3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint53b_pre
7    
8    o created pkg/mom_common in preparation for variable viscosity code
9    o renamed and split ini_mnc_io
10    o pkg/land: only liquid water can diffuse or run-off
11    o AIM using land: soil wetness availability account for snow
12    o added printMapIncludesZeros to EEPARMS namelist
13    
14    checkpoint53a_post
15    o restore TAMC compatiility for exf_constants.h
16      (no usage of _d in .h)
17    o Additional storing in KPP in an attempt to fix
18      TAMC problem with adjoint of KPP code.
19      (no success...)
20      Identical code works fine with TAF.
21    o Fixed verification/natl_box_adjoint experiments.
22      Initial conditions for Experiments 4 and 5 are now
23      set to "SEAICE_initialHEFF=0", which is more reasonable,
24      and hence gives results closer to that of Experiment 2.
25      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
26    
27    checkpoint53
28    o stable checkpoint with up to date adjoint
29      TLM tests only run for 1st grdchk at the moment. Its unclear if
30      this is a code problem or a problem with resetting code for g_
31      variables that is being autogenerated wrong.
32      Otherwise:
33       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
34       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
35         are both still in chaos following their security messes.
36    
37    checkpoint52n_post
38    o various build (mostly genmake2) changes including:
39      - ability to build/run more easily within Cygwin and MacOS X
40      - more complicated Makefiles with a stronger dependence on Gnu Make
41    o pkg/seaice modifications
42      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
43        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
44        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
45      - changed proxy for geostrophic velocity and updated
46        verification/lab_sea/results/* accordingly
47      - removed ADI dynamic solver from pkg/seaice
48      - replaced all occurrences of 1/CSTICE or 1/CSUICE
49        they caused a segmentation fault under certain circumstances
50      - removed unused field WATR
51    o bug fix in exf-package:
52      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
53         now reflect that.
54    o small fixes in the cal-package:
55      - set reference date to first of January for the 'model'-calendar
56      - failing of cal_CheckDate in cal_FullDate now actually results in a
57        warning
58    o small modifications in exf-package to increase flexibility:
59      - change climtempfreeze from a constant to a runtime parameter that
60        is specified in data.exf_clim (default = -1.9)
61      - introduce runtime parameter windstressmax (default = 2.0) that is
62        specified in data.exf
63    o fix in pkg/thsice:
64      - update Evap (Tsf changes) to be consistent with Latent heat flux
65      - maintain snow precipitation unchanged (even if Tsf >=0).
66     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
67    
68    checkpoint52m_post
69    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
70      this does not change any of the results, because myIter=0 in swfrac always
71      lead to jwtype=2 (the default anyway), but the call makes little sense
72      as a default
73    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
74    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
75      atmospheric model (AIM) to use it ; add a "slab ocean" component.
76    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
77    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
78    o extending useSingleCpuIO option to work with new exch2 I/O format
79      - old-style, missing-tile I/O is still accessible by defining CPP
80        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
81    o monitor package can write to NetCDF files and/or STDOUT
82    o fix re-definition bug in MNC_GRID_INIT_ALL()
83    o doc/api_reference added
84      - a framework for building an API Reference Manual using all
85        the "protex" comments embedded in the code
86      - see pkg/generic_advdiff, pkg/mnc for examples
87    o MNC:
88      - make myThid the last argument for all subroutines
89      - new default for the grid files: NO halos
90      - add useMNC and other run-time flags
91      - separate per-file-group handling of the unlimited dimension
92      - early initialization of MNC w/ flags read at the eeboot stage
93        and lookup tables set in initialize_fixed
94      - write all MNC output to a freshly-created directory
95    o thermodynamics sea-ice (thsice) is now tested with testreport.
96    o test exp. advect_cs: use the standard cs32 grid ; update output.
97    o Added functionality to grdchk:
98      pick global i,j,k position (or nearest wet) where to perform check.
99    
100    checkpoint52l_post
101    o new land formulation:
102      a) use ground enthalpy as prognostic variable to ensure exact
103         energy conservation.
104      b) account for water temperature and for latent heat of freezing
105         in all processes (rain, run-off, ground storage)
106      c) compute surface and ground temperature implicitly.
107    o aim_v23 modification for new land model:
108      a) Treat separately land / ocean / sea-ice surface fluxes
109         to allow implicit computation of land & sea-ice surface temp.
110      b) add snow precipitation.
111    checkpoint52l_pre
112    
113    o fix problem (when 1 tile is empty) in min/max monitor.
114    o fix bug in timeAve (u,vZetatave in common block)
115    o no restoring terms under ice for pkg/seaice
116    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
117    o bug fix for pkg/seaice pickups
118    o change MNC call locations and add coordinate attributes
119    o mask vorticity at the corner ; affects global_ocean.cs output
120    o fix ini_curvilinear_grid ; test CS experiments with mpi
121    o aim.5l_cs: modify sea-ice fraction input file ; update output
122    o exf: Adding simple range check routine for exf fields after read
123    
124    checkpoint52k_post
125    o removed top-level directory "diags"
126      - we migrated these functions to pkg/timeave a long time ago
127    o fixed bug introduced in pkg/monitor
128    o accuracy ctrlprec = 32 insuffient for gradient checks using
129      averaged fields (I/O via cost_averages)
130      -> use ctrl.h in active_file*.F to control I/O precision.
131    o paramter list of CALL ADTHE_MAIN_LOOP
132    o added initial do_the_model_io to ecco
133    o set all ...Freq to zero after cost_final
134      taveFreq, dumpFreq, pChkptFreq
135    o MAIN and ECCO differentiability restored
136    
137    checkpoint52j_post
138    o fix nchklev in tamc.h for global_ocean...
139    o Bringing flow and store directives up-to-date
140    o Really weird thing!
141      call do_the_model_io from the_main_loop with parameters
142      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
143      TAF places a faulty re-call of initialise_varia
144      after cost_final call which should not be there!
145    checkpoint52j_pre
146    
147    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
148      error messages
149    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
150    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
151      debug output
152    o modfied mdsio_writefield.F to handle non-global files under exch2
153    o update AIM Cubed-Sphere exp (aim.5l_cs):
154      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
155    o update AIM Equatorial Channel exp:
156      use standard aim_v23 pkg and change the SST fields to be more realistic.
157    o globalFile now works with exch2
158    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
159      mon_vort3.F to make exch2 friendly with >1 tile per cube face
160    o limit timeave output for hi-res integrations
161    
162    checkpoint52i_post
163    o removed CPP_EEOPTIONS.h from verification/*/code
164    o updated the tiling for global_ocean_pressure
165    checkpoint52i_pre
166    
167    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
168      the old pkg/aim).
169    
170    checkpoint52h_pre
171    o shortened offending lines in exch2_send_rx?.template
172    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
173    o genmake2: add build & execute test for NetCDF code
174    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
175      old grid files, moved CPP_EEMACROS.h to pkg/exch2
176    o added useSingleCPUIO flag to monitor.F and mon_out.F
177    o added temporary hack for sea-ice dynamics on the cube:
178      metric terms are ignored and it is assumed that
179      there is no sea-ice on cube faces 1, 2, 4, and 5.
180    
181    checkpoint52f_post
182    o added exch2 cube routines to pkg/exch2
183    o modified hs94.cs-32x32x5 to use it
184    o added new grid files to hs94.cs-32x32x5
185    checkpoint52f_pre
186    
187    checkpoint52e_post
188    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
189      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
190    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
191      to work with implicit vertical advection and AB ;
192    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
193    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
194     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
195    checkpoint52e_pre
196    
197    o fix bug in impldiff when Nr=1 or Nr=2.
198    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
199    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
200    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
201      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
202    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
203    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
204    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
205    
206    checkpoint52d_post
207    o re-tiled many expts to allow comparison in multi-processor mode
208      - updated output accordingly
209      - changed hs94.128x64x5 to use intial T from file rather than use the
210        random number generator
211    o add infrastructure in model routines for fizhi and gridalt packages
212    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
213    o changes to permit hi-res, cubed-sphere, configuration
214      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
215      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
216      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
217        of surface winds for the cube
218      (A verification experiment, based on global_ocean.cs32x15, but with
219       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
220       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
221       complete with example surface forcing files and matlab scripts to look
222       at the output and compare it with that of global_ocean.cs32x15.)
223    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
224       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
225       to conform to the common rule.
226    o check-in the first version of the coupler + interfaces for multi-components
227       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
228       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
229       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
230       - ocean and atmos. share the same horizontal grid (no interpolation).
231       - exchanges between component and coupler is done in forward_step
232    o new verification experiment, cpl_aim+ocn:
233       coupled ocean - AIM atmosphere on cs32 grid.
234    
235    checkpoint52d_pre
236    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
237    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
238    
239    checkpoint52c_post
240    o Fixing OPTIONS files for use of exf:
241      - ALLOW_ECCO not needed
242      - ECCO_CPPOPTIONS.h should not be included from
243        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
244        as has been the case in the past
245      - All cal/exf related options are currently set in
246        single header file. Should remain so until we
247        agree on a consistent new policy.
248    o Removed all CPP options for cal package.
249      cal has no more CPP options.
250    o modified STOREs in GAD_ADVECTION
251    o corrected key comp. for passkey
252    
253    checkpoint52b_post
254    o new version: "thsice" of thermodynamic sea-ice pkg:
255     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
256     - modify fluxes but do not change theta directly;
257     - light cleaning of bulk_force pkg (still needed with thsice).
258     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
259       + output_thsice.txt to test thsice & bulk_force pkgs.
260    o put back grid & coriolis monitor output.
261    checkpoint52b_pre
262    
263    o call "do_the_model_io" at the beginning (=> dump initial state)
264    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
265    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
266      (need info on NUMBER_OF_PTRACERS)
267    o missing PTRACERS headers in some routines
268    o default tamc.h in pkg/autodiff supposed to crash
269      to ensure proper customization
270    
271    checkpoint52a_post
272    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
273      - moved surfaceTendencyTice from pkg/seaice to main code
274      - subroutine FREEZE_SURFACE now limits only surface temperature
275        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
276        => new output.txt for global_ocean.cs32x15 & global_with_exf
277      - keep the old version of FREEZE for backward compatibility;
278        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
279      - corresponding modifs for TAF directives
280    o added surface flux output variables to TIMEAVE_STATVARS
281    o time-averaged output for pkg/ptracers
282    o fix problem with ECCO-related divided adjoint
283      snapshot file was missing some ad-variables,
284      but no warning issued by TAF
285    
286    checkpoint52a_pre
287    o some bug fixes for #undef REAL4_IS_SLOW
288    
289    checkpoint52 = ecco_c52_e35
290    o after testing adjoints of checkpoint51u_post
291    
292    checkpoint51u_post
293    o this is the post-merge tag of the ecco-branch
294      (needs another clean checkout and re-testing)
295    o various natl_box_adjoint configs and results
296      but no input fields
297    o obcs adjoint not yet merged!
298    o adding ECCO global 1x1 and 2x2 degree configs
299    o updated/extended some store directives for seaice
300    o pkg/ecco now containes ecco-specific part of cost function
301    o top level routines the_main_loop, forward_step
302      supersede those in model/src/
303      previous input data.cost now in data.ecco
304      (new namelist ecco_cost_nml)
305    o in ctrl/ cleaned some cross-dependencies and updated CPP options
306    
307    checkpoint51t_post
308    o this is the pre-merge tag of the ecco-branch
309    
310    checkpoint51s_post
311    o cleanup: removed various obsolete #define-s
312    o pkg/grdchk
313      - renamed 'ph-grd 3' to 'grad-res'
314      - merged from ecco-branch
315        (remaining bug fixes for obcs gradient checks)
316      - additional high-precision output for testreport
317        (grep for 'precision_grdchk_result')
318    
319    checkpoint51r_post
320    o cleaned up or removed CPP_OPTIONS.h files
321    o updated results for some of the tests to reflect the new
322      optfiles (-ieee: -O0 instead of -O3)
323    
324    checkpoint51q_post
325    o cd_code:
326      - moved cd_scheme.F -> cd_code_scheme.F
327      - separate read_checkpoint from cd_code_ini_vars.F
328      - separated cd_code part from write_checkpoint
329      - updated AD_SOURCE, generated .flow
330      - added CD_CODE_VARS.h to the_main_loop
331      - Moving cd_code specific store dir.s to pkg/cd_code
332    o ctrl package totally restructured
333      - pack/unpack now optional and decoupled from
334        xx_/adxx_ I/O
335      - ctrl_pack/unpack cleaned
336        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
337      - confined inclusion of AD_CONFIG.h to where necessary.
338    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
339    
340    checkpoint51p_post
341    o create initial cd_code package
342      - WARNING: the initialization of fields within packages
343        is broken because INI_FIELDS (where READ_CHECKPOINT is
344        called) is called *before* PACKAGES_INIT_VARIABLES.
345        This seems to be backwards since
346        1) its important to initially zero the entire field including
347           the "halo" region
348        2) zeroing needs to be done *before* reading pickup info
349           and the pickup call might or might not happen in any
350           particular run
351      - this needs an overhaul for R2
352    o cleanup verification/*/code/GMREDI_OPTIONS.h
353    o cleanup testreport
354    
355    checkpoint51o_post
356    o bringing AD-related verif's up to date with genmake2
357      - carbon/
358      - global_ocean.90x40x15/
359      - hs.94.1x64x5/
360      - (front_relax/ )
361    o (more) consistent directory structure for AD-related verif.'s
362    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
363    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
364    o bug fix in find_alpha.F for MDJWF:
365      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
366        change rho -> rho-rhoConst
367      - replace call find_rho to find_rhonum
368    o initialisation of rFlx extended to full array (required by TAF)
369      and shifted to thermodynamics
370    o removed PTRACERS.h in ptracers routine
371    o added surfacetendencyPtr to S/R parameter list pracers_forcing
372    o Correcting initialisations for fVerU, fVerV.
373    o helping TAF to recognize dependency on kUp for
374      fVerU, fVerV
375    o Replacing delZ by delR in pkg/ctrl/
376    checkpoint51o_pre
377    
378    o undid all of cp51 pending some cleanups and discussion
379    o added the [#include "AD_CONFIG.h"] statement to all files that need
380       it for adjoint/tl #defines
381     o re-worked the build logic in genmake2 to support AD_CONFIG.h
382     o removed tools/genmake since it no longer works
383    
384    checkpoint51n_post
385    o modifications to make FREEZE flux visible to pkg/kpp
386      - moved surfaceTendencyTice from pkg/seaice to main code
387      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
388      - subroutine FREEZE now limits only surface temperature
389        (this means new output.txt for global_ocean.90x40x15,
390         global_ocean.cs32x15, and global_with_exf)
391    o added surface flux output variables to TIMEAVE_STATVARS
392    
393    checkpoint51n_pre
394    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
395    o added [#include "AD_CONFIG.h"] to all files that use the following
396      defines:
397      - ALLOW_ADJOINT_RUN
398      - ALLOW_TANGENTLINEAR_RUN
399      - ALLOW_ECCO_OPTIMIZATION
400    
401    checkpoint51m_post
402    o incorporating changes to get TAMC/TAF working in genmake2
403      - added new TAMC/TAF targets to the Makefile
404      - various cleanups related to package handling
405      - these changes should have no impact on the forward model
406    
407    checkpoint51l_post

480    o Added on-the-fly spatial interpolation capability
481        "USE_EXF_INTERPOLATION" to pkg/exf.
482      - This is a temporary Cartesian-grid hack until
483        the super-duper ESMF coupler becomes available.
484      - See verification/global_with_exf/README for usage example.
485      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

514    checkpoint51c_post
515    o introducing integer flag debugLevel
516      - debLevZero: suppress all output
517      - debLevA: standard
518      - debLevB: equivalent to current debugMode=.TRUE.
519    o introducing pathname variable mdsioLocalDir for mdsio
520      that can be specified at runtime
521      (relevant for cluster I/O to local disk)
522    `
523    >>>checkpoint51b_post
524    adjoint of ptracers
525    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM

539      - new pkgs: dic, gchem
540      - new subroutine in ptracers
541    o modify code for biogeo packages
542      - in model/src and pkg/ptracers
543    
544    checkpoint51
545    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
546      - autodiff, ctrl, exf, grdchk, seaice
547      kept separate packages
548      - cost, ecco, obcs
549    o updating verification/internal_wave, verification/lab_sea
550      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
551    
552    checkpoint50i_post
553    o Preparing next differentiable checkpoint and sync
554      of MAIN vs. ecco-branch
555      - 1st step: this one is differentiable
556      - 2nd step: next(! not this) checkpoint will have updated packages
557                  from ecco-branch)
558    
559    checkpoint50h_post
560    o new package "land": provide surface BC for AIM.
561    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
562    o AIM: use true log-P extrapolation for near surface temp (= as in
563        F.Molteni paper) ; update aim.5l_cs output.
564    o New variable in PARM03 for more flexible pickups
565    o somewhat cleaned package initialisation sequence for
566      ctrl/ cost/ ecco/ in packages_... routines
567    
568    checkpoint50g_post
569    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
570      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
571      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
572        made the default because of faster convergence than ADI
573    
574    checkpoint50f_post
575    o exf totally restructured
576      - replaced all exf_set_ routines by one generic exf_set_gen.F
577        and made sure it's still differentiable
578      - split exf_getffields.F into new exf_bulkformulae.F

590     o removed lots of single quotes from comments
591    
592    checkpoint50e_post
593    o make KPP work with PTRACERS
594     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
595       nearly a copy of kpp_transport_s
596     - there is no analogue to SurfaceTendencyS, so I have to use
597       gPtr(of the surface layer) instead
598    o add a new platform SunFire+mpi (SunFire 15000) to genmake
599    checkpoint50e_pre
600    
601    checkpoint50d_post
602    o change kpp output from multiple-record state files to single-record state
603      files analogous to write_state.F
604    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
605      analogous to the cg2d-related output.
606    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
607      so that writing to internal file fn (with length 512) fails.
608    checkpoint50d_pre
609    
610    checkpoint50c_post
611    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)

613    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
614    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
615    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
616    
617    checkpoint50c_pre
618    Merging from release1_p13:
619    o bug fix for pkg/seaice dynamic solver
620    o Added SEAICE_initialHEFF to pkg/seaice
621    
622    checkpoint50b_post
623    o store u*,v* in gU,V instead of in guNm1,gvNm1
624    o in order to put the momForcing out of the Adams-Bashforth:
625      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
626      to timestep.F
627    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
628    o re-generate output for highly sensitive test-exp:
629       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
630    
631    checkpoint50b_pre
632    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
633    o corrected CPP option mismatch in exf_Bulk... functions for case
634      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
635    
636    checkpoint50a_post
637    o Bug fix for merging between c50 and KPP.
638      ikey was passed from thermodynamics to kpp_calc via
639      common block rather than being recomputed in kpp_calc,
640      in contradiction with new key itdkey.
641      New key ikppkey created, and tamc.h headers updated.
642    
643    checkpoint50
644    - 2nd step of merge with ecco-branch:
645      merge changes in ecco-branch back into main trunk
646    - bug fix in find_alpha
647    - more storing in gmredi_calc_tensor.F, kpp_routines.F
648    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
649    - merged some sliced AD support routines
650    
651    checkpoint49
652    merged from ecco-branch:
653    o exf:
654      - Enable initialisation of forcing fields to constant
655        (runtime) values.
656      - in exf_getffields.F
657        Reduce i-/j-loop to interior domain, discarding overlaps.
658        That also fixes wrong TAF-key computations for key_1, key_2
659        with bulf formulae.
660      - exf_init.F modify #ifdef for exf_init_evap
661      - exf_getffieldrec.F, ctrl_getrec.F
662        The following INT-usages are not safe:
663          fldsecs  = int(fldsecs/fldperiod)*fldperiod
664          fldcount = int(fldsecs/fldperiod) + 1
665        and were modified.
666    o autodiff: checkpoint_lev...
667      - updated storing for bulk formulae (some arrays were missing)
668      - added state for seaice package
669      - synchronized with main branch
670    o DIVA:
671      Modif.s in
672      - the_main_loop.F
673      - the_model_main.F
674      and added cost_final_restore.F cost_final_store.F
675      o With these changes, it is possible to fully separate
676        the first forward run to compute the cost function (mdthe_main_loop)
677        and adjoint runs over individual DIVA intervals (adthe_main_loop)
678        into separate model executions.
679        This enables better tuning of DIVA to given queue sizes.
680      o Loss of cost function value in consecutive DIVA runs is
681        fixed by storing to 'costfinal' file.
682      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
683        beginning/end of adjoint integration is accounted for.
684      The current changes apply to TAF-1.4.26.
685      TAF has one remaining bug, requiring one manual change
686      (see MITgcm manual).
687    o cal: synchronized between MAIN and ecco-branch
688    
689    checkpoint48i_post
690    o Changes to restore differentiability of code w.r.t. previous tag
691      (mostly adding new routines to make list and replacing
692      pressure by totPhiHyd).
693    o Updated and merged grdchk package
694      - has both ADM and TLM checks
695      - works for single- and multi-proc.
696      - output cleaned
697      - worked successfully for parallel DIVA
698    o genmake:
699      - Adding -platform=SP4
700      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
701    o Modif. for DIVA:
702      ctrl_unpack should not be called in intermediate DIVA interval.
703      (similar thing would apply for active files such as
704      tbar, sbar, psbar, which should not be reinitialised;
705      only relevant for ecco-branch)
706    
707    checkpoint48h_post
708    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
709    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
710    o Added SEAICE_initialHEFF to pkg/seaice
711    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
712    
713    checkpoint48g_post
714    --- EOS:
715    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
716      store total Potential in totPhyHyd for diagnostics & EOS.
717    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
718    --- Pressure/geopotential gradient:
719    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
720    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
721      ( changes results of global_ocean_pressure )
722    o NLFS + z-coord.: add eta*Rho' contribution.
723    o accurate phiHyd when using interface-W at the middle between 2 centers
724     ( changes results of ideal_2D_oce )
725    o includes r* 2nd term in potential gradient.
726    
727    checkpoint48f_post
728    Merging from release1_p12:

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

755    checkpoint48e_post
756    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
757    o dynamics: change definition of computational domain & adapt mom_fluxform
758      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
759    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
760        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
761        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
762        global_ocean.90x40x15 global_with_exf global_ocean_pressure
763        inverted_barometer solid-body.cs-32x32x1
764      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
765    
766    checkpoint48d_post
767    o in preparation for r*:
768     a) use pre-computed gradient of hydrostatic potential:
769        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
770     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
771        => affects results of glob_oce_pressure (different truncation error)  
772      update output.txt of ideal_2D_oce & global_ocean_pressure
773    
774    checkpoint48d_pre
775    o in preparation for r*:
776      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
777      pass the 2 comp. of the grad. as arguments to momentum S/R.
778      but for the moment, only used if it does not change the results.
779    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
780    
781    checkpoint48c_post
782    Modifications in treatment of initial flux forcing controls
783    to avoid extra storing of flux fields.
784    
785    checkpoint48c_pre
786    o Added tidal_basin_2d experiment (currently 1D!)
787    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
788    
789    checkpoint48b_post
790    o r* coordinate added in #ifdef NONLIN_FRSURF block.
791     (modification to pressure gradient not yet implemented)
792    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
793      (for U & V) that are used for vertical advection of momentum.
794    
795    checkpoint48a_post
796    o In preparation for r*, use temp. array to compute vertical transport
797       in flux-form momentum pkg. => change results of few test-exp.
798      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
799                        lab_sea, natl_box & plume_on_slope
800    
801    checkpoint48
802    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
803    
804    checkpoint47j_post
805    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
806    o moved adexch from forward_step to addummy_in_stepping
807    o added exch in ctrl_map_...
808    o aveFreq.=0. at end of cost_final to avoid overwrite in
809      reverse checkpointing loop
810    o Yet more changes in gmredi:
811      * adgmredi_calc_tensor
812        avoiding all recomputation of gmredi_slope_limit
813      * adgmredi_x/y/rtransport
814        added flag for excessive storing to avoid recomp. of
815        u/v/rtans, dTdx/y/z
816        -> this is not really necessary and very memory-consuming
817      * adgmredi_slope_psi:
818        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
819      * gmredi_slope_limit
820        re-activated full calculation of taperfct for case 'ac02'
821    o updating verification/ adjoints of carbon, global_ocean.90x40x15
822    
823    checkpoint47i_post
824    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
825    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
826      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
827    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
828    o gmredi: fix few bugs.
829    
830    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
831    This will be a good checkpoint to plug into the ecco-branch.
832    o few modif.'s to get latest version adjointed
833      (mainly kick out code in ini_linear_phisurf)
834    o modif's to run adjoint with exactConserv
835    o case GM_BOLUS_ADVEC should be cleaned
836      S/R gmredi_slope_psi should be cleaned
837    o verification/carbon now has exactConserv=.TRUE.
838    
839    checkpoint47g_post
840    o time-average AIM output: becomes independent from statvars time-average
841      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
842    o After TAF bug fix:
843      Tested adjoint of gmredi package.
844      Tests were done with checkpoint47 rather than with latest
845      checkpoint47f_post since the latter is broken for the adjoint
846      verification/carbon/ contains both ADM and TLM gradient checks.
847    Here they are, before they get changed/lost/stolen.
848    Mostly modif.'s to fix numerical sensitivities.
849    Gradient checks OK for
850    - GM_taper_scheme:
851      * clipping
852      * ac02
853      * linear
854      * glw91
855      * dm95
856      * ldd97
857    - GMREDI_OPTIONS:
858      * GM_VISBECK_VARIABLE_K
859      * GM_NON_UNITY_DIAGONAL
860      * GM_EXTRA_DIAGONAL
861      * GM_BOLUS_ADVEC
862    in conjunction with data.gmredi parameters to be checked in
863    in a few minutes under verification/carbon/code/
864    
865    checkpoint47f_post
866    Merging from release1_p10:
867    o modifications for using pkg/exf with pkg/seaice
868      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
869        and SEAICE_EXTERNAL_FLUXES
870      - pkg/exf CPP options EXF_READ_EVAP and
871        EXF_NO_BULK_COMPUTATIONS
872      - usage examples are Experiments 8 and 9 in
873        verification/lab_sea/README
874      - verification/lab_sea default experiment now uses
875        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
876    
877    checkpoint47e_post
878    o created a tag prior to creating a branch
879    
880    checkpoint47d_post
881    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
882      at the bottom boundary had an erroneous half slip boundary condition
883    o added bottom drag and no slip boundary condition capabilities to
884      oceanic pressure coordinates code
885    o added new verification experiment global_ocean_pressure, this experiment is
886      also described in the tutorial section of the manual
887    checkpoint47d_pre
888    
889    checkpoint47c_post
890    o Added a verification experiment for a global cubed-sphere ocean run
891      -  verification/global_ocean.cubed32x32x30
892      -  uses pkg/therm_seaice and pkg/bulk_forcing
893    
894    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
895    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
896      when using P-coordinate; only implemented for atmospheric config.
897    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
898      NOTES: requires option NONLIN_FRSURF to be "#define".
899    o update advect_xz/results/output.txt (left from checkpoint44g_post)
900    
901    checkpoint47b_post
902    Merging from release1_p9:
903    o pkg/seaice
904      - removed GOTO's and added taf directives
905      - double precision constants to reduce the g77 (Linux)
906        to F77 (SGI) differences reported in release1_p8
907    o tools/genmake
908      - added SGI options
909    o verification/testscript
910      - updated to that of checkpoint47a_post
911    o verification/global_ocean.90x40x15/input/eedata
912      - modified for SGI f77 compatibility
913    o verification/lab_sea
914      - added description of sea-ice model
915      - added missing matlab routines
916      - added test of thermodynamics parallelization
917    
918    checkpoint47a_post
919    o new pkg: aim_v23
920     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
921       for now, keep the same surface forcing as before.
922     - Part-Cell implemented into AIM; check that Heat & Water are conserved
923     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
924     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
925    o add diagnostic of surface correction term in monitor output
926    
927    o bulk_force and therm_seaice
928    - Two packages:  bulk_force (Bulk forcing)
929      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
930    - Earlier integration from Stephaine Dutkiewicz
931      and Patrick Heimbach.
932    - Two ifdef statements for compile time,
933       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
934    
935    checkpoint47
936    differentiable version of checkpoint46n_post
937    o bug fix in quasihydrostaticterms
938    o * "clean" adjoint code (in terms of extensive recomputations)
939        can now be obtained for all GMREDI options (i.e. for
940        - GM_VISBECK_VARIABLE_K
941        - GM_NON_UNITY_DIAGONAL
942        - GM_EXTRA_DIAGONAL
943        - GM_BOLUS_ADVEC )
944      * However, wrong gradient check problem remains unsolved.
945      * New CPP options have been introduced for different
946        tapering schemes
947    o external_fields_load now part of differentiation list
948    o pressure needs multiple storing;
949      would be nice to have store_pressure at beginning or
950      end of forward_step, e.g. by having phiHyd global (5-dim.)
951      (NB: pressure is needed for certain cases in find_rho,
952      which is also invoked through convective_adjustment).
953    o recomputations in find_rho for cases
954     'JMD95'/'UNESCO' or 'MDJWF' are OK.
955    o #define ATMOSPHERIC_LOADING should be differentiable
956    o ini_forcing shifted to begining of initialise_varia
957    o Incorporating QNVS line search routines into MITgcm
958      (this is separate code, and therefore not under pkg)
959      lsopt/, optim/
960    o Updated verification/carbon/
961      - #define GM_VISBECK_VARIABLE_K
962      - GM_taper_scheme    = 'ldd97'    
963    
964    checkpoint46n_post
965    Merging from release1_p8:
966    o verification/natl_box:
967      updating new external_fields_load routine
968    o New package: pkg/seaice
969      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
970      The sea-ice code is based on Hibler (1979-1980).
971      Two sea-ice dynamic solvers, ADI and LSR, are included.
972      In addition to computing prognostic sea-ice variables and diagnosing
973      the forcing/external data fields that drive the ocean model,
974      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
975      The implied surface heat flux is then stored in variable
976      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
977      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
978      non-local transport term.  Because this call precedes model
979      thermodynamics, temperature under sea-ice may not be "exactly" at
980      the freezing point by the time theta is dumped or time-averaged.
981      N.B.: fairly large differences in accuracy occur across
982            different platforms/compilers; comparison between
983            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
984            generated output gives:
985       T           S           U           V
986      C D M    c        m  s        m  s        m  s        m  s
987      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
988      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
989      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
990    
991      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
992    o GAD:
993      - generated new common blocks to account for call of
994        same gad routines with differing traceridentities
995        (needed to modify tracerIdentity indices in GAD.h)
996      - generated separate common blocks for case useCubedSphereExchange
997        (Department of Futurology)
998      - parameter lists to gmredi_?transport: added tracerIdentity
999      - added new key indices to tamc.h
1000    o external_fields_load:
1001      - added this routine to TAF list
1002      - needed to make some common blocks global and additional storing
1003        along the same lines as exf package (checkpoint_lev?_directives.h)
1004    o exf:
1005      updated external forcing package
1006      - bug fixes carried over from ecco-branch
1007        (missing OBCS_OPTIONS.h in two routines)
1008      - enable easy to use "no forcing".
1009      - added exf I/O for atmospheric loading
1010      - added exf I/O for runoff data
1011      - transfered scaling between exf <-> MITgcm to exf namelist
1012    o Adding new verification experiment global_with_exf.
1013      This verification experiment is almost identical to the
1014      global_ocean.90x40x15 experiment, except that it uses
1015      the exf (and cal) package instead of the
1016      external_fields_load routine (cf README file).
1017    
1018    checkpoint46m_post
1019    o modified testscript to return -- when there are no lines of "%MON" output
1020    o added new flag "quasiHydrostatic" for QH mode
1021      and new routine quasihydrostaticterms()
1022    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
1023      New routine: mom_u_coriolis_nh()
1024    o fixed sign of non-hydrostatic metric terms in u and v equations.
1025      Depend on correct sign of gravitySign.
1026    o added work.pc* to .cvsignore in aim directories using ifc
1027    o introduced flag for controllin non-hydrostatic metric terms
1028    o removed gravitySign from PARM04
1029    o switched to g77/ifc from pgf77 in aim experiments
1030    
1031    checkpoint46l_post
1032    o made convective adjustment work with pressure coordinates:
1033     - changed the direction of k-loop in convective_adjustment.F for the
1034       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
1035     - adjusted the reference pressure k-index in convective_adjustment.F
1036     - adjusted the convection condition in convect.F (in analogy to
1037       calc_ivdc.F)
1038     - convective_adjustment no longer computes anything on the halos
1039     - removed the warnings about negative salinity from find_rho.F and
1040       find_alpha.F; instead the new routine look_for_neg_salinity, called
1041       at the beginning of find_rho, find_alpha, and find_beta, does a
1042       check of the entire slice, if CPP-option
1043       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
1044    checkpoint46l_pre
1045    
1046    checkpoint46k_post
1047    o fixed the verification/global_ocean.90x40x15 experiment:
1048     - new bathymetry (the world according to A., JMC, and M.)
1049     - new initial fields and forcing fields (*.bin files)
1050     - new POLY3.COEFFS (for the next release one should switch to a full
1051       equation of state: JMD95P or MDJWF)
1052     - fixed several errors and redundancies in the data file
1053     - experiment uses looped cells
1054     - added matlab directory with diagnostic scripts for plotting of output
1055    
1056    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1057     - read AIM physics parameters from a file (data.aimphys)
1058     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1059    
1060    checkpoint46j_post
1061    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1062    o move wVel computation at the end of the time step, in S/R integr_continuity
1063    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1064    o update timeave pkg for wVel diagnostic.
1065    checkpoint46j_pre
1066    
1067    checkpoint46i_post
1068    o Clean up AIM package (and keep the results unchanged):
1069      include CPP_OPTION and use IMPLICT NONE in all routines ;
1070      declare all the variables _RL ; use _d 0 for all numerical constants.
1071      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1072    
1073    checkpoint46h_post
1074    o cleaned up the use of rhoNil and rhoConst.
1075      - rhoNil should only appear in the LINEAR equation of state, everywhere
1076        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1077        and the dynamical equations are all divided by rhoConst
1078    o introduced new parameter rhoConstFresh, a reference density of fresh
1079      water, to remove the fresh water flux's dependence on rhoNil. The default
1080      value is 999.8 kg/m^3
1081    o cleanup up external_forcing.F and external_forcing_surf.F
1082      - can now be used by both OCEANIC and OCEANICP
1083    checkpoint46h_pre
1084    
1085     Added code to convert surface volume flux (fresh water) into
1086     a mass flux when using P coordinates in the ocean (OCEANICP).
1087     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1088    
1089    checkpoint46g_post
1090    o Include a new diagnostic variable phiHydLow for the ocean model
1091      - in z-coordinates, it is the bottom pressure anomaly
1092      - in p-coordinates, it is the sea surface elevation
1093      - in both cases, these variable have global drift, reflecting the mass
1094        drift in z-coordinates and the volume drift in p-coordinates
1095      - included time averaging for phiHydLow, be aware of the drift!
1096    o depth-dependent computation of Bo_surf for pressure coordinates
1097      in the ocean (buoyancyRelation='OCEANICP')
1098      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1099        Theta, Salinity, and Pressure in the parameter list. This routine is
1100        presently contained in find_rho.F. This routine does not give the
1101        correct density for 'POLY3', which would be a z-dependent reference
1102        density.
1103    o cleaned up find_rho
1104      - removed obsolete 'eqn' from the parameter list.
1105    o added two new verification experiments: gop and goz
1106      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1107    checkpoint46g_pre
1108    
1109    checkpoint46f_post
1110    o Enable tangent linear (forward mode) gradient checks:
1111      - extended active file handling to g_... files
1112      - added TANGENT_SIMULATION to theSimulationMode
1113      - extended grdchk package accordingly
1114    o added tangent linear setup in verification/carbon/code_ftl
1115    o added adjoint setup in verification/front_relax/code_ad
1116    
1117    checkpoint46e_post
1118    o Added new equation of state -> MDJWF
1119      - EOS of McDougall et al., 2002, JAOT, submitted
1120      - caveat: the equation of state is only valid for a smaller (more
1121        realistic?) range of values than JMD95P/Z and UNESCO
1122      - added masks to the calculation of pressure in store_pressure
1123      - added more check values for density in check_eos (ini_eos.F), some of
1124        the old check values are out of the range of the MDJWF-eos, so don't
1125        expect perfect matches for those
1126    checkpoint46e_pre
1127    
1128    checkpoint46d_post
1129    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1130      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1131      case of pressure coordinates. eosType='JMD95Z' in
1132      combination with buoyancyRelation='OCEANICP' now causes an error.
1133    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1134      in find_alpha/beta.
1135    checkpoint46d_pre
1136    
1137    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1138      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1139    
1140    checkpoint46c_post
1141    o Changes necessary for ocean in p-coordinates
1142     -  Added new buoyancy relation = 'OCEANICP'
1143     -  Added new parameters = gravitySign (this used to be contained inside
1144        the factor dRdZ which I added when we first switched to R coordinates).
1145     X GM/Redi is not compatible (yet)
1146     X bottom drag and no-slip need to be debugged.
1147    checkpoint46c_pre
1148    
1149    checkpoint46b_post
1150    o Added new equation of state -> JMD95Z and JMD95P
1151      - EOS of Jackett and McDougall, 1995, JAOT
1152      - moved all EOS parameters into EOS.h
1153      - new routines ini_eos.F, store_pressure.F
1154    o Added UNESCO EOS, but not recommended because it requires
1155      in-situ temperature (see JMD95)
1156    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1157      unesco.f to be used with POLY3
1158    checkpoint46b_pre
1159    
1160    checkpoint46a_post
1161    o Added (atmospheric) pressure loading
1162      - new field in FFIELDS.h, etc...
1163      - new cpp flag ATMOSPHERIC_LOADING
1164    o Changed hFacC to _hFacC in calc_phi_hyd.F
1165    o Added SHORTWAVE_HEATING to some files for consistency
1166    checkpoint46a_pre
1167    
1168    checkpoint46
1169    further merges from release1_p5
1170    o new ctrl package
1171      - adopted from ECCO environment to enable optimization
1172      - added Eliassen Palm fluxes to controls
1173    o added Eliassen Palm flux controls to gradient check package
1174    o cost package
1175      - Compatible with new ctrl package
1176      - added Eliassen Palm cost hooks
1177      - modif's of existing cost functions
1178    o Adjoint-related bug fixes in kpp:
1179      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1180      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1181    o autodiff package
1182      - flow directives:
1183        + new for S/R do_the_model_io
1184        + enhanced for S/R checkpoint
1185        + new gmredi.flow
1186      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1187        disable adcommon.h/g_common.h by default.
1188      - fixed problem for adjoint of global_max
1189    o modified verification/carbon/
1190    o New setup for adjoint of global_ocean
1191    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1192    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1193    o incorporated hooks for sponge layer code (external_forcing.F)
1194    
1195    checkpoint45d_post
1196    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1197    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1198      (affects plume_on_slope "cg2d" output)
1199    o add new parameter deltaTfreesurf for free-surface time stepping
1200    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1201    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1202    o change phiMin in exp1 (to agree with documentation)
1203    o add new flags:
1204     - T,S forcing inside/outside Adams-Bashforth
1205     - turn off temp,salt advection and/or forcing
1206     - for each tracer, define internal flag for multiDimAdvection & A-B
1207    o monitor: change definition of KE to check conservation of Energy
1208    
1209    checkpoint45c_post
1210    o Removed f90 comments ("!")
1211    o Modified initialisations to enable exf package for MITgcm
1212      (without invoking ECCO_PACKAGE).
1213    o modifications to gradient check package (Martin Losch)
1214      - enable centered differences
1215      - modified format of standard output
1216    
1217    checkpoint45b_post
1218    o cleaned exchange calls in cg2d
1219    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1220    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1221      to configure barotropic setup (Martin Losch)
1222    o moved some initialisations within bi,bj loop in dynamics
1223      (TAF flow dependency)
1224    o in initialise_varia, moved call packages_init_variables
1225      before convective_adjustment_init
1226      (corresponding adjustment of TAF tape initialisation).
1227    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1228    
1229    checkpoint45a_post
1230    o compute Rho over the whole domain (extend iMin,jMin indices)
1231    o specific exchange for X-slice domain (case Ny=1)
1232    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1233    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1234    
1235    checkpoint44h_post = checkpoint45
1236    o Fix to restore differentiability:
1237      place at which packages_init_variables is called in
1238      initialise_varia is crucial for reverse control flow.
1239    o modifications in GMRedi to enable stable adjoint
1240      (corresponding modif's in thermodynamics, dynamics)
1241    o added missing hook for sponge layer code in external_forcing

1248    
1249    checkpoint44h_pre
1250    o vertical grid option: allow to put the Interface at the middle between
1251      2 cell-centers ; replace delZ in pkg/kpp by drF.
1252    o GM Advective form: Tracers are advected using the residual transport (=
1253      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1254    
1255    checkpoint44g_post
1256    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1257      results) ; ifdef missing in thermodynamics.F
1258    
1259    checkpoint44f_pre,checkpoint44f_post
1260    o added PTRACERS package
1261      This allows an arbitrary number of passive tracers to be integrated
1262      forward simultaneously with the dynamicaly model.
1263      + Implemented so far:
1264        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1265        - I/O and checkpointing
1266        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1267      + Not implemented so far:
1268        - KPP
1269        - OBCS
1270      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1271        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1272        line in data.pkg.
1273      + This package is disabled by default since it increases storage.
1274    
1275    
1276    o testscript: added -cleanup option
1277    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter

1279    
1280    checkpoint44e_pre,post
1281    o re-wrote convective adjustment to use pre-calculated weights
1282      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1283      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1284      Original calls to convect() still in place.

1287    o added missing EXCLUDE_MONITOR flags
1288    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi

1292      plus resetting for case SunOS
1293    o added timer_stats.c routine for IBM SP3
1294    o removed variables in dynamics

1297    
1298    o real fresh water flux implemented with non-linear free-surface.
1299    
1300    chkpt44c_pre,post
1301    o few fix (mask in shap_s2, EmPmR in external_field_load,
1302      USE_NATURAL_BCS in solve_for_P);
1303    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1304    
1305    checkpoint44b_pre/_post
1306    o merge of relevant stuff from the ecco-branch:
1307      - genmake: removed $S64 overwrite for case SunOS
1308      - pkg/exf: update and corrections for field swapping and obcs

1334    checkpoint42
1335      Fixed AD-related problems:
1336    o Store directives up-to-date with re-arranged Adams-Bashforth
1337      (mainly thermodynamics.F)
1338    o New store directives for multi-dim. advection schemes
1339      * new CPP flag ALLOW_MULTI_DIM_ADVECTION

1368      
1369    checkpoint40pre8
1370    o new package rw/
1371      Added method for dumping intermediate local arrays:
1372      mdsio_writetile - same as mdsio_writefield except works from inside
1373                        bi,bj loop
1374      mdsio_writelocal - same as mdsio_writetile except works for local
1375                         arrays
1376      write_local_r? - higher-level wrapper for mdsio_writelocal
1377      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1378      Example given at end of mom_vecinv.F that dumps some local arrays.
1379    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1380      control flux-form versus vector invariant code.
1381      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1382      or genmake -DISABLE ...
1383    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1384      (additional storing is now needed for case vecinv;
1385      currently nothing implemented to switch this storing off
1386      in case fluxform is used since no CPP flag available).
1387    
1388    checkpoint40pre7
1389    o bug fix in dynamics.F
1390      calc_viscosity called before k=1,Nr loop.

1401    o bug fix in gmredi_slope_limit for ldd97
1402    
1403    checkpoint40pre5
1404    o proper initialization of Adams-Bashforth time stepping
1405      + uses forward step for very first step of model (iter=0)
1406    o re-generated *all* output since almost all output is modified by this
1407      change (sorry but we've been putting this one off for about 2 years)
1408      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1409        *not* regenerated since they are already out of date and I don't
1410        want to create the impression that they are suddenly working.
1411    o removed KAP stuff for DEC's
1412    o modified/added many .cvsignore files in */code and */input
1413    o added new expt "solid-body.cs-32x32x1"
1414      + this uses an alternative form of ini_curvilinear_grid.F which
1415        is not necessarily any better than the current one...
1416    
1417    checkpoint40pre4
1418    o added re-initialisations of utrans,vtrans,rtrans in
1419      calc_common_factors which are crucial for TAF.

1443     o Included following packages:
1444       cal: calendar
1445       exf: external forcing
1446       ecco: essential routines to control use of cal, exf
1447             (NB: this is not the full ECCO environment)
1448     o disabled some packages by default in genmake
1449    
1450    checkpoint38
1451     o see notes_c37_adj.txt
1452     o corrected wrong layer index in external_forcing_t
1453     o replaced the_main_loop/forward_step by the_main_loop
1454     o removed forceoutput from write_state
1455       (replaced criteria for initial/final state)
1456     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1457    
1458    checkpoint37
1459     o mdsio.F routine split and packaged in pkg/mdsio
1460       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1461        used unless genmake -disable=mdsio)
1462     o allow a more precise surface-geopotential gradient for the atmosphere
1463       taking into account the change in space of Alpha (=1/rho) at the surface.
1464     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1465       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1466     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1467       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1468       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1469     o Time-Average diagnostics defined as a pseudo package "timeave".
1470     o pickup files : old pickup (before c35) did not work with new code (c35
1471       and after) unless activating 2 commented lines in initialise-varia.
1472     o Non-Hydrostatic pickup file Pb fixed.
1473     o bug with Rigid-lid version (since c35) fixed.  
1474    
1475  checkpoint36  checkpoint36
1476   o implement Crank-Nirotropic time-stepping   o implement Crank-Nickelson barotropic time-stepping
