3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o Added Bryan and Lewis, 1979, vertical diffusivity profile
7    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
8    o added Sadourny discretization of Coriolis
9      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
10      - re-enabled use of omega3 (useAbsVorticity)
11    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
12      vector-invarianet equations
13      - note: does *NOT* yet use same variable visc. for no-slip BC's.
14    o recoded the lateral boundary conditions for non-hydrostatic w, this time
15      hopefully without new bugs
16      - still to do: biharmonic friction for non-hydrostatic w
17    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
18    o regenerated output for global_ocean_ebm (using -ieee)
19    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
20      of mom_common/
21      - simple re-arrangement of instructions within computing loop
22    checkpoint53d_pre
23    
24    checkpoint53c_post
25    o new version of coupler for AIM+thSIce and Ocean models
26     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
27     - land: change Evaporation of snow
28     - aim with thSIce: fix bug in snow-precip.
29    o changes to calc_gw.F
30     - bug fix for w^2 term near the bottom boundary
31     - (hopefully) improve the lateral slip boundary condtions for use with
32        partial/looped cells
33      - because the bug fix changes two verification experiments anyway (exp5
34        and plume on slope), change the lateral boundary condition from half slip
35        to the value of no_slip_sides
36    o ebm package wasnt quite up to the parallel task. Fixed that.
37    o Adjoint of EBM package + verification
38      * TLM OK
39      * ADM not sufficient accuracy yet (needs further testing)
40    
41    checkpoint53b_post
42    o Commiting new energy balance model to repository
43      * package is pkg/ebm
44      * verif. is verification/global_ocean_ebm
45      * references are in ebm_driver.F
46    C      * X. Wang, P. Stone and J. Marotzke, 1999:
47    C        Global thermohaline circulation. Part I:
48    C        Sensitivity to atmospheric moisture transport.
49    C        J. Climate 12(1), 71-82
50    C      * X. Wang, P. Stone and J. Marotzke, 1999:
51    C        Global thermohaline circulation. Part II:
52    C        Sensitivity with interactive transport.
53    C        J. Climate 12(1), 83-91
54    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
55    C        Destabilization of the thermohaline circulation
56    C        by atmospheric eddy transports.
57    C        J. Climate 7(12), 1870-1882
58    o Will need long integration testing.
59    checkpoint53b_pre
60    
61    o created pkg/mom_common in preparation for variable viscosity code
62    o renamed and split ini_mnc_io
63    o pkg/land: only liquid water can diffuse or run-off
64    o AIM using land: soil wetness availability account for snow
65    o added printMapIncludesZeros to EEPARMS namelist
66    
67    checkpoint53a_post
68    o restore TAMC compatiility for exf_constants.h
69      (no usage of _d in .h)
70    o Additional storing in KPP in an attempt to fix
71      TAMC problem with adjoint of KPP code.
72      (no success...)
73      Identical code works fine with TAF.
74    o Fixed verification/natl_box_adjoint experiments.
75      Initial conditions for Experiments 4 and 5 are now
76      set to "SEAICE_initialHEFF=0", which is more reasonable,
77      and hence gives results closer to that of Experiment 2.
78      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
79    
80    checkpoint53
81    o stable checkpoint with up to date adjoint
82      TLM tests only run for 1st grdchk at the moment. Its unclear if
83      this is a code problem or a problem with resetting code for g_
84      variables that is being autogenerated wrong.
85      Otherwise:
86       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
87       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
88         are both still in chaos following their security messes.
89    
90    checkpoint52n_post
91    o various build (mostly genmake2) changes including:
92      - ability to build/run more easily within Cygwin and MacOS X
93      - more complicated Makefiles with a stronger dependence on Gnu Make
94    o pkg/seaice modifications
95      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
96        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
97        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
98      - changed proxy for geostrophic velocity and updated
99        verification/lab_sea/results/* accordingly
100      - removed ADI dynamic solver from pkg/seaice
101      - replaced all occurrences of 1/CSTICE or 1/CSUICE
102        they caused a segmentation fault under certain circumstances
103      - removed unused field WATR
104    o bug fix in exf-package:
105      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
106         now reflect that.
107    o small fixes in the cal-package:
108      - set reference date to first of January for the 'model'-calendar
109      - failing of cal_CheckDate in cal_FullDate now actually results in a
110        warning
111    o small modifications in exf-package to increase flexibility:
112      - change climtempfreeze from a constant to a runtime parameter that
113        is specified in data.exf_clim (default = -1.9)
114      - introduce runtime parameter windstressmax (default = 2.0) that is
115        specified in data.exf
116    o fix in pkg/thsice:
117      - update Evap (Tsf changes) to be consistent with Latent heat flux
118      - maintain snow precipitation unchanged (even if Tsf >=0).
119     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
120    
121    checkpoint52m_post
122    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
123      this does not change any of the results, because myIter=0 in swfrac always
124      lead to jwtype=2 (the default anyway), but the call makes little sense
125      as a default
126    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
127    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
128      atmospheric model (AIM) to use it ; add a "slab ocean" component.
129    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
130    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
131    o extending useSingleCpuIO option to work with new exch2 I/O format
132      - old-style, missing-tile I/O is still accessible by defining CPP
133        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
134    o monitor package can write to NetCDF files and/or STDOUT
135    o fix re-definition bug in MNC_GRID_INIT_ALL()
136    o doc/api_reference added
137      - a framework for building an API Reference Manual using all
138        the "protex" comments embedded in the code
139      - see pkg/generic_advdiff, pkg/mnc for examples
140    o MNC:
141      - make myThid the last argument for all subroutines
142      - new default for the grid files: NO halos
143      - add useMNC and other run-time flags
144      - separate per-file-group handling of the unlimited dimension
145      - early initialization of MNC w/ flags read at the eeboot stage
146        and lookup tables set in initialize_fixed
147      - write all MNC output to a freshly-created directory
148    o thermodynamics sea-ice (thsice) is now tested with testreport.
149    o test exp. advect_cs: use the standard cs32 grid ; update output.
150    o Added functionality to grdchk:
151      pick global i,j,k position (or nearest wet) where to perform check.
152    
153    checkpoint52l_post
154    o new land formulation:
155      a) use ground enthalpy as prognostic variable to ensure exact
156         energy conservation.
157      b) account for water temperature and for latent heat of freezing
158         in all processes (rain, run-off, ground storage)
159      c) compute surface and ground temperature implicitly.
160    o aim_v23 modification for new land model:
161      a) Treat separately land / ocean / sea-ice surface fluxes
162         to allow implicit computation of land & sea-ice surface temp.
163      b) add snow precipitation.
164    checkpoint52l_pre
165    
166    o fix problem (when 1 tile is empty) in min/max monitor.
167    o fix bug in timeAve (u,vZetatave in common block)
168    o no restoring terms under ice for pkg/seaice
169    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
170    o bug fix for pkg/seaice pickups
171    o change MNC call locations and add coordinate attributes
172    o mask vorticity at the corner ; affects global_ocean.cs output
173    o fix ini_curvilinear_grid ; test CS experiments with mpi
174    o aim.5l_cs: modify sea-ice fraction input file ; update output
175    o exf: Adding simple range check routine for exf fields after read
176    
177    checkpoint52k_post
178    o removed top-level directory "diags"
179      - we migrated these functions to pkg/timeave a long time ago
180    o fixed bug introduced in pkg/monitor
181    o accuracy ctrlprec = 32 insuffient for gradient checks using
182      averaged fields (I/O via cost_averages)
183      -> use ctrl.h in active_file*.F to control I/O precision.
184    o paramter list of CALL ADTHE_MAIN_LOOP
185    o added initial do_the_model_io to ecco
186    o set all ...Freq to zero after cost_final
187      taveFreq, dumpFreq, pChkptFreq
188    o MAIN and ECCO differentiability restored
189    
190    checkpoint52j_post
191    o fix nchklev in tamc.h for global_ocean...
192    o Bringing flow and store directives up-to-date
193    o Really weird thing!
194      call do_the_model_io from the_main_loop with parameters
195      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
196      TAF places a faulty re-call of initialise_varia
197      after cost_final call which should not be there!
198    checkpoint52j_pre
199    
200    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
201      error messages
202    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
203    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
204      debug output
205    o modfied mdsio_writefield.F to handle non-global files under exch2
206    o update AIM Cubed-Sphere exp (aim.5l_cs):
207      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
208    o update AIM Equatorial Channel exp:
209      use standard aim_v23 pkg and change the SST fields to be more realistic.
210    o globalFile now works with exch2
211    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
212      mon_vort3.F to make exch2 friendly with >1 tile per cube face
213    o limit timeave output for hi-res integrations
214    
215    checkpoint52i_post
216    o removed CPP_EEOPTIONS.h from verification/*/code
217    o updated the tiling for global_ocean_pressure
218    checkpoint52i_pre
219    
220    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
221      the old pkg/aim).
222    
223    checkpoint52h_pre
224    o shortened offending lines in exch2_send_rx?.template
225    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
226    o genmake2: add build & execute test for NetCDF code
227    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
228      old grid files, moved CPP_EEMACROS.h to pkg/exch2
229    o added useSingleCPUIO flag to monitor.F and mon_out.F
230    o added temporary hack for sea-ice dynamics on the cube:
231      metric terms are ignored and it is assumed that
232      there is no sea-ice on cube faces 1, 2, 4, and 5.
233    
234    checkpoint52f_post
235    o added exch2 cube routines to pkg/exch2
236    o modified hs94.cs-32x32x5 to use it
237    o added new grid files to hs94.cs-32x32x5
238    checkpoint52f_pre
239    
240    checkpoint52e_post
241    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
242      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
243    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
244      to work with implicit vertical advection and AB ;
245    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
246    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
247     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
248    checkpoint52e_pre
249    
250    o fix bug in impldiff when Nr=1 or Nr=2.
251    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
252    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
253    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
254      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
255    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
256    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
257    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
258    
259    checkpoint52d_post
260    o re-tiled many expts to allow comparison in multi-processor mode
261      - updated output accordingly
262      - changed hs94.128x64x5 to use intial T from file rather than use the
263        random number generator
264    o add infrastructure in model routines for fizhi and gridalt packages
265    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
266    o changes to permit hi-res, cubed-sphere, configuration
267      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
268      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
269      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
270        of surface winds for the cube
271      (A verification experiment, based on global_ocean.cs32x15, but with
272       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
273       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
274       complete with example surface forcing files and matlab scripts to look
275       at the output and compare it with that of global_ocean.cs32x15.)
276    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
277       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
278       to conform to the common rule.
279    o check-in the first version of the coupler + interfaces for multi-components
280       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
281       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
282       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
283       - ocean and atmos. share the same horizontal grid (no interpolation).
284       - exchanges between component and coupler is done in forward_step
285    o new verification experiment, cpl_aim+ocn:
286       coupled ocean - AIM atmosphere on cs32 grid.
287    
288    checkpoint52d_pre
289    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
290    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
291    
292    checkpoint52c_post
293    o Fixing OPTIONS files for use of exf:
294      - ALLOW_ECCO not needed
295      - ECCO_CPPOPTIONS.h should not be included from
296        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
297        as has been the case in the past
298      - All cal/exf related options are currently set in
299        single header file. Should remain so until we
300        agree on a consistent new policy.
301    o Removed all CPP options for cal package.
302      cal has no more CPP options.
303    o modified STOREs in GAD_ADVECTION
304    o corrected key comp. for passkey
305    
306    checkpoint52b_post
307    o new version: "thsice" of thermodynamic sea-ice pkg:
308     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
309     - modify fluxes but do not change theta directly;
310     - light cleaning of bulk_force pkg (still needed with thsice).
311     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
312       + output_thsice.txt to test thsice & bulk_force pkgs.
313    o put back grid & coriolis monitor output.
314    checkpoint52b_pre
315    
316    o call "do_the_model_io" at the beginning (=> dump initial state)
317    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
318    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
319      (need info on NUMBER_OF_PTRACERS)
320    o missing PTRACERS headers in some routines
321    o default tamc.h in pkg/autodiff supposed to crash
322      to ensure proper customization
323    
324    checkpoint52a_post
325    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
326      - moved surfaceTendencyTice from pkg/seaice to main code
327      - subroutine FREEZE_SURFACE now limits only surface temperature
328        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
329        => new output.txt for global_ocean.cs32x15 & global_with_exf
330      - keep the old version of FREEZE for backward compatibility;
331        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
332      - corresponding modifs for TAF directives
333    o added surface flux output variables to TIMEAVE_STATVARS
334    o time-averaged output for pkg/ptracers
335    o fix problem with ECCO-related divided adjoint
336      snapshot file was missing some ad-variables,
337      but no warning issued by TAF
338    
339    checkpoint52a_pre
340    o some bug fixes for #undef REAL4_IS_SLOW
341    
342    checkpoint52 = ecco_c52_e35
343    o after testing adjoints of checkpoint51u_post
344    
345    checkpoint51u_post
346    o this is the post-merge tag of the ecco-branch
347      (needs another clean checkout and re-testing)
348    o various natl_box_adjoint configs and results
349      but no input fields
350    o obcs adjoint not yet merged!
351    o adding ECCO global 1x1 and 2x2 degree configs
352    o updated/extended some store directives for seaice
353    o pkg/ecco now containes ecco-specific part of cost function
354    o top level routines the_main_loop, forward_step
355      supersede those in model/src/
356      previous input data.cost now in data.ecco
357      (new namelist ecco_cost_nml)
358    o in ctrl/ cleaned some cross-dependencies and updated CPP options
359    
360    checkpoint51t_post
361    o this is the pre-merge tag of the ecco-branch
362    
363    checkpoint51s_post
364    o cleanup: removed various obsolete #define-s
365    o pkg/grdchk
366      - renamed 'ph-grd 3' to 'grad-res'
367      - merged from ecco-branch
368        (remaining bug fixes for obcs gradient checks)
369      - additional high-precision output for testreport
370        (grep for 'precision_grdchk_result')
371    
372    checkpoint51r_post
373    o cleaned up or removed CPP_OPTIONS.h files
374    o updated results for some of the tests to reflect the new
375      optfiles (-ieee: -O0 instead of -O3)
376    
377    checkpoint51q_post
378    o cd_code:
379      - moved cd_scheme.F -> cd_code_scheme.F
380      - separate read_checkpoint from cd_code_ini_vars.F
381      - separated cd_code part from write_checkpoint
382      - updated AD_SOURCE, generated .flow
383      - added CD_CODE_VARS.h to the_main_loop
384      - Moving cd_code specific store dir.s to pkg/cd_code
385    o ctrl package totally restructured
386      - pack/unpack now optional and decoupled from
387        xx_/adxx_ I/O
388      - ctrl_pack/unpack cleaned
389        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
390      - confined inclusion of AD_CONFIG.h to where necessary.
391    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
392    
393    checkpoint51p_post
394    o create initial cd_code package
395      - WARNING: the initialization of fields within packages
396        is broken because INI_FIELDS (where READ_CHECKPOINT is
397        called) is called *before* PACKAGES_INIT_VARIABLES.
398        This seems to be backwards since
399        1) its important to initially zero the entire field including
400           the "halo" region
401        2) zeroing needs to be done *before* reading pickup info
402           and the pickup call might or might not happen in any

533    o Added on-the-fly spatial interpolation capability
534        "USE_EXF_INTERPOLATION" to pkg/exf.
535      - This is a temporary Cartesian-grid hack until
536        the super-duper ESMF coupler becomes available.
537      - See verification/global_with_exf/README for usage example.
538      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

568    o introducing integer flag debugLevel
569      - debLevZero: suppress all output
570      - debLevA: standard
571      - debLevB: equivalent to current debugMode=.TRUE.
572    o introducing pathname variable mdsioLocalDir for mdsio
573      that can be specified at runtime
574      (relevant for cluster I/O to local disk)
575    `
576    >>>checkpoint51b_post
577    adjoint of ptracers

592      - new pkgs: dic, gchem
593      - new subroutine in ptracers
594    o modify code for biogeo packages
595      - in model/src and pkg/ptracers
596    
597    checkpoint51
598    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
599      - autodiff, ctrl, exf, grdchk, seaice
600      kept separate packages
601      - cost, ecco, obcs
602    o updating verification/internal_wave, verification/lab_sea
603      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
604    
605    checkpoint50i_post
606    o Preparing next differentiable checkpoint and sync
607      of MAIN vs. ecco-branch
608      - 1st step: this one is differentiable
609      - 2nd step: next(! not this) checkpoint will have updated packages
610                  from ecco-branch)
611    
612    checkpoint50h_post
613    o new package "land": provide surface BC for AIM.
614    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
615    o AIM: use true log-P extrapolation for near surface temp (= as in
616        F.Molteni paper) ; update aim.5l_cs output.
617    o New variable in PARM03 for more flexible pickups
618    o somewhat cleaned package initialisation sequence for
619      ctrl/ cost/ ecco/ in packages_... routines
620    
621    checkpoint50g_post
622    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
623      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
624      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
625        made the default because of faster convergence than ADI
626    
627    checkpoint50f_post
628    o exf totally restructured
629      - replaced all exf_set_ routines by one generic exf_set_gen.F
630        and made sure it's still differentiable
631      - split exf_getffields.F into new exf_bulkformulae.F

643     o removed lots of single quotes from comments
644    
645    checkpoint50e_post
646    o make KPP work with PTRACERS
647     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
648       nearly a copy of kpp_transport_s
649     - there is no analogue to SurfaceTendencyS, so I have to use
650       gPtr(of the surface layer) instead
651    o add a new platform SunFire+mpi (SunFire 15000) to genmake
652    checkpoint50e_pre
653    
654    checkpoint50d_post
655    o change kpp output from multiple-record state files to single-record state
656      files analogous to write_state.F
657    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
658      analogous to the cg2d-related output.
659    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
660      so that writing to internal file fn (with length 512) fails.
661    checkpoint50d_pre
662    
663    checkpoint50c_post
664    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)

666    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
667    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
668    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
669    
670    checkpoint50c_pre
671    Merging from release1_p13:

673    o Added SEAICE_initialHEFF to pkg/seaice
674    
675    checkpoint50b_post
676    o store u*,v* in gU,V instead of in guNm1,gvNm1
677    o in order to put the momForcing out of the Adams-Bashforth:
678      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
679      to timestep.F
680    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
681    o re-generate output for highly sensitive test-exp:
682       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
683    
684    checkpoint50b_pre
685    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
686    o corrected CPP option mismatch in exf_Bulk... functions for case
687      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
688    
689    checkpoint50a_post
690    o Bug fix for merging between c50 and KPP.
691      ikey was passed from thermodynamics to kpp_calc via
692      common block rather than being recomputed in kpp_calc,
693      in contradiction with new key itdkey.
694      New key ikppkey created, and tamc.h headers updated.
695    
696    checkpoint50
697    - 2nd step of merge with ecco-branch:
698      merge changes in ecco-branch back into main trunk
699    - bug fix in find_alpha
700    - more storing in gmredi_calc_tensor.F, kpp_routines.F
701    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
702    - merged some sliced AD support routines
703    
704    checkpoint49
705    merged from ecco-branch:
706    o exf:
707      - Enable initialisation of forcing fields to constant
708        (runtime) values.
709      - in exf_getffields.F
710        Reduce i-/j-loop to interior domain, discarding overlaps.
711        That also fixes wrong TAF-key computations for key_1, key_2
712        with bulf formulae.
713      - exf_init.F modify #ifdef for exf_init_evap
714      - exf_getffieldrec.F, ctrl_getrec.F
715        The following INT-usages are not safe:
716          fldsecs  = int(fldsecs/fldperiod)*fldperiod
717          fldcount = int(fldsecs/fldperiod) + 1
718        and were modified.
719    o autodiff: checkpoint_lev...
720      - updated storing for bulk formulae (some arrays were missing)
721      - added state for seaice package
722      - synchronized with main branch
723    o DIVA:
724      Modif.s in
725      - the_main_loop.F
726      - the_model_main.F
727      and added cost_final_restore.F cost_final_store.F
728      o With these changes, it is possible to fully separate
729        the first forward run to compute the cost function (mdthe_main_loop)
730        and adjoint runs over individual DIVA intervals (adthe_main_loop)
731        into separate model executions.
732        This enables better tuning of DIVA to given queue sizes.
733      o Loss of cost function value in consecutive DIVA runs is
734        fixed by storing to 'costfinal' file.
735      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
736        beginning/end of adjoint integration is accounted for.
737      The current changes apply to TAF-1.4.26.
738      TAF has one remaining bug, requiring one manual change
739      (see MITgcm manual).
740    o cal: synchronized between MAIN and ecco-branch
741    
742    checkpoint48i_post
743    o Changes to restore differentiability of code w.r.t. previous tag
744      (mostly adding new routines to make list and replacing
745      pressure by totPhiHyd).
746    o Updated and merged grdchk package
747      - has both ADM and TLM checks
748      - works for single- and multi-proc.
749      - output cleaned
750      - worked successfully for parallel DIVA
751    o genmake:
752      - Adding -platform=SP4
753      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
754    o Modif. for DIVA:
755      ctrl_unpack should not be called in intermediate DIVA interval.
756      (similar thing would apply for active files such as
757      tbar, sbar, psbar, which should not be reinitialised;
758      only relevant for ecco-branch)
759    
760    checkpoint48h_post
761    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
762    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
763    o Added SEAICE_initialHEFF to pkg/seaice
764    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
765    
766    checkpoint48g_post
767    --- EOS:
768    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
769      store total Potential in totPhyHyd for diagnostics & EOS.
770    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
771    --- Pressure/geopotential gradient:
772    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
773    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
774      ( changes results of global_ocean_pressure )
775    o NLFS + z-coord.: add eta*Rho' contribution.
776    o accurate phiHyd when using interface-W at the middle between 2 centers
777     ( changes results of ideal_2D_oce )
778    o includes r* 2nd term in potential gradient.
779    
780    checkpoint48f_post
781    Merging from release1_p12:

788      (SBO) core products, including oceanic mass, center-of-mass,
789      angular, and bottom pressure (see pkg/sbo/README.sbo).
790    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
791      to avoid negative values in shallow regions.
792      - updated verification/natl_box/results/output.txt
793      - updated verification/lab_sea/results/output.txt
794    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
795    o Added useSingleCpuIO option (see PARAMS.h).
796    o Updated useSingleCpuIO option in mdsio_writefield.F to
797      work with multi-field files, e.g., for single-file pickup.
798    o pkg/seaice:
799      - bug fix in growth.F: QNET for no shortwave case
800      - added HeffFile for specifying initial sea-ice thickness
801      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
802    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,

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

1426                        bi,bj loop
1427      mdsio_writelocal - same as mdsio_writetile except works for local
1428                         arrays
1429      write_local_r? - higher-level wrapper for mdsio_writelocal
1430      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1431      Example given at end of mom_vecinv.F that dumps some local arrays.

1435      or genmake -DISABLE ...
1436    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1437      (additional storing is now needed for case vecinv;
1438      currently nothing implemented to switch this storing off

1455    
1456    checkpoint40pre5
1457    o proper initialization of Adams-Bashforth time stepping
1458      + uses forward step for very first step of model (iter=0)
1459    o re-generated *all* output since almost all output is modified by this
1460      change (sorry but we've been putting this one off for about 2 years)
1461      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1462        *not* regenerated since they are already out of date and I don't
1463        want to create the impression that they are suddenly working.
1464    o removed KAP stuff for DEC's
1465    o modified/added many .cvsignore files in */code and */input
1466    o added new expt "solid-body.cs-32x32x1"
1467      + this uses an alternative form of ini_curvilinear_grid.F which
1468        is not necessarily any better than the current one...
1469
