4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o testreport
8     - add option to use a home made wrapper around "make"
9     - remove MITGCM_IEEE env. variable (no longer active)
10    o pkg/shelfice
11     - improve computation of friction velocity for velocity dependent
12       exchange coefficients: include velocities into SHELFICEBoundaryLayer
13       block to average velocities vertically
14     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
15    o Modify diagonal solvers, now three versions (upon request):
16      #ifndef SOLVE_DIAGONAL_AUTODIFF
17        1. default version (dating back a while ago)
18      #else /* def SOLVE_DIAGONAL_AUTODIFF */
19      # ifdef SOLVE_DIAGONAL_KINNER
20        2. adjoinable version with k-innermost loop (G. Forget)
21      # else
22        3. adjoinable vectorized version of 2.
23      # endif
24      #endif /* SOLVE_DIAGONAL_AUTODIFF */
25      All flags are currently set within routines, but could/should be moved to CPP-options.
26      Array bounds for 1. are as before, for 2.,3. cover the entire domain
27      (could be changed for 1. too).
28    o verification/lab_sea (fwd):
29      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
30        use 7 categories (except hb87), new solve4temp params (except salt_plume),
31        constant salinity (=4) or variable salinity (salt_plume) done through
32        SItracer.
33    o pkg/seaice:
34      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
35      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
36         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
37        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
38        SEAICE_freeze got retired) but already better than previously with
39        SEAICE_freeze=123456.7 deg.C;
40      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
41        (safer multi-threaded setting); always set SEAICEuseEVP;
42      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
43        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
44        stop if multiple specifications for the same coeff; make sure default
45        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
46    o pkg/obcs:
47      - allow to switch to upwind 1rst order advection scheme for the advective
48        flux computation at the open-boundary; disabled for adjoint built.
49    o pkg/ptracers:
50      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
51      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
52      - add parameter to decide when to start a tracer; use internal flag to
53        know which tracer to step-forward; switch this internal flag at the top
54        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
55        for adjoint built.
56    o pkg/seaice:
57      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
58      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
59      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
60    o pkg/ecco:
61      - fix writing of output file DiagnosCost_ClimSalt/Theta
62        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
63    o pkg/seaice:
64      - add missing initialisation of COR_ICE array in dynsolver.F
65      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
66        compiled either way, and is tested in all exps (multidim was only tested
67        in lab_sea ad before).
68      - cosmetic change to prepare for future addition of ITD. no change to results.
69        no defaults change.
70      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
71      - by lack of adequate verification experiments, I further used custom versions
72        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
73        should be correct.
74      - avoid recomputations in ad.
75    o array initialisation in adjoint mode:
76      1) pkg/mom_common/mom_calc_ke.F:
77        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
78        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
79        part this initialisation is gone, resulting in Floating Point Exception
80        (caught by open64 compiler with debug option).
81      2) model/src/convective_weights.F
82        set output convectCount over the full array range (instead of doing
83        an update): this fix a similar issue when called within recomputation (adjoint)
84        which could by-pass the initialisation (normally done in the caller S/R).
85    o pkg/seaice:
86      - final version of turbulent flux params, as agreed at MIT ice meet:
87           SEAICE_mcPheePiston (default is ~ 0.000875)
88           SEAICE_mcPheeTaper (default is 0.)
89           SEAICE_frazilFrac (defualt is 1.)
90           SEAICE_mcPheeStepFunc (default is false)
91      - changes results at trunction error level
92      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
93    o added pkg/frazil:
94      - see frazil_description.tex for details
95      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
96    o pkg/shelfice/shelfice_thermodynamics.F
97      - fix exponents for velocity dependent exchange coefficients: change
98        from 2/3(=0) to 0.66666666666666667
99      - move computation of velocity dependent exchange coefficients into
100        separate loop, so that it applies to both thermodynamics
101      - move some divisions by constants out of loops
102    
103    checkpoint63j (2012/02/16)
104    o pkg/seaice:
105      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
106      - SItracer:  added run time params, and allow coupling to ocn salinity.
107    o pkg/seaice: remove (almost) all divisions by constants within loops
108      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
109      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
110      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
111      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
112    o pkg/seaice :
113      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
114        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
115      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
116      - add permanent SItflux diag that corresponds to TFLUX but includes
117        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
118      - allow activation/testing of a fix for suspected missing term in
119        ocn-ice heat budget (to be confirmed). To test this, you want to
120        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
121        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
122      - no change in results, fwd or ad.
123    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
124      - switch to variable freezing point.
125           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
126      - bug fix : the sublimation term that was missing is now activated.
127           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
128      - bug fix : flooding sign term for SIsal0.NE.0.
129           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
130    o pkg/seaice:
131      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
132        is now the default, and the old default constant freezing point is recovered
133        with SEAICE_tempFrz0    = -1.96,
134             SEAICE_dTempFrz_dS = 0.,
135      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
136      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
137      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
138        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
139      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
140        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
141      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
142        seaice_growth r149 for legacy branch (no results change).
143      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
144        from I. Fenty).
145      - results did not change except for global_ocean.cs32x15, mostly due to the
146        switch to variable freezing point (see above item for detail).
147    o pkg/thsice:
148      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
149        seawater freezing in thsice_calc_thickn (not used).
150    o pkg/seaice: turbulent flux term specification via run time params.
151      - replace CPP switches with run time switches to facilitate testing
152      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
153                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
154      - added runtime parameter : SEAICEturbFluxFormula
155      - move Mcphee constants to SEAICE_PARAMS.h
156      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
157                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
158                 remove seaice_summary call (moved to seaice_init_fixed)
159      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
160        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
161      - seaice_summary.F : add missing report of read turbulent flux term set up
162                           and SITRACER.
163      - seaice_check.F : check range; inform and stop if retired CPPs are used
164                         (incl. SEAICE_AGE).
165      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
166             CPP switch, same computation as before for the different options.
167      - change results at the truncation level.
168    o pkg/seaice:
169      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
170        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
171        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
172      - update verification/*/input*/data.seaice:
173        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
174        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
175        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
176        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
177    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
178      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
179        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
180        difference in results only due to machine truncation.
181      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
182        MaykutPolySatVap; keep MIN_LWDOWN.
183      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
184      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
185        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
186    o pkg/salt_plume:
187      - isolate saltPlumeFlux array exch into a specific S/R called from
188        do_oceanic_phys.F
189      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
190    o verification:
191      - move untested set-up to MITgcm_contrib/verification_other.
192    o pkg/seaice:
193      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
194    o pkg/seaice:
195      - seaice_solve4temp.F (keeping results unchanged):
196        * add 2 future run-time params to select which saturation vapor pressure
197          formula is used and how post-iteration fluxes are set.
198          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
199        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
200          the linearized expression to stay consistent with tsurf finding.
201      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
202        can be < 0.
203    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
204      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
205        conductive heat flux F_c , and add it explicitly when updating tsurf as
206        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
207        so that now F_ia has a consistent meaning through the entire routine.
208        This causes differences at truncation level: update output of fwd exp.
209        global_ocean.cs32x15.seaice.
210    o pkg/seaice:
211      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
212        of arrays, sign/direction of fluxes; no effect on results.
213      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
214        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
215        note: this should have been done before changing celsius2K default.
216      - to keep results unchanged, add back old value of celsius2K in verification
217        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
218      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
219        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
220        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
221        freezing temp is consistent with value in seaice_growth.F ; this causes
222        differences at machine truncation level: update lab_sea AD output (3/4).
223    o pkg/seaice:
224      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
225        and climsst/sss even when using seaice (to prevent calculation that might
226        use SST on land); does not affect any verification exp.
227      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
228        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
229    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
230      over land (non-legacy code)
231    o vectorize salt_plume package:
232      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
233      - this code computes plumebk everywhere (also over land), thus requires
234        code to avoid divisions by zero and catch the case of kLev=Nr.
235      - efficiency of salt_plume_frac is still sub-optimal
236    o tools (genmake2):
237      - fix makefile NAME specification (option: -makefile NAME) by adding
238        "-f $MAKEFILE" in few places where it was missing including makedepend
239        command (contribution from Paul).
240    
241    checkpoint63i (2012/01/24)
242    o model/src:
243      - add factorized versions of some EOS code to find_rho.F,
244        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
245    o model/src:
246      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
247      - change default celsius2K from 273.16 to 273.15
248      - to keep results unchanged, add back old value of celsius2K in verification
249        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
250         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
251    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
252      to make TAF generate vectorizable code
253    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
254       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
255       have flags that do this more efficiently.
256    o pkg/diagnostics/diagstats_calc.F
257      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
258    o pkg/obcs (with exch2):
259      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
260        and remove code (in obcs_readparms.F) which was based on EXCH of indices
261        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
262    o pkg/exf and seaice exp:
263      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
264        so that switching off area & heff advection flags does not affect results.
265      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
266      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
267        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
268        results of verification experiments: 1D_ocean_ice_column(fwd),
269        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
270        and offline_exf_seaice (all 4).
271    o pkg/seaice:
272      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
273        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
274      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
275        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
276        not multi-dim advection;
277      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
278        SHORTWAVE_HEATING #undef.
279    o optim: make Makefile more robust (?)
280    o pkg/obcs:
281      * fix treatment of obcs_read_pickup for TAF
282    o pkg/shelfice:
283      * add missing initialisation of num_shifwflx
284      * new adjoint verification exp. for isomip
285      * change Prandtl and Schmidt numbers from generic formulations
286        (in terms of model diffus. and visc.) to separate runtime
287        parameters, with Holland and Jenkins (1999) default values.
288    o pkg/exf (interpolation):
289      - extended input field (2 rows) near the N & S poles:
290        * fill in with the symetric value (when even Nb of data in longitude)
291        * add average value at the poles only for scalar quantities ; for vector
292          component interpolation, skip the averaging and keep duplicated values,
293          unless the 2 components have same location (uvInterp=T) in which case
294          interpolate the 2 components together using S/R EXF_INTERP_UV.
295      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
296        together: this allows to account properly for local orientation when
297        averaging at N & S pole.
298      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
299        exf-interpolation near N & S poles. Undef by default.
300      - add debug check/print on 1rst iter if debugLevel >=2.
301    o pkg/exf:
302      - change masking flags definition (no longer "parameter"), put them in
303        common block and set them in S/R EXF_INIT_FIXED.
304      - change recognized masking flag from s,u,v to c,w,s since the mask
305        to use (maskC,W,S) depends on position on model grid and has little to
306        do with scalar/vector difference; fix masking if using P-coordinates.
307      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
308        and update results of exp. global_with_exf (x2).
309      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
310    o pkg/obcs
311      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
312    o pkg/exf (interpolation):
313      - assume periodicity in X only if input field cover full longitude range.
314      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
315        and should vectorise).
316      - fix input lat of the 2 added row (in case we provide N.pole data).
317    
318    checkpoint63h (2011/12/30)
319    o pkg/seaice:
320      - change declaration of UVM from _RL to _RS in order to get B-grid
321        uIce,vIce monitor when _RS = real*4
322    o pkg/offline:
323      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
324      - compute vertical velocity if not read from file (switch on exactConserv
325        & staggerTimeStep);
326      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
327    o verification:
328      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
329        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
330        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
331      - update output of exp. global_ocean.cs32x15.viscA4 after changing
332        grid-file angles (used here for coriolis-3d);
333      - remove (or gzip) few files not needed to run fizhi-cs experiments.
334    o pkg/exf (vector interpolation):
335      - rotate vector component toward local grid-axis orientation using grid-angles
336        (stored in GRID.h) instead of locally computed rotation angle; keep old code
337        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
338    o pkg/seaice:
339      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
340        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
341    o pkg/PKG_OPTIONS.h files:
342      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
343        outside of the #ifdef ALLOW_THISPKG / #endif block.
344      - update verification/*/code/PKG_OPTIONS.h files.
345    o add a verification experiment (offline_exf_seaice/input.seaice) that test
346      the B-grid LSOR solver
347    o pkg/seaice: sort out emissivity and long wave radiation step 2:
348      - add emissivity for snow and ice as new run-time parameters
349        (unfortunately) that default to the corresponding exf values; this
350        changes results in most verification experiments so that for backward
351        compatibility these parameter have to be set explicitly to inconsistent
352        values (ugly);
353      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
354        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
355        until we agree how to handle this bug properly
356    o pkg/exf (interpolation):
357      - add a set of run-time param ({inputfield}_interpMethod), one for
358        each interpolated input field, to select the interpolation method
359        with a value of zero switching off the interpolation;
360      - print interpolation parameters to standard output;
361      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
362        (to use instead runoff_interpMethod=0 in data.exf).
363      - simplify default setting of interpolation parameters (for all fields,
364        set position to match model grid cell-center position, leading to trivial
365        interpolation in case of regular Lat-Lon grid) and fix for the case of
366        non-uniform delY.
367    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
368       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
369       this factor is absolutely required, because the lw exitance (= out-going
370       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
371       where the reflectivity rho = 1-emissivity for conservation reasons. Once
372       this is established, we can remove the CPP-Flag (if we want to).
373    o pkg/seaice:
374      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
375        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
376      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
377        what the name implies (and not emissivity*BoltzmannConstant), this means
378        the old default value of 5.5e-8 now means
379        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
380        S/R exf_readparms
381      - FV-discretization of the B-grid LSOR solver, turn on with
382        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
383        of the calling routine dynsolver, so that B and C-grid code look a
384        little more alike.
385      - fix index bugs in ostres.F (B-grid code)
386    o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
387    o pkg/seaice/seaice_readparms.F: make ocean_emissivity*stefanBoltzmann the
388      default for SEAICE_emissivity, if useEXF; requires setting a wrong
389      parameter value in global_ocean.cs32x15/input.seaice/data.seaice for
390      backward compatiblity
391    o model/src: use sigmaR in calc_ivdc
392    
393    checkpoint63g (2011/12/16)
394    o pkg/seaice/seaice_growth.F:
395      fix heat conservation of the coupled ocean-seaice system.
396      when SEAICE_HEAT_CONSERV_FIX is defined, the mismatch of
397      solid vs liquid water treatment is resolved via QNET.
398    o pkg/seaice/seaice_growth.F:
399      add missing term for sublimation in saltFlux, which was breaking conservation.
400    o pkg/seaice/seaice_model.F:
401      Remove this patholigical case treatment in evolution branch,
402      where it is un-necessary and breaks conservation.
403      Update global_ocean.cs32x15/results accordingly for
404      output.seaice.txt output_adm.seaice.txt and output_adm.seaice_dynmix.txt
405    o model/src:
406      useRealFreshWaterFlux: remove masking of EmPmP (using maskInC) in
407      external_forcing_surf.F and apply mask directly in S/R SOLVE_FOR_PRESSURE.
408    o pkg/obcs:
409      modify Stevens boundary conditions so that S/R obcs_calc_stevens computes
410      tendency for temperature and salinity that is then applied to update
411      theta and salt in S/R obcs_apply_ts; this requires proper masking of all
412      horizontal advection and diffusion contributions on the boundary (in
413      S/Rs gad_advection, gad_calc_rhs, gmredi_rtransport, gmredi_calc_diff), and
414      removing the mask in S/R timestep_tracer. The advantage of this approach is
415      that the updated tracer values include contributions from the surface
416      forcing and vertical diffusion.
417      This modification changes exp4.stevens because of vertical diffusion.
418    o model/src:
419      change non-curvilinear grid setting to also work with exch2 + blank tiles:
420      - move delX,delY to new header file (SET_GRID.h) and adjust length to 1rst
421        face dimensions.
422      - new S/R INI_LOCAL_GRID to define model tile-local grid (using same units
423        as delX,delY) and called from S/R INI_CARTESIAN_GRID, INI_CYLINDER_GRID
424        and INI_SPHERICAL_POLAR_GRID.
425      change test-experiment global_ocean.90x40x15:
426      - split the domain in many more tiles (9x4 tiles of 10x10 each);
427      - switch to exch2 and remove 1 blank-tile (but only for MPI test).
428      - update results of both test (std & dwnslp).
429    o pkg/diagnostics/diagstat_calc.F: fix problem with non-initialised halos in
430       tmp-fields for TARGET_NEC_SX at the cost of extra loops and less vectorisation
431    o model/src:
432      - take sigma-coords related code out of update_etah.F into new S/R UPDATE_ETAWS
433        and fix initialisation when using sigma-coords.
434    o model/src:
435     - improve Gael's changes from Jan 14, 2011 "addition of an 'update' of hfacc etc.
436       to their current value at the beginning of forward_step.F": add a new run-time
437       switch "doResetHFactors" (default=false) and use it to do (or not) the resetting.
438     - set doResetHFactors=T in the following test exp:
439        global_ocean.90x40x15/input (rStar) & input.dwnslp (linFS),
440        global_ocean.cs32x15/input.seaice (rStar), hs94.cs-32x32x5/input.impIGW (linFS)
441        and tutorial_global_oce_in_p (nonLinFS in p)
442    o pkg/ecco
443      - added IES cost term
444    o verification/advect_xz
445      - scale down the depth by 1/100 (from 200 km to just 2.km)
446      - add secondary test using divergent flow, r-star and implicit vertical advection.
447      - add note (check_conserve_TS.txt) and matlab script to check global
448        conservation of T & S with NonLin-FreeSurf and Adams-Bashforth.
449    o pkg/rbcs:
450      - add missing relaxUFile & relaxVFile in namelist (in rbcs_readparms.F).
451    o pkg/obcs (Stevens BCs):
452      - fix various problems in the phase speed computations of the Stevens
453        boundary conditions:
454        - sign error for western and southern boundaries,
455        - time tendencies were underestimated by factor of dTracerLev and some just
456          zero (for multidim advection schemes) -> now estimate time tendencies
457          from difference between previous (n) time level and the one before (n-1);
458          this requires storing a field per tracer per boundary, also in the pickup
459          files.
460        - replace deltaTmom in cflMer/Zon computation with dTracerLev
461        - set default phase velocity to cflMer/Zon
462      - update verification experiment exp4.stevens
463    o pkg/generic_advdiff (implicit_r):
464      - fix implicit vertical advection conservation with AB and/or NonLin-FreeSurf
465        (remove Tr*d/dz(w) in gad_implicit_r.F and add it in gad_calc_rhs.F);
466      - fix implicit vertical diffusion or advection with NonLin FreeSurf
467        (was using current recip_hFacC instead of future recip_hFacC): set future
468        recip_hFac in thermodynamics.F and pass & use it in all vertical implicit
469        solver S/R ;
470      - fill diagnostics of vertical advective fluxes (computed from tendency)
471        when using implicit vert. advection;
472      - update output of exp that uses NonLin-FreeSurf & implicit vertical diffusion:
473         global_ocean.90x40x15 (fwd+AD), global_ocean.cs32x15 (4 fwd +4 AD),
474         tutorial_global_oce_in_p (fwd), tutorial_tracer_adjsens (AD)
475         and cpl_aim+ocn (used in ocean); to be fixed: bottom_ctrl_5x5.
476    o pkg/diagnostics:
477      - add diags for T & S tendency which goes through Adams-Bashforth.
478    
479    checkpoint63f (2011/11/30)
480    o pkg/obcs/obcs_calc_stevens.F:
481      - join some loops to reduce number of if-statements
482      - fix a bug in code for northern and southern boundaries.
483    o pkg/seaice/seaice_init_varia.F
484      - undo resetting UVM=0 that has slipped in unnoticed in r1.49 and
485        caused zero ice-velocities for the B-grid code
486    o pkg/seaice/seaice_init_fixed.F
487      - fix a bug in the initialisation of the second metric terms
488        k2AtC and k2AtZ: k2AtC was set to the value of k2AtZ and k2AtZ was 0.
489      - this affects all seaice configurations with useCurviLinearGrid = .true.
490        and SEAICEuseDynamics = .true. (default) and SEAICEuseMetricTerms
491        = .true. (default)
492      - the only verification experiment affected is global_ocean.cs32x15:
493        icedyn, seaice, and seaice_dynmix (AD)
494    o pkg/thsice/thsice_diagnostics_state.F
495      - only for TARGET_NEC_SX: initialise all of tmpFld, so that overlap does
496        not contain garbage that can lead to surprises in diagstats_calc.F
497    o model/src:
498      - move bi,bj loops inside INTEGR_CONTINUITY ;
499      - call INTEGR_CONTINUITY directly from forward_step.F
500        (previously called from momentum_correction_step.F)
501      - call UPDATE_ETAH from integr_continuity.F and update initialise_varia.F,
502        forward_step.F and pkg/ecco/the_main_loop.F
503    o model/src/do_oceanic_phys.F:
504      - reset addMass to zero only if useICEFRONT ;
505      - separated k-loop for rhoInSitu calculation ;
506      - add 2 diagnostics for wVel*delta^k(Rho) at constant pressure (= WdRHO_P)
507        and at constant T,S (= WdRHOdP);
508      NOTE: change diagnostics WRHOMASS : this is now simply the Vertical transport
509        of In-Situ Density (Anomaly) (=wVel*rho^bar-k) (previously was Vertical
510        transport of locally-referenced potential density);
511        to recover old diag: (WRHOMASS)_old = (WRHOMASS)_new -1/2 * (WdRHOdP)
512    o gluemnc:
513      - replace ncrcat with ncks when adding variables to *.glob.nc
514      - change the way variables without record dimensions are handled so that
515        files that have variables with and without record variables can be glued:
516        add a record dimension with a new unique name to be able to differentiate
517        between variable with and without a-prior record dimensions. Remove
518        this record dimension before adding the variable to the *.glob.nc file.
519        This procedure automatically works also for grid.*.nc files that do not
520        have any record dimension.
521    o verification/cpl_aim+ocn:
522      - generate new reference output on baudelaire (gfortran, mpich2) (previously
523        from old aces-grid cluster, ao + ifort) and update 'run_cpl_test' script.
524    o pkg/obcs/obcs_calc_stevens.F:
525      - add code for northern and southern boundaries.
526      - reorder some loops to save some operations and so that drFBar can be scalar
527    o model/src:
528      - re-arrange extrapolation calculation in Adams-Bashforth S/R (affects machine
529        truncation) and add diagnostics for Adams-Bashforth tendency increment.
530      - update test-exp. AD output:
531        1D_ocean_ice_column, bottom_ctrl_5x5, lab_sea.noseaicedyn, obcs_ctrl;
532      and FWD output: exp4 (x3), fizhi-cs-32x32x40, fizhi-cs-aqualev20,
533        front_relax (x3), global_ocean.90x40x15 (x2), global_ocean.cs32x15 (x5),
534        global_ocean_ebm, ideal_2D_oce, internal_wave, isomip (x3), lab_sea (x4),
535        matrix_example, MLAdjust (x5), natl_box (x2), tutorial_advection_in_gyre,
536        tutorial_global_oce_in_p, tutorial_global_oce_latlon and
537        tutorial_plume_on_slope.
538    o pkg/diagnostics/diagstats_calc.F: add special code for TARGET_NEC_SX
539      that vectorises. This code uses 3 extra 2D fields, F90 array assignments
540      and F90 intrinsic routines SUM, MINVAL, MAXVAL, but since TARGET_NEC_SX
541      does not even come with an F77 compiler anymore, this should not be
542      a limitation
543    
544    checkpoint63e (2011/11/06)
545    o pkg/seaice adjoint of LSR:
546      - substantially rework STORE dirs.
547      - add new flag SEAICE_LSR_ADJOINT_ITER and parameter SOLV_MAX_FIXED
548        this flag will do SOLV_MAX_ITERS but only store SOLV_MAX_FIXED fields
549        and only perform SOLV_MAX_FIXED adjoint iters.
550        If flag SEAICE_LSR_ADJOINT_ITER is undef-ined, the store in the iteration
551        always goes to same record, meaning that the last forward field will be
552        the one used in the adjoint - an approximation.
553      - now produces non-zero LSR-related gradients, and acceptable gradients for
554        An's zonal (x-z) test case (to be checked in)
555      - lab_sea: produces acceptable gradients for lab_sea with forward/backward LSR
556        (but these are screwed up by the thermodynamics in the first place);
557        reduce from 4 to 3 timesteps to avoid t.d. issue as temporary solution;
558        output_adm.txt also reflects changes to seaice_lsr
559      - global_ocean.cs32x15:
560        * the "default" input_ad.seaice has been re-defined to always exclude dynamics
561          (output_adm.seaice.txt was updated)
562        * new input_ad.seaice_dynmix tests a forward LSR / backward free-drift
563          (output_adm.seaice_dynmix.txt)
564    o test-exp. exp4+stevens:
565      - switch off pTracers and nonHydrostatic (restart problems with NH); update output
566    o pkg/seaice (lsr solver):
567      - put coriolis term into FORCEX,Y (as in seaice_evp.F; previously in rhsU,V only);
568        update output (change truncation) of FWD test exp lab_sea & global_ocean.cs32x15
569      - fix SEAICEuseFREEDRIFT for new OBCS version (ndef OBCS_UVICE_OLD)
570      - new parameter "LSR_mixIniGuess" allows (if=2,4) to mix free-drift solution
571        into initial guess for linearised solver; use weight ~ (1/err)^2,4.
572      - compute (with new S/R) and print initial (+ free-driff sol. if available)
573        and final residual of linearised system.
574  o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity  o pkg/pp81: add diagnostics for vertical eddy viscosity and diffusivity
575    (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)    (requires new subroutines pp81_init_fixed.F/pp81_diagnostics_init.F)
