4      ==============================      ==============================
5    
6    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
7      mon_vort3.F to make exch2 friendly with >1 tile per cube
8      face
9

11    o removed CPP_EEOPTIONS.h from verification/*/code
12    o updated the tiling for global_ocean_pressure
13    checkpoint52i_pre
14    
15    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
16      the old pkg/aim).
17    
18    checkpoint52h_pre
19    o shortened offending lines in exch2_send_rx?.template
20    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator

23      old grid files, moved CPP_EEMACROS.h to pkg/exch2
24    o added useSingleCPUIO flag to monitor.F and mon_out.F
25    o added temporary hack for sea-ice dynamics on the cube:
26      metric terms are ignored and it is assumed that
27      there is no sea-ice on cube faces 1, 2, 4, and 5.
28    
29    checkpoint52f_post
30    o added exch2 cube routines to pkg/exch2
31    o modified hs94.cs-32x32x5 to use it
32    o added new grid files to hs94.cs-32x32x5
33    checkpoint52f_pre
34    
35    checkpoint52e_post
36    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
37      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
38    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
39      to work with implicit vertical advection and AB ;
40    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
41    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
42     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
43    checkpoint52e_pre
44

48    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
49      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
50    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
51    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
52    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
53    
54    checkpoint52d_post
55    o re-tiled many expts to allow comparison in multi-processor mode
56      - updated output accordingly
57      - changed hs94.128x64x5 to use intial T from file rather than use the
58        random number generator
59    o add infrastructure in model routines for fizhi and gridalt packages
60    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
61    o changes to permit hi-res, cubed-sphere, configuration
62      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
63      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
64      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
65        of surface winds for the cube
66      (A verification experiment, based on global_ocean.cs32x15, but with
67       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
68       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
69       complete with example surface forcing files and matlab scripts to look
70       at the output and compare it with that of global_ocean.cs32x15.)
71    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
72       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
73       to conform to the common rule.
74    o check-in the first version of the coupler + interfaces for multi-components
75       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
76       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
77       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
78       - ocean and atmos. share the same horizontal grid (no interpolation).
79       - exchanges between component and coupler is done in forward_step
80    o new verification experiment, cpl_aim+ocn:
81       coupled ocean - AIM atmosphere on cs32 grid.
82    
83    checkpoint52d_pre
84    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
85    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
86    
87    checkpoint52c_post
88    o Fixing OPTIONS files for use of exf:
89      - ALLOW_ECCO not needed
90      - ECCO_CPPOPTIONS.h should not be included from
91        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
92        as has been the case in the past
93      - All cal/exf related options are currently set in
94        single header file. Should remain so until we
95        agree on a consistent new policy.
96    o Removed all CPP options for cal package.
97      cal has no more CPP options.
98    o modified STOREs in GAD_ADVECTION
99    o corrected key comp. for passkey
100    
101    checkpoint52b_post
102    o new version: "thsice" of thermodynamic sea-ice pkg:
103     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
104     - modify fluxes but do not change theta directly;
105     - light cleaning of bulk_force pkg (still needed with thsice).
106     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
107       + output_thsice.txt to test thsice & bulk_force pkgs.
108    o put back grid & coriolis monitor output.
109    checkpoint52b_pre
110    
111    o call "do_the_model_io" at the beginning (=> dump initial state)
112    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
113    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
114      (need info on NUMBER_OF_PTRACERS)
115    o missing PTRACERS headers in some routines
116    o default tamc.h in pkg/autodiff supposed to crash
117      to ensure proper customization
118    
119    checkpoint52a_post
120    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
121      - moved surfaceTendencyTice from pkg/seaice to main code
122      - subroutine FREEZE_SURFACE now limits only surface temperature
123        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
124        => new output.txt for global_ocean.cs32x15 & global_with_exf
125      - keep the old version of FREEZE for backward compatibility;
126        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
127      - corresponding modifs for TAF directives
128    o added surface flux output variables to TIMEAVE_STATVARS

135    o some bug fixes for #undef REAL4_IS_SLOW
136    
137    checkpoint52 = ecco_c52_e35
138    o after testing adjoints of checkpoint51u_post
139    
140    checkpoint51u_post
141    o this is the post-merge tag of the ecco-branch
142      (needs another clean checkout and re-testing)
143    o various natl_box_adjoint configs and results
144      but no input fields
145    o obcs adjoint not yet merged!
146    o adding ECCO global 1x1 and 2x2 degree configs
147    o updated/extended some store directives for seaice
148    o pkg/ecco now containes ecco-specific part of cost function
149    o top level routines the_main_loop, forward_step
150      supersede those in model/src/
151      previous input data.cost now in data.ecco
152      (new namelist ecco_cost_nml)
153    o in ctrl/ cleaned some cross-dependencies and updated CPP options
154    
155    checkpoint51t_post
156    o this is the pre-merge tag of the ecco-branch
157    
158    checkpoint51s_post
159    o cleanup: removed various obsolete #define-s
160    o pkg/grdchk
161      - renamed 'ph-grd 3' to 'grad-res'
162      - merged from ecco-branch
163        (remaining bug fixes for obcs gradient checks)
164      - additional high-precision output for testreport
165        (grep for 'precision_grdchk_result')
166    
167    checkpoint51r_post
168    o cleaned up or removed CPP_OPTIONS.h files
169    o updated results for some of the tests to reflect the new
170      optfiles (-ieee: -O0 instead of -O3)
171    
172    checkpoint51q_post
173    o cd_code:
174      - moved cd_scheme.F -> cd_code_scheme.F
175      - separate read_checkpoint from cd_code_ini_vars.F
176      - separated cd_code part from write_checkpoint
177      - updated AD_SOURCE, generated .flow

179      - Moving cd_code specific store dir.s to pkg/cd_code
180    o ctrl package totally restructured
181      - pack/unpack now optional and decoupled from
182        xx_/adxx_ I/O

185      - confined inclusion of AD_CONFIG.h to where necessary.
186    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
187    
188    checkpoint51p_post
189    o create initial cd_code package
190      - WARNING: the initialization of fields within packages
191        is broken because INI_FIELDS (where READ_CHECKPOINT is
192        called) is called *before* PACKAGES_INIT_VARIABLES.
193        This seems to be backwards since
194        1) its important to initially zero the entire field including
195           the "halo" region
196        2) zeroing needs to be done *before* reading pickup info
197           and the pickup call might or might not happen in any
198           particular run
199      - this needs an overhaul for R2
200    o cleanup verification/*/code/GMREDI_OPTIONS.h
201    o cleanup testreport

213      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
214        change rho -> rho-rhoConst
215      - replace call find_rho to find_rhonum

238         global_ocean.cs32x15, and global_with_exf)
239    o added surface flux output variables to TIMEAVE_STATVARS
240    
241    checkpoint51n_pre
242    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

421    
422    checkpoint50f_post
423    o exf totally restructured
424      - replaced all exf_set_ routines by one generic exf_set_gen.F
425        and made sure it's still differentiable
426      - split exf_getffields.F into new exf_bulkformulae.F
427      - exf_inscal_/exf_outscal_ suffixes consistent with field names
428      - updated adjoint/makefile and relevant verif. accordingly
429    
430    checkpoint50f_pre
431     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
432          + change Evap over land. (update aim.5l_cs output)
433     o added missing .cvsignores and made uniform across expts
434     o changed configuration of tidal_basin_2d expt
435     o added pkg/debug functions for tracing code in fatal crashes
436     o tidied pkg/monitor to use MONITOR_OPTIONS.h
437     o new fn in pkg/monitor to stop model if solution grows too big
438     o removed lots of single quotes from comments
439    
440    checkpoint50e_post
441    o make KPP work with PTRACERS
442     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
443       nearly a copy of kpp_transport_s
444     - there is no analogue to SurfaceTendencyS, so I have to use
445       gPtr(of the surface layer) instead
446    o add a new platform SunFire+mpi (SunFire 15000) to genmake
447    checkpoint50e_pre
448    
449    checkpoint50d_post
450    o change kpp output from multiple-record state files to single-record state
451      files analogous to write_state.F
452    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
453      analogous to the cg2d-related output.
454    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
455      so that writing to internal file fn (with length 512) fails.
456    checkpoint50d_pre
457    
458    checkpoint50c_post
459    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
460    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
461    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
462    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
463    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
464    
465    checkpoint50c_pre
466    Merging from release1_p13:
467    o bug fix for pkg/seaice dynamic solver
468    o Added SEAICE_initialHEFF to pkg/seaice
469    
470    checkpoint50b_post
471    o store u*,v* in gU,V instead of in guNm1,gvNm1
472    o in order to put the momForcing out of the Adams-Bashforth:
473      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
474      to timestep.F
475    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
476    o re-generate output for highly sensitive test-exp:
477       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
478    
479    checkpoint50b_pre
480    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
481    o corrected CPP option mismatch in exf_Bulk... functions for case
482      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
483    
484    checkpoint50a_post
485    o Bug fix for merging between c50 and KPP.
486      ikey was passed from thermodynamics to kpp_calc via
487      common block rather than being recomputed in kpp_calc,
488      in contradiction with new key itdkey.
489      New key ikppkey created, and tamc.h headers updated.
490    
491    checkpoint50
492    - 2nd step of merge with ecco-branch:
493      merge changes in ecco-branch back into main trunk
494    - bug fix in find_alpha
495    - more storing in gmredi_calc_tensor.F, kpp_routines.F
496    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
497    - merged some sliced AD support routines
498    
499    checkpoint49
500    merged from ecco-branch:
501    o exf:
502      - Enable initialisation of forcing fields to constant
503        (runtime) values.
504      - in exf_getffields.F
505        Reduce i-/j-loop to interior domain, discarding overlaps.
506        That also fixes wrong TAF-key computations for key_1, key_2
507        with bulf formulae.
508      - exf_init.F modify #ifdef for exf_init_evap
509      - exf_getffieldrec.F, ctrl_getrec.F
510        The following INT-usages are not safe:
511          fldsecs  = int(fldsecs/fldperiod)*fldperiod
512          fldcount = int(fldsecs/fldperiod) + 1
513        and were modified.
514    o autodiff: checkpoint_lev...
515      - updated storing for bulk formulae (some arrays were missing)
516      - added state for seaice package
517      - synchronized with main branch
518    o DIVA:
519      Modif.s in
520      - the_main_loop.F
521      - the_model_main.F
522      and added cost_final_restore.F cost_final_store.F
523      o With these changes, it is possible to fully separate
524        the first forward run to compute the cost function (mdthe_main_loop)
525        and adjoint runs over individual DIVA intervals (adthe_main_loop)
526        into separate model executions.
527        This enables better tuning of DIVA to given queue sizes.
528      o Loss of cost function value in consecutive DIVA runs is
529        fixed by storing to 'costfinal' file.
530      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
531        beginning/end of adjoint integration is accounted for.
532      The current changes apply to TAF-1.4.26.
533      TAF has one remaining bug, requiring one manual change
534      (see MITgcm manual).
535    o cal: synchronized between MAIN and ecco-branch
536    
537    checkpoint48i_post
538    o Changes to restore differentiability of code w.r.t. previous tag
539      (mostly adding new routines to make list and replacing
540      pressure by totPhiHyd).
541    o Updated and merged grdchk package
542      - has both ADM and TLM checks
543      - works for single- and multi-proc.
544      - output cleaned
545      - worked successfully for parallel DIVA
546    o genmake:
547      - Adding -platform=SP4
548      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
549    o Modif. for DIVA:
550      ctrl_unpack should not be called in intermediate DIVA interval.
551      (similar thing would apply for active files such as
552      tbar, sbar, psbar, which should not be reinitialised;
553      only relevant for ecco-branch)
554    
555    checkpoint48h_post
556    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
557    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
558    o Added SEAICE_initialHEFF to pkg/seaice
559    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
560    
561    checkpoint48g_post
562    --- EOS:
563    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
564      store total Potential in totPhyHyd for diagnostics & EOS.
565    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
566    --- Pressure/geopotential gradient:
567    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
568    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
569      ( changes results of global_ocean_pressure )
570    o NLFS + z-coord.: add eta*Rho' contribution.
571    o accurate phiHyd when using interface-W at the middle between 2 centers
572     ( changes results of ideal_2D_oce )
573    o includes r* 2nd term in potential gradient.
574    
575    checkpoint48f_post
576    Merging from release1_p12:
577    o Modifications for using pkg/exf with pkg/seaice
578      - improved description of the various forcing configurations
579      - added basic radiation bulk formulae to pkg/exf
580      - units/sign fix for evap computation in exf_getffields.F
581      - updated verification/global_with_exf/results/output.txt
582    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
583      (SBO) core products, including oceanic mass, center-of-mass,
584      angular, and bottom pressure (see pkg/sbo/README.sbo).
585    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
586      to avoid negative values in shallow regions.
587      - updated verification/natl_box/results/output.txt
588      - updated verification/lab_sea/results/output.txt
589    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
590    o Added useSingleCpuIO option (see PARAMS.h).
591    o Updated useSingleCpuIO option in mdsio_writefield.F to
592      work with multi-field files, e.g., for single-file pickup.
593    o pkg/seaice:
594      - bug fix in growth.F: QNET for no shortwave case
595      - added HeffFile for specifying initial sea-ice thickness
596      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
597    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
598      kpp_transport_t.F, forward_step.F, and the_main_loop.F
599    o pkg/seaice:
600      - adjoint-friendly modifications
601      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
602    
603    checkpoint48e_post
604    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
605    o dynamics: change definition of computational domain & adapt mom_fluxform
606      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
607    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
608        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
609        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
610        global_ocean.90x40x15 global_with_exf global_ocean_pressure
611        inverted_barometer solid-body.cs-32x32x1
612      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
613    
614    checkpoint48d_post
615    o in preparation for r*:
616     a) use pre-computed gradient of hydrostatic potential:
617        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
618     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
619        => affects results of glob_oce_pressure (different truncation error)  
620      update output.txt of ideal_2D_oce & global_ocean_pressure
621    
622    checkpoint48d_pre
623    o in preparation for r*:
624      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
625      pass the 2 comp. of the grad. as arguments to momentum S/R.
626      but for the moment, only used if it does not change the results.
627    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
628    
629    checkpoint48c_post
630    Modifications in treatment of initial flux forcing controls
631    to avoid extra storing of flux fields.
632    
633    checkpoint48c_pre
634    o Added tidal_basin_2d experiment (currently 1D!)
635    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
636    
637    checkpoint48b_post
638    o r* coordinate added in #ifdef NONLIN_FRSURF block.
639     (modification to pressure gradient not yet implemented)
640    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
641      (for U & V) that are used for vertical advection of momentum.
642    
643    checkpoint48a_post
644    o In preparation for r*, use temp. array to compute vertical transport
645       in flux-form momentum pkg. => change results of few test-exp.
646      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
647                        lab_sea, natl_box & plume_on_slope
648    
649    checkpoint48
650    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
651    
652    checkpoint47j_post
653    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
654    o moved adexch from forward_step to addummy_in_stepping
655    o added exch in ctrl_map_...
656    o aveFreq.=0. at end of cost_final to avoid overwrite in
657      reverse checkpointing loop
658    o Yet more changes in gmredi:
659      * adgmredi_calc_tensor
660        avoiding all recomputation of gmredi_slope_limit
661      * adgmredi_x/y/rtransport
662        added flag for excessive storing to avoid recomp. of
663        u/v/rtans, dTdx/y/z
664        -> this is not really necessary and very memory-consuming
665      * adgmredi_slope_psi:
666        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
667      * gmredi_slope_limit
668        re-activated full calculation of taperfct for case 'ac02'
669    o updating verification/ adjoints of carbon, global_ocean.90x40x15
670    
671    checkpoint47i_post
672    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
673    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
674      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
675    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
676    o gmredi: fix few bugs.
677    
678    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
679    This will be a good checkpoint to plug into the ecco-branch.
680    o few modif.'s to get latest version adjointed
681      (mainly kick out code in ini_linear_phisurf)
682    o modif's to run adjoint with exactConserv
683    o case GM_BOLUS_ADVEC should be cleaned
684      S/R gmredi_slope_psi should be cleaned
685    o verification/carbon now has exactConserv=.TRUE.
686    
687    checkpoint47g_post
688    o time-average AIM output: becomes independent from statvars time-average
689      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
690    o After TAF bug fix:
691      Tested adjoint of gmredi package.
692      Tests were done with checkpoint47 rather than with latest
693      checkpoint47f_post since the latter is broken for the adjoint
694      verification/carbon/ contains both ADM and TLM gradient checks.
695    Here they are, before they get changed/lost/stolen.
696    Mostly modif.'s to fix numerical sensitivities.
697    Gradient checks OK for
698    - GM_taper_scheme:
699      * clipping
700      * ac02
701      * linear
702      * glw91
703      * dm95
704      * ldd97
705    - GMREDI_OPTIONS:
706      * GM_VISBECK_VARIABLE_K
707      * GM_NON_UNITY_DIAGONAL
708      * GM_EXTRA_DIAGONAL
709      * GM_BOLUS_ADVEC
710    in conjunction with data.gmredi parameters to be checked in
711    in a few minutes under verification/carbon/code/
712    
713    checkpoint47f_post
714    Merging from release1_p10:
715    o modifications for using pkg/exf with pkg/seaice
716      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
717        and SEAICE_EXTERNAL_FLUXES
718      - pkg/exf CPP options EXF_READ_EVAP and
719        EXF_NO_BULK_COMPUTATIONS
720      - usage examples are Experiments 8 and 9 in
721        verification/lab_sea/README
722      - verification/lab_sea default experiment now uses
723        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
724    
725    checkpoint47e_post
726    o created a tag prior to creating a branch
727    
728    checkpoint47d_post
729    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
730      at the bottom boundary had an erroneous half slip boundary condition
731    o added bottom drag and no slip boundary condition capabilities to
732      oceanic pressure coordinates code
733    o added new verification experiment global_ocean_pressure, this experiment is
734      also described in the tutorial section of the manual
735    checkpoint47d_pre
736    
737    checkpoint47c_post
738    o Added a verification experiment for a global cubed-sphere ocean run
739      -  verification/global_ocean.cubed32x32x30
740      -  uses pkg/therm_seaice and pkg/bulk_forcing
741    
742    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
743    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
744      when using P-coordinate; only implemented for atmospheric config.
745    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
746      NOTES: requires option NONLIN_FRSURF to be "#define".
747    o update advect_xz/results/output.txt (left from checkpoint44g_post)
748    
749    checkpoint47b_post
750    Merging from release1_p9:
751    o pkg/seaice
752      - removed GOTO's and added taf directives
753      - double precision constants to reduce the g77 (Linux)
754        to F77 (SGI) differences reported in release1_p8
755    o tools/genmake
756      - added SGI options
757    o verification/testscript
758      - updated to that of checkpoint47a_post
759    o verification/global_ocean.90x40x15/input/eedata
760      - modified for SGI f77 compatibility
761    o verification/lab_sea
762      - added description of sea-ice model
763      - added missing matlab routines
764      - added test of thermodynamics parallelization
765    
766    checkpoint47a_post
767    o new pkg: aim_v23
768     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
769       for now, keep the same surface forcing as before.
770     - Part-Cell implemented into AIM; check that Heat & Water are conserved
771     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
772     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
773    o add diagnostic of surface correction term in monitor output
774    
775    o bulk_force and therm_seaice
776    - Two packages:  bulk_force (Bulk forcing)
777      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
778    - Earlier integration from Stephaine Dutkiewicz
779      and Patrick Heimbach.
780    - Two ifdef statements for compile time,
781       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
782    
783    checkpoint47
784    differentiable version of checkpoint46n_post
785    o bug fix in quasihydrostaticterms
786    o * "clean" adjoint code (in terms of extensive recomputations)
787        can now be obtained for all GMREDI options (i.e. for
788        - GM_VISBECK_VARIABLE_K
789        - GM_NON_UNITY_DIAGONAL
790        - GM_EXTRA_DIAGONAL
791        - GM_BOLUS_ADVEC )
792      * However, wrong gradient check problem remains unsolved.
793      * New CPP options have been introduced for different
794        tapering schemes
795    o external_fields_load now part of differentiation list
796    o pressure needs multiple storing;
797      would be nice to have store_pressure at beginning or
798      end of forward_step, e.g. by having phiHyd global (5-dim.)
799      (NB: pressure is needed for certain cases in find_rho,
800      which is also invoked through convective_adjustment).
801    o recomputations in find_rho for cases
802     'JMD95'/'UNESCO' or 'MDJWF' are OK.
803    o #define ATMOSPHERIC_LOADING should be differentiable
804    o ini_forcing shifted to begining of initialise_varia
805    o Incorporating QNVS line search routines into MITgcm
806      (this is separate code, and therefore not under pkg)
807      lsopt/, optim/
808    o Updated verification/carbon/
809      - #define GM_VISBECK_VARIABLE_K
810      - GM_taper_scheme    = 'ldd97'    
811    
812    checkpoint46n_post
813    Merging from release1_p8:
814    o verification/natl_box:
815      updating new external_fields_load routine
816    o New package: pkg/seaice
817      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
818      The sea-ice code is based on Hibler (1979-1980).
819      Two sea-ice dynamic solvers, ADI and LSR, are included.
820      In addition to computing prognostic sea-ice variables and diagnosing
821      the forcing/external data fields that drive the ocean model,
822      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
823      The implied surface heat flux is then stored in variable
824      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
825      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
826      non-local transport term.  Because this call precedes model
827      thermodynamics, temperature under sea-ice may not be "exactly" at
828      the freezing point by the time theta is dumped or time-averaged.
829      N.B.: fairly large differences in accuracy occur across

840    o GAD:
841      - generated new common blocks to account for call of
842        same gad routines with differing traceridentities
843        (needed to modify tracerIdentity indices in GAD.h)
844      - generated separate common blocks for case useCubedSphereExchange
845        (Department of Futurology)
846      - parameter lists to gmredi_?transport: added tracerIdentity
847      - added new key indices to tamc.h
848    o external_fields_load:
849      - added this routine to TAF list
850      - needed to make some common blocks global and additional storing
851        along the same lines as exf package (checkpoint_lev?_directives.h)
852    o exf:
853      updated external forcing package
854      - bug fixes carried over from ecco-branch
855        (missing OBCS_OPTIONS.h in two routines)
856      - enable easy to use "no forcing".
857      - added exf I/O for atmospheric loading
858      - added exf I/O for runoff data
859      - transfered scaling between exf <-> MITgcm to exf namelist
860    o Adding new verification experiment global_with_exf.
861      This verification experiment is almost identical to the
862      global_ocean.90x40x15 experiment, except that it uses
863      the exf (and cal) package instead of the
864      external_fields_load routine (cf README file).
865    
866    checkpoint46m_post
867    o modified testscript to return -- when there are no lines of "%MON" output
868    o added new flag "quasiHydrostatic" for QH mode
869      and new routine quasihydrostaticterms()
870    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
871      New routine: mom_u_coriolis_nh()
872    o fixed sign of non-hydrostatic metric terms in u and v equations.
873      Depend on correct sign of gravitySign.
874    o added work.pc* to .cvsignore in aim directories using ifc
875    o introduced flag for controllin non-hydrostatic metric terms
876    o removed gravitySign from PARM04
877    o switched to g77/ifc from pgf77 in aim experiments
878    
879    checkpoint46l_post
880    o made convective adjustment work with pressure coordinates:
881     - changed the direction of k-loop in convective_adjustment.F for the
882       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
883     - adjusted the reference pressure k-index in convective_adjustment.F
884     - adjusted the convection condition in convect.F (in analogy to
885       calc_ivdc.F)
886     - convective_adjustment no longer computes anything on the halos
887     - removed the warnings about negative salinity from find_rho.F and
888       find_alpha.F; instead the new routine look_for_neg_salinity, called
889       at the beginning of find_rho, find_alpha, and find_beta, does a
890       check of the entire slice, if CPP-option
891       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
892    checkpoint46l_pre
893    
894    checkpoint46k_post
895    o fixed the verification/global_ocean.90x40x15 experiment:
896     - new bathymetry (the world according to A., JMC, and M.)
897     - new initial fields and forcing fields (*.bin files)
898     - new POLY3.COEFFS (for the next release one should switch to a full
899       equation of state: JMD95P or MDJWF)
900     - fixed several errors and redundancies in the data file
901     - experiment uses looped cells
902     - added matlab directory with diagnostic scripts for plotting of output
903    
904    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
905     - read AIM physics parameters from a file (data.aimphys)
906     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
907    
908    checkpoint46j_post
909    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
910    o move wVel computation at the end of the time step, in S/R integr_continuity
911    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
912    o update timeave pkg for wVel diagnostic.
913    checkpoint46j_pre
914    
915    checkpoint46i_post
916    o Clean up AIM package (and keep the results unchanged):
917      include CPP_OPTION and use IMPLICT NONE in all routines ;
918      declare all the variables _RL ; use _d 0 for all numerical constants.
919      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
920    
921    checkpoint46h_post
922    o cleaned up the use of rhoNil and rhoConst.
923      - rhoNil should only appear in the LINEAR equation of state, everywhere
924        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
925        and the dynamical equations are all divided by rhoConst
926    o introduced new parameter rhoConstFresh, a reference density of fresh
927      water, to remove the fresh water flux's dependence on rhoNil. The default
928      value is 999.8 kg/m^3
929    o cleanup up external_forcing.F and external_forcing_surf.F
930      - can now be used by both OCEANIC and OCEANICP
931    checkpoint46h_pre
932    
933     Added code to convert surface volume flux (fresh water) into
934     a mass flux when using P coordinates in the ocean (OCEANICP).
935     Note: It assumes you have set rho0=rhoConst=density of fresh water.
936    
937    checkpoint46g_post
938    o Include a new diagnostic variable phiHydLow for the ocean model
939      - in z-coordinates, it is the bottom pressure anomaly
940      - in p-coordinates, it is the sea surface elevation
941      - in both cases, these variable have global drift, reflecting the mass
942        drift in z-coordinates and the volume drift in p-coordinates
943      - included time averaging for phiHydLow, be aware of the drift!
944    o depth-dependent computation of Bo_surf for pressure coordinates
945      in the ocean (buoyancyRelation='OCEANICP')
946      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
947        Theta, Salinity, and Pressure in the parameter list. This routine is
948        presently contained in find_rho.F. This routine does not give the
949        correct density for 'POLY3', which would be a z-dependent reference
950        density.
951    o cleaned up find_rho
952      - removed obsolete 'eqn' from the parameter list.
953    o added two new verification experiments: gop and goz
954      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
955    checkpoint46g_pre
956    
957    checkpoint46f_post
958    o Enable tangent linear (forward mode) gradient checks:
959      - extended active file handling to g_... files
960      - added TANGENT_SIMULATION to theSimulationMode
961      - extended grdchk package accordingly
962    o added tangent linear setup in verification/carbon/code_ftl
963    o added adjoint setup in verification/front_relax/code_ad
964    
965    checkpoint46e_post
966    o Added new equation of state -> MDJWF
967      - EOS of McDougall et al., 2002, JAOT, submitted
968      - caveat: the equation of state is only valid for a smaller (more
969        realistic?) range of values than JMD95P/Z and UNESCO
970      - added masks to the calculation of pressure in store_pressure
971      - added more check values for density in check_eos (ini_eos.F), some of
972        the old check values are out of the range of the MDJWF-eos, so don't
973        expect perfect matches for those
974    checkpoint46e_pre
975    
976    checkpoint46d_post
977    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
978      'OCEANICP', also initialised field pressure correctly in ini_eos in the
979      case of pressure coordinates. eosType='JMD95Z' in
980      combination with buoyancyRelation='OCEANICP' now causes an error.
981    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
982      in find_alpha/beta.
983    checkpoint46d_pre
984    
985    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
986      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
987    
988    checkpoint46c_post
989    o Changes necessary for ocean in p-coordinates
990     -  Added new buoyancy relation = 'OCEANICP'
991     -  Added new parameters = gravitySign (this used to be contained inside
992        the factor dRdZ which I added when we first switched to R coordinates).
993     X GM/Redi is not compatible (yet)
994     X bottom drag and no-slip need to be debugged.
995    checkpoint46c_pre
996    
997    checkpoint46b_post
998    o Added new equation of state -> JMD95Z and JMD95P
999      - EOS of Jackett and McDougall, 1995, JAOT
1000      - moved all EOS parameters into EOS.h
1001      - new routines ini_eos.F, store_pressure.F
1002    o Added UNESCO EOS, but not recommended because it requires
1003      in-situ temperature (see JMD95)
1004    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1005      unesco.f to be used with POLY3
1006    checkpoint46b_pre
1007    
1008    checkpoint46a_post
1009    o Added (atmospheric) pressure loading
1010      - new field in FFIELDS.h, etc...
1011      - new cpp flag ATMOSPHERIC_LOADING
1012    o Changed hFacC to _hFacC in calc_phi_hyd.F
1013    o Added SHORTWAVE_HEATING to some files for consistency
1014    checkpoint46a_pre
1015    
1016    checkpoint46
1017    further merges from release1_p5
1018    o new ctrl package
1019      - adopted from ECCO environment to enable optimization
1020      - added Eliassen Palm fluxes to controls
1021    o added Eliassen Palm flux controls to gradient check package
1022    o cost package
1023      - Compatible with new ctrl package
1024      - added Eliassen Palm cost hooks
1025      - modif's of existing cost functions
1026    o Adjoint-related bug fixes in kpp:
1027      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1028      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1029    o autodiff package
1030      - flow directives:
1031        + new for S/R do_the_model_io
1032        + enhanced for S/R checkpoint
1033        + new gmredi.flow
1034      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1035        disable adcommon.h/g_common.h by default.
1036      - fixed problem for adjoint of global_max
1037    o modified verification/carbon/
1038    o New setup for adjoint of global_ocean
1039    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1040    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1041    o incorporated hooks for sponge layer code (external_forcing.F)
1042    
1043    checkpoint45d_post
1044    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1045    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1046      (affects plume_on_slope "cg2d" output)
1047    o add new parameter deltaTfreesurf for free-surface time stepping
1048    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1049    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1050    o change phiMin in exp1 (to agree with documentation)
1051    o add new flags:
1052     - T,S forcing inside/outside Adams-Bashforth
1053     - turn off temp,salt advection and/or forcing
1054     - for each tracer, define internal flag for multiDimAdvection & A-B
1055    o monitor: change definition of KE to check conservation of Energy
1056    
1057    checkpoint45c_post
1058    o Removed f90 comments ("!")
1059    o Modified initialisations to enable exf package for MITgcm
1060      (without invoking ECCO_PACKAGE).
1061    o modifications to gradient check package (Martin Losch)
1062      - enable centered differences
1063      - modified format of standard output
1064    
1065    checkpoint45b_post
1066    o cleaned exchange calls in cg2d
1067    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1068    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1069      to configure barotropic setup (Martin Losch)
1070    o moved some initialisations within bi,bj loop in dynamics
1071      (TAF flow dependency)
1072    o in initialise_varia, moved call packages_init_variables
1073      before convective_adjustment_init
1074      (corresponding adjustment of TAF tape initialisation).
1075    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1076    
1077    checkpoint45a_post
1078    o compute Rho over the whole domain (extend iMin,jMin indices)
1079    o specific exchange for X-slice domain (case Ny=1)
1080    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1081    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1082    
1083    checkpoint44h_post = checkpoint45
1084    o Fix to restore differentiability:
1085      place at which packages_init_variables is called in
1086      initialise_varia is crucial for reverse control flow.
1087    o modifications in GMRedi to enable stable adjoint
1088      (corresponding modif's in thermodynamics, dynamics)
1089    o added missing hook for sponge layer code in external_forcing
1090    o modified test cost functions

1094      (conflict on some platforms, e.g. IBM SP3)
1095    o modified carbon verif.
1096    
1097    checkpoint44h_pre
1098    o vertical grid option: allow to put the Interface at the middle between
1099      2 cell-centers ; replace delZ in pkg/kpp by drF.
1100    o GM Advective form: Tracers are advected using the residual transport (=
1101      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1102    
1103    checkpoint44g_post
1104    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1105      results) ; ifdef missing in thermodynamics.F
1106    
1107    checkpoint44f_pre,checkpoint44f_post
1108    o added PTRACERS package
1109      This allows an arbitrary number of passive tracers to be integrated
1110      forward simultaneously with the dynamicaly model.
1111      + Implemented so far:
1112        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1113        - I/O and checkpointing
1114        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1115      + Not implemented so far:
1116        - KPP
1117        - OBCS
1118      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1119        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1120        line in data.pkg.
1121      + This package is disabled by default since it increases storage.
1122    
1123    
1124    o testscript: added -cleanup option
1125    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1126                 b) enable to filter 2D fields.
1127    
1128    checkpoint44e_pre,post
1129    o re-wrote convective adjustment to use pre-calculated weights
1130      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1131      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1132      Original calls to convect() still in place.
1133    
1134    chkpt44d_pre,post
1135    o added missing EXCLUDE_MONITOR flags
1136    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1137      (incompatible typ in MIN/MAX expressions caused problems
1138      on IBM SP3)
1139    o in genmake added variable MAKEDEPEND
1140      plus resetting for case SunOS
1141    o added timer_stats.c routine for IBM SP3
1142    o removed variables in dynamics
1143    !!! I forgot to create tag chkpt44d_pre !!!
1144    !!! But chkpt44d_pre = chkpt44c_post    !!!
1145    
1146    o real fresh water flux implemented with non-linear free-surface.
1147    
1148    chkpt44c_pre,post
1149    o few fix (mask in shap_s2, EmPmR in external_field_load,
1150      USE_NATURAL_BCS in solve_for_P);
1151    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1152    
1153    checkpoint44b_pre/_post
1154    o merge of relevant stuff from the ecco-branch:

1159      - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
1160                      updated checkpointing_lev... lists for obcs
1161      - model/src: minor changes in forward_step, plot_field
1162                   added directive for divided adjoint in the_main_loop
1163      - pkg/mdsio: added mdsio_gl_slice
1164    
1165    o check parameters & config (chkpt44a_pre,post)
1166    o OBC and NonLin_FrSurf.
1167    
1168    checkpoint44
1169    o fix bug in mom_vi_del2uv

1181    
1182    checkpoint42
1183      Fixed AD-related problems:
1184    o Store directives up-to-date with re-arranged Adams-Bashforth
1185      (mainly thermodynamics.F)
1186    o New store directives for multi-dim. advection schemes
1187      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1188      * new common block and key passkey
1189      (mainly gad_advection.F)
1190    o Modified store directives for split of dynamics/thermodynamics
1191      for the case ALLOW_KPP
1192    o Cleaned argument list for timestep_tracer.F
1193    
1194    checkpoint41
1195    o re-formatted/added comments in prologues of key subroutines
1196      to work with protex
1197    
1198    checkpoint40
1199    o moved calc_gs, calc_gt and calc_tr1 back to model/src
1200    o added FLT (floats) package from Arne along with demo. experiment
1201    o re-arranged Adams-Bashforth scheme for tracers to allow easier
1202      implementation of forward-in-time forcing terms
1203    o more mods for non-linear free-surface including new variable
1204    o modified multi-dim method to work on cube
1205    o bug fix in KPP (from DM)
1206    
1207    checkpoint40pre9

1216      
1217    checkpoint40pre8
1218    o new package rw/
1219      Added method for dumping intermediate local arrays:
1220      mdsio_writetile - same as mdsio_writefield except works from inside
1221                        bi,bj loop
1222      mdsio_writelocal - same as mdsio_writetile except works for local
1223                         arrays
1224      write_local_r? - higher-level wrapper for mdsio_writelocal
1225      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1226      Example given at end of mom_vecinv.F that dumps some local arrays.
1227    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1228      control flux-form versus vector invariant code.
1229      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1230      or genmake -DISABLE ...
1231    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1232      (additional storing is now needed for case vecinv;
1233      currently nothing implemented to switch this storing off
1234      in case fluxform is used since no CPP flag available).
1235    
1236    checkpoint40pre7
1237    o bug fix in dynamics.F
1238      calc_viscosity called before k=1,Nr loop.
1239    o added some #ifdef's ALLOW_PASSIVE_TRACER
1240    o cleaned initialisations in ctrl_map_ini
1241      related to TAF
1242    
1243    checkpoint40pre6
1244    o split dynamics into thermodynamics & dynamics
1245    o corresponding split of calc_diffusivity into
1246      calc_diffusivity, calc_viscosity
1247      (kpp_calc_diff, kpp_calc_visc).
1248    o Added diffkr, kapgm to control variables
1249    o bug fix in gmredi_slope_limit for ldd97
1250    
1251    checkpoint40pre5
1252    o proper initialization of Adams-Bashforth time stepping
1253      + uses forward step for very first step of model (iter=0)
1254    o re-generated *all* output since almost all output is modified by this
1255      change (sorry but we've been putting this one off for about 2 years)
1256      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1257        *not* regenerated since they are already out of date and I don't
1258        want to create the impression that they are suddenly working.
1259    o removed KAP stuff for DEC's
1260    o modified/added many .cvsignore files in */code and */input
1261    o added new expt "solid-body.cs-32x32x1"
1262      + this uses an alternative form of ini_curvilinear_grid.F which
1263        is not necessarily any better than the current one...
1264    
1265    checkpoint40pre4
1266    o added re-initialisations of utrans,vtrans,rtrans in
1267      calc_common_factors which are crucial for TAF.
1268    o extended iMin,jMin range for calc_common_factors,
1269      calc_diffusivity
1270    o added option ALLOW_PASSIVE_TRACER
1271    o a few minor updates and fixes
1272    
1273    checkpoint40pre3
1274    o created calc_gtr1.F for gad package
1275    o split the_main_loop and re-introduced forward_step
1276    o some recomputations of nIter0 for TAMC
1277    
1278    checkpoint40pre2
1279    o Updated to latest branch of AJA, JMC
1280    o Added gradient check package
1281    o Added routines for passive tracer handling
1282    o Added carbon sequestration sensitivity experiment
1283    
1284    checkpoint39
1285     o Modifications and fixes to support TAMC
1286       (mainly missing or wrong directives)
1287     o Corrected common blocks when fooling TAMC to produce adjoint I/O
1288       in addummy_in_stepping
1289     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1290     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1291     o Included following packages:
1292       cal: calendar
1293       exf: external forcing
1294       ecco: essential routines to control use of cal, exf
1295             (NB: this is not the full ECCO environment)
1296     o disabled some packages by default in genmake
1297    
1298    checkpoint38
1299     o see notes_c37_adj.txt
1300     o corrected wrong layer index in external_forcing_t
1301     o replaced the_main_loop/forward_step by the_main_loop
1302     o removed forceoutput from write_state
1303       (replaced criteria for initial/final state)
1304     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1305    
1306    checkpoint37
1307     o mdsio.F routine split and packaged in pkg/mdsio
1308       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1309        used unless genmake -disable=mdsio)
1310     o allow a more precise surface-geopotential gradient for the atmosphere
1311       taking into account the change in space of Alpha (=1/rho) at the surface.
1312     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1313       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1314     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1315       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1316       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1317     o Time-Average diagnostics defined as a pseudo package "timeave".
1318     o pickup files : old pickup (before c35) did not work with new code (c35
1319       and after) unless activating 2 commented lines in initialise-varia.
1320     o Non-Hydrostatic pickup file Pb fixed.
1321     o bug with Rigid-lid version (since c35) fixed.  
1322    
1323    checkpoint36
1324     o implement Crank-Nickelson barotropic time-stepping
1325     o recover Time-Average diagnostics
1326     o fix Pb in checkpoint (PR#19)
1327     o AIM become a standard package ; clean unused CPP_kees
1328    
1329    checkpoint35
1330     o subtantial rewrite of dynamics.f
1331     o allows staggered time-stepping
1332     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
1333     o added bottom drag (linear + quadratic)
1334    
1335    checkpoint34
1336     o Modified exchange routines for correct reverse simulation.
1337     o Added verification output to comply with bug fix in impldiff.F
1338       as of c33 (exp2, natl_box).
1339     o Corrected store directives in dynamics.F
1340     o Corrected array boundaries in impldiff.F
1341     o Corrected array dimensions in gmredi.
1342       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
1343     o Added routine GLOBAL_SUM_INT to global_sum.F
1344     o Added mdsio_gl.F for ECCO purposes.
1345    
1346  checkpoint33  checkpoint33
1347   o Fixed bug in lower BC in impldiff.F   o Fixed bug in lower BC in impldiff.F
1348   o Fixed confusion about units of forcing arrays in FFIELDS.h   o Fixed confusion about units of forcing arrays in FFIELDS.h
