4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/fizhi:
8        clean-up turbulence cold-start switch: decided in fizhi_init_vars.F, stored
9        in common bloc (fizhi_coms.h) and then passed as argument up to S/R TURBIO.
10    o pkg/exch2:
11      - add argument "updateCorners" to S/R exch2_get_uv_bounds (enable to
12        activate EXCH_IGNORE_CORNERS in vector EXCH S/R).
13      - switch 1rst EXCH call to IGNORE_CORNERS (instead of UPDATE_CORNERS)
14        but keep the 2nd with UPDATE_CORNERS: this prevents overwriting good data
15        with bad ones coming from a not-yet-updated halo.
16        This should fix the problem when sNx <> sNy and GCD(sNx,sNy) < 2*Olx.
17    o pkg/frazil:
18        move FrzForcT diag from frazil_diagnostics_state.F to frazil_calc_rhs.F
19        http://mitgcm.org/pipermail/mitgcm-devel/2012-March/005384.html
20    o model/src/config_check.F: add a check for OLx>sNx/OLy>sNy
21    o verification/lab_sea
22      * #undef SEAICE_EXCLUDE_FOR_EXACT_AD_TESTING
23      * #define ALLOW_SST_CONTROL & ALLOW_SST_CONTROL
24      * nTimeSteps 3 -> 4
25      * changed reference output accordingly
26    o pkg/ctrl:
27      * fix ctrl_get_gen for xx_sst, xx_sss
28    o pkg/fizhi:
29      - fix 2 calls to S/R GRD2MSC (argument igrd) in update_earth_exports.F
30        update results of exp. fizhi-cs-32x32x40 (fail with only 6 digits for cg2d)
31      - by default, use new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE);
32        fix few out-of-bounds indices in referencing vars (initialise igrd to 1);
33        clean-up fizhi_turb.F (remove unused & uninitialised qdiaglsm array).
34    o pkg/gmredi:
35      - add diagnostic of Redi (main diagnonal) vertical diffusive flux of Temp
36    o pkg/fizhi:
37      - fix few initialisation and multi-tile Pb: aqualev & gridalt now pass the
38        (old)aces open64 tuv test.
39    o pkg/icefront: fix bug and reorder loop in icefront_init_varia.F
40    o pkg/mom_vecinv:
41      - fix 1 loop range in mom_vecinv.F to be like all the other loops which
42        set/update gu,gv/Diss (fix Pb of uninitialised fVerUkp in admom_vecinv
43        with non-lin free-surf).
44    o model/src: move k-loop outside of i/j-loops when (re-)computing R_low
45      in ini/update_masks_etc.F in order to avoid -O3 optimization problems with
46      some compilers (gfortran 4.6.0 on MacOS)
47    o momentum:
48      - separate fVer?(:,:,kUp) & fVer?(:,:,kDown) in argument list of MOM_FLUXFORM
49        & MOM_VECINV subroutines (to help TAF). This fixes Pb of uninitialised
50        fVer?(kUp) in admom_fluxform with non-lin free-surf or bottom control.
51    
52    checkpoint63k (2012/03/17)
53    o model/src:
54       - selectAddFluid (ALLOW_ADDFLUID): add missing term in horizontal momentum
55         flux-form (mom_fluxform.F) and vertical momentum (calc_gw.F) equations.
56       - SOLVE_DIAGONAL: switch default to use adjoinable & vectorized version
57         (#undef SOLVE_DIAGONAL_LOWMEMORY); update output of exp. front_relax.bvp.
58    o model/src: solve_*diagonal.F
59       - replace division with multiplication by inverse (similar to original version)
60         update output of AD exp. global_ocean.90x40x15.
61       - fix pkg/gmredi/gmredi_calc_psi_bvp.F & pkg/ggl90/ggl90_calc.F
62         to enable the use of the vectorized & differentiable solve_tridiagonal.F
63       - test exp. global_ocean.90x40x15/input_ad: switch to advection scheme 20 for
64         vertical advection (to get solve_tridiagonal tested in AD mode).
65    o pkg/seaice: ECCO-CLIVAR merge:
66      1. seaice AREA relaxation
67         * CPP option: SEAICE_ALLOW_AREA_RELAXATION
68         * runtime flag: SEAICE_tauAreaObsRelax
69      2. modified global mean cost imbalance code: CPP option
70          ALLOW_SSH_GLOBMEAN_COST_CONTRIBUTION
71    o another iteration on solve_*diagonal.F
72       Make choices independent of AUTODIFF
73       Default will be the adjoinable vectorized version.
74       Alternative choices are:
75       * non-adjoinable original version with low memory footprint:
76         #define SOLVE_DIAGONAL_LOWMEMORY
77       * still adjoinable but does not vectorize (k as inner-most loop):
78         #define SOLVE_DIAGONAL_KINNER (keeping SOLVE_DIAGONAL_LOWMEMORY undef)
79    o testreport
80     - add option to use a home made wrapper around "make"
81     - remove MITGCM_IEEE env. variable (no longer active)
82    o pkg/shelfice
83     - improve computation of friction velocity for velocity dependent
84       exchange coefficients: include velocities into SHELFICEBoundaryLayer
85       block to average velocities vertically
86     - add TAF store directives for SHI_ALLOW_GAMMAFRICT
87    o Modify diagonal solvers, now three versions (upon request):
88      #ifndef SOLVE_DIAGONAL_AUTODIFF
89        1. default version (dating back a while ago)
90      #else /* def SOLVE_DIAGONAL_AUTODIFF */
91      # ifdef SOLVE_DIAGONAL_KINNER
92        2. adjoinable version with k-innermost loop (G. Forget)
93      # else
94        3. adjoinable vectorized version of 2.
95      # endif
96      #endif /* SOLVE_DIAGONAL_AUTODIFF */
97      All flags are currently set within routines, but could/should be moved to CPP-options.
98      Array bounds for 1. are as before, for 2.,3. cover the entire domain
99      (could be changed for 1. too).
100    o verification/lab_sea (fwd):
101      - update the 4 fwd lab_sea test experiment: no longer SEAICE_GROWTH_LEGACY,
102        use 7 categories (except hb87), new solve4temp params (except salt_plume),
103        constant salinity (=4) or variable salinity (salt_plume) done through
104        SItracer.
105    o pkg/seaice:
106      - rename parameters: SIsalFrac to SEAICE_saltFrac & SIsal0 to SEAICE_salt0;
107      - remove old parameters ( SEAICE_freeze, SEAICEturbFluxFormula, SEAICE_gamma_t,
108         SEAICE_gamma_t_frz, SEAICE_availHeatTaper & SEAICE_availHeatFracFrz)
109        from SEAICE_PARMS.h ; still need to fix seaice_cost_sst.F (broken when
110        SEAICE_freeze got retired) but already better than previously with
111        SEAICE_freeze=123456.7 deg.C;
112      - move setting of facOpenGrow/Melt from SEAICE_INIT_FIXED to SEAICE_READPARMS
113        (safer multi-threaded setting); always set SEAICEuseEVP;
114      - setting of ocean-ice turb. flux coeff: moved from SEAICE_CHECK to
115        SEAICE_READPARMS & SEAICE_INIT_FIXED (this fixes wrong summary report);
116        stop if multiple specifications for the same coeff; make sure default
117        SEAICE_mcPheePiston is compatible with drF(1) & deltaT.
118    o pkg/obcs:
119      - allow to switch to upwind 1rst order advection scheme for the advective
120        flux computation at the open-boundary; disabled for adjoint built.
121    o pkg/ptracers:
122      - rename PTRACERS_RESTART.h -> PTRACERS_START.h
123      - rename ptracers_fields_blocking_exchanges.F -> ptracers_fields_blocking_exch.F
124      - add parameter to decide when to start a tracer; use internal flag to
125        know which tracer to step-forward; switch this internal flag at the top
126        of forward_step.F (new S/R PTRACERS_SWITCH_ONOFF); for now, not enabled
127        for adjoint built.
128    o pkg/seaice:
129      - add SEAICE_SIZE.h anywhere in the code where SEAICE.h is included ;
130      - move MULTDIM declaration and setting from SEAICE.h to SEAICE_SIZE.h ;
131      - keep experiment offline_exf_seaice truly single category (set MULTDIM=1).
132    o pkg/ecco:
133      - fix writing of output file DiagnosCost_ClimSalt/Theta
134        and DiagnosCost_DriftSalt/Theta (if multi-tiles per proc).
135    o pkg/seaice:
136      - add missing initialisation of COR_ICE array in dynsolver.F
137      - merging SEAICE_MULTICATEGORY define and undef cases. Now the same code is
138        compiled either way, and is tested in all exps (multidim was only tested
139        in lab_sea ad before).
140      - cosmetic change to prepare for future addition of ITD. no change to results.
141        no defaults change.
142      - added run time param SEAICE_multDim (7 for SEAICE_MULTICATEGORY, 1 otherwise).
143      - by lack of adequate verification experiments, I further used custom versions
144        of global_ocean.cs32x15 to test multicat or not, with pickup or not. All
145        should be correct.
146      - avoid recomputations in ad.
147    o array initialisation in adjoint mode:
148      1) pkg/mom_common/mom_calc_ke.F:
149        add full array initialisation of KE inside mom_calc_ke.F (ALLOW_AUTODIFF_TAMC):
150        The S/R which calls MOM_CALC_KE initialises KE but in some recomputation
151        part this initialisation is gone, resulting in Floating Point Exception
152        (caught by open64 compiler with debug option).
153      2) model/src/convective_weights.F
154        set output convectCount over the full array range (instead of doing
155        an update): this fix a similar issue when called within recomputation (adjoint)
156        which could by-pass the initialisation (normally done in the caller S/R).
157    o pkg/seaice:
158      - final version of turbulent flux params, as agreed at MIT ice meet:
159           SEAICE_mcPheePiston (default is ~ 0.000875)
160           SEAICE_mcPheeTaper (default is 0.)
161           SEAICE_frazilFrac (defualt is 1.)
162           SEAICE_mcPheeStepFunc (default is false)
163      - changes results at trunction error level
164      - ifdef SEAICE_EXTERNAL_FLUXES, disallow SEAICE_waterAlbedo
165    o added pkg/frazil:
166      - see frazil_description.tex for details
167      - verification experiment is global_with_exf/input.yearly; changes output.yearly.txt
168    o pkg/shelfice/shelfice_thermodynamics.F
169      - fix exponents for velocity dependent exchange coefficients: change
170        from 2/3(=0) to 0.66666666666666667
171      - move computation of velocity dependent exchange coefficients into
172        separate loop, so that it applies to both thermodynamics
173      - move some divisions by constants out of loops
174    
175    checkpoint63j (2012/02/16)
176    o pkg/seaice:
177      - overhaul of seaice_summary.F after feb 2012 clean-up of seaice_growth.F etc.
178      - SItracer:  added run time params, and allow coupling to ocn salinity.
179    o pkg/seaice: remove (almost) all divisions by constants within loops
180      in seaice_growth.F and seaice_solve4temp.F, this changes (only) the cg2d
181      results of global_ocean.cs32x15.seaice from 16 to 11 digits (but only
182      those, caused by 1/QI -> recip_QI) -> update output.seaice.txt,
183      output_adm.seaice_dynmix.txt and also lab_sea: output_adm.evp.txt
184    o pkg/seaice :
185      - simplify McPhee tapering, and allow to use it with SEAICEturbFluxFormula
186        = 1 or 2, using newly added run time parameter SEAICE_availHeatTaper.
187      - fix d_AREAbyATM, d_AREAbyOCN, d_AREAbyICE diags I broke in r1.148.
188      - add permanent SItflux diag that corresponds to TFLUX but includes
189        ice+snow. Hence SItflux-TFLUX should match the ice+snow heat budget.
190      - allow activation/testing of a fix for suspected missing term in
191        ocn-ice heat budget (to be confirmed). To test this, you want to
192        undef SEAICE_DISABLE_HEATCONSFIX, and then set the run time param
193        SEAICEheatConsFix to .TRUE. that also allows the 'SIaaflux' diagnostic.
194      - no change in results, fwd or ad.
195    o global_ocean.cs32x15/results: 3 changes following from the pkg/seaice commit below:
196      - switch to variable freezing point.
197           Results change : cg2d -> 1 digits; ad -> 3-6-6 digits.
198      - bug fix : the sublimation term that was missing is now activated.
199           Results change : cg2d -> 2 digits; ad -> 8-6-6 digits.
200      - bug fix : flooding sign term for SIsal0.NE.0.
201           Result change : cg2d -> 8 digits; ad -> 11-12-9 digits.
202    o pkg/seaice:
203      - unified freezing point treatment : the old SEAICE_VARIABLE_FREEZING_POINT
204        is now the default, and the old default constant freezing point is recovered
205        with SEAICE_tempFrz0    = -1.96,
206             SEAICE_dTempFrz_dS = 0.,
207      - retire SEAICE_freeze (= the old way of specifycing the constant freezing point)
208      - remove ALLOW_SEAICE_FLOODING brackets; run time switch is already there.
209      - bug fix (thanks to M. Losch) : the sublimation term that was missing is now
210        activated. To reproduce old results with this bug define SEAICE_DISABLE_SUBLIM.
211      - bug fix (silly me) : flooding sign term (seaice_growth.F r 1.149line 1211)
212        was wrong for SIsal0.NE.0. Changes cs32x15 results (see above item for detail).
213      - bug fix (thanks to O. Jahn) : area loss for melting  got messed up in
214        seaice_growth r149 for legacy branch (no results change).
215      - introduce SEAICE_CAP_SUBLIM : caps sublimation heat flux in solve4temp (code
216        from I. Fenty).
217      - results did not change except for global_ocean.cs32x15, mostly due to the
218        switch to variable freezing point (see above item for detail).
219    o pkg/thsice:
220      - fix and simplify interface to salt_plume pkg ; diagnose directly amount of
221        seawater freezing in thsice_calc_thickn (not used).
222    o pkg/seaice: turbulent flux term specification via run time params.
223      - replace CPP switches with run time switches to facilitate testing
224      - retired CPPs : MCPHEE_OCEAN_ICE_HEAT_FLUX,
225                       GRADIENT_MIXED_LAYER_TURBULENCE_FACTOR
226      - added runtime parameter : SEAICEturbFluxFormula
227      - move Mcphee constants to SEAICE_PARAMS.h
228      - seaice_readparms.F : read turbulent flux term params (SEAICEturbFluxFormula;
229                 SEAICE_availHeatFrac/Frz, or SEAICE_gamma_t/_frz if apply);
230                 remove seaice_summary call (moved to seaice_init_fixed)
231      - seaice_init_fixed.F : set SEAICE_availHeatFrac/Frz depending on
232        SEAICEturbFluxFormula, and seaice_summary call (moved from seaice_readparms)
233      - seaice_summary.F : add missing report of read turbulent flux term set up
234                           and SITRACER.
235      - seaice_check.F : check range; inform and stop if retired CPPs are used
236                         (incl. SEAICE_AGE).
237      - seaice_growth.F : unified use of SEAICE_availHeatFrac/Frz, without
238             CPP switch, same computation as before for the different options.
239      - change results at the truncation level.
240    o pkg/seaice:
241      - remove un-used parameters LAD & MAX_TICE ; add new run-time parameters:
242        useMaykutSatVapPoly (default=F), postSolvTempIter (default=2) and
243        SEAICE_wetAlbTemp (default=-1e-3). Remove option SEAICE_SOLVE4TEMP_LEGACY.
244      - update verification/*/input*/data.seaice:
245        to reproduce previous results with former #defined SEAICE_SOLVE4TEMP_LEGACY
246        code, set useMaykutSatVapPoly=T & postSolvTempIter=0 ;
247        and to reproduce previous results with former non-SOLVE4TEMP_LEGACY code,
248        set SEAICE_wetAlbTemp=0 & SEAICE_snowThick=0.
249    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY):
250      - remove LEGACY code for solving for tsurf (A1,A2,A3) but maintain the same
251        algorithm (same choice: useMaykutPolySatVap=T, postSolvTempIter=0);
252        difference in results only due to machine truncation.
253      - remove MAX_TICE (tsurf is always =< TMELT anyway); keep MIN_TICE if using
254        MaykutPolySatVap; keep MIN_LWDOWN.
255      - adapt SEAICE_MODIFY_GROWTH_ADJ code (untested) to non-legacy formulation.
256      - update output of verification exp. lab_sea (4 fwd: 11 cg2d digits except hb87,
257        + 3 AD: 6 digits except evp) and offline_exf_seaice.seaice (12 digits).
258    o pkg/salt_plume:
259      - isolate saltPlumeFlux array exch into a specific S/R called from
260        do_oceanic_phys.F
261      - add interface to pkg/salt_plume (filling of saltPlumeFlux) in pkg/thsice.
262    o verification:
263      - move untested set-up to MITgcm_contrib/verification_other.
264    o pkg/seaice:
265      - retire old way of SEAICE_AGE. Now replaced with ALLOW_SITRACER.
266    o pkg/seaice:
267      - seaice_solve4temp.F (keeping results unchanged):
268        * add 2 future run-time params to select which saturation vapor pressure
269          formula is used and how post-iteration fluxes are set.
270          Temporary set these 2 params according to option SOLVE4TEMP_LEGACY;
271        * New piece of code (not used) to update surf. atmos. heat flux F_ia using
272          the linearized expression to stay consistent with tsurf finding.
273      - seaice_freedrift.F avoid floating exception in sqrt(y) since y=sqrt(x*x)-x
274        can be < 0.
275    o pkg/seaice/seaice_solve4temp.F (SOLVE4TEMP_LEGACY undef):
276      - remove from F_ia (and from it's derivative dFiDTs1) the contribution of
277        conductive heat flux F_c , and add it explicitly when updating tsurf as
278        solution of: Fc = Fia + d/dT(Fia - Fc) *delta.tsurf
279        so that now F_ia has a consistent meaning through the entire routine.
280        This causes differences at truncation level: update output of fwd exp.
281        global_ocean.cs32x15.seaice.
282    o pkg/seaice:
283      - lots of editing/cleaning in seaice_solve4temp.F + better documentation
284        of arrays, sign/direction of fluxes; no effect on results.
285      - replace hard coded 273.16 (=previous value of celsius2K) by celsius2K
286        in seaice_budget_ocean.F & seaice_solve4temp.F (SOLVE4TEMP_LEGACY part);
287        note: this should have been done before changing celsius2K default.
288      - to keep results unchanged, add back old value of celsius2K in verification
289        exp. input*/data : lab_sea (AD), offline_exf_seaice (fwd+AD) & seaice_obcs
290      - replace hard coded seawater freezing temp in seaice_solve4temp.F (part
291        SOLVE4TEMP_LEGACY) of 271.20 (=previous value of celsius2K + default
292        value of SEAICE_freeze) by celsius2K+SEAICE_freeze so that seawater
293        freezing temp is consistent with value in seaice_growth.F ; this causes
294        differences at machine truncation level: update lab_sea AD output (3/4).
295    o pkg/seaice:
296      - mask (in exf_init_fixed.F) atemp,aqh,evap,precip,runoff,lwflx,areamask
297        and climsst/sss even when using seaice (to prevent calculation that might
298        use SST on land); does not affect any verification exp.
299      - apply mask to taux,tauy (in seaice_get_dynforcing.F); update output
300        of lab_sea.fd & lab_sea.hb87 and global_ocean.cs32x15.seaice_dynmix.
301    o pkg/seaice/seaice_growth.F: add mask to avoid non-zero ice thickness
302      over land (non-legacy code)
303    o vectorize salt_plume package:
304      - add extra code to salt_plume_frac and salt_plume_tendency_apply_s
305      - this code computes plumebk everywhere (also over land), thus requires
306        code to avoid divisions by zero and catch the case of kLev=Nr.
307      - efficiency of salt_plume_frac is still sub-optimal
308    o tools (genmake2):
309      - fix makefile NAME specification (option: -makefile NAME) by adding
310        "-f $MAKEFILE" in few places where it was missing including makedepend
311        command (contribution from Paul).
312    
313    checkpoint63i (2012/01/24)
314    o model/src:
315      - add factorized versions of some EOS code to find_rho.F,
316        define USE_FACTORIZED_EOS to turn it on (default for TARGET_NEC_SX)
317    o model/src:
318      - add celsius2K to namelist PARM01; remove unused recip_rhoNil from PARAMS.h;
319      - change default celsius2K from 273.16 to 273.15
320      - to keep results unchanged, add back old value of celsius2K in verification
321        exp. input*/data : aim.5l_cs, 1D_ocean_ice_column, lab_sea (fwd),
322         global_ocean.cs32x15(seaice) & cpl_aim+ocn(input_atm).
323    o model/src: add a little initialisation trick to find_rho.F and find_alpha.F
324      to make TAF generate vectorizable code
325    o pkg/seaice/seaice_evp.F: add code (copied from CICE) that avoids underflows.
326       Turn on by defining SEAICE_EVP_ELIMINATE_UNDERFLOWS. Most compilers
327       have flags that do this more efficiently.
328    o pkg/diagnostics/diagstats_calc.F
329      - for TARGET_NEC_SX fix the treatment of the scaling factor tmpFac=scaleFact
330    o pkg/obcs (with exch2):
331      - derive OB indices in overlap region from OB-InsideMask (in obcs_init_fixed.F)
332        and remove code (in obcs_readparms.F) which was based on EXCH of indices
333        (through buffer) and did not account for exch2 (e.g., CS-grid) topology.
334    o pkg/exf and seaice exp:
335      - change offline_exf_seaice.seaicetd test exp. to use default DIFF1 value (=0)
336        so that switching off area & heff advection flags does not affect results.
337      - change default EXF_LWDOWN_WITH_EMISSIVITY to #define in EXF_OPTIONS.h
338      - keep exp. seaice_obcs & 1D_ocean_ice_column(ad) unchanged (using #undef
339        EXF_LWDOWN_WITH_EMISSIVITY) and, using pkg/exf default emissivities, update
340        results of verification experiments: 1D_ocean_ice_column(fwd),
341        global_ocean.cs32x15.seaice(fwd+ad) & seaice_dynmix(ad), lab_sea (all 8)
342        and offline_exf_seaice (all 4).
343    o pkg/seaice:
344      - remove array YNEG, RIVER, TMIX (replaced by local var) from common block;
345        remove also areaNm1 & hEffNm1 when SEAICE_GROWTH_LEGACY is undef.
346      - fix bug: areaNm1 & hEffNm1 are needed in seaice_growth (SEAICE_GROWTH_LEGACY)
347        but were not filled when resp. SEAICEadvArea=F & SEAICEadvHeff=F and
348        not multi-dim advection;
349      - fix seaice_growth.F to compile with both SEAICE_GROWTH_LEGACY and
350        SHORTWAVE_HEATING #undef.
351    o optim: make Makefile more robust (?)
352    o pkg/obcs:
353      * fix treatment of obcs_read_pickup for TAF
354    o pkg/shelfice:
355      * add missing initialisation of num_shifwflx
356      * new adjoint verification exp. for isomip
357      * change Prandtl and Schmidt numbers from generic formulations
358        (in terms of model diffus. and visc.) to separate runtime
359        parameters, with Holland and Jenkins (1999) default values.
360    o pkg/exf (interpolation):
361      - extended input field (2 rows) near the N & S poles:
362        * fill in with the symetric value (when even Nb of data in longitude)
363        * add average value at the poles only for scalar quantities ; for vector
364          component interpolation, skip the averaging and keep duplicated values,
365          unless the 2 components have same location (uvInterp=T) in which case
366          interpolate the 2 components together using S/R EXF_INTERP_UV.
367      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
368        together: this allows to account properly for local orientation when
369        averaging at N & S pole.
370      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
371        exf-interpolation near N & S poles. Undef by default.
372      - add debug check/print on 1rst iter if debugLevel >=2.
373    o pkg/exf:
374      - change masking flags definition (no longer "parameter"), put them in
375        common block and set them in S/R EXF_INIT_FIXED.
376      - change recognized masking flag from s,u,v to c,w,s since the mask
377        to use (maskC,W,S) depends on position on model grid and has little to
378        do with scalar/vector difference; fix masking if using P-coordinates.
379      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
380        and update results of exp. global_with_exf (x2).
381      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
382    o pkg/obcs
383      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
384    o pkg/exf (interpolation):
385      - assume periodicity in X only if input field cover full longitude range.
386      - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
387        and should vectorise).
388      - fix input lat of the 2 added row (in case we provide N.pole data).
389    
390    checkpoint63h (2011/12/30)
391    o pkg/seaice:
392      - change declaration of UVM from _RL to _RS in order to get B-grid
393        uIce,vIce monitor when _RS = real*4
394    o pkg/offline:
395      - new S/R OFFLINE_RESET_PARMS for resetting main-model params (switch off flags);
396      - compute vertical velocity if not read from file (switch on exactConserv
397        & staggerTimeStep);
398      - fix output of ptracer monitor iter & time for default PTRACERS_monitorFreq.
399    o verification:
400      - update grid-files (in tutorial_held_suarez_cs/input and fizhi-cs-32x32x40/input)
401        with grid-angle generated using "utils/matlab/cs_grid/cubeCalcAngle.m":
402        fix Pb in yG definition @ 2 missing corners (previously yG was averaged);
403      - update output of exp. global_ocean.cs32x15.viscA4 after changing
404        grid-file angles (used here for coriolis-3d);
405      - remove (or gzip) few files not needed to run fizhi-cs experiments.
406    o pkg/exf (vector interpolation):
407      - rotate vector component toward local grid-axis orientation using grid-angles
408        (stored in GRID.h) instead of locally computed rotation angle; keep old code
409        available with exf option EXF_USE_OLD_VEC_ROTATION (undef by default).
410    o pkg/seaice:
411      - allow to compile with exf options ALLOW_ATM_TEMP or ALLOW_DOWNWARD_RADIATION
412        undefined. Fix and remove the stop when ALLOW_RUNOFF is undefined.
413    o pkg/PKG_OPTIONS.h files:
414      - move #include "CPP_OPTIONS.h" just after #include "PACKAGES_CONFIG.h",
415        outside of the #ifdef ALLOW_THISPKG / #endif block.
416      - update verification/*/code/PKG_OPTIONS.h files.
417    o add a verification experiment (offline_exf_seaice/input.seaice) that test
418      the B-grid LSOR solver
419    o pkg/seaice: sort out emissivity and long wave radiation step 2:
420      - add emissivity for snow and ice as new run-time parameters
421        (unfortunately) that default to the corresponding exf values; this
422        changes results in most verification experiments so that for backward
423        compatibility these parameter have to be set explicitly to inconsistent
424        values (ugly);
425      - the exf-flag EXF_LWDOWN_WITH_EMISSIVITY then gets rid off the hard-wired
426        emissivities of 0.97 associated with lwdownloc in S/R seaice_solve4temp
427        until we agree how to handle this bug properly
428    o pkg/exf (interpolation):
429      - add a set of run-time param ({inputfield}_interpMethod), one for
430        each interpolated input field, to select the interpolation method
431        with a value of zero switching off the interpolation;
432      - print interpolation parameters to standard output;
433      - refine exf_check.F accordingly ; stop if USE_NO_INTERP_RUNOFF is defined
434        (to use instead runoff_interpMethod=0 in data.exf).
435      - simplify default setting of interpolation parameters (for all fields,
436        set position to match model grid cell-center position, leading to trivial
437        interpolation in case of regular Lat-Lon grid) and fix for the case of
438        non-uniform delY.
439    o pkg/exf/exf_radiation.F: add the factor ocean_emissivity to lwdown, for
440       within #ifdef EXF_LWDOWN_WITH_EMISSIVITY/#endif. Unless ocean_emissivity=1.
441       this factor is absolutely required, because the lw exitance (= out-going
442       long wave radiation) is emissivity*stefanBoltzmann*T^4 + rho*lwdown,
443       where the reflectivity rho = 1-emissivity for conservation reasons. Once
444       this is established, we can remove the CPP-Flag (if we want to).
445    o pkg/seaice:
446      - qualify a stop statement in S/R seaice_check: EXF_READ_EVAP and
447        ALLOW_BULKFORMULAE are only required if SEAICE_EXTERNAL_FLUXES is defined
448      - sort out emissivity and long wave radiation, step 1: make SEAICE_emissivity
449        what the name implies (and not emissivity*BoltzmannConstant), this means
450        the old default value of 5.5e-8 now means
451        5.5e-8/5.670e-8 = 0.97001763668430343479 as ocean_emissivity in
452        S/R exf_readparms
453      - FV-discretization of the B-grid LSOR solver, turn on with
454        SEAICE_LSRBNEW. This new solver also involves a slight re-organization
455        of the calling routine dynsolver, so that B and C-grid code look a
456        little more alike.
457      - fix index bugs in ostres.F (B-grid code)
458  o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better  o pkg/seaice/seaice_ocean_budget.F: change (unused) code to make it look better
