4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ecco: allow user defined cost function contributions
8    o testreport:
9      Allow to choose (per experiment) the list of tested output variables
10       and the main variable (used to issue a pass/FAIL ) ;
11      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
12      - default is unchange: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
13      Also modify printing of summary:
14       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
15       b) echo the list of tested variables in the individual summary.txt of
16          each experiment.
17    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
18      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
19      (but still depend on the tile decompostion of the domain).
20    o pkg/seaice: change a discretization detail to make the B-grid code
21      "more symmetric". This change is likely to remove all "ridges/leads" that
22      where quasi-aligned with the grid in B-grid solutions. It may also be
23      the solution to the stress coupling issues with the B-grid.
24    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
25      remove .cvsignore from input dir. (since testreport no longer run here).
26    o pkg/thsice:
27     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
28     - fix reshaping of sea-ice just after advection:
29       melt all the ice only if ice-volume is too small.
30     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
31       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
32     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
33    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
34      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
35    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
36      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
37      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
38      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
39      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
40      -> update output.txt
41    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
42     this affects truncation error: -> update output.txt of exp:
43      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
44      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
45    
46    checkpoint59f
47    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
48    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
49      a bounded range (in forward mode)
50    o pkg/ecco, ctrl, autodiff and mom_common:
51     internal parameter controls, completements of implementations
52    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
53    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
54      (not seem any difference in testing results).
55    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
56       at face corners.
57    o pkg/generic_advdiff:
58     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
59      loop range indices for computing vertical advection tendency
60      and do the calculation in the interior only (no overlap) ;
61      for now, only implemented for SOM advection (to save CPU time).
62     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
63    o exch2 adjoint
64      First set of changes:
65      - add exch2 hand-written adjoint templates
66      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
67        This will require cleanup in pkg/autodiff/*.F
68        (changed routines currently kept separate in verif. code/)
69      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
70        that used to hide exch2 or cubed-sphere specific code
71        (commented via 'cph-exch2')
72    o pkg/seaice
73      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
74    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
75       output of global_ocean.cs32x15.thsice .
76    
77    checkpoint59e
78    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
79      for B-grid vector (not yet tested) and C-grid vector (<- only used
80      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
81    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
82      (#ifdef ALLOW_SALT_PLUME)
83    o gather_2d/scatter_2d: removed halo regions
84    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
85      scheme and the corresponding test case (under front_relax dir). For now,
86      only available with Skew-flux form and not yet tested in realistic set-up.
87      adjoint: store directives updated, but gradient checks deteriorated,
88      so maybe GM/Redi adjoint is now broken.
89    o seaice adjoint
90      * add AREA, HEFF, HSNOW as control variable
91        (should not change lab_sea results)
92      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
93    o pkg/seaice:
94      * added computation of saltFlux in seaice_growth;
95        For time being, sea ice salinity is assumed constant
96        contribution of snow flooding to freshening of sea ice is neglected.
97        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
98        defaults to 0.0 in order to maintain backward compatibility.
99        Typical values for SEAICE_salinity are 4 to 10 g/kg.
100      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
101      * added SEAICE_availHeatFrac, which specifies fraction of surface level
102        heat content used to melt or grow ice
103      * commented out cap of HICE: it helps keep ice thinner
104      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
105      * applied OBCS T/S mask to HEFFM sea ice mask
106    
107    checkpoint59d
108    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
109     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
110     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
111    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
112     and change default value of parameter "GM_Small_Number";
113     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
114       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
115       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
116    o pkg/ecco: cost function when applying pkg/smooth to controls
117    o pkg/ctrl: add forcingPrecond run time parameter
118    o pkg/seaice:
119     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
120     - fix bug in metric terms of u-equation in LSR solver (implicit part),
121       changes verification/lab_sea
122     - rearrange implicit part of u-equation in LSR solver to make it easier to
123       read, understand, and debug. This causes changes at the truncation level.
124     - fix (serious) bug in the boundary conditions (sign error in the implicit
125       part) of the LSR solver. Changes all LSR results.
126     - fixed problem with HSNOW initialization to avoid thick snow when AREA
127       is initilized with small values - does not change lab_sea results.
128     - added HsnowFile initialization capability
129    o pkg/smooth: addition to model/src and pkg/ctrl so allow
130     initialization of pkg/smooth and application to control vector
131    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
132    o dependencies: pkg/profiles requires pkg/cal
133    o pkg/profiles:
134     - added option ALLOW_PROFILES_GENERICGRID
135         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
136         that interpolation information (grid points and coefficients) is provided
137         within the netcdf input files.
138         -> sample matlab scripts can be found in MITgcm_contrib/gael
139         that allow you to prepare netcdf input files.
140     - also modified: cleaner include statements, cleaner error print statements,
141       cleaner stops when error, and more tests of the netcdf input files consistency.
142    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
143    o pkg/seaice:
144     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
145       requires a new routine: seaice_diagnostics_fill.F
146     - make sure that seaice does not move if not forced (pressure replacement
147       method, Hibler and Ip, 1995), changes results
148     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
149     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
150       It is turned off by default (=-1.), because it changes the results.
151     - make it possible to read AREA from a file, too.
152    
153    checkpoint59c
154    o add S/R and diagnostics for oceanic mixed-layer depth
155    o move GMRedi call after all vertical mixing schemes (including KPP)
156    o pkg/thsice:
157     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
158      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
159    o pkg/obcs:
160     - bug fix for balance code
161    o pkg/seaice:
162      - allow values of SEAICE_elasticParm > 1
163      - add new parameter SEAICE_evpTauRelax as an alternative
164        to SEAICE_elasticParm
165      - make lsr boundary conditions free slip (by default), changes result
166      - add code for no slip boundary conditions for lsr
167      - set minimum of zeta to zero (and not 4e8) (changes results)
168      - add a cap on AREA after advecting AREA if seaice_growth is not called
169    o change calculation of Visbeck K:
170      - no longer depend on tapering scheme; instead, compute slope (limited
171        by GM_maxSlope). this is equivalent to what was comuted before with
172        clipping or linear tappering.
173      - fix vertical averaging (wrong by 1/2 level)
174      - leave the old version (but will not be maintained) within
175        #ifdef OLD_VISBECK_CALC / #endif
176      - update output of exp. ideal_2D_oce
177    o change error catch in calc_r_star to improve vectorization
178    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
179      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
180    o adjoint:
181      Re-organized adjoint checkpointing according to Matt Mazloff
182      (but with modifs/completions/cleanups)
183      Storing is now bundled into large arrays to optimized I/O
184      (and second step in cleanup of the_main_loop)
185    
186    checkpoint59b
187    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
188      - export/import (between ocean & coupler) fields needed for ocean DIC.
189    o pkg/seaice:
190      - get rid of three more exchanges seaice_calc_viscosities (required
191        different loop boundaries in seaice_lsr and seaice_ocean_stress)
192      - bug fix in seaice_ocean_stress (update of lab_sea required)
193      - reduce loop boundaries to necessary minimum also in seaice_evp
194      - go back to the old way of computing deltaC/Z as the adjoint likes that
195        better
196    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
197      passive tracer to an Age Tracer) + update output.txt
198    o pkg/exf:
199      - implement A-grid / C-grid selection for wind-stress input files.
200      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
201      for now, in exf_bulk_largeyeager04.F only :
202      - change implementation for case where windspeed + 2. components wind-stress
203        are read-in. AND use rhoConstFresh to convert evap.
204    o pkg/seaice:
205      - use correct EXCH_UV for wind-forcing (on A-grid).
206      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
207        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
208    o pkg/exf:
209      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
210      EXF_INTERPOLATION:
211      - merge global_with_exf/code version of exf_interp_read.F
212        to the main code ;
213      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
214        reading the file ; Important: This options needs to be defined to recover
215        previous code.
216        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
217      - no longer loose real*8 precision along the way when using exf_iprec=64.
218    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
219      - change discretisation of evp-solver in order to avoid another exchange
220        (changes lab_sea) and clean up a little
221      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
222        help the adjoint (this also changes the results slightly)
223      - add a few "_d 0" where they had been missing in seaice_evp.F
224      - cleaning up: remove unused seaice_calc_rhs.F
225    o pkg/exf: some cleaning-up:
226      - change various "constants" into runtime parameters
227      - cleaned-up Large&Yeager04 routine which should eventually
228        replace exf_bulkformulae.F (changed names of S/R and CPP)
229        and merged various ALLOW_ATM_WIND options
230     only used with thsice pkg (in thsice_get_exf.F):
231      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
232        which are used when useStabilityFct_overIce=TRUE (= the default)
233      - change default values of ice & snow emissivity and scale downward LW
234        by ice & snow emissivity.
235    o pkg/thsice:
236     fix few little problems, in thsice_calc_thickn.F:
237      - growth vertically (and not laterally) if iceFrac == iceMaskMax
238      - melt only laterally if hIce < hThinIce (as the comments say)
239      and in thsice_extend.F:
240      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
241      - start to form ice as soon as the minimum ice-volume is reachable.
242     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
243      and cpl_aim+ocn
244    o pkg/kpp
245     - move computation of surface related input fields to KPP into a new
246       subroutine kpp_forcing_surf.F
247     - remove wrong (within bi,bj loops) EXCH calls.
248     - little cleaning (add argument myThid in last position, cvs header ...)
249     - for now, fix conservation problem by exchanging KPPviscAz (may not
250       be the best fix)
251    o pkg/seaice
252     - check for inconsistent evp parameter/cpp-flag combination
253     - remove leftover errIO flat for obsolete name list error handling
254    o OpenAD
255     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
256    
257    checkpoint59a
258    o pkg/seaice: some parameter clarifications and a little bit of clean up
259    o pkg/thsice: rename run-time parameters:
260       himin       -> hIceMin
261       himin0      -> hThinIce
262       hihig       -> hThickIce
263       i0          -> i0swFrac
264       transCoef   -> bMeltCoef
265       frac_energy -> fracMelting
266      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
267       with default values (for now) that do not change the results.
268      remove old version of thsice vars advection in pkg/seaice.
269    o in FFIELDS.h:
270      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
271      - make pLoad & sIceLoad always available (but still only used if
272         ATMOSPHERIC_LOADING is #define).
273    o pkg/kpp: replaced _KPP_RL with _RL
274    o bug fixes for vertical diffusivity computations when both KPP and
275        3D diffusivity arrays are used.
276    o pkg/seaice: fix bug in evp solver, while doing that
277      - change (improve?) discretization of stress computations for both
278        cgrid-lsr and evp solver
279      - add a new routine to compute strain rates
280      - the above changes lab_sea results
281      - add no slip conditions for evp solver (off by default), lsr-version
282        may follow
283      - fix exchange for shear at Z-points (does not change lab_sea)
284      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
285        (to force the user to pick a time step since there is not "safe" way
286        of choosing it)
287      - add principal stress diagnostics
288      - rearrange fields for evp a little to avoid having to call a: too many
289        exchanges and b: exchanges for stress trensor components which we do
290        not have.
291      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
292        of evp, complete rewrite for lsr case (latter is does not yet work
293        in all cases)
294    o pkg/kpp: add code to have mixing in shelf ice caverns
295      - add myThid to all kpp routines (long overdue)
296    
297    checkpoint59
298    o pkg/exf:
299      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
300        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
301      - move exf header files from lower_case.h to UPPER_CASE.h ;
302        add missing cvs Header & Name
303      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
304      - add namelist param. selectStressGridPosition, exf_monFreq
305      - retire many _CLIM routines, and remove data.exf_clim
306        + params moved to data.exf
307        + climsst, climsss now handled by exf_set_gen, i.e.
308          climss?period=0 refers to constant field,
309          climss?period=-12 to monthly forcing
310      - split up namelists in data.exf
311    o pkg/seaice:
312      - remove seaice_exch and seaice_exch_uv
313      - remove superfluous exchange of theta
314      - add myThid to seaice_budget_ocean/ice
315      - add new interface for atmospheric wind forcing (C-grid only)
316        + new routine
317        + two new field (taux, tauy for stress over ice)
318        + removed one global field (DAIRN) for C-grid case only
319    o pkg/thsise
320      - 2nd set of modifs for thsice adjoint in conjunction with exf
321    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
322    
323    checkpoint58y_post
324    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
325      vertical diffusivity, similar to that in MOM4; turned on using
326      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
327      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
328    o Added capability for 3D specification of background vertical diffusion
329      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
330      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
331      "data" file that contains the 3D vertical diffusivity coefficients.
332    o ice dynamics (pkg/seaice) with thsice thermodynamics:
333      - add code within pkg thsice to advect & diffuse sea-ice fields
334      similar to (and will replace) what has been added in  seaice_advdiff.F,
335      but: - conserving Mass, Heat & Salt.
336           - better when using non-linear advection scheme (not yet fully tested)
337           - can also be used in atmospheric set-up (for now, only the diffusion).
338    
339    checkpoint58x_post
340    o IO option for global-file compact format:
341      - add options when generating topology (utils/exch2/matlab-topology-generator)
342      - add I/O capability (pkg/mdsio).
343      - adapt utils/matlab/rdmds.m to read this format.
344      for now long-line format not yet supported by pkg/mdsio (& exch2).
345    o shelfice: add a few diagnostics
346    
347    checkpoint58w_post
348    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
349      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
350      (and replace horiVertRatio in NH code).
351      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
352                         and tutorial_plume_on_slope (sensitive to truncation)
353    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
354      directly to drive seaice model (C-grid only)
355    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
356     - reintroduce computation of wind from stress,
357     - compute tau (in exf_bulkformulae.F) from windstress averaged to
358       mass points to avoid tau = 0
359     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
360    o rdmnc.m: make it work with "global" files created with gluemnc
361    o rdmnc.m : some improvements in dealing with singleton dimension
362      (tested on all testreport mnc output files).
363    o genmake2: disable pkg/profiles if netcdf test fails.
364    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
365    o move call to cal_readparms up to make calendar parameters/variable available
366      to all packages
367    
368    checkpoint58v_post
369    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
370      useDynP_inEos_Zc tested.
371    o pkg/exf: changes to properly interpolate/mask/scale initial fields
372    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
373      and portions thereof.  See read_cs.txt for description and examples.
374    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
375      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
376      following the great-circle arc between those 2 points.
377    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
378      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
379    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
380     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
381     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
382     - still needs work (not working with some options ; efficiency to improve)
383       and serious testing.
384     - use this scheme for temperature & salinity in 2 advection test exp.:
385       advect_xy & advect_xz, respectively.
386    
387    checkpoint58u_post
388    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
389    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
390    o testreport: add option "-skipdir" to skip some test.
391    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
392      momentum calculation.
393    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
394    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
395      remove checkpoint.F and the_correction_step.F (no longer used);
396      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
397    o add option (linFSConserveTr) to correct for tracer source/sink due to
398      Linear Free surface
399    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
400    o pkg/thsice: fix reading mnc-pickups
401    
402    checkpoint58t_post
403    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
404    o pkg/mdsio:
405     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
406       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
407       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
408     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
409     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
410       either MDS_READ_FIELD or MDS_WRITE_FIELD )
411     - new S/R (to replace MDSWRITEMETA), which allows to write more
412       informations (variable names, time ...) to meta files.
413     - modify rdmds.m to give back the meta file content.
414    o pkg/diagnostics: change vertical interpolation to be safer, and more
415       flexible (define p-levels to interpolate to in data.diagnostics);
416      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
417       diagnostic pointer.
418    o pkg/seaice: more cleaning up of seaice_growth, added many comments
419    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
420    o fix multi-category seaice:
421     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
422       SEAICE_MULTICATEGORY
423     - fix short wave heat flux
424    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
425       and allow to use EVP solver. Change forward lab_sea: test both EVP
426       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
427    o Initial check-in of lab_sea adjoint
428      (very similar to natl_box_adjoint/code_seaice)
429      * used C-grid and EVP solver
430      * used KPP, GM/Redi
431      * uses inAdExact=.TRUE.
432      * gradient checks fail for both ADM and TLM
433        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
434        f.d. gradients actually seem more problematic than ADM, TLM gradients;
435        issue is related to forward mismatch between g77 an ifort
436    o pkg/seaice: overhaul of thermodynamics
437     - growth.F and groatb.F are replaced by new routine seaice_growth.F
438     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
439     - move a few global fields out of SEAICE.h into seaice_growth.F and
440       make them 2D (FICE/QNETO/ ...)
441     - remove FO (it is the same as QNETO)
442     - introduce a few local fields to avoid modifying external fields such
443       as atemp, etc.
444    
445    checkpoint58s_post
446    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
447      changed exf_set_gen.F so that
448        genperiod=0 means input file is one time-constant field and
449        genperiod=-12 means input file contains 12 monthly means
450    o CG2D: use pre-computed solver main-diagonal (stored in common block);
451      this affects truncation error ; generate new output file for exp. which
452      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
453        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
454        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
455        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
456        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
457        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
458    o start implementation of deep-atmosphere and anelastic formulation
459    o verification: remove 2nd copy of input files and use script "prepare_run"
460      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
461    o mom_common/vecinv/fluxform: fix a few initialisation isssues
462    o profiles: fix for multithreaded case
463    
464  o diagnostics: rename few diags:  o diagnostics: rename few diags:
465    s/'PRESSURE'/'RCENTER '/g    s/'PRESSURE'/'RCENTER '/g
466    s/'TICE    '/'oceFreez'/g    s/'TICE    '/'oceFreez'/g
