3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o added printMapIncludesZeros to EEPARMS namelist
7    
8    checkpoint53a_post
9    o restore TAMC compatiility for exf_constants.h
10      (no usage of _d in .h)
11    o Additional storing in KPP in an attempt to fix
12      TAMC problem with adjoint of KPP code.
13      (no success...)
14      Identical code works fine with TAF.
15    o Fixed verification/natl_box_adjoint experiments.
16      Initial conditions for Experiments 4 and 5 are now
17      set to "SEAICE_initialHEFF=0", which is more reasonable,
18      and hence gives results closer to that of Experiment 2.
19      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
20    
21    checkpoint53
22    o stable checkpoint with up to date adjoint
23      TLM tests only run for 1st grdchk at the moment. Its unclear if
24      this is a code problem or a problem with resetting code for g_
25      variables that is being autogenerated wrong.
26      Otherwise:
27       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
28       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
29         are both still in chaos following their security messes.
30    
31    checkpoint52n_post
32    o various build (mostly genmake2) changes including:
33      - ability to build/run more easily within Cygwin and MacOS X
34      - more complicated Makefiles with a stronger dependence on Gnu Make
35    o pkg/seaice modifications
36      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
37        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
38        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
39      - changed proxy for geostrophic velocity and updated
40        verification/lab_sea/results/* accordingly
41      - removed ADI dynamic solver from pkg/seaice
42      - replaced all occurrences of 1/CSTICE or 1/CSUICE
43        they caused a segmentation fault under certain circumstances
44      - removed unused field WATR
45    o bug fix in exf-package:
46      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
47         now reflect that.
48    o small fixes in the cal-package:
49      - set reference date to first of January for the 'model'-calendar
50      - failing of cal_CheckDate in cal_FullDate now actually results in a
51        warning
52    o small modifications in exf-package to increase flexibility:
53      - change climtempfreeze from a constant to a runtime parameter that
54        is specified in data.exf_clim (default = -1.9)
55      - introduce runtime parameter windstressmax (default = 2.0) that is
56        specified in data.exf
57    o fix in pkg/thsice:
58      - update Evap (Tsf changes) to be consistent with Latent heat flux
59      - maintain snow precipitation unchanged (even if Tsf >=0).
60     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
61    
62    checkpoint52m_post
63    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
64      this does not change any of the results, because myIter=0 in swfrac always
65      lead to jwtype=2 (the default anyway), but the call makes little sense
66      as a default
67    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
68    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
69      atmospheric model (AIM) to use it ; add a "slab ocean" component.
70    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
71    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
72    o extending useSingleCpuIO option to work with new exch2 I/O format
73      - old-style, missing-tile I/O is still accessible by defining CPP
74        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
75    o monitor package can write to NetCDF files and/or STDOUT
76    o fix re-definition bug in MNC_GRID_INIT_ALL()
77    o doc/api_reference added
78      - a framework for building an API Reference Manual using all
79        the "protex" comments embedded in the code
80      - see pkg/generic_advdiff, pkg/mnc for examples
81    o MNC:
82      - make myThid the last argument for all subroutines
83      - new default for the grid files: NO halos
84      - add useMNC and other run-time flags
85      - separate per-file-group handling of the unlimited dimension
86      - early initialization of MNC w/ flags read at the eeboot stage
87        and lookup tables set in initialize_fixed
88      - write all MNC output to a freshly-created directory
89    o thermodynamics sea-ice (thsice) is now tested with testreport.
90    o test exp. advect_cs: use the standard cs32 grid ; update output.
91    o Added functionality to grdchk:
92      pick global i,j,k position (or nearest wet) where to perform check.
93    
94    checkpoint52l_post
95    o new land formulation:
96      a) use ground enthalpy as prognostic variable to ensure exact
97         energy conservation.
98      b) account for water temperature and for latent heat of freezing
99         in all processes (rain, run-off, ground storage)
100      c) compute surface and ground temperature implicitly.
101    o aim_v23 modification for new land model:
102      a) Treat separately land / ocean / sea-ice surface fluxes
103         to allow implicit computation of land & sea-ice surface temp.
104      b) add snow precipitation.
105    checkpoint52l_pre
106    
107    o fix problem (when 1 tile is empty) in min/max monitor.
108    o fix bug in timeAve (u,vZetatave in common block)
109    o no restoring terms under ice for pkg/seaice
110    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
111    o bug fix for pkg/seaice pickups
112    o change MNC call locations and add coordinate attributes
113    o mask vorticity at the corner ; affects global_ocean.cs output
114    o fix ini_curvilinear_grid ; test CS experiments with mpi
115    o aim.5l_cs: modify sea-ice fraction input file ; update output
116    o exf: Adding simple range check routine for exf fields after read
117    
118    checkpoint52k_post
119    o removed top-level directory "diags"
120      - we migrated these functions to pkg/timeave a long time ago
121    o fixed bug introduced in pkg/monitor
122    o accuracy ctrlprec = 32 insuffient for gradient checks using
123      averaged fields (I/O via cost_averages)
124      -> use ctrl.h in active_file*.F to control I/O precision.
125    o paramter list of CALL ADTHE_MAIN_LOOP
126    o added initial do_the_model_io to ecco
127    o set all ...Freq to zero after cost_final
128      taveFreq, dumpFreq, pChkptFreq
129    o MAIN and ECCO differentiability restored
130    
131    checkpoint52j_post
132    o fix nchklev in tamc.h for global_ocean...
133    o Bringing flow and store directives up-to-date
134    o Really weird thing!
135      call do_the_model_io from the_main_loop with parameters
136      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
137      TAF places a faulty re-call of initialise_varia
138      after cost_final call which should not be there!
139    checkpoint52j_pre
140    
141    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
142      error messages
143    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
144    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
145      debug output
146    o modfied mdsio_writefield.F to handle non-global files under exch2
147    o update AIM Cubed-Sphere exp (aim.5l_cs):
148      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
149    o update AIM Equatorial Channel exp:
150      use standard aim_v23 pkg and change the SST fields to be more realistic.
151    o globalFile now works with exch2
152    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
153      mon_vort3.F to make exch2 friendly with >1 tile per cube face
154    o limit timeave output for hi-res integrations
155    
156    checkpoint52i_post
157    o removed CPP_EEOPTIONS.h from verification/*/code
158    o updated the tiling for global_ocean_pressure
159    checkpoint52i_pre
160    
161    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
162      the old pkg/aim).
163    
164    checkpoint52h_pre
165    o shortened offending lines in exch2_send_rx?.template
166    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
167    o genmake2: add build & execute test for NetCDF code
168    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
169      old grid files, moved CPP_EEMACROS.h to pkg/exch2
170    o added useSingleCPUIO flag to monitor.F and mon_out.F
171    o added temporary hack for sea-ice dynamics on the cube:
172      metric terms are ignored and it is assumed that
173      there is no sea-ice on cube faces 1, 2, 4, and 5.
174    
175    checkpoint52f_post
176    o added exch2 cube routines to pkg/exch2
177    o modified hs94.cs-32x32x5 to use it
178    o added new grid files to hs94.cs-32x32x5
179    checkpoint52f_pre
180    
181    checkpoint52e_post
182    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
183      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
184    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
185      to work with implicit vertical advection and AB ;
186    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
187    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
188     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
189    checkpoint52e_pre
190    
191    o fix bug in impldiff when Nr=1 or Nr=2.
192    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
193    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
194    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
195      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
196    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
197    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
198    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
199    
200    checkpoint52d_post
201    o re-tiled many expts to allow comparison in multi-processor mode
202      - updated output accordingly
203      - changed hs94.128x64x5 to use intial T from file rather than use the
204        random number generator
205    o add infrastructure in model routines for fizhi and gridalt packages
206    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
207    o changes to permit hi-res, cubed-sphere, configuration
208      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
209      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
210      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
211        of surface winds for the cube
212      (A verification experiment, based on global_ocean.cs32x15, but with
213       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
214       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
215       complete with example surface forcing files and matlab scripts to look
216       at the output and compare it with that of global_ocean.cs32x15.)
217    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
218       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
219       to conform to the common rule.
220    o check-in the first version of the coupler + interfaces for multi-components
221       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
222       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
223       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
224       - ocean and atmos. share the same horizontal grid (no interpolation).
225       - exchanges between component and coupler is done in forward_step
226    o new verification experiment, cpl_aim+ocn:
227       coupled ocean - AIM atmosphere on cs32 grid.
228    
229    checkpoint52d_pre
230    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
231    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
232    
233    checkpoint52c_post
234    o Fixing OPTIONS files for use of exf:
235      - ALLOW_ECCO not needed
236      - ECCO_CPPOPTIONS.h should not be included from
237        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
238        as has been the case in the past
239      - All cal/exf related options are currently set in
240        single header file. Should remain so until we
241        agree on a consistent new policy.
242    o Removed all CPP options for cal package.
243      cal has no more CPP options.
244    o modified STOREs in GAD_ADVECTION
245    o corrected key comp. for passkey
246    
247    checkpoint52b_post
248    o new version: "thsice" of thermodynamic sea-ice pkg:
249     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
250     - modify fluxes but do not change theta directly;
251     - light cleaning of bulk_force pkg (still needed with thsice).
252     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
253       + output_thsice.txt to test thsice & bulk_force pkgs.
254    o put back grid & coriolis monitor output.
255    checkpoint52b_pre
256    
257    o call "do_the_model_io" at the beginning (=> dump initial state)
258    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
259    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
260      (need info on NUMBER_OF_PTRACERS)
261    o missing PTRACERS headers in some routines
262    o default tamc.h in pkg/autodiff supposed to crash
263      to ensure proper customization
264    
265    checkpoint52a_post
266    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
267      - moved surfaceTendencyTice from pkg/seaice to main code
268      - subroutine FREEZE_SURFACE now limits only surface temperature
269        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
270        => new output.txt for global_ocean.cs32x15 & global_with_exf
271      - keep the old version of FREEZE for backward compatibility;
272        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
273      - corresponding modifs for TAF directives
274    o added surface flux output variables to TIMEAVE_STATVARS
275    o time-averaged output for pkg/ptracers
276    o fix problem with ECCO-related divided adjoint
277      snapshot file was missing some ad-variables,
278      but no warning issued by TAF
279    
280    checkpoint52a_pre
281    o some bug fixes for #undef REAL4_IS_SLOW
282    
283    checkpoint52 = ecco_c52_e35
284    o after testing adjoints of checkpoint51u_post
285    
286    checkpoint51u_post
287    o this is the post-merge tag of the ecco-branch
288      (needs another clean checkout and re-testing)
289    o various natl_box_adjoint configs and results
290      but no input fields
291    o obcs adjoint not yet merged!
292    o adding ECCO global 1x1 and 2x2 degree configs
293    o updated/extended some store directives for seaice
294    o pkg/ecco now containes ecco-specific part of cost function
295    o top level routines the_main_loop, forward_step
296      supersede those in model/src/
297      previous input data.cost now in data.ecco
298      (new namelist ecco_cost_nml)
299    o in ctrl/ cleaned some cross-dependencies and updated CPP options
300    
301    checkpoint51t_post
302    o this is the pre-merge tag of the ecco-branch
303    
304    checkpoint51s_post
305    o cleanup: removed various obsolete #define-s
306    o pkg/grdchk
307      - renamed 'ph-grd 3' to 'grad-res'
308      - merged from ecco-branch
309        (remaining bug fixes for obcs gradient checks)
310      - additional high-precision output for testreport
311        (grep for 'precision_grdchk_result')
312    
313    checkpoint51r_post
314    o cleaned up or removed CPP_OPTIONS.h files
315    o updated results for some of the tests to reflect the new
316      optfiles (-ieee: -O0 instead of -O3)
317    
318    checkpoint51q_post
319    o cd_code:
320      - moved cd_scheme.F -> cd_code_scheme.F
321      - separate read_checkpoint from cd_code_ini_vars.F
322      - separated cd_code part from write_checkpoint
323      - updated AD_SOURCE, generated .flow
324      - added CD_CODE_VARS.h to the_main_loop
325      - Moving cd_code specific store dir.s to pkg/cd_code
326    o ctrl package totally restructured
327      - pack/unpack now optional and decoupled from
328        xx_/adxx_ I/O
329      - ctrl_pack/unpack cleaned
330        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
331      - confined inclusion of AD_CONFIG.h to where necessary.
332    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
333    
334    checkpoint51p_post
335    o create initial cd_code package
336      - WARNING: the initialization of fields within packages
337        is broken because INI_FIELDS (where READ_CHECKPOINT is
338        called) is called *before* PACKAGES_INIT_VARIABLES.
339        This seems to be backwards since
340        1) its important to initially zero the entire field including
341           the "halo" region
342        2) zeroing needs to be done *before* reading pickup info
343           and the pickup call might or might not happen in any
344           particular run
345      - this needs an overhaul for R2
346    o cleanup verification/*/code/GMREDI_OPTIONS.h
347    o cleanup testreport
348    
349    checkpoint51o_post
350    o bringing AD-related verif's up to date with genmake2
351      - carbon/
352      - global_ocean.90x40x15/
353      - hs.94.1x64x5/
354      - (front_relax/ )
355    o (more) consistent directory structure for AD-related verif.'s
356    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
357    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
358    o bug fix in find_alpha.F for MDJWF:
359      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
360        change rho -> rho-rhoConst
361      - replace call find_rho to find_rhonum
362    o initialisation of rFlx extended to full array (required by TAF)
363      and shifted to thermodynamics
364    o removed PTRACERS.h in ptracers routine
365    o added surfacetendencyPtr to S/R parameter list pracers_forcing
366    o Correcting initialisations for fVerU, fVerV.
367    o helping TAF to recognize dependency on kUp for
368      fVerU, fVerV
369    o Replacing delZ by delR in pkg/ctrl/
370    checkpoint51o_pre
371    
372    o undid all of cp51 pending some cleanups and discussion
373    o added the [#include "AD_CONFIG.h"] statement to all files that need
374       it for adjoint/tl #defines
375     o re-worked the build logic in genmake2 to support AD_CONFIG.h
376     o removed tools/genmake since it no longer works
377    
378    checkpoint51n_post
379    o modifications to make FREEZE flux visible to pkg/kpp
380      - moved surfaceTendencyTice from pkg/seaice to main code
381      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
382      - subroutine FREEZE now limits only surface temperature
383        (this means new output.txt for global_ocean.90x40x15,
384         global_ocean.cs32x15, and global_with_exf)
385    o added surface flux output variables to TIMEAVE_STATVARS
386    
387    checkpoint51n_pre
388    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
389    o added [#include "AD_CONFIG.h"] to all files that use the following
390      defines:
391      - ALLOW_ADJOINT_RUN
392      - ALLOW_TANGENTLINEAR_RUN
393      - ALLOW_ECCO_OPTIMIZATION
394    
395    checkpoint51m_post
396    o incorporating changes to get TAMC/TAF working in genmake2
397      - added new TAMC/TAF targets to the Makefile
398      - various cleanups related to package handling
399      - these changes should have no impact on the forward model
400    
401    checkpoint51l_post
402    o changes to pkg/cal and pkg/exf that allow and speed-up long integrations
403     - faster algorithm for cal_addtime.F
404     - higher precision arithmetic, where needed
405     - pkg/exf *startdate variables changed from calendar date to
406       model integration time
407

423      (and change sign: back to "logical" value: +1 when R increases downward)
424    o added an include barrier to the default CPP_OPTIONS.h and
425      removed the #include "PACKAGES_CONFIG.h" from it
426    o fix a bug in mom_fluxform (from chk51j_post)

474    o Added on-the-fly spatial interpolation capability
475        "USE_EXF_INTERPOLATION" to pkg/exf.
476      - This is a temporary Cartesian-grid hack until
477        the super-duper ESMF coupler becomes available.
478      - See verification/global_with_exf/README for usage example.
479      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

506      - affected packages: autodiff, ctrl, grdchk, mdsio
507    
508    checkpoint51c_post
509    o introducing integer flag debugLevel
510      - debLevZero: suppress all output
511      - debLevA: standard
512      - debLevB: equivalent to current debugMode=.TRUE.
513    o introducing pathname variable mdsioLocalDir for mdsio
514      that can be specified at runtime
515      (relevant for cluster I/O to local disk)
516    `
517    >>>checkpoint51b_post
518    adjoint of ptracers
519    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM

533      - new pkgs: dic, gchem
534      - new subroutine in ptracers
535    o modify code for biogeo packages
536      - in model/src and pkg/ptracers
537    
538    checkpoint51
539    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
540      - autodiff, ctrl, exf, grdchk, seaice
541      kept separate packages
542      - cost, ecco, obcs
543    o updating verification/internal_wave, verification/lab_sea
544      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
545    
546    checkpoint50i_post
547    o Preparing next differentiable checkpoint and sync
548      of MAIN vs. ecco-branch
549      - 1st step: this one is differentiable
550      - 2nd step: next(! not this) checkpoint will have updated packages
551                  from ecco-branch)
552    
553    checkpoint50h_post
554    o new package "land": provide surface BC for AIM.
555    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
556    o AIM: use true log-P extrapolation for near surface temp (= as in
557        F.Molteni paper) ; update aim.5l_cs output.
558    o New variable in PARM03 for more flexible pickups
559    o somewhat cleaned package initialisation sequence for
560      ctrl/ cost/ ecco/ in packages_... routines
561    
562    checkpoint50g_post
563    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
564      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
565      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
566        made the default because of faster convergence than ADI
567    
568    checkpoint50f_post
569    o exf totally restructured
570      - replaced all exf_set_ routines by one generic exf_set_gen.F
571        and made sure it's still differentiable
572      - split exf_getffields.F into new exf_bulkformulae.F

584     o removed lots of single quotes from comments
585    
586    checkpoint50e_post
587    o make KPP work with PTRACERS
588     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
589       nearly a copy of kpp_transport_s
590     - there is no analogue to SurfaceTendencyS, so I have to use
591       gPtr(of the surface layer) instead
592    o add a new platform SunFire+mpi (SunFire 15000) to genmake
593    checkpoint50e_pre
594    
595    checkpoint50d_post
596    o change kpp output from multiple-record state files to single-record state
597      files analogous to write_state.F
598    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
599      analogous to the cg2d-related output.
600    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
601      so that writing to internal file fn (with length 512) fails.
602    checkpoint50d_pre
603    
604    checkpoint50c_post
605    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
606    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
607    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
608    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
609    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
610    
611    checkpoint50c_pre
612    Merging from release1_p13:
613    o bug fix for pkg/seaice dynamic solver
614    o Added SEAICE_initialHEFF to pkg/seaice
615    
616    checkpoint50b_post
617    o store u*,v* in gU,V instead of in guNm1,gvNm1
618    o in order to put the momForcing out of the Adams-Bashforth:
619      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
620      to timestep.F
621    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
622    o re-generate output for highly sensitive test-exp:
623       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
624    
625    checkpoint50b_pre
626    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
627    o corrected CPP option mismatch in exf_Bulk... functions for case
628      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
629    
630    checkpoint50a_post
631    o Bug fix for merging between c50 and KPP.
632      ikey was passed from thermodynamics to kpp_calc via
633      common block rather than being recomputed in kpp_calc,
634      in contradiction with new key itdkey.
635      New key ikppkey created, and tamc.h headers updated.
636    
637    checkpoint50
638    - 2nd step of merge with ecco-branch:
639      merge changes in ecco-branch back into main trunk
640    - bug fix in find_alpha
641    - more storing in gmredi_calc_tensor.F, kpp_routines.F
642    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
643    - merged some sliced AD support routines
644    
645    checkpoint49
646    merged from ecco-branch:
647    o exf:
648      - Enable initialisation of forcing fields to constant
649        (runtime) values.
650      - in exf_getffields.F
651        Reduce i-/j-loop to interior domain, discarding overlaps.
652        That also fixes wrong TAF-key computations for key_1, key_2
653        with bulf formulae.
654      - exf_init.F modify #ifdef for exf_init_evap
655      - exf_getffieldrec.F, ctrl_getrec.F
656        The following INT-usages are not safe:
657          fldsecs  = int(fldsecs/fldperiod)*fldperiod
658          fldcount = int(fldsecs/fldperiod) + 1
659        and were modified.
660    o autodiff: checkpoint_lev...
661      - updated storing for bulk formulae (some arrays were missing)
662      - added state for seaice package
663      - synchronized with main branch
664    o DIVA:
665      Modif.s in
666      - the_main_loop.F
667      - the_model_main.F
668      and added cost_final_restore.F cost_final_store.F
669      o With these changes, it is possible to fully separate
670        the first forward run to compute the cost function (mdthe_main_loop)
671        and adjoint runs over individual DIVA intervals (adthe_main_loop)
672        into separate model executions.
673        This enables better tuning of DIVA to given queue sizes.
674      o Loss of cost function value in consecutive DIVA runs is
675        fixed by storing to 'costfinal' file.
676      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
677        beginning/end of adjoint integration is accounted for.
678      The current changes apply to TAF-1.4.26.
679      TAF has one remaining bug, requiring one manual change
680      (see MITgcm manual).
681    o cal: synchronized between MAIN and ecco-branch
682    
683    checkpoint48i_post
684    o Changes to restore differentiability of code w.r.t. previous tag
685      (mostly adding new routines to make list and replacing
686      pressure by totPhiHyd).
687    o Updated and merged grdchk package
688      - has both ADM and TLM checks
689      - works for single- and multi-proc.
690      - output cleaned
691      - worked successfully for parallel DIVA
692    o genmake:
693      - Adding -platform=SP4
694      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
695    o Modif. for DIVA:
696      ctrl_unpack should not be called in intermediate DIVA interval.
697      (similar thing would apply for active files such as
698      tbar, sbar, psbar, which should not be reinitialised;
699      only relevant for ecco-branch)
700    
701    checkpoint48h_post
702    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
703    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
704    o Added SEAICE_initialHEFF to pkg/seaice
705    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
706    
707    checkpoint48g_post
708    --- EOS:
709    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
710      store total Potential in totPhyHyd for diagnostics & EOS.
711    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
712    --- Pressure/geopotential gradient:
713    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
714    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
715      ( changes results of global_ocean_pressure )
716    o NLFS + z-coord.: add eta*Rho' contribution.
717    o accurate phiHyd when using interface-W at the middle between 2 centers
718     ( changes results of ideal_2D_oce )
719    o includes r* 2nd term in potential gradient.
720    
721    checkpoint48f_post
722    Merging from release1_p12:

729      (SBO) core products, including oceanic mass, center-of-mass,
730      angular, and bottom pressure (see pkg/sbo/README.sbo).
731    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
732      to avoid negative values in shallow regions.
733      - updated verification/natl_box/results/output.txt
734      - updated verification/lab_sea/results/output.txt
735    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
736    o Added useSingleCpuIO option (see PARAMS.h).
737    o Updated useSingleCpuIO option in mdsio_writefield.F to
738      work with multi-field files, e.g., for single-file pickup.
739    o pkg/seaice:
740      - bug fix in growth.F: QNET for no shortwave case
741      - added HeffFile for specifying initial sea-ice thickness
742      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
743    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
744      kpp_transport_t.F, forward_step.F, and the_main_loop.F
745    o pkg/seaice:
746      - adjoint-friendly modifications
747      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F

749    checkpoint48e_post
750    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
751    o dynamics: change definition of computational domain & adapt mom_fluxform
752      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
753    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
754        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
755        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
756        global_ocean.90x40x15 global_with_exf global_ocean_pressure
757        inverted_barometer solid-body.cs-32x32x1
758      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
759    
760    checkpoint48d_post
761    o in preparation for r*:
762     a) use pre-computed gradient of hydrostatic potential:
763        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
764     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
765        => affects results of glob_oce_pressure (different truncation error)  
766      update output.txt of ideal_2D_oce & global_ocean_pressure
767    
768    checkpoint48d_pre
769    o in preparation for r*:
770      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
771      pass the 2 comp. of the grad. as arguments to momentum S/R.
772      but for the moment, only used if it does not change the results.
773    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
774    
775    checkpoint48c_post
776    Modifications in treatment of initial flux forcing controls
777    to avoid extra storing of flux fields.
778    
779    checkpoint48c_pre
780    o Added tidal_basin_2d experiment (currently 1D!)
781    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
782    
783    checkpoint48b_post
784    o r* coordinate added in #ifdef NONLIN_FRSURF block.
785     (modification to pressure gradient not yet implemented)
786    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
787      (for U & V) that are used for vertical advection of momentum.
788    
789    checkpoint48a_post
790    o In preparation for r*, use temp. array to compute vertical transport
791       in flux-form momentum pkg. => change results of few test-exp.
792      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
793                        lab_sea, natl_box & plume_on_slope
794    
795    checkpoint48
796    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
797    
798    checkpoint47j_post
799    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
800    o moved adexch from forward_step to addummy_in_stepping
801    o added exch in ctrl_map_...
802    o aveFreq.=0. at end of cost_final to avoid overwrite in
803      reverse checkpointing loop
804    o Yet more changes in gmredi:
805      * adgmredi_calc_tensor
806        avoiding all recomputation of gmredi_slope_limit
807      * adgmredi_x/y/rtransport
808        added flag for excessive storing to avoid recomp. of
809        u/v/rtans, dTdx/y/z
810        -> this is not really necessary and very memory-consuming
811      * adgmredi_slope_psi:
812        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
813      * gmredi_slope_limit
814        re-activated full calculation of taperfct for case 'ac02'
815    o updating verification/ adjoints of carbon, global_ocean.90x40x15
816    
817    checkpoint47i_post
818    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
819    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
820      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
821    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
822    o gmredi: fix few bugs.
823    
824    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
825    This will be a good checkpoint to plug into the ecco-branch.
826    o few modif.'s to get latest version adjointed
827      (mainly kick out code in ini_linear_phisurf)
828    o modif's to run adjoint with exactConserv
829    o case GM_BOLUS_ADVEC should be cleaned
830      S/R gmredi_slope_psi should be cleaned
831    o verification/carbon now has exactConserv=.TRUE.
832    
833    checkpoint47g_post
834    o time-average AIM output: becomes independent from statvars time-average
835      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
836    o After TAF bug fix:
837      Tested adjoint of gmredi package.
838      Tests were done with checkpoint47 rather than with latest
839      checkpoint47f_post since the latter is broken for the adjoint
840      verification/carbon/ contains both ADM and TLM gradient checks.
841    Here they are, before they get changed/lost/stolen.
842    Mostly modif.'s to fix numerical sensitivities.
843    Gradient checks OK for
844    - GM_taper_scheme:
845      * clipping
846      * ac02
847      * linear
848      * glw91
849      * dm95
850      * ldd97
851    - GMREDI_OPTIONS:
852      * GM_VISBECK_VARIABLE_K
853      * GM_NON_UNITY_DIAGONAL
854      * GM_EXTRA_DIAGONAL
855      * GM_BOLUS_ADVEC
856    in conjunction with data.gmredi parameters to be checked in
857    in a few minutes under verification/carbon/code/
858    
859    checkpoint47f_post
860    Merging from release1_p10:
861    o modifications for using pkg/exf with pkg/seaice
862      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
863        and SEAICE_EXTERNAL_FLUXES
864      - pkg/exf CPP options EXF_READ_EVAP and
865        EXF_NO_BULK_COMPUTATIONS
866      - usage examples are Experiments 8 and 9 in
867        verification/lab_sea/README
868      - verification/lab_sea default experiment now uses
869        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
870    
871    checkpoint47e_post
872    o created a tag prior to creating a branch
873    
874    checkpoint47d_post
875    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
876      at the bottom boundary had an erroneous half slip boundary condition
877    o added bottom drag and no slip boundary condition capabilities to
878      oceanic pressure coordinates code
879    o added new verification experiment global_ocean_pressure, this experiment is
880      also described in the tutorial section of the manual
881    checkpoint47d_pre
882    
883    checkpoint47c_post
884    o Added a verification experiment for a global cubed-sphere ocean run
885      -  verification/global_ocean.cubed32x32x30
886      -  uses pkg/therm_seaice and pkg/bulk_forcing
887    
888    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
889    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
890      when using P-coordinate; only implemented for atmospheric config.
891    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
892      NOTES: requires option NONLIN_FRSURF to be "#define".
893    o update advect_xz/results/output.txt (left from checkpoint44g_post)
894    
895    checkpoint47b_post
896    Merging from release1_p9:
897    o pkg/seaice
898      - removed GOTO's and added taf directives
899      - double precision constants to reduce the g77 (Linux)
900        to F77 (SGI) differences reported in release1_p8
901    o tools/genmake
902      - added SGI options
903    o verification/testscript
904      - updated to that of checkpoint47a_post
905    o verification/global_ocean.90x40x15/input/eedata
906      - modified for SGI f77 compatibility
907    o verification/lab_sea
908      - added description of sea-ice model
909      - added missing matlab routines
910      - added test of thermodynamics parallelization
911    
912    checkpoint47a_post
913    o new pkg: aim_v23
914     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
915       for now, keep the same surface forcing as before.
916     - Part-Cell implemented into AIM; check that Heat & Water are conserved
917     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
918     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
919    o add diagnostic of surface correction term in monitor output
920    
921    o bulk_force and therm_seaice
922    - Two packages:  bulk_force (Bulk forcing)
923      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
924    - Earlier integration from Stephaine Dutkiewicz
925      and Patrick Heimbach.
926    - Two ifdef statements for compile time,
927       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
928    
929    checkpoint47
930    differentiable version of checkpoint46n_post
931    o bug fix in quasihydrostaticterms
932    o * "clean" adjoint code (in terms of extensive recomputations)
933        can now be obtained for all GMREDI options (i.e. for
934        - GM_VISBECK_VARIABLE_K
935        - GM_NON_UNITY_DIAGONAL
936        - GM_EXTRA_DIAGONAL
937        - GM_BOLUS_ADVEC )
938      * However, wrong gradient check problem remains unsolved.
939      * New CPP options have been introduced for different
940        tapering schemes
941    o external_fields_load now part of differentiation list
942    o pressure needs multiple storing;
943      would be nice to have store_pressure at beginning or
944      end of forward_step, e.g. by having phiHyd global (5-dim.)
945      (NB: pressure is needed for certain cases in find_rho,
946      which is also invoked through convective_adjustment).
947    o recomputations in find_rho for cases
948     'JMD95'/'UNESCO' or 'MDJWF' are OK.
949    o #define ATMOSPHERIC_LOADING should be differentiable
950    o ini_forcing shifted to begining of initialise_varia
951    o Incorporating QNVS line search routines into MITgcm
952      (this is separate code, and therefore not under pkg)
953      lsopt/, optim/
954    o Updated verification/carbon/
955      - #define GM_VISBECK_VARIABLE_K
956      - GM_taper_scheme    = 'ldd97'    
957    
958    checkpoint46n_post
959    Merging from release1_p8:
960    o verification/natl_box:
961      updating new external_fields_load routine
962    o New package: pkg/seaice
963      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
964      The sea-ice code is based on Hibler (1979-1980).
965      Two sea-ice dynamic solvers, ADI and LSR, are included.
966      In addition to computing prognostic sea-ice variables and diagnosing
967      the forcing/external data fields that drive the ocean model,
968      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
969      The implied surface heat flux is then stored in variable
970      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
971      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
972      non-local transport term.  Because this call precedes model
973      thermodynamics, temperature under sea-ice may not be "exactly" at
974      the freezing point by the time theta is dumped or time-averaged.
975      N.B.: fairly large differences in accuracy occur across
976            different platforms/compilers; comparison between
977            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
978            generated output gives:
979       T           S           U           V
980      C D M    c        m  s        m  s        m  s        m  s
981      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
982      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
983      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
984    
985      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
986    o GAD:
987      - generated new common blocks to account for call of
988        same gad routines with differing traceridentities
989        (needed to modify tracerIdentity indices in GAD.h)
990      - generated separate common blocks for case useCubedSphereExchange
991        (Department of Futurology)
992      - parameter lists to gmredi_?transport: added tracerIdentity
993      - added new key indices to tamc.h
994    o external_fields_load:
995      - added this routine to TAF list
996      - needed to make some common blocks global and additional storing
997        along the same lines as exf package (checkpoint_lev?_directives.h)
998    o exf:
999      updated external forcing package
1000      - bug fixes carried over from ecco-branch
1001        (missing OBCS_OPTIONS.h in two routines)
1002      - enable easy to use "no forcing".
1003      - added exf I/O for atmospheric loading
1004      - added exf I/O for runoff data
1005      - transfered scaling between exf <-> MITgcm to exf namelist
1006    o Adding new verification experiment global_with_exf.
1007      This verification experiment is almost identical to the
1008      global_ocean.90x40x15 experiment, except that it uses
1009      the exf (and cal) package instead of the
1010      external_fields_load routine (cf README file).
1011    
1012    checkpoint46m_post
1013    o modified testscript to return -- when there are no lines of "%MON" output
1014    o added new flag "quasiHydrostatic" for QH mode
1015      and new routine quasihydrostaticterms()
1016    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1017      New routine: mom_u_coriolis_nh()
1018    o fixed sign of non-hydrostatic metric terms in u and v equations.
1019      Depend on correct sign of gravitySign.
1020    o added work.pc* to .cvsignore in aim directories using ifc
1021    o introduced flag for controllin non-hydrostatic metric terms
1022    o removed gravitySign from PARM04
1023    o switched to g77/ifc from pgf77 in aim experiments
1024    
1025    checkpoint46l_post
1026    o made convective adjustment work with pressure coordinates:
1027     - changed the direction of k-loop in convective_adjustment.F for the
1028       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1029     - adjusted the reference pressure k-index in convective_adjustment.F
1030     - adjusted the convection condition in convect.F (in analogy to
1031       calc_ivdc.F)
1032     - convective_adjustment no longer computes anything on the halos
1033     - removed the warnings about negative salinity from find_rho.F and
1034       find_alpha.F; instead the new routine look_for_neg_salinity, called
1035       at the beginning of find_rho, find_alpha, and find_beta, does a
1036       check of the entire slice, if CPP-option
1037       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1038    checkpoint46l_pre
1039    
1040    checkpoint46k_post
1041    o fixed the verification/global_ocean.90x40x15 experiment:
1042     - new bathymetry (the world according to A., JMC, and M.)
1043     - new initial fields and forcing fields (*.bin files)
1044     - new POLY3.COEFFS (for the next release one should switch to a full
1045       equation of state: JMD95P or MDJWF)
1046     - fixed several errors and redundancies in the data file
1047     - experiment uses looped cells
1048     - added matlab directory with diagnostic scripts for plotting of output
1049    
1050    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1051     - read AIM physics parameters from a file (data.aimphys)
1052     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1053    
1054    checkpoint46j_post
1055    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1056    o move wVel computation at the end of the time step, in S/R integr_continuity
1057    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1058    o update timeave pkg for wVel diagnostic.
1059    checkpoint46j_pre
1060    
1061    checkpoint46i_post
1062    o Clean up AIM package (and keep the results unchanged):
1063      include CPP_OPTION and use IMPLICT NONE in all routines ;
1064      declare all the variables _RL ; use _d 0 for all numerical constants.
1065      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1066    
1067    checkpoint46h_post
1068    o cleaned up the use of rhoNil and rhoConst.
1069      - rhoNil should only appear in the LINEAR equation of state, everywhere
1070        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1071        and the dynamical equations are all divided by rhoConst
1072    o introduced new parameter rhoConstFresh, a reference density of fresh
1073      water, to remove the fresh water flux's dependence on rhoNil. The default
1074      value is 999.8 kg/m^3
1075    o cleanup up external_forcing.F and external_forcing_surf.F
1076      - can now be used by both OCEANIC and OCEANICP
1077    checkpoint46h_pre
1078    
1079     Added code to convert surface volume flux (fresh water) into
1080     a mass flux when using P coordinates in the ocean (OCEANICP).
1081     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1082    
1083    checkpoint46g_post
1084    o Include a new diagnostic variable phiHydLow for the ocean model
1085      - in z-coordinates, it is the bottom pressure anomaly
1086      - in p-coordinates, it is the sea surface elevation
1087      - in both cases, these variable have global drift, reflecting the mass
1088        drift in z-coordinates and the volume drift in p-coordinates
1089      - included time averaging for phiHydLow, be aware of the drift!
1090    o depth-dependent computation of Bo_surf for pressure coordinates
1091      in the ocean (buoyancyRelation='OCEANICP')
1092      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1093        Theta, Salinity, and Pressure in the parameter list. This routine is
1094        presently contained in find_rho.F. This routine does not give the
1095        correct density for 'POLY3', which would be a z-dependent reference
1096        density.
1097    o cleaned up find_rho
1098      - removed obsolete 'eqn' from the parameter list.
1099    o added two new verification experiments: gop and goz
1100      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1101    checkpoint46g_pre
1102    
1103    checkpoint46f_post
1104    o Enable tangent linear (forward mode) gradient checks:
1105      - extended active file handling to g_... files
1106      - added TANGENT_SIMULATION to theSimulationMode
1107      - extended grdchk package accordingly
1108    o added tangent linear setup in verification/carbon/code_ftl
1109    o added adjoint setup in verification/front_relax/code_ad
1110    
1111    checkpoint46e_post
1112    o Added new equation of state -> MDJWF
1113      - EOS of McDougall et al., 2002, JAOT, submitted
1114      - caveat: the equation of state is only valid for a smaller (more
1115        realistic?) range of values than JMD95P/Z and UNESCO
1116      - added masks to the calculation of pressure in store_pressure
1117      - added more check values for density in check_eos (ini_eos.F), some of
1118        the old check values are out of the range of the MDJWF-eos, so don't
1119        expect perfect matches for those
1120    checkpoint46e_pre
1121    
1122    checkpoint46d_post
1123    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1124      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1125      case of pressure coordinates. eosType='JMD95Z' in
1126      combination with buoyancyRelation='OCEANICP' now causes an error.
1127    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1128      in find_alpha/beta.
1129    checkpoint46d_pre
1130    
1131    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1132      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1133    
1134    checkpoint46c_post
1135    o Changes necessary for ocean in p-coordinates
1136     -  Added new buoyancy relation = 'OCEANICP'
1137     -  Added new parameters = gravitySign (this used to be contained inside
1138        the factor dRdZ which I added when we first switched to R coordinates).
1139     X GM/Redi is not compatible (yet)
1140     X bottom drag and no-slip need to be debugged.
1141    checkpoint46c_pre
1142    
1143    checkpoint46b_post
1144    o Added new equation of state -> JMD95Z and JMD95P
1145      - EOS of Jackett and McDougall, 1995, JAOT
1146      - moved all EOS parameters into EOS.h
1147      - new routines ini_eos.F, store_pressure.F
1148    o Added UNESCO EOS, but not recommended because it requires
1149      in-situ temperature (see JMD95)
1150    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1151      unesco.f to be used with POLY3
1152    checkpoint46b_pre
1153    
1154    checkpoint46a_post
1155    o Added (atmospheric) pressure loading
1156      - new field in FFIELDS.h, etc...
1157      - new cpp flag ATMOSPHERIC_LOADING
1158    o Changed hFacC to _hFacC in calc_phi_hyd.F
1159    o Added SHORTWAVE_HEATING to some files for consistency
1160    checkpoint46a_pre
1161    
1162    checkpoint46
1163    further merges from release1_p5
1164    o new ctrl package
1165      - adopted from ECCO environment to enable optimization
1166      - added Eliassen Palm fluxes to controls
1167    o added Eliassen Palm flux controls to gradient check package
1168    o cost package
1169      - Compatible with new ctrl package
1170      - added Eliassen Palm cost hooks
1171      - modif's of existing cost functions
1172    o Adjoint-related bug fixes in kpp:
1173      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1174      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1175    o autodiff package
1176      - flow directives:
1177        + new for S/R do_the_model_io
1178        + enhanced for S/R checkpoint
1179        + new gmredi.flow
1180      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1181        disable adcommon.h/g_common.h by default.
1182      - fixed problem for adjoint of global_max
1183    o modified verification/carbon/
1184    o New setup for adjoint of global_ocean
1185    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1186    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1187    o incorporated hooks for sponge layer code (external_forcing.F)
1188    
1189    checkpoint45d_post
1190    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1191    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1192      (affects plume_on_slope "cg2d" output)
1193    o add new parameter deltaTfreesurf for free-surface time stepping
1194    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1195    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1196    o change phiMin in exp1 (to agree with documentation)
1197    o add new flags:
1198     - T,S forcing inside/outside Adams-Bashforth
1199     - turn off temp,salt advection and/or forcing
1200     - for each tracer, define internal flag for multiDimAdvection & A-B
1201    o monitor: change definition of KE to check conservation of Energy
1202    
1203    checkpoint45c_post
1204    o Removed f90 comments ("!")
1205    o Modified initialisations to enable exf package for MITgcm
1206      (without invoking ECCO_PACKAGE).
1207    o modifications to gradient check package (Martin Losch)
1208      - enable centered differences
1209      - modified format of standard output
1210    
1211    checkpoint45b_post
1212    o cleaned exchange calls in cg2d
1213    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1214    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1215      to configure barotropic setup (Martin Losch)
1216    o moved some initialisations within bi,bj loop in dynamics
1217      (TAF flow dependency)
1218    o in initialise_varia, moved call packages_init_variables
1219      before convective_adjustment_init
1220      (corresponding adjustment of TAF tape initialisation).
