5      ==============================      ==============================
6    
7    o pkg/autodiff:
8      - rename S/R INI_AUTODIFF to AUTODIFF_INIT_VARIA ;
9      - create new header file "AUTODIFF_PARAMS.h" for pkg/autodiff parameters
10        which are now read from new parameter file "data.autodiff" (inAdExact
11        previously in "data", use{KPP/GMRedi/SEAICE}inAdMode previously in data.pkg)
12      - add file "data.autodiff" in all verification/*/input_ad/ directories.
13      - add run-time parameter to turn On/Off SEAICEuseFREEDRIFT in adjoint/forward
14        mode (used in global_ocean.cs32x15.seaice_dynmix test exp.)
15    o verification/tutorial_tracer_adjsens/
16      - add extra sub-verification which uses "SOM" advection scheme
17        (2nd Order-Moment Advection Scheme, Prather Limiter) with
18          #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
19        and in data:
20          multiDimAdvection=.TRUE.,
21          tempAdvScheme=81,
22          saltAdvScheme=81,
23    o model/src:
24      - introduce ALLOW_BALANCE_RELAX which allow the removal
25       of the global mean of relaxation terms by setting
26       balanceThetaClimRelax and balanceSaltClimRelax
27      - disable balanceEmPmR and balanceQnet in the case when useSeaice.
28       This case is now treated appropriately in seaice_growth.F
29    o pkg/seaice:
30    - do balanceEmPmR and balanceQnet based on the net fluxes
31      (SItflux) that enter the ocean+ice system rather than QNET
32      and EMPMR. Works best in real fresh water.
33    - SIatmFW, SIatmQnet, and SItflux computations had to be moved
34      out of the diagnotics bloc, and stored in global arrays.
35    
36    checkpoint63o (2012/06/29)
37    o vertical mixing schemes:
38      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
39      - replace computation of density (in Function STATE1, opps_calc.F) by a call
40        to S/R FIND_RHO_SCALAR
41      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
42        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
43        affects output (vermix.ggl90) at truncation level.
44    o testreport:
45      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
46        (nSx,nSy) for the number of threads (from eedata.mth)
47    o model/src:
48      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
49        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
50    o verification/tutorial_tracer_adjsens/
51      - compile with ALLOW_CG2D_NSA
52      - run with nonlinFreeSurf=3
53      - update reference output_adm.txt
54    o tools/genmake2:
55      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
56        refine usePROFILES switching off (only when NetCDF is not available).
57    o verification (atmospheric set-up):
58      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
59    o pkg/profiles : refine profiles and files handling.
60    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
61    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
62      - changes to use model/src/the_main_loop.F rather than the ecco version
63        in ecco type adjoint runs.
64    o model/src:
65      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
66      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
67      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
68    o model/src:
69      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
70        update output of test experiment bottom_ctrl_5x5.
71    o pkg/generic_advdiff:
72      - implement vertical bi-harmonic diffusion (for now, only for T & S and
73        only explicitly).
74    o verification/bottom_ctrl_5x5/
75      update reference output (results changed quite some time ago,
76      not sure when; but new reference results look ok in terms of grdchk)
77    o verification/1D_ocean_ice_column/
78      For verification purposes, the exact adjoint rather than an approx.
79      should be used (e.g., to comare against F.D. or TLM).
80      removed autodiff_inadmode*_ad.F routines in code_ad/
81      Update results/ accordingly.
82    o pkg/cal:
83      - change cal_getdate.F so that output date is function of input time only
84        (less ambiguous, not mixed up with input iteration number).
85      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
86    o pkg/diagnostics:
87      - implement calendarDumps also for stats-diags
88      - implement calendarDumps also for snap-shot output (negative freq)
89      - for now, ignores calendarDumps if non-zero phase-lag.
90    
91    checkpoint63n (2012/06/04)
92    o model/src:
93      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
94        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
95      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
96        similar to calc_r_star.F); update results of experiment internal_wave and
97        tutorial_global_oce_in_p (affected @ truncation level).
98    o pkg/shelfice:
99      - add parameterisation of advective-diffusive flux into the ice shelf
100        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
101      - simply eps3/3a computation
102    o eesupp:
103     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
104       between tiles, just fill-in edges assuming locally periodic subdomain) and
105       add corresponding exchange subroutines (EXCH0);
106     - new CG-solver version (_EX0) for disconnected-tiles special case.
107    o model/src (CG-solvers):
108     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
109       (similar final residual output and max-Iter number as with standard version);
110     - allows to store and use lowest-residual solution (standard & _SR versions);
111     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
112     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
113    o eesup/src:
114     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
115       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
116    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
117    
118    checkpoint63m (2012/04/27)
119    o pkg/shelfice:
120     - account for partical cells in surface level below ice-shelf for hydrostatic
121       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
122    o ad test experiments:
123     - update and rename to "ad_optfile.local" local AD-optfile specific to a
124       particular adjoint verification experiment (in verification/*/code_ad/)
125    o pkg/seaice & pkg/exf:
126     - Part two of ECCO-CLIVAR code merges.
127       Completes merge of seaice area relax. code.
128       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
129       to be set in EXF_OPTIONS.h since this pkg controls its I/O
130       (and avoids second CPP option in SEAICE_OPTIONS.h)
131     - change default value of costIceStart & costIceEnd to a valid date.
132     - add snowPrecip to HSNOW in seaice_growth
133    o pkg/ptracers:
134     - move ptracers summary and setup check into separated S/R ; add a check for
135       valid PTRACERS_Iter0 value (error+stop or just warning).
136    o pkg/cal (+ pkg/ecco):
137     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
138       as input; and for AD, unless both are not differentiable (e.g., k index)).
139    o model/src:
140     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
141       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
142       temporary set to usingZCoords value (to be changed to F when using shelfice).
143     - hydrostatic pressure: implement partial cell near the surface also for
144       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
145       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
146    o pkg/ctrl/ctrl_init.F:
147     - add a formal parameter to s/r ctrl_init_rec to print
148       xx_$(ctrl_valiable)_file for easier debugging
149     - move call of cal_* routines into the if-block where they are really
150       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
151       to specify a startdate
152    o pkg/seaice:
153     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
154       global_ocean.cs32x15/code versions).
155     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
156       verification experiment global_ocean.cs32x15.seaice and update results.
157    o pkg/exf:
158     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
159       (according to useExfYearlyFields).
160    o pkg/cal:
161     - move calendar setting & summary (previously in cal_readparams.F) into new
162       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
163       length of the simulation is set (after SET_PARMS call); This is an attempt
164       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
165     - For safety: keep a record of pkg/cal parameter settings status
166               to allow to STOP if one pkg/cal S/R is called too early.
167     - add a stop in all basic pkg/cal subroutines if called before setting is done.
168     - modify cal_getdate.F: stop when nothing was returned;
169       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
170       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
171    
172    checkpoint63l (2012/04/04)
173    o pkg/bbl:
174      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
175        update global_with_exf output.yearly.txt file.
176    o pkg/cal:
177      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
178      - remove 2 unsused and very short (1 line only) functions ;
179      - remove unsused subroutines from AD-Diff list.
180    o model/src:
181      - start to implement clean wait to stop in initialization S/R (config_check.F,
182         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
183    o folowing PRINT_MESSAGE changes:
184      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
185    o pkg/bbl:
186      - modification so it can work with z*
187      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
188      - global_with_exf/input.yearly verification; changes output.yearly.txt
189    o eesupp/src:
190      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
191        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
192      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
193        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
194      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
195      - when using MPI, always set usingMPI=T ; set default accordingly and stop
196        if not consistent.
197      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
198        argument is zero (in case called within single-thread section).
199    o pkg/fizhi:
200        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
201        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
202    o pkg/exch2:
203      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
204        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
205      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
206        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
207        with bad ones coming from a not-yet-updated halo.
208        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
209    o pkg/frazil:
210        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
211        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
212    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
213    o verification/lab_sea
214      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
215      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
216      * nTimeSteps 3 -> 4
217      * changed reference output accordingly
218    o pkg/ctrl:
219      * fix ctrl_get_gen for xx_sst, xx_sss
220    o pkg/fizhi:
221      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
222        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
223      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
224        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
225        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
226    o pkg/gmredi:
227      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
228    o pkg/fizhi:
229      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
230        (old)aces open64 tuv test.
231    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
232    o pkg/mom_vecinv:
233      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
234        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
235        with non-lin free-surf).
236    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
237      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
238      some compilers (gfortran 4.6.0 on MacOS)
239    o momentum:
240      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
241        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
242        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
243    
244    checkpoint63k (2012/03/17)
245    o model/src:
246       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
247         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
248       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
249         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
250    o model/src: solve_*diagonal.F
251       - replace division with multiplication by inverse (similar to original version)
252         update output of AD exp. global_ocean.90x40x15.
253       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
254         to enable the use of the vectorized & differentiable solve_tridiagonal.F
255       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
256         vertical advection (to get solve_tridiagonal tested in AD mode).
257    o pkg/seaice: ECCO-CLIVAR merge:
258      1. seaice AREA relaxation
259         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
260         * runtime flag: SEAICE_tauAreaObsRelax
261      2. modified global mean cost imbalance code: CPP option
262          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
263    o another iteration on solve_*diagonal.F
264       Make choices independent of AUTODIFF
265       Default will be the adjoinable vectorized version.
266       Alternative choices are:
267       * non-adjoinable original version with low memory footprint:
268         #define SOLVE_DIAGONAL_LOWMEMORY
269       * still adjoinable but does not vectorize (k as inner-most loop):
270         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
271    o testreport
272     - add option to use a home made wrapper around "make"
273     - remove MITGCM_IEEE env. variable (no longer active)
274    o pkg/shelfice
275     - improve computation of friction velocity for velocity dependent
276       exchange coefficients: include velocities into SHELFICEBoundaryLayer
277       block to average velocities vertically
278     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
279    o Modify diagonal solvers, now three versions (upon request):
280      #ifndef SOLVE_DIAGONAL_AUTODIFF
281        1. default version (dating back a while ago)
282      #else /* def SOLVE_DIAGONAL_AUTODIFF */
283      # ifdef SOLVE_DIAGONAL_KINNER
284        2. adjoinable version with k-innermost loop (G. Forget)
285      # else
286        3. adjoinable vectorized version of 2.
287      # endif
288      #endif /* SOLVE_DIAGONAL_AUTODIFF */
289      All flags are currently set within routines, but could/should be moved to CPP-options.
290      Array bounds for 1. are as before, for 2.,3. cover the entire domain
291      (could be changed for 1. too).
292    o verification/lab_sea (fwd):
293      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
294        use 7 categories (except hb87), new solve4temp params (except salt_plume),
295        constant salinity (=4) or variable salinity (salt_plume) done through
296        SItracer.
297    o pkg/seaice:
298      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
299      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
300         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
301        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
302        SEAICE_freeze got retired) but already better than previously with
303        SEAICE_freeze=123456.7 deg.C;
304      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
305        (safer multi-threaded setting); always set SEAICEuseEVP;
306      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
307        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
308        stop if multiple specifications for the same coeff; make sure default
309        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
310    o pkg/obcs:
311      - allow to switch to upwind 1rst order advection scheme for the advective
312        flux computation at the open-boundary; disabled for adjoint built.
313    o pkg/ptracers:
314      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
315      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
316      - add parameter to decide when to start a tracer; use internal flag to
317        know which tracer to step-forward; switch this internal flag at the top
318        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
319        for adjoint built.
320    o pkg/seaice:
321      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
322      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
323      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
324    o pkg/ecco:
325      - fix writing of output file DiagnosCost_ClimSalt/Theta
326        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
327    o pkg/seaice:
328      - add missing initialisation of COR_ICE array in dynsolver.F
329      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
330        compiled either way, and is tested in all exps (multidim was only tested
331        in lab_sea ad before).
332      - cosmetic change to prepare for future addition of ITD. no change to results.
333        no defaults change.
334      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
335      - by lack of adequate verification experiments, I further used custom versions
336        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
337        should be correct.
338      - avoid recomputations in ad.
339    o array initialisation in adjoint mode:
340      1) pkg/mom_common/mom_calc_ke.F:
341        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
342        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
343        part this initialisation is gone, resulting in Floating Point Exception
344        (caught by open64 compiler with debug option).
345      2) model/src/convective_weights.F
346        set output convectCount over the full array range (instead of doing
347        an update): this fix a similar issue when called within recomputation (adjoint)
348        which could by-pass the initialisation (normally done in the caller S/R).
349    o pkg/seaice:
350      - final version of turbulent flux params, as agreed at MIT ice meet:
351           SEAICE_mcPheePiston (default is ~ 0.000875)
352           SEAICE_mcPheeTaper (default is 0.)
353           SEAICE_frazilFrac (defualt is 1.)
354           SEAICE_mcPheeStepFunc (default is false)
355      - changes results at trunction error level
356      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
357    o added pkg/frazil:
358      - see frazil_description.tex for details
359      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
360    o pkg/shelfice/shelfice_thermodynamics.F
361      - fix exponents for velocity dependent exchange coefficients: change
362        from 2/3(=0) to 0.66666666666666667
363      - move computation of velocity dependent exchange coefficients into
364        separate loop, so that it applies to both thermodynamics
365      - move some divisions by constants out of loops
366    
367    checkpoint63j (2012/02/16)
368    o pkg/seaice:
369      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
370      - SItracer:  added run time params, and allow coupling to ocn salinity.
371    o pkg/seaice: remove (almost) all divisions by constants within loops
372      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
373      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
374      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
375      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
376    o pkg/seaice :
377      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
378        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
379      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
380      - add permanent SItflux diag that corresponds to TFLUX but includes
381        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
382      - allow activation/testing of a fix for suspected missing term in
383        ocn-ice heat budget (to be confirmed). To test this, you want to
384        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
385        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
386      - no change in results, fwd or ad.
387    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
388      - switch to variable freezing point.
389           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
390      - bug fix : the sublimation term that was missing is now activated.
391           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
392      - bug fix : flooding sign term for SIsal0.NE.0.
393           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
394    o pkg/seaice:
395      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
396        is now the default, and the old default constant freezing point is recovered
397        with SEAICE_tempFrz0    = -1.96,
398             SEAICE_dTempFrz_dS = 0.,
399      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
400      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
401      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
402        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
403      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
404        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
405      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
406        seaice_growth r149 for legacy branch (no results change).
407      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
408        from I. Fenty).
409      - results did not change except for global_ocean.cs32x15, mostly due to the
410        switch to variable freezing point (see above item for detail).
411    o pkg/thsice:
412      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
413        seawater freezing in thsice_calc_thickn (not used).
414    o pkg/seaice: turbulent flux term specification via run time params.
415      - replace CPP switches with run time switches to facilitate testing
416      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
417                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
418      - added runtime parameter : SEAICEturbFluxFormula
419      - move Mcphee constants to SEAICE_PARAMS.h
420      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
421                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
422                 remove seaice_summary call (moved to seaice_init_fixed)
423      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
424        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
425      - seaice_summary.F : add missing report of read turbulent flux term set up
426                           and SITRACER.
427      - seaice_check.F : check range; inform and stop if retired CPPs are used
428                         (incl. SEAICE_AGE).
429      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
430             CPP switch, same computation as before for the different options.
431      - change results at the truncation level.
432    o pkg/seaice:
433      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
434        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
435        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
436      - update verification/*/input*/data.seaice:
437        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
438        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
439        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
440        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
441    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
442      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
443        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
444        difference in results only due to machine truncation.
445      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
446        MaykutPolySatVap; keep MIN_LWDOWN.
447      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
448      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
449        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
450    o pkg/salt_plume:
451      - isolate saltPlumeFlux array exch into a specific S/R called from
452        do_oceanic_phys.F
453      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
454    o verification:
455      - move untested set-up to MITgcm_contrib/verification_other.
456    o pkg/seaice:
457      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
458    o pkg/seaice:
459      - seaice_solve4temp.F (keeping results unchanged):
460        * add 2 future run-time params to select which saturation vapor pressure
461          formula is used and how post-iteration fluxes are set.
462          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
463        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
464          the linearized expression to stay consistent with tsurf finding.
465      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
466        can be < 0.
467    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
468      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
469        conductive heat flux F_c , and add it explicitly when updating tsurf as
470        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
471        so that now F_ia has a consistent meaning through the entire routine.
472        This causes differences at truncation level: update output of fwd exp.
473        global_ocean.cs32x15.seaice.
474    o pkg/seaice:
475      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
476        of arrays, sign/direction of fluxes; no effect on results.
477      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
478        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
479        note: this should have been done before changing celsius2K default.
480      - to keep results unchanged, add back old value of celsius2K in verification
481        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
482      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
483        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
484        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
485        freezing temp is consistent with value in seaice_growth.F ; this causes
486        differences at machine truncation level: update lab_sea AD output (3/4).
487    o pkg/seaice:
488      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
489        and climsst/sss even when using seaice (to prevent calculation that might
490        use SST on land); does not affect any verification exp.
491      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
492        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
493    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
494      over land (non-legacy code)
495    o vectorize salt_plume package:
496      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
497      - this code computes plumebk everywhere (also over land), thus requires
498        code to avoid divisions by zero and catch the case of kLev=Nr.
499      - efficiency of salt_plume_frac is still sub-optimal
500    o tools (genmake2):
501      - fix makefile NAME specification (option: -makefile NAME) by adding
502        "-f $MAKEFILE" in few places where it was missing including makedepend
503        command (contribution from Paul).
504    
505    checkpoint63i (2012/01/24)
506    o model/src:
507      - add factorized versions of some EOS code to find_rho.F,
508        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
509    o model/src:
510      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
511      - change default celsius2K from 273.16 to 273.15
512      - to keep results unchanged, add back old value of celsius2K in verification
513        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
514         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
515    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
516      to make TAF generate vectorizable code
517    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
518       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
519       have flags that do this more efficiently.
520    o pkg/diagnostics/diagstats_calc.F
521      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
522    o pkg/obcs (with exch2):
523      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
524        and remove code (in obcs_readparms.F) which was based on EXCH of indices
525        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
526    o pkg/exf and seaice exp:
527      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
528        so that switching off area & heff advection flags does not affect results.
529      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
530      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
531        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
532        results of verification experiments: 1D_ocean_ice_column(fwd),
533        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
534        and offline_exf_seaice (all 4).
535    o pkg/seaice:
536      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
537        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
538      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
539        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
540        not multi-dim advection;
541      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
542        SHORTWAVE_HEATING #undef.
543    o optim: make Makefile more robust (?)
544    o pkg/obcs:
545      * fix treatment of obcs_read_pickup for TAF
546    o pkg/shelfice:
547      * add missing initialisation of num_shifwflx
548      * new adjoint verification exp. for isomip
549      * change Prandtl and Schmidt numbers from generic formulations
550        (in terms of model diffus. and visc.) to separate runtime
551        parameters, with Holland and Jenkins (1999) default values.
552    o pkg/exf (interpolation):
553      - extended input field (2 rows) near the N & S poles:
554        * fill in with the symetric value (when even Nb of data in longitude)
555        * add average value at the poles only for scalar quantities ; for vector
556          component interpolation, skip the averaging and keep duplicated values,
557          unless the 2 components have same location (uvInterp=T) in which case
558          interpolate the 2 components together using S/R EXF_INTERP_UV.
559      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
560        together: this allows to account properly for local orientation when
561        averaging at N & S pole.
562      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
563        exf-interpolation near N & S poles. Undef by default.
564      - add debug check/print on 1rst iter if debugLevel >=2.
565    o pkg/exf:
566      - change masking flags definition (no longer "parameter"), put them in
567        common block and set them in S/R EXF_INIT_FIXED.
568      - change recognized masking flag from s,u,v to c,w,s since the mask
569        to use (maskC,W,S) depends on position on model grid and has little to
570        do with scalar/vector difference; fix masking if using P-coordinates.
571      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
572        and update results of exp. global_with_exf (x2).
573      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
574    o pkg/obcs
575      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
576    o pkg/exf (interpolation):
577      - assume periodicity in X only if input field cover full longitude range.
578      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
579        and should vectorise).
580      - fix input lat of the 2 added row (in case we provide N.pole data).
581    
582    checkpoint63h (2011/12/30)
583    o pkg/seaice:
584      - change declaration of UVM from _RL to _RS in order to get B-grid
585        uIce,vIce monitor when _RS = real*4
586    o pkg/offline:
587      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
588      - compute vertical velocity if not read from file (switch on exactConserv
589        & staggerTimeStep);
590      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
591    o verification:
592      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
593        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
594        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
595      - update output of exp. global_ocean.cs32x15.viscA4 after changing
596        grid-file angles (used here for coriolis-3d);
597      - remove (or gzip) few files not needed to run fizhi-cs experiments.
598    o pkg/exf (vector interpolation):
599      - rotate vector component toward local grid-axis orientation using grid-angles
600        (stored in GRID.h) instead of locally computed rotation angle; keep old code
601        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
602    o pkg/seaice:
603      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
604        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
605    o pkg/PKG_OPTIONS.h files:
606      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
607        outside of the #ifdef ALLOW_THISPKG / #endif block.
608      - update verification/*/code/PKG_OPTIONS.h files.
609    o add a verification experiment (offline_exf_seaice/input.seaice) that test
610      the B-grid LSOR solver
611    o pkg/seaice: sort out emissivity and long wave radiation step 2:
612      - add emissivity for snow and ice as new run-time parameters
613        (unfortunately) that default to the corresponding exf values; this
614        changes results in most verification experiments so that for backward
615        compatibility these parameter have to be set explicitly to inconsistent
616        values (ugly);
617      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
618        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
619        until we agree how to handle this bug properly
620    o pkg/exf (interpolation):
621      - add a set of run-time param ({inputfield}_interpMethod), one for
622        each interpolated input field, to select the interpolation method
623        with a value of zero switching off the interpolation;
624      - print interpolation parameters to standard output;
625      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
626        (to use instead runoff_interpMethod=0 in data.exf).
627      - simplify default setting of interpolation parameters (for all fields,
628        set position to match model grid cell-center position, leading to trivial
629        interpolation in case of regular Lat-Lon grid) and fix for the case of
630        non-uniform delY.
631    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
632       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
633       this factor is absolutely required, because the lw exitance (= out-going
634       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
635       where the reflectivity rho = 1-emissivity for conservation reasons. Once
636       this is established, we can remove the CPP-Flag (if we want to).
637    o pkg/seaice:
638      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
639        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
640      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
641        what the name implies (and not emissivity*BoltzmannConstant), this means
642        the old default value of 5.5e-8 now means
643        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
644        S/R exf_readparms
645      - FV-discretization of the B-grid LSOR solver, turn on with
646        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
647        of the calling routine dynsolver, so that B and C-grid code look a
648        little more alike.
649      - fix index bugs in ostres.F (B-grid code)
650    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
651    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
652      default for SEAICE_emissivity, if useEXF; requires setting a wrong
653      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
654      backward compatiblity
655    o model/src: use sigmaR in calc_ivdc
656    
657    checkpoint63g (2011/12/16)
658    o pkg/seaice/seaice_growth.F:
659      fix heat conservation of the coupled ocean-seaice system.
660      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
661      solid vs liquid water treatment is resolved via QNET.
662    o pkg/seaice/seaice_growth.F:
663      add missing term for sublimation in saltFlux, which was breaking conservation.
664    o pkg/seaice/seaice_model.F:
665      Remove this patholigical case treatment in evolution branch,
666      where it is un-necessary and breaks conservation.
667      Update global_ocean.cs32x15/results accordingly for
668      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
669    o model/src:
670      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
671      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
672    o pkg/obcs:
673      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
674      tendency for temperature and salinity that is then applied to update
675      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
676      horizontal advection and diffusion contributions on the boundary (in
677      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
678      removing the mask in S/R timestep_tracer. The advantage of this approach is
679      that the updated tracer values include contributions from the surface
680      forcing and vertical diffusion.
681      This modification changes exp4.stevens because of vertical diffusion.
682    o model/src:
683      change non-curvilinear grid setting to also work with exch2 + blank tiles:
684      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
685        face dimensions.
686      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
687        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
688        and INI_SPHERICAL_POLAR_GRID.
689      change test-experiment global_ocean.90x40x15:
690      - split the domain in many more tiles (9x4 tiles of 10x10 each);
691      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
692      - update results of both test (std & dwnslp).
693    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
694       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
695    o model/src:
696      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
697        and fix initialisation when using sigma-coords.
698    o model/src:
699     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
700       to their current value at the beginning of forward_step.F": add a new run-time
701       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
702     - set doResetHFactors=T in the following test exp:
703        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
704        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
705        and tutorial_global_oce_in_p (nonLinFS in p)
706    o pkg/ecco
707      - added IES cost term
708    o verification/advect_xz
709      - scale down the depth by 1/100 (from 200 km to just 2.km)
710      - add secondary test using divergent flow, r-star and implicit vertical advection.
711      - add note (check_conserve_TS.txt) and matlab script to check global
712        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
713    o pkg/rbcs:
714      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
715    o pkg/obcs (Stevens BCs):
716      - fix various problems in the phase speed computations of the Stevens
717        boundary conditions:
718        - sign error for western and southern boundaries,
719        - time tendencies were underestimated by factor of dTracerLev and some just
720          zero (for multidim advection schemes) -> now estimate time tendencies
721          from difference between previous (n) time level and the one before (n-1);
722          this requires storing a field per tracer per boundary, also in the pickup
723          files.
724        - replace deltaTmom in cflMer/Zon computation with dTracerLev
725        - set default phase velocity to cflMer/Zon
726      - update verification experiment exp4.stevens
727    o pkg/generic_advdiff (implicit_r):
728      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
729        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
730      - fix implicit vertical diffusion or advection with NonLin FreeSurf
731        (was using current recip_hFacC instead of future recip_hFacC): set future
732        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
733        solver S/R ;
734      - fill diagnostics of vertical advective fluxes (computed from tendency)
735        when using implicit vert. advection;
736      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
737         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
738         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
739         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
740    o pkg/diagnostics:
741      - add diags for T & S tendency which goes through Adams-Bashforth.
742    
743    checkpoint63f (2011/11/30)
744    o pkg/obcs/obcs_calc_stevens.F:
745      - join some loops to reduce number of if-statements
746      - fix a bug in code for northern and southern boundaries.
747    o pkg/seaice/seaice_init_varia.F
748      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
749        caused zero ice-velocities for the B-grid code
750    o pkg/seaice/seaice_init_fixed.F
751      - fix a bug in the initialisation of the second metric terms
752        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
753      - this affects all seaice configurations with useCurviLinearGrid = .true.
754        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
755        = .true. (default)
756      - the only verification experiment affected is global_ocean.cs32x15:
757        icedyn, seaice, and seaice_dynmix (AD)
758    o pkg/thsice/thsice_diagnostics_state.F
759      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
760        not contain garbage that can lead to surprises in diagstats_calc.F
761    o model/src:
762      - move bi,bj loops inside INTEGR_CONTINUITY ;
763      - call INTEGR_CONTINUITY directly from forward_step.F
764        (previously called from momentum_correction_step.F)
765      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
766        forward_step.F and pkg/ecco/the_main_loop.F
767    o model/src/do_oceanic_phys.F:
768      - reset addMass to zero only if useICEFRONT ;
769      - separated k-loop for rhoInSitu calculation ;
770      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
771        and at constant T,S (= WdRHOdP);
772      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
773        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
774        transport of locally-referenced potential density);
775        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
776    o gluemnc:
777      - replace ncrcat with ncks when adding variables to *.glob.nc
778      - change the way variables without record dimensions are handled so that
779        files that have variables with and without record variables can be glued:
780        add a record dimension with a new unique name to be able to differentiate
781        between variable with and without a-prior record dimensions. Remove
782        this record dimension before adding the variable to the *.glob.nc file.
783        This procedure automatically works also for grid.*.nc files that do not
784        have any record dimension.
785    o verification/cpl_aim+ocn:
786      - generate new reference output on baudelaire (gfortran, mpich2) (previously
787        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
788    o pkg/obcs/obcs_calc_stevens.F:
789      - add code for northern and southern boundaries.
790      - reorder some loops to save some operations and so that drFBar can be scalar
791    o model/src:
792      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
793        truncation) and add diagnostics for Adams-Bashforth tendency increment.
794      - update test-exp. AD output:
795        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
796      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
797        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
798        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
799        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
800        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
801        tutorial_plume_on_slope.
802    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
803      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
804      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
805      does not even come with an F77 compiler anymore, this should not be
806      a limitation
807    
808    checkpoint63e (2011/11/06)
809    o pkg/seaice adjoint of LSR:
810      - substantially rework STORE dirs.
811      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
812        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
813        and only perform SOLV_MAX_FIXED adjoint iters.
814        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
815        always goes to same record, meaning that the last forward field will be
816        the one used in the adjoint - an approximation.
817      - now produces non-zero LSR-related gradients, and acceptable gradients for
818        An's zonal (x-z) test case (to be checked in)
819      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
820        (but these are screwed up by the thermodynamics in the first place);
821        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
822        output_adm.txt also reflects changes to seaice_lsr
823      - global_ocean.cs32x15:
824        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
825          (output_adm.seaice.txt was updated)
826        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
827          (output_adm.seaice_dynmix.txt)
828    o test-exp. exp4+stevens:
829      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
830    o pkg/seaice (lsr solver):
831      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
832        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
833      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
834      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
835        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
836      - compute (with new S/R) and print initial (+ free-driff sol. if available)
837        and final residual of linearised system.
838    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
839      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
840    o pkg/obcs: Stevens BCs (still only for east and west)
841      - fix Stevens BCs by using intermediate velocities of previous
842        time step as "baroclinic" contribution rather velocity of one grid cell
843        inside the boundaries; more consistent but makes the entire treatment
844        more complicated, requires new pickup files and two new S/Rs:
845        obcs_copy_uv_n and obcs_save_uv_n
846        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
847        (undefined by default)
848      - silently move computation of some grid factors into separate loops to
849        save some recomputations
850      - add a hack for non-linear free surface
851      - add a verification experiment to exp4 that tests this code
852    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
853    
854    checkpoint63d (2011/10/25)
855    o pkg/obcs + seaice-dynamics:
856      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
857        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
858        values (consistent with an implicit method).
859      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
860        return to older implementation (same results as before); note that none of
861        the "experimental" OBCS_SEAICE options are implemented in the new version.
862      - switch test exp. seaice_obcs to use new version (update output).
863    o pkg/seaice:
864      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
865      - add parenthesis in Water-Ice drag calculations (evp & lsr);
866      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
867        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
868      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
869        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
870    o pkg/layers:
871      - Include potential density as new coordinate (Thanks to David Munday)
872    o pkg/dic:
873      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
874        carbonate computation/output to CALC_PCO2_APPROX
875    o pkg/generic_advdiff
876      - make TAF generate code that vectorizes:
877        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
878    o model/src:
879      - improve vectorization also for adjoint code of
880        solve_tridiagonal and solve_pentadiagonal. As this requires up to
881        5 new 3D-fields, this code is only turned on for the combination of
882        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
883        for singular matrix check (only for TARGET_NEC_SX).
884      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
885        ALLOW_AUTODIFF. This flag now needs to be set outside of
886        solve_tri/pentadiagonal.F
887    o pkg/exf:
888      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
889        optional namelist EXF_NML_OBCS).
890      - add many debug-print (to trace down where pkg/cal error msg comes from)
891    o pkg/mom_vecinv/mom_vi_hdissip.F
892      - rearrange loops so that vectorization is improved and in particular
893        the adjoint routine vectorizes. The code is a little longer now, but I
894        think easier to read.
895        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
896    o pkg/seaice:
897      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
898    o pkg/exch2:
899      - alternative code (without tile x tile matrix) for cumulated (global) sum;
900        used as default; keep using matrix version in adjustment.cs-32x32x1.
901    o tools/build_options:
902      - after merging some MPI and/or multi-threads specific optfiles so that
903        the modified default optfile support both built (using genmake2 -mpi
904        for the MPI built, using genmake2 -omp for OpenMP built),
905        move now obsolete optfiles to tools/build_options/unsupported/
906       (add copy of email sent to support list in doc/optfiles_changes.txt)
907    
908    checkpoint63c (2011/09/28)
909    o pkg/ebm:
910      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
911        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
912    o pkg/seaice (SItracer pickup)
913    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
914      To be done:
915      - thorough testing of missing fields in S/R seaice_read_pickup
916      - thorough matching between generic tracers and specific fields used
917        (e.g. volume-weighted age, area-weighted age, salinity, ...)
918    o pkg/grdchk:
919      - all procs calculate and print finite-difference gradient (for testreport)
920      - change description output used by testreport;
921      - AD testing: also compare and report Finite-difference gradient;
922        => update all output_adm*.txt
923    o test exp. global_ocean_ebm:
924      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
925        and turn on exactConserve; update (fwd) output.
926    o pkg/seaice (LSR):
927      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
928      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
929        * identical results with non-CS topology (but save up to half of EXCH calls)
930        * no much changes in cs-32 verification tests since no ice at face edges
931         (differences due to convergence criteria, since nb of iterations changed)
932        * expect some differences on lat-lon-cap grid.
933        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
934    o pkg/exch2:
935      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
936        many tiles); until alternative coding is added, just add a stop.
937    o pkg/kpp:
938      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
939        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
940    o optfiles:
941      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
942        into corresponding standard one, which now support different build:
943        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
944      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
945    o pkg/obcs (seaice):
946      - add missing EXCH for uIce,vIce after applying OBCS;
947      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
948        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
949        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
950      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
951      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
952        and eedata.mth for MPI and mutlti-threaded testing.
953    o pkg/flt:
954      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
955      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
956      - fix pickup and trajectories + profiles output with multi-threads;
957      - add parameter to select group of fields to write along trajectory and
958        profile (default unchanged);
959      - only call PORT_RAND* function when flt_noise <> 0;
960      - add multi-threaded test for verification exp. flt_example.
961    o eesupp/src:
962      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
963      - USE_OMP_THREADING: check that number of threads (from eedata) matches
964        actual number (from env.var. setting).
965    o pkg/ebm:
966      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
967      - add multi-threaded test for verification exp. global_ocean_ebm
968    
969    checkpoint63b (2011/08/29)
970    o pkg/ebm:
971      - fix sign of runoff;
972      - update directly forcing fields (Qnet,EmPmR) to use standard
973        external_forcing_surf.F (remove ebm_forcing_surf.F);
974      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
975      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
976        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
977      - update global_ocean_ebm parameters file data and update output (fwd+ad).
978    o verification/matrix_example:
979      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
980        MPI and mutlti-threaded testing.
981    o pkg/matrix:
982      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
983      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
984      - fix for multi-threaded (remove DATA statement);
985      - use standard DIFFERENT_MULTIPLE function;
986      - add MATRIX_OPTIONS.h
987    o verification/matrix_example:
988       To allow to split the domain in several tiles, change the domain size
989        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
990        Western side) of land points.
991    o (*_)write_pickup:
992      - fix few bugs in mypackage_read/write_pickup.F
993      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
994        array of length 1 (was caught by compiler syntax-check).
995    o pkg/diagnostics (velocity potential solver):
996      - fix initialisation of main diagonal matrix (for overlap values)
997    o tools/build_options:
998      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
999        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
1000      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
1001        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
1002        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
1003        and use "-devel" testreport option for standard testing on baudelaire.
1004    o pkg/grdchk:
1005      - Assume that all gradient-check position are within the same tile
1006        corresponding to global indices (iGloTile,jGloTile) and that
1007        positions (i,j indices or nbeg) are local to this tile;
1008      - set tile local-indices and proc. number according to tile global-indices;
1009      - remove grdchkwhichproc from namelist (retired param);
1010      - send adjoint gradient to all procs so that all procs print it to STDOUT;
1011      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
1012    o adding package bbl (Bottom Boundary Layer)
1013      description in MITgcm/pkg/bbl/bbl_description.tex
1014      example/test experiment in MITgcm_contrib/bbl
1015    o adjoint verifications
1016      - changed 5 experiments to multi-tiles
1017        * global_ocean.90x40x15
1018        * obcs_ctrl
1019        * offline_exf_seaice
1020        * tutorial_dic_adjoffline
1021        * tutorial_tracer_adjsens
1022        changed reference output for those that crossed tile boundaries
1023        (changed choices of gradient check positions)
1024      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
1025      - temporary bug fix in grdchk_loc.F for obcs
1026    o genmake2 & testreport
1027      - add target "obj" (just for OBJFILES files) to Makefile;
1028      - add option to specify FEXTRAFLAGS on command line.
1029    o pkg/mypackage:
1030      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
1031    
1032    checkpoint63a (2011/08/02)
1033    o pkg/diagnostics (velocity potential):
1034      - fix velocity-potential calculation when using OBCS: balance net inflow
1035        at each level (new S/R OBCS_DIAG_BALANCE).
1036      - fix some of the problems with OBCS in stream-function calculation.
1037    o pkg/exf/exf_readparms.F
1038      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
1039        EXF_NML_OBCS) more consistent, so that you need not have these lists
1040        in data.exf when they are not used.
1041    o optim/optim_readdata.F:
1042      - add some output about obcs variables that might help debugging
1043      - add a check about nvarlength
1044    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
1045    o pkg/diagnostics (velocity potential):
1046      - fix mask for OBCS (still problems in stream-function with OBCS);
1047      - add specific parameter (default = main code CG2D params) for solver;
1048      - in case of poor convergence, use solution corresponding to lowest residual.
1049    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
1050      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
1051      and should be avoided where possible.
1052    o model/src (rStar):
1053      - include r* effect on reference-state (PhiRef) in totPhiHyd
1054        (so that it's really the potential anomaly at the cell center);
1055        affect solution only if z* with full pressure in EOS.
1056      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
1057        update output (because of z* in totPhiHyd and viscA4 changes);
1058      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
1059        @ constant r) until interpolation at constant r is implemented.
1060    o pkg/diagnostics
1061      - fix RCENTER diagnostics in case cell center is not at interface middle
1062    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
1063      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
1064      that THETA and SALT are "conservative temperature" and "absolute
1065      salinity"
1066    o pkg/ctrl
1067      - fix computation of endrec in s/r ctrl_init_rec
1068      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
1069    o pkg/seaice/seaice_growth.F
1070      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
1071        remove then obsolete STORE directives
1072      - fix STORE directives for tice and tices, so that only the
1073        appropriate part of the fields are stored (and not the entire
1074        field); update global_ocean.cs32x15.seaice AD output.
1075      - cosmetic changes: adjust CPP flags and indentation for better
1076        legibilty
1077    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
1078      Chris Wilson)
1079    o pkg/gmredi:
1080       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
1081       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
1082    
1083    checkpoint63  (2011/07/11)
1084    o pkg/exch2:
1085     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
1086     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
1087       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
1088       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
1089    o pkg/diagnostics:
1090     - deal with pairs of post-processed diags which are computed together; in
1091       particular, re-order list of diags within 1 file to save 2nd computation.
1092     - add S/R to compute velocity stream-function (called after velocity-potential
1093       calculation) from divergence free transport -> new diagnostics "PsiVEL".
1094     - add parameter to select grid-point location where PsiVEL == 0.
1095    o eesupp/src:
1096       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
1097       (specific S/R needed with exch2 topology - for now, just print an error msg)
1098    o pkg/shelfice
1099     - Implement friction velocity-dependent transfer coefficients following
1100       Holland and Jenkins, JPO, 1999
1101       Original code by M. Losch with small modifs.
1102       Enable with CPP option SHI_ALLOW_GAMMAFRICT
1103       and runtime flag SHELFICEuseGammaFrict
1104    o verification lab_sea & global_ocean.cs32x15:
1105     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
1106       does not miss some dependencies (but is slower) and also works with many files
1107       (default makedepend limitation for AD built).
1108     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
1109    o pkg/diagnostics:
1110     - add run-time parameter "useMissingValue" (def=False) to fill land-point
1111        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
1112       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
1113     - Extend the use of "missing_value" setting from data.diagnostics for the case
1114       of counter-diagnostics (where fraction-weight is zero). This applies both to
1115       MNC and MDS output files.
1116    o pkg/seaice/seaice_growth.F:
1117      - add 'a priori' cap of latent heat flux based on actual mass considerations
1118        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
1119        non-legacy seaice_solve4temp.
1120      - add diagnostic of the residual sublimation freshwater flux (the freshwater
1121        flux taken from the ocean if the total actual latent heat fluxes exceed
1122        the maximum)
1123      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
1124       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
1125      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
1126       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
1127      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
1128      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
1129    o verification 1D_ocean_ice_column:
1130       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
1131       update results
1132    o pkg/diagnostics:
1133     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
1134       which are not filled-up but computed from other diags ; In this case, the mate
1135       diag points to the primary (filled-up) diag to used for post processing.
1136     - Update Velocity-potential computation using post-processed diag framework.
1137     ==> Change the ordering of fields and time-periods in MDS output file
1138       when using periodic averaging: now writes one time record with the full set
1139       of fields for this time period, then the next time reccord (it used to be
1140       one field with the full set of time records then the next field).
1141         Note: this is now similar to NetCDF (MNC) output file. <==
1142    
1143    checkpoint62z (2011/06/21)
1144    o adjoint monitor:
1145     - Add adjoint monitor output for packages exf, seaice
1146       and update relevant testreport output
1147    o pkg/seaice:
1148     - re-order diags inits so that they appear in order in available_diagnostics.log
1149     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
1150       area/heff/hsnow preceeding thermodynamic growth/melt.
1151     - modified diag: SIdA; output actual effect, as the description states.
1152     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
1153     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
1154       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
1155        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
1156     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
1157     - added diagnostics for seaice generic tracers (SItr*).
1158     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
1159     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
1160     I. Fenty: 18-Jun-2011:
1161     Minor changes to seaice package:
1162     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
1163        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
1164       - Differentiated "regularization variables" from "floor variables"
1165        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
1166        * hiceMin became SEAICE_hice_reg (old hiceMin)
1167          (with _reg meaning regularization variable)
1168       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
1169        so as to ensure energy conservation when going between phases
1170      - A22 was not used anywhere
1171     2) Changed regularization procedure for heffActual and hsnowActual to ensure
1172        well-boundedness and smooth adjoint in seaice_growth.F
1173     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
1174        because the old regularization always set heffActual >= 0.05 cm
1175     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
1176        on AREA when HEFF > 0.
1177      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
1178        requiring that DISABLE_AREA_FLOOR *not* be defined
1179     Affected verifications:
1180      - 1D_ocean_ice_column (output.txt output_adm.txt)
1181      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
1182    o pkg/diagnostics:
1183      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
1184      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
1185        (was _RL, now integer) with option = 0 to retrieve all levels.
1186      - add pieces of code to compute velocity potential at each level (new diagnostics
1187        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
1188        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
1189      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
1190        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
1191        and in diagnostics_fract_fill.F (do not need a valid pointer for the
1192        diagnostics counter-mate); check that definition of counter-diagnostic
1193        includes a valid counter-mate (in diagnostics_set_levels.F).
1194    o model/src (rStar):
1195      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
1196        affect solution only if z* with full pressure in EOS;
1197        update output of test-exp global_ocean.90x40x15.
1198    o pkg/seaice:
1199      - introduce siEps=1e-5 parameter
1200      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
1201      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
1202      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
1203        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
1204        as well as ice cover age and ridging index (attached to AREA).
1205        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
1206        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
1207        Up to SItrMaxNum=3 tracers can be used simultaneously.
1208    o pkg/salt_plume:
1209      -introduce SPsalFRAC run time parameter that sets the fraction of the
1210       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
1211       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
1212    o model debug options:
1213      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
1214        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
1215      - Refine debug-msg printing selection (3 new levels):
1216        debugMode  : controls printing of debug messages (sequence of S/R calls).
1217        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
1218         debLevZero =  0 ; /* level of disabled aux. msg printing */
1219         debLevA =  1 ; /* level of minimum  aux. msg printing */
1220         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
1221         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
1222         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
1223         debLevE =  5 ; /* level of extensive debug printing */
1224        New debugLevel default: with default debugMode value (=F),
1225          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
1226          and if debugMode=T, default debugLevel = 4 (debLevD).
1227        Relation with previous settings:
1228         debLevB (=2) corresponds to former debLevA (=1)
1229         debLevD (=4) corresponds to former debLevB (=2)
1230        Note:
1231         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
1232         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
1233            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
1234      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
1235        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
1236    o pkg/obcs:
1237      - change OBCSfixTopo default from True to False (should not change the results);
1238        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
1239    o pkg/thsice:
1240      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
1241        2nd layer seaice sublimation (unlikely to happen)
1242      - use Interior mask for OBCS in thsice_advection.F (similar to what is
1243        done in gad_advection & seaice_advection).
1244    o adjoint:
1245      bug fix spotted by Gael Forget:
1246      seaice_advection and thsice_advection still had
1247      legacy CPP options to avoid CS corner updates for adjoint
1248    o pkg/seaice:
1249      => Change some of the defaults (2011/05/29):
1250         - change SEAICEuseFluxForm default (from False to True)
1251         - change DIFF1 default (from 0.004 m/s to 0. m/s)
1252         And print warnings if DIFF1 is not set in data.seaice and centered
1253          avection scheme is used without any diffusion.
1254      also:
1255      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
1256      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
1257      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
1258        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
1259        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
1260      update results of test exp.:
1261         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
1262             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
1263             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
1264         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
1265         seaice_obcs: output (SEAICEuseFluxForm=T)
1266      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
1267          for standard fwd & AD lab_sea tests (to keep the same output).
1268    o pkg/seaice/seaice_growth.F:
1269      - use Ian Fenty's capping formulas for actual ice
1270      thickness thoughout EVOLUTION branch.
1271      - put treatment pathological case #2) in CPP brackets
1272      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
1273      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
1274    o pkg/seaice:
1275      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
1276      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
1277      also pass fac as a param, which can be 1. (to update the tendency
1278      field) or the time step (to update the field itself).
1279      - seaice_advdiff.F: for multidim, call seaice_diffusion with
1280      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
1281      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
1282      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
1283      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
1284    o pkg/seaice:
1285      diffusion with centered advection scheme (diffus.F & advect.F):
1286      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
1287        to just compute the laplacian of input-field.
1288      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
1289      - fix flux-form version in diffus.F to conserve tracer.
1290      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
1291       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
1292    
1293    checkpoint62y (2011/05/26)
1294    o pkg/seaice:
1295     - seaice_growth.F : in EVOLUTION branch, always include
1296       a_QSWbyATM_cover in qnet (as it should be).
1297     - verification/global_ocean.cs32x15 : update results accordingly
1298       (output.seaice.txt output_adm.seaice.txt).
1299    o pkg/seaice + obcs:
1300     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
1301       equivalent of assuming no tracer gradient outside the OB region.
1302       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
1303     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
1304       after changes above);
1305     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
1306       only at OB location (instead of over a band of OLx width).
1307    o pkg/seaice:
1308     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
1309       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
1310    o pkg/obcs:
1311      - split header file "OBCS.h" into 4 separated files:
1312        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
1313       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
1314         (contain no conditional statement which depends on OBCS options).
1315      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
1316        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
1317    o ctrl, cost, grdchk & autodiff pkgs:
1318      - make options file more standard (like other {PKG}_OPTIONS.h file but
1319        with AD_CONFIG.h); clean-up some of the included header files.
1320    o pkg/obcs:
1321      - do not mask tracer when applying OB (tracer == 0 could generate problems)
1322      - apply tracer OB values to tracer field only at OB location (instead of
1323        over a band of OLx width)
1324      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
1325      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
1326        obcs_apply_tloc.F & obcs_apply_sloc.F
1327    o obcs in model/src:
1328      - call OBCS_APPLY_W only if NonHydrostatic.
1329      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
1330      - reset dEtaHdt and wVel to zero outside OB interior region ;
1331      - leave tracer unchanged outside OB interior region: This has no effect
1332        on the solution but just to prevent unrealistic tracer value outside OB.
1333      - zero out velocity outside OB interior region: This has no effect on
1334        the solution but just to prevent unrealistic velocity outside OB.
1335    o obcs and non-lin free-surf:
1336       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
1337       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
1338       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
1339       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
1340       update results of test-exp. exp4(nlfs).
1341    o exp4 (nlfs) test-exp:
1342       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
1343       with NonLin-FreeSurf); update output.nlfs.txt
1344    o obcs and 2d/3d solver norm:
1345       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
1346       and outside OB interior region (will allow to place OB further inside the
1347       domain). Depending on the domain, can affects cg2d-Norm (previous
1348       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
1349       and cg3d-Norm (previous Norm was computed before canceling OB terms),
1350       e.g. in tutorial_plume_on_slope.
1351      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
1352    o pkg rbcs:
1353      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
1354      - add capability to apply relaxation to horizontal velocity uVel & vVel.
1355    o pkg/grdchk: add gradient check for control variable xx_shifwflx
1356    o pkg/shelfice/shelfice_init_fixed.F
1357      fix CPP-flag combinations
1358    o pkg/seaice: Merge iceage code of Pierre Rampal
1359      * update/change/correct ice age calculations
1360      * add age updates for pathological cases
1361      Probably needs more testing...
1362    
1363    checkpoint62x (2011/05/13)
1364    o pkg/mom_vecinv:
1365       high-order vorticity scheme: use interior masks (maskInW & S)
1366       to zero-out (outside OB) gradient of vorticity.
1367    o verification exp.:
1368       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
1369       hs94.128x64x5 and seaice_obcs ; update results.
1370    o pkg/obcs:
1371      fix bug in OBeta for YZ sections in obcs_exf_load.F
1372    o pkg/ctrl, pkg/shelfice, and optim:
1373      - add new control variable xx_shifwflx (fresh water flux underneath ice
1374        shelves). This is almost as tedious as obcs-ctrl, because the
1375        variables needs its own mask.
1376      - add a cost function term that penalizes the deviation of xx_shifwflx
1377        from the first guess (zero) in analogy to other control variables
1378    o pkg/shelfice:
1379      - start basic adjoint
1380    o pkg/ctrl:
1381      - remove extra 2D field "for good measure" when initializing in
1382        ctrl_set_globfld_[xy/xz/yz].F
1383      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
1384      - improve error messages in ctrl_set_unpack_*
1385    o OBC implementation in momentum:
1386       use interior masks (maskInC,W & S) in momentum S/R:
1387       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
1388       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
1389       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
1390       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
1391       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
1392        (and also with Leith/Smagorinsky harmonic-viscosity).
1393       Update output of experiment dome and exp4 (+nlfs).
1394    o exp4 test-exp:
1395      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
1396        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
1397        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
1398        time-varying OB at Western-side for wVel (NonHyd); update output.
1399      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
1400        and biharmonic-viscosity ; also use prescribed time varying OB.
1401    o pkg/obcs:
1402      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
1403    o model/src:
1404      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
1405      - initialise startTime & nIter0 with unlikely values: allows to set one
1406        from the other without ambiguity.
1407    o seaice_obcs test-exp.:
1408      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
1409    o pkg/obcs:
1410      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
1411        no longer needed with maskInC,W,S in pkg/generic_advdiff.
1412    o pkg/seaice:
1413      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
1414        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
1415      - fixed bug in the initialization of sea ice salinity variable HSALT
1416        in seaice_init_varia.F  (removed dependence on ICE2WATR)
1417    o fizhi-cs test exp.:
1418       switch reference output convention for these 2 non-standard test-exp,
1419        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
1420          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
1421       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
1422    o model/inc:
1423      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
1424        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
1425    o pkg/seaice:
1426      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
1427    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
1428      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
1429        and initial HSALT
1430    
1431    checkpoint62w (2011/04/26)
1432    o pkg/mom_fluxform:
1433      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
1434      - use parameter "sideDragFactor" in no-slip BC side-drag part.
1435      - update output of exp. global_ocean.90x40x15
1436    o pkg/mom_vecinv:
1437      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
1438    o update seaice exp.:
1439      use more consistent parameter values (remove "backward compatability only":
1440       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
1441      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
1442       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
1443    o update test-exp global_ocean.90x40x15:
1444      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
1445      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
1446      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
1447      o turn on zStar & viscA4 in standard set-up (dir input/)
1448        and update output files: output.txt & output.dwnslp.txt
1449    o new AD-test experiment: obcs_ctrl
1450      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
1451    o pkg/dic:
1452      fix two bugs in handling water vapour pressure in carbonate chemistry
1453      and air-sea fluxes. Found by Val Bennington and Galen McKinley
1454      (add DIC Option = WATERVAP_BUG to recover old results)
1455      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
1456    o adding allowInteriorFreezing option to check for water below freezing point
1457      at depth and bring the negative heat anomaly to the surface level
1458    o pkgs _fields_load:
1459      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
1460      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
1461        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
1462        rbcs to get interpolation weights and time reccord number.
1463      - fix multi-threading in aim_fields_load.F
1464      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
1465    o external_fields_load:
1466      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
1467       interpolation weights) to use in a periodic time-series ; do not divide by
1468       time-step to convert to integer:
1469       - this fixes case where externForcingPeriod is not multiple of time-step
1470          (Thanks to Christopher L. Wolfe)
1471       - this fixes case where externForcingPeriod is an odd multiple of time-step
1472         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
1473      store index of time-record which is currently loaded:
1474       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
1475       - needed for the adjoint but not yet used because of extensive recomputations;
1476         (to be fixed soon)
1477    
1478    checkpoint62v (2011/04/02)
1479    o verification/1D_ocean_ice_column added to test Ian Fenty's
1480      pkg/seaice_growth.F modifications for improving sea ice code differentiability
1481    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
1482      (new velocity statistics after changing maskInW & maskInS definition)
1483    o pkg/generic_advdiff with OBCS:
1484      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
1485      equivalent to assumption of no tracer gradient outside the OB region.
1486      This will affect the results if using obcs+biharmonic diffusion.
1487      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
1488    o pkg/obcs:
1489      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
1490      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
1491      in Interior region. No impact on solution but affects Velocity monitor stats.
1492    o pkg/ptracers (adjoint)
1493      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
1494      tape file for each tracer
1495    o model/inc/src and pkg/autodiff: add parameters that allow to turn
1496      of parts of the adjoint code at run time. For now, there are only
1497      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
1498      parameters are set in data.pkg.
1499      This is the lazy coward's version of doing this, but still useful for
1500      debugging. In order to do it right, everything needs to be moved to
1501      pkg/autodiff.
1502    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
1503      the end; this fixes the adjoint balancing code for open boundaries.
1504    o pkg/ctrl:
1505      - change behavior of xx_${varname}period to be analogous to exf-conventions:
1506        xx_${varname}period =   0.,  means time-independent control part
1507        xx_${varname}period = -12., means one-year-periodic monthly control part
1508      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
1509        clean up ctrl_init a little, remove unused variables
1510      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
1511      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
1512    
1513    checkpoint62u (2011/03/15)
1514    o model/src:
1515      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
1516        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
1517      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
1518        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
1519    o pkg/ctrl/obcs/ecco:
1520      - remove obsolete, unused, and partially broken code:
1521        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
1522        ALLOW_CTRL_OBCS_BALANCE
1523      - put a stop statement into ecco/cost_obcsvol.F, but also add
1524        cost_obcsvol to ecco_ad_diff.list
1525    o pkg/ecco: fix counting cost function contributions for obcs (code
1526      by Matt M.) and diffkr for diagnostics
1527    o pkg/ecco, pkg/ctrl, pkg/grdchk:
1528      add cost penalty terms for initial uvel, vvel, eta controls
1529      and I/O for prior error files
1530    o pkg/mdsio:
1531       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
1532       (new argument) to check for tiled file in mdsioLocalDir : this fix the
1533       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
1534    o pkg/ctrl:
1535     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
1536       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
1537       unused and superfluous variables
1538     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
1539    o pkg/ecco
1540     - enable adjoint of Stevens OB
1541    o pkg/ctrl/ecco/grdchk:
1542      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
1543        Fortunately, we do not have any tests for the numerous cpp-flagged
1544        option of "obcs as control parameters" so we will never know
1545        if this is an improvement (but at least now things compile).
1546      - remove an obsolete initialization from ecco_cost_init_barfiles.F
1547      - fix some problems within never used ifdefs to make the code compile
1548    o pkg/obcs:
1549     - Refine Interior mask definition to work with more complex OB (e.g.
1550       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
1551       read in Interior mask from file. Check if Interior mask is consistent
1552       with OB list of indices.
1553    o pkg/seaice
1554     - beginning code for a seaice tracer package,
1555       but currently only used for seaice age: SEAICE_AGE
1556       SEAICE_num = 4
1557       iTracer = 1: area-weighted ice age
1558               = 2: volume-weighted ice age
1559               = 3, 4: template for one-year vs. multi-year ice
1560       data.seaice has new namelist SEAICE_PARM03 for arrays related to
1561       SEAICE_num
1562    
1563    checkpoint62t (2011/03/05)
1564    o pkg/obcs:
1565     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
1566       then normal component. This ensures that the normal component is set
1567       correctly even when it conficts with tangential setting from an other OB.
1568       Affects results of test-experiment seaice_obcs: update the output.txt
1569    o pkg/obcs:
1570     - add code to monitor statistics of dynamical fields at OB.
1571     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
1572       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
1573       - change default: balance the Net inflow through all OB (instead of balancing
1574         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
1575     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
1576       to match Nortern OB inflow (OBCS_balanceFacN=0).
1577    o pkg/seaice:
1578     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
1579    o pkg/seaice (seaice_growth v 1.113):
1580     - reverting seaice_growth to v 1.111 in order to have code with exact bit
1581       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
1582       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
1583       runtime flag SEAICEareaFormula is kept but is inactive
1584    o model/src:
1585     - add new param to scale curvilinear grid distance and area when using
1586       a different sphere radius from the grid-files.
1587     - test/check multi-threads EXCH applied to local variable (cg2d_x)
1588    o adjoint:
1589     - enable adjoint of Stevens OB
1590     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
1591       (a bit delicate because of potentially modified adj. common block structure;
1592       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
1593    
1594    checkpoint62s (2011/02/15)
1595    o pkg/seaice (seaice_growth v 1.112):
1596     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
1597       computing the ice cover tendency from effective thickness tendencies. Include
1598       Ian Fenty's formula.
1599     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
1600       SEAICEareaFormula.
1601     - simplify notations for the various d_HEFF/d_AREA terms.
1602    o pkg/gmredi:
1603     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
1604       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
1605       add a verification test-run (front_relax.bvp) to test GM_useBVP.
1606    o pkg/seaice (seaice_growth v 1.111):
1607     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
1608     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
1609       also melt ice.
1610    o pkg/seaice:
1611     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
1612     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
1613    o pkg/cheapaml:
1614     - from Nico Wienders: New version of this package.
1615    o pkg/flt:
1616     - add CPP options to prevent floats to re-enter the opposite side of
1617       a periodic domain (default: keep periodicity)
1618    o pkg/gmredi:
1619     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
1620       (needed for multi-dim advection).
1621     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
1622    o model/src:
1623     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
1624    o tutorial_tracer_adjsens
1625     - extend to NLFS and replace maskC by hFacC
1626       (change reference output accordingly)
1627    
1628    checkpoint62r (2011/01/24)
1629    o testreport:
1630     - add option -deloutp (-do) to remove output file after successful run
1631     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
1632       extract exact list of procs from this file ; adjust COMMAND by
1633       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
1634    o pkg/ecco: replace old ineffective way of penalizing deviations from
1635      first guess (of obcs) with code by Matt Mazloff
1636    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
1637      exf/cal
1638      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
1639        and handle case of obcs?period == 0
1640        Not affected by these changes: There is still an inconsistency in
1641        the computation of start/endrec for the obcs variables for ALLOW_CAL
1642        defined (see comment by Menemenlis, 7-Mar-2003)
1643      - make S/R ctrl_get_gen_rec return something meaningful even if
1644        ALLOW_CAL is not defined
1645      - ctrl_getobcs?: simplify code so that it does not need to use
1646                       S/R exf_swapfields
1647    o testreport:
1648       allow to test MPI with different number of processors for each experiment:
1649       create file "SIZE.h.mpi" in each build dir.
1650       Note: update of "-command" argument not yet implemented.
1651    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
1652      alleviate the need for additional 3D tapes when using
1653      the non-inear free surface in the adjoint. This is done
1654      by adding an 'update' of hfacc etc. to their current
1655      value at the beginning of forward_step.F.
1656    o pkg/seaice
1657      seaice_lsr: move stress-divergence computations out of outer pseudo-
1658      timestepping loop
1659    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
1660      up, so that the calls of the ctrl_* subroutines are really at the end
1661      of the routine.
1662    o pkg/gmredi:
1663      allow to specify a 2-D horizontal map and a 1-D vertical profil
1664      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
1665    o pkg/seaice:
1666      move lsr iterations from seaice_dynsolver to seaice_lsr.
1667    o pkg/seaice:
1668      reduce memory footprint of seaice mutldim advection tapes,
1669      by using a 2D tape independent of the generic_advdiff ones,
1670      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
1671    
1672    checkpoint62q (2010/12/29)
1673    o model/src:
1674      - check horizontal grid-spacing for unset or zero/negative values.
1675      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
1676    o pkg/flt:
1677      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
1678      - precision of input and output files set according to readBinaryPrec
1679        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
1680      - initial float position from tiled file was not converted to index space
1681        (looks like a bug): fixed to make it similar to initial pos. global file.
1682    o global_ocean.cs32x15:
1683       change SIZE.h of AD set-up to get same tiling as with MPI.
1684       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
1685    o model/src:
1686       add flag to control printing of domain fields (bathymetry, hFac ...) in
1687       ini_mask_etc (call to plot_fieds_xy*).
1688    o pkg/thsice:
1689       if useEXF, some forcing fields are not valid in overlap: fixed by computing
1690       over the interior only + apply EXCH at the end (like with SEAICE advection).
1691    o pkg/mdsio:
1692      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
1693        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
1694      - change barrier call for safe multi-threads access to 3-D shared buffer.
1695      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
1696      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
1697        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
1698    o pkg/flt:
1699      - add fourth-order Runge-Kutta integration
1700      - add basic exch2 support (only 1 facet supported so far!)
1701    o pkg/mdsio+rw:
1702      new S/R to read local (or tile independent) vector (read counterpart of
1703       mds_writevec_loc, and front-end write_glvec_rl/rs).
1704    o global_ocean.cs32x15: additional input_ad.seaice experiment
1705        that uses pkg/seaice rather than pkg/thsice.
1706        (using multidim advection for seaice)
1707    o towards more F95 syntax for array specification in namelist:
1708      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
1709        of all verification experiments.
1710           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
1711          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
1712      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
1713    o global_ocean.cs32x15: additional input.seaice experiment
1714        that uses pkg/seaice rather than pkg/thsice.
1715    
1716    checkpoint62p (2010/12/17)
1717    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
1718        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
1719    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
1720        allow for use of multim. advection in seaice adjoint.
1721    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
1722      - first attempt to close budgets by taking into account the freshwater
1723        flux implied by the sublimation of snow and ice. So far only the
1724        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
1725        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
1726    o eesupp/src:
1727      new S/R with new option (NML_EXTENDED_F77) to change array specification
1728      from F95 standard to commonly accepted extended F77 form.
1729      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
1730      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
1731      for less tolerant f77 compiler (e.g., pgf77, g77).
1732    o globalFiles:
1733      commented out in parameter file "data" since it's not safe with MPI
1734      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
1735      in this case); no longer commented out in restart test (tst_2+2).
1736    o add adTapeDir to specify a special directory where adjoint tapes are
1737      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
1738      and cannot be used together with mdsioLocalDir.
1739    o nesting pkgs:
1740      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
1741      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
1742      - add parameter files + utils dir + output from short run on beagle.
1743    o pkg/seaice:
1744        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
1745    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
1746      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
1747    
1748    checkpoint62o (2010/11/25)
1749    o pkg/exf:
1750      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
1751    o pkg/seaice:
1752      - seaice_ocean_stress: split a loop for better vectorization of the
1753        adjoint code
1754      - seaice_growth.F: fix bug in conservation of freshwater connected to
1755        capping of heff, put contribution into d_HEFFbyNEG
1756      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
1757        by something more sensible (parameters that are what their name implies)
1758      - change some defaults, so that by default exf-parameters are used for
1759        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1760        to reproduce the old results, many data.seaice now contain funny values
1761        for cpAir and latent heat of sublimation
1762    o packages_readparms.F: move exf_readparms up in line so that
1763        exf-parameters are visible for other packages (e.g. seaice)
1764    o debugMode & debugLevel=2:
1765      - differentiate between debugMode & debugLevel=2:
1766        debugMode: controls printing of debug messages (sequence of S/R calls).
1767        debugLevel: controls printing of algorithm intermediate results and stats.
1768      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1769        => allows to print debug-stats without all sequence of call messages.
1770      - switch control of debug print from debugLevel to debugMode in many S/R.
1771    o pkg/obcs (obcs-sponge):
1772        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1773        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1774    o pkg/generic_advdiff:
1775      - record overlap minimum size for each advection scheme;
1776      - refine criteria on overlap minimum size;
1777      - check and stop (in gad_check) if overlap size is too small.
1778    o pkg/obcs:
1779      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1780        once, in ptracers_implicit.F)
1781      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1782        apply OB values when tile has OB)
1783    o model/src, coriolis setting:
1784      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1785        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1786        files (selectCoriMap=3) with any grid.
1787      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1788    o pkg/seaice/seaice_growth.F:
1789        a few cosmetic changes that reduce the number of lines of code
1790    o pkg/obcs: add boundary conditions following Stevens (1990)
1791      - the code follows old MOM/NAOSIM code
1792      - so far it is only implemented for the eastern and western boundaries
1793        and NOT for pTracers
1794    o pkg/rbcs:
1795      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1796        beginning of the first rbcs forcing period.
1797      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1798        offline package, i.e., one file per time, labeled by iteration number;
1799        deltaTrbcs sets the timestep with which the data was generated;
1800        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1801      - rbcsForcingCycle=0 makes forcing non-cyclic.
1802      - make arithmetic safe for negative times and odd forcing periods.
1803    
1804    checkpoint62n (2010/11/09)
1805    o pkg/seaice:
1806        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1807    o pkg/obcs:
1808       New S/R to copy tracer value from the OB location to narrow band region
1809        (width = same as overlap) beyond the OB: preserve OB value (needed for
1810        high-order scheme) which were overwritten by EXCH call if in overlap
1811        region. Applied to theta, salt, ptracer and advected seaice variables.
1812       With seaice: use maskInC in similar way as in gad_advection.F,
1813        in seaice_advection.F and advect.F.
1814       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1815        4th order Adv.Scheme. for pasive salt and ptracer.
1816    o tools/genmake2:
1817      - when looking for an optfile (not specified), only search for Fortran compiler
1818        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1819      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1820        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1821      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1822        an optfile, but otherwise default was just "cpp".
1823      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1824      - when "CC" is not set in the optfile, look for possible C compiler
1825        (instead of just setting CC=cc)
1826      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1827        => add a ".F" to ".o" rule for source files with no "#include" (such as
1828           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1829      - move gfortran before g77 in list of possible Fortran compiler (consistent
1830        with reference compiler switch from g77 to gfortran)
1831    o pkg/seaice:
1832      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1833        seaice_check that stops the model, when the CPP flag is used.
1834      o seaice_growth.F: make capping of ice volume conserving by returning the
1835        capped ice as freshwater to EmPmR. This does not change the verification
1836        experiments but will change runs where the capping is acutally active
1837    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1838      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1839         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1840         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1841    o tools/genmake2:
1842      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1843      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1844      - clean previous genmake log files before anything else.
1845      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1846        files only with "CLEAN" target (instead of "Clean");
1847    o pkg/generic_advdiff:
1848      Change OBCS in multiDim advection (gad_advection.F):
1849       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1850       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1851       which were applying future time-step OB values.
1852      This way, all explicit calculations use current-time-step OB values
1853       (simpler and more consistent).
1854      Affects results when set-up uses time-varying OBC and multi-dim advection;
1855       update output of experiment seaice_obcs.
1856    o pkg/seaice:
1857      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1858       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1859         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1860      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1861       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1862       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1863    o pkg aim (2010/10/26):
1864      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1865        formulation with obliquity, eccentricity, ... as run-time parameters,
1866      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1867        upward shortwave radition at the surface (all-sky and clear-sky).
1868    o pkg/obcs:
1869      - writing sections with globalFiles=T does not work: switch to tiled-files
1870        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1871      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1872      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1873    
1874    checkpoint62m (2010/10/21)
1875    o pkg/seaice: vectorize seaice_solve4temp.F
1876      - move iterations loops outside of i/j-loops
1877      - requires 2D arrays for TB and effConduct
1878      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1879        modified in this routine
1880      - a little bit of clean up, adjusting indentation, etc.
1881      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1882        performance and '**TWO' by '**2' (because TWO is a float),
1883        replaced ONE, ZERO
1884    o eesupp/src:
1885       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
1886    o pkg/seaice/seaice_growth.F
1887      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
1888      merging process. The merged routine has two branches, and one activates the 'evolution'
1889      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
1890      In summary, here is what the '10/10 revision' did consist of
1891        part 1: seaice_growth.F revisions 1.71 to 1.75
1892          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
1893            The emphasis here was on improving readability (e.g. by trying to use meaningful
1894            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1895        part 1.5:
1896          - revising the lab_sea experiment to make it a more useful (i.e. stable
1897            and representative of an actual model run). This was done by generating a
1898            (winter) pickup to start from, switching back the main experiment dynamic
1899            solver from evp to lsr, having one of the experiments use the free drift solution.
1900        part 2: seaice_growth.F revisions 1.76 to 1.85
1901          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1902          - Sorting out the various fields units and sign (set early on and reset at the end)
1903            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1904            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1905          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1906            and simplifying logical expressions to further improve readibility.
1907        part 3: seaice_growth.F revisions 1.86 to 1.89
1908          - Re-organize the blocks of code more logically.
1909          - Merging the '_if.F' pieces that add something new.
1910    o pkg/thsice:
1911      - vectorize thsice_solve4temp and thsice_get_exf.
1912        Problem: thsice_solve4temp has an unvectorizable statement that
1913        might also be problematic for TAF
1914      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1915        does not change the verifcation experiment, but will change all
1916        experiments that have this flag undefined (not tested in verification);
1917        a little reorganization to save a few 2D fields and recomputations
1918      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1919      - 2nd step:  fix some store dirs
1920        o seems to work somewhat, i.e. using ifort but not g77
1921        o likely cause are incomplete init. or recomputation
1922        o start verification/global_ocean.cs32x15/input_ad.thsice
1923    o pkg/obcs: add support for exch2
1924      - the position of the boundary and prescribed values are specified using
1925        a global domain with exch2 facets stacked
1926        - in x for N,S boundaries (like W2_mapIO=-1)
1927        - in y for E,W boundaries (so E,W boundaries do not overlap)
1928    o pkg/mdsio: add support for writing global sections with exch2
1929        file layout is as for obcs described above:
1930        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1931        - for y-z sections, facets are stacked in y
1932    o pkg/thsice:
1933       - change a few routines for better vectorization: thsice_albedo.F,
1934         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1935         not affected, but in particular the latter routine has changed
1936         dramatically (not necessarily easier to read now).
1937       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1938       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1939    o verification/lab_sea:
1940      - overhaul of the forward model experiments. The main motivation
1941        for this revision is that lab_sea has proven quite fragile (when
1942        changing the sea-ice code, and switching platforms) to a point
1943        when failures were very hard to attribute to specific code problems.
1944      - the suspected reason for this fragility is noise amplification by evp so,
1945        to start with, we decided to replace evp with lsr in the main experiment.
1946      - the input.lsr experiment thus became obsolete and was removed.
1947      - it was replaced with the input.fd experiment that uses an
1948        analytical "free drift" solution as the ice velocity field.
1949      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1950        will hopefully allow us to discriminate problems due to dynamic solvers
1951        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1952        us to test additional options, along with the salt plume package.
1953      - Finally a pickup was generated (at the end of a one year run) to
1954        make the tests more representative of an actual model run. Previously
1955        the tests starting point was a 1m thickness of ice everywhere.
1956    o pkg/seaice:
1957      - introducing S\R seaice_freedrift.F that compute the
1958        analytical solution to an approximate ice momentum
1959        equation (i.e. the simple stress/coriolis balance).
1960      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1961        of the free drift velocity field, and enable its use.
1962        To actually use the free drift solution as the model ice
1963        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1964    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1965    
1966    checkpoint62l (2010/10/04)
1967    o pkg/seaice:
1968      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1969      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1970       version (with USE_ORIGINAL_SBI undef);
1971    o add hooks for new packages OASIS, the package will follow
1972      (hooks exclude the seaice pkg for now)
1973    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1974      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1975      rather than mdsio_readvector.F/mdsio_writevector.F, within
1976      adread_adwrite.F to read/write adjoint-related tapes to disk.
1977    o eesupp and pkg/mdsio: ALLOW_WHIO
1978      Option to write/read 2D fields to files including tiles halos.
1979      The main purpose is for adjoint related "tape I/O".
1980      The secondary purpose is for debugging phases.
1981      A word on those rather specifically intended purposes.
1982      The code was meant to be stripped down to the bare minimum.
1983      Typically, there is a unique and basic mapping to the global
1984      buffer (tile by tile, then proc by proc, then level by level), and
1985      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1986      meant to generate user friendly outputs of various shapes and forms.
1987      Rather it is intended, for the knowledgeabale developers,
1988      to be largely independent of the many mdsio options, to allow
1989      outputs of tiles+halos in debugging phases and in adjoint runs,
1990      and to allow some flexibility in tuning (adoint) I/O depending on each
1991      file system behavior. With regard to tuning, most of the potential knobs
1992      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
1993      to specify directories, to specify the typical size of I/O calls, etc.)
1994      are not yet included, and will be added if they prove useful.
1995    o pkg/seaice:
1996       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
1997    o pkg/seaice:
1998       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
1999       code (seaice_budget_ice_if.F) which enable to recover old standard
2000       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
2001       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
2002    o model/src (rStar):
2003       use simple average (not area weighted) of rStarFac at U,V point when using
2004       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
2005       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
2006    
2007    checkpoint62k (2010/09/17)
2008    o adjoint
2009       * changed verification/global_ocean.cs32x15 ; adjoint now tests
2010         Adams-Bashforth 3 + NLFS + RSTAR
2011       * some more modifs required for ECCO-GODAE v4
2012    o pkg/seaice
2013       add SEAICE_AGE_VOL option to use volume instead of area for
2014       integrating SEAICE_AGE
2015    o model/src:
2016       first check-in of sigma & hybrid-sigma coordinate code ; also includes
2017       non-linear free-surface parts ; but pressure-gradient not yet coded.
2018    o pkg/ptracers:
2019       option for ptracer to convert Salt Relax into additional EmP.
2020        tested in exp. global_ocean.90x40x15.dwnslp (update output)
2021    
2022    checkpoint62j (2010/08/25)
2023    o pkg/ggl90:
2024       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
2025    o pkg/dic: car_flux.F, phos_flux.F
2026      - reduce number of exp-calls in order to improve performance
2027      - clean up a little (replace fields by their macros, etc., fix
2028        typo in CPP-flag)
2029    o pkg/ggl90: minor changes
2030      - GGL90diffKrS was removed --> always use GGL90diffKr
2031      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
2032      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
2033        (commented out for now)
2034      - change in max/min operations to ensure that smoothing is ok
2035      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
2036      - always use diffKrNrT as background profile (i.e. never use diffKr field)
2037    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
2038    o pkg/dic:
2039      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
2040        vectorization
2041      - small bug fix in insol for the unlikely case of a cartesian grid
2042      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
2043        + now vectorize, which also removes adjoint recomputations;
2044        + replace integer maksp1 by _RL maskp1
2045        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
2046    
2047    checkpoint62i (2010/07/21)
2048    o pkg/flt:
2049      - with OBCS: stop floats which enter the OB region
2050    o model/src:
2051      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
2052        for implicit vertical advection.
2053    o pkg/seaice:
2054     - account for melting in seaice age evolution.
2055     - remove double counting of seaice ridging effect on seaice age.
2056    
2057    checkpoint62h (2010/06/18)
2058    o pkg/exch2:
2059     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
2060    o tools/genmake2
2061      - remove "-pdefault" option: redundant with the use of "packages.conf";
2062      - remove file pkg/pkg_default : set the default as a pkg group
2063        ("default_pkg_list") defined in pkg/pkg_groups;
2064      - fix for case pkg/pkg_depend is missing (was hanging before);
2065      - add option "-pgroups" to specify a different pkg_groups than the default.
2066    o verification/adjustment.cs-32x32x1:
2067       add a "minimal" set-up test (code_min & input_min) which only compiles
2068       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
2069    o tools/genmake2
2070      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
2071      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
2072    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
2073      files are nearly the same anyway.
2074      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
2075       - redefinition of tau(i,i) (by a factor of ustar)
2076       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
2077       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
2078       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
2079       - replace
2080         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
2081         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
2082         by
2083         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
2084         (changes results)
2085       -> exf_bulkformulae v1.22,
2086          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
2087          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
2088                    output.txt 1.63
2089           offline_exf_seaice: output.seaicetd.txt 1.7
2090           seaice_obcs: output.txt 1.10)
2091      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
2092       -> exf_bulkformulae v1.23,
2093          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
2094          and global_ocean.cs32x15.icedyn (only 11 matching digits)
2095      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
2096    o adjoint of exch-1:
2097     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
2098       (note: was already like this when using EXCH-2) and remove flow dir
2099       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
2100     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
2101     - update pkg/exch2 diff list.
2102    
2103    checkpoint62g (2010/05/19)
2104    o eesupp/src (exch-1):
2105     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
2106       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
2107       (renamed to exch1_*rx_cube.F).
2108     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
2109       to call new exch1 S/R ; update Makefile and .cvsignore.
2110     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
2111       exch2_xy_rx later)
2112      Note: after updating your code, need to run "make clean" in eesupp/src
2113    o test experiment bottom_ctrl_5x5:
2114       new output_adm.txt with fewer grdchk & less monitor output.
2115    o model/src:
2116      remove the call to ini_cori in initialise_varia.F (just keep the usual one
2117       in initialise_fixed.F). More consistent with coriolis & horizontal grid
2118       beeing treated in the same way (ini_grid is not called a 2nd time).
2119    o pkg/exf:
2120      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
2121      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
2122      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
2123      - cosmetic changes to exf_bulkformulae.F to make it look more like
2124        exf_bulk_largeyeager04.F
2125    o eesupp/src (exch-1):
2126      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
2127      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
2128        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
2129        (even without using MPI).
2130      - Message mode: move RecvAck setting (indicator of buffer being ready)
2131        from send_put to recv_get S/R (was useless before, but not sure if
2132        it's much more useful now);
2133      - Switch the order of sync: MPI-proc 1rst and then threads;
2134      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
2135      - fix AD code for communication mode ='get' (but not used).
2136    o model/src:
2137      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
2138      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
2139    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
2140    o pkg/ctrl: require a specific set of control variables and exf-flags for
2141      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
2142    o model/src:
2143     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
2144       1rst forward sweep, to avoid over-writing output files during recomputations
2145       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
2146     b) 2nd version:
2147      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
2148      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
2149         writePickupAtEnd) + seaice & ptracers output;
2150      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
2151    o model/src:
2152      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
2153    o pkg/exch2:
2154      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
2155      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
2156    o pkg/autodiff & exch2:
2157      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
2158      (for now, only if ALLOW_EXCH2 is defined).
2159    o pkg/autodiff:
2160      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
2161        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
2162       + clean-up comments (_RS is not always real*4)
2163      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
2164      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
2165        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
2166    o testreport (AD-tests):
2167      no longer link files from dir "../input" (1rst link files from
2168      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
2169    
2170    checkpoint62f (2010/04/29)
2171    o model/src/the_main_loop.F:
2172      adjust store directives for seaice evp and multicategory according to
2173      pkg/ecco/the_main_loop.F
2174    o adjoint:
2175      global_sum_ad was incomplete (noted many times by many people ;)
2176      nice description by Jean U. as follows:
2177      * allreduce(var) in global_sum.F can be interpreted as
2178        reduce(sum) followed by broadcast of sum.
2179      * The adjoint of that is
2180        sum(adjoint) followed by broadcast(summed adjoint value)
2181        or in other words, allreduce(sum, adjoint vars)
2182      We were missing the sum(adjoint)!
2183      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
2184      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
2185      The fix should produce 16-digit accuracy between
2186      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
2187      multi-CPU single-tile (e.g. nSx=1, nPx-2)
2188      We'll probably change this yet again shortly
2189    o eesupp/src:
2190      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
2191    o pkg/icefront
2192      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
2193        specification of addmass array based on a 2D field, which is added
2194        at bottommost wet level at each horizontal location.
2195    o model/src:
2196     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
2197     layout; (not always compatible with delX,delY setting; commented out for now).
2198    o pkg/exch2:
2199     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
2200     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
2201    
2202    checkpoint62e (2010/04/15)
2203    o pkg/obcs:
2204      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
2205    o pkg/dic:
2206      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
2207        (note: not presently tested in any forward verification exp.)
2208       update tutorial_global_oce_biogeo AD output file.
2209    o pkg/exf:
2210      - account for the variation of albedo as a function of zenith angle
2211        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
2212    o build_options:
2213     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
2214    o pkg/dic:
2215      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
2216      - use binary pickup file for restart;
2217      - initialise atmos-CO2 box from dic_pCO2 parameter;
2218      - fix multi-threaded.
2219    o pkg/rbcs:
2220     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
2221       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
2222     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
2223       and update output.txt
2224    o pkg/kpp:
2225     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
2226     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
2227       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
2228       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
2229     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
2230       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
2231    o pkg/offline:
2232      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
2233      (bug was added in version 1.10 on 2007-08-23).
2234    o pkg/offline:
2235      - no need to specify periodicExternalForcing, etc ... to use offline pack
2236      - offline input files no longer just single prec --> parameter offlineLoadPrec
2237    o verification/lab_sea:
2238      change AD test to multi-tile setup and update all 4 AD output.
2239      NOTE: while cost function values remain very similar,
2240      gradients are very different, although gradient checks are self-consistent
2241      Should try to get to the bottom of this (cost function summation order?)
2242    o pkg/dic:
2243      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
2244      a weakness of TAF that drops part of double precision in log10 derivative.
2245      <= changes removed since problem has been fixed in current TAF version 1.9.71
2246      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
2247    o pkg/ecco:
2248      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
2249      update all 4 lab_sea AD output.
2250    
2251    checkpoint62d (2010/03/22)
2252    o build_options:
2253      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
2254    o remove unbalanced quote (single or double) in commented line of source code
2255      (may cause some warning with some preprocessor/makedepend versions).
2256    o pkg/seaice:
2257      fix seaice_model.F for adjoint (gael) and update AD results of experiments
2258       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
2259    o testreport:
2260      add option '-runonly' (short: '-ro') to just do the run part (without make).
2261    o eesupp: remove JAM communication code (obsolete).
2262    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
2263      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
2264      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
2265      (update also the output).
2266    
2267    checkpoint62c (2010/03/02)
2268    o tools/build_options :
2269       move (some) old optfiles from build_options/ to build_options/unsupported/
2270    o model/src and pkg/exf
2271       surface relaxation -- separating data and data.exf options
2272       The point is to ensure that we specify the surface relaxation
2273       either in data or in data.exf (but not half and half) and to
2274       avoid an accidental relaxation to 0 (which happened if a time
2275       scale was specified but the file name was left empty)
2276    o model/src model/inc and pkg/mom_common
2277       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
2278       => addition to the viscosity field as computed by others schemes
2279    o tools/build_options:
2280      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
2281        but keep the former optfile for few weeks for smooth transition
2282    o pkg/ecco
2283      - allow user defined cost function contributions
2284         CPP: ALLOW_USERCOST_CONTRIBUTION
2285         USAGE: compute contributions in cost_usercost_all.F
2286      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
2287          the two options are complementary.
2288    o pkg/smooth
2289      - migration from contrib to the main repository
2290    
2291    checkpoint62b (2010/01/26)
2292    o pkg/monitor:
2293      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
2294        (in case someone forgot to update customized pieces of code)
2295    o nonHydrostatic:
2296      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
2297      - add a simple 2-D experiment (short_surf_wave) to test it.
2298    o pkg/icefront:
2299       adding the shell of, and the hooks to, a new package that
2300       will model melting and freezing of vertical glacier ice fronts
2301    o momentum:
2302      add diagnostics of momentum tendency from Hydrostatic pressure gradient
2303       (without surf.pressure term: would need a 2nd filling since implicit term).
2304    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
2305      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
2306      cannot deal with the former
2307    o cleaning:
2308      - remove all (except OpenAD) old TLM output from results_ad dirs.
2309      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
2310      - comment out maskH definition (replaced by maskInC)
2311    o pkg/monitor:
2312      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
2313        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.
2314    
2315    checkpoint62a (2010/01/15)
2316    o model/src:
2317      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
2318    o pkg/diagnostics:
2319      - add optional level number diagnostics (i.e., level number to be define
2320        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
2321      - strictly check for valid parser-code(10) ;
2322      - check if adding diag to the list from the right place.
2323    o pkg/longstep:
2324      - change parameters and fix tracer conservation with rstar/nonlinear free surface
2325    o diagnostics:
2326     - in all pkgs, replace remaining calls to old S/R DIAGNOSTICS_ADD2LIST with newer
2327       S/R DIAGNOSTICS_ADDTOLIST ; fix seaice VICE diagnostics.
2328    o pkg/diagnostics:
2329     - Add option for writing vertical integral (sum of selected levels) of an output
2330        field instead of writing output field levels. Activate this option on a per
2331        output-file basis, by setting the 2nd character of fileflag to 'I'.
2332     - Add field-specific information relative to level integral in 3rd postion
2333        of parser diagnostics code (gdiag): " "=cumulate levels, "R"=integrate
2334        vertically (x level-thickness x hFac), "r"=same but without hFac.
2335    o do_the_model_io:
2336      - pass end-of-model-run flag as argument, from forward_step to diagnostics_write:
2337        in case useSIGREG, will write (averaged) diagnostics (if dumpAtLast) before
2338        writing pickups and stopping.
2339    o pkg/diagnostics (for now, only with mdsio):
2340      - write time information to meta file (and modify accordingly rdmds.m) :
2341        time-averaged diagnostics output: write starting and ending time of the
2342        time-averaging interval ; snap-shot diagnostics output remains unchanged;
2343    o pkg/timeave:
2344      - S/R TIMEAVE_NORMALIZ: change size of cumulated-time array (was previously
2345        always Nr), now assumed to be equal to number of levels of averaged field;
2346        only used for DIC_COST monthly mean arrays: this fixes dic_aver_final.F
2347    o pkg/sbo:
2348      - fix ocean bottom pressure global-average & 2-D time-ave output (was
2349        neither initialised nor filled).
2350      - add starting iteration in suffix of global-average output file
2351        (to avoid over-writing the file after a restart)
2352      - use standard MDSIO pkg S/R instead of SBO_WRITEVECTOR (fix byte-swap Pb).
2353    o time-average:
2354      - use simple cumulative-time array (no k index) in all pkgs: {PKG}_timeAve(bi,bj)
2355        (pkgs: aim_v23, bulk_force, dic, gmredi, kpp, land, ocn_compon_interf,
2356         ggl90, my82, opps, pp81, ptracers, sbo, seaice, shelfice, thsice)
2357        this fix DIC_COST cumulative-time array (previously: bi,bj,k)
2358      - fix 1rst call (nIter0) snap-shot output and accumulation (pkg/shelfice)
2359      - fix missing accumulation for pkg/opps.
2360      - cumulate fields only if doing time-ave output ({PKG}_taveFreq > 0)
2361         (pkgs: ptracers, kpp, ocn_compon_interf, ggl90, my82, pp81);
2362      - fix initialisation of time-ave vars and do only full time-step increment
2363        (i.e.: no first & last "half time-step") (pkgs: ggl90, my82, opps, pp81);
2364    o pkg/layers:
2365      - use standard RW pkg S/R to write the output
2366        and remove local write_fld version (which had a problem).
2367      - use simple cumulative-time array (no level index) to fix time-ave S/R calls.
2368      - fix LAYERS_CALC argument list.
2369    o pkg/timeave:
2370      - store cumulative-time in a simple tiled array (drop the level index)
2371      - add new S/R (TIMEAVE_NORMALIZE) which uses simple cumulative-time array.
2372    o pkg/ocn,aim_compon_interf
2373      - changes for multi-threaded coupled run. (tested with ifort-11 on danton)
2374    
2375    checkpoint62  (2009/12/23)
2376    o switch on useOBCSbalance in tutorial_plume_on_slope exp. and update output.
2377        (was not previously tested in any other exp.)
2378    o pkg/monitor:
2379      - clean-up _RL/_RS version: add specific S/R for statistics with mask & volume:
2380        mon_writestats_rl/s,F mon_calc_stats_rl/s.F ; will keep the old one
2381        (mon_printstats_rl/s,F mon_stats_rl/s.F) just for bare statistics.
2382      - use hFac & 2-D mask (instead of 3-D mask + hFac in previous mon_stats_rl.F).
2383      - change del2 calculation.
2384      - use interior masks (instead of maskH, <- to be remove).
2385      - shorter monitor suffix for forcing stats ("forcing" instead of "extforcing").
2386    o mask & obcs:
2387      - define 2-D "interior" masks (i.e., zero beyond OB) at 3 locations (C, W & S).
2388      - move global area computation from ini_masks_etc.F to ini_linear_phisurf.F
2389        (called after packages_init_fixed)
2390    o pkg/obcs:
2391      - move bi,bj loops into obcs_calc, so obcs_prescribe_read is called only once.
2392        Fixes bug in obcs+exf with nSx*nSy.GT.1
2393      - fix multi-tile handling in obcs balance code
2394    o nonHydrostatic:
2395      - Implement AB-3 for non-hydrostatic vertical momentum ;
2396        (change ordering of var. stored in pickup file when using NH)
2397      - move NH code from solve_for_pressure.F to 2 new S/R: PRE_CG3D & POST_CG3D.
2398      - add 2-D field to store Hydrostatic Surface Pressure adjusment from cg3d_x
2399        (in prep. for new NH free surface form).
2400    o pkg/obcs:
2401      add files & OB-variables for wVel (Non-Hydrostatic) with useOBCSprescribe
2402    o model/src:
2403      fix 2-D solver initialisation for deep-atmosphere (p-coord) with topography
2404    
2405    checkpoint61z (2009/12/01)
2406    o nonHydrostatic:
2407      Fix missing vertical flux of vert. momentum near surface (k=1). This fixes
2408        a spurious source of energy in simple baroclinic adjusment test case.
2409      Update all non-hydrostatic exp output.
2410    o model/src (3-d solver):
2411      Change again 3-D solver free-surface RHS term when exactConserv=T:
2412        simpler, consistent with exactConserv, and works with implicDiv2Dflow < 1
2413        (which was not the case with previous formulation).
2414      To recover previous version, just reset "oldFreeSurfTerm" to previous value.
2415      Affects results of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW.
2416    o nonHydrostatic:
2417      - compatible with implicDiv2Dflow < 1 ; + implement implicit factor
2418        for Non-Hydrostatic pressure gradient (similar to implicSurfPress).
2419      - change 3-D solver to work with r* (for now, only with linear free-surf.)
2420      - add few debug diagnostics (cg3d_x, residual)
2421    o model/src:
2422      fix missing EmPmR in 3-D solver RHS (was in cg2d_b but missing in cg3d_b).
2423        update output of exp. global_ocean.cs32x15.viscA4
2424    o update output of exp. global_ocean.cs32x15.icedyn after removing
2425      #define SEAICE_OLD_AND_BAD_DISCRETIZATION from SEAICE_OPTIONS.h
2426    o add entry points for Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
2427    o mnc: add horizontal grid coordinates (XC,YC) and (XG,YG) to netcdf output
2428      for complex grids, for now only to "state", "adstate", "adexf", "adseaice"
2429    o model: add Christopher Wolfe's implemetation of the single reduction cg2d
2430      (d'Azevedo, Eijkhout, and Romine, 1999) with CPP-flag ALLOW_SRCG and
2431      runtime flag useSRCGSolver. Modify verification experiment global_with_exf
2432      to test this code
2433    o pkg/cd_code:
2434      Change defaut D-grid time-stepping to get the same for D-grid momentum as for
2435       C-grid momentum. D-grid velocity used to be stepped forward in time with
2436       Adams-Bashforth only on surface pressure term. Tests show that using AB on
2437       D-grid coriolis term improves stability (as expected from CD-scheme paper).
2438      To reproduce old results, add 2 options (in CD_CODE_OPTIONS.h).
2439      Update results of exp: global_with_exf (x2), ideal_2D_oce, isomip (x2),
2440       lab_sea (3 Fwd +3 AD), natl_box (x2), tutorial_global_oce_biogeo (Fwd+AD),
2441       tutorial_global_oce_latlon, tutorial_global_oce_optim & tutorial_tracer_adjsens.
2442      Keep old results by adding CD_CODE_OPTIONS.h in exp: cfc_example, exp2,
2443           global_ocean.90x40x15(+AD), global_ocean_ebm(+AD) and OpenAD.
2444    o pkg/obcs:
2445     - fix bug in initialisation (broken since Oct 1rst modification)
2446       for useOBCSprescribe without useEXF.
2447    
2448    checkpoint61y (2009/11/15)
2449    o pkg/seaice
2450     - change (once again) the discretization for the evp solver: rather than
2451       squaring the averages of strain rates, average the squares to give
2452       a better approximation to VP behavior (in simple test); this breaks
2453       verification experiments that use EVP (lab_sea and lab_sea.hb87)
2454        --> update outputs
2455    o add CPP-flag (in mom_calc_visc.F) and TAF directive (in gmredi_slope_limit)
2456      to improve vectorization of adjoint code on TARGET_NEC_SX
2457    o verification/vermix:
2458      - change vermix to a more "classical" 1d column with high vertical
2459        resolution, seasonal heat flux forcing and constant wind forcing
2460        --> update outputs
2461    o pkg/seaice
2462     - fix diagnostics of principal stress components for EVP
2463     - add optional diagnostics of non-linear convergence for LSOR solver
2464     - make maximum zeta a runtime parameter
2465    o model/src (3-d solver):
2466      Undo modif from Dec 12, 2005 (solve_for_pressure.F cvs version v.49),
2467       which consisted in removing the Surf. Non-Hydrostatic pressure from the
2468       whole column and adding it to Eta (inspired from Casualli, 1999):
2469       Only affects 3-D solver initial guess and only if using ExactConserv,
2470       but tests did show a degradation of solver convergence. For this reason,
2471       decide to disable this piece of code.
2472       to recover previous version, just set zeroPsNH = exactConserv (line 78).
2473      Update output of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW
2474    o pkg/ggl90:
2475     - fix previous modif (unfortunatly has not been documented here).
2476    o pkg/seaice/autodiff:
2477     - add CPP flag to include clipping of zeta in EVP code;
2478       although clipping of zeta is not necessary for EVP and not recommended
2479       it was done by default, now clipping is disabled by default
2480     - modify computation and store zetaC/Z in seaice_evp for TAF
2481     - add CPP-flag SEAICE_ALLOW_CLIPVELS (undefined by default)
2482     - change seaice_calc_viscosities/strainrates for better
2483       vectorization after AD by TAF
2484     - rearrange common blocks in SEAICE.h once again for easier dumps of
2485       adjoint output, adjust adcommon.h and g_common.h
2486     - change flux form of default advection scheme for better vectorization
2487       of adjoint code
2488     - modify lab_sea/input.lsr to test the flux form of default advection
2489       scheme
2490    o autodiff: fix seaice fields in g_common.h (left over from 3 to 1 level
2491      transition in checkpoint61r)
2492    
2493    checkpoint61x (2009/10/19)
2494    o adjoint: adding two new verification experiments
2495      * tutorial_global_biogeo: an online dic sensitivity experiment
2496        (work with G. Forget)
2497      * tutorial_dic_adjoffline: an offline dic sensitivity experiment
2498        (an update of the Dutkiewicz et al., 2006 paper)
2499      Both use the same CO2FLUX cost function, but different controls
2500      Gradient checks look good, but some recomp. could still be traightened out
2501      Should add xx_dic control variable to test at some point
2502    o model/src:
2503      add run-time parameters to check and/or mask initial Temp & Salt
2504    o pkg/ptracers:
2505      apply zonal filter (if used) to all passive tracers
2506    
2507    checkpoint61w (2009/10/12)
2508    o adjoint:
2509      * update and finish work on adjoint of dic package (G. Forget)
2510      * start adjoint of offline package
2511      * bug fix for cube-sphere TLM code (active_file_g.F)
2512    o tutorial_global_oce_optim:
2513      now tested with 4 tiles (change data.grdchk and update output_adm.txt)
2514      and add SIZE.h_mpi for MPI testing
2515    o pkg autodiff
2516     - fix bug in autodiff_restore
2517     - make genmake2 remove comments and empty lines from ad_input_code.f in
2518       order to reduce file size (new script file remove_comments_sed)
2519    o allows to specify vertical profile of vertical viscosity (viscArNr)
2520    o pkg autodiff
2521      autodiff_ini_model_io: comment out writing of grid information to netcdf
2522      files, because at this time the grid fields are a bunch of zeros
2523      (this is analogous to ini_mnc_vars.F)
2524    o pkg seaice/autodiff:
2525     left-over from removing the 3-time-level fields:
2526     - small rearrangement of common blocks (SEAICE.h)
2527     - fix field declaration in order to get meaningful output in
2528       adseaice.*.nc (adcommon.h)
2529    o pkg obcs:
2530     - go through NH code only if nonHydrostatic=T
2531     - fix restart for Orlanski (Hydrostatic; still to fix NH+Orlanski restart)
2532     - move call to OBCS_CALC before SEAICE_MODEL which needs seaice-obc fields
2533       => Update output of experiment seaice_obcs
2534     - useOBCSbalance: code is wrong with multi-tile / proc: add a stop.
2535     - fix NH+Orlanski restart (add wvel OBC value in pickup file)
2536     - fix restart for useOBCSprescribe + useEXF
2537    o pkg ctrl
2538     - make obcs as control parameter work also with useSingleCPUio
2539     - replace a few sny and snx by Ny and Nx to be consistent with
2540       ctrl_set_globfld_x/yz.F
2541    o pkg seaice
2542     - re-introduce global field frWtrAtm for the case of
2543       ALLOW_MEAN_SFLUX_COST_CONTRIBUTION defined (SEAICE.h, seaice_growth.F)
2544     - catch the case of an empty filename in seaice_cost_init_fixed.F
2545    o pkg ecco:
2546     - small bug fixes in the_main_loop
2547      . fix order of monitor arguments
2548      . change SEAICE_MULTILEVEL to SEAICE_MULTICATEGORY
2549      . move include DYNVARS.h up outside the ALLOW_AUTODIFF_TAMC block so
2550        that ALLOW_ECCO_FORWARD_RUN works with NONLIN_FRSURF
2551     - replace cos(yc*deg2rad) by _rA in cost_mean_heat/saltflux.F, fix the
2552       imbalance diagnostics for wmean_h/sflux = 0
2553     - add actual values to f_obcsn/s/w/e in ecco_cost_final.F
2554     - catch the case of empty filenames in ecco_cost_init_fixed.F
2555       and ecco_readparms.F
2556     - fix the logic of wsalt=0.and.wsalt2=0 to wsalt=0.or.wsalt2=0 (and theta)
2557       to make this statement meaningfull in ecco_cost_weights.F
2558    o pkg zonal_filt:
2559      - change ZONAL_FILTER S/R interface (allows to filter 2-D fields)
2560      - when using rStar, filter uVel*hFacW instead of uVel
2561       (tested without topography: fix a Pb of growing instability with NLFS)
2562    o pkg/aim/thsice:
2563     -Add capacity to read a Q-Flux to be applied in slab-mixed layer thsice_slab_ocean.F
2564      (works as SST restoring)
2565    o pkg/thsice:
2566     -add specific parameter for salt restoring in slab mixed-layer
2567       (by default equal to the temperature restoring)
2568    
2569    checkpoint61v (2009/09/21)
2570    o pkg/kpp:
2571     -add double diffusive contributions as a hack, turned off by default
2572      for now, and the code can be excluded with a CPP-flag
2573      EXCLUDE_KPP_DOUBLEDIFF just as EXCLUDE_KPP_SHEAR_MIX
2574     -add a verification experiments to "vermix" to test this code
2575    o pkg/mom_common:
2576      Move computation of length scales to mom_init_fixed.F (avoid recomputation
2577      at each time-steps*levels).
2578    o pkg/layers:
2579      Created a new package for computing volume fluxes in temperature or
2580      [not yet implemented] density layers, e.g. for calculating residual
2581      overturning circulations.
2582    o pkg/diagnostics:
2583      implement a RS type version for the set of DIAGNOSTICS-FILL subroutines
2584    o fix few RS/RL type mismatch (check with ifort 11.1 "-warn all" option)
2585    o pkg/mdsio (& pkg/rw): rework high level S/R interface:
2586      To avoid mixing type (RS/RL) of input/output array argument,
2587      replace single mixed-type array with a pair from each type (RS/RL).
2588    o setting pickupSuff force to start from a pickup (even if nIter0=0): this
2589      is now implemented for all pkgs (previously only done for the main pickup)
2590    
2591    checkpoint61u (2009/08/25)
2592    o pkg/obcs:
2593      - change OB?eta from _RS to _RL and put them into a separate commen block
2594      - add code to read OB?eta from a file via obcs_prescribe_read: the code
2595        compiles and does not destroy any other experiments, the data is read
2596        properly, but the code is not tested in actual applications
2597    o ini_mnc_vars.F: if available (ALLOW_CAL), use startTime_1 and 2 to
2598      create a meaningful unit attribute for the time coordinate variable
2599    o pkg/ebm: add plenty of missing "_d 0" ;
2600       update results of experiment global_ocean_ebm (fwd + adjoint tests)
2601      Notes: several pieces of code only works for (very) specific set up
2602       (domain size, lat range, etc ...); should be documented & stop if one
2603       of those assumptions is not meet.
2604    o pkg/seaice: add missing "_d 0" in HSNOW initialisation
2605       update results of experiments: lab_sea (3 fwd tests + 2 adjoint tests)
2606          and offline_exf_seaice (seaicetd + adjoint).
2607    o add missing "_d 0" in ShortWave flux penetration (S/R SWFRAC):
2608       update results of experiments: lab_sea (4 fwd tests + 3 adjoint),
2609        seaice_obcs, global_ocean.cs32x15 (icedyn & thsice) and natl_box (x2).
2610    o few changes to pass when compiling with strick checking of arguments
2611       across S/R (allow to find few bugs in S/R calls).
2612    o pkg/seaice:
2613     - seaice_evp: move if-statement out of loop (TEM) at the cost of 11 new
2614       2d-fields, for slightly better performance
2615    
2616    checkpoint61t (2009/07/22)
2617    o pkg/seaice:
2618     - remove unused variables in seaice_evp
2619     - reduce number of SQRT in seaice_evp and seaice_calc_viscosities
2620    o eeset_parms.F, open_copy_data_file.F & ini_parms.F:
2621       named file replacing SCRATCH files (for TARGET_BGL & TARGET_CRAYXT):
2622       each processor opens a different file (a fix from Matt).
2623    o cg2d:
2624       use simple EXCH (overlap size = 1 and ignore corners), like in cg3d.F :
2625       this reduces number of EXCH calls by 2 when using exch2.
2626       For now, keep previous size array for gc2d_nsa.F to avoid Pb with store
2627       directives and missing simple EXCH (exch_s3d_rx) adjoint code.
2628    o pkg/thsice:
2629       add code for Near Infra-Red albedo (from Jeff)
2630       (turned on with run-time flag: thSIce_calc_albNIR, in data.ice).
2631    o ini_model_io:
2632       move (from packages_readparms.F & initialise_fixed.F) to ini_model_io.F
2633       MNC & MONITOR initialisation calls; move MNC calls from {pkg}_readparms.F
2634       to {pkg}_init_fixed.F for {pkg}= kpp, seaice & shelfice.
2635    
2636    checkpoint61s (2009/06/30)
2637    o pkg/exch2 (exch2_rxN_cube*):
2638       remove last BARRIER (no need to synchronise after getting data from shared
2639       buffer (get) as long as any change to buffer (put,recv) is between BARRIER)
2640    o change tiling of natl_box (from 2 to 4 tiles) to get it tested with MPI+MTH
2641      and generate new output (for the 2 tests) using default rotationPeriod.
2642    o pkg/exch2:
2643      - always call exch2_*_cube, not exch-1 anymore, if useCubedSphereExchange=F
2644        (was already the case with AUTODIFF_EXCH2 defined)
2645      - add bj in exch2 arrays and S/R.
2646      - can now use pkg/exch2 for regular (non CS) set-up; switch test experiment
2647        MLAdjust to exch2 (identical results except with MPI -> truncation diff);
2648    o add pkg/longstep for ptracer timestep a multiple of U/V/T/S timestep
2649      - adds deltaT argument to the subroutines TIMESTEP_TRACER DWNSLP_APPLY
2650        GAD_ADVECTION GAD_CALC_RHS GAD_IMPLICIT_R GAD_SOM_ADVECT
2651      - verification experiment natl_box.longstep
2652    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
2653      allow different versions of ifort (8 or 9) and different versions
2654       of mpi (mpich or mpich2) to be used with the same optfile.
2655      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
2656       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
2657    o pkg/seaice:
2658      fix previous modif (3-level field removed) for old-pickup reading
2659    
2660    checkpoint61r (2009/06/25)
2661    o pkg/seaice:
2662     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
2663      1. introduce fields for time step (N-1)
2664      2. do not use levels 2 and 3 anymore (but keep them)
2665      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
2666         includes changes to pkg/thsice/thsice_get_velocity.F,
2667         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
2668         pkg/obcs/obcs_apply_uvice.F.
2669     - completely remove code for leap-frog time stepping for second order
2670       advection
2671     - adjusted adjoint accordingly;
2672       gradient checks have improved by an order of magnitude!
2673    
2674    checkpoint61q (2009/06/22)
2675    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
2676     - the boundary conditions along open boundaries are unclear, because the
2677       associated masks are set to zero and are thus treated as closed when
2678       applying the slip-boundary conditions.
2679     - move initialisation of grid variables from seaice_init_varia to _fixed
2680    o adding doc/diags_changes.txt
2681    o model/src:
2682      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
2683       to avoid "_diags" naming if no relation to pkg/diagnostics.
2684      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
2685       file and only call PLOT_FIELD_XYZ if debugMode=T.
2686      remove few PLOT_FIELD_XY calls outside initialisation.
2687      remove few unnecessary BARRIER.
2688    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
2689      of salt_plume package in Southern Ocean
2690    o pkg/thsice:
2691     - fix hOceMxL in overlap (needed for sea-ice advection);
2692       update output of experiment global_ocean.cs32x15.icedyn.
2693    o pkg/seaice:
2694     - make the (placeholder-)tracer IceAge a little more meaningful
2695      by avoiding ridging of age due to convergent ice flow
2696     - add diagnostics for surface temperature, atmospheric and oceanic
2697       heat flux, and atmospheric and oceanic ice growth
2698    
2699    checkpoint61p (2009/06/10)
2700    o eesupp (global_max & global_sum):
2701     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
2702     - remove starting & endding barrier (no longer needed)
2703    o pkg/mdsio, writelocal:
2704       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
2705       (remove the STOP): uses shared buffer IO to store data from all threads
2706       and then let master-thread write nThreads tiles.
2707    o pkg/mdsio (read/write field):
2708     - tiled IO done in 1 piece (all levels at a time);
2709     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
2710     - multi-threaded: allow to read/write local (non-shared) array
2711       (was already working with singleCpuIO ; now works also without);
2712       => no longer needs barrier call after reading a file (added inside
2713       mds_read/write field).
2714     - move barrier calls outside gather/scatter_2d to mds_read/write_field
2715    o pkg/obcs/exf
2716      - exf_getffieldrec.F: add a few ". _d 0" and
2717                            add code to catch the case fldperiod = 0.  
2718      - obcs_precribe_read.F: change if statements so that they match
2719                              the variable type (_RL)
2720      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
2721        exf_iprec) as part of namelist EXF_NML_01
2722    o pkg/mdsio:
2723      - read/write tiled (local) files: read/write 1-level tile chunk at a time
2724        (instead of segment of length sNx); expected to speed up tiled IO.
2725    o pkg/exch2:
2726      - take buffer copy from/to array out of S/R exch2_send/recv into new
2727        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
2728        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
2729      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
2730      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
2731        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
2732        including Topology header file (and common blocks).
2733      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
2734        remove 2nd exch call in exch2_s3d_rx (no longer needed).
2735      - document S/R arg. list (+ update some comments)
2736    o pkg/seaice:
2737      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
2738        temperature and humidity over sea ice based on climatological values.
2739      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
2740        of LSR (this change is expected to change the results slightly because now
2741        it uses slightly difference moduli from the second last LSR solution, but
2742        that is more consistent with the stress computations; this part of the code
2743        is not tested in the verification experiments)
2744      - fix diagnostics for flux of ice in case of B-grid
2745      - turn strain rates eij and press into global fields within global
2746        common block in SEAICE.h for more straighforward diagnostics
2747      - fix diagnostics for principal stress components, press, zeta, eta
2748        to give something meaning full
2749    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
2750      new output (all 4 tests) using default rotationPeriod.
2751    o pkg KPP:
2752      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
2753      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
2754        and normal grid from 1 to Nr)
2755    o Fix computations of L4rdt in mom_calc_visc.F
2756    o eesupp:
2757      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
2758      should be called before a "stop" if we know that all process are going
2759      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
2760    
2761    checkpoint61o (2009/05/26)
2762    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
2763    o model/src/ini_curvilinear_grid.F:
2764       compute angleSin/CosC when they are not read from a file
2765    o pkg/seaice:
2766       add pseudo time stepping for LSOR
2767    o pkg/exch2:
2768       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
2769    o pkg/seaice:
2770       Adding separate sea ice albedo, drag coefficients, and HO in Southern
2771       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
2772    o SingleCpuIO:
2773       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
2774    o pkg/seaice:
2775       put exchanged variable in (local) common block for MPI+Multi-Threads
2776       to work (necessary with exch1, and for now with exch2 too).
2777    o verification: to get more experiments tested with mpi, mth and mpi+mth,
2778      change tiling of:
2779       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
2780       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
2781      update output of exp:
2782       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
2783       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
2784      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
2785                       (note: output.txt generated on faulks using only 1 tile)
2786    o eesupp & mdsio (SingleCpuIO):
2787     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
2788       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
2789       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
2790     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
2791     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
2792       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
2793    o pkg/exch2:
2794     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
2795       read parameter file "data.exch2" if it exists; otherwise try default regular
2796       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
2797     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
2798       with new code (not to be used, just as a backup solution).
2799     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
2800       in utils/exch2/input.
2801    
2802    checkpoint61n (2009/05/12)
2803    o eesupp & mdsio (SingleCpuIO):
2804      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
2805        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
2806        receive real*4 array (instead of real*8) to read/write 32.bit files.
2807        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
2808         and remove new mapping S/R)
2809    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
2810      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
2811        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
2812        when using exch2. Add S/R to map global io-buffer to global model array.
2813      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
2814    
2815    checkpoint61m (2009/04/29)
2816    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
2817      and add 3 other S/R for other types (R4,R8,RS).
2818      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
2819    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
2820     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
2821     - reduce number of macro definitions (keep only those which are used);
2822       can always call directly the corrresponding S/R if needed.
2823     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
2824       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
2825     Fixed wrong type of arg in:
2826       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
2827       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
2828     To fix: global_sum of var in common block is wrong (multi-threaded) in:
2829       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
2830     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
2831    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
2832      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
2833    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
2834    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
2835      edges are closed (zero depth); might happen with "blank tiles";
2836      for now, disabled if using OBCS.
2837    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
2838      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
2839    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
2840      to reduce length of 1.D array print in STDOUT.
2841    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
2842      + use 48 tiles (16x8): this will allow to test "blank tiles".
2843    o start to test MPI + multi-threaded (change testreport to skip tests
2844      where number of tiles do not match).
2845    o genmake2: add option "-omp" to turn on Open-MP ;
2846      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
2847    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
2848      and keep the original tile numbering. Note: compatible with old
2849      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
2850    
2851    checkpoint61l (2009/04/07)
2852    o Overlaps had been forgotten in calculating ijk keys : fixed
2853    o fix cyrus makedepend for gcc 4.4
2854    o experiment fizhi-cs-aqualev20:
2855      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
2856      and generate new output. Note: new output is much closer to the old
2857      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
2858      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
2859    o pkg/fizhi:
2860     - change to avoid indices going deliberately over array-bounds
2861     - remove unnecessary MPI stuff
2862     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
2863     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
2864       does not go over array-bounds and therefore returns reliable output.
2865     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
2866       this S/R has 4 output arguments, which are used inside "get_alarm";
2867       when it is called with the same variable "ndum" in place of several
2868       output arguments, this produces weird side effect inside "get_alarm"
2869      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
2870       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
2871       address) and produces error.
2872    o tools/gemake2: (March 27-29 2009)
2873      with option "-mpi": link *_mpi files from "MODS" dir (this is what
2874      testreport does).
2875    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
2876    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
2877       update lab_sea.lsr & lab_sea.salt_plume results
2878    o pkg/seaice:
2879      Major overhaul of the LSOR solver: change discretization from original
2880      finite differences to finite volume. The old routine is still in the
2881      file seaice_lsr.F and can be turned on with the CPP-flag
2882      SEAICE_OLD_AND_BAD_DISCRETIZATION
2883      Along with this change, the discretization of the strain rates is changed.
2884      The same flag turns on the old discretization in seaice_calc_strainrates.F
2885      All verification experiments with seaice are affected (except for
2886      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
2887      results by setting the above flag.
2888      Further changes involve changes in defaults:
2889      - ALLOW_FLOODING is defined and turned on by default
2890      - SEAICEadvSnow = .true. is now the default
2891      - SEAICEadvSalt = .true. is now the default
2892      - SEAICEadvAge  = .true. is now the default
2893      - SEAICE_clipVelocities  = .false. is now the default
2894                                         (as per J. Zhang's recommendation)
2895      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
2896        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
2897      - seaice_growth: replace computation of UG by a simple copy from wspeed
2898    
2899    checkpoint61k (2009/03/18)
2900    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
2901      seaice_lsr: fixed a few metric terms,
2902                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
2903                  add more debugging diagnostics
2904      seaice_evp: removed superfluous many metric terms of FV discretization
2905                  of stress divergence
2906                  affects lab_sea, lab_sea.hb87
2907      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
2908                  of stress divergence for non-evp solver
2909                  (this part is not tested anywhere)
2910      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
2911                  they were effectively only half slip
2912                  affects lab_sea.hb87
2913      updated all relevant verification experiments (except lab_sea//output_adm.txt
2914        which was left over, but fails at level 7 & 6)
2915    
2916    checkpoint61j (2009/03/17)
2917    o pkg/seaice: turn a few hard wired parameters into run time parameters
2918    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
2919      time in seconds as promised by the usints in seaice_monitor and exf_monitor
2920    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
2921      that are not cubed-sphere grids
2922    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
2923    o pkg/ctrl:
2924      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
2925    o non-hydrostatic (calc_gw.F):
2926      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
2927      update output of exp. global_ocean.cs32x15.viscA4
2928    o remove backward compatibility for thetaMin,phiMin
2929      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
2930    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
2931      interpolated wind field not only for curvilineargrid=.true., but also
2932      for a rotated grid (rotateGrid=.true.)
2933    o pkg/exf: add capability to bypass interpolation for runoff
2934      by setting yet another CPP-flag
2935    o eesupp/src, B-grid exchange:
2936      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
2937    o autodiff
2938      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
2939      allows to switch to single-prec common blocks;
2940      corresponding switch occurs in tamc.h, integer isbyte
2941      TAF store directivs "byte" and "kind" seem equivalent;
2942      Most tamc.h have been updated correspondingly.
2943    
2944    checkpoint61i (2009/02/13)
2945    o autodiff:
2946      fix autodiff_sore/_restore indices for obcs
2947      (spotted by I. Hoteit, M. Mazloff)
2948    o pkg/autodiff, pkg/ctrl:
2949      Add flag to reduce all tapelev I/O to single-prec.
2950      In data.ctrl set
2951        doSinglePrecTapelev = .TRUE.
2952    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
2953      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
2954    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
2955      real fresh water flux (not yet)
2956    o pkg/mdsio & rw:
2957     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
2958     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
2959    o pkg/flt:
2960     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
2961       init_fixed & ini_varia.
2962     - clean-up & simplify linear interpolation S/R:
2963       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
2964     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
2965     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
2966     - add vert. coordinate & horiz. indices to output files.
2967     - change vertical position in initial condition, from index to depth [m].
2968     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
2969       (easier to get to a curvilinear grid) ; delX,delY no longer used.
2970    o pkg/ggl90: a few modifications:
2971     - fix bottom boundary condition, and interpolation of KappaE
2972       near top and bottom
2973     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
2974     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
2975     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
2976    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
2977      (maintain temporary backward compatibility, until next checkpoint)
2978    
2979    checkpoint61h (2009/01/27)
2980    o pkg/diagnostics with "periodic averaging diagnostics":
2981      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
2982    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
2983    o pkg/obcs: fix loop ranges for balancing code
2984    o pkg/flt:
2985     - improve criteria for finding which tile owns a float.
2986     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
2987    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
2988      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
2989      with ocean biogeo)
2990    o pkg/flt:
2991     - do some cleaning and fix the restart ;
2992     - add output.txt in flt_example/results to get this pkg tested.
2993    o genmake2: add an EXTENDED_SRC option and flag.
2994       for now, cannot be turned on on command line (only through genmake_local)
2995    o pkg/mdsio: read/write vector:
2996     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
2997     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
2998       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
2999     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
3000      (drop to 4 digits matching for grad). But this test does not look very
3001      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
3002    
3003    checkpoint61g (2008/12/29)
3004    o pkg/flt:
3005      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
3006       + make OPTIONS file more standard.
3007      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
3008      - fix _BYTESWAPIO CPP-Flag
3009      - standard reading of file-parameter "data.flt"
3010      - fix argument list of S/R FLT_RESTART
3011      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
3012    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
3013    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
3014      a still unfixed compiler/optimization bug
3015    
3016    checkpoint61f (2008/11/21)
3017    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
3018      update results of global_ocean.cs32x15.icedyn test.
3019    o move getcon.F from model/src to pkg/fizhi.
3020    o pkg/exf: add parameter for extrapolation of temp up to the surface
3021       and option to prevent negative evap (in bulk_largeyeager04 only).
3022    o Prather Advection scheme: fix tracer conservation for divergent flow
3023      (e.g., when using NonLin Free-Surface).
3024    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
3025    o gmredi (Visbeck-variable-K):
3026     - add more parameters to Visbeck-variable-K.
3027     - use a 5 points average for dSigmaR in Visbeck-K calculation
3028       (more "homogenous": same stencil and same weights as in dSigmaH)
3029     - update output of ideal_2D_oce experiment.
3030    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
3031      (#undef REAL4_IS_SLOW)
3032     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
3033       coordinate variable
3034     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
3035       (surface forcing fields), removes some of the functionality
3036     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
3037     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
3038       probably not all: copy _RS surface flux fields to RL field before
3039       calling DIAGNOSTICS_FILL
3040     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
3041       real*4 (CALL EXCH_*_RS) versions.
3042     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
3043       (generate new output).
3044    
3045    checkpoint61e (2008/10/23)
3046    o gmredi (Visbeck-variable-K):
3047      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
3048      - change computation of Visbeck-K where Slope > Smax :        
3049        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
3050        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
3051    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
3052      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
3053    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
3054    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
3055      does not become too large (to avoid precision problems in implicit-diffusion
3056      solver); update ideal_2D_oce output.
3057    o pkg ggl90:
3058      - in ggl90_cal.F: compute only one set of visc/diff, used to
3059        step forward TKE/T/S/momentum
3060      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
3061        have Prandlt =1)
3062    o gmredi (fm07):
3063      - add lower limit on Transition layer thickness + lower limit on 1/lambda
3064      - allow to set few more params from data.gmredi
3065    o pkg ggl90:
3066          - add missing sqrt(2) factor in computation of mixing length
3067            scale in ggl90_calc.F
3068            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
3069    
3070    checkpoint61d (2008/09/25)
3071    o adjoint modifs
3072      - adapt to new field rhoInSitu
3073      - allow to revert from StoreDynVars2D, StoreDynVars3D
3074        to individual fields
3075        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
3076    o store 3-D (in-situ) density in commom block (DYNVARS.h)
3077     - save 1 rho computation.
3078     - no longer modify T & S inland when using down_slope pkg.
3079    o gad_som : allow to switch to SOM advection for T & S without corresponding
3080      pickup files (using new S/R: MDS_CHECK4FILE).
3081    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
3082      (for useSingleCpuIO to work in multi-threaded)
3083    o pkg/shelfice:
3084     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
3085       with SHELFICEtopoFile in data.shelfice
3086     - move code for reading ice shelf topography and modifying hFacC into separate
3087       subroutines of the shelfice package
3088     - separate initialisation of "fixed" and "variable" variables
3089     - kTopC is not (yet) replaced by kSurfC, although this is possible
3090    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
3091    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
3092      and rename:
3093      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
3094      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
3095    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
3096    
3097    checkpoint61c (2008/08/30)
3098    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
3099      to add mass source/sink of fluid in the interior (3-D generalisation
3100      of oceanic real-fresh water flux).
3101    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
3102    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
3103    o new pkg: down_slope
3104      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
3105      - presently, modify T & S inland (dwnslp_calc_rho.F).
3106        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
3107      - implementation for ocean in P-coords not tested.
3108      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
3109    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
3110      (to facilitate conversion of oceanic pkg to p-coordinate).
3111    o change FIND_RHO to FIND_RHO_2D :
3112      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
3113    o new pkg: cheapaml
3114    
3115    checkpoint61b (2008/08/05)
3116    o exch2:
3117      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
3118      - no longer depend on the order sequence (N,S,E,W).
3119      - 3rd exchange no longer needed (tested with 24 tiles).
3120      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
3121      - exch_UV_A-grid readily available (but not yet tested).
3122      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
3123      (both are no longer needed) in exch_uv: no effect in forward run; but
3124       get truncation error differences with adjoint exch.
3125    o exch2:
3126     - change index-bounds storage (moved from target to local tile,
3127       more intuitive this way) ; rename/remove some variables.
3128     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
3129    
3130    checkpoint61a (2008/07/29)
3131    o exch2/matlab-topology-generator:
3132      fix bug in index bounds for N-S internal exchange (hard to tell if this
3133      had any effect on the solution).
3134    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
3135      is exceeded
3136    o testreport: modify syntax of awk, so that it works also with
3137      awk, and not only with nawk and gawk
3138    
3139    checkpoint61 (2008/06/24)
3140    o autodiff
3141      Change default for TAF usage by removing argument '-nonew_arg'
3142      This changes TAF subroutine argument list (ordering of active var.)
3143      Omission of this flag leads to incompatibility w.r.t. TAMC
3144      To restore TAMC-compatibility, need following modifs:
3145      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
3146      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
3147      Tested TAF version is 1.9.22
3148      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
3149    
3150    checkpoint60 (2008/06/19)
3151    --->>> This is the last checkpoint for which generating the adjoint
3152    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
3153    --->>> by default.
3154    --->>> Future checkpoints will ommit this flag by default.
3155    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
3156    o pkg/grdchk: Add gradient check to etan0 perturbations.
3157    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
3158    o pkg/autodiff: more flexibility in zeroadj.
3159      model/src: modifying do_oceanic_phys.F accordingly.
3160    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
3161    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
3162      special setup of gmredi for which the adjoint is stable
3163      enough for parameter optimization.
3164    o bridging the gap between eddy stress and GM.
3165      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
3166          along with a change in CPP option (now ALLOW_EDDYPSI).
3167      -> when using GM w/ GM_AdvForm:
3168          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
3169          is applied either in the tracer Eq. or in momentum Eq.
3170          depending on data.gmredi (intro. GM_InMomAsStress).
3171      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
3172      The key modifications are in model/src/taueddy_external_forcing.F
3173      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
3174    
3175    checkpoint59r (2008/05/29)
3176    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
3177      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
3178      fix option to read coriolis(@ cell-corner) from files with CS-grid.
3179    o pkg/mnc: add some attributes to standard 1D-coordinate variables
3180    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
3181      mass points, when using mnc for output
3182      - add runtime parameter (missing_value, missing_value_int) to override
3183        default (which is the value of getcon('UNDEF'))
3184    o pkg/mnc: prepare mnc for the actual use of missing values with the
3185      diagnostics package: small fix in mnc_cw_readwrite.template and more
3186      initialisation of never used fields
3187      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
3188      versions
3189    o pkg/thsice/thsice_ini_vars.F added default initial values so that
3190      thermodynamics sea ice solver does not blow up when some initial fields
3191      are missing.
3192    o move from external_forcing_surf.F to ini_forcing.F
3193      the p-coord. hack consisting in using pLoad to set phi0surf ;
3194      update output of tutorial_global_oce_in_p (affected @ truncation level).
3195    o Freshen up a bit hs94.1x64x5, notably:
3196      remove rotationPeriod and tRef=5*0. (adjoint only), and add
3197      exactConserv=.TRUE.
3198    o pkg/generic_advdiff:
3199      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
3200      applies to files where Temperature & Salinity 2nd Order moments are used.
3201    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
3202      this uses a dynamically allocated internal state data structure
3203      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
3204      and requires a fortran 90 compiler
3205    
3206    checkpoint59q (2008/05/06)
3207    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
3208       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
3209    o Refresh tutorial_global_oce_biogeo, notably:
3210      - change bathymetry (put back seamounts in ACC, use hFacs)
3211      - change EOS (POLY3 --> JMD95Z)
3212      - use Bryan-Lewis vertical diffusivity
3213      - use multidimensional advection
3214      - remove old virtual virtual in dic pkg, now done through ptracer pkg
3215      - change a couple of parameters in dic pkg
3216    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
3217    o pkg/obcs: change default to OBCSfixTopo = .true.,
3218      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
3219      - replace "debugMode" with "debugLevel .GE. debLevB"
3220    o implementation of TAF directives for gchem,cfc,dic
3221    o remove "exp5" (replaced by tutorial_deep_convection).
3222    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
3223      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
3224      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
3225      --> changes results in exp4, seaice_obcs
3226    o tutorial_deep_convection :
3227      update the set-up and increase resolution and domain size ; start
3228      from pseudo initial conditions = output at t=120mn in order to see
3229      something happening when running testreport.
3230    o pkg/seaice: add os7mp as an advection scheme
3231                  add check for advection schemes
3232                  add a flag for restoring T and S underneath sea ice
3233    o pkg/my82: add netcdf-support and diagnostics
3234    o thsice pkg:
3235      - Now hsMax limits snow height by turning it into ice following
3236        flooding scheme (and now conserving energy)
3237      - Slight rewriting of the formula in thsice_calc_thick.F
3238      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
3239      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
3240    
3241    checkpoint59p (2008/04/10)
3242    o gchem / dic / cfc :
3243      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
3244      - add new parameter files: "data.dic" & "data.cfc" ;
3245      - various re-arrangement in initialisation & header file ;
3246      - fix tutorial_global_oce_biogeo for multi-threaded test.
3247    o pkg/dic: test for "pickup_dic" file when restarting ;
3248      if no pickup-file, can restart with a re-initialised pH (same as it did
3249      before) providing pickupStrictlyMatch is set to False.
3250    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
3251      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
3252    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
3253      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
3254    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
3255     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
3256       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
3257    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
3258       scheme to use for vorticty-term ;
3259     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
3260       (with default selectVortScheme, return to original discretisation)
3261     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
3262    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
3263    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
3264      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
3265      also fix diagnostics VISCAHW & VISCA4W.
3266    
3267    checkpoint59o (2008/03/07)
3268    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
3269    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
3270      move a few statemens out the main loop into separate loops
3271    o pkg/shelfice:
3272      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
3273        (kg/m^2/s), does not break tests, because in verification/isomip,
3274        rhoConstFresh=rhoConst (by accident)
3275      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
3276      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
3277        new file model/src/seawater.F, so that they are available for all pkgs.
3278      - convert potential temperature into in-situ temperature. This changes the
3279        isomip tests => update tests
3280    o add a flag writePickupAtEnd (default=true) to be able to suppress
3281      writing a pickup at the last timestep
3282    o tools/mpack-1.6 :
3283      - disable automake (not working) and autoconf (not needed).
3284      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
3285        also cleaner with much less compilation warnings.
3286    o pkg/profiles:
3287      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
3288      (for "less than 32 characters name" compiler requirement)
3289    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
3290      conditions that have a different sampling frequency than S/T/U/V obcs
3291    o pkg/diagnostics (stats-diags):
3292      - fix global Min/Max in case 1 processor get only empty tiles
3293    o genmake2: replace (4 times)
3294         make genmake_tc_1.o >> genmake_warnings 2>&1
3295      with
3296         COMM="$CC $CFLAGS -c genmake_tc_1.c"
3297         echo $COMM >> genmake_warnings
3298         $COMM >> genmake_warnings 2>&1
3299      to make genmake2 always see the value of CC as specified in the optfile.
3300    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
3301      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
3302      - modify verification advect_cs test to test SOM-advection on CS-grid.
3303    o pkg/ctrl:
3304      - Rewrite of ctrl_map_ini_ecco.F,
3305        introducing a generic routine (ctrl_map_ini_gen.F).
3306      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
3307    
3308    checkpoint59n (2008/02/09)
3309    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
3310      number in dedicate array "hdiag":
3311      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
3312        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
3313      - many small changes (integer format) for large number of diagnostics
3314      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
3315        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
3316    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
3317      usingSphericalGrid, this allows to define the rotated grid coordinates
3318      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
3319      geographical coordinates according to the inverse of the rotation defined
3320      by the Euler angles, so that Coriolis parameter and online-interpolation by
3321      exf works with the geographical coordinates on XC/YC/XG/YG.
3322      Naturally, this feature does not work with all packages, so some
3323      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
3324      profiles), because there the coordinates are assumed to be regular
3325      spherical grid coordinates.
3326    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
3327      - introduce isopycnal diffusion coefficient control.
3328    o tools/adjoint_options:
3329      - additional control vector components.
3330    o pkg/mnc: have mnc create marginally meaning full coordinate variables
3331      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
3332    o pkg/mypackage:
3333      - add example of read/write pickup for state-var ;
3334      - add entry points to the main code for state-vars diags & write-pickup.
3335    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
3336      transitions for useExfYearlyFields
3337      - add new subroutine that determines the file to read from for
3338        use*YearlyFields = .TRUE. and .FALSE.
3339      - add a verification experiment to global_with_exf that tests
3340        useExfYearlyFields with USE_EXF_INTERPOLATION defined
3341    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
3342      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
3343      subroutines (which could be generated from a template, because they are
3344      almost identical), for now they are included in obcs_prescribe_read.F for
3345      simplicity
3346    o pkg/exf:
3347      - add a little more diagnostic to exf_interp_read (in analogy to
3348        mds_read_field, can be turned off with debugLevel < debugLevA=1)
3349      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
3350        ugly but fast by unrolling short inner loops, inserting a unroll=8
3351        directive in routine lagran, and splitting a loop and making do while the
3352        outermost loop (the latter requires the intoduction of index arrays)
3353    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
3354    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
3355      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
3356    o verification/seaice_obcs: updated for restart test and latest options
3357    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
3358      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
3359      for now this is only available for the C-grid code and also within
3360      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
3361    
3362    checkpoint59m (2008/01/14)
3363    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
3364      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
3365    o gad_som : fix flux output (& diagnostics) to have same units as other  
3366      advection scheme fluxes (was previously multiplied by deltaT).  
3367    o added verification/seaice_obcs both to test seaice open boundaries
3368      and to provide an example matlab scrpt for generating them
3369    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
3370    o pkg/salt_plume: clean up salt_plume_frac.F to
3371      remove redundancy in PlumeMethod 1 and 4
3372    o pkg/kpp: added saltplume diagnostics
3373    o pkg/obcs and pkg/seaice:
3374      - do not set uice and vice to zero when OB*icefile are unspecified
3375      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
3376      - moved seaice tracer obcs after call to seaice_growth
3377    o pkg/salt_plume: added various options for salt plume depth
3378      criterion and for vertical distribution of the salt
3379    
3380    checkpoint59l (2007/12/18)
3381    o pkg/ptracers: new version of ptracers pickup:
3382      read meta file and write only fields which are needed to restart.
3383      ( same logic as main pickup file ; also using pickupStrictlyMatch )
3384    o pkg/seaice:
3385      - add timescale for melting due to warm mixed layer as a means of
3386        setting SEAICE_availHeatFrac more conveniently
3387      - add a CPP-flag/runtime parameter check for flooding algorithm
3388      - reformulated availHeat in seaice_growth.F to be independent of AREA
3389    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
3390      unit changes
3391    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
3392    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
3393      SX vector computer.
3394    o pkg/seaice:
3395      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
3396        seaice forcing fields can now be read only through pkg/exf
3397      - removed some unused halos
3398    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
3399    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
3400      or U/VICE from U/VWIND before computing U/VSTRESS
3401    
3402    checkpoint59k (2007/11/30)
3403    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
3404      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
3405    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
3406      all experiments pass when compile with un-initialised var. checking option.
3407    o added pkg/salt_plume
3408    o script to test restart (for now, in MITgcm_contrib/jmc_script)
3409    o pkg/seaice: new read/write pickup version.
3410      read meta file and write only fields which are needed to restart.
3411      ( same logic as main pickup file ; also using pickupStrictlyMatch )
3412    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
3413    o lab_sea.hb87: modify the domain & update output.hb87.txt :
3414      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
3415      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
3416      process. Fixed here by closing the domain at the Northern boundary.
3417    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
3418    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
3419      a set of consecutive levels in/from a 3-D array.
3420    o pkg/ptracers:
3421      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
3422      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
3423    
3424    checkpoint59j (2007/11/09)
3425    o in pkgs: dic, obcs, offline, rbcs:
3426      standard way to compute coeff. for time interpolation between 2 time reccords
3427      which retains full precision (& make results less dependent on compiler).
3428      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
3429    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
3430      packages instead of reading ice cover and wind speed separately
3431    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
3432     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
3433      to allow to compile customized code before the update)
3434    o cleaning-up:
3435      - fix CPP instruction syntax in pkg/obcs
3436      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
3437        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
3438      - fix some threads issue in IO parts.
3439    o pkg/dic:
3440      - add tons of "_d 0" (--> much better testreports !)
3441       and then update outputs of tutorial_global_oce_biogeo
3442    o pkg/mom_fluxform:
3443      add a special version of momentum advection intended to conserve momentum
3444      next to a bathymetry step or a coastline edge. (default = off = #undef)
3445    o new read/write pickup version:
3446      - for now, only implemented for main (mdsio) pickup file.
3447      - write out only what is needed to restart; merge pickup_nh , pickup_ph
3448        and main pickup together.
3449      - read meta file; read only what is needed to restart; stop if a field
3450        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
3451        if it make sense (even if the restart is not perfect).
3452      - if no meta file, assume that pickup to read corresponds exactly to
3453        a pickup that would currently be written.
3454      - read pickup written in the old format (until checkpoint59i) if it
3455        recognizes an old meta file (no field-list).
3456      - add a meta file in exp. which starts from a pickup: 2 cases:
3457        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
3458         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
3459        b) a meta file describing the content of the associated pickup file
3460         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
3461    o pkg/mdsio & pkg/rw:
3462      - new routine to read a meta file ; new set of routine to read
3463        Multiple-fields file (with meta file).
3464    o added open boundary conditions capability for seaice
3465        HSNOW, HSALT, UICE, and VICE
3466    
3467    checkpoint59i (2007/10/21)
3468    o adjoint:
3469      * fix multiDimAdvection adjoint
3470        (partial recomputation problem by TAF for fVerT(:,:,kDown)
3471        and comlev1 size definition (maxpass vs. max. number of tracers)
3472      * verification/global_ocean.90x45x15 adjoint now tests
3473        NLFS and multiDimAdvection using DST3 (=30)
3474      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
3475    o pkg/kpp: add "_d 0" to real constant (if missing);
3476      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
3477      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
3478    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
3479      for internal parameters related to restart process (formerly from PARAMS.h)
3480      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
3481    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
3482      as argument. (only atm2d & obcs write_pickup have not yet been updated)
3483    o pkg/monitor:
3484      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
3485      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
3486      - account for deep Atmosphere factor and density factor (anelastic)
3487    o added open boundary conditions capability for seaice HEFF and AREA
3488    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
3489      thermodynamics
3490      - requires a little reorganization, which affects the testreport results
3491        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
3492        so that now the conservative form is tested
3493      - add a few comments
3494    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
3495    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
3496    o add new diagnostics to seaice: advective, diffusive fluxes (only for
3497      multidim-advection, for scheme 2 they are not filled) and transports,
3498      thermodynamic growth rates
3499    o change units of EmPmR (inside the code, + within coupling interface)
3500      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
3501      Affects results @ truncation level (cg2d match) and update output of
3502       experiments: lab_sea(6), global_ocean.90x40x15(10),
3503      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
3504      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
3505      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
3506      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
3507    
3508    checkpoint59h (2007/09/29)
3509    o pkg/exf:
3510      - improve vectorization by moving if-statement out of loops in
3511        exf_mapfields, exf_radiation
3512      - exf_bulkformulae.F: introduce 2D fields and vectorize code
3513    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
3514    o testreport:
3515      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
3516        monitor & update offline_exf_seaice exp. output.
3517      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
3518    o pkg/seaice:
3519      - bug fix in the evp solver: boundary conditions were affected be
3520        masking of zMax/zMin (changes results)
3521      - minor bug fix in boundary conditions in seaice_calc_strainrates
3522        (changes results for no_slip)
3523      - seaice_lsr.F: make interpolation of eta dependent on boundaries
3524      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
3525      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
3526        stress formulation and no-slip boundary conditions
3527    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
3528      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
3529    o pkg/seaice: a first HSALT time stepping equation has been checked in
3530    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
3531      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
3532      without requiring DO-IF statements
3533    o pkg/thsice:
3534      use continuous power-law function for partition of energy between lateral
3535      melting/freezing and thinning/thickening ; old code using step function
3536      still available with #undef THSICE_FRACEN_POWERLAW
3537      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
3538    o testreport: change AD testing : check against results/output_adm.txt
3539      using same scripts as for forward test.
3540    
3541    checkpoint59g (2007/09/17)
3542    o adjoint testing: in preparation for changing testreport:
3543      - output format: cost and grad written on separated lines
3544      - ad output results in directory "results" (instead of "results_ad")
3545    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
3546    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
3547    o pkg/ecco: allow user defined cost function contributions
3548    o testreport:
3549      Allow to choose (per experiment) the list of tested output variables
3550       and the main variable (used to issue a pass/FAIL ) ;
3551      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
3552      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
3553      Also modify printing of summary:
3554       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
3555       b) echo the list of tested variables in the individual summary.txt of
3556          each experiment.
3557    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
3558      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
3559      (but still depend on the tile decompostion of the domain).
3560    o pkg/seaice: change a discretization detail to make the B-grid code
3561      "more symmetric". This change is likely to remove all "ridges/leads" that
3562      where quasi-aligned with the grid in B-grid solutions. It may also be
3563      the solution to the stress coupling issues with the B-grid.
3564    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
3565      remove .cvsignore from input dir. (since testreport no longer run here).
3566    o pkg/thsice:
3567     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
3568     - fix reshaping of sea-ice just after advection:
3569       melt all the ice only if ice-volume is too small.
3570     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
3571       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
3572     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
3573    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
3574      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
3575    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
3576      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
3577      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
3578      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
3579      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
3580      -> update output.txt
3581    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
3582     this affects truncation error: -> update output.txt of exp:
3583      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
3584      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
3585    
3586    checkpoint59f (2007/08/21)
3587    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
3588    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
3589      a bounded range (in forward mode)
3590    o pkg/ecco, ctrl, autodiff and mom_common:
3591     internal parameter controls, completements of implementations
3592    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
3593    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
3594      (not seem any difference in testing results).
3595    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
3596       at face corners.
3597    o pkg/generic_advdiff:
3598     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
3599      loop range indices for computing vertical advection tendency
3600      and do the calculation in the interior only (no overlap) ;
3601      for now, only implemented for SOM advection (to save CPU time).
3602     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
3603    o exch2 adjoint
3604      First set of changes:
3605      - add exch2 hand-written adjoint templates
3606      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
3607        This will require cleanup in pkg/autodiff/*.F
3608        (changed routines currently kept separate in verif. code/)
3609      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
3610        that used to hide exch2 or cubed-sphere specific code
3611        (commented via 'cph-exch2')
3612    o pkg/seaice
3613      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
3614    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
3615       output of global_ocean.cs32x15.thsice .
3616    
3617    checkpoint59e (2007/07/26)
3618    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
3619      for B-grid vector (not yet tested) and C-grid vector (<- only used
3620      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
3621    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
3622      (#ifdef ALLOW_SALT_PLUME)
3623    o gather_2d/scatter_2d: removed halo regions
3624    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
3625      scheme and the corresponding test case (under front_relax dir). For now,
3626      only available with Skew-flux form and not yet tested in realistic set-up.
3627      adjoint: store directives updated, but gradient checks deteriorated,
3628      so maybe GM/Redi adjoint is now broken.
3629    o seaice adjoint
3630      * add AREA, HEFF, HSNOW as control variable
3631        (should not change lab_sea results)
3632      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
3633    o pkg/seaice:
3634      * added computation of saltFlux in seaice_growth;
3635        For time being, sea ice salinity is assumed constant
3636        contribution of snow flooding to freshening of sea ice is neglected.
3637        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
3638        defaults to 0.0 in order to maintain backward compatibility.
3639        Typical values for SEAICE_salinity are 4 to 10 g/kg.
3640      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
3641      * added SEAICE_availHeatFrac, which specifies fraction of surface level
3642        heat content used to melt or grow ice
3643      * commented out cap of HICE: it helps keep ice thinner
3644      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
3645      * applied OBCS T/S mask to HEFFM sea ice mask
3646    
3647    checkpoint59d (2007/06/21)
3648    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
3649     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
3650     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
3651    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
3652     and change default value of parameter "GM_Small_Number";
3653     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
3654       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
3655       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
3656    o pkg/ecco: cost function when applying pkg/smooth to controls
3657    o pkg/ctrl: add forcingPrecond run time parameter
3658    o pkg/seaice:
3659     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
3660     - fix bug in metric terms of u-equation in LSR solver (implicit part),
3661       changes verification/lab_sea
3662     - rearrange implicit part of u-equation in LSR solver to make it easier to
3663       read, understand, and debug. This causes changes at the truncation level.
3664     - fix (serious) bug in the boundary conditions (sign error in the implicit
3665       part) of the LSR solver. Changes all LSR results.
3666     - fixed problem with HSNOW initialization to avoid thick snow when AREA
3667       is initilized with small values - does not change lab_sea results.
3668     - added HsnowFile initialization capability
3669    o pkg/smooth: addition to model/src and pkg/ctrl so allow
3670     initialization of pkg/smooth and application to control vector
3671    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
3672    o dependencies: pkg/profiles requires pkg/cal
3673    o pkg/profiles:
3674     - added option ALLOW_PROFILES_GENERICGRID
3675         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
3676         that interpolation information (grid points and coefficients) is provided
3677         within the netcdf input files.
3678         -> sample matlab scripts can be found in MITgcm_contrib/gael
3679         that allow you to prepare netcdf input files.
3680     - also modified: cleaner include statements, cleaner error print statements,
3681       cleaner stops when error, and more tests of the netcdf input files consistency.
3682    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
3683    o pkg/seaice:
3684     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
3685       requires a new routine: seaice_diagnostics_fill.F
3686     - make sure that seaice does not move if not forced (pressure replacement
3687       method, Hibler and Ip, 1995), changes results
3688     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
3689     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
3690       It is turned off by default (=-1.), because it changes the results.
3691     - make it possible to read AREA from a file, too.
3692    
3693    checkpoint59c (2007/06/04)
3694    o add S/R and diagnostics for oceanic mixed-layer depth
3695    o move GMRedi call after all vertical mixing schemes (including KPP)
3696    o pkg/thsice:
3697     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
3698      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
3699    o pkg/obcs:
3700     - bug fix for balance code
3701    o pkg/seaice:
3702      - allow values of SEAICE_elasticParm > 1
3703      - add new parameter SEAICE_evpTauRelax as an alternative
3704        to SEAICE_elasticParm
3705      - make lsr boundary conditions free slip (by default), changes result
3706      - add code for no slip boundary conditions for lsr
3707      - set minimum of zeta to zero (and not 4e8) (changes results)
3708      - add a cap on AREA after advecting AREA if seaice_growth is not called
3709    o change calculation of Visbeck K:
3710      - no longer depend on tapering scheme; instead, compute slope (limited
3711        by GM_maxSlope). this is equivalent to what was comuted before with
3712        clipping or linear tappering.
3713      - fix vertical averaging (wrong by 1/2 level)
3714      - leave the old version (but will not be maintained) within
3715        #ifdef OLD_VISBECK_CALC / #endif
3716      - update output of exp. ideal_2D_oce
3717    o change error catch in calc_r_star to improve vectorization
3718    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
3719      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
3720    o adjoint:
3721      Re-organized adjoint checkpointing according to Matt Mazloff
3722      (but with modifs/completions/cleanups)
3723      Storing is now bundled into large arrays to optimized I/O
3724      (and second step in cleanup of the_main_loop)
3725    
3726    checkpoint59b (2007/05/16)
3727    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
3728      - export/import (between ocean & coupler) fields needed for ocean DIC.
3729    o pkg/seaice:
3730      - get rid of three more exchanges seaice_calc_viscosities (required
3731        different loop boundaries in seaice_lsr and seaice_ocean_stress)
3732      - bug fix in seaice_ocean_stress (update of lab_sea required)
3733      - reduce loop boundaries to necessary minimum also in seaice_evp
3734      - go back to the old way of computing deltaC/Z as the adjoint likes that
3735        better
3736    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
3737      passive tracer to an Age Tracer) + update output.txt
3738    o pkg/exf:
3739      - implement A-grid / C-grid selection for wind-stress input files.
3740      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
3741      for now, in exf_bulk_largeyeager04.F only :
3742      - change implementation for case where windspeed + 2. components wind-stress
3743        are read-in. AND use rhoConstFresh to convert evap.
3744    o pkg/seaice:
3745      - use correct EXCH_UV for wind-forcing (on A-grid).
3746      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
3747        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
3748    o pkg/exf:
3749      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
3750      EXF_INTERPOLATION:
3751      - merge global_with_exf/code version of exf_interp_read.F
3752        to the main code ;
3753      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
3754        reading the file ; Important: This options needs to be defined to recover
3755        previous code.
3756        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
3757      - no longer loose real*8 precision along the way when using exf_iprec=64.
3758    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
3759      - change discretisation of evp-solver in order to avoid another exchange
3760        (changes lab_sea) and clean up a little
3761      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
3762        help the adjoint (this also changes the results slightly)
3763      - add a few "_d 0" where they had been missing in seaice_evp.F
3764      - cleaning up: remove unused seaice_calc_rhs.F
3765    o pkg/exf: some cleaning-up:
3766      - change various "constants" into runtime parameters
3767      - cleaned-up Large&Yeager04 routine which should eventually
3768        replace exf_bulkformulae.F (changed names of S/R and CPP)
3769        and merged various ALLOW_ATM_WIND options
3770     only used with thsice pkg (in thsice_get_exf.F):
3771      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
3772        which are used when useStabilityFct_overIce=TRUE (= the default)
3773      - change default values of ice & snow emissivity and scale downward LW
3774        by ice & snow emissivity.
3775    o pkg/thsice:
3776     fix few little problems, in thsice_calc_thickn.F:
3777      - growth vertically (and not laterally) if iceFrac == iceMaskMax
3778      - melt only laterally if hIce < hThinIce (as the comments say)
3779      and in thsice_extend.F:
3780      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
3781      - start to form ice as soon as the minimum ice-volume is reachable.
3782     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
3783      and cpl_aim+ocn
3784    o pkg/kpp
3785     - move computation of surface related input fields to KPP into a new
3786       subroutine kpp_forcing_surf.F
3787     - remove wrong (within bi,bj loops) EXCH calls.
3788     - little cleaning (add argument myThid in last position, cvs header ...)
3789     - for now, fix conservation problem by exchanging KPPviscAz (may not
3790       be the best fix)
3791    o pkg/seaice
3792     - check for inconsistent evp parameter/cpp-flag combination
3793     - remove leftover errIO flat for obsolete name list error handling
3794    o OpenAD
3795     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
3796    
3797    checkpoint59a (2007/05/01)
3798    o pkg/seaice: some parameter clarifications and a little bit of clean up
3799    o pkg/thsice: rename run-time parameters:
3800       himin       -> hIceMin
3801       himin0      -> hThinIce
3802       hihig       -> hThickIce
3803       i0          -> i0swFrac
3804       transCoef   -> bMeltCoef
3805       frac_energy -> fracMelting
3806      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
3807       with default values (for now) that do not change the results.
3808      remove old version of thsice vars advection in pkg/seaice.
3809    o in FFIELDS.h:
3810      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
3811      - make pLoad & sIceLoad always available (but still only used if
3812         ATMOSPHERIC_LOADING is #define).
3813    o pkg/kpp: replaced _KPP_RL with _RL
3814    o bug fixes for vertical diffusivity computations when both KPP and
3815        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
3816        are no longer updating the vertical diffusivity array
3817        (passed as argument) but are (re-) setting those arrays.
3818    o pkg/seaice: fix bug in evp solver, while doing that
3819      - change (improve?) discretization of stress computations for both
3820        cgrid-lsr and evp solver
3821      - add a new routine to compute strain rates
3822      - the above changes lab_sea results
3823      - add no slip conditions for evp solver (off by default), lsr-version
3824        may follow
3825      - fix exchange for shear at Z-points (does not change lab_sea)
3826      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
3827        (to force the user to pick a time step since there is not "safe" way
3828        of choosing it)
3829      - add principal stress diagnostics
3830      - rearrange fields for evp a little to avoid having to call a: too many
3831        exchanges and b: exchanges for stress trensor components which we do
3832        not have.
3833      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
3834        of evp, complete rewrite for lsr case (latter is does not yet work
3835        in all cases)
3836    o pkg/kpp: add code to have mixing in shelf ice caverns
3837      - add myThid to all kpp routines (long overdue)
3838    
3839    checkpoint59 (2007/04/19)
3840    o pkg/exf:
3841      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
3842        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
3843      - move exf header files from lower_case.h to UPPER_CASE.h ;
3844        add missing cvs Header & Name
3845      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
3846      - add namelist param. selectStressGridPosition, exf_monFreq
3847      - retire many _CLIM routines, and remove data.exf_clim
3848        + params moved to data.exf
3849        + climsst, climsss now handled by exf_set_gen, i.e.
3850          climss?period=0 refers to constant field,
3851          climss?period=-12 to monthly forcing
3852      - split up namelists in data.exf
3853    o pkg/seaice:
3854      - remove seaice_exch and seaice_exch_uv
3855      - remove superfluous exchange of theta
3856      - add myThid to seaice_budget_ocean/ice
3857      - add new interface for atmospheric wind forcing (C-grid only)
3858        + new routine
3859        + two new field (taux, tauy for stress over ice)
3860        + removed one global field (DAIRN) for C-grid case only
3861    o pkg/thsise
3862      - 2nd set of modifs for thsice adjoint in conjunction with exf
3863    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
3864    
3865    checkpoint58y_post (2007/04/15)
3866    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
3867      vertical diffusivity, similar to that in MOM4; turned on using
3868      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
3869      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
3870    o Added capability for 3D specification of background vertical diffusion
3871      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
3872      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
3873      "data" file that contains the 3D vertical diffusivity coefficients.
3874    o ice dynamics (pkg/seaice) with thsice thermodynamics:
3875      - add code within pkg thsice to advect & diffuse sea-ice fields
3876      similar to (and will replace) what has been added in  seaice_advdiff.F,
3877      but: - conserving Mass, Heat & Salt.
3878           - better when using non-linear advection scheme (not yet fully tested)
3879           - can also be used in atmospheric set-up (for now, only the diffusion).
3880    
3881    checkpoint58x_post (2007/04/04)
3882    o IO option for global-file compact format:
3883      - add options when generating topology (utils/exch2/matlab-topology-generator)
3884      - add I/O capability (pkg/mdsio).
3885      - adapt utils/matlab/rdmds.m to read this format.
3886      for now long-line format not yet supported by pkg/mdsio (& exch2).
3887    o shelfice: add a few diagnostics
3888    
3889    checkpoint58w_post (2007/03/13)
3890    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
3891      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
3892      (and replace horiVertRatio in NH code).
3893      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
3894                         and tutorial_plume_on_slope (sensitive to truncation)
3895    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
3896      directly to drive seaice model (C-grid only)
3897    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
3898     - reintroduce computation of wind from stress,
3899     - compute tau (in exf_bulkformulae.F) from windstress averaged to
3900       mass points to avoid tau = 0
3901     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
3902    o rdmnc.m: make it work with "global" files created with gluemnc
3903    o rdmnc.m : some improvements in dealing with singleton dimension
3904      (tested on all testreport mnc output files).
3905    o genmake2: disable pkg/profiles if netcdf test fails.
3906    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
3907    o move call to cal_readparms up to make calendar parameters/variable available
3908      to all packages
3909    
3910    checkpoint58v_post (2007/02/08)
3911    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
3912      useDynP_inEos_Zc tested.
3913    o pkg/exf: changes to properly interpolate/mask/scale initial fields
3914    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
3915      and portions thereof.  See read_cs.txt for description and examples.
3916    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
3917      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
3918      following the great-circle arc between those 2 points.
3919    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
3920      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
3921    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
3922     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
3923     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
3924     - still needs work (not working with some options ; efficiency to improve)
3925       and serious testing.
3926     - use this scheme for temperature & salinity in 2 advection test exp.:
3927       advect_xy & advect_xz, respectively.
3928    
3929    checkpoint58u_post (2007/01/12)
3930    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
3931    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
3932    o testreport: add option "-skipdir" to skip some test.
3933    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
3934      momentum calculation.
3935    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
3936    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
3937      remove checkpoint.F and the_correction_step.F (no longer used);
3938      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
3939    o add option (linFSConserveTr) to correct for tracer source/sink due to
3940      Linear Free surface
3941    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
3942    o pkg/thsice: fix reading mnc-pickups
3943    
3944    checkpoint58t_post (2006/12/30)
3945    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
3946    o pkg/mdsio:
3947     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
3948       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
3949       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
3950     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
3951     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
3952       either MDS_READ_FIELD or MDS_WRITE_FIELD )
3953     - new S/R (to replace MDSWRITEMETA), which allows to write more
3954       informations (variable names, time ...) to meta files.
3955     - modify rdmds.m to give back the meta file content.
3956    o pkg/diagnostics: change vertical interpolation to be safer, and more
3957       flexible (define p-levels to interpolate to in data.diagnostics);
3958      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
3959       diagnostic pointer.
3960    o pkg/seaice: more cleaning up of seaice_growth, added many comments
3961    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
3962    o fix multi-category seaice:
3963     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
3964       SEAICE_MULTICATEGORY
3965     - fix short wave heat flux
3966    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
3967       and allow to use EVP solver. Change forward lab_sea: test both EVP
3968       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
3969    o Initial check-in of lab_sea adjoint
3970      (very similar to natl_box_adjoint/code_seaice)
3971      * used C-grid and EVP solver
3972      * used KPP, GM/Redi
3973      * uses inAdExact=.TRUE.
3974      * gradient checks fail for both ADM and TLM
3975        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
3976        f.d. gradients actually seem more problematic than ADM, TLM gradients;
3977        issue is related to forward mismatch between g77 an ifort
3978    o pkg/seaice: overhaul of thermodynamics
3979     - growth.F and groatb.F are replaced by new routine seaice_growth.F
3980     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
3981     - move a few global fields out of SEAICE.h into seaice_growth.F and
3982       make them 2D (FICE/QNETO/ ...)
3983     - remove FO (it is the same as QNETO)
3984     - introduce a few local fields to avoid modifying external fields such
3985       as atemp, etc.
3986    
3987    checkpoint58s_post (2006/12/11)
3988    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
3989      changed exf_set_gen.F so that
3990        genperiod=0 means input file is one time-constant field and
3991        genperiod=-12 means input file contains 12 monthly means
3992    o CG2D: use pre-computed solver main-diagonal (stored in common block);
3993      this affects truncation error ; generate new output file for exp. which
3994      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
3995        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
3996        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
3997        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
3998        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
3999        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
4000    o start implementation of deep-atmosphere and anelastic formulation
4001    o verification: remove 2nd copy of input files and use script "prepare_run"
4002      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
4003    o mom_common/vecinv/fluxform: fix a few initialisation isssues
4004    o profiles: fix for multithreaded case
4005    
4006    o diagnostics: rename few diags:
4007      s/'PRESSURE'/'RCENTER '/g
4008      s/'TICE    '/'oceFreez'/g
4009      s/'TAUX    '/'oceTAUX '/g
4010      s/'TAUY    '/'oceTAUY '/g
4011      s/'SWFLUX  '/'oceQsw  '/g
4012      s/DIFx/DFxE/g
4013      s/DIFy/DFyE/g
4014      and add few ocean-forcing diagnostics:
4015      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
4016    o modifications to pkg/seaice/growth.F and budget.F, which change results of
4017      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
4018      as actual snow thickness.  It now refers everywhere to effective snow
4019      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
4020    
4021    checkpoint58r_post (2006/11/17)
4022    o modifications to pkg/seaice/growth.F, which change results of
4023      lab_sea experiment: fixes pertain to melting snow over open water, to
4024      masking EVAP under sea ice, and to using the correct AREA variable for
4025      computations of EVAP, PRECIP, HSNOW, and GHEFF
4026    o add ability to read bathy, salt, and theta using MNC (off by def)
4027    o add flooding algorithm and advection of HSNOW for pkg/seaice;
4028      both are turned off by default and do no change any results
4029    o seaice advection with pkg/thsice: a step toward the use of non-linear
4030      advection scheme, but #ifdef or commented out for now (requires more EXCH).
4031    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
4032      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
4033      in natl_box (affects results @ truncation level: update output.txt)
4034    o multi-threading and IO:
4035      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
4036      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
4037        (needed to work with SingleCpuIO): tested in all verif. exp.
4038    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
4039      affects the results (but none of the verification test uses this scheme).
4040    o Adding some pkg/diagnostics capability to pkg/seaice
4041      (will certainly be subject to changes)
4042    o ctrl: adding new control variables:
4043      lwflux, lwdown, evap, snowprecip, apressure, runoff
4044    
4045    checkpoint58q_post (2006/10/20)
4046    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
4047      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
4048      high_res_cube configuration by 4% on Columbia.
4049    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
4050      add (in global_with_exf/code) a version of EXF_INTERP_READ without
4051      dynamical allocation (seems to work in multi-threaded).
4052    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
4053      single CPU io) so that TAF does not have to see EESUPPORT.h
4054    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
4055    
4056    checkpoint58p_post (2006/09/08)
4057    o obcs: stop if obcs is used with useCDscheme = .true.
4058    o shelfice:
4059     - fix a sign error so that no slip at shelfice interface works
4060     - remove stop for combination non-hydrostatic code and shelfice. That does
4061       not mean, that the results are correct, but at least they are numerically
4062       stable
4063    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
4064    o added adjoint exch routined for all exch*3d* routines
4065      and updated flow directives
4066    
4067    checkpoint58o_post (2006/08/28)
4068    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
4069      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
4070    o change controling S/R for writing pickup file (new S/R do_write_pickup)
4071      and clean-up reading/writing of pickup files.
4072    o fix local version of read/write pickup (NH part) in rotating_tank/code
4073    o simplify EXCH interface:
4074     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
4075     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
4076    o added the regrid package
4077    o shelfice:
4078     - add a simple boundary layer scheme to reduce noise
4079     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
4080    
4081    checkpoint58n_post (2006/08/14)
4082    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
4083       local variable (not in common block).
4084    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
4085      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
4086      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
4087        to work with SingleCpuIO.
4088    o add "_d 0" to real constant of pkg/cfc subroutines ;
4089       update exp. cfc_exemple & tutorial_cfc_offline output files.
4090    o multi-threading and IO:
4091      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
4092        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
4093      - barrier before and after reading.
4094      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
4095      - avoid using MDS_WRITELOCAL for LAND pkg output.
4096      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
4097        common-block variables ; Allows multi-threading with master-thread IO.
4098    o change default MAX_NO_THREADS from 32 to 4 ;
4099      and stop cleanly when MAX_NO_THREADS is too small.
4100    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
4101    
4102    checkpoint58m_post (2006/07/17)
4103    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
4104       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
4105    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
4106       keep global_ocean.90x40x15 (for AD testing) with former secondary test
4107       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
4108    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
4109        add MITgcm_tutorials (= code + all the tutorials)
4110    o ecco, option to compute cost for total ssh (mean+anom)
4111    o consistent with addition of ptracer and ssh in pkg/profiles
4112    o profiles: adding ptracer and ssh
4113    o testreport: change multi-test output-file name
4114      (from output.txt.{name} to output.{name}.txt)
4115    o profiles: now ok for mutli-tiles case
4116    o seaice: add 4 parameters for different advection schemes for area,
4117      (effective) seaice thickness, enthalphy, and snow height. Their default
4118      is the standard parameter SEAICEadvScheme
4119    o calc_gw:
4120     - add cosFacU in zonal viscous flux (harmonic.visc.).
4121     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
4122       of tutorial_plume_on_slope.
4123    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
4124    o calc_gw: true flux-form, account for horizontal grid spacing.
4125      update rotating_tank results, but not plume_on_slope (affected at
4126      truncation level, 11 digits).
4127    
4128    checkpoint58l_post (2006/07/12)
4129    o calc_gw:
4130     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
4131     - remove side-drag for now (need to fix it); update plume_on_slope results.
4132     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
4133    o commit code to make SST/SSS weights spatially variable
4134      (based on either variable in-situ or variable initial T/S weights)
4135    o pkg/ecco:
4136      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
4137        now based on horizontally varying weights wthetaLev, wsaltLev
4138      * cost_averagesflags now returns year indices in addition to day, month
4139      * sflux balance is performed on annual basis
4140        (sflxumm, sfluxmm2, bal_sfluxmm)
4141      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
4142        including separate counting and multipliers
4143    o pkg/rbcs
4144      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
4145    
4146    checkpoint58k_post (2006/07/06)
4147    o testreport:
4148     - always build in dir. "build" (if not there, mkdir build instead of building
4149       & running in input)
4150     - run in dir run (if it exists), in build otherwise.
4151     - call prepare_run (if input/prepare_run exists)
4152     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
4153    o pkg/exf modifications to interpolation and rotation routines for more
4154       reasonable treatment of North Pole singularity: for tracers North Pole
4155       value is set to northernmost zonal-mean value, for zonal velocity it is
4156       set to zero, and for meridional velocity it is set to northernmost value.
4157    o pkg/exf/exf_check_range.F
4158     - add tile index to diagnostics and move stop statement to the very
4159       end of the routine.
4160    o pkg/diagnostics: (diagnostics_main_init.F)
4161      define title of isomorphic variables according to the current config.
4162    o pkg/thsice with pkg/seaice dynamics:
4163    - fix domain of computation (interior only, required for exf) and do exchanges
4164    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
4165    o towards a standard way of dealing with multi-threading in MONITOR
4166      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
4167    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
4168       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
4169    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
4170    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
4171    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
4172       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
4173    o tracer advection:
4174     - clean-up and simplify calc_common_factors.F
4175     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
4176       advection subroutine (but still not used within DST advection S/R)
4177    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
4178    
4179    checkpoint58j_post (2006/06/15)
4180    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
4181      from file (collects calls previously in FORWARD_STEP)
4182    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
4183    o adjoint store dir. adjusted accordingly
4184    o genmake2
4185      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
4186    
4187    checkpoint58i_post (2006/06/14)
4188    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
4189      on wind stress (SEAICEstressFactor defaults to 1.)
4190    o Total number of Timers is finite (<=40): comment out 2 non-essential one
4191      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
4192    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
4193      on CS-grid: no longer loosing mass.
4194    o exf & curvilinear-grid: no longer modify longitude xC & xG.
4195    o pkg/ggl90: fix sloppy output and fix a bug
4196    o pkg/seaice: added SEAICEuseEVPpickup parameter
4197      - Set to false in order to start EVP solver with
4198        non-EVP pickup files when using SEAICEuseEVP
4199      - fix sign error in diffusion in seaice_calc_rhs
4200    
4201    checkpoint58h_post (2006/06/07)
4202    * Modifications for bottom topography control
4203      o replace hFacC by _hFacC at various places
4204      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
4205      o add non-self-adjoint cg2d_nsa
4206      o update autodiff support routines
4207      o re-initialise hfac after ctrl_depth_ini
4208      o works for 5x5 box, doesnt work for global_ocean.90x40x15
4209    * Adding verification for 5x5 box (4-layer) bottom topography control
4210    
4211    checkpoint58g_post (2006/06/07)
4212    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
4213       used for mean seasonal cycle, mean diurnal cycle); add an example
4214       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
4215    o pkg/ggl90:
4216      - add parameter (minimum surface kinetic energy)
4217      - fix bug (avoiding division by zero)
4218    o couple pkg/thsice to pkg/seaice:
4219      - modify advection in seaice to accomodate new scalar fields to be advected
4220      - only muliDimAdection scheme work with seaice/thsice
4221      - mapping of thsice-variables to seaice-variables, back and forth
4222      - does not break the verification experiments, but does not give the
4223        desired results either
4224    o pkg/seaice
4225      - make (default) second order advection a bit less confusing?
4226    
4227    checkpoint58f_post (2006/06/05)
4228    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
4229      to pkg/seaice):
4230      - new routines thsice_map_exf and thsice_get_exf provide the interface
4231      - add an additional formal parameter to thsice_solve4temp
4232    o pkg/exf:
4233      - add new fields wspeed, snowprecip (to be able to couple to thsice)
4234      - correct Stefan-Boltzmann constant
4235      - new parameter for longwave surface emittance
4236      - separate some stuff from exf_bulkformulae into new routines  
4237        exf_radiation, exf_wind
4238      - add new parameters and constants: longwave emissivity for ocean, ice
4239        and snow, evaporation parameters over ice
4240      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
4241        either wind from stress or stress from wind
4242    o pkg/thSIce:
4243    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
4244    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
4245       and THSICE_CALC_THICKN
4246    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
4247    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
4248      to make debugging easier.
4249    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
4250    o pkg/bulk_force:
4251      - clean-up comments and parameters ;
4252      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
4253    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
4254      generate new output for test-experiment: aim.5l_cs.thSI
4255    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
4256      testreport accordingly
4257    
4258    checkpoint58e_post (2006/05/17)
4259    o SEAICE_CGRID adjoint done
4260    o R_STAR adjoint implemented.
4261      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
4262      * need to sort out init. of h0facc, etc.
4263    o Make pkg/profile fully independent of ecco,cost, etc. stuff
4264      to be able to use it in pure forward.
4265    
4266    checkpoint58d_post (2006/04/21)
4267    o upgrade simple test-experiment to tutorial example:
4268     step.1: duplicate the experiment and (step.2) will remove the old copy.
4269      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
4270      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
4271      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
4272      tutorial_global_oce_biogeo    <- copy of dic_example
4273      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
4274      tutorial_plume_on_slope       <- copy of plume_on_slope
4275      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
4276      tutorial_global_oce_optim     <- empty for now (David ?)
4277      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
4278     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
4279    o correct a sign problem in cost_scat.F
4280    o obcs and ptracers: fix boundary conditions for advections schemes
4281      with larger stencil
4282    o thsice adjoint: start
4283    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
4284      completeness
4285    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
4286      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
4287    o ptracers adjoint:
4288      * avoid extensive recomputatations
4289      * fix missing re-init. of gptr (missed by TAF)
4290    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
4291      me to turn off the excessive output to STDOUT that this package produces
4292    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
4293      and add those terms in Vector-Invariant formulation.
4294    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
4295      if the control period (xx_hfluxperiod etc) is 0
4296    o in profiles pkg, clean routines and fix details
4297    o in ecco pkg, reading ssh data:
4298      fix problem in case the model does not start at iter0=0
4299    o fix mnc-pickup/restart for ptracers
4300    o new package prifiles:
4301      code to compute profile-based cost by Gael Forget
4302      (modifs in ecco, ctrl, autodiff)
4303    o Benign bug fix in initialization (spotted by M. Mazloff) of
4304      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
4305    
4306    checkpoint58c_post (2006/03/23)
4307    o adjoint: finish NLFS adjoint and provide reference output in
4308      verification/global_ocean.90x40x15/results_ad_nlfs
4309    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
4310      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
4311      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
4312      with SEAICE_CGRID defined.
4313    o move calendarDumps from "data" to "data.cal" and clean-up the code
4314      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
4315    o add useEXF & useCAL flags (for now, set in hard-coded way)
4316    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
4317      (were missing in NH mode, and wrong in quasihydrostatic mode).
4318      waiting for Chris updated version of calc_gw to add those CALLs.
4319    o fix bug in quasihydrostatic S/R ;
4320      add a test for this option: global_ocean.90x40x15.qshyd
4321    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
4322      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
4323    o add on/off flag useOffLine for package OFFLINE
4324    o seaice:
4325      - modify advection so that it works also on the C-grid
4326      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
4327        problem in multi-tile runs with C-grid
4328      - add flags for clipping ice velocities and/or masking solver forcing
4329      - fix drag (ocean on ice) formulation and a bug that caused noise in the
4330        C-grid solver
4331      - added a few comments to seaice_diffusion.F
4332      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
4333        are now exclusive)
4334      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
4335        required re-ordering the code a little:
4336       + make DAIRN global variable (defined in SEAICE)
4337       + move computation of the viscosities eta and zeta into a new separate
4338         routine (because I need to recompute them in seaice_ocean_stress.F)
4339    
4340    checkpoint58b_post (2006/03/13)
4341    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
4342      update output.txt of exp. aim.5l_cs.thSI
4343    o various mnc cleanups and improvements:
4344      + shrink lookup tables by factor of ~4
4345      + better error reporting when running out of lookup space
4346      + able to handle longer path/file names (up to 500 chars)
4347    o adjoint:
4348      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
4349      - TBD: "hidden" mom_vecinv recomp. in dynamics
4350    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
4351     (allow to differentiate between forcing components using new integer flags:
4352      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
4353     and add new flag to put Dissipation tendency out of Adams-Bashforth.
4354    o ecco
4355      - enable trend removal from SSH anomaly obs.
4356    o adjoint
4357      - a fix for PmEpR when #undef EXACT_CONSERV
4358      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
4359      - try to fix "hidden" recomp. in forward_step for NLFS
4360        (NLFS seems broken sometimes after I checked it in)
4361    o seaice:
4362     - add c-grid version of the dynamic solver:
4363       + three new routines that are the c-grid substitute lsr, dynsolver
4364         and ostres
4365       + put a few fields that were local to dynsolver into global common
4366         blocks, so that I can move the computation of stresses etc into
4367         seaice_lsr (saves coding but may break the adjoint).
4368     - replace more hardwired parameters by runtime parameters
4369     - add ice masks that mask the rhs of the implicit solvers where there
4370       is no ice (commented out in seaice_dynsolver, because i am not sure
4371       if this works properly), eventually this should replace the clipping
4372       of ice velocities in seaice_dynsolver to +/-40cm/s.
4373    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
4374      include it only where its needed
4375    o move balancing of fluxes before the call of external_forcing_surf
4376    o seaice:
4377      - correct units of turning angles (now they are really in degrees)
4378      - move computation of GWATX/Y out of main routine into dynsolver
4379      - initialize GWATX/Y in seaice_init
4380    o Apply mask on Fresh-Water flux (needed for SSH forcing).
4381      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
4382    o seaice: add runtime flags for turning angles (default to zero)
4383    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
4384      and trend from exf forcing and ctrl control adjustments
4385    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
4386      (since checkpoint57x_post)
4387    o change the default rotation period to 86164.s = the Earth rotation
4388    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
4389      and based on a reference stratification. Tested within hs94.cs-32x32x5.
4390    o seaice advection: add code for choosing between the default (2nd order
4391      central differences) and multiDim advection schemes provided by
4392      pkg/generic_advdiff
4393    o seaice:
4394      - removed all references to SEAICE_GRID.h fields from
4395        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
4396        (cubed-sphere configuration will change a little)
4397      - grid computations in seaice_init are obsolete now.
4398      - cleaned up code a little so that is easier to read (hopefully).
4399      - added new (better?) discretizations of default advection and diffusion
4400        (turn on with SEAICEuseFluxForm)
4401      - replace 1 in 3d global fields by kSurface in growth.F
4402      
4403    checkpoint58a_post (2006/02/13)
4404    o seaice:
4405      - bug fix in advect.F
4406    o shelfice:
4407      - separate shelfice load anomaly from pload (breaks with time
4408        dependent forcing), => introduce constant field shelficeLoadAnomaly.
4409        Its default is 0., but it may be computed more cleverly from (unknown)
4410        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
4411        done offline. A good approximation of the pressure load anomaly is
4412        necessary to avoid large initial adjustment processes underneath
4413        deep-reaching shelfice.
4414      - small fix in ISOMIP shelfice_thermodynamics
4415      - add more sophisticated thermodynamics of Hellmer (1989), this is
4416        now the default
4417      - give a few constants more intuitive names
4418    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
4419      if bulk formulae are used in long integration (especially EmPmR). Turn
4420      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
4421      if balancePrintMean, the imbalance that is substracted is printed to
4422      STDOUT.
4423    o fix bug (typo) in obcs_apply_eta.F
4424    o add a new package shelfice which enables us to model the circulation
4425      underneath shelf-ice with draughts of hundreds of meters.
4426     - works
4427     - to do: + include improved thermodynamics
4428              + check whether kSurfC (from model/inc/SURFACE.h) can be used
4429                instead of new field kTopC
4430              + can we use topoFile, Ro_surf and existing code in ini_depth.F
4431                instead of new field R_shelfIce and new code in ini_depth.F
4432                and ini_mask_etc.F?
4433              + adjust vertical mixing schemes?
4434    o seaice pkg:
4435     - add a cpp-flag to include a simple formula for a salinity dependent
4436       freezing point of sea water at the surface
4437     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
4438       meridional stresses are now different (and hopefully correct)
4439    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
4440       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
4441       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
4442    o pkg/diagnostics: add options and parameters for regional-statistics
4443       diagnostics ; define regions by reading a region-mask from a file
4444       (might add other options later)
4445    o pkg/bulk_force:
4446     - add option and parameters to use AIM surface-flux formulae.
4447     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
4448       others forcing fields (defined in PARM05, parameter file "data") are loaded
4449       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
4450     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
4451     - use the right EXCH call for uwind,vwind (to work on CS-grid).
4452     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
4453       and parameters (note: calcWindStress replaces .NOT.readwindstress).
4454     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
4455    
4456    checkpoint58 (2006/01/12)
4457    o add "--embed-source" option to genmake2 which, when the supporting
4458      tools can be compiled (as determined by genmake2) will turn on the
4459      embed_files package which then embeds the entire MITgcm source code
4460      (*.[fFhc] + Makefile) used for the build within the executable
4461      - requested by CNH but off by default
4462      - adds a paltry <9MB to the mitgcmuv executable in most cases
4463      - only writes the output when useEMBEDSRC in eedata is true
4464    o clean up 3-dim. relaxation codes:
4465      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
4466      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
4467      * Thanks to Tom Haine for testing!
4468    
4469    checkpoint57z_post (2005/12/31)
4470    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
4471      affects output (@ truncation level) of exp. plume_on_slope ; updated.
4472    o fix the pickup behavior for obcs in combination with ptracers
4473    o fix a bug in ptracers_external_fields_load
4474    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
4475      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
4476    o transfered surface NH pressure to eta field (if exactConserv).
4477    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
4478         and update lab_sea output.txt file.
4479    o completing 3-dim. relaxation code: additional term
4480         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
4481      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
4482      * At compile time, in "EXF_OPTIONS.h" set
4483          #define  ALLOW_CLIMTEMP_RELAXATION
4484          #define  ALLOW_CLIMSALT_RELAXATION
4485      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
4486          tauThetaClimRelax3Dim = 15552000.0,
4487          tauSaltClimRelax3Dim  = 15552000.0,
4488      * 3 cases:
4489          1) Use a constant-in-time 3-dim. field
4490          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
4491          3) Real-time relax. to time-evolving prescribed field
4492    o Adding Laplacian-type smoothness constraint on
4493      initial and boundary (forcing) controls (ic, bc)
4494      * enable at compile-time via
4495        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
4496      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
4497      * Absolute scale somewhat unclear so far
4498      * no area weighting was included since no other cost term does so far
4499    
4500    checkpoint57y_post (2005/12/08)
4501    First step for a NLFS adjoint
4502    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
4503    o new init. routines for calc_r_star, calc_surf_dr
4504    o still need to deal with ini_masks_etc
4505    o testreport seemed happy
4506    checkpoint57y_pre (2005/12/08)
4507    
4508    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
4509    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
4510    o add new offset feature to offline pkg (plus minor cleanup)
4511    o cfc fixes for final year of integration
4512    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
4513      be in GCHEM_OPTIONS).
4514    
4515    checkpoint57x_post (2005/12/04)
4516    o fix testreport Pb in multiple test experiment.
4517    o cleanup our namelist syntax in verification:
4518      - make it more F95 standards compliant (some work still needed)
4519      - allows the vast majority of our tests to work with gfortran
4520    o Non-Hydrostatic:
4521     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
4522     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
4523    o Allow to apply AB on T,S rather than on AB(gT,gS):
4524     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
4525     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
4526       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
4527     - need a "clever" read_pickup to restart from the other AB formulation
4528    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
4529    o remove some unused variables (reduces number of compiler warnings)
4530    o adjoint
4531      * Disable useVariableViscosity for adjoint for time being
4532        (there are a number of extensive recomputations)
4533      * Initialize certain variables needed for adjoint
4534    
4535    checkpoint57w_post (2005/11/03)
4536    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
4537                 fix the singleCpuIO RS version of MDSWRITEFIELD
4538       and add a WARNING if using globalFiles=T with multi-processors.
4539    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
4540      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
4541    o tracer advection scheme:
4542      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
4543       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
4544       was not very convenient).
4545      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
4546       (further tests needed for the implicit DST & Flux-Limiter schemes).
4547    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
4548      and sRef for convenience, handy, when you want to initialize
4549      ptracers in a large domain with a constant non-zero value. Also,
4550      untangle ptracers_init.F a little.
4551    
4552    checkpoint57v_post (2005/10/13)
4553    o change dome exp. to use variable viscosity in side-drag terms.
4554    o remove all the files from the cfc_offline test since they are now
4555      incorporated into tutorial_cfc_offline which has been producing
4556      identical results for a few days of testing
4557    o add new parameter: sideDragFactor to enable half-slip-side BC
4558      and change side-drag S/R to use viscosity from mom_calc_visc
4559      (can switch back by setting sideDragFactor=0.); affects results at
4560      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
4561       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
4562    o vorticity & strain are now computed without masking, to account for
4563      no-slip-side BC in variable viscosity calculation ; mask is applied
4564      anyway later on, before computing advection/coriolis terms.
4565    o modify exp4 to test new obcs support for reading from external files
4566      and for passive tracers
4567    o fix behavior of ptracers_monitor when monitor output is written to a
4568      netcdf-file; still not independent of monitor.F (writes in the same
4569      file).
4570    o change default value of tRef (put a uniform, meaningful value for ocean
4571      & atmos) and initialize sRef (was missing, as Martin mentioned).
4572    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
4573      to be proportional to enstrophy dissipation length.  Thus,
4574       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
4575      This is now consistent with Smagorinsky and with the manual.
4576    
4577    checkpoint57u_post
4578    o OBCS and PTRACERS: add open boundary support for passive tracers
4579      - either use homogenous (pseudo) v.Neumann conditions or prescribe
4580        OB-values from file; this is not different from the way theta and salinity
4581        are treated
4582      - however, Orlanski-radiation conditions are not supported, and the model
4583        will stop if you use pTracers and Orlanski at the same time.
4584      - beefed up the rountine obcs_external_fields_load: now only those open
4585        boundary values are overwritten with values from files for which there
4586        are really files, otherwise the OB-fields remain untouched. This makes
4587        it possible to use different OBs at different ends of the domain (as
4588        with EXF)
4589    o reduce number of exch calls in shap_filt (s2).
4590    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
4591      truncation level) 4/5 MLAdjust test results (11&12 digits match).
4592    
4593    checkpoint57t_post (2005/10/03)
4594    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
4595    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
4596      same truncation, independent of the face number: affects affects several
4597      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
4598    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
4599      note that biharmonic viscosity + no-slip was not tested in any experiment.
4600    o fix bug in non-linear free-surf side-drag ; generate new output for
4601      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
4602    o make mnc honor the writeBinaryPrec flag for most kinds of output
4603    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
4604    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
4605      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
4606    o add brackets in multi-terms sum to get same truncation, independent of
4607      the face number (manage to get exactly same value of gU,gV at the cs-edge)
4608      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
4609    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
4610      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
4611      a maximum grid-scale Reynolds number.  Also, changes all length calculations
4612      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
4613      Suggested values of viscosity parameters found in mom_calc_visc.
4614      Many new viscosity diagnostics available.
4615    
4616    checkpoint57s_post (2005/09/20)
4617    o Add clearing-house for viscosity calculations, mom_calc_visc and
4618      correct numerous bugs in LeithD and Smagorinsky discretizations.  
4619      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
4620      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
4621      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
4622      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
4623      The Strain-Tension form is now called with useStrainTensonVisc=.true.
4624      ViscAhStrain and viscAhTension are now retired.
4625    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
4626    o In response to JMC's bug report, genmake2 now ignores any soft-links
4627      that it finds in the *current* directory when searching for files.
4628      Soft-links found in any other source directories will still work as
4629      they did before.
4630    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
4631      a C routine to unlimit the stack size
4632    o mnc-ify pkg/aim snapshot vars
4633    o mnc-ify pkg/land as requested by Daniel
4634    o various changes to mnc including:
4635      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
4636      - output can now be grouped so that all files within a group
4637          change the ITER portion of their names in lock-step together
4638      - can now read ("global") PER-FACE (in addition to PER-TILE) files
4639          and works with both EXCH1 and EXCH2 (but needs more testing)
4640      - writing works for all verification test cases w/ g77 on Linux
4641    
4642    checkpoint57r_post (2005/09/07)
4643    o make MNC variable initialization happen earlier
4644    o add diagnostics for (almost) each term of the momentum Eq.
4645    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
4646    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
4647    o remove MINIMAL_TAVE_OUTPUT option ;
4648      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
4649    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
4650      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
4651    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
4652    o add time-dependent SST, SSS control
4653    o cost terms in ecco/ modularized (new cost_generic.F)
4654    o cost_averages routines are modularized (new cost_averagesgeneric.F)
4655    o new infrastructure for seaice model vs. obs misfits in seaice/
4656      * driver from the_main_loop.F is seaice_cost_driver.F
4657      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
4658      * gradient check in Exp. 6a of natl_box_adjoint/
4659    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
4660      (see README file)
4661    
4662    checkpoint57q_post (2005/08/19)
4663    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
4664    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
4665      - bug was reported by Jean-Michel and Ian Fenty
4666    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
4667      update exp. cpl_aim+ocn output.
4668    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
4669      Needed for high-res. runs with large global files
4670      to be able to limit tapelev size
4671    o Changed some tests for adjoint:
4672      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
4673      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
4674      * global_ocean.90x40x15/ back to default 3-level checkpointing
4675    o Modifications to enable scripted COMMON to MODULE conversion
4676      * verification/OpenAD/code/ has necessary scripts and description;
4677      * converts, compiles and runs successfully;
4678    
4679    checkpoint57p_post (2005/08/01)
4680    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
4681    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
4682      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
4683    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
4684    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
4685      (was already the case for dissipation with mom_vecinv,
4686       and also the case for grad.PhiHyd when staggered-timeStep)
4687      This will allow to put dissipation out-off the AB time-stepping.
4688     Unfortunately, affects truncation error. Update output of exp. that "fails"
4689      (cg2d matching number) and leave the others for later: front_relax(10),
4690      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
4691      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
4692    
4693    checkpoint57o_post (2005/07/30)
4694    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
4695      (2) its ready to be documented during the 20050801 DocFest
4696    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
4697      for ideal_2D_oce and lab_sea on linux_ia32_g77
4698    o set to #undef CTRL_SET_OLD_MAXCVARS_30
4699      in global1x1_tot/code_seaice_adj to access indices 32, 33
4700      (worth another tag)
4701    
4702    checkpoint57n_post (2005/07/29)
4703    o adding precip control xx_precip 32
4704    o adding swflux control xx_swflux 33
4705    o Replacing 10 forcing penalty cost routines by 1 generic.
4706    o Implementing partitioning in time-mean and variable adjustment
4707      for atmos. state.
4708    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
4709    o in natl_box_adjoint:
4710      * updated exp 1 to 10
4711        (but does not have time-mean vs. variable split results yet)
4712    o updated global1x1/*_seaice_adj/
4713      to incorporate latest changes
4714    o enable useSingleCpuIO for mdsio vector routines
4715      (applies in particular to tapelev I/O)
4716    o removed inefficient K-loop in all active_file*control*.F
4717    
4718    checkpoint57m_post (2005/07/28)
4719    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
4720      and advect_cs (use EXCH-2 and standard cs-32 grid files).
4721    o pkg/exch2: filling of face-corner halo regions is optional
4722      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
4723    
4724    checkpoint57l_post (2005/07/14)
4725     tag before updating tutorials (pre-release-2)
4726    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
4727       for output and interpolation of input fields onto model grid)
4728    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
4729       Affects results of exp. rotating_tank ; update output.txt.
4730    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
4731          and taking the square quantity and/or using a fraction-weight field.
4732    o fix aim_diagnostics_init.F mate numbers.
4733    o add mnc output capability to diagnostics/diagstat and update
4734      our cvsignore files for the ACSII output generated
4735    
4736    checkpoint57k_post (2005/07/02)
4737    o lab_sea now uses diagnostics package and provides a suite of
4738      new EXF diagnostics output.
4739    
4740    checkpoint57j_post (2005/06/30)
4741    o exf
4742      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
4743        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
4744        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
4745      * extended diagnostics output
4746        - now includes all EXF variables
4747        - hs, hl moved to common block
4748        - separate S/R for diagnostics, called after ctrl vector is added
4749        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
4750        - EXFqnet contains true Qnet (i.e. includes qsw)
4751      * updated verif. lab_sea, global_with_exf
4752      * Rearranging hflux (exf_mapfields -> exf_getforcing)
4753        to ensure that diagnostics sees a true EXFqnet
4754    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
4755    o diagnostics pkg: change pointers so that 1 diagnostic can be used
4756      several times with different frequencies.
4757    o mnc-ify the thsice package as requested by Daniel Enderton
4758      - the monitor--MNC output needs work
4759      - many attributes need to be added (most are currently blank)
4760    o mnc-ify theaim_v23 package as requested by Daniel Enderton
4761      - many attributes need to be added (most are currently blank)
4762    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)

4765      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
4766         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
4767    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
4768     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
4769    
4770    checkpoint57i_post (2005/06/19)
4771    o Diagnostics package was changed: diagnostic allocation is now deactivated
4772      by setting an empty file name in the namelist (used to be by setting 0 frequency)

4774      add 1rst Order upwind vertical Shear.
4775    o add a quick fix for A/B checkpointing in OFFLINE mode
4776    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
4777      end-run around the C/Fortran linking horror in eesup/src/timers.F
4778    o added pkg/runclock: allows user to terminate run based on wall clock
4779    o added non-hydrostatic scaling parameter: nh_am2
4780    o pkg/my82: futile attempt to make results compiler-independent by adding
4781      some "_d 0", etc. no effect.
4782    o for mnc output, fill the 'T' coordinate var with myTime and create a
4783      separate 'iter' variable for iteration count
4784    o pkg/diagnostics:
4785      add new capability: output of Global/Regional & per-level statistics ;
4786      tested against monitor output (including land & thSIce) on various exp.
4787    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
4788    
4789    checkpoint57h_done (2005/05/19)
4790      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
4791      data.diagnostics, data.gchem, data.ptracers) is done.
4792    
4793    o pkg/diagnostics: prepare for Global/Regional statistics.
4794      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
4795    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
4796      and rename it: DIFFERENT_MULTIPLE
4797    
4798    checkpoint57h_post (2005/05/14)
4799    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
4800    o pkg/diagnostics: change output frequency, now in seconds (instead
4801      of Nb of iterations). This requires to change data.diagnostics.
4802    checkpoint57h_pre (2005/05/12)
4803    
4804    o in mnc, let the user create the output dir if both mnc_outdir_date
4805      and mnc_outdir_num are false
4806    o add fflags() to pkg/diagnostics which allows one to specify, on a
4807      per-file basis, the file precision [default behavior is unchanged]
4808    o added diagnostics to pkg/kpp, including computation of mixed layer
4809      depth based on a temperature/density criterion
4810    o updated verification/natl_box to test the new pkg/kpp diagnostics
4811    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
4812    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
4813    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
4814      not mnc -- this mistake was found by JMC and is now corrected
4815    
4816    checkpoint57g_post (2005/04/15)
4817    o add Adams-Bashforth 3rd Order time stepping:
4818      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
4819      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
4820    checkpoint57g_pre (2005/04/15)
4821    
4822    o make lambda[Theta,Salt]ClimRelax spatially varying
4823      (default remains spatially uniform constant based on tau)
4824    o added new control variables
4825      * init. uVel, vVel, etanN
4826      * lambda[Theta,Salt]ClimRelax
4827    o separate masks used for ctrl_pack/unpack 'from write_grid' output
4828      (suggested by G. Forget)
4829    
4830    checkpoint57f_post (2005/04/06)
4831    o add parameter "baseTime" = model base time = time at iteration zero
4832      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
4833      account for baseTime shift
4834    o move Coriolis arrays from PARAMS.h to GRID.h
4835    checkpoint57f_pre (2005/04/06)
4836    
4837    o mnc-ifying the seaice package
4838    o introduced an alternative length scale calculation for use in the limiting
4839      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
4840    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
4841    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
4842      as well as grad(vort3).  Made it compatible with both approximate form
4843      for the cubed sphere and full form of these gradients.  Added flag
4844      useFullLeith to select between approximate and full form.  
4845    o add "d0" in getcon.F to reduce differences between compilers/platforms
4846      update output.txt of exp. fizhi-gridalt-hs
4847    o change port_rand funtion to allow to set the seed.
4848    o fix obscure MNC bug involving conversion between reals and integers
4849      - it caused no problems with certain (eg. gcc, ifc) compilers but the
4850        new version is now more standards-compliant
4851    o adjoint-related modifications
4852      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
4853      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
4854      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
4855    
4856    checkpoint57e_post (2005/02/28)

4860    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
4861      update output.txt of exp. fizhi-gridalt-hs
4862    o add more "Z" dimensions and associated coordinate vars to MNC
4863    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
4864    o parameter calendarDumps: when set, approximate months (30-31 days) and years
4865      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
4866      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
4867      months and years.  Requires pkg/cal.
4868    o diagnostics: add pickup functionality
4869      - off by default for backwards compatibility
4870      - current version only uses MDSIO -- MNC will be added
4871    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
4872    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
4873    
4874    checkpoint57d_post (2005/02/11)
4875    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
4876    o modify verification/ideal_2D_oce so that it tests the creation of mnc
4877      output from the diagnostics package
4878    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
4879    o make genmake2 more portable by using ".$FS" instead of ".f" for more
4880      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
4881    o add coordinate variables to the MNC output from the diagnostics package
4882    o change MNC-flags default value: true when useMNC=TRUE
4883    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
4884      the ability (off by default) to read the grid information using MNC
4885    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
4886    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
4887    o do snap-shot diagnostics at the middle of the time-interval (instead of
4888      at the end).
4889    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
4890      new test for AIM with thSIce + slab-ocean
4891    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
4892    o move state variable diagnostics to the beginning of the time step ;
4893      (note: still needs some work specially for snap-shot diagnostics)
4894      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
4895    
4896    checkpoint57c_post (2005/01/27)
4897    o Change testing option (-ieee) to get closer agreement between g77 & ifort
4898    o generate new output.txt files on faulks with g77 & the new -ieee option
4899    checkpoint57c_pre (2005/01/27)
4900    
4901    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
4902      update output.txt of exp. global_ocean.90x40x15
4903    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
4904      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
4905    o add saltFlux(+File) forcing capability with periodicExternalForcing
4906    o allow to use pkg diagnostics for GM-Redi & ThSIce output
4907    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
4908    o improvements for the MNC output from DIAGNOSTICS:
4909      - correct handling of the unlimitied dimension
4910      - all dims now have associated coordinate variables
4911      - variables located at U, V, and Corner ("Z") points are now written
4912        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
4913        *all* data points are output
4914    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
4915    o added pkg/seaice/seaice_monitor.F
4916    o mdsio_readfield.F can now read files visible only to master MPI process.
4917    o pkg/seaice: some test code for ice-modified ocean stress
4918    o exf_getffields interpolation defaults to bilinear for all scalar forcing
4919      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
4920      spurious negative numbers for precipitation and humidity.  Will cause
4921      some small numerical differences for integrations using pkg/exf/exf_interp.F.
4922    o pkg/ctrl/
4923      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
4924        May be enabled via doPackDiag
4925      *  introduce z-scaling of
4926         + gradient (doZscalePack) and
4927         + control (doZscaleUnpack)
4928    o pkg/mdsio/
4929      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
4930      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
4931    
4932    checkpoint57b_post (2004/12/20)
4933    o simplify options in diagnostics_fill arguments (remove weird combinations)
4934    o fix MNC coordinate variables so that they now contain per-face index
4935      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
4936      general, EXCH2 grids are only aligned to a "local" coordinate system
4937    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
4938    o Implement instantaneous output within pkg diagnostics:
4939      setting a negative frequency in data.diagnostics produces
4940     "snap-shot" output (as opposed to time-average if freq > 0)
4941    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
4942      NOTE: change ptracer diagnostics name: use 2 characters to work with
4943            more than 9 tracers. Add also diagnostics of advect & diffus flux.
4944    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
4945      becomes the coordinate variable for the 'T' dimension
4946    o add CF-style coordinate variables to MNC
4947      - just a first cut:  numbers are meaningless on the cubesphere and
4948        missing along the T axis but otherwise it works!
4949    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
4950    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
4951    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
4952      this is based directly on what the model compute, so that the content of
4953      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
4954    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
4955    o clean up build options files for SunOS, in particular
4956      - remove -traditional from xmakedepend
4957      - change -xarch=v9 to -xarch=native for f77
4958      - restore use of make (not gmake)
4959      - add CC=gcc if using g77
4960    o changes per discussion of AM, JMC, & EH3 today:
4961      - move redundant "grid" variables out of "state" -- in preparation of
4962        creating proper CF-style coordinate variables and in recognition
4963        that any/all grid variables can be easily copied (eg. w/NCO) from
4964        the grid files into any of the other NetCDF files
4965      - *always* output grid variables with MDSIO (this will eventually be
4966        changed)
4967      - output MNC grid file if useMNC is true
4968    o every instance of _END_MASTER() has been found and replaced with
4969      _END_MASTER( myThid ) in order to satisfy certain picky Sun
4970      preprocessors
4971    o re-arrange diagnostics pkg initialisation:
4972     - allow each package to extend the available diagnostics list
4973     - add some checking and fix small problems (multi-threaded, ...)
4974     - new S/R diagnostics_fill (replace fill_diagnostics):
4975       look through the short list of active diag. (instead of the long list)
4976       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
