3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6  untagged  o doc/api_reference added
7      - a framework for building an API Reference Manual using all
8        the "protex" comments embedded in the code
9      - see pkg/generic_advdiff, pkg/mnc for examples
10    o MNC:
11      - make myThid the last argument for all subroutines
12      - new default for the grid files: NO halos
13      - add useMNC and other run-time flags
14      - separate per-file-group handling of the unlimited dimension
15      - early initialization of MNC w/ flags read at the eeboot stage
16        and lookup tables set in initialize_fixed
17      - write all MNC output to a freshly-created directory
18    o thermodynamics sea-ice (thsice) is now tested with testreport.
19    o test exp. advect_cs: use the standard cs32 grid ; update output.
20    o Added functionality to grdchk:
21      pick global i,j,k position (or nearest wet) where to perform check.
22    
23    checkpoint52l_post
24    o new land formulation:
25      a) use ground enthalpy as prognostic variable to ensure exact
26         energy conservation.
27      b) account for water temperature and for latent heat of freezing
28         in all processes (rain, run-off, ground storage)
29      c) compute surface and ground temperature implicitly.
30    o aim_v23 modification for new land model:
31      a) Treat separately land / ocean / sea-ice surface fluxes
32         to allow implicit computation of land & sea-ice surface temp.
33      b) add snow precipitation.
34    checkpoint52l_pre
35    
36    o fix problem (when 1 tile is empty) in min/max monitor.
37    o fix bug in timeAve (u,vZetatave in common block)
38    o no restoring terms under ice for pkg/seaice
39    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
40    o bug fix for pkg/seaice pickups
41    o change MNC call locations and add coordinate attributes
42    o mask vorticity at the corner ; affects global_ocean.cs output
43    o fix ini_curvilinear_grid ; test CS experiments with mpi
44    o aim.5l_cs: modify sea-ice fraction input file ; update output
45    o exf: Adding simple range check routine for exf fields after read
46    
47    checkpoint52k_post
48    o removed top-level directory "diags"
49      - we migrated these functions to pkg/timeave a long time ago
50    o fixed bug introduced in pkg/monitor
51    o accuracy ctrlprec = 32 insuffient for gradient checks using
52      averaged fields (I/O via cost_averages)
53      -> use ctrl.h in active_file*.F to control I/O precision.
54    o paramter list of CALL ADTHE_MAIN_LOOP
55    o added initial do_the_model_io to ecco
56    o set all ...Freq to zero after cost_final
57      taveFreq, dumpFreq, pChkptFreq
58    o MAIN and ECCO differentiability restored
59    
60    checkpoint52j_post
61    o fix nchklev in tamc.h for global_ocean...
62    o Bringing flow and store directives up-to-date
63    o Really weird thing!
64      call do_the_model_io from the_main_loop with parameters
65      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
66      TAF places a faulty re-call of initialise_varia
67      after cost_final call which should not be there!
68    checkpoint52j_pre
69    
70    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
71      error messages
72    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
73    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
74      debug output
75    o modfied mdsio_writefield.F to handle non-global files under exch2
76    o update AIM Cubed-Sphere exp (aim.5l_cs):
77      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
78    o update AIM Equatorial Channel exp:
79      use standard aim_v23 pkg and change the SST fields to be more realistic.
80    o globalFile now works with exch2
81    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
82      mon_vort3.F to make exch2 friendly with >1 tile per cube face
83    o limit timeave output for hi-res integrations
84    
85    checkpoint52i_post
86    o removed CPP_EEOPTIONS.h from verification/*/code
87    o updated the tiling for global_ocean_pressure
88    checkpoint52i_pre
89    
90    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
91      the old pkg/aim).
92    
93    checkpoint52h_pre
94    o shortened offending lines in exch2_send_rx?.template
95    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
96    o genmake2: add build & execute test for NetCDF code
97    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
98      old grid files, moved CPP_EEMACROS.h to pkg/exch2
99    o added useSingleCPUIO flag to monitor.F and mon_out.F
100    o added temporary hack for sea-ice dynamics on the cube:
101      metric terms are ignored and it is assumed that
102      there is no sea-ice on cube faces 1, 2, 4, and 5.
103    
104    checkpoint52f_post
105    o added exch2 cube routines to pkg/exch2
106    o modified hs94.cs-32x32x5 to use it
107    o added new grid files to hs94.cs-32x32x5
108    checkpoint52f_pre
109    
110    checkpoint52e_post
111    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
112      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
113    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
114      to work with implicit vertical advection and AB ;
115    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
116    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
117     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
118    checkpoint52e_pre
119    
120    o fix bug in impldiff when Nr=1 or Nr=2.
121    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
122    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
123    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
124      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
125    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
126    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024

128    
129    checkpoint52d_post
130    o re-tiled many expts to allow comparison in multi-processor mode
131      - updated output accordingly
132      - changed hs94.128x64x5 to use intial T from file rather than use the
133        random number generator
134    o add infrastructure in model routines for fizhi and gridalt packages
135    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
136    o changes to permit hi-res, cubed-sphere, configuration
137      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
138      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
139      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
140        of surface winds for the cube
141      (A verification experiment, based on global_ocean.cs32x15, but with
142       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
143       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
144       complete with example surface forcing files and matlab scripts to look
145       at the output and compare it with that of global_ocean.cs32x15.)
146    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
147       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
148       to conform to the common rule.
149    o check-in the first version of the coupler + interfaces for multi-components
150       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
151       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
152       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
153       - ocean and atmos. share the same horizontal grid (no interpolation).
154       - exchanges between component and coupler is done in forward_step
155    o new verification experiment, cpl_aim+ocn:
156       coupled ocean - AIM atmosphere on cs32 grid.
157    
158    checkpoint52d_pre
159    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
160    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
161    
162    checkpoint52c_post
163    o Fixing OPTIONS files for use of exf:
164      - ALLOW_ECCO not needed
165      - ECCO_CPPOPTIONS.h should not be included from
166        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
167        as has been the case in the past
168      - All cal/exf related options are currently set in
169        single header file. Should remain so until we
170        agree on a consistent new policy.
171    o Removed all CPP options for cal package.
172      cal has no more CPP options.
173    o modified STOREs in GAD_ADVECTION
174    o corrected key comp. for passkey
175    
176    checkpoint52b_post
177    o new version: "thsice" of thermodynamic sea-ice pkg:
178     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
179     - modify fluxes but do not change theta directly;
180     - light cleaning of bulk_force pkg (still needed with thsice).
181     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
182       + output_thsice.txt to test thsice & bulk_force pkgs.
183    o put back grid & coriolis monitor output.
184    checkpoint52b_pre
185    
186    o call "do_the_model_io" at the beginning (=> dump initial state)
187    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
188    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
189      (need info on NUMBER_OF_PTRACERS)
190    o missing PTRACERS headers in some routines
191    o default tamc.h in pkg/autodiff supposed to crash
192      to ensure proper customization
193    
194    checkpoint52a_post
195    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
196      - moved surfaceTendencyTice from pkg/seaice to main code
197      - subroutine FREEZE_SURFACE now limits only surface temperature
198        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
199        => new output.txt for global_ocean.cs32x15 & global_with_exf
200      - keep the old version of FREEZE for backward compatibility;
201        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
202      - corresponding modifs for TAF directives
203    o added surface flux output variables to TIMEAVE_STATVARS
204    o time-averaged output for pkg/ptracers
205    o fix problem with ECCO-related divided adjoint

207      but no warning issued by TAF
208    
209    checkpoint52a_pre
210    o some bug fixes for #undef REAL4_IS_SLOW
211    
212    checkpoint52 = ecco_c52_e35
213    o after testing adjoints of checkpoint51u_post
214    
215    checkpoint51u_post
216    o this is the post-merge tag of the ecco-branch
217      (needs another clean checkout and re-testing)
218    o various natl_box_adjoint configs and results
219      but no input fields
220    o obcs adjoint not yet merged!
221    o adding ECCO global 1x1 and 2x2 degree configs
222    o updated/extended some store directives for seaice
223    o pkg/ecco now containes ecco-specific part of cost function
224    o top level routines the_main_loop, forward_step
225      supersede those in model/src/
226      previous input data.cost now in data.ecco
227      (new namelist ecco_cost_nml)
228    o in ctrl/ cleaned some cross-dependencies and updated CPP options
229    
230    checkpoint51t_post
231    o this is the pre-merge tag of the ecco-branch
232    
233    checkpoint51s_post

235    o pkg/grdchk
236      - renamed 'ph-grd 3' to 'grad-res'
237      - merged from ecco-branch
238        (remaining bug fixes for obcs gradient checks)
239      - additional high-precision output for testreport
240        (grep for 'precision_grdchk_result')
241    
242    checkpoint51r_post
243    o cleaned up or removed CPP_OPTIONS.h files
244    o updated results for some of the tests to reflect the new
245      optfiles (-ieee: -O0 instead of -O3)
246    
247    checkpoint51q_post
248    o cd_code:
249      - moved cd_scheme.F -> cd_code_scheme.F
250      - separate read_checkpoint from cd_code_ini_vars.F
251      - separated cd_code part from write_checkpoint
252      - updated AD_SOURCE, generated .flow
253      - added CD_CODE_VARS.h to the_main_loop
254      - Moving cd_code specific store dir.s to pkg/cd_code
255    o ctrl package totally restructured
256      - pack/unpack now optional and decoupled from
257        xx_/adxx_ I/O
258      - ctrl_pack/unpack cleaned
259        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
260      - confined inclusion of AD_CONFIG.h to where necessary.
261    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
262    
263    checkpoint51p_post
264    o create initial cd_code package
265      - WARNING: the initialization of fields within packages
266        is broken because INI_FIELDS (where READ_CHECKPOINT is
267        called) is called *before* PACKAGES_INIT_VARIABLES.
268        This seems to be backwards since
269        1) its important to initially zero the entire field including
270           the "halo" region
271        2) zeroing needs to be done *before* reading pickup info
272           and the pickup call might or might not happen in any
273           particular run
274      - this needs an overhaul for R2
275    o cleanup verification/*/code/GMREDI_OPTIONS.h
276    o cleanup testreport
277    
278    checkpoint51o_post
279    o bringing AD-related verif's up to date with genmake2
280      - carbon/
281      - global_ocean.90x40x15/
282      - hs.94.1x64x5/
283      - (front_relax/ )
284    o (more) consistent directory structure for AD-related verif.'s
285    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
286    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
287    o bug fix in find_alpha.F for MDJWF:
288      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
289        change rho -> rho-rhoConst
290      - replace call find_rho to find_rhonum
291    o initialisation of rFlx extended to full array (required by TAF)
292      and shifted to thermodynamics
293    o removed PTRACERS.h in ptracers routine
294    o added surfacetendencyPtr to S/R parameter list pracers_forcing
295    o Correcting initialisations for fVerU, fVerV.
296    o helping TAF to recognize dependency on kUp for

308    o modifications to make FREEZE flux visible to pkg/kpp
309      - moved surfaceTendencyTice from pkg/seaice to main code
310      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
311      - subroutine FREEZE now limits only surface temperature
312        (this means new output.txt for global_ocean.90x40x15,
313         global_ocean.cs32x15, and global_with_exf)
314    o added surface flux output variables to TIMEAVE_STATVARS
315    
316    checkpoint51n_pre
317    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
318    o added [#include "AD_CONFIG.h"] to all files that use the following
319      defines:

337    checkpoint51l_pre
338    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
339    o enable to apply restoring on S & T only in a latitude band.
340    o update output (external_forcing_surf modif. change truncation errors)
341       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
342    
343    checkpoint51k_post
344    o change default to: useNHMTerms=.FALSE.
345     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
346       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5

369           - pkg_ad_check_lev?_dir.h
370    
371    checkpoint51i_post
372    o merge of the branch-genmake2
373      - knowingly breaks the older genmake

423    
424    checkpoint51d_post
425    o change function ILNBLNK (=> last non-blank char.) to return zero

427    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
428    o modif's to restore TAMC compatibility
429      - avoid "_d" constructs in PARAMETER declarations
430      - avoid interrupting lines by comment lines
431    o Use cluster local disks for purely local I/O
432      vs. globally visible disks needed for ctrl stuff
433      (merged from ecco-branch)
434      - new active_file_loc... and mdsio_..._loc routines
435      - affected packages: autodiff, ctrl, grdchk, mdsio
436    
437    checkpoint51c_post
438    o introducing integer flag debugLevel
439      - debLevZero: suppress all output
440      - debLevA: standard
441      - debLevB: equivalent to current debugMode=.TRUE.
442    o introducing pathname variable mdsioLocalDir for mdsio
443      that can be specified at runtime
444      (relevant for cluster I/O to local disk)
445    `
446    >>>checkpoint51b_post
447    adjoint of ptracers
448    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
449    o extended state in checkpoint_lev?, etc.

452    o new ptracers.flow
453    o made ptracers_forcing same as external_forcing_s
454    o added verification for adjoint with ptracers
455      - adm. grdchk fail so far
456      - tlm. grdchk OK
457      - checked tapelev/comlev recomputations: OK
458    <<<checkpoint51b_pre
459    
460    checkpoint51a_post
461    o added code for biogeochemistry package
462      - new pkgs: dic, gchem
463      - new subroutine in ptracers
464    o modify code for biogeo packages
465      - in model/src and pkg/ptracers
466    
467    checkpoint51
468    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
469      - autodiff, ctrl, exf, grdchk, seaice
470      kept separate packages
471      - cost, ecco, obcs
472    o updating verification/internal_wave, verification/lab_sea
473      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
474    
475    checkpoint50i_post
476    o Preparing next differentiable checkpoint and sync
477      of MAIN vs. ecco-branch
478      - 1st step: this one is differentiable
479      - 2nd step: next(! not this) checkpoint will have updated packages
480                  from ecco-branch)
481    
482    checkpoint50h_post
483    o new package "land": provide surface BC for AIM.
484    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
485    o AIM: use true log-P extrapolation for near surface temp (= as in
486        F.Molteni paper) ; update aim.5l_cs output.
487    o New variable in PARM03 for more flexible pickups
488    o somewhat cleaned package initialisation sequence for
489      ctrl/ cost/ ecco/ in packages_... routines
490    
491    checkpoint50g_post
492    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
493      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
494      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
495        made the default because of faster convergence than ADI
496    
497    checkpoint50f_post
498    o exf totally restructured
499      - replaced all exf_set_ routines by one generic exf_set_gen.F
500        and made sure it's still differentiable
501      - split exf_getffields.F into new exf_bulkformulae.F
502      - exf_inscal_/exf_outscal_ suffixes consistent with field names

507          + change Evap over land. (update aim.5l_cs output)
508     o added missing .cvsignores and made uniform across expts
509     o changed configuration of tidal_basin_2d expt
510     o added pkg/debug functions for tracing code in fatal crashes

512     o new fn in pkg/monitor to stop model if solution grows too big
513     o removed lots of single quotes from comments
514    
515    checkpoint50e_post
516    o make KPP work with PTRACERS
517     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
518       nearly a copy of kpp_transport_s
519     - there is no analogue to SurfaceTendencyS, so I have to use
520       gPtr(of the surface layer) instead
521    o add a new platform SunFire+mpi (SunFire 15000) to genmake
522    checkpoint50e_pre
523    
524    checkpoint50d_post
525    o change kpp output from multiple-record state files to single-record state
526      files analogous to write_state.F
527    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
528      analogous to the cg2d-related output.
529    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
530      so that writing to internal file fn (with length 512) fails.
531    checkpoint50d_pre
532    
533    checkpoint50c_post
534    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
535    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
536    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
537    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
538    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
539    
540    checkpoint50c_pre
541    Merging from release1_p13:
542    o bug fix for pkg/seaice dynamic solver
543    o Added SEAICE_initialHEFF to pkg/seaice
544    
545    checkpoint50b_post
546    o store u*,v* in gU,V instead of in guNm1,gvNm1
547    o in order to put the momForcing out of the Adams-Bashforth:
548      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
549      to timestep.F
550    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
551    o re-generate output for highly sensitive test-exp:
552       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
553    
554    checkpoint50b_pre
555    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
556    o corrected CPP option mismatch in exf_Bulk... functions for case
557      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
558    
559    checkpoint50a_post
560    o Bug fix for merging between c50 and KPP.
561      ikey was passed from thermodynamics to kpp_calc via
562      common block rather than being recomputed in kpp_calc,
563      in contradiction with new key itdkey.
564      New key ikppkey created, and tamc.h headers updated.
565    
566    checkpoint50
567    - 2nd step of merge with ecco-branch:
568      merge changes in ecco-branch back into main trunk
569    - bug fix in find_alpha
570    - more storing in gmredi_calc_tensor.F, kpp_routines.F
571    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
572    - merged some sliced AD support routines
573    
574    checkpoint49
575    merged from ecco-branch:
576    o exf:
577      - Enable initialisation of forcing fields to constant
578        (runtime) values.
579      - in exf_getffields.F
580        Reduce i-/j-loop to interior domain, discarding overlaps.
581        That also fixes wrong TAF-key computations for key_1, key_2
582        with bulf formulae.
583      - exf_init.F modify #ifdef for exf_init_evap
584      - exf_getffieldrec.F, ctrl_getrec.F
585        The following INT-usages are not safe:
586          fldsecs  = int(fldsecs/fldperiod)*fldperiod
587          fldcount = int(fldsecs/fldperiod) + 1
588        and were modified.
589    o autodiff: checkpoint_lev...
590      - updated storing for bulk formulae (some arrays were missing)
591      - added state for seaice package
592      - synchronized with main branch
593    o DIVA:
594      Modif.s in
595      - the_main_loop.F
596      - the_model_main.F
597      and added cost_final_restore.F cost_final_store.F
598      o With these changes, it is possible to fully separate
599        the first forward run to compute the cost function (mdthe_main_loop)
600        and adjoint runs over individual DIVA intervals (adthe_main_loop)
601        into separate model executions.
602        This enables better tuning of DIVA to given queue sizes.
603      o Loss of cost function value in consecutive DIVA runs is
604        fixed by storing to 'costfinal' file.
605      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
606        beginning/end of adjoint integration is accounted for.
607      The current changes apply to TAF-1.4.26.
608      TAF has one remaining bug, requiring one manual change
609      (see MITgcm manual).
610    o cal: synchronized between MAIN and ecco-branch
611    
612    checkpoint48i_post
613    o Changes to restore differentiability of code w.r.t. previous tag
614      (mostly adding new routines to make list and replacing
615      pressure by totPhiHyd).
616    o Updated and merged grdchk package
617      - has both ADM and TLM checks
618      - works for single- and multi-proc.
619      - output cleaned
620      - worked successfully for parallel DIVA
621    o genmake:
622      - Adding -platform=SP4
623      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
624    o Modif. for DIVA:
625      ctrl_unpack should not be called in intermediate DIVA interval.
626      (similar thing would apply for active files such as
627      tbar, sbar, psbar, which should not be reinitialised;
628      only relevant for ecco-branch)
629    
630    checkpoint48h_post
631  o improve "ini_p_ground" when using finite difference form for calc_phi_hyd  o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
632  o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F  o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
633  o Added SEAICE_initialHEFF to pkg/seaice  o Added SEAICE_initialHEFF to pkg/seaice
634    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
