3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    o MNC:
6      - make myThid the last argument for all subroutines
7      - new default for the grid files: NO halos
8      - add useMNC run-time flag
9    o thermodynamics sea-ice (thsice) is now tested with testreport.
10    o test exp. advect_cs: use the standard cs32 grid ; update output.
11    
12    checkpoint52l_post
13    o new land formulation:
14      a) use ground enthalpy as prognostic variable to ensure exact
15         energy conservation.
16      b) account for water temperature and for latent heat of freezing
17         in all processes (rain, run-off, ground storage)
18      c) compute surface and ground temperature implicitly.
19    o aim_v23 modification for new land model:
20      a) Treat separately land / ocean / sea-ice surface fluxes
21         to allow implicit computation of land & sea-ice surface temp.
22      b) add snow precipitation.
23    checkpoint52l_pre
24    
25    o fix problem (when 1 tile is empty) in min/max monitor.
26    o fix bug in timeAve (u,vZetatave in common block)
27    o no restoring terms under ice for pkg/seaice
28    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
29    o bug fix for pkg/seaice pickups
30    o change MNC call locations and add coordinate attributes
31    o mask vorticity at the corner ; affects global_ocean.cs output
32    o fix ini_curvilinear_grid ; test CS experiments with mpi
33    o aim.5l_cs: modify sea-ice fraction input file ; update output
34    o exf: Adding simple range check routine for exf fields after read
35    
36    checkpoint52k_post
37    o removed top-level directory "diags"
38      - we migrated these functions to pkg/timeave a long time ago
39    o fixed bug introduced in pkg/monitor
40    o accuracy ctrlprec = 32 insuffient for gradient checks using
41      averaged fields (I/O via cost_averages)
42      -> use ctrl.h in active_file*.F to control I/O precision.
43    o paramter list of CALL ADTHE_MAIN_LOOP
44    o added initial do_the_model_io to ecco
45    o set all ...Freq to zero after cost_final
46      taveFreq, dumpFreq, pChkptFreq

48    
49    checkpoint52j_post
50    o fix nchklev in tamc.h for global_ocean...
51    o Bringing flow and store directives up-to-date
52    o Really weird thing!
53      call do_the_model_io from the_main_loop with parameters
54      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
55      TAF places a faulty re-call of initialise_varia
56      after cost_final call which should not be there!
57    checkpoint52j_pre
58    
59    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
60      error messages
61    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
62    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating

65    o update AIM Cubed-Sphere exp (aim.5l_cs):
66      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
67    o update AIM Equatorial Channel exp:
68      use standard aim_v23 pkg and change the SST fields to be more realistic.
69    o globalFile now works with exch2
70    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
71      mon_vort3.F to make exch2 friendly with >1 tile per cube face

76    o updated the tiling for global_ocean_pressure
77    checkpoint52i_pre
78    
79    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
80      the old pkg/aim).
81    
82    checkpoint52h_pre
83    o shortened offending lines in exch2_send_rx?.template
84    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
85    o genmake2: add build & execute test for NetCDF code
86    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
87      old grid files, moved CPP_EEMACROS.h to pkg/exch2
88    o added useSingleCPUIO flag to monitor.F and mon_out.F
89    o added temporary hack for sea-ice dynamics on the cube:
90      metric terms are ignored and it is assumed that
91      there is no sea-ice on cube faces 1, 2, 4, and 5.
92    
93    checkpoint52f_post
94    o added exch2 cube routines to pkg/exch2
95    o modified hs94.cs-32x32x5 to use it
96    o added new grid files to hs94.cs-32x32x5
97    checkpoint52f_pre
98    
99    checkpoint52e_post
100    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
101      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
102    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
103      to work with implicit vertical advection and AB ;
104    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
105    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
106     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
107    checkpoint52e_pre
108    
109    o fix bug in impldiff when Nr=1 or Nr=2.
110    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
111    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
112    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
113      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure

117    
118    checkpoint52d_post
119    o re-tiled many expts to allow comparison in multi-processor mode
120      - updated output accordingly
121      - changed hs94.128x64x5 to use intial T from file rather than use the
122        random number generator
123    o add infrastructure in model routines for fizhi and gridalt packages
124    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
125    o changes to permit hi-res, cubed-sphere, configuration
126      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
127      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
128      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
129        of surface winds for the cube
130      (A verification experiment, based on global_ocean.cs32x15, but with
131       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
132       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
133       complete with example surface forcing files and matlab scripts to look
134       at the output and compare it with that of global_ocean.cs32x15.)
135    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
136       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
137       to conform to the common rule.
138    o check-in the first version of the coupler + interfaces for multi-components
139       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
140       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
141       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
142       - ocean and atmos. share the same horizontal grid (no interpolation).
143       - exchanges between component and coupler is done in forward_step
144    o new verification experiment, cpl_aim+ocn:
145       coupled ocean - AIM atmosphere on cs32 grid.
146    
147    checkpoint52d_pre
148    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
149    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
150    
151    checkpoint52c_post
152    o Fixing OPTIONS files for use of exf:
153      - ALLOW_ECCO not needed
154      - ECCO_CPPOPTIONS.h should not be included from
155        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
156        as has been the case in the past
157      - All cal/exf related options are currently set in
158        single header file. Should remain so until we
159        agree on a consistent new policy.
160    o Removed all CPP options for cal package.
161      cal has no more CPP options.
162    o modified STOREs in GAD_ADVECTION
163    o corrected key comp. for passkey
164    
165    checkpoint52b_post
166    o new version: "thsice" of thermodynamic sea-ice pkg:
167     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
168     - modify fluxes but do not change theta directly;
169     - light cleaning of bulk_force pkg (still needed with thsice).
170     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
171       + output_thsice.txt to test thsice & bulk_force pkgs.
172    o put back grid & coriolis monitor output.
173    checkpoint52b_pre
174    
175    o call "do_the_model_io" at the beginning (=> dump initial state)
176    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
177    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
178      (need info on NUMBER_OF_PTRACERS)
179    o missing PTRACERS headers in some routines
180    o default tamc.h in pkg/autodiff supposed to crash
181      to ensure proper customization
182    
183    checkpoint52a_post
184    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
185      - moved surfaceTendencyTice from pkg/seaice to main code
186      - subroutine FREEZE_SURFACE now limits only surface temperature
187        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
188        => new output.txt for global_ocean.cs32x15 & global_with_exf
189      - keep the old version of FREEZE for backward compatibility;
190        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
191      - corresponding modifs for TAF directives
192    o added surface flux output variables to TIMEAVE_STATVARS

202    o after testing adjoints of checkpoint51u_post
203    
204    checkpoint51u_post
205    o this is the post-merge tag of the ecco-branch
206      (needs another clean checkout and re-testing)
207    o various natl_box_adjoint configs and results
208      but no input fields
209    o obcs adjoint not yet merged!
210    o adding ECCO global 1x1 and 2x2 degree configs
211    o updated/extended some store directives for seaice
212    o pkg/ecco now containes ecco-specific part of cost function
213    o top level routines the_main_loop, forward_step
214      supersede those in model/src/
215      previous input data.cost now in data.ecco
216      (new namelist ecco_cost_nml)
217    o in ctrl/ cleaned some cross-dependencies and updated CPP options
218    
219    checkpoint51t_post
220    o this is the pre-merge tag of the ecco-branch
221    
222    checkpoint51s_post

224    o pkg/grdchk
225      - renamed 'ph-grd 3' to 'grad-res'
226      - merged from ecco-branch
227        (remaining bug fixes for obcs gradient checks)
228      - additional high-precision output for testreport
229        (grep for 'precision_grdchk_result')
230    
231    checkpoint51r_post
232    o cleaned up or removed CPP_OPTIONS.h files
233    o updated results for some of the tests to reflect the new
234      optfiles (-ieee: -O0 instead of -O3)
235    
236    checkpoint51q_post
237    o cd_code:
238      - moved cd_scheme.F -> cd_code_scheme.F
239      - separate read_checkpoint from cd_code_ini_vars.F
240      - separated cd_code part from write_checkpoint
241      - updated AD_SOURCE, generated .flow
242      - added CD_CODE_VARS.h to the_main_loop
243      - Moving cd_code specific store dir.s to pkg/cd_code
244    o ctrl package totally restructured
245      - pack/unpack now optional and decoupled from
246        xx_/adxx_ I/O
247      - ctrl_pack/unpack cleaned

249      - confined inclusion of AD_CONFIG.h to where necessary.
250    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
251    
252    checkpoint51p_post
253    o create initial cd_code package
254      - WARNING: the initialization of fields within packages
255        is broken because INI_FIELDS (where READ_CHECKPOINT is
256        called) is called *before* PACKAGES_INIT_VARIABLES.
257        This seems to be backwards since
258        1) its important to initially zero the entire field including
259           the "halo" region
260        2) zeroing needs to be done *before* reading pickup info
261           and the pickup call might or might not happen in any
262           particular run
263      - this needs an overhaul for R2
264    o cleanup verification/*/code/GMREDI_OPTIONS.h
265    o cleanup testreport
266    
267    checkpoint51o_post
268    o bringing AD-related verif's up to date with genmake2

272      - (front_relax/ )
273    o (more) consistent directory structure for AD-related verif.'s
274    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
275    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
276    o bug fix in find_alpha.F for MDJWF:
277      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
278        change rho -> rho-rhoConst
279      - replace call find_rho to find_rhonum
280    o initialisation of rFlx extended to full array (required by TAF)
281      and shifted to thermodynamics
282    o removed PTRACERS.h in ptracers routine
283    o added surfacetendencyPtr to S/R parameter list pracers_forcing
284    o Correcting initialisations for fVerU, fVerV.
285    o helping TAF to recognize dependency on kUp for
286      fVerU, fVerV

298      - moved surfaceTendencyTice from pkg/seaice to main code
299      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
300      - subroutine FREEZE now limits only surface temperature
301        (this means new output.txt for global_ocean.90x40x15,
302         global_ocean.cs32x15, and global_with_exf)
303    o added surface flux output variables to TIMEAVE_STATVARS
304    
305    checkpoint51n_pre
306    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

326    checkpoint51l_pre
327    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
328    o enable to apply restoring on S & T only in a latitude band.
329    o update output (external_forcing_surf modif. change truncation errors)
330       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
331    
332    checkpoint51k_post
333    o change default to: useNHMTerms=.FALSE.
334     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
335       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5

359    
360    checkpoint51i_post
361    o merge of the branch-genmake2

415      (instead of the string length) when the string. char is empty
416    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
417    o modif's to restore TAMC compatibility
418      - avoid "_d" constructs in PARAMETER declarations
419      - avoid interrupting lines by comment lines
420    o Use cluster local disks for purely local I/O
421      vs. globally visible disks needed for ctrl stuff
422      (merged from ecco-branch)
423      - new active_file_loc... and mdsio_..._loc routines
424      - affected packages: autodiff, ctrl, grdchk, mdsio
425    
426    checkpoint51c_post
427    o introducing integer flag debugLevel
428      - debLevZero: suppress all output
429      - debLevA: standard
430      - debLevB: equivalent to current debugMode=.TRUE.
431    o introducing pathname variable mdsioLocalDir for mdsio
432      that can be specified at runtime
433      (relevant for cluster I/O to local disk)
434    `
435    >>>checkpoint51b_post
436    adjoint of ptracers
437    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
438    o extended state in checkpoint_lev?, etc.
439    o alternative ctrl/cost with tr1 or ptracer
440    o new comlev1_bibj_ptracers
441    o new ptracers.flow
442    o made ptracers_forcing same as external_forcing_s
443    o added verification for adjoint with ptracers
444      - adm. grdchk fail so far
445      - tlm. grdchk OK
446      - checked tapelev/comlev recomputations: OK
447    <<<checkpoint51b_pre
448    
449    checkpoint51a_post
450    o added code for biogeochemistry package
451      - new pkgs: dic, gchem
452      - new subroutine in ptracers
453    o modify code for biogeo packages
454      - in model/src and pkg/ptracers
455    
456    checkpoint51
457    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
458      - autodiff, ctrl, exf, grdchk, seaice
459      kept separate packages
460      - cost, ecco, obcs
461    o updating verification/internal_wave, verification/lab_sea
462      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
463    
464    checkpoint50i_post
465    o Preparing next differentiable checkpoint and sync
466      of MAIN vs. ecco-branch
467      - 1st step: this one is differentiable
468      - 2nd step: next(! not this) checkpoint will have updated packages
469                  from ecco-branch)
470    
471    checkpoint50h_post
472    o new package "land": provide surface BC for AIM.
473    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
474    o AIM: use true log-P extrapolation for near surface temp (= as in
475        F.Molteni paper) ; update aim.5l_cs output.
476    o New variable in PARM03 for more flexible pickups
477    o somewhat cleaned package initialisation sequence for
478      ctrl/ cost/ ecco/ in packages_... routines
479    
480    checkpoint50g_post
481    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
482      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
483      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
484        made the default because of faster convergence than ADI
485    
486    checkpoint50f_post
487    o exf totally restructured
488      - replaced all exf_set_ routines by one generic exf_set_gen.F
489        and made sure it's still differentiable
490      - split exf_getffields.F into new exf_bulkformulae.F
491      - exf_inscal_/exf_outscal_ suffixes consistent with field names

496          + change Evap over land. (update aim.5l_cs output)
497     o added missing .cvsignores and made uniform across expts
498     o changed configuration of tidal_basin_2d expt
499     o added pkg/debug functions for tracing code in fatal crashes
500     o tidied pkg/monitor to use MONITOR_OPTIONS.h
501     o new fn in pkg/monitor to stop model if solution grows too big
502     o removed lots of single quotes from comments
503    
504    checkpoint50e_post
505    o make KPP work with PTRACERS
506     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
507       nearly a copy of kpp_transport_s
508     - there is no analogue to SurfaceTendencyS, so I have to use
509       gPtr(of the surface layer) instead
510    o add a new platform SunFire+mpi (SunFire 15000) to genmake
511    checkpoint50e_pre
512    
513    checkpoint50d_post
514    o change kpp output from multiple-record state files to single-record state
515      files analogous to write_state.F
516    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
517      analogous to the cg2d-related output.
518    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
519      so that writing to internal file fn (with length 512) fails.
520    checkpoint50d_pre
521    
522    checkpoint50c_post
523    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
524    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
525    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
526    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
527    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
528    
529    checkpoint50c_pre
530    Merging from release1_p13:
531    o bug fix for pkg/seaice dynamic solver
532    o Added SEAICE_initialHEFF to pkg/seaice
533    
534    checkpoint50b_post
535    o store u*,v* in gU,V instead of in guNm1,gvNm1
536    o in order to put the momForcing out of the Adams-Bashforth:
537      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
538      to timestep.F
539    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
540    o re-generate output for highly sensitive test-exp:
541       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
542    
543    checkpoint50b_pre
544    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
545    o corrected CPP option mismatch in exf_Bulk... functions for case
546      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
547    
548    checkpoint50a_post
549    o Bug fix for merging between c50 and KPP.
550      ikey was passed from thermodynamics to kpp_calc via
551      common block rather than being recomputed in kpp_calc,
552      in contradiction with new key itdkey.
553      New key ikppkey created, and tamc.h headers updated.
554    
555    checkpoint50
556    - 2nd step of merge with ecco-branch:
557      merge changes in ecco-branch back into main trunk
558    - bug fix in find_alpha
559    - more storing in gmredi_calc_tensor.F, kpp_routines.F
560    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
561    - merged some sliced AD support routines
562    
563    checkpoint49
564    merged from ecco-branch:
565    o exf:
566      - Enable initialisation of forcing fields to constant
567        (runtime) values.
568      - in exf_getffields.F
569        Reduce i-/j-loop to interior domain, discarding overlaps.
570        That also fixes wrong TAF-key computations for key_1, key_2
571        with bulf formulae.
572      - exf_init.F modify #ifdef for exf_init_evap
573      - exf_getffieldrec.F, ctrl_getrec.F
574        The following INT-usages are not safe:
575          fldsecs  = int(fldsecs/fldperiod)*fldperiod
576          fldcount = int(fldsecs/fldperiod) + 1
577        and were modified.
578    o autodiff: checkpoint_lev...
579      - updated storing for bulk formulae (some arrays were missing)
580      - added state for seaice package
581      - synchronized with main branch
582    o DIVA:
583      Modif.s in
584      - the_main_loop.F
585      - the_model_main.F
586      and added cost_final_restore.F cost_final_store.F
587      o With these changes, it is possible to fully separate
588        the first forward run to compute the cost function (mdthe_main_loop)
589        and adjoint runs over individual DIVA intervals (adthe_main_loop)
590        into separate model executions.
591        This enables better tuning of DIVA to given queue sizes.
592      o Loss of cost function value in consecutive DIVA runs is
593        fixed by storing to 'costfinal' file.
594      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
595        beginning/end of adjoint integration is accounted for.
596      The current changes apply to TAF-1.4.26.
597      TAF has one remaining bug, requiring one manual change
598      (see MITgcm manual).
599    o cal: synchronized between MAIN and ecco-branch
600    
601    checkpoint48i_post
602    o Changes to restore differentiability of code w.r.t. previous tag
603      (mostly adding new routines to make list and replacing
604      pressure by totPhiHyd).
605    o Updated and merged grdchk package
606      - has both ADM and TLM checks
607      - works for single- and multi-proc.
608      - output cleaned
609      - worked successfully for parallel DIVA
610    o genmake:
611      - Adding -platform=SP4
612      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
613    o Modif. for DIVA:
614      ctrl_unpack should not be called in intermediate DIVA interval.
615      (similar thing would apply for active files such as
616      tbar, sbar, psbar, which should not be reinitialised;
617      only relevant for ecco-branch)
618    
619    checkpoint48h_post
620    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
621    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
622    o Added SEAICE_initialHEFF to pkg/seaice
623    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
624    
625    checkpoint48g_post
626    --- EOS:
627    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
628      store total Potential in totPhyHyd for diagnostics & EOS.
629    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
630    --- Pressure/geopotential gradient:
631    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
632    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
633      ( changes results of global_ocean_pressure )
634    o NLFS + z-coord.: add eta*Rho' contribution.
635    o accurate phiHyd when using interface-W at the middle between 2 centers
636     ( changes results of ideal_2D_oce )
637    o includes r* 2nd term in potential gradient.
638    
639    checkpoint48f_post
640    Merging from release1_p12:
641    o Modifications for using pkg/exf with pkg/seaice
642      - improved description of the various forcing configurations

644      - units/sign fix for evap computation in exf_getffields.F
645      - updated verification/global_with_exf/results/output.txt
646    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
647      (SBO) core products, including oceanic mass, center-of-mass,
648      angular, and bottom pressure (see pkg/sbo/README.sbo).
649    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
650      to avoid negative values in shallow regions.
651      - updated verification/natl_box/results/output.txt
652      - updated verification/lab_sea/results/output.txt
653    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
654    o Added useSingleCpuIO option (see PARAMS.h).
655    o Updated useSingleCpuIO option in mdsio_writefield.F to
656      work with multi-field files, e.g., for single-file pickup.
657    o pkg/seaice:
658      - bug fix in growth.F: QNET for no shortwave case
659      - added HeffFile for specifying initial sea-ice thickness
660      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
661    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
662      kpp_transport_t.F, forward_step.F, and the_main_loop.F
663    o pkg/seaice:
664      - adjoint-friendly modifications
665      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
666    
667    checkpoint48e_post
668    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
669    o dynamics: change definition of computational domain & adapt mom_fluxform
670      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
671    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
672        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
673        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
674        global_ocean.90x40x15 global_with_exf global_ocean_pressure
675        inverted_barometer solid-body.cs-32x32x1
676      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
677    
678    checkpoint48d_post
679    o in preparation for r*:
680     a) use pre-computed gradient of hydrostatic potential:
681        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
682     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
683        => affects results of glob_oce_pressure (different truncation error)  
684      update output.txt of ideal_2D_oce & global_ocean_pressure
685    
686    checkpoint48d_pre
687    o in preparation for r*:
688      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
689      pass the 2 comp. of the grad. as arguments to momentum S/R.
690      but for the moment, only used if it does not change the results.
691    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
692    
693    checkpoint48c_post
694    Modifications in treatment of initial flux forcing controls
695    to avoid extra storing of flux fields.
696    
697    checkpoint48c_pre
698    o Added tidal_basin_2d experiment (currently 1D!)
699    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
700    
701    checkpoint48b_post
702    o r* coordinate added in #ifdef NONLIN_FRSURF block.
703     (modification to pressure gradient not yet implemented)
704    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
705      (for U & V) that are used for vertical advection of momentum.
706    
707    checkpoint48a_post
708    o In preparation for r*, use temp. array to compute vertical transport
709       in flux-form momentum pkg. => change results of few test-exp.
710      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
711                        lab_sea, natl_box & plume_on_slope
712    
713    checkpoint48
714    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
715    
716    checkpoint47j_post
717    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
718    o moved adexch from forward_step to addummy_in_stepping
719    o added exch in ctrl_map_...
720    o aveFreq.=0. at end of cost_final to avoid overwrite in
721      reverse checkpointing loop
722    o Yet more changes in gmredi:
723      * adgmredi_calc_tensor
724        avoiding all recomputation of gmredi_slope_limit
725      * adgmredi_x/y/rtransport
726        added flag for excessive storing to avoid recomp. of
727        u/v/rtans, dTdx/y/z
728        -> this is not really necessary and very memory-consuming
729      * adgmredi_slope_psi:
730        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
731      * gmredi_slope_limit
732        re-activated full calculation of taperfct for case 'ac02'
733    o updating verification/ adjoints of carbon, global_ocean.90x40x15
734    
735    checkpoint47i_post
736    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
737    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
738      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
739    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
740    o gmredi: fix few bugs.
741    
742    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
743    This will be a good checkpoint to plug into the ecco-branch.
744    o few modif.'s to get latest version adjointed
745      (mainly kick out code in ini_linear_phisurf)
746    o modif's to run adjoint with exactConserv
747    o case GM_BOLUS_ADVEC should be cleaned
748      S/R gmredi_slope_psi should be cleaned
749    o verification/carbon now has exactConserv=.TRUE.
750    
751    checkpoint47g_post
752    o time-average AIM output: becomes independent from statvars time-average
753      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
754    o After TAF bug fix:
755      Tested adjoint of gmredi package.
756      Tests were done with checkpoint47 rather than with latest
757      checkpoint47f_post since the latter is broken for the adjoint
758      verification/carbon/ contains both ADM and TLM gradient checks.
759    Here they are, before they get changed/lost/stolen.
760    Mostly modif.'s to fix numerical sensitivities.
761    Gradient checks OK for
762    - GM_taper_scheme:
763      * clipping
764      * ac02
765      * linear
766      * glw91
767      * dm95
768      * ldd97
769    - GMREDI_OPTIONS:
770      * GM_VISBECK_VARIABLE_K
771      * GM_NON_UNITY_DIAGONAL
772      * GM_EXTRA_DIAGONAL
773      * GM_BOLUS_ADVEC
774    in conjunction with data.gmredi parameters to be checked in
775    in a few minutes under verification/carbon/code/
776    
777    checkpoint47f_post
778    Merging from release1_p10:
779    o modifications for using pkg/exf with pkg/seaice
780      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
781        and SEAICE_EXTERNAL_FLUXES
782      - pkg/exf CPP options EXF_READ_EVAP and
783        EXF_NO_BULK_COMPUTATIONS
784      - usage examples are Experiments 8 and 9 in
785        verification/lab_sea/README
786      - verification/lab_sea default experiment now uses
787        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
788    
789    checkpoint47e_post
790    o created a tag prior to creating a branch
791    
792    checkpoint47d_post
793    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
794      at the bottom boundary had an erroneous half slip boundary condition
795    o added bottom drag and no slip boundary condition capabilities to
796      oceanic pressure coordinates code
797    o added new verification experiment global_ocean_pressure, this experiment is
798      also described in the tutorial section of the manual
799    checkpoint47d_pre
800    
801    checkpoint47c_post
802    o Added a verification experiment for a global cubed-sphere ocean run
803      -  verification/global_ocean.cubed32x32x30
804      -  uses pkg/therm_seaice and pkg/bulk_forcing
805    
806    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
807    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
808      when using P-coordinate; only implemented for atmospheric config.
809    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
810      NOTES: requires option NONLIN_FRSURF to be "#define".
811    o update advect_xz/results/output.txt (left from checkpoint44g_post)
812    
813    checkpoint47b_post
814    Merging from release1_p9:
815    o pkg/seaice
816      - removed GOTO's and added taf directives
817      - double precision constants to reduce the g77 (Linux)
818        to F77 (SGI) differences reported in release1_p8
819    o tools/genmake
820      - added SGI options
821    o verification/testscript
822      - updated to that of checkpoint47a_post
823    o verification/global_ocean.90x40x15/input/eedata
824      - modified for SGI f77 compatibility

827      - added missing matlab routines
828      - added test of thermodynamics parallelization
829    
830    checkpoint47a_post
831    o new pkg: aim_v23
832     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
833       for now, keep the same surface forcing as before.
834     - Part-Cell implemented into AIM; check that Heat & Water are conserved
835     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
836     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
837    o add diagnostic of surface correction term in monitor output
838    
839    o bulk_force and therm_seaice
840    - Two packages:  bulk_force (Bulk forcing)
841      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
842    - Earlier integration from Stephaine Dutkiewicz
843      and Patrick Heimbach.
844    - Two ifdef statements for compile time,
845       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
846    
847    checkpoint47
848    differentiable version of checkpoint46n_post
849    o bug fix in quasihydrostaticterms
850    o * "clean" adjoint code (in terms of extensive recomputations)
851        can now be obtained for all GMREDI options (i.e. for
852        - GM_VISBECK_VARIABLE_K
853        - GM_NON_UNITY_DIAGONAL
854        - GM_EXTRA_DIAGONAL
855        - GM_BOLUS_ADVEC )
856      * However, wrong gradient check problem remains unsolved.
857      * New CPP options have been introduced for different
858        tapering schemes
859    o external_fields_load now part of differentiation list
860    o pressure needs multiple storing;
861      would be nice to have store_pressure at beginning or
862      end of forward_step, e.g. by having phiHyd global (5-dim.)
863      (NB: pressure is needed for certain cases in find_rho,
864      which is also invoked through convective_adjustment).
865    o recomputations in find_rho for cases
866     'JMD95'/'UNESCO' or 'MDJWF' are OK.
867    o #define ATMOSPHERIC_LOADING should be differentiable
868    o ini_forcing shifted to begining of initialise_varia
869    o Incorporating QNVS line search routines into MITgcm
870      (this is separate code, and therefore not under pkg)
871      lsopt/, optim/
872    o Updated verification/carbon/
873      - #define GM_VISBECK_VARIABLE_K
874      - GM_taper_scheme    = 'ldd97'    
875    
876    checkpoint46n_post
877    Merging from release1_p8:
878    o verification/natl_box:
879      updating new external_fields_load routine
880    o New package: pkg/seaice
881      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
882      The sea-ice code is based on Hibler (1979-1980).
883      Two sea-ice dynamic solvers, ADI and LSR, are included.
884      In addition to computing prognostic sea-ice variables and diagnosing
885      the forcing/external data fields that drive the ocean model,
886      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
887      The implied surface heat flux is then stored in variable
888      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
889      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
890      non-local transport term.  Because this call precedes model
891      thermodynamics, temperature under sea-ice may not be "exactly" at
892      the freezing point by the time theta is dumped or time-averaged.
893      N.B.: fairly large differences in accuracy occur across
894            different platforms/compilers; comparison between
895            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
896            generated output gives:
897       T           S           U           V

902    
903      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
904    o GAD:
905      - generated new common blocks to account for call of
906        same gad routines with differing traceridentities
907        (needed to modify tracerIdentity indices in GAD.h)
908      - generated separate common blocks for case useCubedSphereExchange
909        (Department of Futurology)
910      - parameter lists to gmredi_?transport: added tracerIdentity
911      - added new key indices to tamc.h
912    o external_fields_load:
913      - added this routine to TAF list
914      - needed to make some common blocks global and additional storing
915        along the same lines as exf package (checkpoint_lev?_directives.h)
916    o exf:
917      updated external forcing package
918      - bug fixes carried over from ecco-branch
919        (missing OBCS_OPTIONS.h in two routines)
920      - enable easy to use "no forcing".
921      - added exf I/O for atmospheric loading
922      - added exf I/O for runoff data
923      - transfered scaling between exf <-> MITgcm to exf namelist
924    o Adding new verification experiment global_with_exf.
925      This verification experiment is almost identical to the
926      global_ocean.90x40x15 experiment, except that it uses
927      the exf (and cal) package instead of the
928      external_fields_load routine (cf README file).
929    
930    checkpoint46m_post
931    o modified testscript to return -- when there are no lines of "%MON" output
932    o added new flag "quasiHydrostatic" for QH mode
933      and new routine quasihydrostaticterms()
934    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
935      New routine: mom_u_coriolis_nh()
936    o fixed sign of non-hydrostatic metric terms in u and v equations.
937      Depend on correct sign of gravitySign.
938    o added work.pc* to .cvsignore in aim directories using ifc
939    o introduced flag for controllin non-hydrostatic metric terms
940    o removed gravitySign from PARM04
941    o switched to g77/ifc from pgf77 in aim experiments
942    
943    checkpoint46l_post
944    o made convective adjustment work with pressure coordinates:
945     - changed the direction of k-loop in convective_adjustment.F for the
946       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
947     - adjusted the reference pressure k-index in convective_adjustment.F
948     - adjusted the convection condition in convect.F (in analogy to
949       calc_ivdc.F)
950     - convective_adjustment no longer computes anything on the halos
951     - removed the warnings about negative salinity from find_rho.F and
952       find_alpha.F; instead the new routine look_for_neg_salinity, called
953       at the beginning of find_rho, find_alpha, and find_beta, does a
954       check of the entire slice, if CPP-option
955       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
956    checkpoint46l_pre
957    
958    checkpoint46k_post
959    o fixed the verification/global_ocean.90x40x15 experiment:
960     - new bathymetry (the world according to A., JMC, and M.)
961     - new initial fields and forcing fields (*.bin files)
962     - new POLY3.COEFFS (for the next release one should switch to a full
963       equation of state: JMD95P or MDJWF)
964     - fixed several errors and redundancies in the data file
965     - experiment uses looped cells
966     - added matlab directory with diagnostic scripts for plotting of output
967    
968    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
969     - read AIM physics parameters from a file (data.aimphys)
970     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
971    
972    checkpoint46j_post
973    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
974    o move wVel computation at the end of the time step, in S/R integr_continuity
975    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
976    o update timeave pkg for wVel diagnostic.
977    checkpoint46j_pre
978    
979    checkpoint46i_post
980    o Clean up AIM package (and keep the results unchanged):
981      include CPP_OPTION and use IMPLICT NONE in all routines ;
982      declare all the variables _RL ; use _d 0 for all numerical constants.
983      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
984    
985    checkpoint46h_post
986    o cleaned up the use of rhoNil and rhoConst.
987      - rhoNil should only appear in the LINEAR equation of state, everywhere
988        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
989        and the dynamical equations are all divided by rhoConst
990    o introduced new parameter rhoConstFresh, a reference density of fresh
991      water, to remove the fresh water flux's dependence on rhoNil. The default
992      value is 999.8 kg/m^3
993    o cleanup up external_forcing.F and external_forcing_surf.F
994      - can now be used by both OCEANIC and OCEANICP
995    checkpoint46h_pre
996    
997     Added code to convert surface volume flux (fresh water) into
998     a mass flux when using P coordinates in the ocean (OCEANICP).
999     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1000    
1001    checkpoint46g_post
1002    o Include a new diagnostic variable phiHydLow for the ocean model
1003      - in z-coordinates, it is the bottom pressure anomaly
1004      - in p-coordinates, it is the sea surface elevation
1005      - in both cases, these variable have global drift, reflecting the mass
1006        drift in z-coordinates and the volume drift in p-coordinates
1007      - included time averaging for phiHydLow, be aware of the drift!
1008    o depth-dependent computation of Bo_surf for pressure coordinates
1009      in the ocean (buoyancyRelation='OCEANICP')
1010      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1011        Theta, Salinity, and Pressure in the parameter list. This routine is
1012        presently contained in find_rho.F. This routine does not give the
1013        correct density for 'POLY3', which would be a z-dependent reference
1014        density.
1015    o cleaned up find_rho
1016      - removed obsolete 'eqn' from the parameter list.
1017    o added two new verification experiments: gop and goz
1018      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1019    checkpoint46g_pre
1020    
1021    checkpoint46f_post
1022    o Enable tangent linear (forward mode) gradient checks:
1023      - extended active file handling to g_... files
1024      - added TANGENT_SIMULATION to theSimulationMode
1025      - extended grdchk package accordingly
1026    o added tangent linear setup in verification/carbon/code_ftl
1027    o added adjoint setup in verification/front_relax/code_ad
1028    
1029    checkpoint46e_post
1030    o Added new equation of state -> MDJWF
1031      - EOS of McDougall et al., 2002, JAOT, submitted
1032      - caveat: the equation of state is only valid for a smaller (more
1033        realistic?) range of values than JMD95P/Z and UNESCO
1034      - added masks to the calculation of pressure in store_pressure
1035      - added more check values for density in check_eos (ini_eos.F), some of
1036        the old check values are out of the range of the MDJWF-eos, so don't
1037        expect perfect matches for those
1038    checkpoint46e_pre
1039    
1040    checkpoint46d_post
1041    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1042      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1043      case of pressure coordinates. eosType='JMD95Z' in
1044      combination with buoyancyRelation='OCEANICP' now causes an error.
1045    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1046      in find_alpha/beta.
1047    checkpoint46d_pre
1048    
1049    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1050      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1051    
1052    checkpoint46c_post
1053    o Changes necessary for ocean in p-coordinates
1054     -  Added new buoyancy relation = 'OCEANICP'
1055     -  Added new parameters = gravitySign (this used to be contained inside
1056        the factor dRdZ which I added when we first switched to R coordinates).
1057     X GM/Redi is not compatible (yet)
1058     X bottom drag and no-slip need to be debugged.
1059    checkpoint46c_pre
1060    
1061    checkpoint46b_post
1062    o Added new equation of state -> JMD95Z and JMD95P
1063      - EOS of Jackett and McDougall, 1995, JAOT
1064      - moved all EOS parameters into EOS.h
1065      - new routines ini_eos.F, store_pressure.F
1066    o Added UNESCO EOS, but not recommended because it requires
1067      in-situ temperature (see JMD95)
1068    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1069      unesco.f to be used with POLY3
1070    checkpoint46b_pre
1071    
1072    checkpoint46a_post
1073    o Added (atmospheric) pressure loading
1074      - new field in FFIELDS.h, etc...
1075      - new cpp flag ATMOSPHERIC_LOADING
1076    o Changed hFacC to _hFacC in calc_phi_hyd.F
1077    o Added SHORTWAVE_HEATING to some files for consistency
1078    checkpoint46a_pre
1079    
1080    checkpoint46
1081    further merges from release1_p5
1082    o new ctrl package
1083      - adopted from ECCO environment to enable optimization
1084      - added Eliassen Palm fluxes to controls
1085    o added Eliassen Palm flux controls to gradient check package
1086    o cost package
1087      - Compatible with new ctrl package
1088      - added Eliassen Palm cost hooks
1089      - modif's of existing cost functions
1090    o Adjoint-related bug fixes in kpp:
1091      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1092      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1093    o autodiff package
1094      - flow directives:
1095        + new for S/R do_the_model_io
1096        + enhanced for S/R checkpoint
1097        + new gmredi.flow
1098      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1099        disable adcommon.h/g_common.h by default.
1100      - fixed problem for adjoint of global_max
1101    o modified verification/carbon/
1102    o New setup for adjoint of global_ocean
1103    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1104    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1105    o incorporated hooks for sponge layer code (external_forcing.F)
1106    
1107    checkpoint45d_post
1108    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1109    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1110      (affects plume_on_slope "cg2d" output)
1111    o add new parameter deltaTfreesurf for free-surface time stepping
1112    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1113    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1114    o change phiMin in exp1 (to agree with documentation)
1115    o add new flags:
1116     - T,S forcing inside/outside Adams-Bashforth
1117     - turn off temp,salt advection and/or forcing
1118     - for each tracer, define internal flag for multiDimAdvection & A-B
1119    o monitor: change definition of KE to check conservation of Energy
1120    
1121    checkpoint45c_post
1122    o Removed f90 comments ("!")
1123    o Modified initialisations to enable exf package for MITgcm
1124      (without invoking ECCO_PACKAGE).
1125    o modifications to gradient check package (Martin Losch)
1126      - enable centered differences
1127      - modified format of standard output
1128    
1129    checkpoint45b_post
1130    o cleaned exchange calls in cg2d
1131    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1132    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1133      to configure barotropic setup (Martin Losch)
1134    o moved some initialisations within bi,bj loop in dynamics
1135      (TAF flow dependency)
1136    o in initialise_varia, moved call packages_init_variables
1137      before convective_adjustment_init
1138      (corresponding adjustment of TAF tape initialisation).
1139    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1140    
1141    checkpoint45a_post
1142    o compute Rho over the whole domain (extend iMin,jMin indices)
1143    o specific exchange for X-slice domain (case Ny=1)
1144    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1145    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1146    
1147    checkpoint44h_post = checkpoint45
1148    o Fix to restore differentiability:
1149      place at which packages_init_variables is called in
1150      initialise_varia is crucial for reverse control flow.
1151    o modifications in GMRedi to enable stable adjoint
1152      (corresponding modif's in thermodynamics, dynamics)
1153    o added missing hook for sponge layer code in external_forcing
1154    o modified test cost functions
1155    o storing in gad_advection (plus removal of write(0,*)!
1156    o missing headers TR1.h added in convective_adjustment routines
1157    o errorMessageUnit set non-equal zero in eeboot
1158      (conflict on some platforms, e.g. IBM SP3)
1159    o modified carbon verif.
1160    
1161    checkpoint44h_pre
1162    o vertical grid option: allow to put the Interface at the middle between
1163      2 cell-centers ; replace delZ in pkg/kpp by drF.
1164    o GM Advective form: Tracers are advected using the residual transport (=
1165      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1166    
1167    checkpoint44g_post
1168    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1169      results) ; ifdef missing in thermodynamics.F
1170    
1171    checkpoint44f_pre,checkpoint44f_post
1172    o added PTRACERS package
1173      This allows an arbitrary number of passive tracers to be integrated
1174      forward simultaneously with the dynamicaly model.
1175      + Implemented so far:
1176        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1177        - I/O and checkpointing
1178        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1179      + Not implemented so far:
1180        - KPP
1181        - OBCS
1182      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1183        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1184        line in data.pkg.
1185      + This package is disabled by default since it increases storage.
1186    
1187    
1188    o testscript: added -cleanup option
1189    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1190                 b) enable to filter 2D fields.
1191    
1192    checkpoint44e_pre,post
1193    o re-wrote convective adjustment to use pre-calculated weights
1194      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1195      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1196      Original calls to convect() still in place.
1197    
1198    chkpt44d_pre,post
1199    o added missing EXCLUDE_MONITOR flags
1200    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1201      (incompatible typ in MIN/MAX expressions caused problems
1202      on IBM SP3)
1203    o in genmake added variable MAKEDEPEND
1204      plus resetting for case SunOS
1205    o added timer_stats.c routine for IBM SP3
1206    o removed variables in dynamics
1207    !!! I forgot to create tag chkpt44d_pre !!!
1208    !!! But chkpt44d_pre = chkpt44c_post    !!!
1209    
1210    o real fresh water flux implemented with non-linear free-surface.
1211    
1212    chkpt44c_pre,post
1213    o few fix (mask in shap_s2, EmPmR in external_field_load,
1214      USE_NATURAL_BCS in solve_for_P);
1215    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1216    
1217    checkpoint44b_pre/_post
1218    o merge of relevant stuff from the ecco-branch:
1219      - genmake: removed $S64 overwrite for case SunOS
1220      - pkg/exf: update and corrections for field swapping and obcs
1221      - pkg/ecco: parameter lists for the_model_main, the_main_loop
1222                  harmonized between ECCO and MITgcm
1223      - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
1224                      updated checkpointing_lev... lists for obcs
1225      - model/src: minor changes in forward_step, plot_field
1226                   added directive for divided adjoint in the_main_loop

1248    o Store directives up-to-date with re-arranged Adams-Bashforth
1249      (mainly thermodynamics.F)
1250    o New store directives for multi-dim. advection schemes
1251      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1252      * new common block and key passkey

1280      
1281    checkpoint40pre8
1282    o new package rw/
1283      Added method for dumping intermediate local arrays:
1284      mdsio_writetile - same as mdsio_writefield except works from inside
1285                        bi,bj loop
1286      mdsio_writelocal - same as mdsio_writetile except works for local
1287                         arrays
1288      write_local_r? - higher-level wrapper for mdsio_writelocal
1289      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1290      Example given at end of mom_vecinv.F that dumps some local arrays.
1291    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1292      control flux-form versus vector invariant code.
1293      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1294      or genmake -DISABLE ...
1295    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1296      (additional storing is now needed for case vecinv;
1297      currently nothing implemented to switch this storing off
1298      in case fluxform is used since no CPP flag available).
1299    
1300    checkpoint40pre7
1301    o bug fix in dynamics.F
1302      calc_viscosity called before k=1,Nr loop.

1312    o Added diffkr, kapgm to control variables
1313    o bug fix in gmredi_slope_limit for ldd97
1314    
1315    checkpoint40pre5
1316    o proper initialization of Adams-Bashforth time stepping
1317      + uses forward step for very first step of model (iter=0)
1318    o re-generated *all* output since almost all output is modified by this
1319      change (sorry but we've been putting this one off for about 2 years)
1320      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1321        *not* regenerated since they are already out of date and I don't
1322        want to create the impression that they are suddenly working.
1323    o removed KAP stuff for DEC's
1324    o modified/added many .cvsignore files in */code and */input
1325    o added new expt "solid-body.cs-32x32x1"
1326      + this uses an alternative form of ini_curvilinear_grid.F which
1327        is not necessarily any better than the current one...
1328    
1329    checkpoint40pre4
1330    o added re-initialisations of utrans,vtrans,rtrans in
1331      calc_common_factors which are crucial for TAF.
1332    o extended iMin,jMin range for calc_common_factors,
1333      calc_diffusivity

1341    
1342    checkpoint40pre2
1343    o Updated to latest branch of AJA, JMC
1344    o Added gradient check package

1346    o Added carbon sequestration sensitivity experiment
1347    
1348    checkpoint39
1349     o Modifications and fixes to support TAMC
1350       (mainly missing or wrong directives)
1351     o Corrected common blocks when fooling TAMC to produce adjoint I/O
1352       in addummy_in_stepping
1353     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1354     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1355     o Included following packages:
1356       cal: calendar
1357       exf: external forcing
1358       ecco: essential routines to control use of cal, exf
1359             (NB: this is not the full ECCO environment)
1360     o disabled some packages by default in genmake
1361    
1362    checkpoint38
1363     o see notes_c37_adj.txt
1364     o corrected wrong layer index in external_forcing_t
1365     o replaced the_main_loop/forward_step by the_main_loop
1366     o removed forceoutput from write_state
1367       (replaced criteria for initial/final state)
1368     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1369    
1370    checkpoint37
1371     o mdsio.F routine split and packaged in pkg/mdsio
1372       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1373        used unless genmake -disable=mdsio)
1374     o allow a more precise surface-geopotential gradient for the atmosphere
1375       taking into account the change in space of Alpha (=1/rho) at the surface.
1376     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1377       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1378     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1379       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1380       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1381     o Time-Average diagnostics defined as a pseudo package "timeave".
1382     o pickup files : old pickup (before c35) did not work with new code (c35
1383       and after) unless activating 2 commented lines in initialise-varia.
1384     o Non-Hydrostatic pickup file Pb fixed.
1385     o bug with Rigid-lid version (since c35) fixed.  
1386    
1387  checkpoint36  checkpoint36
1388   o implement Crank-Nirotropic time-stepping   o implement Crank-Nickelson barotropic time-stepping
