not yet tested).
3134      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
3135      (both are no longer needed) in exch_uv: no effect in forward run; but
3136       get truncation error differences with adjoint exch.
3137    o exch2:
3138     - change index-bounds storage (moved from target to local tile,
3139       more intuitive this way) ; rename/remove some variables.
3140     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
3141    
3142    checkpoint61a (2008/07/29)
3143    o exch2/matlab-topology-generator:
3144      fix bug in index bounds for N-S internal exchange (hard to tell if this
3145      had any effect on the solution).
3146    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
3147      is exceeded
3148    o testreport: modify syntax of awk, so that it works also with
3149      awk, and not only with nawk and gawk
3150    
3151    checkpoint61 (2008/06/24)
3152    o autodiff
3153      Change default for TAF usage by removing argument '-nonew_arg'
3154      This changes TAF subroutine argument list (ordering of active var.)
3155      Omission of this flag leads to incompatibility w.r.t. TAMC
3156      To restore TAMC-compatibility, need following modifs:
3157      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
3158      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
3159      Tested TAF version is 1.9.22
3160      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
3161    
3162    checkpoint60 (2008/06/19)
3163    --->>> This is the last checkpoint for which generating the adjoint
3164    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
3165    --->>> by default.
3166    --->>> Future checkpoints will ommit this flag by default.
3167    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
3168    o pkg/grdchk: Add gradient check to etan0 perturbations.
3169    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
3170    o pkg/autodiff: more flexibility in zeroadj.
3171      model/src: modifying do_oceanic_phys.F accordingly.
3172    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
3173    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
3174      special setup of gmredi for which the adjoint is stable
3175      enough for parameter optimization.
3176    o bridging the gap between eddy stress and GM.
3177      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
3178          along with a change in CPP option (now ALLOW_EDDYPSI).
3179      -> when using GM w/ GM_AdvForm:
3180          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
3181          is applied either in the tracer Eq. or in momentum Eq.
3182          depending on data.gmredi (intro. GM_InMomAsStress).
3183      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
3184      The key modifications are in model/src/taueddy_external_forcing.F
3185      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
3186    
3187    checkpoint59r (2008/05/29)
3188    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
3189      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
3190      fix option to read coriolis(@ cell-corner) from files with CS-grid.
3191    o pkg/mnc: add some attributes to standard 1D-coordinate variables
3192    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
3193      mass points, when using mnc for output
3194      - add runtime parameter (missing_value, missing_value_int) to override
3195        default (which is the value of getcon('UNDEF'))
3196    o pkg/mnc: prepare mnc for the actual use of missing values with the
3197      diagnostics package: small fix in mnc_cw_readwrite.template and more
3198      initialisation of never used fields
3199      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
3200      versions
3201    o pkg/thsice/thsice_ini_vars.F added default initial values so that
3202      thermodynamics sea ice solver does not blow up when some initial fields
3203      are missing.
3204    o move from external_forcing_surf.F to ini_forcing.F
3205      the p-coord. hack consisting in using pLoad to set phi0surf ;
3206      update output of tutorial_global_oce_in_p (affected @ truncation level).
3207    o Freshen up a bit hs94.1x64x5, notably:
3208      remove rotationPeriod and tRef=5*0. (adjoint only), and add
3209      exactConserv=.TRUE.
3210    o pkg/generic_advdiff:
3211      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
3212      applies to files where Temperature & Salinity 2nd Order moments are used.
3213    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
3214      this uses a dynamically allocated internal state data structure
3215      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
3216      and requires a fortran 90 compiler
3217    
3218    checkpoint59q (2008/05/06)
3219    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
3220       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
3221    o Refresh tutorial_global_oce_biogeo, notably:
3222      - change bathymetry (put back seamounts in ACC, use hFacs)
3223      - change EOS (POLY3 --> JMD95Z)
3224      - use Bryan-Lewis vertical diffusivity
3225      - use multidimensional advection
3226      - remove old virtual virtual in dic pkg, now done through ptracer pkg
3227      - change a couple of parameters in dic pkg
3228    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
3229    o pkg/obcs: change default to OBCSfixTopo = .true.,
3230      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
3231      - replace "debugMode" with "debugLevel .GE. debLevB"
3232    o implementation of TAF directives for gchem,cfc,dic
3233    o remove "exp5" (replaced by tutorial_deep_convection).
3234    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
3235      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
3236      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
3237      --> changes results in exp4, seaice_obcs
3238    o tutorial_deep_convection :
3239      update the set-up and increase resolution and domain size ; start
3240      from pseudo initial conditions = output at t=120mn in order to see
3241      something happening when running testreport.
3242    o pkg/seaice: add os7mp as an advection scheme
3243                  add check for advection schemes
3244                  add a flag for restoring T and S underneath sea ice
3245    o pkg/my82: add netcdf-support and diagnostics
3246    o thsice pkg:
3247      - Now hsMax limits snow height by turning it into ice following
3248        flooding scheme (and now conserving energy)
3249      - Slight rewriting of the formula in thsice_calc_thick.F
3250      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
3251      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
3252    
3253    checkpoint59p (2008/04/10)
3254    o gchem / dic / cfc :
3255      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
3256      - add new parameter files: "data.dic" & "data.cfc" ;
3257      - various re-arrangement in initialisation & header file ;
3258      - fix tutorial_global_oce_biogeo for multi-threaded test.
3259    o pkg/dic: test for "pickup_dic" file when restarting ;
3260      if no pickup-file, can restart with a re-initialised pH (same as it did
3261      before) providing pickupStrictlyMatch is set to False.
3262    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
3263      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
3264    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
3265      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
3266    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
3267     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
3268       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
3269    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
3270       scheme to use for vorticty-term ;
3271     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
3272       (with default selectVortScheme, return to original discretisation)
3273     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
3274    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
3275    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
3276      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
3277      also fix diagnostics VISCAHW & VISCA4W.
3278    
3279    checkpoint59o (2008/03/07)
3280    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
3281    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
3282      move a few statemens out the main loop into separate loops
3283    o pkg/shelfice:
3284      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
3285        (kg/m^2/s), does not break tests, because in verification/isomip,
3286        rhoConstFresh=rhoConst (by accident)
3287      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
3288      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
3289        new file model/src/seawater.F, so that they are available for all pkgs.
3290      - convert potential temperature into in-situ temperature. This changes the
3291        isomip tests => update tests
3292    o add a flag writePickupAtEnd (default=true) to be able to suppress
3293      writing a pickup at the last timestep
3294    o tools/mpack-1.6 :
3295      - disable automake (not working) and autoconf (not needed).
3296      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
3297        also cleaner with much less compilation warnings.
3298    o pkg/profiles:
3299      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
3300      (for "less than 32 characters name" compiler requirement)
3301    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
3302      conditions that have a different sampling frequency than S/T/U/V obcs
3303    o pkg/diagnostics (stats-diags):
3304      - fix global Min/Max in case 1 processor get only empty tiles
3305    o genmake2: replace (4 times)
3306         make genmake_tc_1.o >> genmake_warnings 2>&1
3307      with
3308         COMM="$CC $CFLAGS -c genmake_tc_1.c"
3309         echo $COMM >> genmake_warnings
3310         $COMM >> genmake_warnings 2>&1
3311      to make genmake2 always see the value of CC as specified in the optfile.
3312    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
3313      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
3314      - modify verification advect_cs test to test SOM-advection on CS-grid.
3315    o pkg/ctrl:
3316      - Rewrite of ctrl_map_ini_ecco.F,
3317        introducing a generic routine (ctrl_map_ini_gen.F).
3318      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
3319    
3320    checkpoint59n (2008/02/09)
3321    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
3322      number in dedicate array "hdiag":
3323      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
3324        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
3325      - many small changes (integer format) for large number of diagnostics
3326      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
3327        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
3328    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
3329      usingSphericalGrid, this allows to define the rotated grid coordinates
3330      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
3331      geographical coordinates according to the inverse of the rotation defined
3332      by the Euler angles, so that Coriolis parameter and online-interpolation by
3333      exf works with the geographical coordinates on XC/YC/XG/YG.
3334      Naturally, this feature does not work with all packages, so some
3335      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
3336      profiles), because there the coordinates are assumed to be regular
3337      spherical grid coordinates.
3338    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
3339      - introduce isopycnal diffusion coefficient control.
3340    o tools/adjoint_options:
3341      - additional control vector components.
3342    o pkg/mnc: have mnc create marginally meaning full coordinate variables
3343      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
3344    o pkg/mypackage:
3345      - add example of read/write pickup for state-var ;
3346      - add entry points to the main code for state-vars diags & write-pickup.
3347    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
3348      transitions for useExfYearlyFields
3349      - add new subroutine that determines the file to read from for
3350        use*YearlyFields = .TRUE. and .FALSE.
3351      - add a verification experiment to global_with_exf that tests
3352        useExfYearlyFields with USE_EXF_INTERPOLATION defined
3353    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
3354      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
3355      subroutines (which could be generated from a template, because they are
3356      almost identical), for now they are included in obcs_prescribe_read.F for
3357      simplicity
3358    o pkg/exf:
3359      - add a little more diagnostic to exf_interp_read (in analogy to
3360        mds_read_field, can be turned off with debugLevel < debugLevA=1)
3361      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
3362        ugly but fast by unrolling short inner loops, inserting a unroll=8
3363        directive in routine lagran, and splitting a loop and making do while the
3364        outermost loop (the latter requires the intoduction of index arrays)
3365    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
3366    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
3367      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
3368    o verification/seaice_obcs: updated for restart test and latest options
3369    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
3370      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
3371      for now this is only available for the C-grid code and also within
3372      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
3373    
3374    checkpoint59m (2008/01/14)
3375    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
3376      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
3377    o gad_som : fix flux output (& diagnostics) to have same units as other  
3378      advection scheme fluxes (was previously multiplied by deltaT).  
3379    o added verification/seaice_obcs both to test seaice open boundaries
3380      and to provide an example matlab scrpt for generating them
3381    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
3382    o pkg/salt_plume: clean up salt_plume_frac.F to
3383      remove redundancy in PlumeMethod 1 and 4
3384    o pkg/kpp: added saltplume diagnostics
3385    o pkg/obcs and pkg/seaice:
3386      - do not set uice and vice to zero when OB*icefile are unspecified
3387      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
3388      - moved seaice tracer obcs after call to seaice_growth
3389    o pkg/salt_plume: added various options for salt plume depth
3390      criterion and for vertical distribution of the salt
3391    
3392    checkpoint59l (2007/12/18)
3393    o pkg/ptracers: new version of ptracers pickup:
3394      read meta file and write only fields which are needed to restart.
3395      ( same logic as main pickup file ; also using pickupStrictlyMatch )
3396    o pkg/seaice:
3397      - add timescale for melting due to warm mixed layer as a means of
3398        setting SEAICE_availHeatFrac more conveniently
3399      - add a CPP-flag/runtime parameter check for flooding algorithm
3400      - reformulated availHeat in seaice_growth.F to be independent of AREA
3401    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
3402      unit changes
3403    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
3404    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
3405      SX vector computer.
3406    o pkg/seaice:
3407      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
3408        seaice forcing fields can now be read only through pkg/exf
3409      - removed some unused halos
3410    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
3411    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
3412      or U/VICE from U/VWIND before computing U/VSTRESS
3413    
3414    checkpoint59k (2007/11/30)
3415    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
3416      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
3417    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
3418      all experiments pass when compile with un-initialised var. checking option.
3419    o added pkg/salt_plume
3420    o script to test restart (for now, in MITgcm_contrib/jmc_script)
3421    o pkg/seaice: new read/write pickup version.
3422      read meta file and write only fields which are needed to restart.
3423      ( same logic as main pickup file ; also using pickupStrictlyMatch )
3424    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
3425    o lab_sea.hb87: modify the domain & update output.hb87.txt :
3426      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
3427      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
3428      process. Fixed here by closing the domain at the Northern boundary.
3429    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
3430    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
3431      a set of consecutive levels in/from a 3-D array.
3432    o pkg/ptracers:
3433      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
3434      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
3435    
3436    checkpoint59j (2007/11/09)
3437    o in pkgs: dic, obcs, offline, rbcs:
3438      standard way to compute coeff. for time interpolation between 2 time reccords
3439      which retains full precision (& make results less dependent on compiler).
3440      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
3441    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
3442      packages instead of reading ice cover and wind speed separately
3443    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
3444     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
3445      to allow to compile customized code before the update)
3446    o cleaning-up:
3447      - fix CPP instruction syntax in pkg/obcs
3448      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
3449        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
3450      - fix some threads issue in IO parts.
3451    o pkg/dic:
3452      - add tons of "_d 0" (--> much better testreports !)
3453       and then update outputs of tutorial_global_oce_biogeo
3454    o pkg/mom_fluxform:
3455      add a special version of momentum advection intended to conserve momentum
3456      next to a bathymetry step or a coastline edge. (default = off = #undef)
3457    o new read/write pickup version:
3458      - for now, only implemented for main (mdsio) pickup file.
3459      - write out only what is needed to restart; merge pickup_nh , pickup_ph
3460        and main pickup together.
3461      - read meta file; read only what is needed to restart; stop if a field
3462        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
3463        if it make sense (even if the restart is not perfect).
3464      - if no meta file, assume that pickup to read corresponds exactly to
3465        a pickup that would currently be written.
3466      - read pickup written in the old format (until checkpoint59i) if it
3467        recognizes an old meta file (no field-list).
3468      - add a meta file in exp. which starts from a pickup: 2 cases:
3469        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
3470         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
3471        b) a meta file describing the content of the associated pickup file
3472         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
3473    o pkg/mdsio & pkg/rw:
3474      - new routine to read a meta file ; new set of routine to read
3475        Multiple-fields file (with meta file).
3476    o added open boundary conditions capability for seaice
3477        HSNOW, HSALT, UICE, and VICE
3478    
3479    checkpoint59i (2007/10/21)
3480    o adjoint:
3481      * fix multiDimAdvection adjoint
3482        (partial recomputation problem by TAF for fVerT(:,:,kDown)
3483        and comlev1 size definition (maxpass vs. max. number of tracers)
3484      * verification/global_ocean.90x45x15 adjoint now tests
3485        NLFS and multiDimAdvection using DST3 (=30)
3486      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
3487    o pkg/kpp: add "_d 0" to real constant (if missing);
3488      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
3489      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
3490    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
3491      for internal parameters related to restart process (formerly from PARAMS.h)
3492      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
3493    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
3494      as argument. (only atm2d & obcs write_pickup have not yet been updated)
3495    o pkg/monitor:
3496      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
3497      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
3498      - account for deep Atmosphere factor and density factor (anelastic)
3499    o added open boundary conditions capability for seaice HEFF and AREA
3500    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
3501      thermodynamics
3502      - requires a little reorganization, which affects the testreport results
3503        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
3504        so that now the conservative form is tested
3505      - add a few comments
3506    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
3507    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
3508    o add new diagnostics to seaice: advective, diffusive fluxes (only for
3509      multidim-advection, for scheme 2 they are not filled) and transports,
3510      thermodynamic growth rates
3511    o change units of EmPmR (inside the code, + within coupling interface)
3512      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
3513      Affects results @ truncation level (cg2d match) and update output of
3514       experiments: lab_sea(6), global_ocean.90x40x15(10),
3515      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
3516      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
3517      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
3518      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
3519    
3520    checkpoint59h (2007/09/29)
3521    o pkg/exf:
3522      - improve vectorization by moving if-statement out of loops in
3523        exf_mapfields, exf_radiation
3524      - exf_bulkformulae.F: introduce 2D fields and vectorize code
3525    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
3526    o testreport:
3527      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
3528        monitor & update offline_exf_seaice exp. output.
3529      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
3530    o pkg/seaice:
3531      - bug fix in the evp solver: boundary conditions were affected be
3532        masking of zMax/zMin (changes results)
3533      - minor bug fix in boundary conditions in seaice_calc_strainrates
3534        (changes results for no_slip)
3535      - seaice_lsr.F: make interpolation of eta dependent on boundaries
3536      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
3537      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
3538        stress formulation and no-slip boundary conditions
3539    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
3540      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
3541    o pkg/seaice: a first HSALT time stepping equation has been checked in
3542    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
3543      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
3544      without requiring DO-IF statements
3545    o pkg/thsice:
3546      use continuous power-law function for partition of energy between lateral
3547      melting/freezing and thinning/thickening ; old code using step function
3548      still available with #undef THSICE_FRACEN_POWERLAW
3549      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
3550    o testreport: change AD testing : check against results/output_adm.txt
3551      using same scripts as for forward test.
3552    
3553    checkpoint59g (2007/09/17)
3554    o adjoint testing: in preparation for changing testreport:
3555      - output format: cost and grad written on separated lines
3556      - ad output results in directory "results" (instead of "results_ad")
3557    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
3558    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
3559    o pkg/ecco: allow user defined cost function contributions
3560    o testreport:
3561      Allow to choose (per experiment) the list of tested output variables
3562       and the main variable (used to issue a pass/FAIL ) ;
3563      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
3564      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
3565      Also modify printing of summary:
3566       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
3567       b) echo the list of tested variables in the individual summary.txt of
3568          each experiment.
3569    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
3570      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
3571      (but still depend on the tile decompostion of the domain).
3572    o pkg/seaice: change a discretization detail to make the B-grid code
3573      "more symmetric". This change is likely to remove all "ridges/leads" that
3574      where quasi-aligned with the grid in B-grid solutions. It may also be
3575      the solution to the stress coupling issues with the B-grid.
3576    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
3577      remove .cvsignore from input dir. (since testreport no longer run here).
3578    o pkg/thsice:
3579     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
3580     - fix reshaping of sea-ice just after advection:
3581       melt all the ice only if ice-volume is too small.
3582     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
3583       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
3584     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
3585    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
3586      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
3587    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
3588      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
3589      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
3590      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
3591      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
3592      -> update output.txt
3593    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
3594     this affects truncation error: -> update output.txt of exp:
3595      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
3596      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
3597    
3598    checkpoint59f (2007/08/21)
3599    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
3600    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
3601      a bounded range (in forward mode)
3602    o pkg/ecco, ctrl, autodiff and mom_common:
3603     internal parameter controls, completements of implementations
3604    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
3605    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
3606      (not seem any difference in testing results).
3607    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
3608       at face corners.
3609    o pkg/generic_advdiff:
3610     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
3611      loop range indices for computing vertical advection tendency
3612      and do the calculation in the interior only (no overlap) ;
3613      for now, only implemented for SOM advection (to save CPU time).
3614     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
3615    o exch2 adjoint
3616      First set of changes:
3617      - add exch2 hand-written adjoint templates
3618      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
3619        This will require cleanup in pkg/autodiff/*.F
3620        (changed routines currently kept separate in verif. code/)
3621      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
3622        that used to hide exch2 or cubed-sphere specific code
3623        (commented via 'cph-exch2')
3624    o pkg/seaice
3625      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
3626    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
3627       output of global_ocean.cs32x15.thsice .
3628    
3629    checkpoint59e (2007/07/26)
3630    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
3631      for B-grid vector (not yet tested) and C-grid vector (<- only used
3632      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
3633    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
3634      (#ifdef ALLOW_SALT_PLUME)
3635    o gather_2d/scatter_2d: removed halo regions
3636    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
3637      scheme and the corresponding test case (under front_relax dir). For now,
3638      only available with Skew-flux form and not yet tested in realistic set-up.
3639      adjoint: store directives updated, but gradient checks deteriorated,
3640      so maybe GM/Redi adjoint is now broken.
3641    o seaice adjoint
3642      * add AREA, HEFF, HSNOW as control variable
3643        (should not change lab_sea results)
3644      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
3645    o pkg/seaice:
3646      * added computation of saltFlux in seaice_growth;
3647        For time being, sea ice salinity is assumed constant
3648        contribution of snow flooding to freshening of sea ice is neglected.
3649        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
3650        defaults to 0.0 in order to maintain backward compatibility.
3651        Typical values for SEAICE_salinity are 4 to 10 g/kg.
3652      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
3653      * added SEAICE_availHeatFrac, which specifies fraction of surface level
3654        heat content used to melt or grow ice
3655      * commented out cap of HICE: it helps keep ice thinner
3656      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
3657      * applied OBCS T/S mask to HEFFM sea ice mask
3658    
3659    checkpoint59d (2007/06/21)
3660    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
3661     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
3662     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
3663    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
3664     and change default value of parameter "GM_Small_Number";
3665     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
3666       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
3667       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
3668    o pkg/ecco: cost function when applying pkg/smooth to controls
3669    o pkg/ctrl: add forcingPrecond run time parameter
3670    o pkg/seaice:
3671     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
3672     - fix bug in metric terms of u-equation in LSR solver (implicit part),
3673       changes verification/lab_sea
3674     - rearrange implicit part of u-equation in LSR solver to make it easier to
3675       read, understand, and debug. This causes changes at the truncation level.
3676     - fix (serious) bug in the boundary conditions (sign error in the implicit
3677       part) of the LSR solver. Changes all LSR results.
3678     - fixed problem with HSNOW initialization to avoid thick snow when AREA
3679       is initilized with small values - does not change lab_sea results.
3680     - added HsnowFile initialization capability
3681    o pkg/smooth: addition to model/src and pkg/ctrl so allow
3682     initialization of pkg/smooth and application to control vector
3683    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
3684    o dependencies: pkg/profiles requires pkg/cal
3685    o pkg/profiles:
3686     - added option ALLOW_PROFILES_GENERICGRID
3687         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
3688         that interpolation information (grid points and coefficients) is provided
3689         within the netcdf input files.
3690         -> sample matlab scripts can be found in MITgcm_contrib/gael
3691         that allow you to prepare netcdf input files.
3692     - also modified: cleaner include statements, cleaner error print statements,
3693       cleaner stops when error, and more tests of the netcdf input files consistency.
3694    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
3695    o pkg/seaice:
3696     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
3697       requires a new routine: seaice_diagnostics_fill.F
3698     - make sure that seaice does not move if not forced (pressure replacement
3699       method, Hibler and Ip, 1995), changes results
3700     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
3701     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
3702       It is turned off by default (=-1.), because it changes the results.
3703     - make it possible to read AREA from a file, too.
3704    
3705    checkpoint59c (2007/06/04)
3706    o add S/R and diagnostics for oceanic mixed-layer depth
3707    o move GMRedi call after all vertical mixing schemes (including KPP)
3708    o pkg/thsice:
3709     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
3710      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
3711    o pkg/obcs:
3712     - bug fix for balance code
3713    o pkg/seaice:
3714      - allow values of SEAICE_elasticParm > 1
3715      - add new parameter SEAICE_evpTauRelax as an alternative
3716        to SEAICE_elasticParm
3717      - make lsr boundary conditions free slip (by default), changes result
3718      - add code for no slip boundary conditions for lsr
3719      - set minimum of zeta to zero (and not 4e8) (changes results)
3720      - add a cap on AREA after advecting AREA if seaice_growth is not called
3721    o change calculation of Visbeck K:
3722      - no longer depend on tapering scheme; instead, compute slope (limited
3723        by GM_maxSlope). this is equivalent to what was comuted before with
3724        clipping or linear tappering.
3725      - fix vertical averaging (wrong by 1/2 level)
3726      - leave the old version (but will not be maintained) within
3727        #ifdef OLD_VISBECK_CALC / #endif
3728      - update output of exp. ideal_2D_oce
3729    o change error catch in calc_r_star to improve vectorization
3730    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
3731      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
3732    o adjoint:
3733      Re-organized adjoint checkpointing according to Matt Mazloff
3734      (but with modifs/completions/cleanups)
3735      Storing is now bundled into large arrays to optimized I/O
3736      (and second step in cleanup of the_main_loop)
3737    
3738    checkpoint59b (2007/05/16)
3739    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
3740      - export/import (between ocean & coupler) fields needed for ocean DIC.
3741    o pkg/seaice:
3742      - get rid of three more exchanges seaice_calc_viscosities (required
3743        different loop boundaries in seaice_lsr and seaice_ocean_stress)
3744      - bug fix in seaice_ocean_stress (update of lab_sea required)
3745      - reduce loop boundaries to necessary minimum also in seaice_evp
3746      - go back to the old way of computing deltaC/Z as the adjoint likes that
3747        better
3748    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
3749      passive tracer to an Age Tracer) + update output.txt
3750    o pkg/exf:
3751      - implement A-grid / C-grid selection for wind-stress input files.
3752      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
3753      for now, in exf_bulk_largeyeager04.F only :
3754      - change implementation for case where windspeed + 2. components wind-stress
3755        are read-in. AND use rhoConstFresh to convert evap.
3756    o pkg/seaice:
3757      - use correct EXCH_UV for wind-forcing (on A-grid).
3758      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
3759        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
3760    o pkg/exf:
3761      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
3762      EXF_INTERPOLATION:
3763      - merge global_with_exf/code version of exf_interp_read.F
3764        to the main code ;
3765      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
3766        reading the file ; Important: This options needs to be defined to recover
3767        previous code.
3768        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
3769      - no longer loose real*8 precision along the way when using exf_iprec=64.
3770    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
3771      - change discretisation of evp-solver in order to avoid another exchange
3772        (changes lab_sea) and clean up a little
3773      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
3774        help the adjoint (this also changes the results slightly)
3775      - add a few "_d 0" where they had been missing in seaice_evp.F
3776      - cleaning up: remove unused seaice_calc_rhs.F
3777    o pkg/exf: some cleaning-up:
3778      - change various "constants" into runtime parameters
3779      - cleaned-up Large&Yeager04 routine which should eventually
3780        replace exf_bulkformulae.F (changed names of S/R and CPP)
3781        and merged various ALLOW_ATM_WIND options
3782     only used with thsice pkg (in thsice_get_exf.F):
3783      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
3784        which are used when useStabilityFct_overIce=TRUE (= the default)
3785      - change default values of ice & snow emissivity and scale downward LW
3786        by ice & snow emissivity.
3787    o pkg/thsice:
3788     fix few little problems, in thsice_calc_thickn.F:
3789      - growth vertically (and not laterally) if iceFrac == iceMaskMax
3790      - melt only laterally if hIce < hThinIce (as the comments say)
3791      and in thsice_extend.F:
3792      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
3793      - start to form ice as soon as the minimum ice-volume is reachable.
3794     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
3795      and cpl_aim+ocn
3796    o pkg/kpp
3797     - move computation of surface related input fields to KPP into a new
3798       subroutine kpp_forcing_surf.F
3799     - remove wrong (within bi,bj loops) EXCH calls.
3800     - little cleaning (add argument myThid in last position, cvs header ...)
3801     - for now, fix conservation problem by exchanging KPPviscAz (may not
3802       be the best fix)
3803    o pkg/seaice
3804     - check for inconsistent evp parameter/cpp-flag combination
3805     - remove leftover errIO flat for obsolete name list error handling
3806    o OpenAD
3807     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
3808    
3809    checkpoint59a (2007/05/01)
3810    o pkg/seaice: some parameter clarifications and a little bit of clean up
3811    o pkg/thsice: rename run-time parameters:
3812       himin       -> hIceMin
3813       himin0      -> hThinIce
3814       hihig       -> hThickIce
3815       i0          -> i0swFrac
3816       transCoef   -> bMeltCoef
3817       frac_energy -> fracMelting
3818      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
3819       with default values (for now) that do not change the results.
3820      remove old version of thsice vars advection in pkg/seaice.
3821    o in FFIELDS.h:
3822      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
3823      - make pLoad & sIceLoad always available (but still only used if
3824         ATMOSPHERIC_LOADING is #define).
3825    o pkg/kpp: replaced _KPP_RL with _RL
3826    o bug fixes for vertical diffusivity computations when both KPP and
3827        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
3828        are no longer updating the vertical diffusivity array
3829        (passed as argument) but are (re-) setting those arrays.
3830    o pkg/seaice: fix bug in evp solver, while doing that
3831      - change (improve?) discretization of stress computations for both
3832        cgrid-lsr and evp solver
3833      - add a new routine to compute strain rates
3834      - the above changes lab_sea results
3835      - add no slip conditions for evp solver (off by default), lsr-version
3836        may follow
3837      - fix exchange for shear at Z-points (does not change lab_sea)
3838      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
3839        (to force the user to pick a time step since there is not "safe" way
3840        of choosing it)
3841      - add principal stress diagnostics
3842      - rearrange fields for evp a little to avoid having to call a: too many
3843        exchanges and b: exchanges for stress trensor components which we do
3844        not have.
3845      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
3846        of evp, complete rewrite for lsr case (latter is does not yet work
3847        in all cases)
3848    o pkg/kpp: add code to have mixing in shelf ice caverns
3849      - add myThid to all kpp routines (long overdue)
3850    
3851    checkpoint59 (2007/04/19)
3852    o pkg/exf:
3853      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
3854        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
3855      - move exf header files from lower_case.h to UPPER_CASE.h ;
3856        add missing cvs Header & Name
3857      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
3858      - add namelist param. selectStressGridPosition, exf_monFreq
3859      - retire many _CLIM routines, and remove data.exf_clim
3860        + params moved to data.exf
3861        + climsst, climsss now handled by exf_set_gen, i.e.
3862          climss?period=0 refers to constant field,
3863          climss?period=-12 to monthly forcing
3864      - split up namelists in data.exf
3865    o pkg/seaice:
3866      - remove seaice_exch and seaice_exch_uv
3867      - remove superfluous exchange of theta
3868      - add myThid to seaice_budget_ocean/ice
3869      - add new interface for atmospheric wind forcing (C-grid only)
3870        + new routine
3871        + two new field (taux, tauy for stress over ice)
3872        + removed one global field (DAIRN) for C-grid case only
3873    o pkg/thsise
3874      - 2nd set of modifs for thsice adjoint in conjunction with exf
3875    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
3876    
3877    checkpoint58y_post (2007/04/15)
3878    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
3879      vertical diffusivity, similar to that in MOM4; turned on using
3880      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
3881      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
3882    o Added capability for 3D specification of background vertical diffusion
3883      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
3884      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
3885      "data" file that contains the 3D vertical diffusivity coefficients.
3886    o ice dynamics (pkg/seaice) with thsice thermodynamics:
3887      - add code within pkg thsice to advect & diffuse sea-ice fields
3888      similar to (and will replace) what has been added in  seaice_advdiff.F,
3889      but: - conserving Mass, Heat & Salt.
3890           - better when using non-linear advection scheme (not yet fully tested)
3891           - can also be used in atmospheric set-up (for now, only the diffusion).
3892    
3893    checkpoint58x_post (2007/04/04)
3894    o IO option for global-file compact format:
3895      - add options when generating topology (utils/exch2/matlab-topology-generator)
3896      - add I/O capability (pkg/mdsio).
3897      - adapt utils/matlab/rdmds.m to read this format.
3898      for now long-line format not yet supported by pkg/mdsio (& exch2).
3899    o shelfice: add a few diagnostics
3900    
3901    checkpoint58w_post (2007/03/13)
3902    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
3903      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
3904      (and replace horiVertRatio in NH code).
3905      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
3906                         and tutorial_plume_on_slope (sensitive to truncation)
3907    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
3908      directly to drive seaice model (C-grid only)
3909    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
3910     - reintroduce computation of wind from stress,
3911     - compute tau (in exf_bulkformulae.F) from windstress averaged to
3912       mass points to avoid tau = 0
3913     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
3914    o rdmnc.m: make it work with "global" files created with gluemnc
3915    o rdmnc.m : some improvements in dealing with singleton dimension
3916      (tested on all testreport mnc output files).
3917    o genmake2: disable pkg/profiles if netcdf test fails.
3918    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
3919    o move call to cal_readparms up to make calendar parameters/variable available
3920      to all packages
3921    
3922    checkpoint58v_post (2007/02/08)
3923    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
3924      useDynP_inEos_Zc tested.
3925    o pkg/exf: changes to properly interpolate/mask/scale initial fields
3926    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
3927      and portions thereof.  See read_cs.txt for description and examples.
3928    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
3929      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
3930      following the great-circle arc between those 2 points.
3931    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
3932      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
3933    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
3934     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
3935     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
3936     - still needs work (not working with some options ; efficiency to improve)
3937       and serious testing.
3938     - use this scheme for temperature & salinity in 2 advection test exp.:
3939       advect_xy & advect_xz, respectively.
3940    
3941    checkpoint58u_post (2007/01/12)
3942    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
3943    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
3944    o testreport: add option "-skipdir" to skip some test.
3945    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
3946      momentum calculation.
3947    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
3948    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
3949      remove checkpoint.F and the_correction_step.F (no longer used);
3950      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
3951    o add option (linFSConserveTr) to correct for tracer source/sink due to
3952      Linear Free surface
3953    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
3954    o pkg/thsice: fix reading mnc-pickups
3955    
3956    checkpoint58t_post (2006/12/30)
3957    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
3958    o pkg/mdsio:
3959     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
3960       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
3961       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
3962     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
3963     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
3964       either MDS_READ_FIELD or MDS_WRITE_FIELD )
3965     - new S/R (to replace MDSWRITEMETA), which allows to write more
3966       informations (variable names, time ...) to meta files.
3967     - modify rdmds.m to give back the meta file content.
3968    o pkg/diagnostics: change vertical interpolation to be safer, and more
3969       flexible (define p-levels to interpolate to in data.diagnostics);
3970      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
3971       diagnostic pointer.
3972    o pkg/seaice: more cleaning up of seaice_growth, added many comments
3973    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
3974    o fix multi-category seaice:
3975     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
3976       SEAICE_MULTICATEGORY
3977     - fix short wave heat flux
3978    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
3979       and allow to use EVP solver. Change forward lab_sea: test both EVP
3980       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
3981    o Initial check-in of lab_sea adjoint
3982      (very similar to natl_box_adjoint/code_seaice)
3983      * used C-grid and EVP solver
3984      * used KPP, GM/Redi
3985      * uses inAdExact=.TRUE.
3986      * gradient checks fail for both ADM and TLM
3987        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
3988        f.d. gradients actually seem more problematic than ADM, TLM gradients;
3989        issue is related to forward mismatch between g77 an ifort
3990    o pkg/seaice: overhaul of thermodynamics
3991     - growth.F and groatb.F are replaced by new routine seaice_growth.F
3992     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
3993     - move a few global fields out of SEAICE.h into seaice_growth.F and
3994       make them 2D (FICE/QNETO/ ...)
3995     - remove FO (it is the same as QNETO)
3996     - introduce a few local fields to avoid modifying external fields such
3997       as atemp, etc.
3998    
3999    checkpoint58s_post (2006/12/11)
4000    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
4001      changed exf_set_gen.F so that
4002        genperiod=0 means input file is one time-constant field and
4003        genperiod=-12 means input file contains 12 monthly means
4004    o CG2D: use pre-computed solver main-diagonal (stored in common block);
4005      this affects truncation error ; generate new output file for exp. which
4006      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
4007        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
4008        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
4009        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
4010        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
4011        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
4012    o start implementation of deep-atmosphere and anelastic formulation
4013    o verification: remove 2nd copy of input files and use script "prepare_run"
4014      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
4015    o mom_common/vecinv/fluxform: fix a few initialisation isssues
4016    o profiles: fix for multithreaded case
4017    
4018    o diagnostics: rename few diags:
4019      s/'PRESSURE'/'RCENTER '/g
4020      s/'TICE    '/'oceFreez'/g
4021      s/'TAUX    '/'oceTAUX '/g
4022      s/'TAUY    '/'oceTAUY '/g
4023      s/'SWFLUX  '/'oceQsw  '/g
4024      s/DIFx/DFxE/g
4025      s/DIFy/DFyE/g
4026      and add few ocean-forcing diagnostics:
4027      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
4028    o modifications to pkg/seaice/growth.F and budget.F, which change results of
4029      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
4030      as actual snow thickness.  It now refers everywhere to effective snow
4031      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
4032    
4033    checkpoint58r_post (2006/11/17)
4034    o modifications to pkg/seaice/growth.F, which change results of
4035      lab_sea experiment: fixes pertain to melting snow over open water, to
4036      masking EVAP under sea ice, and to using the correct AREA variable for
4037      computations of EVAP, PRECIP, HSNOW, and GHEFF
4038    o add ability to read bathy, salt, and theta using MNC (off by def)
4039    o add flooding algorithm and advection of HSNOW for pkg/seaice;
4040      both are turned off by default and do no change any results
4041    o seaice advection with pkg/thsice: a step toward the use of non-linear
4042      advection scheme, but #ifdef or commented out for now (requires more EXCH).
4043    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
4044      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
4045      in natl_box (affects results @ truncation level: update output.txt)
4046    o multi-threading and IO:
4047      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
4048      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
4049        (needed to work with SingleCpuIO): tested in all verif. exp.
4050    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
4051      affects the results (but none of the verification test uses this scheme).
4052    o Adding some pkg/diagnostics capability to pkg/seaice
4053      (will certainly be subject to changes)
4054    o ctrl: adding new control variables:
4055      lwflux, lwdown, evap, snowprecip, apressure, runoff
4056    
4057    checkpoint58q_post (2006/10/20)
4058    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
4059      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
4060      high_res_cube configuration by 4% on Columbia.
4061    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
4062      add (in global_with_exf/code) a version of EXF_INTERP_READ without
4063      dynamical allocation (seems to work in multi-threaded).
4064    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
4065      single CPU io) so that TAF does not have to see EESUPPORT.h
4066    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
4067    
4068    checkpoint58p_post (2006/09/08)
4069    o obcs: stop if obcs is used with useCDscheme = .true.
4070    o shelfice:
4071     - fix a sign error so that no slip at shelfice interface works
4072     - remove stop for combination non-hydrostatic code and shelfice. That does
4073       not mean, that the results are correct, but at least they are numerically
4074       stable
4075    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
4076    o added adjoint exch routined for all exch*3d* routines
4077      and updated flow directives
4078    
4079    checkpoint58o_post (2006/08/28)
4080    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
4081      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
4082    o change controling S/R for writing pickup file (new S/R do_write_pickup)
4083      and clean-up reading/writing of pickup files.
4084    o fix local version of read/write pickup (NH part) in rotating_tank/code
4085    o simplify EXCH interface:
4086     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
4087     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
4088    o added the regrid package
4089    o shelfice:
4090     - add a simple boundary layer scheme to reduce noise
4091     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
4092    
4093    checkpoint58n_post (2006/08/14)
4094    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
4095       local variable (not in common block).
4096    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
4097      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
4098      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
4099        to work with SingleCpuIO.
4100    o add "_d 0" to real constant of pkg/cfc subroutines ;
4101       update exp. cfc_exemple & tutorial_cfc_offline output files.
4102    o multi-threading and IO:
4103      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
4104        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
4105      - barrier before and after reading.
4106      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
4107      - avoid using MDS_WRITELOCAL for LAND pkg output.
4108      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
4109        common-block variables ; Allows multi-threading with master-thread IO.
4110    o change default MAX_NO_THREADS from 32 to 4 ;
4111      and stop cleanly when MAX_NO_THREADS is too small.
4112    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
4113    
4114    checkpoint58m_post (2006/07/17)
4115    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
4116       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
4117    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
4118       keep global_ocean.90x40x15 (for AD testing) with former secondary test
4119       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
4120    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
4121        add MITgcm_tutorials (= code + all the tutorials)
4122    o ecco, option to compute cost for total ssh (mean+anom)
4123    o consistent with addition of ptracer and ssh in pkg/profiles
4124    o profiles: adding ptracer and ssh
4125    o testreport: change multi-test output-file name
4126      (from output.txt.{name} to output.{name}.txt)
4127    o profiles: now ok for mutli-tiles case
4128    o seaice: add 4 parameters for different advection schemes for area,
4129      (effective) seaice thickness, enthalphy, and snow height. Their default
4130      is the standard parameter SEAICEadvScheme
4131    o calc_gw:
4132     - add cosFacU in zonal viscous flux (harmonic.visc.).
4133     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
4134       of tutorial_plume_on_slope.
4135    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
4136    o calc_gw: true flux-form, account for horizontal grid spacing.
4137      update rotating_tank results, but not plume_on_slope (affected at
4138      truncation level, 11 digits).
4139    
4140    checkpoint58l_post (2006/07/12)
4141    o calc_gw:
4142     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
4143     - remove side-drag for now (need to fix it); update plume_on_slope results.
4144     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
4145    o commit code to make SST/SSS weights spatially variable
4146      (based on either variable in-situ or variable initial T/S weights)
4147    o pkg/ecco:
4148      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
4149        now based on horizontally varying weights wthetaLev, wsaltLev
4150      * cost_averagesflags now returns year indices in addition to day, month
4151      * sflux balance is performed on annual basis
4152        (sflxumm, sfluxmm2, bal_sfluxmm)
4153      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
4154        including separate counting and multipliers
4155    o pkg/rbcs
4156      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
4157    
4158    checkpoint58k_post (2006/07/06)
4159    o testreport:
4160     - always build in dir. "build" (if not there, mkdir build instead of building
4161       & running in input)
4162     - run in dir run (if it exists), in build otherwise.
4163     - call prepare_run (if input/prepare_run exists)
4164     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
4165    o pkg/exf modifications to interpolation and rotation routines for more
4166       reasonable treatment of North Pole singularity: for tracers North Pole
4167       value is set to northernmost zonal-mean value, for zonal velocity it is
4168       set to zero, and for meridional velocity it is set to northernmost value.
4169    o pkg/exf/exf_check_range.F
4170     - add tile index to diagnostics and move stop statement to the very
4171       end of the routine.
4172    o pkg/diagnostics: (diagnostics_main_init.F)
4173      define title of isomorphic variables according to the current config.
4174    o pkg/thsice with pkg/seaice dynamics:
4175    - fix domain of computation (interior only, required for exf) and do exchanges
4176    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
4177    o towards a standard way of dealing with multi-threading in MONITOR
4178      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
4179    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
4180       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
4181    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
4182    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
4183    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
4184       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
4185    o tracer advection:
4186     - clean-up and simplify calc_common_factors.F
4187     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
4188       advection subroutine (but still not used within DST advection S/R)
4189    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
4190    
4191    checkpoint58j_post (2006/06/15)
4192    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
4193      from file (collects calls previously in FORWARD_STEP)
4194    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
4195    o adjoint store dir. adjusted accordingly
4196    o genmake2
4197      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
4198    
4199    checkpoint58i_post (2006/06/14)
4200    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
4201      on wind stress (SEAICEstressFactor defaults to 1.)
4202    o Total number of Timers is finite (<=40): comment out 2 non-essential one
4203      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
4204    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
4205      on CS-grid: no longer loosing mass.
4206    o exf & curvilinear-grid: no longer modify longitude xC & xG.
4207    o pkg/ggl90: fix sloppy output and fix a bug
4208    o pkg/seaice: added SEAICEuseEVPpickup parameter
4209      - Set to false in order to start EVP solver with
4210        non-EVP pickup files when using SEAICEuseEVP
4211      - fix sign error in diffusion in seaice_calc_rhs
4212    
4213    checkpoint58h_post (2006/06/07)
4214    * Modifications for bottom topography control
4215      o replace hFacC by _hFacC at various places
4216      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
4217      o add non-self-adjoint cg2d_nsa
4218      o update autodiff support routines
4219      o re-initialise hfac after ctrl_depth_ini
4220      o works for 5x5 box, doesnt work for global_ocean.90x40x15
4221    * Adding verification for 5x5 box (4-layer) bottom topography control
4222    
4223    checkpoint58g_post (2006/06/07)
4224    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
4225       used for mean seasonal cycle, mean diurnal cycle); add an example
4226       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
4227    o pkg/ggl90:
4228      - add parameter (minimum surface kinetic energy)
4229      - fix bug (avoiding division by zero)
4230    o couple pkg/thsice to pkg/seaice:
4231      - modify advection in seaice to accomodate new scalar fields to be advected
4232      - only muliDimAdection scheme work with seaice/thsice
4233      - mapping of thsice-variables to seaice-variables, back and forth
4234      - does not break the verification experiments, but does not give the
4235        desired results either
4236    o pkg/seaice
4237      - make (default) second order advection a bit less confusing?
4238    
4239    checkpoint58f_post (2006/06/05)
4240    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
4241      to pkg/seaice):
4242      - new routines thsice_map_exf and thsice_get_exf provide the interface
4243      - add an additional formal parameter to thsice_solve4temp
4244    o pkg/exf:
4245      - add new fields wspeed, snowprecip (to be able to couple to thsice)
4246      - correct Stefan-Boltzmann constant
4247      - new parameter for longwave surface emittance
4248      - separate some stuff from exf_bulkformulae into new routines  
4249        exf_radiation, exf_wind
4250      - add new parameters and constants: longwave emissivity for ocean, ice
4251        and snow, evaporation parameters over ice
4252      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
4253        either wind from stress or stress from wind
4254    o pkg/thSIce:
4255    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
4256    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
4257       and THSICE_CALC_THICKN
4258    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
4259    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
4260      to make debugging easier.
4261    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
4262    o pkg/bulk_force:
4263      - clean-up comments and parameters ;
4264      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
4265    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
4266      generate new output for test-experiment: aim.5l_cs.thSI
4267    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
4268      testreport accordingly
4269    
4270    checkpoint58e_post (2006/05/17)
4271    o SEAICE_CGRID adjoint done
4272    o R_STAR adjoint implemented.
4273      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
4274      * need to sort out init. of h0facc, etc.
4275    o Make pkg/profile fully independent of ecco,cost, etc. stuff
4276      to be able to use it in pure forward.
4277    
4278    checkpoint58d_post (2006/04/21)
4279    o upgrade simple test-experiment to tutorial example:
4280     step.1: duplicate the experiment and (step.2) will remove the old copy.
4281      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
4282      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
4283      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
4284      tutorial_global_oce_biogeo    <- copy of dic_example
4285      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
4286      tutorial_plume_on_slope       <- copy of plume_on_slope
4287      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
4288      tutorial_global_oce_optim     <- empty for now (David ?)
4289      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
4290     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
4291    o correct a sign problem in cost_scat.F
4292    o obcs and ptracers: fix boundary conditions for advections schemes
4293      with larger stencil
4294    o thsice adjoint: start
4295    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
4296      completeness
4297    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
4298      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
4299    o ptracers adjoint:
4300      * avoid extensive recomputatations
4301      * fix missing re-init. of gptr (missed by TAF)
4302    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
4303      me to turn off the excessive output to STDOUT that this package produces
4304    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
4305      and add those terms in Vector-Invariant formulation.
4306    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
4307      if the control period (xx_hfluxperiod etc) is 0
4308    o in profiles pkg, clean routines and fix details
4309    o in ecco pkg, reading ssh data:
4310      fix problem in case the model does not start at iter0=0
4311    o fix mnc-pickup/restart for ptracers
4312    o new package prifiles:
4313      code to compute profile-based cost by Gael Forget
4314      (modifs in ecco, ctrl, autodiff)
4315    o Benign bug fix in initialization (spotted by M. Mazloff) of
4316      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
4317    
4318    checkpoint58c_post (2006/03/23)
4319    o adjoint: finish NLFS adjoint and provide reference output in
4320      verification/global_ocean.90x40x15/results_ad_nlfs
4321    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
4322      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
4323      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
4324      with SEAICE_CGRID defined.
4325    o move calendarDumps from "data" to "data.cal" and clean-up the code
4326      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
4327    o add useEXF & useCAL flags (for now, set in hard-coded way)
4328    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
4329      (were missing in NH mode, and wrong in quasihydrostatic mode).
4330      waiting for Chris updated version of calc_gw to add those CALLs.
4331    o fix bug in quasihydrostatic S/R ;
4332      add a test for this option: global_ocean.90x40x15.qshyd
4333    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
4334      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
4335    o add on/off flag useOffLine for package OFFLINE
4336    o seaice:
4337      - modify advection so that it works also on the C-grid
4338      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
4339        problem in multi-tile runs with C-grid
4340      - add flags for clipping ice velocities and/or masking solver forcing
4341      - fix drag (ocean on ice) formulation and a bug that caused noise in the
4342        C-grid solver
4343      - added a few comments to seaice_diffusion.F
4344      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
4345        are now exclusive)
4346      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
4347        required re-ordering the code a little:
4348       + make DAIRN global variable (defined in SEAICE)
4349       + move computation of the viscosities eta and zeta into a new separate
4350         routine (because I need to recompute them in seaice_ocean_stress.F)
4351    
4352    checkpoint58b_post (2006/03/13)
4353    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
4354      update output.txt of exp. aim.5l_cs.thSI
4355    o various mnc cleanups and improvements:
4356      + shrink lookup tables by factor of ~4
4357      + better error reporting when running out of lookup space
4358      + able to handle longer path/file names (up to 500 chars)
4359    o adjoint:
4360      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
4361      - TBD: "hidden" mom_vecinv recomp. in dynamics
4362    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
4363     (allow to differentiate between forcing components using new integer flags:
4364      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
4365     and add new flag to put Dissipation tendency out of Adams-Bashforth.
4366    o ecco
4367      - enable trend removal from SSH anomaly obs.
4368    o adjoint
4369      - a fix for PmEpR when #undef EXACT_CONSERV
4370      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
4371      - try to fix "hidden" recomp. in forward_step for NLFS
4372        (NLFS seems broken sometimes after I checked it in)
4373    o seaice:
4374     - add c-grid version of the dynamic solver:
4375       + three new routines that are the c-grid substitute lsr, dynsolver
4376         and ostres
4377       + put a few fields that were local to dynsolver into global common
4378         blocks, so that I can move the computation of stresses etc into
4379         seaice_lsr (saves coding but may break the adjoint).
4380     - replace more hardwired parameters by runtime parameters
4381     - add ice masks that mask the rhs of the implicit solvers where there
4382       is no ice (commented out in seaice_dynsolver, because i am not sure
4383       if this works properly), eventually this should replace the clipping
4384       of ice velocities in seaice_dynsolver to +/-40cm/s.
4385    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
4386      include it only where its needed
4387    o move balancing of fluxes before the call of external_forcing_surf
4388    o seaice:
4389      - correct units of turning angles (now they are really in degrees)
4390      - move computation of GWATX/Y out of main routine into dynsolver
4391      - initialize GWATX/Y in seaice_init
4392    o Apply mask on Fresh-Water flux (needed for SSH forcing).
4393      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
4394    o seaice: add runtime flags for turning angles (default to zero)
4395    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
4396      and trend from exf forcing and ctrl control adjustments
4397    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
4398      (since checkpoint57x_post)
4399    o change the default rotation period to 86164.s = the Earth rotation
4400    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
4401      and based on a reference stratification. Tested within hs94.cs-32x32x5.
4402    o seaice advection: add code for choosing between the default (2nd order
4403      central differences) and multiDim advection schemes provided by
4404      pkg/generic_advdiff
4405    o seaice:
4406      - removed all references to SEAICE_GRID.h fields from
4407        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
4408        (cubed-sphere configuration will change a little)
4409      - grid computations in seaice_init are obsolete now.
4410      - cleaned up code a little so that is easier to read (hopefully).
4411      - added new (better?) discretizations of default advection and diffusion
4412        (turn on with SEAICEuseFluxForm)
4413      - replace 1 in 3d global fields by kSurface in growth.F
4414      
4415    checkpoint58a_post (2006/02/13)
4416    o seaice:
4417      - bug fix in advect.F
4418    o shelfice:
4419      - separate shelfice load anomaly from pload (breaks with time
4420        dependent forcing), => introduce constant field shelficeLoadAnomaly.
4421        Its default is 0., but it may be computed more cleverly from (unknown)
4422        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
4423        done offline. A good approximation of the pressure load anomaly is
4424        necessary to avoid large initial adjustment processes underneath
4425        deep-reaching shelfice.
4426      - small fix in ISOMIP shelfice_thermodynamics
4427      - add more sophisticated thermodynamics of Hellmer (1989), this is
4428        now the default
4429      - give a few constants more intuitive names
4430    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
4431      if bulk formulae are used in long integration (especially EmPmR). Turn
4432      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
4433      if balancePrintMean, the imbalance that is substracted is printed to
4434      STDOUT.
4435    o fix bug (typo) in obcs_apply_eta.F
4436    o add a new package shelfice which enables us to model the circulation
4437      underneath shelf-ice with draughts of hundreds of meters.
4438     - works
4439     - to do: + include improved thermodynamics
4440              + check whether kSurfC (from model/inc/SURFACE.h) can be used
4441                instead of new field kTopC
4442              + can we use topoFile, Ro_surf and existing code in ini_depth.F
4443                instead of new field R_shelfIce and new code in ini_depth.F
4444                and ini_mask_etc.F?
4445              + adjust vertical mixing schemes?
4446    o seaice pkg:
4447     - add a cpp-flag to include a simple formula for a salinity dependent
4448       freezing point of sea water at the surface
4449     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
4450       meridional stresses are now different (and hopefully correct)
4451    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
4452       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
4453       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
4454    o pkg/diagnostics: add options and parameters for regional-statistics
4455       diagnostics ; define regions by reading a region-mask from a file
4456       (might add other options later)
4457    o pkg/bulk_force:
4458     - add option and parameters to use AIM surface-flux formulae.
4459     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
4460       others forcing fields (defined in PARM05, parameter file "data") are loaded
4461       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
4462     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
4463     - use the right EXCH call for uwind,vwind (to work on CS-grid).
4464     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
4465       and parameters (note: calcWindStress replaces .NOT.readwindstress).
4466     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
4467    
4468    checkpoint58 (2006/01/12)
4469    o add "--embed-source" option to genmake2 which, when the supporting
4470      tools can be compiled (as determined by genmake2) will turn on the
4471      embed_files package which then embeds the entire MITgcm source code
4472      (*.[fFhc] + Makefile) used for the build within the executable
4473      - requested by CNH but off by default
4474      - adds a paltry <9MB to the mitgcmuv executable in most cases
4475      - only writes the output when useEMBEDSRC in eedata is true
4476    o clean up 3-dim. relaxation codes:
4477      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
4478      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
4479      * Thanks to Tom Haine for testing!
4480    
4481    checkpoint57z_post (2005/12/31)
4482    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
4483      affects output (@ truncation level) of exp. plume_on_slope ; updated.
4484    o fix the pickup behavior for obcs in combination with ptracers
4485    o fix a bug in ptracers_external_fields_load
4486    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
4487      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
4488    o transfered surface NH pressure to eta field (if exactConserv).
4489    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
4490         and update lab_sea output.txt file.
4491    o completing 3-dim. relaxation code: additional term
4492         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
4493      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
4494      * At compile time, in "EXF_OPTIONS.h" set
4495          #define  ALLOW_CLIMTEMP_RELAXATION
4496          #define  ALLOW_CLIMSALT_RELAXATION
4497      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
4498          tauThetaClimRelax3Dim = 15552000.0,
4499          tauSaltClimRelax3Dim  = 15552000.0,
4500      * 3 cases:
4501          1) Use a constant-in-time 3-dim. field
4502          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
4503          3) Real-time relax. to time-evolving prescribed field
4504    o Adding Laplacian-type smoothness constraint on
4505      initial and boundary (forcing) controls (ic, bc)
4506      * enable at compile-time via
4507        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
4508      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
4509      * Absolute scale somewhat unclear so far
4510      * no area weighting was included since no other cost term does so far
4511    
4512    checkpoint57y_post (2005/12/08)
4513    First step for a NLFS adjoint
4514    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
4515    o new init. routines for calc_r_star, calc_surf_dr
4516    o still need to deal with ini_masks_etc
4517    o testreport seemed happy
4518    checkpoint57y_pre (2005/12/08)
4519    
4520    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
4521    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
4522    o add new offset feature to offline pkg (plus minor cleanup)
4523    o cfc fixes for final year of integration
4524    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
4525      be in GCHEM_OPTIONS).
4526    
4527    checkpoint57x_post (2005/12/04)
4528    o fix testreport Pb in multiple test experiment.
4529    o cleanup our namelist syntax in verification:
4530      - make it more F95 standards compliant (some work still needed)
4531      - allows the vast majority of our tests to work with gfortran
4532    o Non-Hydrostatic:
4533     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
4534     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
4535    o Allow to apply AB on T,S rather than on AB(gT,gS):
4536     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
4537     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
4538       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
4539     - need a "clever" read_pickup to restart from the other AB formulation
4540    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
4541    o remove some unused variables (reduces number of compiler warnings)
4542    o adjoint
4543      * Disable useVariableViscosity for adjoint for time being
4544        (there are a number of extensive recomputations)
4545      * Initialize certain variables needed for adjoint
4546    
4547    checkpoint57w_post (2005/11/03)
4548    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
4549                 fix the singleCpuIO RS version of MDSWRITEFIELD
4550       and add a WARNING if using globalFiles=T with multi-processors.
4551    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
4552      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
4553    o tracer advection scheme:
4554      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
4555       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
4556       was not very convenient).
4557      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
4558       (further tests needed for the implicit DST & Flux-Limiter schemes).
4559    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
4560      and sRef for convenience, handy, when you want to initialize
4561      ptracers in a large domain with a constant non-zero value. Also,
4562      untangle ptracers_init.F a little.
4563    
4564    checkpoint57v_post (2005/10/13)
4565    o change dome exp. to use variable viscosity in side-drag terms.
4566    o remove all the files from the cfc_offline test since they are now
4567      incorporated into tutorial_cfc_offline which has been producing
4568      identical results for a few days of testing
4569    o add new parameter: sideDragFactor to enable half-slip-side BC
4570      and change side-drag S/R to use viscosity from mom_calc_visc
4571      (can switch back by setting sideDragFactor=0.); affects results at
4572      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
4573       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
4574    o vorticity & strain are now computed without masking, to account for
4575      no-slip-side BC in variable viscosity calculation ; mask is applied
4576      anyway later on, before computing advection/coriolis terms.
4577    o modify exp4 to test new obcs support for reading from external files
4578      and for passive tracers
4579    o fix behavior of ptracers_monitor when monitor output is written to a
4580      netcdf-file; still not independent of monitor.F (writes in the same
4581      file).
4582    o change default value of tRef (put a uniform, meaningful value for ocean
4583      & atmos) and initialize sRef (was missing, as Martin mentioned).
4584    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
4585      to be proportional to enstrophy dissipation length.  Thus,
4586       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
4587      This is now consistent with Smagorinsky and with the manual.
4588    
4589    checkpoint57u_post
4590    o OBCS and PTRACERS: add open boundary support for passive tracers
4591      - either use homogenous (pseudo) v.Neumann conditions or prescribe
4592        OB-values from file; this is not different from the way theta and salinity
4593        are treated
4594      - however, Orlanski-radiation conditions are not supported, and the model
4595        will stop if you use pTracers and Orlanski at the same time.
4596      - beefed up the rountine obcs_external_fields_load: now only those open
4597        boundary values are overwritten with values from files for which there
4598        are really files, otherwise the OB-fields remain untouched. This makes
4599        it possible to use different OBs at different ends of the domain (as
4600        with EXF)
4601    o reduce number of exch calls in shap_filt (s2).
4602    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
4603      truncation level) 4/5 MLAdjust test results (11&12 digits match).
4604    
4605    checkpoint57t_post (2005/10/03)
4606    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
4607    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
4608      same truncation, independent of the face number: affects affects several
4609      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
4610    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
4611      note that biharmonic viscosity + no-slip was not tested in any experiment.
4612    o fix bug in non-linear free-surf side-drag ; generate new output for
4613      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
4614    o make mnc honor the writeBinaryPrec flag for most kinds of output
4615    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
4616    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
4617      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
4618    o add brackets in multi-terms sum to get same truncation, independent of
4619      the face number (manage to get exactly same value of gU,gV at the cs-edge)
4620      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
4621    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
4622      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
4623      a maximum grid-scale Reynolds number.  Also, changes all length calculations
4624      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
4625      Suggested values of viscosity parameters found in mom_calc_visc.
4626      Many new viscosity diagnostics available.
4627    
4628    checkpoint57s_post (2005/09/20)
4629    o Add clearing-house for viscosity calculations, mom_calc_visc and
4630      correct numerous bugs in LeithD and Smagorinsky discretizations.  
4631      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
4632      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
4633      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
4634      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
4635      The Strain-Tension form is now called with useStrainTensonVisc=.true.
4636      ViscAhStrain and viscAhTension are now retired.
4637    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
4638    o In response to JMC's bug report, genmake2 now ignores any soft-links
4639      that it finds in the *current* directory when searching for files.
4640      Soft-links found in any other source directories will still work as
4641      they did before.
4642    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
4643      a C routine to unlimit the stack size
4644    o mnc-ify pkg/aim snapshot vars
4645    o mnc-ify pkg/land as requested by Daniel
4646    o various changes to mnc including:
4647      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
4648      - output can now be grouped so that all files within a group
4649          change the ITER portion of their names in lock-step together
4650      - can now read ("global") PER-FACE (in addition to PER-TILE) files
4651          and works with both EXCH1 and EXCH2 (but needs more testing)
4652      - writing works for all verification test cases w/ g77 on Linux
4653    
4654    checkpoint57r_post (2005/09/07)
4655    o make MNC variable initialization happen earlier

4658    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
4659    o remove MINIMAL_TAVE_OUTPUT option ;
4660      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
4661    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
4662      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
4663    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
4664    o add time-dependent SST, SSS control
4665    o cost terms in ecco/ modularized (new cost_generic.F)
4666    o cost_averages routines are modularized (new cost_averagesgeneric.F)
4667    o new infrastructure for seaice model vs. obs misfits in seaice/
4668      * driver from the_main_loop.F is seaice_cost_driver.F
4669      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
4670      * gradient check in Exp. 6a of natl_box_adjoint/
4671    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
4672      (see README file)
4673    
4674    checkpoint57q_post (2005/08/19)
4675    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
4676    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
4677      - bug was reported by Jean-Michel and Ian Fenty
4678    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
4679      update exp. cpl_aim+ocn output.
4680    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
4681      Needed for high-res. runs with large global files
4682      to be able to limit tapelev size
4683    o Changed some tests for adjoint:
4684      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
4685      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
4686      * global_ocean.90x40x15/ back to default 3-level checkpointing
4687    o Modifications to enable scripted COMMON to MODULE conversion
4688      * verification/OpenAD/code/ has necessary scripts and description;
4689      * converts, compiles and runs successfully;
4690    
4691    checkpoint57p_post (2005/08/01)
4692    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
4693    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
4694      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
4695    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
4696    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
4697      (was already the case for dissipation with mom_vecinv,
4698       and also the case for grad.PhiHyd when staggered-timeStep)
4699      This will allow to put dissipation out-off the AB time-stepping.
4700     Unfortunately, affects truncation error. Update output of exp. that "fails"
4701      (cg2d matching number) and leave the others for later: front_relax(10),
4702      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
4703      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
4704    
4705    checkpoint57o_post (2005/07/30)
4706    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
4707      (2) its ready to be documented during the 20050801 DocFest
4708    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
4709      for ideal_2D_oce and lab_sea on linux_ia32_g77
4710    o set to #undef CTRL_SET_OLD_MAXCVARS_30
4711      in global1x1_tot/code_seaice_adj to access indices 32, 33
4712      (worth another tag)
4713

4715    o adding precip control xx_precip 32
4716    o adding swflux control xx_swflux 33
4717    o Replacing 10 forcing penalty cost routines by 1 generic.
4718    o Implementing partitioning in time-mean and variable adjustment
4719      for atmos. state.
4720    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
4721    o in natl_box_adjoint:
4722      * updated exp 1 to 10
4723        (but does not have time-mean vs. variable split results yet)
4724    o updated global1x1/*_seaice_adj/
4725      to incorporate latest changes
4726    o enable useSingleCpuIO for mdsio vector routines
4727      (applies in particular to tapelev I/O)

4729    
4730    checkpoint57m_post (2005/07/28)
4731    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
4732      and advect_cs (use EXCH-2 and standard cs-32 grid files).
4733    o pkg/exch2: filling of face-corner halo regions is optional
4734      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
4735    
4736    checkpoint57l_post (2005/07/14)
4737     tag before updating tutorials (pre-release-2)
4738    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
4739       for output and interpolation of input fields onto model grid)
4740    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
4741       Affects results of exp. rotating_tank ; update output.txt.
4742    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
4743          and taking the square quantity and/or using a fraction-weight field.

4747    
4748    checkpoint57k_post (2005/07/02)
4749    o lab_sea now uses diagnostics package and provides a suite of
4750      new EXF diagnostics output.
4751    
4752    checkpoint57j_post (2005/06/30)
4753    o exf
4754      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
4755        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
4756        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
4757      * extended diagnostics output
4758        - now includes all EXF variables
4759        - hs, hl moved to common block
4760        - separate S/R for diagnostics, called after ctrl vector is added
4761        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet

4765        to ensure that diagnostics sees a true EXFqnet
4766    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
4767    o diagnostics pkg: change pointers so that 1 diagnostic can be used
4768      several times with different frequencies.
4769    o mnc-ify the thsice package as requested by Daniel Enderton
4770      - the monitor--MNC output needs work
4771      - many attributes need to be added (most are currently blank)
4772    o mnc-ify theaim_v23 package as requested by Daniel Enderton
4773      - many attributes need to be added (most are currently blank)
4774    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)

4779    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
4780     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
4781    
4782    checkpoint57i_post (2005/06/19)

4789      end-run around the C/Fortran linking horror in eesup/src/timers.F
4790    o added pkg/runclock: allows user to terminate run based on wall clock
4791    o added non-hydrostatic scaling parameter: nh_am2
4792    o pkg/my82: futile attempt to make results compiler-independent by adding
4793      some "_d 0", etc. no effect.
4794    o for mnc output, fill the 'T' coordinate var with myTime and create a
4795      separate 'iter' variable for iteration count
4796    o pkg/diagnostics:
4797      add new capability: output of Global/Regional & per-level statistics ;
4798      tested against monitor output (including land & thSIce) on various exp.
4799    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
4800    
4801    checkpoint57h_done (2005/05/19)
4802      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
4803      data.diagnostics, data.gchem, data.ptracers) is done.
4804    
4805    o pkg/diagnostics: prepare for Global/Regional statistics.
4806      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
4807    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
4808      and rename it: DIFFERENT_MULTIPLE
4809    
4810    checkpoint57h_post (2005/05/14)
4811    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
4812    o pkg/diagnostics: change output frequency, now in seconds (instead
4813      of Nb of iterations). This requires to change data.diagnostics.
4814    checkpoint57h_pre (2005/05/12)
4815    
4816    o in mnc, let the user create the output dir if both mnc_outdir_date
4817      and mnc_outdir_num are false
4818    o add fflags() to pkg/diagnostics which allows one to specify, on a
4819      per-file basis, the file precision [default behavior is unchanged]
4820    o added diagnostics to pkg/kpp, including computation of mixed layer
4821      depth based on a temperature/density criterion
4822    o updated verification/natl_box to test the new pkg/kpp diagnostics
4823    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
4824    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
4825    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
4826      not mnc -- this mistake was found by JMC and is now corrected
4827    
4828    checkpoint57g_post (2005/04/15)
4829    o add Adams-Bashforth 3rd Order time stepping:
4830      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)

4832    checkpoint57g_pre (2005/04/15)
4833    
4834    o make lambda[Theta,Salt]ClimRelax spatially varying
4835      (default remains spatially uniform constant based on tau)
4836    o added new control variables
4837      * init. uVel, vVel, etanN
4838      * lambda[Theta,Salt]ClimRelax
4839    o separate masks used for ctrl_pack/unpack 'from write_grid' output
4840      (suggested by G. Forget)
4841    
4842    checkpoint57f_post (2005/04/06)
4843    o add parameter "baseTime" = model base time = time at iteration zero
4844      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
4845      account for baseTime shift
4846    o move Coriolis arrays from PARAMS.h to GRID.h
4847    checkpoint57f_pre (2005/04/06)
4848    
4849    o mnc-ifying the seaice package
4850    o introduced an alternative length scale calculation for use in the limiting
4851      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
4852    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
4853    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
4854      as well as grad(vort3).  Made it compatible with both approximate form
4855      for the cubed sphere and full form of these gradients.  Added flag
4856      useFullLeith to select between approximate and full form.  
4857    o add "d0" in getcon.F to reduce differences between compilers/platforms
4858      update output.txt of exp. fizhi-gridalt-hs
4859    o change port_rand funtion to allow to set the seed.
4860    o fix obscure MNC bug involving conversion between reals and integers
4861      - it caused no problems with certain (eg. gcc, ifc) compilers but the
4862        new version is now more standards-compliant
4863    o adjoint-related modifications
4864      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
4865      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
4866      * mom_vi_hdissip: to be able to use Leith scheme in adjoint

4873      update output.txt of exp. fizhi-gridalt-hs
4874    o add more "Z" dimensions and associated coordinate vars to MNC
4875    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
4876    o parameter calendarDumps: when set, approximate months (30-31 days) and years
4877      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
4878      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
4879      months and years.  Requires pkg/cal.
4880    o diagnostics: add pickup functionality
4881      - off by default for backwards compatibility
4882      - current version only uses MDSIO -- MNC will be added
4883    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
4884    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
4885    
4886    checkpoint57d_post (2005/02/11)
4887    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
4888    o modify verification/ideal_2D_oce so that it tests the creation of mnc
4889      output from the diagnostics package
4890    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
4891    o make genmake2 more portable by using ".$FS" instead of ".f" for more
4892      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
4893    o add coordinate variables to the MNC output from the diagnostics package
4894    o change MNC-flags default value: true when useMNC=TRUE
4895    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
4896      the ability (off by default) to read the grid information using MNC
4897    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
4898    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
4899    o do snap-shot diagnostics at the middle of the time-interval (instead of
4900      at the end).
4901    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
4902      new test for AIM with thSIce + slab-ocean
4903    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
4904    o move state variable diagnostics to the beginning of the time step ;
4905      (note: still needs some work specially for snap-shot diagnostics)
4906      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
4907    
4908    checkpoint57c_post (2005/01/27)
4909    o Change testing option (-ieee) to get closer agreement between g77 & ifort
4910    o generate new output.txt files on faulks with g77 & the new -ieee option
4911    checkpoint57c_pre (2005/01/27)
4912    
4913    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
4914      update output.txt of exp. global_ocean.90x40x15
4915    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
4916      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
4917    o add saltFlux(+File) forcing capability with periodicExternalForcing
4918    o allow to use pkg diagnostics for GM-Redi & ThSIce output
4919    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
4920    o improvements for the MNC output from DIAGNOSTICS:
4921      - correct handling of the unlimitied dimension
4922      - all dims now have associated coordinate variables
4923      - variables located at U, V, and Corner ("Z") points are now written
4924        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
4925        *all* data points are output
4926    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
4927    o added pkg/seaice/seaice_monitor.F
4928    o mdsio_readfield.F can now read files visible only to master MPI process.
4929    o pkg/seaice: some test code for ice-modified ocean stress
4930    o exf_getffields interpolation defaults to bilinear for all scalar forcing
4931      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
4932      spurious negative numbers for precipitation and humidity.  Will cause
4933      some small numerical differences for integrations using pkg/exf/exf_interp.F.
4934    o pkg/ctrl/
4935      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
4936        May be enabled via doPackDiag
4937      *  introduce z-scaling of
4938         + gradient (doZscalePack) and
4939         + control (doZscaleUnpack)
4940    o pkg/mdsio/
4941      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
4942      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
4943    
4944    checkpoint57b_post (2004/12/20)
4945    o simplify options in diagnostics_fill arguments (remove weird combinations)
4946    o fix MNC coordinate variables so that they now contain per-face index
4947      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
4948      general, EXCH2 grids are only aligned to a "local" coordinate system
4949    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
4950    o Implement instantaneous output within pkg diagnostics:
4951      setting a negative frequency in data.diagnostics produces
4952     "snap-shot" output (as opposed to time-average if freq > 0)
4953    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
4954      NOTE: change ptracer diagnostics name: use 2 characters to work with
4955            more than 9 tracers. Add also diagnostics of advect & diffus flux.
4956    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
4957      becomes the coordinate variable for the 'T' dimension
4958    o add CF-style coordinate variables to MNC
4959      - just a first cut:  numbers are meaningless on the cubesphere and
4960        missing along the T axis but otherwise it works!
4961    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
4962    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
4963    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
4964      this is based directly on what the model compute, so that the content of
4965      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
4966    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
4967    o clean up build options files for SunOS, in particular
4968      - remove -traditional from xmakedepend
4969      - change -xarch=v9 to -xarch=native for f77
4970      - restore use of make (not gmake)
4971      - add CC=gcc if using g77
4972    o changes per discussion of AM, JMC, & EH3 today:
4973      - move redundant "grid" variables out of "state" -- in preparation of
4974        creating proper CF-style coordinate variables and in recognition
4975        that any/all grid variables can be easily copied (eg. w/NCO) from
4976        the grid files into any of the other NetCDF files
4977      - *always* output grid variables with MDSIO (this will eventually be
4978        changed)
4979      - output MNC grid file if useMNC is true
4980    o every instance of _END_MASTER() has been found and replaced with
4981      _END_MASTER( myThid ) in order to satisfy certain picky Sun
4982      preprocessors
4983    o re-arrange diagnostics pkg initialisation:
4984     - allow each package to extend the available diagnostics list
4985     - add some checking and fix small problems (multi-threaded, ...)
4986     - new S/R diagnostics_fill (replace fill_diagnostics):
4987       look through the short list of active diag. (instead of the long list)
4988       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
4989    
4990    checkpoint57a_post (2004/12/10)
4991    o this set of changes restores TAMC compatibility
4992      tested for global_ocean.90x40x15 adjoint on trough
4993      (what a pain)
4994    
4995    checkpoint57a_pre (2004/12/10)
4996    o some modifs in tools/build_options for sunos
4997    o call ctrl_pack for ctrl at end for optimcycle=0
4998    
4999    checkpoint57 (2004/12/09)
5000    o add horizontal bi-harmonic viscosity for vertical velocity
5001      - new parameter viscA4W (defaults to viscA4)
5002      - affects only non-hydrostatic code
5003      - to be done: no-slip lateral boundary conditions
5004    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
5005    o implement Implicit Vertical advection for pTracers
5006    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
5007      (implemented also for implicit vertical diffusion & advection)
5008    o OBCS: extend application of tracer open boundary conditions
5009      to a strip beyond the boundary of width Olx/Oly
5010    o add call monitor to TAF set of required calls (flow directives)
5011      and include in natl_box_adjoint
5012    o untangle a few ifdefs related to cost, ctrl, autodiff
5013      untangel a few ALLOW_ECCO_OPTIMIZATION
5014    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
5015      (theta2, salt2 in ecco_cost_weights)
5016    
5017    checkpoint56c_post (2004/12/03)
5018    o OBCS as control variables
5019      - update ctrl_ad_diff.list, obcs_ad_diff.list
5020      - remove balance of obcs controls from default
5021      - fix index bug nobcs in ctrl_init
5022      - fix dummy fields filen in ctrl_pack
5023      - add dummy weights for obcs
5024    o lsopt: comment out fort.94 output
5025    o optim:
5026      - remove unnecessary header files
5027      - adjusted namelists
5028      - add xerbla.F to Makefile
5029    o exf:
5030      - multiple modifications of exf_check_range
5031      - unit change in exf_init_runoff from [m/year] to [m/s]
5032    o mdsio:
5033      - i/o-vector change debugLevel from debLevA to debLevB
5034    
5035    checkpoint56b_post (2004/12/01)
5036    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
5037      is called from DO_THE_MODEL_IO
5038      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
5039      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
5040      - clean up PTRACERS_WRITE_TIMEAVE a little
5041    o add another verification experiment that tests both the cfc-pkg and
5042      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
5043      reactive tendencies treated inline with regular timestepping
5044    o testreport previously did a lousy job of comparing small numbers, so
5045      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
5046      implemented in the little c-progam tmp_cmpnum.c which is embedded in
5047      testreport.
5048    o ptracers_monitor: bug fix for MPI
5049    
5050    checkpoint56a_post (2004/11/28)
5051    o GCHEM: finish reorganizating the package
5052      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
5053        (introduces another 3D-array for each passive tracer, but only if
5054        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
5055        gchemTendency is not needed because the timestep is done separately)
5056      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
5057      - GCHEM is now---more or less cleanly---separate from PTRACERS
5058      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
5059        so clear to me how that should be done in a general way.
5060    o CFC: improve formatting of output in CFC_ATMOS
5061    o PTRACERS:
5062      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
5063        that ALL experiments with ptracers enable can be checked. This makes
5064        GCHEM_MONITOR obsolete.
5065      - include a runtime parameter PTRACERS_monitorFreq that defaults to
5066        monitorFreq
5067      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
5068    o add PTRACERS (PTR0[1-5]) to testreport output
5069    o exf_check_range:
5070      * default changed to .TRUE.
5071      * will check values for niter0 if debLevA, every timestep if debLevB
5072      * STOP in exf_check_range if 'out of range'
5073      * range chosen generous to allow for potential extema
5074      TBD: a version with stricter range
5075           permitted range would be runtime parameters
5076    o GMredi:
5077      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
5078      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
5079      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
5080    o GCHEM:
5081      - move call to GCHEM_FORCING_SEP, so that it is now called before
5082        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
5083      - introduced a useGCHEM runtime flag and applied it everywhere.
5084      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
5085        this flag is now only visible within GCHEM-pkg routines.
5086      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
5087        be replaced by a 3D array that is computed before thermodynamics; for
5088        this, the tracer ID iTracer had to be included into the parameter list
5089        of ptracers_forcing
5090      - set up forward_step to call gchem_forcing, that will replace
5091        gchem_forcing_int in ptracers_forcing
5092      - cleaning up
5093    o small cleaning of exch2: remove files that are also in eesupp/src
5094    
5095    checkpoint56 (2004/11/17)
5096    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
5097    o mnc: cleanup "full" files--fixes out-of-memory problem
5098    o ECCO-GODAE
5099      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
5100      * fully merged and updated from SIO code
5101        windstress sign change affects
5102        - exf_inscal_[u/v]stress
5103        - sign of xx_tau[u/v] adjustments
5104        - signs in cost_scat
5105      * ctrl_get_gen: avoid update of tau[u/v] for first few days
5106      * natl_box_adjoint updated and compressed
5107      * 2-level checkpoint switch added
5108        (tested in EXP. 1 of natl_box_adjoint)
5109      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
5110    o SVD
5111      * first complete, non-hacked version for SVD calculations
5112      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
5113        performed via direct access files admtlm_vector.it????
5114        (via ctrl_[un]pack)
5115      * optimcycle is used for ARPACK iteration counter
5116        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
5117      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
5118        and add linear transforms where necessary
5119      * controls are initial/final SST, SSS (can be extended; need to check
5120        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
5121    o mdsio: filename info to both stderr, stdout
5122    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
5123      from sign change
5124    
5125    checkpoint55j_post (2004/11/10)
5126    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
5127      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
5128    o add consistent build directories and .cvsignore files to verification
5129    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
5130    o make all subroutines 30 or less characters in length for certain older
5131      compilers to work (a thorough search only turns up two routines in
5132      pkg/ptracers)
5133    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
5134      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
5135    
5136    checkpoint55i_post (2004/10/28)
5137    o change arrays for total vertical diffusivity (2.D if explicit,
5138      3.D if implicit) ; each ptracer uses its own background value.
5139    o added mnc/NetCDF output capability to ocn_compon_interf
5140      - added bits to verification/cpl_aim+ocn so that it can run on
5141        ITRDA and other clusters without the mpirun "-wd" option
5142    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
5143      configuration
5144    o give MNC the ability to create additional files rather than
5145      exceeding a specified file size limit "MNC_MAX_FILESIZE"
5146      - the default is just less than 2GB which is a practical limit
5147        on many systems
5148    o Compute the non-local term using either KPP vertical diffusivity (=default)
5149       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
5150    
5151    checkpoint55h_post (2004/10/20)
5152    o add verification test "vermix"
5153    o remove all the *_ioinc flags and replace with the single global
5154      outputTypesInclusive flag
5155    o allow to set a vertical profile of vertical diffusivity for T & S
5156    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
5157    o useMNC moved from data.mnc to data.pkg
5158    
5159    checkpoint55g_post (2004/10/14)
5160    o Renaming carbon AD experiments to comply with testreport conventions
5161    o Updating adjoint of Held-Suarez hs94.1x64x5
5162    o Fixing directives for non-ECCO forward_step, after ECCO directives
5163      have been fixed to avoid recomp. of do_oceanic_phys
5164      Works well for global_ocean.90x40x15,
5165      but recomp. issue remains for carbon
5166    o Updating adjoint output for natl_box_adjoint after
5167      pkg/ecco has been modified (see taga c55d_post)
5168    
5169    checkpoint55f_post (2004/10/13)
5170    o rename to timeave_init_fixed
5171    
5172    checkpoint55e_post (2004/10/13)
5173    o some delicate re-shuffle of store directives to avoid one
5174      extra call of do_oceanic_physics
5175      affects ecco_the_main_loop.F, do_oceanic_physics.F
5176      checkpoint_lev1_directives.h
5177    o NB: this may break global_ocean adjoint temporarily,
5178      but it is clear how to fix it. Will do later, need this now.
5179    
5180    checkpoint55d_post (2004/10/11)
5181    o ECCO specific cost function terms (up-to-date with 1x1 runs)
5182    o ecco_cost_weights is modified to 1x1 runs
5183    o modifs to allow observations to be read in as
5184      single file or yearly files
5185    o enable to read exf forcing fields as either
5186      single file or yearly files (flag useExfYearlyFields)
5187    checkpoint55d_pre (2004/10/08)
5188    
5189    o switch between 2-level and 3-level checkpointing
5190    o add ability of MNC to write local and "partial" (eg. 2D slices where
5191      the full 3D field is never actually stored) arrays to NetCDF files
5192      with the correct (that is, the complete multi-dimensional) set of
5193      array indicies
5194      - used in mom_vecinv() to write the diagFreq output
5195      - tested (demonstrated) in verification/aim.5l_cs
5196    o further mnc-ification
5197      - add verification/lab_sea to the list with mnc setups
5198      - fix undefined mnc v-names in cd_code
5199      - add kpp to mnc output (both snapshot and timeave)
5200    o non-hydrostatic code
5201      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
5202        in calc_gw.F
5203      - defaults to viscAh
5204      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
5205        friction or Leith) in non-hydrostatic mode, as long as there is
5206        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
5207    o pkg/cost
5208      extend simple cost functions to treat time mean quantities
5209      (T,U,V) via cost_accumulate_state from cost_tile
5210    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
5211        be 2 times larger than the minimum size the advection scheme requires.
5212        now get a perfect conservation of salt in advect_cs test-exp (updated)
5213    o GGL90 (Gaspar's TKE mixed layer)
5214      - add horizontal diffusion of TKE, requires exchanges in
5215        do_fields_blocking_exchanges, horizontal diffusivity is zero by
5216        default. In OPA there is no horizontal diffusion of TKE but the
5217        mixing coefficients are computed from a horizontal average of TKE of
5218        6 points or so. I think that diffusion has a little more physical
5219        justification.
5220      - clean up ggl90_calc in the hope of reducing memory usage (this hope
5221        was in vain)
5222      - mask tke-variable in ggl90_init
5223    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
5224    o fix biharmonic diffusion on CS-grid.
5225    o more obcs stuff
5226      - added obcs_external_fields_load as an alternative to the EXF-pkg option
5227        for reading boundary values. This routine is called from
5228        obcs_prescribe_read
5229      - updated obcs_check
5230      - changed sponge layer relaxation parameter units for days to seconds
5231      - turned off sponge layer by default
5232      - changed argument list of OBCS_CALC to myTime+deltaTclock
5233      - fixed about 35 bugs in obcs_external_fields_load
5234    
5235    checkpoint55c_post (2004/09/23)
5236    o obcs stuff
5237      - new runtime flags useOBCSprescribe, useOBCSbalance
5238      - re-arranged obcs_calc
5239      - moved exf_getobcs to obcs_prescibe_read
5240        obcs_prescibe_read is called after ORLANSKI stuff
5241        and independent of it (executable can contain all).
5242      - updated obcs_check
5243      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
5244        These may be necessary only if tangential velocities are
5245        prescribed at OB, not sure, needs testing.
5246    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
5247      which simplifies the calls and passes the ifc check-bounds test
5248    
5249    checkpoint55b_post (2004/09/22)
5250    o add a 2D scalar, Z location, exchange_2 routine.
5251    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
5252      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
5253      affects advect_cs results (for the wrong reason): update output.txt
5254    o use a more standard discretization for biharmonic viscosity ;
5255     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
5256      affects results of dome set-up: update output.txt
5257    o fix gad_advection.F (CubedSphere part), back to version 1.23
5258    o fix bug in mom_vi_del2uv.F (CubedSphere part).
5259    
5260    checkpoint55a_post (2004/09/20)
5261    o merged code to
5262      * prescribe/read time-dependent open boundaries
5263        (works in conjunction with exf, cal)
5264      * sponge layer code for open boundaries
5265      * each boundary N/S/E/W now has its own CPP option
5266        (healthy for the adjoint)
5267    
5268    checkpoint55 (2004/09/17)
5269    o up-to-date adjoint of previous breaks
5270      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
5271      - global_ocean_ebm: adjoint still needs fix (TLM ok)
5272      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
5273      - carbon: * remove tr1-related adjoint verification
5274                * add ptracer as control variable
5275    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
5276      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
5277    
5278    checkpoint54f_post (2004/09/16)
5279    o in verification/carbin/ remove experiment related to
5280      ALLOW_PASSIVE_TRACER (array tr1 etc)
5281      code_ad/ input_ad/ results_ad
5282    
5283    o add two new packages
5284      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
5285        + subject to optimization (memory)
5286      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
5287        + subject to reordering (many GOTOs in the original code)
5288        + so far opps is called for every (i,j) point, and then operates in
5289          the vertical; one may want to reorder the scheme in order operate in
5290          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
5291          fields)
5292    o overhaul of IO so that we now have flags for MDSIO and/or MNC
5293      - all verification tests compile and run with linux_ia32_g77
5294      - defaults are compatible with current input files--nothing
5295        should change if you were not previously using MNC
5296      - MNC output has been added in numerous places (eg. timeave)
5297        but there are still a few writes not yet do-able with MNC
5298        (this is in progress)
5299      - flags now allow for either/or/both use of MDSIO and MNC and
5300        documentation will soon follow
5301      - numerous small formatting cleanups for ProTeX
5302    o add version info (via BUILD_INFO.h) to MNC and stdout
5303    
5304    checkpoint54e_post (2004/09/02)
5305    o add two new packages
5306      - pp81 (Packanowski and Philander, 1981), Richardson number and
5307        stratification dependent mixing
5308      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
5309      - these scheme operate in a similar manner as KPP (without ghat, of
5310        course), however there is only one diffusivity that is used for both
5311        temperature and salinity (and passive tracers)
5312    o add offline package
5313    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
5314      provided by Stephanie Dutkiewicz
5315    o genmake2: add ability to search for C compilers and cleanup test output
5316      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
5317    
5318    checkpoint54d_post (2004/07/27)
5319    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
5320    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
5321      leading to additional shift by 5 days each year of integration
5322       (i.e. leading to considerable offset over the years)
5323    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
5324    o start with no AB and no initial filtering (staggerTimeStep):
5325      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
5326    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
5327      (external loading & cpl import/export stay in forward_step.F)
5328    o update coupling interface to work with new staggerTimeStep
5329    o change MDSIO ptracers_pickup.
5330    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
5331    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
5332    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
5333    
5334    checkpoint54c_post (2004/07/18)
5335    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
5336      this affects (truncation error) output.txt of test-exp:
5337       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
5338    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
5339    o change Qnet to always be the net heat flux, (+upward).
5340      affects (truncation error) output of natl_box exp.: updated
5341    o define the max number of passive tracers in PTRACERS_SIZE.h
5342    o start to test mnc routinely in exp0
5343    o add sea-ice loading (sIceLoad) as a new forcing field.
5344    
5345    checkpoint54b_post (2004/07/08)
5346    o add testreport "-j JOBS" option for parallel builds (tested and pretty
5347       impressive on Altix and Opteron systems)
5348    o diagnostics can now write NetCDF files through the mnc package
5349    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
5350    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
5351    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
5352      affects (truncation error) output of lab_sea & natl_box exp.: updated
5353    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
5354    
5355    checkpoint54a_post (2004/07/06)
5356    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
5357    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
5358    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
5359    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
5360      + internal_wave (shift in writing cg2d_ini_res)
5361    checkpoint54a_pre (2004/07/05)
5362    
5363    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
5364      - modified verification/lab_sea and natl_box_adjoint accordingly
5365    
5366    checkpoint54 (2004/07/02)
5367    checkpoint53g_post (2004/07/02)
5368    o prepare splitting of thermodynamics: store convect.counter in common block
5369    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
5370      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
5371    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
5372    o new parameter "nShapS": allow to treat differently S from T (nShapT)
5373    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
5374    o restore adjointability
5375    
5376    checkpoint53f_post (2004/06/25)
5377    o modifications that affect AIM experiment results (update output.txt):
5378      - no advection of S at top interface Nr (pkg/generic_advdiff)
5379      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
5380    o AIM pkg:
5381      - include stability function into surf.Flux derivative relative to Tsurf
5382      - calculate clear-sky radiation & surface temp. change (for diagnostics)
5383    
5384    checkpoint53e_post
5385    o merged cylindrical coord configuration
5386    o added rotating_tank experiment
5387    checkpoint53e_pre
5388    
5389    checkpoint53d_post (2004/06/14)
5390    o faulks upgraded: re-generate output.txt that have changed:
5391       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
5392    o Added Bryan and Lewis, 1979, vertical diffusivity profile
5393    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
5394    o added Sadourny discretization of Coriolis
5395      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
5396      - re-enabled use of omega3 (useAbsVorticity)
5397    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
5398      vector-invariant equations
5399      - note: does *NOT* yet use same variable visc. for no-slip BC's.
5400    o recoded the lateral boundary conditions for non-hydrostatic w, this time
5401      hopefully without new bugs
5402      - still to do: biharmonic friction for non-hydrostatic w
5403    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
5404    o regenerated output for global_ocean_ebm (using -ieee)
5405    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
5406      of mom_common/
5407      - simple re-arrangement of instructions within computing loop
5408    checkpoint53d_pre (2004/05/21)
5409    
5410    checkpoint53c_post (2004/05/21)
5411    o new version of coupler for AIM+thSIce and Ocean models
5412     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
5413     - land: change Evaporation of snow
5414     - aim with thSIce: fix bug in snow-precip.
5415    o changes to calc_gw.F
5416     - bug fix for w^2 term near the bottom boundary
5417     - (hopefully) improve the lateral slip boundary condtions for use with
5418        partial/looped cells
5419      - because the bug fix changes two verification experiments anyway (exp5
5420        and plume on slope), change the lateral boundary condition from half slip
5421        to the value of no_slip_sides
5422    o ebm package wasnt quite up to the parallel task. Fixed that.
5423    o Adjoint of EBM package + verification
5424      * TLM OK
5425      * ADM not sufficient accuracy yet (needs further testing)
5426    
5427    checkpoint53b_post (2004/05/14)
5428    o Commiting new energy balance model to repository
5429      * package is pkg/ebm
5430      * verif. is verification/global_ocean_ebm
5431      * references are in ebm_driver.F
5432    C      * X. Wang, P. Stone and J. Marotzke, 1999:
5433    C        Global thermohaline circulation. Part I:
5434    C        Sensitivity to atmospheric moisture transport.

5442    C        by atmospheric eddy transports.
5443    C        J. Climate 7(12), 1870-1882
5444    o Will need long integration testing.
5445    checkpoint53b_pre (2004/05/14)
5446    
5447    o created pkg/mom_common in preparation for variable viscosity code
5448    o renamed and split ini_mnc_io
5449    o pkg/land: only liquid water can diffuse or run-off
5450    o AIM using land: soil wetness availability account for snow
5451    o added printMapIncludesZeros to EEPARMS namelist
5452    
5453    checkpoint53a_post (2004/05/11)
5454    o restore TAMC compatiility for exf_constants.h
5455      (no usage of _d in .h)
5456    o Additional storing in KPP in an attempt to fix
5457      TAMC problem with adjoint of KPP code.
5458      (no success...)
5459      Identical code works fine with TAF.
5460    o Fixed verification/natl_box_adjoint experiments.
5461      Initial conditions for Experiments 4 and 5 are now
5462      set to "SEAICE_initialHEFF=0", which is more reasonable,
5463      and hence gives results closer to that of Experiment 2.
5464      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
5465    
5466    checkpoint53 (2004/05/06)
5467    o stable checkpoint with up to date adjoint
5468      TLM tests only run for 1st grdchk at the moment. Its unclear if
5469      this is a code problem or a problem with resetting code for g_
5470      variables that is being autogenerated wrong.
5471      Otherwise:
5472       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
5473       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
5474         are both still in chaos following their security messes.
5475    
5476    checkpoint52n_post (2004/05/06)
5477    o various build (mostly genmake2) changes including:
5478      - ability to build/run more easily within Cygwin and MacOS X
5479      - more complicated Makefiles with a stronger dependence on Gnu Make
5480    o pkg/seaice modifications
5481      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
5482        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
5483        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
5484      - changed proxy for geostrophic velocity and updated
5485        verification/lab_sea/results/* accordingly
5486      - removed ADI dynamic solver from pkg/seaice
5487      - replaced all occurrences of 1/CSTICE or 1/CSUICE
5488        they caused a segmentation fault under certain circumstances
5489      - removed unused field WATR
5490    o bug fix in exf-package:
5491      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
5492         now reflect that.
5493    o small fixes in the cal-package:
5494      - set reference date to first of January for the 'model'-calendar
5495      - failing of cal_CheckDate in cal_FullDate now actually results in a
5496        warning
5497    o small modifications in exf-package to increase flexibility:
5498      - change climtempfreeze from a constant to a runtime parameter that
5499        is specified in data.exf_clim (default = -1.9)
5500      - introduce runtime parameter windstressmax (default = 2.0) that is
5501        specified in data.exf
5502    o fix in pkg/thsice:
5503      - update Evap (Tsf changes) to be consistent with Latent heat flux
5504      - maintain snow precipitation unchanged (even if Tsf >=0).
5505     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
5506    
5507    checkpoint52m_post (2004/04/18)
5508    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
5509      this does not change any of the results, because myIter=0 in swfrac always
5510      lead to jwtype=2 (the default anyway), but the call makes little sense
5511      as a default
5512    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
5513    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
5514      atmospheric model (AIM) to use it ; add a "slab ocean" component.
5515    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
5516    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
5517    o extending useSingleCpuIO option to work with new exch2 I/O format
5518      - old-style, missing-tile I/O is still accessible by defining CPP
5519        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
5520    o monitor package can write to NetCDF files and/or STDOUT
5521    o fix re-definition bug in MNC_GRID_INIT_ALL()
5522    o doc/api_reference added
5523      - a framework for building an API Reference Manual using all
5524        the "protex" comments embedded in the code
5525      - see pkg/generic_advdiff, pkg/mnc for examples
5526    o MNC:
5527      - make myThid the last argument for all subroutines
5528      - new default for the grid files: NO halos
5529      - add useMNC and other run-time flags
5530      - separate per-file-group handling of the unlimited dimension
5531      - early initialization of MNC w/ flags read at the eeboot stage
5532        and lookup tables set in initialize_fixed
5533      - write all MNC output to a freshly-created directory
5534    o thermodynamics sea-ice (thsice) is now tested with testreport.
5535    o test exp. advect_cs: use the standard cs32 grid ; update output.
5536    o Added functionality to grdchk:
5537      pick global i,j,k position (or nearest wet) where to perform check.
5538    
5539    checkpoint52l_post (2004/03/11)
5540    o new land formulation:
5541      a) use ground enthalpy as prognostic variable to ensure exact
5542         energy conservation.
5543      b) account for water temperature and for latent heat of freezing
5544         in all processes (rain, run-off, ground storage)
5545      c) compute surface and ground temperature implicitly.
5546    o aim_v23 modification for new land model:
5547      a) Treat separately land / ocean / sea-ice surface fluxes
5548         to allow implicit computation of land & sea-ice surface temp.
5549      b) add snow precipitation.
5550    checkpoint52l_pre (2004/03/11)
5551    
5552    o fix problem (when 1 tile is empty) in min/max monitor.
5553    o fix bug in timeAve (u,vZetatave in common block)
5554    o no restoring terms under ice for pkg/seaice
5555    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
5556    o bug fix for pkg/seaice pickups
5557    o change MNC call locations and add coordinate attributes
5558    o mask vorticity at the corner ; affects global_ocean.cs output
5559    o fix ini_curvilinear_grid ; test CS experiments with mpi
5560    o aim.5l_cs: modify sea-ice fraction input file ; update output
5561    o exf: Adding simple range check routine for exf fields after read
5562    
5563    checkpoint52k_post (2004/02/23)
5564    o removed top-level directory "diags"
5565      - we migrated these functions to pkg/timeave a long time ago
5566    o fixed bug introduced in pkg/monitor
5567    o accuracy ctrlprec = 32 insuffient for gradient checks using
5568      averaged fields (I/O via cost_averages)
5569      -> use ctrl.h in active_file*.F to control I/O precision.
5570    o paramter list of CALL ADTHE_MAIN_LOOP
5571    o added initial do_the_model_io to ecco
5572    o set all ...Freq to zero after cost_final
5573      taveFreq, dumpFreq, pChkptFreq
5574    o MAIN and ECCO differentiability restored
