7    checkpoint63o (2012/06/29)
8    o vertical mixing schemes:
9      - remove unused S/R CALC_BUOYANCY (left from branch-atmos merging)
10      - replace computation of density (in Function STATE1, opps_calc.F) by a call
11        to S/R FIND_RHO_SCALAR
12      - pass sigmaR to S/R PP81_CALC, MY82_CALC (but not yet used) and to GGL90_CALC
13        and use it for N^2 calculation in ggl90_calc.F (save 2 density computations);
14        affects output (vermix.ggl90) at truncation level.
15    o testreport:
16      - change adjustment of SIZE.h for mpi+mth testing: preserve enough tiles
17        (nSx,nSy) for the number of threads (from eedata.mth)
18    o model/src:
19      - remove 2nd set of calls at the top of initialise_varia.F (Adjoint part)
20        related to Non_Lin Free-Surf or Bottom-Control (but not longer necessary).
21    o verification/tutorial_tracer_adjsens/
22      - compile with ALLOW_CG2D_NSA
23      - run with nonlinFreeSurf=3
24      - update reference output_adm.txt
25    o tools/genmake2:
26      - add "-DHAVE_NETCDF" to the DEFINES list when NetCDF is available ;
27        refine usePROFILES switching off (only when NetCDF is not available).
28    o verification (atmospheric set-up):
29      - change eosType='IDEALGAS' to eosType='IDEALG' to match variable declaration
30    o pkg/profiles : refine profiles and files handling.
31    o model/src and pkg/ecco : introduce run-time switch usePROFILES.
32    o model/src/the_main_loop.F, forward_step.F and pkg/exf/EXF_OPTIONS.h :
33      - changes to use model/src/the_main_loop.F rather than the ecco version
34        in ecco type adjoint runs.
35    o model/src:
36      - move computation of recip of grid distance & area from INI_MASKS_ETC to INI_GRID
37      - move setting of h0Fac[C,W,S] from INI_LINEAR_PHISURF to INI_MASKS_ETC
38      - update_masks_etc.F: rename SMOOTH*_R4,R8 function to the corresponding type (RS,RL)
39    o model/src:
40      - fix S/R UPDATE_CG2D for ALLOW_DEPTH_CONTROL case (was empty before);
41        update output of test experiment bottom_ctrl_5x5.
42    o pkg/generic_advdiff:
43      - implement vertical bi-harmonic diffusion (for now, only for T & S and
44        only explicitly).
45    o verification/bottom_ctrl_5x5/
46      update reference output (results changed quite some time ago,
47      not sure when; but new reference results look ok in terms of grdchk)
48    o verification/1D_ocean_ice_column/
49      For verification purposes, the exact adjoint rather than an approx.
50      should be used (e.g., to comare against F.D. or TLM).
51      removed autodiff_inadmode*_ad.F routines in code_ad/
52      Update results/ accordingly.
53    o pkg/cal:
54      - change cal_getdate.F so that output date is function of input time only
55        (less ambiguous, not mixed up with input iteration number).
56      - fix calendarDumps for non-zero phase-lag (S/R CAL_TIME2DUMP).
57    o pkg/diagnostics:
58      - implement calendarDumps also for stats-diags
59      - implement calendarDumps also for snap-shot output (negative freq)
60      - for now, ignores calendarDumps if non-zero phase-lag.
61    
62    checkpoint63n (2012/06/04)
63    o model/src:
64      - recompute rSurfW & S to ensure consistent column thickness (needed for rStar)
65        between Sum_k(hFac*drF) and rSurf-rLow, for now only when using pkg/shelfice;
66      - use h0FacC, W & S to compute hFac_surfC, W & S in calc_surf_dr.F (more
67        similar to calc_r_star.F); update results of experiment internal_wave and
68        tutorial_global_oce_in_p (affected @ truncation level).
69    o pkg/shelfice:
70      - add parameterisation of advective-diffusive flux into the ice shelf
71        according to Holland and Jenkins (1999), eq.22-33, as suggested by Jan De Ryd
72      - simply eps3/3a computation
73    o eesupp:
74     - add new CPP option (DISCONNECTED_TILES) to disconnect tiles (no exchange
75       between tiles, just fill-in edges assuming locally periodic subdomain) and
76       add corresponding exchange subroutines (EXCH0);
77     - new CG-solver version (_EX0) for disconnected-tiles special case.
78    o model/src (CG-solvers):
79     - modify Single-Reduction version (CG2D_SR) in case cg2dMaxIters is reached
80       (similar final residual output and max-Iter number as with standard version);
81     - allows to store and use lowest-residual solution (standard & _SR versions);
82     - cleaning up (remove old, commented out code, LETS_MAKE_JAM ...).
83     - by default, also compile CG2D_SR version (define ALLOW_SRCG in CPP_OPTIONS.h)
84    o eesup/src:
85     - global_vec_sum.F cleaning: add a BARRIER ; update comments ; remove ndef
86       ALWAYS_USE_MPI (no longer needed after fixing usingMPI settings - March 2012)
87    o pkg/salt_plume added to lab_sea/input_ad.noseaicedyn
88    
89    checkpoint63m (2012/04/27)
90    o pkg/shelfice:
91     - account for partical cells in surface level below ice-shelf for hydrostatic
92       pressure calculion (set uniformFreeSurfLev to F); update isomip experiments.
93    o ad test experiments:
94     - update and rename to "ad_optfile.local" local AD-optfile specific to a
95       particular adjoint verification experiment (in verification/*/code_ad/)
96    o pkg/seaice & pkg/exf:
97     - Part two of ECCO-CLIVAR code merges.
98       Completes merge of seaice area relax. code.
99       Requires unified CPP option EXF_ALLOW_SEAICE_RELAX
100       to be set in EXF_OPTIONS.h since this pkg controls its I/O
101       (and avoids second CPP option in SEAICE_OPTIONS.h)
102     - change default value of costIceStart & costIceEnd to a valid date.
103     - add snowPrecip to HSNOW in seaice_growth
104    o pkg/ptracers:
105     - move ptracers summary and setup check into separated S/R ; add a check for
106       valid PTRACERS_Iter0 value (error+stop or just warning).
107    o pkg/cal (+ pkg/ecco):
108     - avoid calling a S/R with 2 times the same arg (FWD: unless both are only used
109       as input; and for AD, unless both are not differentiable (e.g., k index)).
110    o model/src:
111     - define internal flag "uniformFreeSurfLev" (=T when free-surface level-index
112       is everywhere k=1) to speed-up some calculations (by pass kSurf reference);
113       temporary set to usingZCoords value (to be changed to F when using shelfice).
114     - hydrostatic pressure: implement partial cell near the surface also for
115       Z-coordinates (for the case where uniformFreeSurfLev=F); replace test on
116       usingZCoords with test on uniformFreeSurfLev where needed (in NonHyd code).
117    o pkg/ctrl/ctrl_init.F:
118     - add a formal parameter to s/r ctrl_init_rec to print
119       xx_$(ctrl_valiable)_file for easier debugging
120     - move call of cal_* routines into the if-block where they are really
121       needed so that xx_$(ctrl_variable)_period can be 0 or -12 without having
122       to specify a startdate
123    o pkg/seaice:
124     - update comments in SEAICE_OPTIONS.h (+ similar update of lab_sea/code and
125       global_ocean.cs32x15/code versions).
126     - turn on seaice Multi-category (in data.seaice, SEAICE_multDim=7) for
127       verification experiment global_ocean.cs32x15.seaice and update results.
128    o pkg/exf:
129     - new S/R EXF_GETFIELD_START to return starting-time of a forcing field
130       (according to useExfYearlyFields).
131    o pkg/cal:
132     - move calendar setting & summary (previously in cal_readparams.F) into new
133       S/R CAL_INIT_FIXED to be called later in the initialisation process, once
134       length of the simulation is set (after SET_PARMS call); This is an attempt
135       to fix Pb when, e.g.: pkg/longstep, modifies the length of the run.
136     - For safety: keep a record of pkg/cal parameter settings status
137               to allow to STOP if one pkg/cal S/R is called too early.
138     - add a stop in all basic pkg/cal subroutines if called before setting is done.
139     - modify cal_getdate.F: stop when nothing was returned;
140       if called with myIter=-1, simply retrun modelBaseDate (1,2 = startDate_1,_2);
141       this allows to remove "cal.h" from seaice_read_parms.F & init_mnc_vars.F.
142    
143    checkpoint63l (2012/04/04)
144    o pkg/bbl:
145      - fix call to FIND_RHO_2D in bbl_calc_rho.F (case multi-tiles per proc);
146        update global_with_exf output.yearly.txt file.
147    o pkg/cal:
148      - start to clean-up cal_set.F ; fix for the case where baseTime is non-zero.
149      - remove 2 unsused and very short (1 line only) functions ;
150      - remove unsused subroutines from AD-Diff list.
151    o model/src:
152      - start to implement clean wait to stop in initialization S/R (config_check.F,
153         packages_check.F, ini_parms.F and pkg/obcs/obcs_check.F + pkg/mypackage)
154    o folowing PRINT_MESSAGE changes:
155      - remove reminder multiple print to the same file (STDOUT) when multi-threads.
156    o pkg/bbl:
157      - modification so it can work with z*
158      - replace deltaT with dTtracerLev(k) for asynchronous time stepping
159      - global_with_exf/input.yearly verification; changes output.yearly.txt
160    o eesupp/src:
161      - PRINT_MESSAGE: use OpenMP critical instruction (similar to PRINT_ERROR);
162        writing to unit 0 (if unit=errorMessageUnit) extended to the case myThid=1
163      - CHECK_THREADS: specific code if using OpenMP threading: improve checking of
164        # of threads across processors (e.g., different env OMP_NUM_THREADS setting)
165      - improve special preliminary call to EESET_PARMS (if eedata is read 2 times).
166      - when using MPI, always set usingMPI=T ; set default accordingly and stop
167        if not consistent.
168      - ALL_PROC_DIE: add a BARRIER after MPI_FINALIZE call ; skip this when thread
169        argument is zero (in case called within single-thread section).
170    o pkg/fizhi:
171        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
172        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
173    o pkg/exch2:
174      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
175        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
176      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
177        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
178        with bad ones coming from a not-yet-updated halo.
179        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
180    o pkg/frazil:
181        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
182        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
183    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
184    o verification/lab_sea
185      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
186      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
187      * nTimeSteps 3 -> 4
188      * changed reference output accordingly
189    o pkg/ctrl:
190      * fix ctrl_get_gen for xx_sst, xx_sss
191    o pkg/fizhi:
192      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
193        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
194      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
195        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
196        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
197    o pkg/gmredi:
198      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
199    o pkg/fizhi:
200      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
201        (old)aces open64 tuv test.
202    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
203    o pkg/mom_vecinv:
204      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
205        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
206        with non-lin free-surf).
207    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
208      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
209      some compilers (gfortran 4.6.0 on MacOS)
210    o momentum:
211      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
212        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
213        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
214    
215    checkpoint63k (2012/03/17)
216    o model/src:
217       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
218         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
219       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
220         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
221    o model/src: solve_*diagonal.F
222       - replace division with multiplication by inverse (similar to original version)
223         update output of AD exp. global_ocean.90x40x15.
224       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
225         to enable the use of the vectorized & differentiable solve_tridiagonal.F
226       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
227         vertical advection (to get solve_tridiagonal tested in AD mode).
228    o pkg/seaice: ECCO-CLIVAR merge:
229      1. seaice AREA relaxation
230         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
231         * runtime flag: SEAICE_tauAreaObsRelax
232      2. modified global mean cost imbalance code: CPP option
233          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
234    o another iteration on solve_*diagonal.F
235       Make choices independent of AUTODIFF
236       Default will be the adjoinable vectorized version.
237       Alternative choices are:
238       * non-adjoinable original version with low memory footprint:
239         #define SOLVE_DIAGONAL_LOWMEMORY
240       * still adjoinable but does not vectorize (k as inner-most loop):
241         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
242    o testreport
243     - add option to use a home made wrapper around "make"
244     - remove MITGCM_IEEE env. variable (no longer active)
245    o pkg/shelfice
246     - improve computation of friction velocity for velocity dependent
247       exchange coefficients: include velocities into SHELFICEBoundaryLayer
248       block to average velocities vertically
249     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
250    o Modify diagonal solvers, now three versions (upon request):
251      #ifndef SOLVE_DIAGONAL_AUTODIFF
252        1. default version (dating back a while ago)
253      #else /* def SOLVE_DIAGONAL_AUTODIFF */
254      # ifdef SOLVE_DIAGONAL_KINNER
255        2. adjoinable version with k-innermost loop (G. Forget)
256      # else
257        3. adjoinable vectorized version of 2.
258      # endif
259      #endif /* SOLVE_DIAGONAL_AUTODIFF */
260      All flags are currently set within routines, but could/should be moved to CPP-options.
261      Array bounds for 1. are as before, for 2.,3. cover the entire domain
262      (could be changed for 1. too).
263    o verification/lab_sea (fwd):
264      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
265        use 7 categories (except hb87), new solve4temp params (except salt_plume),
266        constant salinity (=4) or variable salinity (salt_plume) done through
267        SItracer.
268    o pkg/seaice:
269      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
270      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
271         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
272        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
273        SEAICE_freeze got retired) but already better than previously with
274        SEAICE_freeze=123456.7 deg.C;
275      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
276        (safer multi-threaded setting); always set SEAICEuseEVP;
277      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
278        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
279        stop if multiple specifications for the same coeff; make sure default
280        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
281    o pkg/obcs:
282      - allow to switch to upwind 1rst order advection scheme for the advective
283        flux computation at the open-boundary; disabled for adjoint built.
284    o pkg/ptracers:
285      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
286      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
287      - add parameter to decide when to start a tracer; use internal flag to
288        know which tracer to step-forward; switch this internal flag at the top
289        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
290        for adjoint built.
291    o pkg/seaice:
292      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
293      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
294      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
295    o pkg/ecco:
296      - fix writing of output file DiagnosCost_ClimSalt/Theta
297        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
298    o pkg/seaice:
299      - add missing initialisation of COR_ICE array in dynsolver.F
300      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
301        compiled either way, and is tested in all exps (multidim was only tested
302        in lab_sea ad before).
303      - cosmetic change to prepare for future addition of ITD. no change to results.
304        no defaults change.
305      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
306      - by lack of adequate verification experiments, I further used custom versions
307        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
308        should be correct.
309      - avoid recomputations in ad.
310    o array initialisation in adjoint mode:
311      1) pkg/mom_common/mom_calc_ke.F:
312        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
313        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
314        part this initialisation is gone, resulting in Floating Point Exception
315        (caught by open64 compiler with debug option).
316      2) model/src/convective_weights.F
317        set output convectCount over the full array range (instead of doing
318        an update): this fix a similar issue when called within recomputation (adjoint)
319        which could by-pass the initialisation (normally done in the caller S/R).
320    o pkg/seaice:
321      - final version of turbulent flux params, as agreed at MIT ice meet:
322           SEAICE_mcPheePiston (default is ~ 0.000875)
323           SEAICE_mcPheeTaper (default is 0.)
324           SEAICE_frazilFrac (defualt is 1.)
325           SEAICE_mcPheeStepFunc (default is false)
326      - changes results at trunction error level
327      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
328    o added pkg/frazil:
329      - see frazil_description.tex for details
330      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
331    o pkg/shelfice/shelfice_thermodynamics.F
332      - fix exponents for velocity dependent exchange coefficients: change
333        from 2/3(=0) to 0.66666666666666667
334      - move computation of velocity dependent exchange coefficients into
335        separate loop, so that it applies to both thermodynamics
336      - move some divisions by constants out of loops
337    
338    checkpoint63j (2012/02/16)
339    o pkg/seaice:
340      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
341      - SItracer:  added run time params, and allow coupling to ocn salinity.
342    o pkg/seaice: remove (almost) all divisions by constants within loops
343      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
344      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
345      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
346      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
347    o pkg/seaice :
348      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
349        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
350      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
351      - add permanent SItflux diag that corresponds to TFLUX but includes
352        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
353      - allow activation/testing of a fix for suspected missing term in
354        ocn-ice heat budget (to be confirmed). To test this, you want to
355        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
356        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
357      - no change in results, fwd or ad.
358    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
359      - switch to variable freezing point.
360           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
361      - bug fix : the sublimation term that was missing is now activated.
362           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
363      - bug fix : flooding sign term for SIsal0.NE.0.
364           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
365    o pkg/seaice:
366      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
367        is now the default, and the old default constant freezing point is recovered
368        with SEAICE_tempFrz0    = -1.96,
369             SEAICE_dTempFrz_dS = 0.,
370      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
371      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
372      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
373        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
374      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
375        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
376      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
377        seaice_growth r149 for legacy branch (no results change).
378      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
379        from I. Fenty).
380      - results did not change except for global_ocean.cs32x15, mostly due to the
381        switch to variable freezing point (see above item for detail).
382    o pkg/thsice:
383      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
384        seawater freezing in thsice_calc_thickn (not used).
385    o pkg/seaice: turbulent flux term specification via run time params.
386      - replace CPP switches with run time switches to facilitate testing
387      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
388                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
389      - added runtime parameter : SEAICEturbFluxFormula
390      - move Mcphee constants to SEAICE_PARAMS.h
391      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
392                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
393                 remove seaice_summary call (moved to seaice_init_fixed)
394      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
395        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
396      - seaice_summary.F : add missing report of read turbulent flux term set up
397                           and SITRACER.
398      - seaice_check.F : check range; inform and stop if retired CPPs are used
399                         (incl. SEAICE_AGE).
400      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
401             CPP switch, same computation as before for the different options.
402      - change results at the truncation level.
403    o pkg/seaice:
404      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
405        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
406        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
407      - update verification/*/input*/data.seaice:
408        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
409        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
410        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
411        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
412    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
413      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
414        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
415        difference in results only due to machine truncation.
416      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
417        MaykutPolySatVap; keep MIN_LWDOWN.
418      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
419      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
420        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
421    o pkg/salt_plume:
422      - isolate saltPlumeFlux array exch into a specific S/R called from
423        do_oceanic_phys.F
424      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
425    o verification:
426      - move untested set-up to MITgcm_contrib/verification_other.
427    o pkg/seaice:
428      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
429    o pkg/seaice:
430      - seaice_solve4temp.F (keeping results unchanged):
431        * add 2 future run-time params to select which saturation vapor pressure
432          formula is used and how post-iteration fluxes are set.
433          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
434        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
435          the linearized expression to stay consistent with tsurf finding.
436      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
437        can be < 0.
438    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
439      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
440        conductive heat flux F_c , and add it explicitly when updating tsurf as
441        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
442        so that now F_ia has a consistent meaning through the entire routine.
443        This causes differences at truncation level: update output of fwd exp.
444        global_ocean.cs32x15.seaice.
445    o pkg/seaice:
446      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
447        of arrays, sign/direction of fluxes; no effect on results.
448      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
449        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
450        note: this should have been done before changing celsius2K default.
451      - to keep results unchanged, add back old value of celsius2K in verification
452        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
453      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
454        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
455        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
456        freezing temp is consistent with value in seaice_growth.F ; this causes
457        differences at machine truncation level: update lab_sea AD output (3/4).
458    o pkg/seaice:
459      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
460        and climsst/sss even when using seaice (to prevent calculation that might
461        use SST on land); does not affect any verification exp.
462      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
463        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
464    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
465      over land (non-legacy code)
466    o vectorize salt_plume package:
467      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
468      - this code computes plumebk everywhere (also over land), thus requires
469        code to avoid divisions by zero and catch the case of kLev=Nr.
470      - efficiency of salt_plume_frac is still sub-optimal
471    o tools (genmake2):
472      - fix makefile NAME specification (option: -makefile NAME) by adding
473        "-f $MAKEFILE" in few places where it was missing including makedepend
474        command (contribution from Paul).
475    
476    checkpoint63i (2012/01/24)
477    o model/src:
478      - add factorized versions of some EOS code to find_rho.F,
479        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
480    o model/src:
481      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
482      - change default celsius2K from 273.16 to 273.15
483      - to keep results unchanged, add back old value of celsius2K in verification
484        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
485         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
486    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
487      to make TAF generate vectorizable code
488    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
489       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
490       have flags that do this more efficiently.
491    o pkg/diagnostics/diagstats_calc.F
492      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
493    o pkg/obcs (with exch2):
494      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
495        and remove code (in obcs_readparms.F) which was based on EXCH of indices
496        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
497    o pkg/exf and seaice exp:
498      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
499        so that switching off area & heff advection flags does not affect results.
500      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
501      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
502        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
503        results of verification experiments: 1D_ocean_ice_column(fwd),
504        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
505        and offline_exf_seaice (all 4).
506    o pkg/seaice:
507      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
508        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
509      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
510        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
511        not multi-dim advection;
512      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
513        SHORTWAVE_HEATING #undef.
514    o optim: make Makefile more robust (?)
515    o pkg/obcs:
516      * fix treatment of obcs_read_pickup for TAF
517    o pkg/shelfice:
518      * add missing initialisation of num_shifwflx
519      * new adjoint verification exp. for isomip
520      * change Prandtl and Schmidt numbers from generic formulations
521        (in terms of model diffus. and visc.) to separate runtime
522        parameters, with Holland and Jenkins (1999) default values.
523    o pkg/exf (interpolation):
524      - extended input field (2 rows) near the N & S poles:
525        * fill in with the symetric value (when even Nb of data in longitude)
526        * add average value at the poles only for scalar quantities ; for vector
527          component interpolation, skip the averaging and keep duplicated values,
528          unless the 2 components have same location (uvInterp=T) in which case
529          interpolate the 2 components together using S/R EXF_INTERP_UV.
530      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
531        together: this allows to account properly for local orientation when
532        averaging at N & S pole.
533      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
534        exf-interpolation near N & S poles. Undef by default.
535      - add debug check/print on 1rst iter if debugLevel >=2.
536    o pkg/exf:
537      - change masking flags definition (no longer "parameter"), put them in
538        common block and set them in S/R EXF_INIT_FIXED.
539      - change recognized masking flag from s,u,v to c,w,s since the mask
540        to use (maskC,W,S) depends on position on model grid and has little to
541        do with scalar/vector difference; fix masking if using P-coordinates.
542      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
543        and update results of exp. global_with_exf (x2).
544      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
545    o pkg/obcs
546      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
547    o pkg/exf (interpolation):
548      - assume periodicity in X only if input field cover full longitude range.
549      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
550        and should vectorise).
551      - fix input lat of the 2 added row (in case we provide N.pole data).
552    
553    checkpoint63h (2011/12/30)
554    o pkg/seaice:
555      - change declaration of UVM from _RL to _RS in order to get B-grid
556        uIce,vIce monitor when _RS = real*4
557    o pkg/offline:
558      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
559      - compute vertical velocity if not read from file (switch on exactConserv
560        & staggerTimeStep);
561      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
562    o verification:
563      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
564        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
565        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
566      - update output of exp. global_ocean.cs32x15.viscA4 after changing
567        grid-file angles (used here for coriolis-3d);
568      - remove (or gzip) few files not needed to run fizhi-cs experiments.
569    o pkg/exf (vector interpolation):
570      - rotate vector component toward local grid-axis orientation using grid-angles
571        (stored in GRID.h) instead of locally computed rotation angle; keep old code
572        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
573    o pkg/seaice:
574      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
575        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
576    o pkg/PKG_OPTIONS.h files:
577      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
578        outside of the #ifdef ALLOW_THISPKG / #endif block.
579      - update verification/*/code/PKG_OPTIONS.h files.
580    o add a verification experiment (offline_exf_seaice/input.seaice) that test
581      the B-grid LSOR solver
582    o pkg/seaice: sort out emissivity and long wave radiation step 2:
583      - add emissivity for snow and ice as new run-time parameters
584        (unfortunately) that default to the corresponding exf values; this
585        changes results in most verification experiments so that for backward
586        compatibility these parameter have to be set explicitly to inconsistent
587        values (ugly);
588      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
589        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
590        until we agree how to handle this bug properly
591    o pkg/exf (interpolation):
592      - add a set of run-time param ({inputfield}_interpMethod), one for
593        each interpolated input field, to select the interpolation method
594        with a value of zero switching off the interpolation;
595      - print interpolation parameters to standard output;
596      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
597        (to use instead runoff_interpMethod=0 in data.exf).
598      - simplify default setting of interpolation parameters (for all fields,
599        set position to match model grid cell-center position, leading to trivial
600        interpolation in case of regular Lat-Lon grid) and fix for the case of
601        non-uniform delY.
602    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
603       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
604       this factor is absolutely required, because the lw exitance (= out-going
605       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
606       where the reflectivity rho = 1-emissivity for conservation reasons. Once
607       this is established, we can remove the CPP-Flag (if we want to).
608    o pkg/seaice:
609      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
610        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
611      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
612        what the name implies (and not emissivity*BoltzmannConstant), this means
613        the old default value of 5.5e-8 now means
614        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
615        S/R exf_readparms
616      - FV-discretization of the B-grid LSOR solver, turn on with
617        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
618        of the calling routine dynsolver, so that B and C-grid code look a
619        little more alike.
620      - fix index bugs in ostres.F (B-grid code)
621    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
622    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
623      default for SEAICE_emissivity, if useEXF; requires setting a wrong
624      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
625      backward compatiblity
626    o model/src: use sigmaR in calc_ivdc
627    
628    checkpoint63g (2011/12/16)
629    o pkg/seaice/seaice_growth.F:
630      fix heat conservation of the coupled ocean-seaice system.
631      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
632      solid vs liquid water treatment is resolved via QNET.
633    o pkg/seaice/seaice_growth.F:
634      add missing term for sublimation in saltFlux, which was breaking conservation.
635    o pkg/seaice/seaice_model.F:
636      Remove this patholigical case treatment in evolution branch,
637      where it is un-necessary and breaks conservation.
638      Update global_ocean.cs32x15/results accordingly for
639      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
640    o model/src:
641      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
642      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
643    o pkg/obcs:
644      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
645      tendency for temperature and salinity that is then applied to update
646      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
647      horizontal advection and diffusion contributions on the boundary (in
648      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
649      removing the mask in S/R timestep_tracer. The advantage of this approach is
650      that the updated tracer values include contributions from the surface
651      forcing and vertical diffusion.
652      This modification changes exp4.stevens because of vertical diffusion.
653    o model/src:
654      change non-curvilinear grid setting to also work with exch2 + blank tiles:
655      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
656        face dimensions.
657      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
658        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
659        and INI_SPHERICAL_POLAR_GRID.
660      change test-experiment global_ocean.90x40x15:
661      - split the domain in many more tiles (9x4 tiles of 10x10 each);
662      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
663      - update results of both test (std & dwnslp).
664    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
665       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
666    o model/src:
667      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
668        and fix initialisation when using sigma-coords.
669    o model/src:
670     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
671       to their current value at the beginning of forward_step.F": add a new run-time
672       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
673     - set doResetHFactors=T in the following test exp:
674        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
675        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
676        and tutorial_global_oce_in_p (nonLinFS in p)
677    o pkg/ecco
678      - added IES cost term
679    o verification/advect_xz
680      - scale down the depth by 1/100 (from 200 km to just 2.km)
681      - add secondary test using divergent flow, r-star and implicit vertical advection.
682      - add note (check_conserve_TS.txt) and matlab script to check global
683        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
684    o pkg/rbcs:
685      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
686    o pkg/obcs (Stevens BCs):
687      - fix various problems in the phase speed computations of the Stevens
688        boundary conditions:
689        - sign error for western and southern boundaries,
690        - time tendencies were underestimated by factor of dTracerLev and some just
691          zero (for multidim advection schemes) -> now estimate time tendencies
692          from difference between previous (n) time level and the one before (n-1);
693          this requires storing a field per tracer per boundary, also in the pickup
694          files.
695        - replace deltaTmom in cflMer/Zon computation with dTracerLev
696        - set default phase velocity to cflMer/Zon
697      - update verification experiment exp4.stevens
698    o pkg/generic_advdiff (implicit_r):
699      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
700        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
701      - fix implicit vertical diffusion or advection with NonLin FreeSurf
702        (was using current recip_hFacC instead of future recip_hFacC): set future
703        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
704        solver S/R ;
705      - fill diagnostics of vertical advective fluxes (computed from tendency)
706        when using implicit vert. advection;
707      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
708         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
709         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
710         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
711    o pkg/diagnostics:
712      - add diags for T & S tendency which goes through Adams-Bashforth.
713    
714    checkpoint63f (2011/11/30)
715    o pkg/obcs/obcs_calc_stevens.F:
716      - join some loops to reduce number of if-statements
717      - fix a bug in code for northern and southern boundaries.
718    o pkg/seaice/seaice_init_varia.F
719      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
720        caused zero ice-velocities for the B-grid code
721    o pkg/seaice/seaice_init_fixed.F
722      - fix a bug in the initialisation of the second metric terms
723        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
724      - this affects all seaice configurations with useCurviLinearGrid = .true.
725        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
726        = .true. (default)
727      - the only verification experiment affected is global_ocean.cs32x15:
728        icedyn, seaice, and seaice_dynmix (AD)
729    o pkg/thsice/thsice_diagnostics_state.F
730      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
731        not contain garbage that can lead to surprises in diagstats_calc.F
732    o model/src:
733      - move bi,bj loops inside INTEGR_CONTINUITY ;
734      - call INTEGR_CONTINUITY directly from forward_step.F
735        (previously called from momentum_correction_step.F)
736      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
737        forward_step.F and pkg/ecco/the_main_loop.F
738    o model/src/do_oceanic_phys.F:
739      - reset addMass to zero only if useICEFRONT ;
740      - separated k-loop for rhoInSitu calculation ;
741      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
742        and at constant T,S (= WdRHOdP);
743      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
744        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
745        transport of locally-referenced potential density);
746        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
747    o gluemnc:
748      - replace ncrcat with ncks when adding variables to *.glob.nc
749      - change the way variables without record dimensions are handled so that
750        files that have variables with and without record variables can be glued:
751        add a record dimension with a new unique name to be able to differentiate
752        between variable with and without a-prior record dimensions. Remove
753        this record dimension before adding the variable to the *.glob.nc file.
754        This procedure automatically works also for grid.*.nc files that do not
755        have any record dimension.
756    o verification/cpl_aim+ocn:
757      - generate new reference output on baudelaire (gfortran, mpich2) (previously
758        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
759    o pkg/obcs/obcs_calc_stevens.F:
760      - add code for northern and southern boundaries.
761      - reorder some loops to save some operations and so that drFBar can be scalar
762    o model/src:
763      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
764        truncation) and add diagnostics for Adams-Bashforth tendency increment.
765      - update test-exp. AD output:
766        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
767      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
768        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
769        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
770        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
771        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
772        tutorial_plume_on_slope.
773    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
774      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
775      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
776      does not even come with an F77 compiler anymore, this should not be
777      a limitation
778    
779    checkpoint63e (2011/11/06)
780    o pkg/seaice adjoint of LSR:
781      - substantially rework STORE dirs.
782      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
783        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
784        and only perform SOLV_MAX_FIXED adjoint iters.
785        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
786        always goes to same record, meaning that the last forward field will be
787        the one used in the adjoint - an approximation.
788      - now produces non-zero LSR-related gradients, and acceptable gradients for
789        An's zonal (x-z) test case (to be checked in)
790      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
791        (but these are screwed up by the thermodynamics in the first place);
792        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
793        output_adm.txt also reflects changes to seaice_lsr
794      - global_ocean.cs32x15:
795        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
796          (output_adm.seaice.txt was updated)
797        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
798          (output_adm.seaice_dynmix.txt)
799    o test-exp. exp4+stevens:
800      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
801    o pkg/seaice (lsr solver):
802      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
803        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
804      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
805      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
806        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
807      - compute (with new S/R) and print initial (+ free-driff sol. if available)
808        and final residual of linearised system.
809  o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity  o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
810    (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)    (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
