5      ==============================      ==============================
6    
7    o verification/tutorial_tracer_adjsens/
8      - add extra sub-verification which uses "SOM" advection scheme
9        (2nd Order-Moment Advection Scheme, Prather Limiter) with
10        #define GAD_ALLOW_TS_SOM_ADV in GAD_OPTIONS.h
11        and in data:
12        multiDimAdvection=.TRUE.,
13        tempAdvScheme=81,
14        saltAdvScheme=81,
15    
16    checkpoint63o (2012/06/29)
17    o vertical mixing schemes:
18      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
19      - replace computation of density (in Function STATE1, opps_calc.F) by a call
20        to S/R FIND_RHO_SCALAR
21      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
22        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
23        affects output (vermix.ggl90) at truncation level.
24    o testreport:
25      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
26        (nSx,nSy) for the number of threads (from eedata.mth)
27    o model/src:
28      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
29        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
30    o verification/tutorial_tracer_adjsens/
31      - compile with ALLOW_CG2D_NSA
32      - run with nonlinFreeSurf=3
33      - update reference output_adm.txt
34    o tools/genmake2:
35      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
36        refine usePROFILES switching off (only when NetCDF is not available).
37    o verification (atmospheric set-up):
38      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
39    o pkg/profiles : refine profiles and files handling.
40    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
41    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
42      - changes to use model/src/the_main_loop.F rather than the ecco version
43        in ecco type adjoint runs.
44    o model/src:
45      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
46      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
47      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
48    o model/src:
49      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
50        update output of test experiment bottom_ctrl_5x5.
51    o pkg/generic_advdiff:
52      - implement vertical bi-harmonic diffusion (for now, only for T & S and
53        only explicitly).
54    o verification/bottom_ctrl_5x5/
55      update reference output (results changed quite some time ago,
56      not sure when; but new reference results look ok in terms of grdchk)
57    o verification/1D_ocean_ice_column/
58      For verification purposes, the exact adjoint rather than an approx.
59      should be used (e.g., to comare against F.D. or TLM).
60      removed autodiff_inadmode*_ad.F routines in code_ad/
61      Update results/ accordingly.
62    o pkg/cal:
63      - change cal_getdate.F so that output date is function of input time only
64        (less ambiguous, not mixed up with input iteration number).
65      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
66    o pkg/diagnostics:
67      - implement calendarDumps also for stats-diags
68      - implement calendarDumps also for snap-shot output (negative freq)
69      - for now, ignores calendarDumps if non-zero phase-lag.
70    
71    checkpoint63n (2012/06/04)
72    o model/src:
73      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
74        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
75      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
76        similar to calc_r_star.F); update results of experiment internal_wave and
77        tutorial_global_oce_in_p (affected @ truncation level).
78    o pkg/shelfice:
79      - add parameterisation of advective-diffusive flux into the ice shelf
80        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
81      - simply eps3/3a computation
82    o eesupp:
83     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
84       between tiles, just fill-in edges assuming locally periodic subdomain) and
85       add corresponding exchange subroutines (EXCH0);
86     - new CG-solver version (_EX0) for disconnected-tiles special case.
87    o model/src (CG-solvers):
88     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
89       (similar final residual output and max-Iter number as with standard version);
90     - allows to store and use lowest-residual solution (standard & _SR versions);
91     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
92     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
93    o eesup/src:
94     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
95       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
96    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
97    
98    checkpoint63m (2012/04/27)
99    o pkg/shelfice:
100     - account for partical cells in surface level below ice-shelf for hydrostatic
101       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
102    o ad test experiments:
103     - update and rename to "ad_optfile.local" local AD-optfile specific to a
104       particular adjoint verification experiment (in verification/*/code_ad/)
105    o pkg/seaice & pkg/exf:
106     - Part two of ECCO-CLIVAR code merges.
107       Completes merge of seaice area relax. code.
108       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
109       to be set in EXF_OPTIONS.h since this pkg controls its I/O
110       (and avoids second CPP option in SEAICE_OPTIONS.h)
111     - change default value of costIceStart & costIceEnd to a valid date.
112     - add snowPrecip to HSNOW in seaice_growth
113    o pkg/ptracers:
114     - move ptracers summary and setup check into separated S/R ; add a check for
115       valid PTRACERS_Iter0 value (error+stop or just warning).
116    o pkg/cal (+ pkg/ecco):
117     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
118       as input; and for AD, unless both are not differentiable (e.g., k index)).
119    o model/src:
120     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
121       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
122       temporary set to usingZCoords value (to be changed to F when using shelfice).
123     - hydrostatic pressure: implement partial cell near the surface also for
124       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
125       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
126    o pkg/ctrl/ctrl_init.F:
127     - add a formal parameter to s/r ctrl_init_rec to print
128       xx_$(ctrl_valiable)_file for easier debugging
129     - move call of cal_* routines into the if-block where they are really
130       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
131       to specify a startdate
132    o pkg/seaice:
133     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
134       global_ocean.cs32x15/code versions).
135     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
136       verification experiment global_ocean.cs32x15.seaice and update results.
137    o pkg/exf:
138     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
139       (according to useExfYearlyFields).
140    o pkg/cal:
141     - move calendar setting & summary (previously in cal_readparams.F) into new
142       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
143       length of the simulation is set (after SET_PARMS call); This is an attempt
144       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
145     - For safety: keep a record of pkg/cal parameter settings status
146               to allow to STOP if one pkg/cal S/R is called too early.
147     - add a stop in all basic pkg/cal subroutines if called before setting is done.
148     - modify cal_getdate.F: stop when nothing was returned;
149       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
150       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
151    
152    checkpoint63l (2012/04/04)
153    o pkg/bbl:
154      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
155        update global_with_exf output.yearly.txt file.
156    o pkg/cal:
157      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
158      - remove 2 unsused and very short (1 line only) functions ;
159      - remove unsused subroutines from AD-Diff list.
160    o model/src:
161      - start to implement clean wait to stop in initialization S/R (config_check.F,
162         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
163    o folowing PRINT_MESSAGE changes:
164      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
165    o pkg/bbl:
166      - modification so it can work with z*
167      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
168      - global_with_exf/input.yearly verification; changes output.yearly.txt
169    o eesupp/src:
170      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
171        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
172      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
173        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
174      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
175      - when using MPI, always set usingMPI=T ; set default accordingly and stop
176        if not consistent.
177      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
178        argument is zero (in case called within single-thread section).
179    o pkg/fizhi:
180        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
181        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
182    o pkg/exch2:
183      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
184        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
185      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
186        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
187        with bad ones coming from a not-yet-updated halo.
188        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
189    o pkg/frazil:
190        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
191        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
192    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
193    o verification/lab_sea
194      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
195      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
196      * nTimeSteps 3 -> 4
197      * changed reference output accordingly
198    o pkg/ctrl:
199      * fix ctrl_get_gen for xx_sst, xx_sss
200    o pkg/fizhi:
201      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
202        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
203      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
204        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
205        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
206    o pkg/gmredi:
207      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
208    o pkg/fizhi:
209      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
210        (old)aces open64 tuv test.
211    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
212    o pkg/mom_vecinv:
213      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
214        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
215        with non-lin free-surf).
216    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
217      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
218      some compilers (gfortran 4.6.0 on MacOS)
219    o momentum:
220      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
221        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
222        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
223    
224    checkpoint63k (2012/03/17)
225    o model/src:
226       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
227         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
228       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
229         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
230    o model/src: solve_*diagonal.F
231       - replace division with multiplication by inverse (similar to original version)
232         update output of AD exp. global_ocean.90x40x15.
233       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
234         to enable the use of the vectorized & differentiable solve_tridiagonal.F
235       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
236         vertical advection (to get solve_tridiagonal tested in AD mode).
237    o pkg/seaice: ECCO-CLIVAR merge:
238      1. seaice AREA relaxation
239         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
240         * runtime flag: SEAICE_tauAreaObsRelax
241      2. modified global mean cost imbalance code: CPP option
242          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
243    o another iteration on solve_*diagonal.F
244       Make choices independent of AUTODIFF
245       Default will be the adjoinable vectorized version.
246       Alternative choices are:
247       * non-adjoinable original version with low memory footprint:
248         #define SOLVE_DIAGONAL_LOWMEMORY
249       * still adjoinable but does not vectorize (k as inner-most loop):
250         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
251    o testreport
252     - add option to use a home made wrapper around "make"
253     - remove MITGCM_IEEE env. variable (no longer active)
254    o pkg/shelfice
255     - improve computation of friction velocity for velocity dependent
256       exchange coefficients: include velocities into SHELFICEBoundaryLayer
257       block to average velocities vertically
258     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
259    o Modify diagonal solvers, now three versions (upon request):
260      #ifndef SOLVE_DIAGONAL_AUTODIFF
261        1. default version (dating back a while ago)
262      #else /* def SOLVE_DIAGONAL_AUTODIFF */
263      # ifdef SOLVE_DIAGONAL_KINNER
264        2. adjoinable version with k-innermost loop (G. Forget)
265      # else
266        3. adjoinable vectorized version of 2.
267      # endif
268      #endif /* SOLVE_DIAGONAL_AUTODIFF */
269      All flags are currently set within routines, but could/should be moved to CPP-options.
270      Array bounds for 1. are as before, for 2.,3. cover the entire domain
271      (could be changed for 1. too).
272    o verification/lab_sea (fwd):
273      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
274        use 7 categories (except hb87), new solve4temp params (except salt_plume),
275        constant salinity (=4) or variable salinity (salt_plume) done through
276        SItracer.
277    o pkg/seaice:
278      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
279      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
280         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
281        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
282        SEAICE_freeze got retired) but already better than previously with
283        SEAICE_freeze=123456.7 deg.C;
284      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
285        (safer multi-threaded setting); always set SEAICEuseEVP;
286      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
287        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
288        stop if multiple specifications for the same coeff; make sure default
289        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
290    o pkg/obcs:
291      - allow to switch to upwind 1rst order advection scheme for the advective
292        flux computation at the open-boundary; disabled for adjoint built.
293    o pkg/ptracers:
294      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
295      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
296      - add parameter to decide when to start a tracer; use internal flag to
297        know which tracer to step-forward; switch this internal flag at the top
298        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
299        for adjoint built.
300    o pkg/seaice:
301      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
302      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
303      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
304    o pkg/ecco:
305      - fix writing of output file DiagnosCost_ClimSalt/Theta
306        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
307    o pkg/seaice:
308      - add missing initialisation of COR_ICE array in dynsolver.F
309      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
310        compiled either way, and is tested in all exps (multidim was only tested
311        in lab_sea ad before).
312      - cosmetic change to prepare for future addition of ITD. no change to results.
313        no defaults change.
314      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
315      - by lack of adequate verification experiments, I further used custom versions
316        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
317        should be correct.
318      - avoid recomputations in ad.
319    o array initialisation in adjoint mode:
320      1) pkg/mom_common/mom_calc_ke.F:
321        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
322        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
323        part this initialisation is gone, resulting in Floating Point Exception
324        (caught by open64 compiler with debug option).
325      2) model/src/convective_weights.F
326        set output convectCount over the full array range (instead of doing
327        an update): this fix a similar issue when called within recomputation (adjoint)
328        which could by-pass the initialisation (normally done in the caller S/R).
329    o pkg/seaice:
330      - final version of turbulent flux params, as agreed at MIT ice meet:
331           SEAICE_mcPheePiston (default is ~ 0.000875)
332           SEAICE_mcPheeTaper (default is 0.)
333           SEAICE_frazilFrac (defualt is 1.)
334           SEAICE_mcPheeStepFunc (default is false)
335      - changes results at trunction error level
336      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
337    o added pkg/frazil:
338      - see frazil_description.tex for details
339      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
340    o pkg/shelfice/shelfice_thermodynamics.F
341      - fix exponents for velocity dependent exchange coefficients: change
342        from 2/3(=0) to 0.66666666666666667
343      - move computation of velocity dependent exchange coefficients into
344        separate loop, so that it applies to both thermodynamics
345      - move some divisions by constants out of loops
346    
347    checkpoint63j (2012/02/16)
348    o pkg/seaice:
349      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
350      - SItracer:  added run time params, and allow coupling to ocn salinity.
351    o pkg/seaice: remove (almost) all divisions by constants within loops
352      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
353      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
354      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
355      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
356    o pkg/seaice :
357      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
358        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
359      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
360      - add permanent SItflux diag that corresponds to TFLUX but includes
361        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
362      - allow activation/testing of a fix for suspected missing term in
363        ocn-ice heat budget (to be confirmed). To test this, you want to
364        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
365        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
366      - no change in results, fwd or ad.
367    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
368      - switch to variable freezing point.
369           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
370      - bug fix : the sublimation term that was missing is now activated.
371           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
372      - bug fix : flooding sign term for SIsal0.NE.0.
373           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
374    o pkg/seaice:
375      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
376        is now the default, and the old default constant freezing point is recovered
377        with SEAICE_tempFrz0    = -1.96,
378             SEAICE_dTempFrz_dS = 0.,
379      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
380      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
381      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
382        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
383      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
384        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
385      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
386        seaice_growth r149 for legacy branch (no results change).
387      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
388        from I. Fenty).
389      - results did not change except for global_ocean.cs32x15, mostly due to the
390        switch to variable freezing point (see above item for detail).
391    o pkg/thsice:
392      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
393        seawater freezing in thsice_calc_thickn (not used).
394    o pkg/seaice: turbulent flux term specification via run time params.
395      - replace CPP switches with run time switches to facilitate testing
396      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
397                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
398      - added runtime parameter : SEAICEturbFluxFormula
399      - move Mcphee constants to SEAICE_PARAMS.h
400      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
401                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
402                 remove seaice_summary call (moved to seaice_init_fixed)
403      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
404        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
405      - seaice_summary.F : add missing report of read turbulent flux term set up
406                           and SITRACER.
407      - seaice_check.F : check range; inform and stop if retired CPPs are used
408                         (incl. SEAICE_AGE).
409      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
410             CPP switch, same computation as before for the different options.
411      - change results at the truncation level.
412    o pkg/seaice:
413      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
414        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
415        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
416      - update verification/*/input*/data.seaice:
417        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
418        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
419        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
420        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
421    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
422      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
423        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
424        difference in results only due to machine truncation.
425      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
426        MaykutPolySatVap; keep MIN_LWDOWN.
427      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
428      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
429        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
430    o pkg/salt_plume:
431      - isolate saltPlumeFlux array exch into a specific S/R called from
432        do_oceanic_phys.F
433      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
434    o verification:
435      - move untested set-up to MITgcm_contrib/verification_other.
436    o pkg/seaice:
437      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
438    o pkg/seaice:
439      - seaice_solve4temp.F (keeping results unchanged):
440        * add 2 future run-time params to select which saturation vapor pressure
441          formula is used and how post-iteration fluxes are set.
442          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
443        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
444          the linearized expression to stay consistent with tsurf finding.
445      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
446        can be < 0.
447    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
448      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
449        conductive heat flux F_c , and add it explicitly when updating tsurf as
450        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
451        so that now F_ia has a consistent meaning through the entire routine.
452        This causes differences at truncation level: update output of fwd exp.
453        global_ocean.cs32x15.seaice.
454    o pkg/seaice:
455      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
456        of arrays, sign/direction of fluxes; no effect on results.
457      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
458        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
459        note: this should have been done before changing celsius2K default.
460      - to keep results unchanged, add back old value of celsius2K in verification
461        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
462      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
463        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
464        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
465        freezing temp is consistent with value in seaice_growth.F ; this causes
466        differences at machine truncation level: update lab_sea AD output (3/4).
467    o pkg/seaice:
468      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
469        and climsst/sss even when using seaice (to prevent calculation that might
470        use SST on land); does not affect any verification exp.
471      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
472        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
473    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
474      over land (non-legacy code)
475    o vectorize salt_plume package:
476      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
477      - this code computes plumebk everywhere (also over land), thus requires
478        code to avoid divisions by zero and catch the case of kLev=Nr.
479      - efficiency of salt_plume_frac is still sub-optimal
480    o tools (genmake2):
481      - fix makefile NAME specification (option: -makefile NAME) by adding
482        "-f $MAKEFILE" in few places where it was missing including makedepend
483        command (contribution from Paul).
484    
485    checkpoint63i (2012/01/24)
486    o model/src:
487      - add factorized versions of some EOS code to find_rho.F,
488        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
489    o model/src:
490      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
491      - change default celsius2K from 273.16 to 273.15
492      - to keep results unchanged, add back old value of celsius2K in verification
493        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
494         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
495    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
496      to make TAF generate vectorizable code
497    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
498       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
499       have flags that do this more efficiently.
500    o pkg/diagnostics/diagstats_calc.F
501      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
502    o pkg/obcs (with exch2):
503      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
504        and remove code (in obcs_readparms.F) which was based on EXCH of indices
505        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
506    o pkg/exf and seaice exp:
507      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
508        so that switching off area & heff advection flags does not affect results.
509      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
510      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
511        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
512        results of verification experiments: 1D_ocean_ice_column(fwd),
513        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
514        and offline_exf_seaice (all 4).
515    o pkg/seaice:
516      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
517        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
518      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
519        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
520        not multi-dim advection;
521      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
522        SHORTWAVE_HEATING #undef.
523    o optim: make Makefile more robust (?)
524    o pkg/obcs:
525      * fix treatment of obcs_read_pickup for TAF
526    o pkg/shelfice:
527      * add missing initialisation of num_shifwflx
528      * new adjoint verification exp. for isomip
529      * change Prandtl and Schmidt numbers from generic formulations
530        (in terms of model diffus. and visc.) to separate runtime
531        parameters, with Holland and Jenkins (1999) default values.
532    o pkg/exf (interpolation):
533      - extended input field (2 rows) near the N & S poles:
534        * fill in with the symetric value (when even Nb of data in longitude)
535        * add average value at the poles only for scalar quantities ; for vector
536          component interpolation, skip the averaging and keep duplicated values,
537          unless the 2 components have same location (uvInterp=T) in which case
538          interpolate the 2 components together using S/R EXF_INTERP_UV.
539      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
540        together: this allows to account properly for local orientation when
541        averaging at N & S pole.
542      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
543        exf-interpolation near N & S poles. Undef by default.
544      - add debug check/print on 1rst iter if debugLevel >=2.
545    o pkg/exf:
546      - change masking flags definition (no longer "parameter"), put them in
547        common block and set them in S/R EXF_INIT_FIXED.
548      - change recognized masking flag from s,u,v to c,w,s since the mask
549        to use (maskC,W,S) depends on position on model grid and has little to
550        do with scalar/vector difference; fix masking if using P-coordinates.
551      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
552        and update results of exp. global_with_exf (x2).
553      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
554    o pkg/obcs
555      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
556    o pkg/exf (interpolation):
557      - assume periodicity in X only if input field cover full longitude range.
558      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
559        and should vectorise).
560      - fix input lat of the 2 added row (in case we provide N.pole data).
561    
562    checkpoint63h (2011/12/30)
563    o pkg/seaice:
564      - change declaration of UVM from _RL to _RS in order to get B-grid
565        uIce,vIce monitor when _RS = real*4
566    o pkg/offline:
567      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
568      - compute vertical velocity if not read from file (switch on exactConserv
569        & staggerTimeStep);
570      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
571    o verification:
572      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
573        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
574        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
575      - update output of exp. global_ocean.cs32x15.viscA4 after changing
576        grid-file angles (used here for coriolis-3d);
577      - remove (or gzip) few files not needed to run fizhi-cs experiments.
578    o pkg/exf (vector interpolation):
579      - rotate vector component toward local grid-axis orientation using grid-angles
580        (stored in GRID.h) instead of locally computed rotation angle; keep old code
581        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
582    o pkg/seaice:
583      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
584        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
585    o pkg/PKG_OPTIONS.h files:
586      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
587        outside of the #ifdef ALLOW_THISPKG / #endif block.
588      - update verification/*/code/PKG_OPTIONS.h files.
589    o add a verification experiment (offline_exf_seaice/input.seaice) that test
590      the B-grid LSOR solver
591    o pkg/seaice: sort out emissivity and long wave radiation step 2:
592      - add emissivity for snow and ice as new run-time parameters
593        (unfortunately) that default to the corresponding exf values; this
594        changes results in most verification experiments so that for backward
595        compatibility these parameter have to be set explicitly to inconsistent
596        values (ugly);
597      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
598        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
599        until we agree how to handle this bug properly
600    o pkg/exf (interpolation):
601      - add a set of run-time param ({inputfield}_interpMethod), one for
602        each interpolated input field, to select the interpolation method
603        with a value of zero switching off the interpolation;
604      - print interpolation parameters to standard output;
605      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
606        (to use instead runoff_interpMethod=0 in data.exf).
607      - simplify default setting of interpolation parameters (for all fields,
608        set position to match model grid cell-center position, leading to trivial
609        interpolation in case of regular Lat-Lon grid) and fix for the case of
610        non-uniform delY.
611    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
612       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
613       this factor is absolutely required, because the lw exitance (= out-going
614       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
615       where the reflectivity rho = 1-emissivity for conservation reasons. Once
616       this is established, we can remove the CPP-Flag (if we want to).
617    o pkg/seaice:
618      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
619        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
620      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
621        what the name implies (and not emissivity*BoltzmannConstant), this means
622        the old default value of 5.5e-8 now means
623        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
624        S/R exf_readparms
625      - FV-discretization of the B-grid LSOR solver, turn on with
626        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
627        of the calling routine dynsolver, so that B and C-grid code look a
628        little more alike.
629      - fix index bugs in ostres.F (B-grid code)
630    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
631    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
632      default for SEAICE_emissivity, if useEXF; requires setting a wrong
633      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
634      backward compatiblity
635    o model/src: use sigmaR in calc_ivdc
636    
637    checkpoint63g (2011/12/16)
638    o pkg/seaice/seaice_growth.F:
639      fix heat conservation of the coupled ocean-seaice system.
640      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
641      solid vs liquid water treatment is resolved via QNET.
642    o pkg/seaice/seaice_growth.F:
643      add missing term for sublimation in saltFlux, which was breaking conservation.
644    o pkg/seaice/seaice_model.F:
645      Remove this patholigical case treatment in evolution branch,
646      where it is un-necessary and breaks conservation.
647      Update global_ocean.cs32x15/results accordingly for
648      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
649    o model/src:
650      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
651      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
652    o pkg/obcs:
653      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
654      tendency for temperature and salinity that is then applied to update
655      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
656      horizontal advection and diffusion contributions on the boundary (in
657      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
658      removing the mask in S/R timestep_tracer. The advantage of this approach is
659      that the updated tracer values include contributions from the surface
660      forcing and vertical diffusion.
661      This modification changes exp4.stevens because of vertical diffusion.
662    o model/src:
663      change non-curvilinear grid setting to also work with exch2 + blank tiles:
664      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
665        face dimensions.
666      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
667        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
668        and INI_SPHERICAL_POLAR_GRID.
669      change test-experiment global_ocean.90x40x15:
670      - split the domain in many more tiles (9x4 tiles of 10x10 each);
671      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
672      - update results of both test (std & dwnslp).
673    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
674       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
675    o model/src:
676      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
677        and fix initialisation when using sigma-coords.
678    o model/src:
679     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
680       to their current value at the beginning of forward_step.F": add a new run-time
681       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
682     - set doResetHFactors=T in the following test exp:
683        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
684        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
685        and tutorial_global_oce_in_p (nonLinFS in p)
686    o pkg/ecco
687      - added IES cost term
688    o verification/advect_xz
689      - scale down the depth by 1/100 (from 200 km to just 2.km)
690      - add secondary test using divergent flow, r-star and implicit vertical advection.
691      - add note (check_conserve_TS.txt) and matlab script to check global
692        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
693    o pkg/rbcs:
694      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
695    o pkg/obcs (Stevens BCs):
696      - fix various problems in the phase speed computations of the Stevens
697        boundary conditions:
698        - sign error for western and southern boundaries,
699        - time tendencies were underestimated by factor of dTracerLev and some just
700          zero (for multidim advection schemes) -> now estimate time tendencies
701          from difference between previous (n) time level and the one before (n-1);
702          this requires storing a field per tracer per boundary, also in the pickup
703          files.
704        - replace deltaTmom in cflMer/Zon computation with dTracerLev
705        - set default phase velocity to cflMer/Zon
706      - update verification experiment exp4.stevens
707    o pkg/generic_advdiff (implicit_r):
708      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
709        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
710      - fix implicit vertical diffusion or advection with NonLin FreeSurf
711        (was using current recip_hFacC instead of future recip_hFacC): set future
712        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
713        solver S/R ;
714      - fill diagnostics of vertical advective fluxes (computed from tendency)
715        when using implicit vert. advection;
716      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
717         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
718         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
719         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
720    o pkg/diagnostics:
721      - add diags for T & S tendency which goes through Adams-Bashforth.
722    
723    checkpoint63f (2011/11/30)
724    o pkg/obcs/obcs_calc_stevens.F:
725      - join some loops to reduce number of if-statements
726      - fix a bug in code for northern and southern boundaries.
727    o pkg/seaice/seaice_init_varia.F
728      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
729        caused zero ice-velocities for the B-grid code
730    o pkg/seaice/seaice_init_fixed.F
731      - fix a bug in the initialisation of the second metric terms
732        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
733      - this affects all seaice configurations with useCurviLinearGrid = .true.
734        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
735        = .true. (default)
736      - the only verification experiment affected is global_ocean.cs32x15:
737        icedyn, seaice, and seaice_dynmix (AD)
738    o pkg/thsice/thsice_diagnostics_state.F
739      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
740        not contain garbage that can lead to surprises in diagstats_calc.F
741    o model/src:
742      - move bi,bj loops inside INTEGR_CONTINUITY ;
743      - call INTEGR_CONTINUITY directly from forward_step.F
744        (previously called from momentum_correction_step.F)
745      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
746        forward_step.F and pkg/ecco/the_main_loop.F
747    o model/src/do_oceanic_phys.F:
748      - reset addMass to zero only if useICEFRONT ;
749      - separated k-loop for rhoInSitu calculation ;
750      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
751        and at constant T,S (= WdRHOdP);
752      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
753        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
754        transport of locally-referenced potential density);
755        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
756    o gluemnc:
757      - replace ncrcat with ncks when adding variables to *.glob.nc
758      - change the way variables without record dimensions are handled so that
759        files that have variables with and without record variables can be glued:
760        add a record dimension with a new unique name to be able to differentiate
761        between variable with and without a-prior record dimensions. Remove
762        this record dimension before adding the variable to the *.glob.nc file.
763        This procedure automatically works also for grid.*.nc files that do not
764        have any record dimension.
765    o verification/cpl_aim+ocn:
766      - generate new reference output on baudelaire (gfortran, mpich2) (previously
767        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
768    o pkg/obcs/obcs_calc_stevens.F:
769      - add code for northern and southern boundaries.
770      - reorder some loops to save some operations and so that drFBar can be scalar
771    o model/src:
772      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
773        truncation) and add diagnostics for Adams-Bashforth tendency increment.
774      - update test-exp. AD output:
775        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
776      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
777        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
778        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
779        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
780        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
781        tutorial_plume_on_slope.
782    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
783      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
784      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
785      does not even come with an F77 compiler anymore, this should not be
786      a limitation
787    
788    checkpoint63e (2011/11/06)
789    o pkg/seaice adjoint of LSR:
790      - substantially rework STORE dirs.
791      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
792        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
793        and only perform SOLV_MAX_FIXED adjoint iters.
794        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
795        always goes to same record, meaning that the last forward field will be
796        the one used in the adjoint - an approximation.
797      - now produces non-zero LSR-related gradients, and acceptable gradients for
798        An's zonal (x-z) test case (to be checked in)
799      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
800        (but these are screwed up by the thermodynamics in the first place);
801        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
802        output_adm.txt also reflects changes to seaice_lsr
803      - global_ocean.cs32x15:
804        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
805          (output_adm.seaice.txt was updated)
806        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
807          (output_adm.seaice_dynmix.txt)
808    o test-exp. exp4+stevens:
809      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
810    o pkg/seaice (lsr solver):
811      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
812        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
813      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
814      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
815        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
816      - compute (with new S/R) and print initial (+ free-driff sol. if available)
817        and final residual of linearised system.
818    o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
819      (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
820    o pkg/obcs: Stevens BCs (still only for east and west)
821      - fix Stevens BCs by using intermediate velocities of previous
822        time step as "baroclinic" contribution rather velocity of one grid cell
823        inside the boundaries; more consistent but makes the entire treatment
824        more complicated, requires new pickup files and two new S/Rs:
825        obcs_copy_uv_n and obcs_save_uv_n
826        keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
827        (undefined by default)
828      - silently move computation of some grid factors into separate loops to
829        save some recomputations
830      - add a hack for non-linear free surface
831      - add a verification experiment to exp4 that tests this code
832    o make gluemnc/xplodemnc work with (moron) non-GNU shell tools
833    
834    checkpoint63d (2011/10/25)
835    o pkg/obcs + seaice-dynamics:
836      - new implementation calls OBCS_APPLY_UVICE (in seaice_dynsolver.F) before
837        solving for uIce,vIce and prevent SEAICE_LSR or SEAICE_EVP to modify OB
838        values (consistent with an implicit method).
839      - add option OBCS_UVICE_OLD (in OBCS_OPTIONS.h, defined by default) to
840        return to older implementation (same results as before); note that none of
841        the "experimental" OBCS_SEAICE options are implemented in the new version.
842      - switch test exp. seaice_obcs to use new version (update output).
843    o pkg/seaice:
844      - add few stop (B-grid & CS-exch, B-grid & obcs, AUTODIFF & SEAICE_maskRHS)
845      - add parenthesis in Water-Ice drag calculations (evp & lsr);
846      - in seaice_lsr.F, simplify and fix AA3 setting in case sNx or sNy=1;
847        and fix case SEAICE_waterDrag=0 (but unstable if no or little seaice)
848      - update output of test exp lab_sea that uses evp or lsr (fwd+ad)
849        and global_ocean.cs32x15 (icedyn & seaice fwd+ad).
850    o pkg/layers:
851      - Include potential density as new coordinate (Thanks to David Munday)
852    o pkg/dic:
853      - Remove subroutine CALC_PCO2_APPROX_CO3 from carbon_chem.F and add
854        carbonate computation/output to CALC_PCO2_APPROX
855    o pkg/generic_advdiff
856      - make TAF generate code that vectorizes:
857        gad_dst3fl_adv_*.F, gad_u3c4_impl_r.F
858    o model/src:
859      - improve vectorization also for adjoint code of
860        solve_tridiagonal and solve_pentadiagonal. As this requires up to
861        5 new 3D-fields, this code is only turned on for the combination of
862        ALLOW_AUTODIFF_TAMC and TARGET_NEC_SX. Also remove error message
863        for singular matrix check (only for TARGET_NEC_SX).
864      - remove hard-wiring of CPP-flag ALLOW_SOLVERS_KLOOPINSIDE to
865        ALLOW_AUTODIFF. This flag now needs to be set outside of
866        solve_tri/pentadiagonal.F
867    o pkg/exf:
868      - fix previous modif in exf_readparms.F (revision 1.66: treatment of
869        optional namelist EXF_NML_OBCS).
870      - add many debug-print (to trace down where pkg/cal error msg comes from)
871    o pkg/mom_vecinv/mom_vi_hdissip.F
872      - rearrange loops so that vectorization is improved and in particular
873        the adjoint routine vectorizes. The code is a little longer now, but I
874        think easier to read.
875        Note: CPP-flag MOM_VI_ORIGINAL_VISCA4 is not tested.
876    o pkg/seaice:
877      - allow to specify initial seaice velocity from files (uIceFile,vIceFile)
878    o pkg/exch2:
879      - alternative code (without tile x tile matrix) for cumulated (global) sum;
880        used as default; keep using matrix version in adjustment.cs-32x32x1.
881    o tools/build_options:
882      - after merging some MPI and/or multi-threads specific optfiles so that
883        the modified default optfile support both built (using genmake2 -mpi
884        for the MPI built, using genmake2 -omp for OpenMP built),
885        move now obsolete optfiles to tools/build_options/unsupported/
886       (add copy of email sent to support list in doc/optfiles_changes.txt)
887    
888    checkpoint63c (2011/09/28)
889    o pkg/ebm:
890      - fix ebm_zonalmean.F for several procs in Ydir (nPy > 1); update output of
891        test exp. global_ocean_ebm (affects machine truncation, 12 digits for cg2d)
892    o pkg/seaice (SItracer pickup)
893    * Simple code for pickup of SItracer fields (#define ALLOW_SITRACER)
894      To be done:
895      - thorough testing of missing fields in S/R seaice_read_pickup
896      - thorough matching between generic tracers and specific fields used
897        (e.g. volume-weighted age, area-weighted age, salinity, ...)
898    o pkg/grdchk:
899      - all procs calculate and print finite-difference gradient (for testreport)
900      - change description output used by testreport;
901      - AD testing: also compare and report Finite-difference gradient;
902        => update all output_adm*.txt
903    o test exp. global_ocean_ebm:
904      - switch back useRealFreshWaterFlux (no problem anymore with run-off);
905        and turn on exactConserve; update (fwd) output.
906    o pkg/seaice (LSR):
907      - print to STDOUT number of solver iterations at SEAICE_monFreq interval.
908      - modify solver to deal cleanly with u/v switch at face edges (CS-grid):
909        * identical results with non-CS topology (but save up to half of EXCH calls)
910        * no much changes in cs-32 verification tests since no ice at face edges
911         (differences due to convergence criteria, since nb of iterations changed)
912        * expect some differences on lat-lon-cap grid.
913        update FWD results of global_ocean.cs32x15 test exp. (icedyn & seaice)
914    o pkg/exch2:
915      - add new CPP option to disable Cumul-Sum matrix (to save storage when using
916        many tiles); until alternative coding is added, just add a stop.
917    o pkg/kpp:
918      - move ptracer/salt correction to KPP diffusivity from calc_3d_diffusivity.F
919        to S/R KPP_CALC_DIFF_PTR (+ add tracer-index to argument list).
920    o optfiles:
921      - merged few MPI specific (*+mpi*) and multi-threads specific (*+mth) optfiles
922        into corresponding standard one, which now support different build:
923        (when using "genmake2 -mpi" for MPI built, "genmake2 -omp" for OpenMP built)
924      - add "darwin_amd64_gfortran" optfile (initially from Constantinos, tested by Gael)
925    o pkg/obcs (seaice):
926      - add missing EXCH for uIce,vIce after applying OBCS;
927      - remove S/R EXF_SWAPFFIELDS_X/Y , disable S/R EXF_SET_OBCS_X/Y by adding
928        argument = number of levels to S/R EXF_SWAPFFIELDS_XZ/YZ and S/R
929        EXF_SET_OBCS_XZ/YZ ; update obcs_exf_load.F;
930      - fix EXF_SET_OBCS_XZ/YZ for multi-threaded (assuming loaded arrays are shared)
931      - verification exp. seaice_obcs: split domain in 2 tiles ; add SIZE.h_mpi
932        and eedata.mth for MPI and mutlti-threaded testing.
933    o pkg/flt:
934      - make FLT EXCH working with multi-threads (and MPI + multi-threads);
935      - use buffer for floats IO (trajectories & profiles); size set in FLT_SIZE.h;
936      - fix pickup and trajectories + profiles output with multi-threads;
937      - add parameter to select group of fields to write along trajectory and
938        profile (default unchanged);
939      - only call PORT_RAND* function when flt_noise <> 0;
940      - add multi-threaded test for verification exp. flt_example.
941    o eesupp/src:
942      - fix S/R ALL_PROC_DIE for MPI+multi-threads.
943      - USE_OMP_THREADING: check that number of threads (from eedata) matches
944        actual number (from env.var. setting).
945    o pkg/ebm:
946      - fix multi-threading in ebm_area_t.F ; clean-up EBM.h header file.
947      - add multi-threaded test for verification exp. global_ocean_ebm
948    
949    checkpoint63b (2011/08/29)
950    o pkg/ebm:
951      - fix sign of runoff;
952      - update directly forcing fields (Qnet,EmPmR) to use standard
953        external_forcing_surf.F (remove ebm_forcing_surf.F);
954      - avoid loading forcing fields a 2nd time (1rst time from ini_forcing.F);
955      - set either tauThetaClimRelax (in data) or tauThetaZonRelax (in data.ebm)
956        and apply relaxation towards corresponding SST field (2-D map or ZonAver).
957      - update global_ocean_ebm parameters file data and update output (fwd+ad).
958    o verification/matrix_example:
959      - split domain in 8 tiles (2x4); add SIZE.h_mpi and eedata.mth for
960        MPI and mutlti-threaded testing.
961    o pkg/matrix:
962      - change name of S/R MATRIX_INIT to S/R MATRIX_INIT_VARIA ;
963      - fix for multi-tiles (add bi,bj indices to exp/impMatrixCounter);
964      - fix for multi-threaded (remove DATA statement);
965      - use standard DIFFERENT_MULTIPLE function;
966      - add MATRIX_OPTIONS.h
967    o verification/matrix_example:
968       To allow to split the domain in several tiles, change the domain size
969        from 31x31 to 32x32 by adding 1 row (on Southern side) + 1 column (on
970        Western side) of land points.
971    o (*_)write_pickup:
972      - fix few bugs in mypackage_read/write_pickup.F
973      - in MDS_WR_METAFILES calls, replace "myTime" by a local copy into
974        array of length 1 (was caught by compiler syntax-check).
975    o pkg/diagnostics (velocity potential solver):
976      - fix initialisation of main diagonal matrix (for overlap values)
977    o tools/build_options:
978      - towards single optfile for MPI and non-MPI built: merge few +mpi optfile
979        into previously non MPI one (linux_am64 pgf77,open64,pathf90,ifort11)
980      - linux_amd64_gfortran: merge +mpi_generic version into standard optfile:
981        * move IEEE flags to DEVEL section; take IEEE flags from +mpi_generic ;
982        * FAST case: for now, keep -O3 with ini_masks_etc.F in NOOPTFILES list;
983        and use "-devel" testreport option for standard testing on baudelaire.
984    o pkg/grdchk:
985      - Assume that all gradient-check position are within the same tile
986        corresponding to global indices (iGloTile,jGloTile) and that
987        positions (i,j indices or nbeg) are local to this tile;
988      - set tile local-indices and proc. number according to tile global-indices;
989      - remove grdchkwhichproc from namelist (retired param);
990      - send adjoint gradient to all procs so that all procs print it to STDOUT;
991      - switch on MPI test for global_ocean.90x40x15 AD test experiment.
992    o adding package bbl (Bottom Boundary Layer)
993      description in MITgcm/pkg/bbl/bbl_description.tex
994      example/test experiment in MITgcm_contrib/bbl
995    o adjoint verifications
996      - changed 5 experiments to multi-tiles
997        * global_ocean.90x40x15
998        * obcs_ctrl
999        * offline_exf_seaice
1000        * tutorial_dic_adjoffline
1001        * tutorial_tracer_adjsens
1002        changed reference output for those that crossed tile boundaries
1003        (changed choices of gradient check positions)
1004      - with same tiling, switch on MPI test for the last 4 (add SIZE.h_mpi)
1005      - temporary bug fix in grdchk_loc.F for obcs
1006    o genmake2 & testreport
1007      - add target "obj" (just for OBJFILES files) to Makefile;
1008      - add option to specify FEXTRAFLAGS on command line.
1009    o pkg/mypackage:
1010      - remove bi,bj arguments from argument list of S/R MYPACKAGE_CALC_RHS
1011    
1012    checkpoint63a (2011/08/02)
1013    o pkg/diagnostics (velocity potential):
1014      - fix velocity-potential calculation when using OBCS: balance net inflow
1015        at each level (new S/R OBCS_DIAG_BALANCE).
1016      - fix some of the problems with OBCS in stream-function calculation.
1017    o pkg/exf/exf_readparms.F
1018      - make treatment of optional namelists (EXF_NML_04, EXF_NML_SGRUNOFF,
1019        EXF_NML_OBCS) more consistent, so that you need not have these lists
1020        in data.exf when they are not used.
1021    o optim/optim_readdata.F:
1022      - add some output about obcs variables that might help debugging
1023      - add a check about nvarlength
1024    o pkg/ctrl: once again, fix computation of endrec in s/r ctrl_init_rec
1025    o pkg/diagnostics (velocity potential):
1026      - fix mask for OBCS (still problems in stream-function with OBCS);
1027      - add specific parameter (default = main code CG2D params) for solver;
1028      - in case of poor convergence, use solution corresponding to lowest residual.
1029    o pkg/seaice/seaice_growth.F: small changes that permit vectorizable
1030      adjoint code. In general statements like tmpscal=fld(i,j) are problematic
1031      and should be avoided where possible.
1032    o model/src (rStar):
1033      - include r* effect on reference-state (PhiRef) in totPhiHyd
1034        (so that it's really the potential anomaly at the cell center);
1035        affect solution only if z* with full pressure in EOS.
1036      - test-exp global_ocean.90x40x15: reduce viscA4 (was not stable) and
1037        update output (because of z* in totPhiHyd and viscA4 changes);
1038      - keep the previous diagnostics as "PHIHYDcR" (closer to potential anomaly
1039        @ constant r) until interpolation at constant r is implemented.
1040    o pkg/diagnostics
1041      - fix RCENTER diagnostics in case cell center is not at interface middle
1042    o add code for TEOS-10 (www.teos-10.org, McDougall et al. 2011). Use
1043      this eos with eosType = 'TEOS10', in data (PARM01). This eos implies
1044      that THETA and SALT are "conservative temperature" and "absolute
1045      salinity"
1046    o pkg/ctrl
1047      - fix computation of endrec in s/r ctrl_init_rec
1048      - ctrl_pack/unpack_*: remove unused variables and some obsolete code
1049    o pkg/seaice/seaice_growth.F
1050      - fix recomputation with FENTY_AREA_EXPANSION_CONTRACTION code,
1051        remove then obsolete STORE directives
1052      - fix STORE directives for tice and tices, so that only the
1053        appropriate part of the fields are stored (and not the entire
1054        field); update global_ocean.cs32x15.seaice AD output.
1055      - cosmetic changes: adjust CPP flags and indentation for better
1056        legibilty
1057    o pkg/autodiff: add mnc-output of adBottomDragFld (code contributed by
1058      Chris Wilson)
1059    o pkg/gmredi:
1060       Add Sub-Meso Eddies parameterisation from Baylor (for now, disabled with TAF),
1061       and test it in verification exp. "front_relax.bvp" (update output.bvp.txt)
1062    
1063    checkpoint63  (2011/07/11)
1064    o pkg/exch2:
1065     - rename+move: nTiles in W2_EXCH2_PARAMS.h --> exch2_nTiles in W2_EXCH2_TOPOLOGY.h
1066     - exch2 version of Cumul-Sum routine: S/R W2_SET_MAP_CUMSUM set up the
1067       (2*nTiles)x(nTiles) Cumul-Sum matrix and Master Proc collects all tiles X,Y
1068       increments, calculates Cumul-Sum @ tile origin and sends results to each tile.
1069    o pkg/diagnostics:
1070     - deal with pairs of post-processed diags which are computed together; in
1071       particular, re-order list of diags within 1 file to save 2nd computation.
1072     - add S/R to compute velocity stream-function (called after velocity-potential
1073       calculation) from divergence free transport -> new diagnostics "PsiVEL".
1074     - add parameter to select grid-point location where PsiVEL == 0.
1075    o eesupp/src:
1076       new S/R to calculate cumulated sum on tiled array, corner grid-cell location
1077       (specific S/R needed with exch2 topology - for now, just print an error msg)
1078    o pkg/shelfice
1079     - Implement friction velocity-dependent transfer coefficients following
1080       Holland and Jenkins, JPO, 1999
1081       Original code by M. Losch with small modifs.
1082       Enable with CPP option SHI_ALLOW_GAMMAFRICT
1083       and runtime flag SHELFICEuseGammaFrict
1084    o verification lab_sea & global_ocean.cs32x15:
1085     - use tools/xmakedepend (instead of cyrus_makedepend, in genmake_local):
1086       does not miss some dependencies (but is slower) and also works with many files
1087       (default makedepend limitation for AD built).
1088     - use cyrus_makedepend in adjustment.128x64x1 (so that it still tested).
1089    o pkg/diagnostics:
1090     - add run-time parameter "useMissingValue" (def=False) to fill land-point
1091        (i.e., where mask=0) with MissingValue ; used only in MNC output file.
1092       This replaces CPP-option DIAGNOSTICS_MISSING_VALUE.
1093     - Extend the use of "missing_value" setting from data.diagnostics for the case
1094       of counter-diagnostics (where fraction-weight is zero). This applies both to
1095       MNC and MDS output files.
1096    o pkg/seaice/seaice_growth.F:
1097      - add 'a priori' cap of latent heat flux based on actual mass considerations
1098        when SEAICE_ADD_SUBLIMATION_TO_FWBUDGET is used in conjunction with the
1099        non-legacy seaice_solve4temp.
1100      - add diagnostic of the residual sublimation freshwater flux (the freshwater
1101        flux taken from the ocean if the total actual latent heat fluxes exceed
1102        the maximum)
1103      - remove the CPP switch around the *_FWbySublim unit change and move diagnostic
1104       fill for SIatmQnt, SIfwSubl, SIatmFW to the end of seaice_growth.F.
1105      - add diagnostic of the actual sublimation freshwater flux (that is 0. ifndef
1106       SEAICE_ADD_SUBLIMATION_TO_FWBUDGET) and of the latent heat flux (evap+sublim).
1107      - bug fix : frWtrAtm needs a_FWbySublim ifdef SEAICE_ADD_SUBLIMATION_TO_FWBUDGET.
1108      - bug fix : missing part to Martin's r_FWbySublim pathological case fix.
1109    o verification 1D_ocean_ice_column:
1110       made model domain truly 1x1x23 instead of 5x5x23 with only center cell (3,3,:) wet
1111       update results
1112    o pkg/diagnostics:
1113     - Implement setting of "Post-Processed" diagnostics (corresponding to gdiag(5)='P')
1114       which are not filled-up but computed from other diags ; In this case, the mate
1115       diag points to the primary (filled-up) diag to used for post processing.
1116     - Update Velocity-potential computation using post-processed diag framework.
1117     ==> Change the ordering of fields and time-periods in MDS output file
1118       when using periodic averaging: now writes one time record with the full set
1119       of fields for this time period, then the next time reccord (it used to be
1120       one field with the full set of time records then the next field).
1121         Note: this is now similar to NetCDF (MNC) output file. <==
1122    
1123    checkpoint62z (2011/06/21)
1124    o adjoint monitor:
1125     - Add adjoint monitor output for packages exf, seaice
1126       and update relevant testreport output
1127    o pkg/seaice:
1128     - re-order diags inits so that they appear in order in available_diagnostics.log
1129     - added diags: hsnow thermo. rates of change, area preceeding ridiging process,
1130       area/heff/hsnow preceeding thermodynamic growth/melt.
1131     - modified diag: SIdA; output actual effect, as the description states.
1132     - modified description: SIqneti, SIqneto, SIuheff, SIvheff, SIdAb*, HSNOW.
1133     - retired redundant diags: SIyneg, SIfice, SIsnwice, SIthdgrh.
1134       (SIyneg->SIdHbOCN; SIfice->SIdHbATC; SIsnwice->SIdHbFLO;
1135        and SIthdgrh->SIdHbOCN+SIdHbATC+SIdHbATO)
1136     - modified diags (2) : switch all SIdA*, SIdH*, SIdS* from delta to rates.
1137     - added diagnostics for seaice generic tracers (SItr*).
1138     - added SItrUnit and SItrNameLong run time param (for SItr* diags).
1139     - in diag names, replaced 'PrTh' abbrev. of 'preceeding thermo' with 'PT'.
1140     I. Fenty: 18-Jun-2011:
1141     Minor changes to seaice package:
1142     1) Retired old variables (A22, SEAICE_lhsublim, areaMax, areaMin, hiceMin) and
1143        added some new ones (SEAICE_area_reg, SEAICE_hice_reg, SEAICE_area_floor)
1144       - Differentiated "regularization variables" from "floor variables"
1145        * areaMin became SEAICE_area_reg (old A22) and SEAICE_area_floor
1146        * hiceMin became SEAICE_hice_reg (old hiceMin)
1147          (with _reg meaning regularization variable)
1148       - SEAICE_lhSublim becomes lhSublim, the sum of SEAICE_lhEvap and SEAICE_lhFusion
1149        so as to ensure energy conservation when going between phases
1150      - A22 was not used anywhere
1151     2) Changed regularization procedure for heffActual and hsnowActual to ensure
1152        well-boundedness and smooth adjoint in seaice_growth.F
1153     3) Fixed a bug where seaice_solve4temp would not recognize ice-free grid cells
1154        because the old regularization always set heffActual >= 0.05 cm
1155     4) Changed the model so that the default behavior is to put a small (10^-5) "floor"
1156        on AREA when HEFF > 0.
1157      - went from requiring ALLOW_PRECLUDE_INFINITESIMAL_AREA to be defined to
1158        requiring that DISABLE_AREA_FLOOR *not* be defined
1159     Affected verifications:
1160      - 1D_ocean_ice_column (output.txt output_adm.txt)
1161      - global_ocean.cs32x15 (output.seaice.txt output_adm.seaice.txt)
1162    o pkg/diagnostics:
1163      - move MNC code from diagnostics_out.F into new diagnostics_mnc_out.F (2 S/R).
1164      - rename S/R GETDIAG to DIAGNOSTICS_GET_DIAG and change type of 1rst argument
1165        (was _RL, now integer) with option = 0 to retrieve all levels.
1166      - add pieces of code to compute velocity potential at each level (new diagnostics
1167        PhiVEL, works only when UVELMASS & VVELMASS are also turned on);
1168        for now, using same params as CG2D (target-resisual, max Nb of iter ...).
1169      - fix few issues with counter diagnostics in diagnostics_setdiag.F &
1170        diagstats_setdiag.F (if diagnostic counter is itself a counter diag)
1171        and in diagnostics_fract_fill.F (do not need a valid pointer for the
1172        diagnostics counter-mate); check that definition of counter-diagnostic
1173        includes a valid counter-mate (in diagnostics_set_levels.F).
1174    o model/src (rStar):
1175      - add rStar scaling factor in diags_phi_hyd.F (similar to calc_grad_phi_hyd.F);
1176        affect solution only if z* with full pressure in EOS;
1177        update output of test-exp global_ocean.90x40x15.
1178    o pkg/seaice:
1179      - introduce siEps=1e-5 parameter
1180      - use areaMax in AREA update (part 4), consistent with ridging step (part 2.5).
1181      - re-organize SEAICE_ADD_SUBLIMATION_TO_FWBUDGET code.
1182      - introduce ALLOW_SITRACER and seaice_tracer_phys.F to handle generic seaice tracer.
1183        For now it covers, and was tested for, ice salinity and age (attached to HEFF),
1184        as well as ice cover age and ridging index (attached to AREA).
1185        For now the run time parameters (in data.seaice/SEAICE_PARM03) are
1186        SItrName (e.g. 'age') and SItrMate ('HEFF', which is the default, or 'AREA').
1187        Up to SItrMaxNum=3 tracers can be used simultaneously.
1188    o pkg/salt_plume:
1189      -introduce SPsalFRAC run time parameter that sets the fraction of the
1190       salt by-product of ice growth (SPsalFRAC*(1-SIsalFRAC)*salt typically)
1191       that gets vertically redistributed (fluxed down) by pkg/salt_plume.
1192    o model debug options:
1193      - Switch reading of debugMode from S/R INI_PARMS (parameter file "data", stored
1194        in PARAMS.h) to S/R EESET_PARMS (parameter file "eedata", stored in EEPARAMS.h).
1195      - Refine debug-msg printing selection (3 new levels):
1196        debugMode  : controls printing of debug messages (sequence of S/R calls).
1197        debugLevel : controls printing of algorithm-relevant auxiliary/debug messages
1198         debLevZero =  0 ; /* level of disabled aux. msg printing */
1199         debLevA =  1 ; /* level of minimum  aux. msg printing */
1200         debLevB =  2 ; /* level of low aux. print (report read-file opening)*/
1201         debLevC =  3 ; /* level of moderate debug prt (most pkgs debug msg) */
1202         debLevD =  4 ; /* level of enhanced debug prt (add DEBUG_STATS prt) */
1203         debLevE =  5 ; /* level of extensive debug printing */
1204        New debugLevel default: with default debugMode value (=F),
1205          = 2 (debLevB) or = 1 (debLevA) in case ALLOW_AUTODIFF is defined.;
1206          and if debugMode=T, default debugLevel = 4 (debLevD).
1207        Relation with previous settings:
1208         debLevB (=2) corresponds to former debLevA (=1)
1209         debLevD (=4) corresponds to former debLevB (=2)
1210        Note:
1211         a) if debugLevel=0, skip WRITE_GRID call when nIter0 > 0 (same as before);
1212         b) default debugLevel=1 is convenient in AD runs (avoid many file opening msgs);
1213            to recover previous default, set debugLevel=2 (e.g. AD-test hs94.1x64x5)
1214      - Add new parameter (printResidualFreq, read from PARM02 namelist) to print
1215        detailed CG solvers convergence; off (=0) by default, except if debugLevel=5.
1216    o pkg/obcs:
1217      - change OBCSfixTopo default from True to False (should not change the results);
1218        keep OBCSfixTopo=T in verification-exp. seaice_obcs.
1219    o pkg/thsice:
1220      - fix bug in thsice_calc_thickn.F (was introduced in version 1.18) in
1221        2nd layer seaice sublimation (unlikely to happen)
1222      - use Interior mask for OBCS in thsice_advection.F (similar to what is
1223        done in gad_advection & seaice_advection).
1224    o adjoint:
1225      bug fix spotted by Gael Forget:
1226      seaice_advection and thsice_advection still had
1227      legacy CPP options to avoid CS corner updates for adjoint
1228    o pkg/seaice:
1229      => Change some of the defaults (2011/05/29):
1230         - change SEAICEuseFluxForm default (from False to True)
1231         - change DIFF1 default (from 0.004 m/s to 0. m/s)
1232         And print warnings if DIFF1 is not set in data.seaice and centered
1233          avection scheme is used without any diffusion.
1234      also:
1235      - fix seaice_diffusion calls in default AdvScheme part of seaice_advdiff.F;
1236      - set SEAICEdiffKh[] default in the same way as SEAICEadvSch[]
1237      - stop if DIFF1<>0 with SEAICEadvScheme <> 2, if DIFF1<>0 with any
1238        other non-zero SEAICEdiffKh[] diffusivity, if SEAICEadvSalt=T with
1239        #undef SEAICE_VARIABLE_SALINITY, if SEAICEadvAge=T with #undef SEAICE_AGE.
1240      update results of test exp.:
1241         lab_sea: output.fd (switch to AdvScheme=33 with diffKh=20)
1242             output.hb87, output_adm.evp (SEAICEuseFluxForm=T and diffKh=200)
1243             output_adm.noseaicedyn (SEAICEuseFluxForm=T)
1244         offline_exf_seaice: output.seaicetd, output_adm (SEAICEuseFluxForm=T)
1245         seaice_obcs: output (SEAICEuseFluxForm=T)
1246      and prescribe old default for SEAICEuseFluxForm (=F) and DIFF1 (=0.004)
1247          for standard fwd & AD lab_sea tests (to keep the same output).
1248    o pkg/seaice/seaice_growth.F:
1249      - use Ian Fenty's capping formulas for actual ice
1250      thickness thoughout EVOLUTION branch.
1251      - put treatment pathological case #2) in CPP brackets
1252      (ALLOW_AVOID_INFINITESIMAL_AREA, undef by default).
1253      - update global_ocean.cs32x15 and 1D_ocean_ice_colum results accordingly.
1254    o pkg/seaice:
1255      - seaice_diffusion.F : remove the min(DX,DY) factor permanently;
1256      pass the Laplacian diffusivity (in m^2/s) diffKh as a parameter;
1257      also pass fac as a param, which can be 1. (to update the tendency
1258      field) or the time step (to update the field itself).
1259      - seaice_advdiff.F: for multidim, call seaice_diffusion with
1260      e.g. SEAICEdiffKhHeff and with fac=1; for single-dim, call
1261      seaice_diffusion with e.g. SEAICEdiffKhHeff and with fac=time step.
1262      - SEAICE_PARAMS.h, seaice_readparms.F, seaice_check.F :
1263      hooks to handle SEAICEdiffKhHeff, SEAICEdiffKhArea, etc.
1264    o pkg/seaice:
1265      diffusion with centered advection scheme (diffus.F & advect.F):
1266      - simplify S/R DIFFUS (put deltaT & DIFF1 factor outside, move EXCH outside)
1267        to just compute the laplacian of input-field.
1268      - unroll k loop (harmonic,biharmonic diff) in advect.F to save 1 exch call.
1269      - fix flux-form version in diffus.F to conserve tracer.
1270      update output of lab_sea.fd & lab_sea.hb87 (1rst set of modif affects
1271       machine truncation) and lab_sea.salt_plume (conservative flux-form modif)
1272    
1273    checkpoint62y (2011/05/26)
1274    o pkg/seaice:
1275     - seaice_growth.F : in EVOLUTION branch, always include
1276       a_QSWbyATM_cover in qnet (as it should be).
1277     - verification/global_ocean.cs32x15 : update results accordingly
1278       (output.seaice.txt output_adm.seaice.txt).
1279    o pkg/seaice + obcs:
1280     - use maskInW & maskInS in multi-dim advection and biharmonic diffusion:
1281       equivalent of assuming no tracer gradient outside the OB region.
1282       update output of seaice_obcs (uses DIFF1 <>0 => biharmonic diffusion)
1283     - remove calls to OBCS_COPY_TRACER after EXCH calls (no longer needed
1284       after changes above);
1285     - obcs+seaice cleaning: apply seaice-tracer OB values to tracer field
1286       only at OB location (instead of over a band of OLx width).
1287    o pkg/seaice:
1288     - fix wrong indices in old (non Flux-Form) diffusion default S/R diffus.F
1289       (dxG(I+1, ...) changed to dxG(I, ...), no impact on Lat-Lon grid)
1290    o pkg/obcs:
1291      - split header file "OBCS.h" into 4 separated files:
1292        OBCS_PARAMS.h, OBCS_GRID.h, OBCS_FIELDS.h & OBCS_SEAICE.h
1293       Note: OBCS_PARAMS.h & OBCS_GRID.h can be included without OBCS_OPTIONS.h
1294         (contain no conditional statement which depends on OBCS options).
1295      - move "useOBCSYearlyFields" from "data.obcs" (hold in OBCS_PARAMS.h)
1296        to parameter file "data.exf", namelist EXF_NML_OBCS (in EXF_PARAM.h).
1297    o ctrl, cost, grdchk & autodiff pkgs:
1298      - make options file more standard (like other {PKG}_OPTIONS.h file but
1299        with AD_CONFIG.h); clean-up some of the included header files.
1300    o pkg/obcs:
1301      - do not mask tracer when applying OB (tracer == 0 could generate problems)
1302      - apply tracer OB values to tracer field only at OB location (instead of
1303        over a band of OLx width)
1304      - clean-up obcs_apply_w.F & obcs_apply_eta.F (since less calls to these S/R)
1305      - remove OBCS_MULTIDIM_OLD_VERSION code in gad_advection.F and remove
1306        obcs_apply_tloc.F & obcs_apply_sloc.F
1307    o obcs in model/src:
1308      - call OBCS_APPLY_W only if NonHydrostatic.
1309      - call OBCS_APPLY_ETA only if NonLinFreeSurf.
1310      - reset dEtaHdt and wVel to zero outside OB interior region ;
1311      - leave tracer unchanged outside OB interior region: This has no effect
1312        on the solution but just to prevent unrealistic tracer value outside OB.
1313      - zero out velocity outside OB interior region: This has no effect on
1314        the solution but just to prevent unrealistic velocity outside OB.
1315    o obcs and non-lin free-surf:
1316       move call to OBCS_APPLY_R_STAR from update_r_star.F to calc_r_star.F
1317       and call to OBCS_APPLY_SURF_DR from update_surf_dr.F to calc_surf_dr.F
1318       + add argument "etaFld" to OBCS_APPLY_R_STAR & OBCS_APPLY_SURF_DR:
1319       this fixes missing EXCH + get consistent eta OB value (+ fix restart).
1320       update results of test-exp. exp4(nlfs).
1321    o exp4 (nlfs) test-exp:
1322       use OBC for Eta at Western & Eastern OB (to test prescribing Eta
1323       with NonLin-FreeSurf); update output.nlfs.txt
1324    o obcs and 2d/3d solver norm:
1325       use interior masks (maskInC) to cancel out cg2d & cg3d matrix coeff at OB
1326       and outside OB interior region (will allow to place OB further inside the
1327       domain). Depending on the domain, can affects cg2d-Norm (previous
1328       cancellation outside OB was only partial), e.g. in exp4 & obcs_ctrl,
1329       and cg3d-Norm (previous Norm was computed before canceling OB terms),
1330       e.g. in tutorial_plume_on_slope.
1331      - update output of exp.: exp4 (x2), obcs_ctrl and tutorial_plume_on_slope.
1332    o pkg rbcs:
1333      - split RBCS.h into 3 files: RBCS_SIZE.h, RBCS_PARAMS.h & RBCS_FIELDS.h
1334      - add capability to apply relaxation to horizontal velocity uVel & vVel.
1335    o pkg/grdchk: add gradient check for control variable xx_shifwflx
1336    o pkg/shelfice/shelfice_init_fixed.F
1337      fix CPP-flag combinations
1338    o pkg/seaice: Merge iceage code of Pierre Rampal
1339      * update/change/correct ice age calculations
1340      * add age updates for pathological cases
1341      Probably needs more testing...
1342    
1343    checkpoint62x (2011/05/13)
1344    o pkg/mom_vecinv:
1345       high-order vorticity scheme: use interior masks (maskInW & S)
1346       to zero-out (outside OB) gradient of vorticity.
1347    o verification exp.:
1348       turn on "useEnergyConservingCoriolis" (better discretisation) in exp.
1349       hs94.128x64x5 and seaice_obcs ; update results.
1350    o pkg/obcs:
1351      fix bug in OBeta for YZ sections in obcs_exf_load.F
1352    o pkg/ctrl, pkg/shelfice, and optim:
1353      - add new control variable xx_shifwflx (fresh water flux underneath ice
1354        shelves). This is almost as tedious as obcs-ctrl, because the
1355        variables needs its own mask.
1356      - add a cost function term that penalizes the deviation of xx_shifwflx
1357        from the first guess (zero) in analogy to other control variables
1358    o pkg/shelfice:
1359      - start basic adjoint
1360    o pkg/ctrl:
1361      - remove extra 2D field "for good measure" when initializing in
1362        ctrl_set_globfld_[xy/xz/yz].F
1363      - replace hard coded precision 32 (a bug) in ctrl_map_ini_gen by ctrlprec
1364      - improve error messages in ctrl_set_unpack_*
1365    o OBC implementation in momentum:
1366       use interior masks (maskInC,W & S) in momentum S/R:
1367       - multiply divergence, tension and some del^i.u or del^j.v by maskInC
1368       - multiply del2u,del2v by maskInW/S (biharmonic viscosity)
1369       - multiply horiz. grad of vorticity by maskInW/S (in Leith scheme)
1370       - multiply gradient of wVel by maskInW/S in del2w calculation (NonHyd)
1371       Motivation: fix/clean implementation of OBC with biharmonic-viscosity
1372        (and also with Leith/Smagorinsky harmonic-viscosity).
1373       Update output of experiment dome and exp4 (+nlfs).
1374    o exp4 test-exp:
1375      - turn on: nonHydrostatic, exactConserv, viscA4 (with momDissip_In_AB=F)
1376        and prescribe time-varying OB (without pkg/exf) for zonal-velocity
1377        at Western & Eastern Boundaries (+/- 1 per-cent); Also prescribe
1378        time-varying OB at Western-side for wVel (NonHyd); update output.
1379      - add secondary set-up (.nlfs) using NonLin FreeSurf (z*) + mom_vecinv
1380        and biharmonic-viscosity ; also use prescribed time varying OB.
1381    o pkg/obcs:
1382      fix bug in OBWeta,OBWeta indices in obcs_apply_r_star.F
1383    o model/src:
1384      - fix startTime setting when baseTime<>0 & nIter0=0 are specified ;
1385      - initialise startTime & nIter0 with unlikely values: allows to set one
1386        from the other without ambiguity.
1387    o seaice_obcs test-exp.:
1388      add small diffK4T,S to test biharmonic diffusivity with OBCS ; update output.
1389    o pkg/obcs:
1390      - remove calls to OBCS_COPY_TRACER after EXCH for T,S & pTracer:
1391        no longer needed with maskInC,W,S in pkg/generic_advdiff.
1392    o pkg/seaice:
1393      - retired SEAICE_SALINITY and SEAICE_salinity in favor of
1394        SEAICE_VARIABLE_SALINITY and SIsalFRAC, respectively.
1395      - fixed bug in the initialization of sea ice salinity variable HSALT
1396        in seaice_init_varia.F  (removed dependence on ICE2WATR)
1397    o fizhi-cs test exp.:
1398       switch reference output convention for these 2 non-standard test-exp,
1399        from: pgi  6.1-5 on faulks (FC.6, -of linux_ia32_pgf77+authors_fc5)
1400          to: ifort 11.1 on baudelaire (FC.13, -of linux_amd64_ifort11)
1401       reason: faulks might get retired soon and pkg/fizhi has still Pb with gfortran
1402    o model/inc:
1403      - change type of PmEpR array (from _RS to _RL) to fix restart (with "-use_r4")
1404        of exp. global_ocean.90x40x15 (Suncronous time-stepping + Real-FW + NonLin-FS)
1405    o pkg/seaice:
1406      - fix calculation of saltFlux and saltPlumeFlux when using SEAICE_SALINITY
1407    o verification/lab_sea, 1D_ocean_ice_column, seaice_obcs, global_ocean.cs32x15
1408      - updated output*.txt files due to bug fixes in salt, saltPlumeFlux,
1409        and initial HSALT
1410    
1411    checkpoint62w (2011/04/26)
1412    o pkg/mom_fluxform:
1413      - fix calculation of del2u & del2v (no-slip BC) when using Non-Lin Free-Surf.
1414      - use parameter "sideDragFactor" in no-slip BC side-drag part.
1415      - update output of exp. global_ocean.90x40x15
1416    o pkg/mom_vecinv:
1417      mask del2u & del2v (no effect on results, but cleaner & closer to mom_fluxform)
1418    o update seaice exp.:
1419      use more consistent parameter values (remove "backward compatability only":
1420       ICE2WATR, SEAICE_lhSublim, SEAICE_cpAir, SEAICE_rhoAir + set rhoConstFresh)
1421      related to thermodynamics seaice. Update output (fwd+AD) of exp.:
1422       1D_ocean_ice_column (x2), lab_sea (x8), ioffline_exf_seaice (x2) & seaice_obcs
1423    o update test-exp global_ocean.90x40x15:
1424      o use default CD_CODE_OPTIONS file (Adams-Bashforth on CD Mom & Coriolis).
1425      o increase Overlap size from 2 to 3 (to allow to test bi-harmonic Visc.)
1426      o new pickup-files from a 100.yr run with pkg/down_slope (input.dwnslp params)
1427      o turn on zStar & viscA4 in standard set-up (dir input/)
1428        and update output files: output.txt & output.dwnslp.txt
1429    o new AD-test experiment: obcs_ctrl
1430      (From Matt MITgcm_Contrib/SOSE/BoxAdj) to test OBCS as control vector.
1431    o pkg/dic:
1432      fix two bugs in handling water vapour pressure in carbonate chemistry
1433      and air-sea fluxes. Found by Val Bennington and Galen McKinley
1434      (add DIC Option = WATERVAP_BUG to recover old results)
1435      update output of tutorial_global_oce_biogeo (fwd+AD) & tutorial_dic_adjoffline
1436    o adding allowInteriorFreezing option to check for water below freezing point
1437      at depth and bring the negative heat anomaly to the surface level
1438    o pkgs _fields_load:
1439      - extend GET_PERIODIC_INTERVAL to deal with non-periodic case (from pkg/rbcs)
1440      - use new S/R GET_PERIODIC_INTERVAL in pkgs:
1441        bulk_force, cheapaml, cfc, dic, obcs (+ ctrl/ctrl_get_gen_rec), offline and
1442        rbcs to get interpolation weights and time reccord number.
1443      - fix multi-threading in aim_fields_load.F
1444      - apply EXCH to temp arrays [0,1] after reading in dic_fields_load.F
1445    o external_fields_load:
1446      new S/R GET_PERIODIC_INTERVAL to calculate which time-record (and linear
1447       interpolation weights) to use in a periodic time-series ; do not divide by
1448       time-step to convert to integer:
1449       - this fixes case where externForcingPeriod is not multiple of time-step
1450          (Thanks to Christopher L. Wolfe)
1451       - this fixes case where externForcingPeriod is an odd multiple of time-step
1452         (was wrong by half of time-step); update results of tutorial_global_oce_in_p.
1453      store index of time-record which is currently loaded:
1454       - works without any assumption on sequence of calls to EXTERNAL_FIELDS_LOAD ;
1455       - needed for the adjoint but not yet used because of extensive recomputations;
1456         (to be fixed soon)
1457    
1458    checkpoint62v (2011/04/02)
1459    o verification/1D_ocean_ice_column added to test Ian Fenty's
1460      pkg/seaice_growth.F modifications for improving sea ice code differentiability
1461    o update output of exp4, internal_wave, seaice_obcs, tutorial_plume_on_slope
1462      (new velocity statistics after changing maskInW & maskInS definition)
1463    o pkg/generic_advdiff with OBCS:
1464      use maksInW & maskInS in advective flux and in biharmonic diffusion calculation:
1465      equivalent to assumption of no tracer gradient outside the OB region.
1466      This will affect the results if using obcs+biharmonic diffusion.
1467      update output_adm.txt of experiment bottom_ctrl_5x5 (not expected since no obc)
1468    o pkg/obcs:
1469      change definition of maskInW & maskInS: leave OB edges inside (maskIn=1)
1470      (e.g., maskInW(OB_Ie)=1 ) so that velocity normal-component at OB is still
1471      in Interior region. No impact on solution but affects Velocity monitor stats.
1472    o pkg/ptracers (adjoint)
1473      New option AUTODIFF_PTRACERS_SPLIT_FILES for writing separate
1474      tape file for each tracer
1475    o model/inc/src and pkg/autodiff: add parameters that allow to turn
1476      of parts of the adjoint code at run time. For now, there are only
1477      useKPPinAdMode, useGMrediInAdMode, and useSEAICEinAdMode. These
1478      parameters are set in data.pkg.
1479      This is the lazy coward's version of doing this, but still useful for
1480      debugging. In order to do it right, everything needs to be moved to
1481      pkg/autodiff.
1482    o pkg/autodiff: fix global_sum_tile_ad.F by resetting adsumPhi at
1483      the end; this fixes the adjoint balancing code for open boundaries.
1484    o pkg/ctrl:
1485      - change behavior of xx_${varname}period to be analogous to exf-conventions:
1486        xx_${varname}period =   0.,  means time-independent control part
1487        xx_${varname}period = -12., means one-year-periodic monthly control part
1488      - introduce helper routine ctrl_init_rec (part of ctrl_init.F) to
1489        clean up ctrl_init a little, remove unused variables
1490      - ctrl_init: fixed the handling of the start/endrec for obcs-variables
1491      - move "call cal_GetMonthsRec" from s/r ctrl_get_gen to s/r ctrl_get_gen_rec
1492    
1493    checkpoint62u (2011/03/15)
1494    o model/src:
1495      - for the adjoint, change NonLin-FreeSurf initialisation sequence: fill-in
1496        h0Fac from INITIALISE_FIXED and reset hFac to h0Fac in INITIALISE_VARIA ;
1497      - in initialise_varia.F (except for ALLOW_DEPTH_CONTROL) remove 2nd call to
1498        INI_DEPTHS, INI_MASKS_ETC & INI_LINEAR_PHISURF.
1499    o pkg/ctrl/obcs/ecco:
1500      - remove obsolete, unused, and partially broken code:
1501        ctrl_obcsvol/ctrl_obcsbal/ctrl_volflux and code within
1502        ALLOW_CTRL_OBCS_BALANCE
1503      - put a stop statement into ecco/cost_obcsvol.F, but also add
1504        cost_obcsvol to ecco_ad_diff.list
1505    o pkg/ecco: fix counting cost function contributions for obcs (code
1506      by Matt M.) and diffkr for diagnostics
1507    o pkg/ecco, pkg/ctrl, pkg/grdchk:
1508      add cost penalty terms for initial uvel, vvel, eta controls
1509      and I/O for prior error files
1510    o pkg/mdsio:
1511       move mds_check4file.F from eesupp/src to mdsio_check4file.F ; add option
1512       (new argument) to check for tiled file in mdsioLocalDir : this fix the
1513       restart from pickup_som , pickup_dic (& dic_co2atm) with mdsioLocalDir.
1514    o pkg/ctrl:
1515     - ctrl_obcsbal.F, ctrl_obcsvol.F: replace last calls of ctrl_getrec by
1516       ctrl_get_gen_rec, put a stop statement into ctrl_getrec. Remove
1517       unused and superfluous variables
1518     - ctrl_get_gen_rec.F: catch the case of xx_genperiod=0.
1519    o pkg/ecco
1520     - enable adjoint of Stevens OB
1521    o pkg/ctrl/ecco/grdchk:
1522      - remove global declaration of tmpfldx/yz and tmpfldx/yz2.
1523        Fortunately, we do not have any tests for the numerous cpp-flagged
1524        option of "obcs as control parameters" so we will never know
1525        if this is an improvement (but at least now things compile).
1526      - remove an obsolete initialization from ecco_cost_init_barfiles.F
1527      - fix some problems within never used ifdefs to make the code compile
1528    o pkg/obcs:
1529     - Refine Interior mask definition to work with more complex OB (e.g.
1530       if OB_Ie < OB_Iw); In case default setting is not sufficient, allows to
1531       read in Interior mask from file. Check if Interior mask is consistent
1532       with OB list of indices.
1533    o pkg/seaice
1534     - beginning code for a seaice tracer package,
1535       but currently only used for seaice age: SEAICE_AGE
1536       SEAICE_num = 4
1537       iTracer = 1: area-weighted ice age
1538               = 2: volume-weighted ice age
1539               = 3, 4: template for one-year vs. multi-year ice
1540       data.seaice has new namelist SEAICE_PARM03 for arrays related to
1541       SEAICE_num
1542    
1543    checkpoint62t (2011/03/05)
1544    o pkg/obcs:
1545     - obcs_apply_uv.F: change to a 2 steps method, first tangential component;
1546       then normal component. This ensures that the normal component is set
1547       correctly even when it conficts with tangential setting from an other OB.
1548       Affects results of test-experiment seaice_obcs: update the output.txt
1549    o pkg/obcs:
1550     - add code to monitor statistics of dynamical fields at OB.
1551     - take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW :
1552       - fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection).
1553       - change default: balance the Net inflow through all OB (instead of balancing
1554         each OB separately); keep the old method if setting OBC_balanceFacX < 0.
1555     - switch on useOBCSbalance in dome experiment: only correct Western OB outflow
1556       to match Nortern OB inflow (OBCS_balanceFacN=0).
1557    o pkg/seaice:
1558     - redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL
1559    o pkg/seaice (seaice_growth v 1.113):
1560     - reverting seaice_growth to v 1.111 in order to have code with exact bit
1561       compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge
1562       CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced
1563       runtime flag SEAICEareaFormula is kept but is inactive
1564    o model/src:
1565     - add new param to scale curvilinear grid distance and area when using
1566       a different sphere radius from the grid-files.
1567     - test/check multi-threads EXCH applied to local variable (cg2d_x)
1568    o adjoint:
1569     - enable adjoint of Stevens OB
1570     - add dummy_in_dynamics to enable extraction of ADJrhoinsitu
1571       (a bit delicate because of potentially modified adj. common block structure;
1572       current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later)
1573    
1574    checkpoint62s (2011/02/15)
1575    o pkg/seaice (seaice_growth v 1.112):
1576     - introduce SEAICEareaFormula run time parameter, which selects the recipe for
1577       computing the ice cover tendency from effective thickness tendencies. Include
1578       Ian Fenty's formula.
1579     - remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using
1580       SEAICEareaFormula.
1581     - simplify notations for the various d_HEFF/d_AREA terms.
1582    o pkg/gmredi:
1583     - add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code
1584       from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative;
1585       add a verification test-run (front_relax.bvp) to test GM_useBVP.
1586    o pkg/seaice (seaice_growth v 1.111):
1587     - for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's.
1588     - the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to
1589       also melt ice.
1590    o pkg/seaice:
1591     - McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty).
1592     - can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h
1593    o pkg/cheapaml:
1594     - from Nico Wienders: New version of this package.
1595    o pkg/flt:
1596     - add CPP options to prevent floats to re-enter the opposite side of
1597       a periodic domain (default: keep periodicity)
1598    o pkg/gmredi:
1599     - apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners
1600       (needed for multi-dim advection).
1601     - switch on GM Advective form in global_ocean.cs32x15 and update output.txt
1602    o model/src:
1603     - fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run.
1604    o tutorial_tracer_adjsens
1605     - extend to NLFS and replace maskC by hFacC
1606       (change reference output accordingly)
1607    
1608    checkpoint62r (2011/01/24)
1609    o testreport:
1610     - add option -deloutp (-do) to remove output file after successful run
1611     - add option -mfile (-mf) for MPI machile-file and for each test-exp,
1612       extract exact list of procs from this file ; adjust COMMAND by
1613       replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs.
1614    o pkg/ecco: replace old ineffective way of penalizing deviations from
1615      first guess (of obcs) with code by Matt Mazloff
1616    o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without
1617      exf/cal
1618      - ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl
1619        and handle case of obcs?period == 0
1620        Not affected by these changes: There is still an inconsistency in
1621        the computation of start/endrec for the obcs variables for ALLOW_CAL
1622        defined (see comment by Menemenlis, 7-Mar-2003)
1623      - make S/R ctrl_get_gen_rec return something meaningful even if
1624        ALLOW_CAL is not defined
1625      - ctrl_getobcs?: simplify code so that it does not need to use
1626                       S/R exf_swapfields
1627    o testreport:
1628       allow to test MPI with different number of processors for each experiment:
1629       create file "SIZE.h.mpi" in each build dir.
1630       Note: update of "-command" argument not yet implemented.
1631    o model/src, pkg/autodiff, pkg/ecco, pkg/seaice:
1632      alleviate the need for additional 3D tapes when using
1633      the non-inear free surface in the adjoint. This is done
1634      by adding an 'update' of hfacc etc. to their current
1635      value at the beginning of forward_step.F.
1636    o pkg/seaice
1637      seaice_lsr: move stress-divergence computations out of outer pseudo-
1638      timestepping loop
1639    o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD'
1640      up, so that the calls of the ctrl_* subroutines are really at the end
1641      of the routine.
1642    o pkg/gmredi:
1643      allow to specify a 2-D horizontal map and a 1-D vertical profil
1644      as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity.
1645    o pkg/seaice:
1646      move lsr iterations from seaice_dynsolver to seaice_lsr.
1647    o pkg/seaice:
1648      reduce memory footprint of seaice mutldim advection tapes,
1649      by using a 2D tape independent of the generic_advdiff ones,
1650      and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc.
1651    
1652    checkpoint62q (2010/12/29)
1653    o model/src:
1654      - check horizontal grid-spacing for unset or zero/negative values.
1655      - change AD test hs94.1x64x5 to be truly a 2-D set-up.
1656    o pkg/flt:
1657      - use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR
1658      - precision of input and output files set according to readBinaryPrec
1659        and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits.
1660      - initial float position from tiled file was not converted to index space
1661        (looks like a bug): fixed to make it similar to initial pos. global file.
1662    o global_ocean.cs32x15:
1663       change SIZE.h of AD set-up to get same tiling as with MPI.
1664       Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11)
1665    o model/src:
1666       add flag to control printing of domain fields (bathymetry, hFac ...) in
1667       ini_mask_etc (call to plot_fieds_xy*).
1668    o pkg/thsice:
1669       if useEXF, some forcing fields are not valid in overlap: fixed by computing
1670       over the interior only + apply EXCH at the end (like with SEAICE advection).
1671    o pkg/mdsio:
1672      - add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer
1673        to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS.
1674      - change barrier call for safe multi-threads access to 3-D shared buffer.
1675      - MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones)
1676      - replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and
1677        remove the 4 S/R MDS_PASS_WH_R4/8toRL/S.
1678    o pkg/flt:
1679      - add fourth-order Runge-Kutta integration
1680      - add basic exch2 support (only 1 facet supported so far!)
1681    o pkg/mdsio+rw:
1682      new S/R to read local (or tile independent) vector (read counterpart of
1683       mds_writevec_loc, and front-end write_glvec_rl/rs).
1684    o global_ocean.cs32x15: additional input_ad.seaice experiment
1685        that uses pkg/seaice rather than pkg/thsice.
1686        (using multidim advection for seaice)
1687    o towards more F95 syntax for array specification in namelist:
1688      - change "data.diagnostics" (data.ptracers was changed before checkpoint62p)
1689        of all verification experiments.
1690           e.g.:    line: fields(1,3)='ETAN    ','ETANSQ  ',
1691          was changed to: fields(1:2,3)='ETAN    ','ETANSQ  ',
1692      - finish adding "-DNML_EXTENDED_F77" to DEFINES list in pgf77 and g77 optfiles
1693    o global_ocean.cs32x15: additional input.seaice experiment
1694        that uses pkg/seaice rather than pkg/thsice.
1695    
1696    checkpoint62p (2010/12/17)
1697    o pkg/thsice: rename (ad tape index) iicekey as ticekey, and move it
1698        to THSICE_SIZE.h to avoid conflict with pkg/seaice.
1699    o pkg/seaice: add seaice_diffusion.f seaice_map_thsice.f to adjoint.
1700        allow for use of multim. advection in seaice adjoint.
1701    o pkg/seaice: add diagnostics for snow precipitation and sublimation flux
1702      - first attempt to close budgets by taking into account the freshwater
1703        flux implied by the sublimation of snow and ice. So far only the
1704        volume budget is closed, turn on with soon-to-be-retired-again CPP-Flag
1705        SEAICE_ADD_SUBLIMATION_TO_FWBUDGET
1706    o eesupp/src:
1707      new S/R with new option (NML_EXTENDED_F77) to change array specification
1708      from F95 standard to commonly accepted extended F77 form.
1709      This would allow to use F95 syntax in namelist (needed with gfortran 4.4.5)
1710      and to revert back to the original syntax (with -DNML_EXTENDED_F77)
1711      for less tolerant f77 compiler (e.g., pgf77, g77).
1712    o globalFiles:
1713      commented out in parameter file "data" since it's not safe with MPI
1714      (e.g., wrong on aces); keep it if useSingleCpuIO=T (but not doing much
1715      in this case); no longer commented out in restart test (tst_2+2).
1716    o add adTapeDir to specify a special directory where adjoint tapes are
1717      written/read (adread_adwrite.F). adTapeDir is specified in data/PARM05
1718      and cannot be used together with mdsioLocalDir.
1719    o nesting pkgs:
1720      - packages_init_variables : put call to OBCS_INIT_VARIABLES in last position
1721      - update Gianmaria's Nesting pkgs (from Contrib/nesting_sannino)
1722      - add parameter files + utils dir + output from short run on beagle.
1723    o pkg/seaice:
1724        fix seaice_growth.F store directives; update results of exp. lab_sea.ad
1725    o pkg/seaice: explicitly store tsurfloc in seaice_solve4temp.F to avoid
1726      unnecessary copying in adjoint code, requires new parameter NMAX_ITER
1727    
1728    checkpoint62o (2010/11/25)
1729    o pkg/exf:
1730      - change CPP option EXF_VERBOSE to run-time logical param exf_verbose.
1731    o pkg/seaice:
1732      - seaice_ocean_stress: split a loop for better vectorization of the
1733        adjoint code
1734      - seaice_growth.F: fix bug in conservation of freshwater connected to
1735        capping of heff, put contribution into d_HEFFbyNEG
1736      - replace irritating parameters SEAICE_latentWater/Ice and SEAICE_sensHeat
1737        by something more sensible (parameters that are what their name implies)
1738      - change some defaults, so that by default exf-parameters are used for
1739        things like rhoAir, cpAir,latent/sensible heat parameters, in order
1740        to reproduce the old results, many data.seaice now contain funny values
1741        for cpAir and latent heat of sublimation
1742    o packages_readparms.F: move exf_readparms up in line so that
1743        exf-parameters are visible for other packages (e.g. seaice)
1744    o debugMode & debugLevel=2:
1745      - differentiate between debugMode & debugLevel=2:
1746        debugMode: controls printing of debug messages (sequence of S/R calls).
1747        debugLevel: controls printing of algorithm intermediate results and stats.
1748      - remove "if debugLevel=2 => debugMode" but keep "debugMode =>  debugLevel=2";
1749        => allows to print debug-stats without all sequence of call messages.
1750      - switch control of debug print from debugLevel to debugMode in many S/R.
1751    o pkg/obcs (obcs-sponge):
1752        fix bug that was introduced on Oct 25 (in dynamics.F v1.151): put back the
1753        call to OBCS_PRESCRIBE_EXCHANGES (need to exch gU,gV when using obcs-sponge)
1754    o pkg/generic_advdiff:
1755      - record overlap minimum size for each advection scheme;
1756      - refine criteria on overlap minimum size;
1757      - check and stop (in gad_check) if overlap size is too small.
1758    o pkg/obcs:
1759      - with ptracers: remove multiple calls to obcs_apply_ptracer (only done
1760        once, in ptracers_implicit.F)
1761      - with seaice: remove test on empty file name in obcs_apply_seaice (always
1762        apply OB values when tile has OB)
1763    o model/src, coriolis setting:
1764      - integer parameter "selectCoriMap" (=0,1,2) replaces 3 logical
1765        useConstantF, useBetaPlaneF, useSphereF ; can now read coriolis from
1766        files (selectCoriMap=3) with any grid.
1767      - add parameter "fPrime" for constant second Coriolis coeff (default=0).
1768    o pkg/seaice/seaice_growth.F:
1769        a few cosmetic changes that reduce the number of lines of code
1770    o pkg/obcs: add boundary conditions following Stevens (1990)
1771      - the code follows old MOM/NAOSIM code
1772      - so far it is only implemented for the eastern and western boundaries
1773        and NOT for pTracers
1774    o pkg/rbcs:
1775      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
1776        beginning of the first rbcs forcing period.
1777      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
1778        offline package, i.e., one file per time, labeled by iteration number;
1779        deltaTrbcs sets the timestep with which the data was generated;
1780        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
1781      - rbcsForcingCycle=0 makes forcing non-cyclic.
1782      - make arithmetic safe for negative times and odd forcing periods.
1783    
1784    checkpoint62n (2010/11/09)
1785    o pkg/seaice:
1786        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
1787    o pkg/obcs:
1788       New S/R to copy tracer value from the OB location to narrow band region
1789        (width = same as overlap) beyond the OB: preserve OB value (needed for
1790        high-order scheme) which were overwritten by EXCH call if in overlap
1791        region. Applied to theta, salt, ptracer and advected seaice variables.
1792       With seaice: use maskInC in similar way as in gad_advection.F,
1793        in seaice_advection.F and advect.F.
1794       Update output of experiment seaice_obcs and change exp4 to test OBCS with
1795        4th order Adv.Scheme. for pasive salt and ptracer.
1796    o tools/genmake2:
1797      - when looking for an optfile (not specified), only search for Fortran compiler
1798        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
1799      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
1800        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
1801      - set default for CPP to "cpp -traditional -P" (was the case without specifying
1802        an optfile, but otherwise default was just "cpp".
1803      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
1804      - when "CC" is not set in the optfile, look for possible C compiler
1805        (instead of just setting CC=cc)
1806      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
1807        => add a ".F" to ".o" rule for source files with no "#include" (such as
1808           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
1809      - move gfortran before g77 in list of possible Fortran compiler (consistent
1810        with reference compiler switch from g77 to gfortran)
1811    o pkg/seaice:
1812      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
1813        seaice_check that stops the model, when the CPP flag is used.
1814      o seaice_growth.F: make capping of ice volume conserving by returning the
1815        capped ice as freshwater to EmPmR. This does not change the verification
1816        experiments but will change runs where the capping is acutally active
1817    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
1818      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
1819         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
1820         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
1821    o tools/genmake2:
1822      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
1823      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
1824      - clean previous genmake log files before anything else.
1825      - change Makefile to remove testreport log files (*.tr_log) and genmake log
1826        files only with "CLEAN" target (instead of "Clean");
1827    o pkg/generic_advdiff:
1828      Change OBCS in multiDim advection (gad_advection.F):
1829       Use maskInC to prevent intermediate update of tracer-field in OB regions,
1830       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
1831       which were applying future time-step OB values.
1832      This way, all explicit calculations use current-time-step OB values
1833       (simpler and more consistent).
1834      Affects results when set-up uses time-varying OBC and multi-dim advection;
1835       update output of experiment seaice_obcs.
1836    o pkg/seaice:
1837      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
1838       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
1839         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
1840      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
1841       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
1842       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
1843    o pkg aim (2010/10/26):
1844      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
1845        formulation with obliquity, eccentricity, ... as run-time parameters,
1846      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
1847        upward shortwave radition at the surface (all-sky and clear-sky).
1848    o pkg/obcs:
1849      - writing sections with globalFiles=T does not work: switch to tiled-files
1850        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
1851      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
1852      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
1853    
1854    checkpoint62m (2010/10/21)
1855    o pkg/seaice: vectorize seaice_solve4temp.F
1856      - move iterations loops outside of i/j-loops
1857      - requires 2D arrays for TB and effConduct
1858      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
1859        modified in this routine
1860      - a little bit of clean up, adjusting indentation, etc.
1861      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
1862        performance and '**TWO' by '**2' (because TWO is a float),
1863        replaced ONE, ZERO
1864    o eesupp/src:
1865       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
1866    o pkg/seaice/seaice_growth.F
1867      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
1868      merging process. The merged routine has two branches, and one activates the 'evolution'
1869      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
1870      In summary, here is what the '10/10 revision' did consist of
1871        part 1: seaice_growth.F revisions 1.71 to 1.75
1872          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
1873            The emphasis here was on improving readability (e.g. by trying to use meaningful
1874            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
1875        part 1.5:
1876          - revising the lab_sea experiment to make it a more useful (i.e. stable
1877            and representative of an actual model run). This was done by generating a
1878            (winter) pickup to start from, switching back the main experiment dynamic
1879            solver from evp to lsr, having one of the experiments use the free drift solution.
1880        part 2: seaice_growth.F revisions 1.76 to 1.85
1881          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
1882          - Sorting out the various fields units and sign (set early on and reset at the end)
1883            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
1884            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
1885          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
1886            and simplifying logical expressions to further improve readibility.
1887        part 3: seaice_growth.F revisions 1.86 to 1.89
1888          - Re-organize the blocks of code more logically.
1889          - Merging the '_if.F' pieces that add something new.
1890    o pkg/thsice:
1891      - vectorize thsice_solve4temp and thsice_get_exf.
1892        Problem: thsice_solve4temp has an unvectorizable statement that
1893        might also be problematic for TAF
1894      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
1895        does not change the verifcation experiment, but will change all
1896        experiments that have this flag undefined (not tested in verification);
1897        a little reorganization to save a few 2D fields and recomputations
1898      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
1899      - 2nd step:  fix some store dirs
1900        o seems to work somewhat, i.e. using ifort but not g77
1901        o likely cause are incomplete init. or recomputation
1902        o start verification/global_ocean.cs32x15/input_ad.thsice
1903    o pkg/obcs: add support for exch2
1904      - the position of the boundary and prescribed values are specified using
1905        a global domain with exch2 facets stacked
1906        - in x for N,S boundaries (like W2_mapIO=-1)
1907        - in y for E,W boundaries (so E,W boundaries do not overlap)
1908    o pkg/mdsio: add support for writing global sections with exch2
1909        file layout is as for obcs described above:
1910        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
1911        - for y-z sections, facets are stacked in y
1912    o pkg/thsice:
1913       - change a few routines for better vectorization: thsice_albedo.F,
1914         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
1915         not affected, but in particular the latter routine has changed
1916         dramatically (not necessarily easier to read now).
1917       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
1918       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
1919    o verification/lab_sea:
1920      - overhaul of the forward model experiments. The main motivation
1921        for this revision is that lab_sea has proven quite fragile (when
1922        changing the sea-ice code, and switching platforms) to a point
1923        when failures were very hard to attribute to specific code problems.
1924      - the suspected reason for this fragility is noise amplification by evp so,
1925        to start with, we decided to replace evp with lsr in the main experiment.
1926      - the input.lsr experiment thus became obsolete and was removed.
1927      - it was replaced with the input.fd experiment that uses an
1928        analytical "free drift" solution as the ice velocity field.
1929      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
1930        will hopefully allow us to discriminate problems due to dynamic solvers
1931        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
1932        us to test additional options, along with the salt plume package.
1933      - Finally a pickup was generated (at the end of a one year run) to
1934        make the tests more representative of an actual model run. Previously
1935        the tests starting point was a 1m thickness of ice everywhere.
1936    o pkg/seaice:
1937      - introducing S\R seaice_freedrift.F that compute the
1938        analytical solution to an approximate ice momentum
1939        equation (i.e. the simple stress/coriolis balance).
1940      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
1941        of the free drift velocity field, and enable its use.
1942        To actually use the free drift solution as the model ice
1943        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
1944    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
1945    
1946    checkpoint62l (2010/10/04)
1947    o pkg/seaice:
1948      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
1949      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
1950       version (with USE_ORIGINAL_SBI undef);
1951    o add hooks for new packages OASIS, the package will follow
1952      (hooks exclude the seaice pkg for now)
1953    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
1954      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
1955      rather than mdsio_readvector.F/mdsio_writevector.F, within
1956      adread_adwrite.F to read/write adjoint-related tapes to disk.
1957    o eesupp and pkg/mdsio: ALLOW_WHIO
1958      Option to write/read 2D fields to files including tiles halos.
1959      The main purpose is for adjoint related "tape I/O".
1960      The secondary purpose is for debugging phases.
1961      A word on those rather specifically intended purposes.
1962      The code was meant to be stripped down to the bare minimum.
1963      Typically, there is a unique and basic mapping to the global
1964      buffer (tile by tile, then proc by proc, then level by level), and
1965      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
1966      meant to generate user friendly outputs of various shapes and forms.
1967      Rather it is intended, for the knowledgeabale developers,
1968      to be largely independent of the many mdsio options, to allow
1969      outputs of tiles+halos in debugging phases and in adjoint runs,
1970      and to allow some flexibility in tuning (adoint) I/O depending on each
1971      file system behavior. With regard to tuning, most of the potential knobs
1972      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
1973      to specify directories, to specify the typical size of I/O calls, etc.)
1974      are not yet included, and will be added if they prove useful.
1975    o pkg/seaice:
1976       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
1977    o pkg/seaice:
1978       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
1979       code (seaice_budget_ice_if.F) which enable to recover old standard
1980       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
1981       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
1982    o model/src (rStar):
1983       use simple average (not area weighted) of rStarFac at U,V point when using
1984       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
1985       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
1986    
1987    checkpoint62k (2010/09/17)
1988    o adjoint
1989       * changed verification/global_ocean.cs32x15 ; adjoint now tests
1990         Adams-Bashforth 3 + NLFS + RSTAR
1991       * some more modifs required for ECCO-GODAE v4
1992    o pkg/seaice
1993       add SEAICE_AGE_VOL option to use volume instead of area for
1994       integrating SEAICE_AGE
1995    o model/src:
1996       first check-in of sigma & hybrid-sigma coordinate code ; also includes
1997       non-linear free-surface parts ; but pressure-gradient not yet coded.
1998    o pkg/ptracers:
1999       option for ptracer to convert Salt Relax into additional EmP.
2000        tested in exp. global_ocean.90x40x15.dwnslp (update output)
2001    
2002    checkpoint62j (2010/08/25)
2003    o pkg/ggl90:
2004       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
2005    o pkg/dic: car_flux.F, phos_flux.F
2006      - reduce number of exp-calls in order to improve performance
2007      - clean up a little (replace fields by their macros, etc., fix
2008        typo in CPP-flag)
2009    o pkg/ggl90: minor changes
2010      - GGL90diffKrS was removed --> always use GGL90diffKr
2011      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
2012      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
2013        (commented out for now)
2014      - change in max/min operations to ensure that smoothing is ok
2015      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
2016      - always use diffKrNrT as background profile (i.e. never use diffKr field)
2017    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
2018    o pkg/dic:
2019      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
2020        vectorization
2021      - small bug fix in insol for the unlikely case of a cartesian grid
2022      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
2023        + now vectorize, which also removes adjoint recomputations;
2024        + replace integer maksp1 by _RL maskp1
2025        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
2026    
2027    checkpoint62i (2010/07/21)
2028    o pkg/flt:
2029      - with OBCS: stop floats which enter the OB region
2030    o model/src:
2031      - use tempVertAdvScheme & saltVertAdvScheme (instead of horizontal ones)
2032        for implicit vertical advection.
2033    o pkg/seaice:
2034     - account for melting in seaice age evolution.
2035     - remove double counting of seaice ridging effect on seaice age.
2036    
2037    checkpoint62h (2010/06/18)
2038    o pkg/exch2:
2039     - remove exch2_*xy_rx files: call was replaced with exch2_*3d_rx(myNz=1).
2040    o tools/genmake2
2041      - remove "-pdefault" option: redundant with the use of "packages.conf";
2042      - remove file pkg/pkg_default : set the default as a pkg group
2043        ("default_pkg_list") defined in pkg/pkg_groups;
2044      - fix for case pkg/pkg_depend is missing (was hanging before);
2045      - add option "-pgroups" to specify a different pkg_groups than the default.
2046    o verification/adjustment.cs-32x32x1:
2047       add a "minimal" set-up test (code_min & input_min) which only compiles
2048       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
2049    o tools/genmake2
2050      - extend pkg_depend rules to model & eesupp (e.g., if model depend on [pkg]))
2051      - fix details of checking for mnc & profile pkg when NetCDF is unavailable.
2052    o pkg/exf: merge exf_bulk_largeyeager04 into exf_bulkformulae because these
2053      files are nearly the same anyway.
2054      Step 1: make exf_bulkformulae look like exf_bulk_largeyeager04:
2055       - redefinition of tau(i,i) (by a factor of ustar)
2056       - 1./exf(Const/T) -> exf(-Const/T) (big change in the results)
2057       - replace rhonil by rhoConstFresh in computation of evap (bug fix)
2058       - replace u/vstress=tau*rd*ws*cw by tau*rd*u/vwind (changes results)
2059       - replace
2060         rd(i,j)= rdn(i,j)/(exf_one - rdn(i,j)/karman*psimh )
2061         shn    = sh(i,j,bi,bj)*rd(i,j)/rdn(i,j)
2062         by
2063         shn    = sh(i,j,bi,bj)/(exf_one - rdn(i,j)/karman*psimh )
2064         (changes results)
2065       -> exf_bulkformulae v1.22,
2066          update verification experiments lab_sea, offline_exf_seaice, seaice_obcs
2067          (lab_sea: output.hb87.txt 1.11, output.lsr.txt 1.25, output.salt_plume.txt 1.13,
2068                    output.txt 1.63
2069           offline_exf_seaice: output.seaicetd.txt 1.7
2070           seaice_obcs: output.txt 1.10)
2071      Step 2: do the actual merge and remove exf_bulk_largeyeager04.F
2072       -> exf_bulkformulae v1.23,
2073          unfortunately requires updating lab_sea.salt_plume (6 matching digits),
2074          and global_ocean.cs32x15.icedyn (only 11 matching digits)
2075      Also update output_adm of exp. lab_sea (all 4) and offline_exf_seaice.
2076    o adjoint of exch-1:
2077     - pass high-level EXCH S/R through TAF (eesupp/src/exch_ad_diff.list)
2078       (note: was already like this when using EXCH-2) and remove flow dir
2079       and hand-written AD version of high-level EXCH S/R (pkg/autodiff);
2080     - provide flow-dir for low-level exch1 S/R (eesupp/src/exch1_ad.flow);
2081     - update pkg/exch2 diff list.
2082    
2083    checkpoint62g (2010/05/19)
2084    o eesupp/src (exch-1):
2085     - split exch_rx.F into Forward S/R (exch1_rx.F) and Adjoint S/R (exch1_rx_ad.F)
2086       and remove argument "simulationMode"; same thing for all exch_*rx_cube.F
2087       (renamed to exch1_*rx_cube.F).
2088     - change accordingly exch_*_rx.template and AD version in pkg/autodiff
2089       to call new exch1 S/R ; update Makefile and .cvsignore.
2090     - replace call to exch2_xy_rx S/R with exch2_*3d_rx(myNz=1) (will remove
2091       exch2_xy_rx later)
2092      Note: after updating your code, need to run "make clean" in eesupp/src
2093    o test experiment bottom_ctrl_5x5:
2094       new output_adm.txt with fewer grdchk & less monitor output.
2095    o model/src:
2096      remove the call to ini_cori in initialise_varia.F (just keep the usual one
2097       in initialise_fixed.F). More consistent with coriolis & horizontal grid
2098       beeing treated in the same way (ini_grid is not called a 2nd time).
2099    o pkg/exf:
2100      - rewrite exf_bulk_largeyeager04.F for better vectorization, changes
2101      global_ocean.cs32x15/input.icedyn (11 digits of agreement), updated
2102      - fix adjoint (used worked for ALLOW_ATM_WIND defined, works for this now)
2103      - cosmetic changes to exf_bulkformulae.F to make it look more like
2104        exf_bulk_largeyeager04.F
2105    o eesupp/src (exch-1):
2106      - Fix AD EXCH code for 2-D domain special cases (Nx=1 or Ny=1).
2107      - Separate buffer filling and MPI sending: allow EXCH-1 to work for local
2108        array (non-shared) when using MPI+MTH. Also reduces number of BARRIER
2109        (even without using MPI).
2110      - Message mode: move RecvAck setting (indicator of buffer being ready)
2111        from send_put to recv_get S/R (was useless before, but not sure if
2112        it's much more useful now);
2113      - Switch the order of sync: MPI-proc 1rst and then threads;
2114      - take out spin-waiting code (#undef EXCH_USE_SPINNING), use BARRIER instead.
2115      - fix AD code for communication mode ='get' (but not used).
2116    o model/src:
2117      initialise dPhiHydX,dPhiHydY inside calc_grad_phi_hyd.F (so that TAF does
2118      not drop it in S/R mddynamics, producing NaN in hs94.1x64x5 AD-test exp).
2119    o utils/matlab/rdmnc.m: adapt to be able to use the generic matlab netcdf API
2120    o pkg/ctrl: require a specific set of control variables and exf-flags for
2121      adjoint of seaice (stop in ctrl_check.F if conditions are not satisfied)
2122    o model/src:
2123     a) 1rst version of a new driver S/R to turn-off output freq and flags after the
2124       1rst forward sweep, to avoid over-writing output files during recomputations
2125       recomputations (& grdchk); called from cost_final.F (& ctrl_init_ctrlvar.F ?)
2126     b) 2nd version:
2127      - add specific pkg S/R for seaice & ptracers (called from S/R TURNOFF_MODEL_IO);
2128      - switch-off more output flags (exf_monFreq, chkPtFreq, dumpInitAndLast,
2129         writePickupAtEnd) + seaice & ptracers output;
2130      - do not switch off MNC flags (otherwise, won't get admonitor netcdf file)
2131    o model/src:
2132      - new S/R rotate_uv2en_rl (..._rs) that rotates vector fields.
2133    o pkg/exch2:
2134      - remove "simulationMode" from arg. list of S/R EXCH2_RX1,2_CUBE ;
2135      - add argument "signOption" to EXCH2_RX1_CUBE (will be needed for SM exch).
2136    o pkg/autodiff & exch2:
2137      process exch_uv_agrid_3d_rx.f & exch2_uv_agrid_3d_rx.f through TAF
2138      (for now, only if ALLOW_EXCH2 is defined).
2139    o pkg/autodiff:
2140      - include PACKAGES_CONFIG.h in exch*ad.flow & exch*ad.F
2141        (not supposed to be in CPP_OPTIONS.h) to get ALLOW_EXCH2 defined correctly.
2142       + clean-up comments (_RS is not always real*4)
2143      - fix bug in ADEXCH_UV_3D_RX (without EXCH2, was calling the forward exch S/R)
2144      - add a stop in ADEXCH_UV_AGRID_3D_RX if trying to use it with EXCH2:
2145        was calling a forward exch2, which is wrong ; used in SEAICE & EXF pkgs.
2146    o testreport (AD-tests):
2147      no longer link files from dir "../input" (1rst link files from
2148      "../input_ad.[xx]" if secondary test "xx" and then from "../input_ad")
2149    
2150    checkpoint62f (2010/04/29)
2151    o model/src/the_main_loop.F:
2152      adjust store directives for seaice evp and multicategory according to
2153      pkg/ecco/the_main_loop.F
2154    o adjoint:
2155      global_sum_ad was incomplete (noted many times by many people ;)
2156      nice description by Jean U. as follows:
2157      * allreduce(var) in global_sum.F can be interpreted as
2158        reduce(sum) followed by broadcast of sum.
2159      * The adjoint of that is
2160        sum(adjoint) followed by broadcast(summed adjoint value)
2161        or in other words, allreduce(sum, adjoint vars)
2162      We were missing the sum(adjoint)!
2163      Benign, except(!) for "global" scalars appearing in tile loops (bi,bj)
2164      (noted by J.M. Campin, e.g., in cost_ssh_mean, variable offset).
2165      The fix should produce 16-digit accuracy between
2166      single-CPU multi-tile (e.g. nSx=2, nPx=1) and
2167      multi-CPU single-tile (e.g. nSx=1, nPx-2)
2168      We'll probably change this yet again shortly
2169    o eesupp/src:
2170      - fix global_sum_r4 (wrong from previous modif in Jun 2009; ever used ?)
2171    o pkg/icefront
2172      - ALLOW_SUBGLACIAL_RUNOFF option adds capability for time-evolving
2173        specification of addmass array based on a 2D field, which is added
2174        at bottommost wet level at each horizontal location.
2175    o model/src:
2176     horizontal grid initialisation (other than curvilinear): add code for Exch2 IO
2177     layout; (not always compatible with delX,delY setting; commented out for now).
2178    o pkg/exch2:
2179     change tile to processor setting (case nSy*nPy > 1): allows default model mapping
2180     (myX and myYGlobalLow) to be used for simple (1 facet, no blank tile) config.
2181    
2182    checkpoint62e (2010/04/15)
2183    o pkg/obcs:
2184      - fix wrong index in OBCS_SPONGE_V for Eastern-OB (reported by David Hebert).
2185    o pkg/dic:
2186      -fix bug in fe_chem.F for multi-tile (nSx*nSy > 1) set-up;
2187        (note: not presently tested in any forward verification exp.)
2188       update tutorial_global_oce_biogeo AD output file.
2189    o pkg/exf:
2190      - account for the variation of albedo as a function of zenith angle
2191        by defining ALLOW_ZENITHANGLE in EXF_OPTIONS.h
2192    o build_options:
2193     - rename "linux_ia64_ifort+mpi_ice_nas" to "linux_amd64_ifort+mpi_ice_nas"
2194    o pkg/dic:
2195      change DIC atmos-CO2 box (method 3, dic_int1=3) initialisation & restart:
2196      - use binary pickup file for restart;
2197      - initialise atmos-CO2 box from dic_pCO2 parameter;
2198      - fix multi-threaded.
2199    o pkg/rbcs:
2200     - clean-up RBCS code: add RBCS_OPTIONS.h file ; fix multi-threaded ;
2201       change (+ fix IO calls) type of array RBC_mask from _RL to _RS.
2202     - add RBCS to exp4 passive tracer 01 (rbcs was previously untested)
2203       and update output.txt
2204    o pkg/kpp:
2205     - add diagnostics for KPP non-local flux of Temp, Salinity and pTracers;
2206     - change diagnostic of KPP non-local term: output average of KPPghat*KPPdiffKzS
2207       (= ratio of KPP non-local (salt) flux relative to surface-flux) when
2208       using pkg/timeave & pkg/diagnostics (diag 'KPPghatK' replaces 'KPPghat ');
2209     - change pkg/offline to read-in average KPPghat*KPPdiffKzS from file
2210       KPP_ghatKFile (instead of the average of KPPghat from file KPP_ghatFile).
2211    o pkg/offline:
2212      fix bug in S/R OFFLINE_FIELDS_LOAD regarding surfaceForcing conversion factor
2213      (bug was added in version 1.10 on 2007-08-23).
2214    o pkg/offline:
2215      - no need to specify periodicExternalForcing, etc ... to use offline pack
2216      - offline input files no longer just single prec --> parameter offlineLoadPrec
2217    o verification/lab_sea:
2218      change AD test to multi-tile setup and update all 4 AD output.
2219      NOTE: while cost function values remain very similar,
2220      gradients are very different, although gradient checks are self-consistent
2221      Should try to get to the bottom of this (cost function summation order?)
2222    o pkg/dic:
2223      in carbon_chem.F, replace log10 (AUTODIFF) with explicit form to avoid
2224      a weakness of TAF that drops part of double precision in log10 derivative.
2225      <= changes removed since problem has been fixed in current TAF version 1.9.71
2226      update AD output of exp. tutorial_dic_adjoffline & tutorial_global_oce_biogeo.
2227    o pkg/ecco:
2228      add missing "_d 0" in cost_readers.F, cost_readtopex.F & cost_readtopexmean.F
2229      update all 4 lab_sea AD output.
2230    
2231    checkpoint62d (2010/03/22)
2232    o build_options:
2233      remove '-r8' (and '-i4') from linux_*pgf and linux_*ifort optfiles.
2234    o remove unbalanced quote (single or double) in commented line of source code
2235      (may cause some warning with some preprocessor/makedepend versions).
2236    o pkg/seaice:
2237      fix seaice_model.F for adjoint (gael) and update AD results of experiments
2238       lab_sea (std + evp + noseaicedyn) and offline_exf_seaice.
2239    o testreport:
2240      add option '-runonly' (short: '-ro') to just do the run part (without make).
2241    o eesupp: remove JAM communication code (obsolete).
2242    o add option to genmake2 & testreport to switch "_RS" type to "real*4"
2243      (if allowed in CPP_EEOPTIONS.h); update default CPP_EEOPTIONS.h and return
2244      to default CPP_EEOPTIONS.h for exp. inverted_barometer & solid-body.cs-32x32x1
2245      (update also the output).
2246    
2247    checkpoint62c (2010/03/02)
2248    o tools/build_options :
2249       move (some) old optfiles from build_options/ to build_options/unsupported/
2250    o model/src and pkg/exf
2251       surface relaxation -- separating data and data.exf options
2252       The point is to ensure that we specify the surface relaxation
2253       either in data or in data.exf (but not half and half) and to
2254       avoid an accidental relaxation to 0 (which happened if a time
2255       scale was specified but the file name was left empty)
2256    o model/src model/inc and pkg/mom_common
2257       ALLOW_3D_VISCAH/ALLOW_3D_VISCA4 => 3D specification of Viscosity
2258       => addition to the viscosity field as computed by others schemes
2259    o tools/build_options:
2260      - rename "_generic_mpi" -> "+mpi_generic" (like other "+mpi" optfile)
2261        but keep the former optfile for few weeks for smooth transition
2262    o pkg/ecco
2263      - allow user defined cost function contributions
2264         CPP: ALLOW_USERCOST_CONTRIBUTION
2265         USAGE: compute contributions in cost_usercost_all.F
2266      - note: this is identical to what ALLOW_GENCOST_CONTRIBUTION once was.
2267          the two options are complementary.
2268    o pkg/smooth
2269      - migration from contrib to the main repository
2270    
2271    checkpoint62b (2010/01/26)
2272    o pkg/monitor:
2273      - change back mon_printstats_rl.F & mon_stats_rl.F and add a stop
2274        (in case someone forgot to update customized pieces of code)
2275    o nonHydrostatic:
2276      - add Non-hydrostatic free-surface form (selectNHfreeSurf=1)(not fully tested);
2277      - add a simple 2-D experiment (short_surf_wave) to test it.
2278    o pkg/icefront:
2279       adding the shell of, and the hooks to, a new package that
2280       will model melting and freezing of vertical glacier ice fronts
2281    o momentum:
2282      add diagnostics of momentum tendency from Hydrostatic pressure gradient
2283       (without surf.pressure term: would need a 2nd filling since implicit term).
2284    o add 3 "_d 0"s so that fizhi compiles with xlf on iblade, and replace
2285      two " &end" by " &" (in fizhi-cs-*) because S/R NML_SET_TERMINATOR
2286      cannot deal with the former
2287    o cleaning:
2288      - remove all (except OpenAD) old TLM output from results_ad dirs.
2289      - remove unused S/R (MDSWRITEMETA, DIAGNOSTICS_ADD2LIST, old DFILE IO S/R)
2290      - comment out maskH definition (replaced by maskInC)
2291    o pkg/monitor:
2292      - change mon_printstats_rl.F & mon_stats_rl.F (were similar to mon_writestats_rl
2293        & mon_calc_stats_rl) to be the RL equivalent of mon_printstats_rs & mon_stats_rs.
2294    
2295    checkpoint62a (2010/01/15)
2296    o model/src:
2297      - bottom pressure diagnostic: correct for r* (when nonlinFreeSurf >= 4)
2298    o pkg/diagnostics:
2299      - add optional level number diagnostics (i.e., level number to be define
2300        explictly with S/R DIAGNOSTICS_SETKLEV) with parser-code(10)="X".
2301      - strictly check for valid parser-code(10) ;
2302      - check if adding diag to the list from the right place.
2303    o pkg/longstep:
2304      - change parameters and fix tracer conservation with rstar/nonlinear free surface
2305    o diagnostics:
2306     - in all pkgs, replace remaining calls to old S/R DIAGNOSTICS_ADD2LIST with newer
2307       S/R DIAGNOSTICS_ADDTOLIST ; fix seaice VICE diagnostics.
2308    o pkg/diagnostics:
2309     - Add option for writing vertical integral (sum of selected levels) of an output
2310        field instead of writing output field levels. Activate this option on a per
2311        output-file basis, by setting the 2nd character of fileflag to 'I'.
2312     - Add field-specific information relative to level integral in 3rd postion
2313        of parser diagnostics code (gdiag): " "=cumulate levels, "R"=integrate
2314        vertically (x level-thickness x hFac), "r"=same but without hFac.
2315    o do_the_model_io:
2316      - pass end-of-model-run flag as argument, from forward_step to diagnostics_write:
2317        in case useSIGREG, will write (averaged) diagnostics (if dumpAtLast) before
2318        writing pickups and stopping.
2319    o pkg/diagnostics (for now, only with mdsio):
2320      - write time information to meta file (and modify accordingly rdmds.m) :
2321        time-averaged diagnostics output: write starting and ending time of the
2322        time-averaging interval ; snap-shot diagnostics output remains unchanged;
2323    o pkg/timeave:
2324      - S/R TIMEAVE_NORMALIZ: change size of cumulated-time array (was previously
2325        always Nr), now assumed to be equal to number of levels of averaged field;
2326        only used for DIC_COST monthly mean arrays: this fixes dic_aver_final.F
2327    o pkg/sbo:
2328      - fix ocean bottom pressure global-average & 2-D time-ave output (was
2329        neither initialised nor filled).
2330      - add starting iteration in suffix of global-average output file
2331        (to avoid over-writing the file after a restart)
2332      - use standard MDSIO pkg S/R instead of SBO_WRITEVECTOR (fix byte-swap Pb).
2333    o time-average:
2334      - use simple cumulative-time array (no k index) in all pkgs: {PKG}_timeAve(bi,bj)
2335        (pkgs: aim_v23, bulk_force, dic, gmredi, kpp, land, ocn_compon_interf,
2336         ggl90, my82, opps, pp81, ptracers, sbo, seaice, shelfice, thsice)
2337        this fix DIC_COST cumulative-time array (previously: bi,bj,k)
2338      - fix 1rst call (nIter0) snap-shot output and accumulation (pkg/shelfice)
2339      - fix missing accumulation for pkg/opps.
2340      - cumulate fields only if doing time-ave output ({PKG}_taveFreq > 0)
2341         (pkgs: ptracers, kpp, ocn_compon_interf, ggl90, my82, pp81);
2342      - fix initialisation of time-ave vars and do only full time-step increment
2343        (i.e.: no first & last "half time-step") (pkgs: ggl90, my82, opps, pp81);
2344    o pkg/layers:
2345      - use standard RW pkg S/R to write the output
2346        and remove local write_fld version (which had a problem).
2347      - use simple cumulative-time array (no level index) to fix time-ave S/R calls.
2348      - fix LAYERS_CALC argument list.
2349    o pkg/timeave:
2350      - store cumulative-time in a simple tiled array (drop the level index)
2351      - add new S/R (TIMEAVE_NORMALIZE) which uses simple cumulative-time array.
2352    o pkg/ocn,aim_compon_interf
2353      - changes for multi-threaded coupled run. (tested with ifort-11 on danton)
2354    
2355    checkpoint62  (2009/12/23)
2356    o switch on useOBCSbalance in tutorial_plume_on_slope exp. and update output.
2357        (was not previously tested in any other exp.)
2358    o pkg/monitor:
2359      - clean-up _RL/_RS version: add specific S/R for statistics with mask & volume:
2360        mon_writestats_rl/s,F mon_calc_stats_rl/s.F ; will keep the old one
2361        (mon_printstats_rl/s,F mon_stats_rl/s.F) just for bare statistics.
2362      - use hFac & 2-D mask (instead of 3-D mask + hFac in previous mon_stats_rl.F).
2363      - change del2 calculation.
2364      - use interior masks (instead of maskH, <- to be remove).
2365      - shorter monitor suffix for forcing stats ("forcing" instead of "extforcing").
2366    o mask & obcs:
2367      - define 2-D "interior" masks (i.e., zero beyond OB) at 3 locations (C, W & S).
2368      - move global area computation from ini_masks_etc.F to ini_linear_phisurf.F
2369        (called after packages_init_fixed)
2370    o pkg/obcs:
2371      - move bi,bj loops into obcs_calc, so obcs_prescribe_read is called only once.
2372        Fixes bug in obcs+exf with nSx*nSy.GT.1
2373      - fix multi-tile handling in obcs balance code
2374    o nonHydrostatic:
2375      - Implement AB-3 for non-hydrostatic vertical momentum ;
2376        (change ordering of var. stored in pickup file when using NH)
2377      - move NH code from solve_for_pressure.F to 2 new S/R: PRE_CG3D & POST_CG3D.
2378      - add 2-D field to store Hydrostatic Surface Pressure adjusment from cg3d_x
2379        (in prep. for new NH free surface form).
2380    o pkg/obcs:
2381      add files & OB-variables for wVel (Non-Hydrostatic) with useOBCSprescribe
2382    o model/src:
2383      fix 2-D solver initialisation for deep-atmosphere (p-coord) with topography
2384    
2385    checkpoint61z (2009/12/01)
2386    o nonHydrostatic:
2387      Fix missing vertical flux of vert. momentum near surface (k=1). This fixes
2388        a spurious source of energy in simple baroclinic adjusment test case.
2389      Update all non-hydrostatic exp output.
2390    o model/src (3-d solver):
2391      Change again 3-D solver free-surface RHS term when exactConserv=T:
2392        simpler, consistent with exactConserv, and works with implicDiv2Dflow < 1
2393        (which was not the case with previous formulation).
2394      To recover previous version, just reset "oldFreeSurfTerm" to previous value.
2395      Affects results of exp. global_ocean.cs32x15.viscA4 & hs94.cs-32x32x5.impIGW.
2396    o nonHydrostatic:
2397      - compatible with implicDiv2Dflow < 1 ; + implement implicit factor
2398        for Non-Hydrostatic pressure gradient (similar to implicSurfPress).
2399      - change 3-D solver to work with r* (for now, only with linear free-surf.)
2400      - add few debug diagnostics (cg3d_x, residual)
2401    o model/src:
2402      fix missing EmPmR in 3-D solver RHS (was in cg2d_b but missing in cg3d_b).
2403        update output of exp. global_ocean.cs32x15.viscA4
2404    o update output of exp. global_ocean.cs32x15.icedyn after removing
2405      #define SEAICE_OLD_AND_BAD_DISCRETIZATION from SEAICE_OPTIONS.h
