6    
7    checkpoint53e_pre
8    
9    checkpoint53d_post
10    o faulks upgraded: re-generate output.txt that have changed:
11       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
12    o Added Bryan and Lewis, 1979, vertical diffusivity profile
13    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
14    o added Sadourny discretization of Coriolis
15      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
16      - re-enabled use of omega3 (useAbsVorticity)
17    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
18      vector-invariant equations
19      - note: does *NOT* yet use same variable visc. for no-slip BC's.
20    o recoded the lateral boundary conditions for non-hydrostatic w, this time
21      hopefully without new bugs
22      - still to do: biharmonic friction for non-hydrostatic w
23    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
24    o regenerated output for global_ocean_ebm (using -ieee)
25    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
26      of mom_common/
27      - simple re-arrangement of instructions within computing loop
28    checkpoint53d_pre
29    
30    checkpoint53c_post
31    o new version of coupler for AIM+thSIce and Ocean models
32     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
33     - land: change Evaporation of snow
34     - aim with thSIce: fix bug in snow-precip.
35    o changes to calc_gw.F
36     - bug fix for w^2 term near the bottom boundary
37     - (hopefully) improve the lateral slip boundary condtions for use with
38        partial/looped cells
39      - because the bug fix changes two verification experiments anyway (exp5
40        and plume on slope), change the lateral boundary condition from half slip
41        to the value of no_slip_sides
42    o ebm package wasnt quite up to the parallel task. Fixed that.
43    o Adjoint of EBM package + verification
44      * TLM OK
45      * ADM not sufficient accuracy yet (needs further testing)
46    
47    checkpoint53b_post
48    o Commiting new energy balance model to repository
49      * package is pkg/ebm
50      * verif. is verification/global_ocean_ebm
51      * references are in ebm_driver.F
52    C      * X. Wang, P. Stone and J. Marotzke, 1999:
53    C        Global thermohaline circulation. Part I:
54    C        Sensitivity to atmospheric moisture transport.
55    C        J. Climate 12(1), 71-82
56    C      * X. Wang, P. Stone and J. Marotzke, 1999:
57    C        Global thermohaline circulation. Part II:
58    C        Sensitivity with interactive transport.
59    C        J. Climate 12(1), 83-91
60    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
61    C        Destabilization of the thermohaline circulation
62    C        by atmospheric eddy transports.
63    C        J. Climate 7(12), 1870-1882
64    o Will need long integration testing.
65    checkpoint53b_pre
66    
67    o created pkg/mom_common in preparation for variable viscosity code
68    o renamed and split ini_mnc_io
69    o pkg/land: only liquid water can diffuse or run-off
70    o AIM using land: soil wetness availability account for snow
71    o added printMapIncludesZeros to EEPARMS namelist
72    
73    checkpoint53a_post
74    o restore TAMC compatiility for exf_constants.h
75      (no usage of _d in .h)
76    o Additional storing in KPP in an attempt to fix
77      TAMC problem with adjoint of KPP code.
78      (no success...)
79      Identical code works fine with TAF.
80    o Fixed verification/natl_box_adjoint experiments.
81      Initial conditions for Experiments 4 and 5 are now
82      set to "SEAICE_initialHEFF=0", which is more reasonable,
83      and hence gives results closer to that of Experiment 2.
84      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
85    
86    checkpoint53
87    o stable checkpoint with up to date adjoint
88      TLM tests only run for 1st grdchk at the moment. Its unclear if
89      this is a code problem or a problem with resetting code for g_
90      variables that is being autogenerated wrong.
91      Otherwise:
92       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
93       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
94         are both still in chaos following their security messes.
95    
96    checkpoint52n_post
97    o various build (mostly genmake2) changes including:
98      - ability to build/run more easily within Cygwin and MacOS X
99      - more complicated Makefiles with a stronger dependence on Gnu Make
100    o pkg/seaice modifications
101      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
102        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
103        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
104      - changed proxy for geostrophic velocity and updated
105        verification/lab_sea/results/* accordingly
106      - removed ADI dynamic solver from pkg/seaice
107      - replaced all occurrences of 1/CSTICE or 1/CSUICE
108        they caused a segmentation fault under certain circumstances
109      - removed unused field WATR
110    o bug fix in exf-package:
111      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
112         now reflect that.
113    o small fixes in the cal-package:
114      - set reference date to first of January for the 'model'-calendar
115      - failing of cal_CheckDate in cal_FullDate now actually results in a
116        warning
117    o small modifications in exf-package to increase flexibility:
118      - change climtempfreeze from a constant to a runtime parameter that
119        is specified in data.exf_clim (default = -1.9)
120      - introduce runtime parameter windstressmax (default = 2.0) that is
121        specified in data.exf
122    o fix in pkg/thsice:
123      - update Evap (Tsf changes) to be consistent with Latent heat flux
124      - maintain snow precipitation unchanged (even if Tsf >=0).
125     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
126    
127    checkpoint52m_post
128    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
129      this does not change any of the results, because myIter=0 in swfrac always
130      lead to jwtype=2 (the default anyway), but the call makes little sense
131      as a default
132    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
133    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
134      atmospheric model (AIM) to use it ; add a "slab ocean" component.
135    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
136    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
137    o extending useSingleCpuIO option to work with new exch2 I/O format
138      - old-style, missing-tile I/O is still accessible by defining CPP
139        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
140    o monitor package can write to NetCDF files and/or STDOUT
141    o fix re-definition bug in MNC_GRID_INIT_ALL()
142    o doc/api_reference added
143      - a framework for building an API Reference Manual using all
144        the "protex" comments embedded in the code
145      - see pkg/generic_advdiff, pkg/mnc for examples
146    o MNC:
147      - make myThid the last argument for all subroutines
148      - new default for the grid files: NO halos
149      - add useMNC and other run-time flags
150      - separate per-file-group handling of the unlimited dimension
151      - early initialization of MNC w/ flags read at the eeboot stage
152        and lookup tables set in initialize_fixed
153      - write all MNC output to a freshly-created directory
154    o thermodynamics sea-ice (thsice) is now tested with testreport.
155    o test exp. advect_cs: use the standard cs32 grid ; update output.
156    o Added functionality to grdchk:
157      pick global i,j,k position (or nearest wet) where to perform check.
158    
159    checkpoint52l_post
160    o new land formulation:
161      a) use ground enthalpy as prognostic variable to ensure exact
162         energy conservation.
163      b) account for water temperature and for latent heat of freezing
164         in all processes (rain, run-off, ground storage)
165      c) compute surface and ground temperature implicitly.
166    o aim_v23 modification for new land model:
167      a) Treat separately land / ocean / sea-ice surface fluxes
168         to allow implicit computation of land & sea-ice surface temp.
169      b) add snow precipitation.
170    checkpoint52l_pre
171    
172    o fix problem (when 1 tile is empty) in min/max monitor.
173    o fix bug in timeAve (u,vZetatave in common block)
174    o no restoring terms under ice for pkg/seaice
175    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
176    o bug fix for pkg/seaice pickups
177    o change MNC call locations and add coordinate attributes
178    o mask vorticity at the corner ; affects global_ocean.cs output
179    o fix ini_curvilinear_grid ; test CS experiments with mpi
180    o aim.5l_cs: modify sea-ice fraction input file ; update output
181    o exf: Adding simple range check routine for exf fields after read
182    
183    checkpoint52k_post
184    o removed top-level directory "diags"
185      - we migrated these functions to pkg/timeave a long time ago
186    o fixed bug introduced in pkg/monitor
187    o accuracy ctrlprec = 32 insuffient for gradient checks using
188      averaged fields (I/O via cost_averages)
189      -> use ctrl.h in active_file*.F to control I/O precision.
190    o paramter list of CALL ADTHE_MAIN_LOOP
191    o added initial do_the_model_io to ecco
192    o set all ...Freq to zero after cost_final
193      taveFreq, dumpFreq, pChkptFreq
194    o MAIN and ECCO differentiability restored
195    
196    checkpoint52j_post
197    o fix nchklev in tamc.h for global_ocean...
198    o Bringing flow and store directives up-to-date
199    o Really weird thing!
200      call do_the_model_io from the_main_loop with parameters
201      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
202      TAF places a faulty re-call of initialise_varia
203      after cost_final call which should not be there!
204    checkpoint52j_pre
205    
206    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
207      error messages
208    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
209    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
210      debug output
211    o modfied mdsio_writefield.F to handle non-global files under exch2
212    o update AIM Cubed-Sphere exp (aim.5l_cs):
213      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
214    o update AIM Equatorial Channel exp:
215      use standard aim_v23 pkg and change the SST fields to be more realistic.
216    o globalFile now works with exch2
217    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
218      mon_vort3.F to make exch2 friendly with >1 tile per cube face
219    o limit timeave output for hi-res integrations
220    
221    checkpoint52i_post
222    o removed CPP_EEOPTIONS.h from verification/*/code
223    o updated the tiling for global_ocean_pressure
224    checkpoint52i_pre
225    
226    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
227      the old pkg/aim).
228    
229    checkpoint52h_pre
230    o shortened offending lines in exch2_send_rx?.template
231    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
232    o genmake2: add build & execute test for NetCDF code
233    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
234      old grid files, moved CPP_EEMACROS.h to pkg/exch2
235    o added useSingleCPUIO flag to monitor.F and mon_out.F
236    o added temporary hack for sea-ice dynamics on the cube:
237      metric terms are ignored and it is assumed that
238      there is no sea-ice on cube faces 1, 2, 4, and 5.
239    
240    checkpoint52f_post
241    o added exch2 cube routines to pkg/exch2
242    o modified hs94.cs-32x32x5 to use it
243    o added new grid files to hs94.cs-32x32x5
244    checkpoint52f_pre
245    
246    checkpoint52e_post
247    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
248      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
249    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
250      to work with implicit vertical advection and AB ;
251    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
252    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
253     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
254    checkpoint52e_pre
255    
256    o fix bug in impldiff when Nr=1 or Nr=2.
257    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
258    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
259    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
260      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
261    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
262    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
263    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
264    
265    checkpoint52d_post
266    o re-tiled many expts to allow comparison in multi-processor mode
267      - updated output accordingly
268      - changed hs94.128x64x5 to use intial T from file rather than use the
269        random number generator
270    o add infrastructure in model routines for fizhi and gridalt packages
271    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
272    o changes to permit hi-res, cubed-sphere, configuration
273      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
274      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
275      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
276        of surface winds for the cube
277      (A verification experiment, based on global_ocean.cs32x15, but with
278       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
279       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
280       complete with example surface forcing files and matlab scripts to look
281       at the output and compare it with that of global_ocean.cs32x15.)
282    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
283       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
284       to conform to the common rule.
285    o check-in the first version of the coupler + interfaces for multi-components
286       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
287       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
288       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
289       - ocean and atmos. share the same horizontal grid (no interpolation).
290       - exchanges between component and coupler is done in forward_step
291    o new verification experiment, cpl_aim+ocn:
292       coupled ocean - AIM atmosphere on cs32 grid.
293    
294    checkpoint52d_pre
295    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
296    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
297    
298    checkpoint52c_post
299    o Fixing OPTIONS files for use of exf:
300      - ALLOW_ECCO not needed
301      - ECCO_CPPOPTIONS.h should not be included from
302        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
303        as has been the case in the past
304      - All cal/exf related options are currently set in
305        single header file. Should remain so until we
306        agree on a consistent new policy.
307    o Removed all CPP options for cal package.
308      cal has no more CPP options.
309    o modified STOREs in GAD_ADVECTION
310    o corrected key comp. for passkey
311    
312    checkpoint52b_post
313    o new version: "thsice" of thermodynamic sea-ice pkg:
314     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
315     - modify fluxes but do not change theta directly;
316     - light cleaning of bulk_force pkg (still needed with thsice).
317     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
318       + output_thsice.txt to test thsice & bulk_force pkgs.
319    o put back grid & coriolis monitor output.
320    checkpoint52b_pre
321    
322    o call "do_the_model_io" at the beginning (=> dump initial state)
323    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
324    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
325      (need info on NUMBER_OF_PTRACERS)
326    o missing PTRACERS headers in some routines
327    o default tamc.h in pkg/autodiff supposed to crash
328      to ensure proper customization
329    
330    checkpoint52a_post
331    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
332      - moved surfaceTendencyTice from pkg/seaice to main code
333      - subroutine FREEZE_SURFACE now limits only surface temperature
334        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
335        => new output.txt for global_ocean.cs32x15 & global_with_exf
336      - keep the old version of FREEZE for backward compatibility;
337        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
338      - corresponding modifs for TAF directives
339    o added surface flux output variables to TIMEAVE_STATVARS
340    o time-averaged output for pkg/ptracers
341    o fix problem with ECCO-related divided adjoint
342      snapshot file was missing some ad-variables,
343      but no warning issued by TAF
344    
345    checkpoint52a_pre
346    o some bug fixes for #undef REAL4_IS_SLOW
347    
348    checkpoint52 = ecco_c52_e35
349    o after testing adjoints of checkpoint51u_post
350    
351    checkpoint51u_post
352    o this is the post-merge tag of the ecco-branch
353      (needs another clean checkout and re-testing)
354    o various natl_box_adjoint configs and results
355      but no input fields
356    o obcs adjoint not yet merged!
357    o adding ECCO global 1x1 and 2x2 degree configs
358    o updated/extended some store directives for seaice
359    o pkg/ecco now containes ecco-specific part of cost function
360    o top level routines the_main_loop, forward_step
361      supersede those in model/src/
362      previous input data.cost now in data.ecco
363      (new namelist ecco_cost_nml)
364    o in ctrl/ cleaned some cross-dependencies and updated CPP options
365    
366    checkpoint51t_post
367    o this is the pre-merge tag of the ecco-branch
368    
369    checkpoint51s_post
370    o cleanup: removed various obsolete #define-s
371    o pkg/grdchk
372      - renamed 'ph-grd 3' to 'grad-res'
373      - merged from ecco-branch
374        (remaining bug fixes for obcs gradient checks)
375      - additional high-precision output for testreport
376        (grep for 'precision_grdchk_result')
377    
378    checkpoint51r_post
379    o cleaned up or removed CPP_OPTIONS.h files
380    o updated results for some of the tests to reflect the new
381      optfiles (-ieee: -O0 instead of -O3)
382    
383    checkpoint51q_post
384    o cd_code:
385      - moved cd_scheme.F -> cd_code_scheme.F
386      - separate read_checkpoint from cd_code_ini_vars.F
387      - separated cd_code part from write_checkpoint
388      - updated AD_SOURCE, generated .flow
389      - added CD_CODE_VARS.h to the_main_loop
390      - Moving cd_code specific store dir.s to pkg/cd_code
391    o ctrl package totally restructured
392      - pack/unpack now optional and decoupled from
393        xx_/adxx_ I/O
394      - ctrl_pack/unpack cleaned
395        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
396      - confined inclusion of AD_CONFIG.h to where necessary.
397    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
398    
399    checkpoint51p_post
400    o create initial cd_code package
401      - WARNING: the initialization of fields within packages
402        is broken because INI_FIELDS (where READ_CHECKPOINT is
403        called) is called *before* PACKAGES_INIT_VARIABLES.
404        This seems to be backwards since
405        1) its important to initially zero the entire field including
406           the "halo" region
407        2) zeroing needs to be done *before* reading pickup info
408           and the pickup call might or might not happen in any
409           particular run
410      - this needs an overhaul for R2
411    o cleanup verification/*/code/GMREDI_OPTIONS.h
412    o cleanup testreport
413    
414    checkpoint51o_post
415    o bringing AD-related verif's up to date with genmake2

421    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
422    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
423    o bug fix in find_alpha.F for MDJWF:
424      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
425        change rho -> rho-rhoConst
426      - replace call find_rho to find_rhonum
427    o initialisation of rFlx extended to full array (required by TAF)
428      and shifted to thermodynamics
429    o removed PTRACERS.h in ptracers routine
430    o added surfacetendencyPtr to S/R parameter list pracers_forcing

536      of tracer Green's fucntions for ocean inversion project.
537    
538    checkpoint51f_pre
539    o Added on-the-fly spatial interpolation capability
540        "USE_EXF_INTERPOLATION" to pkg/exf.
541      - This is a temporary Cartesian-grid hack until
542        the super-duper ESMF coupler becomes available.
543      - See verification/global_with_exf/README for usage example.
544      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
545        flags and modified pkg/seaice accordingly.
546    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,

573    checkpoint51c_post
574    o introducing integer flag debugLevel
575      - debLevZero: suppress all output
576      - debLevA: standard
577      - debLevB: equivalent to current debugMode=.TRUE.
578    o introducing pathname variable mdsioLocalDir for mdsio
579      that can be specified at runtime
580      (relevant for cluster I/O to local disk)
581    `
582    >>>checkpoint51b_post
583    adjoint of ptracers
584    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM

594    <<<checkpoint51b_pre
595    
596    checkpoint51a_post
597    o added code for biogeochemistry package
598      - new pkgs: dic, gchem
599      - new subroutine in ptracers
600    o modify code for biogeo packages
601      - in model/src and pkg/ptracers
602    
603    checkpoint51
604    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
605      - autodiff, ctrl, exf, grdchk, seaice
606      kept separate packages
607      - cost, ecco, obcs
608    o updating verification/internal_wave, verification/lab_sea
609      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
610    
611    checkpoint50i_post
612    o Preparing next differentiable checkpoint and sync
613      of MAIN vs. ecco-branch
614      - 1st step: this one is differentiable
615      - 2nd step: next(! not this) checkpoint will have updated packages
616                  from ecco-branch)
617    
618    checkpoint50h_post
619    o new package "land": provide surface BC for AIM.
620    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
621    o AIM: use true log-P extrapolation for near surface temp (= as in
622        F.Molteni paper) ; update aim.5l_cs output.
623    o New variable in PARM03 for more flexible pickups
624    o somewhat cleaned package initialisation sequence for
625      ctrl/ cost/ ecco/ in packages_... routines
626    
627    checkpoint50g_post
628    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
629      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
630      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
631        made the default because of faster convergence than ADI
632    
633    checkpoint50f_post
634    o exf totally restructured
635      - replaced all exf_set_ routines by one generic exf_set_gen.F
636        and made sure it's still differentiable
637      - split exf_getffields.F into new exf_bulkformulae.F
638      - exf_inscal_/exf_outscal_ suffixes consistent with field names

649     o removed lots of single quotes from comments
650    
651    checkpoint50e_post
652    o make KPP work with PTRACERS
653     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
654       nearly a copy of kpp_transport_s
655     - there is no analogue to SurfaceTendencyS, so I have to use
656       gPtr(of the surface layer) instead
657    o add a new platform SunFire+mpi (SunFire 15000) to genmake
658    checkpoint50e_pre
659    
660    checkpoint50d_post
661    o change kpp output from multiple-record state files to single-record state
662      files analogous to write_state.F
663    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
664      analogous to the cg2d-related output.
665    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
666      so that writing to internal file fn (with length 512) fails.
667    checkpoint50d_pre
668    
669    checkpoint50c_post
670    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
671    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
672    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
673    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
674    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
675    
676    checkpoint50c_pre
677    Merging from release1_p13:
678    o bug fix for pkg/seaice dynamic solver
679    o Added SEAICE_initialHEFF to pkg/seaice
680    
681    checkpoint50b_post
682    o store u*,v* in gU,V instead of in guNm1,gvNm1
683    o in order to put the momForcing out of the Adams-Bashforth:
684      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
685      to timestep.F
686    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
687    o re-generate output for highly sensitive test-exp:
688       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
689    
690    checkpoint50b_pre
691    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
692    o corrected CPP option mismatch in exf_Bulk... functions for case
693      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
694    
695    checkpoint50a_post
696    o Bug fix for merging between c50 and KPP.
697      ikey was passed from thermodynamics to kpp_calc via
698      common block rather than being recomputed in kpp_calc,
699      in contradiction with new key itdkey.
700      New key ikppkey created, and tamc.h headers updated.
701    
702    checkpoint50
703    - 2nd step of merge with ecco-branch:
704      merge changes in ecco-branch back into main trunk
705    - bug fix in find_alpha
706    - more storing in gmredi_calc_tensor.F, kpp_routines.F
707    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
708    - merged some sliced AD support routines
709    
710    checkpoint49
711    merged from ecco-branch:
712    o exf:
713      - Enable initialisation of forcing fields to constant
714        (runtime) values.
715      - in exf_getffields.F
716        Reduce i-/j-loop to interior domain, discarding overlaps.
717        That also fixes wrong TAF-key computations for key_1, key_2
718        with bulf formulae.
719      - exf_init.F modify #ifdef for exf_init_evap
720      - exf_getffieldrec.F, ctrl_getrec.F
721        The following INT-usages are not safe:
722          fldsecs  = int(fldsecs/fldperiod)*fldperiod
723          fldcount = int(fldsecs/fldperiod) + 1
724        and were modified.
725    o autodiff: checkpoint_lev...
726      - updated storing for bulk formulae (some arrays were missing)
727      - added state for seaice package
728      - synchronized with main branch
729    o DIVA:
730      Modif.s in
731      - the_main_loop.F
732      - the_model_main.F
733      and added cost_final_restore.F cost_final_store.F
734      o With these changes, it is possible to fully separate
735        the first forward run to compute the cost function (mdthe_main_loop)
736        and adjoint runs over individual DIVA intervals (adthe_main_loop)
737        into separate model executions.
738        This enables better tuning of DIVA to given queue sizes.
739      o Loss of cost function value in consecutive DIVA runs is
740        fixed by storing to 'costfinal' file.
741      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
742        beginning/end of adjoint integration is accounted for.
743      The current changes apply to TAF-1.4.26.
744      TAF has one remaining bug, requiring one manual change
745      (see MITgcm manual).
746    o cal: synchronized between MAIN and ecco-branch
747    
748    checkpoint48i_post
749    o Changes to restore differentiability of code w.r.t. previous tag
750      (mostly adding new routines to make list and replacing
751      pressure by totPhiHyd).
752    o Updated and merged grdchk package
753      - has both ADM and TLM checks
754      - works for single- and multi-proc.
755      - output cleaned
756      - worked successfully for parallel DIVA
757    o genmake:
758      - Adding -platform=SP4
759      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
760    o Modif. for DIVA:
761      ctrl_unpack should not be called in intermediate DIVA interval.
762      (similar thing would apply for active files such as
763      tbar, sbar, psbar, which should not be reinitialised;
764      only relevant for ecco-branch)
765    
766    checkpoint48h_post
767    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
768    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
769    o Added SEAICE_initialHEFF to pkg/seaice
770    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
771    
772    checkpoint48g_post
773    --- EOS:
774    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
775      store total Potential in totPhyHyd for diagnostics & EOS.
776    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
777    --- Pressure/geopotential gradient:
778    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
779    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
780      ( changes results of global_ocean_pressure )
781    o NLFS + z-coord.: add eta*Rho' contribution.
782    o accurate phiHyd when using interface-W at the middle between 2 centers
783     ( changes results of ideal_2D_oce )
784    o includes r* 2nd term in potential gradient.
785    
786    checkpoint48f_post
787    Merging from release1_p12:

794      (SBO) core products, including oceanic mass, center-of-mass,
795      angular, and bottom pressure (see pkg/sbo/README.sbo).
796    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
797      to avoid negative values in shallow regions.
798      - updated verification/natl_box/results/output.txt
799      - updated verification/lab_sea/results/output.txt
800    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
801    o Added useSingleCpuIO option (see PARAMS.h).
802    o Updated useSingleCpuIO option in mdsio_writefield.F to
803      work with multi-field files, e.g., for single-file pickup.
804    o pkg/seaice:
805      - bug fix in growth.F: QNET for no shortwave case
806      - added HeffFile for specifying initial sea-ice thickness
807      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
808    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
809      kpp_transport_t.F, forward_step.F, and the_main_loop.F
810    o pkg/seaice:
811      - adjoint-friendly modifications
812      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
813    
814    checkpoint48e_post
815    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
816    o dynamics: change definition of computational domain & adapt mom_fluxform
817      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
818    o following exp works with Olx=Oly=2 (and pass through checkbounds option):

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

1329      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1330        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1331        line in data.pkg.
1332      + This package is disabled by default since it increases storage.
1333    
1334    
1335    o testscript: added -cleanup option

1429    o new package rw/
1430      Added method for dumping intermediate local arrays:
1431      mdsio_writetile - same as mdsio_writefield except works from inside
1432                        bi,bj loop
1433      mdsio_writelocal - same as mdsio_writetile except works for local
1434                         arrays
1435      write_local_r? - higher-level wrapper for mdsio_writelocal
1436      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1437      Example given at end of mom_vecinv.F that dumps some local arrays.

1441      or genmake -DISABLE ...
1442    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1443      (additional storing is now needed for case vecinv;
1444      currently nothing implemented to switch this storing off

1461    
1462    checkpoint40pre5
1463    o proper initialization of Adams-Bashforth time stepping
1464      + uses forward step for very first step of model (iter=0)
1465    o re-generated *all* output since almost all output is modified by this
1466      change (sorry but we've been putting this one off for about 2 years)
1467      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1468        *not* regenerated since they are already out of date and I don't
1469        want to create the impression that they are suddenly working.
1470    o removed KAP stuff for DEC's
1471    o modified/added many .cvsignore files in */code and */input
1472    o added new expt "solid-body.cs-32x32x1"
1473      + this uses an alternative form of ini_curvilinear_grid.F which
