4      ==============================      ==============================
5    
6    checkpoint52d_post
7    o add infrastructure in model routines for fizhi and gridalt packages
8    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
9    o changes to permit hi-res, cubed-sphere, configuration
10      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
11      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
12      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
13        of surface winds for the cube
14      (A verification experiment, based on global_ocean.cs32x15, but with
15       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
16       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
17       complete with example surface forcing files and matlab scripts to look
18       at the output and compare it with that of global_ocean.cs32x15.)
19    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
20       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
21       to conform to the common rule.
22    o check-in the first version of the coupler + interfaces for multi-components
23       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
24       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
25       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
26       - ocean and atmos. share the same horizontal grid (no interpolation).
27       - exchanges between component and coupler is done in forward_step
28    o new verification experiment, cpl_aim+ocn:
29       coupled ocean - AIM atmosphere on cs32 grid.
30    
31    checkpoint52d_pre
32    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
33    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
34    
35    checkpoint52c_post
36    o Fixing OPTIONS files for use of exf:
37      - ALLOW_ECCO not needed
38      - ECCO_CPPOPTIONS.h should not be included from
39        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
40        as has been the case in the past
41      - All cal/exf related options are currently set in
42        single header file. Should remain so until we
43        agree on a consistent new policy.
44    o Removed all CPP options for cal package.
45      cal has no more CPP options.
46    o modified STOREs in GAD_ADVECTION
47    o corrected key comp. for passkey
48    
49    checkpoint52b_post
50    o new version: "thsice" of thermodynamic sea-ice pkg:
51     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
52     - modify fluxes but do not change theta directly;
53     - light cleaning of bulk_force pkg (still needed with thsice).
54     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
55       + output_thsice.txt to test thsice & bulk_force pkgs.
56    o put back grid & coriolis monitor output.
57    checkpoint52b_pre
58    
59    o call "do_the_model_io" at the beginning (=> dump initial state)
60    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
61    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
62      (need info on NUMBER_OF_PTRACERS)
63    o missing PTRACERS headers in some routines
64    o default tamc.h in pkg/autodiff supposed to crash
65      to ensure proper customization
66    
67    checkpoint52a_post
68    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
69      - moved surfaceTendencyTice from pkg/seaice to main code
70      - subroutine FREEZE_SURFACE now limits only surface temperature
71        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
72        => new output.txt for global_ocean.cs32x15 & global_with_exf
73      - keep the old version of FREEZE for backward compatibility;
74        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
75      - corresponding modifs for TAF directives
76    o added surface flux output variables to TIMEAVE_STATVARS
77    o time-averaged output for pkg/ptracers
78    o fix problem with ECCO-related divided adjoint

84    
85    checkpoint52 = ecco_c52_e35
86    o after testing adjoints of checkpoint51u_post
87    
88    checkpoint51u_post
89    o this is the post-merge tag of the ecco-branch
90      (needs another clean checkout and re-testing)
91    o various natl_box_adjoint configs and results
92      but no input fields
93    o obcs adjoint not yet merged!
94    o adding ECCO global 1x1 and 2x2 degree configs
95    o updated/extended some store directives for seaice
96    o pkg/ecco now containes ecco-specific part of cost function
97    o top level routines the_main_loop, forward_step
98      supersede those in model/src/
99      previous input data.cost now in data.ecco
100      (new namelist ecco_cost_nml)
101    o in ctrl/ cleaned some cross-dependencies and updated CPP options
102    
103    checkpoint51t_post
104    o this is the pre-merge tag of the ecco-branch
105    
106    checkpoint51s_post
107    o cleanup: removed various obsolete #define-s
108    o pkg/grdchk
109      - renamed 'ph-grd 3' to 'grad-res'
110      - merged from ecco-branch
111        (remaining bug fixes for obcs gradient checks)
112      - additional high-precision output for testreport
113        (grep for 'precision_grdchk_result')
114    
115    checkpoint51r_post
116    o cleaned up or removed CPP_OPTIONS.h files
117    o updated results for some of the tests to reflect the new
118      optfiles (-ieee: -O0 instead of -O3)
119    
120    checkpoint51q_post
121    o cd_code:
122      - moved cd_scheme.F -> cd_code_scheme.F
123      - separate read_checkpoint from cd_code_ini_vars.F
124      - separated cd_code part from write_checkpoint
125      - updated AD_SOURCE, generated .flow
126      - added CD_CODE_VARS.h to the_main_loop
127      - Moving cd_code specific store dir.s to pkg/cd_code
128    o ctrl package totally restructured
129      - pack/unpack now optional and decoupled from
130        xx_/adxx_ I/O
131      - ctrl_pack/unpack cleaned
132        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
133      - confined inclusion of AD_CONFIG.h to where necessary.
134    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
135    
136    checkpoint51p_post
137    o create initial cd_code package
138      - WARNING: the initialization of fields within packages
139        is broken because INI_FIELDS (where READ_CHECKPOINT is
140        called) is called *before* PACKAGES_INIT_VARIABLES.
141        This seems to be backwards since
142        1) its important to initially zero the entire field including
143           the "halo" region
144        2) zeroing needs to be done *before* reading pickup info
145           and the pickup call might or might not happen in any
146           particular run
147      - this needs an overhaul for R2
148    o cleanup verification/*/code/GMREDI_OPTIONS.h
149    o cleanup testreport
150

159    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
160    o bug fix in find_alpha.F for MDJWF:
161      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
162        change rho -> rho-rhoConst
163      - replace call find_rho to find_rhonum
164    o initialisation of rFlx extended to full array (required by TAF)
165      and shifted to thermodynamics
166    o removed PTRACERS.h in ptracers routine
167    o added surfacetendencyPtr to S/R parameter list pracers_forcing
168    o Correcting initialisations for fVerU, fVerV.

368        made the default because of faster convergence than ADI
369    
370    checkpoint50f_post
371    o exf totally restructured
372      - replaced all exf_set_ routines by one generic exf_set_gen.F

390     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
391       nearly a copy of kpp_transport_s
392     - there is no analogue to SurfaceTendencyS, so I have to use
393       gPtr(of the surface layer) instead
394    o add a new platform SunFire+mpi (SunFire 15000) to genmake
395    checkpoint50e_pre

417    
418    checkpoint50b_post
419    o store u*,v* in gU,V instead of in guNm1,gvNm1
420    o in order to put the momForcing out of the Adams-Bashforth:
421      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
422      to timestep.F
423    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
424    o re-generate output for highly sensitive test-exp:
425       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
426    
427    checkpoint50b_pre
428    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
429    o corrected CPP option mismatch in exf_Bulk... functions for case
430      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
431    
432    checkpoint50a_post
433    o Bug fix for merging between c50 and KPP.
434      ikey was passed from thermodynamics to kpp_calc via
435      common block rather than being recomputed in kpp_calc,
436      in contradiction with new key itdkey.
437      New key ikppkey created, and tamc.h headers updated.
438    
439    checkpoint50
440    - 2nd step of merge with ecco-branch:
441      merge changes in ecco-branch back into main trunk
442    - bug fix in find_alpha
443    - more storing in gmredi_calc_tensor.F, kpp_routines.F
444    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
445    - merged some sliced AD support routines
446    
447    checkpoint49
448    merged from ecco-branch:
449    o exf:
450      - Enable initialisation of forcing fields to constant
451        (runtime) values.
452      - in exf_getffields.F
453        Reduce i-/j-loop to interior domain, discarding overlaps.
454        That also fixes wrong TAF-key computations for key_1, key_2
455        with bulf formulae.
456      - exf_init.F modify #ifdef for exf_init_evap
457      - exf_getffieldrec.F, ctrl_getrec.F
458        The following INT-usages are not safe:
459          fldsecs  = int(fldsecs/fldperiod)*fldperiod
460          fldcount = int(fldsecs/fldperiod) + 1
461        and were modified.
462    o autodiff: checkpoint_lev...
463      - updated storing for bulk formulae (some arrays were missing)
464      - added state for seaice package
465      - synchronized with main branch
466    o DIVA:
467      Modif.s in
468      - the_main_loop.F
469      - the_model_main.F
470      and added cost_final_restore.F cost_final_store.F
471      o With these changes, it is possible to fully separate
472        the first forward run to compute the cost function (mdthe_main_loop)
473        and adjoint runs over individual DIVA intervals (adthe_main_loop)
474        into separate model executions.
475        This enables better tuning of DIVA to given queue sizes.
476      o Loss of cost function value in consecutive DIVA runs is
477        fixed by storing to 'costfinal' file.
478      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
479        beginning/end of adjoint integration is accounted for.
480      The current changes apply to TAF-1.4.26.
481      TAF has one remaining bug, requiring one manual change
482      (see MITgcm manual).
483    o cal: synchronized between MAIN and ecco-branch
484    
485    checkpoint48i_post
486    o Changes to restore differentiability of code w.r.t. previous tag
487      (mostly adding new routines to make list and replacing
488      pressure by totPhiHyd).
489    o Updated and merged grdchk package
490      - has both ADM and TLM checks
491      - works for single- and multi-proc.
492      - output cleaned
493      - worked successfully for parallel DIVA
494    o genmake:
495      - Adding -platform=SP4
496      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
497    o Modif. for DIVA:
498      ctrl_unpack should not be called in intermediate DIVA interval.
499      (similar thing would apply for active files such as
500      tbar, sbar, psbar, which should not be reinitialised;
501      only relevant for ecco-branch)
502    
503    checkpoint48h_post
504    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
505    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
506    o Added SEAICE_initialHEFF to pkg/seaice
507    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
508    
509    checkpoint48g_post
510    --- EOS:
511    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
512      store total Potential in totPhyHyd for diagnostics & EOS.
513    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
514    --- Pressure/geopotential gradient:
515    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
516    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
517      ( changes results of global_ocean_pressure )
518    o NLFS + z-coord.: add eta*Rho' contribution.
519    o accurate phiHyd when using interface-W at the middle between 2 centers
520     ( changes results of ideal_2D_oce )
521    o includes r* 2nd term in potential gradient.
522    
523    checkpoint48f_post
524    Merging from release1_p12:
525    o Modifications for using pkg/exf with pkg/seaice
526      - improved description of the various forcing configurations
527      - added basic radiation bulk formulae to pkg/exf
528      - units/sign fix for evap computation in exf_getffields.F
529      - updated verification/global_with_exf/results/output.txt
530    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
531      (SBO) core products, including oceanic mass, center-of-mass,
532      angular, and bottom pressure (see pkg/sbo/README.sbo).
533    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
534      to avoid negative values in shallow regions.
535      - updated verification/natl_box/results/output.txt
536      - updated verification/lab_sea/results/output.txt
537    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
538    o Added useSingleCpuIO option (see PARAMS.h).
539    o Updated useSingleCpuIO option in mdsio_writefield.F to
540      work with multi-field files, e.g., for single-file pickup.
541    o pkg/seaice:
542      - bug fix in growth.F: QNET for no shortwave case
543      - added HeffFile for specifying initial sea-ice thickness
544      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
545    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
546      kpp_transport_t.F, forward_step.F, and the_main_loop.F
547    o pkg/seaice:
548      - adjoint-friendly modifications
549      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
550    
551    checkpoint48e_post
552    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
553    o dynamics: change definition of computational domain & adapt mom_fluxform
554      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
555    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
556        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
557        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
558        global_ocean.90x40x15 global_with_exf global_ocean_pressure
559        inverted_barometer solid-body.cs-32x32x1
560      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
561    
562    checkpoint48d_post
563    o in preparation for r*:
564     a) use pre-computed gradient of hydrostatic potential:
565        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
566     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
567        => affects results of glob_oce_pressure (different truncation error)  
568      update output.txt of ideal_2D_oce & global_ocean_pressure
569    
570    checkpoint48d_pre
571    o in preparation for r*:
572      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
573      pass the 2 comp. of the grad. as arguments to momentum S/R.
574      but for the moment, only used if it does not change the results.
575    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
576    
577    checkpoint48c_post
578    Modifications in treatment of initial flux forcing controls
579    to avoid extra storing of flux fields.
580    
581    checkpoint48c_pre
582    o Added tidal_basin_2d experiment (currently 1D!)
583    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
584    
585    checkpoint48b_post
586    o r* coordinate added in #ifdef NONLIN_FRSURF block.
587     (modification to pressure gradient not yet implemented)
588    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
589      (for U & V) that are used for vertical advection of momentum.
590    
591    checkpoint48a_post
592    o In preparation for r*, use temp. array to compute vertical transport
593       in flux-form momentum pkg. => change results of few test-exp.
594      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
595                        lab_sea, natl_box & plume_on_slope
596    
597    checkpoint48
598    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
599    
600    checkpoint47j_post
601    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
602    o moved adexch from forward_step to addummy_in_stepping
603    o added exch in ctrl_map_...
604    o aveFreq.=0. at end of cost_final to avoid overwrite in
605      reverse checkpointing loop
606    o Yet more changes in gmredi:
607      * adgmredi_calc_tensor
608        avoiding all recomputation of gmredi_slope_limit
609      * adgmredi_x/y/rtransport
610        added flag for excessive storing to avoid recomp. of
611        u/v/rtans, dTdx/y/z
612        -> this is not really necessary and very memory-consuming
613      * adgmredi_slope_psi:
614        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
615      * gmredi_slope_limit
616        re-activated full calculation of taperfct for case 'ac02'
617    o updating verification/ adjoints of carbon, global_ocean.90x40x15
618    
619    checkpoint47i_post
620    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
621    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
622      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
623    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
624    o gmredi: fix few bugs.
625    
626    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
627    This will be a good checkpoint to plug into the ecco-branch.
628    o few modif.'s to get latest version adjointed
629      (mainly kick out code in ini_linear_phisurf)
630    o modif's to run adjoint with exactConserv
631    o case GM_BOLUS_ADVEC should be cleaned
632      S/R gmredi_slope_psi should be cleaned
633    o verification/carbon now has exactConserv=.TRUE.
634    
635    checkpoint47g_post
636    o time-average AIM output: becomes independent from statvars time-average
637      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
638    o After TAF bug fix:
639      Tested adjoint of gmredi package.
640      Tests were done with checkpoint47 rather than with latest
641      checkpoint47f_post since the latter is broken for the adjoint
642      verification/carbon/ contains both ADM and TLM gradient checks.
643    Here they are, before they get changed/lost/stolen.
644    Mostly modif.'s to fix numerical sensitivities.
645    Gradient checks OK for
646    - GM_taper_scheme:
647      * clipping
648      * ac02
649      * linear
650      * glw91
651      * dm95
652      * ldd97
653    - GMREDI_OPTIONS:
654      * GM_VISBECK_VARIABLE_K
655      * GM_NON_UNITY_DIAGONAL
656      * GM_EXTRA_DIAGONAL
657      * GM_BOLUS_ADVEC
658    in conjunction with data.gmredi parameters to be checked in
659    in a few minutes under verification/carbon/code/
660    
661    checkpoint47f_post
662    Merging from release1_p10:
663    o modifications for using pkg/exf with pkg/seaice
664      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
665        and SEAICE_EXTERNAL_FLUXES
666      - pkg/exf CPP options EXF_READ_EVAP and
667        EXF_NO_BULK_COMPUTATIONS
668      - usage examples are Experiments 8 and 9 in
669        verification/lab_sea/README
670      - verification/lab_sea default experiment now uses
671        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
672    
673    checkpoint47e_post
674    o created a tag prior to creating a branch
675    
676    checkpoint47d_post
677    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
678      at the bottom boundary had an erroneous half slip boundary condition
679    o added bottom drag and no slip boundary condition capabilities to
680      oceanic pressure coordinates code
681    o added new verification experiment global_ocean_pressure, this experiment is
682      also described in the tutorial section of the manual
683    checkpoint47d_pre
684    
685    checkpoint47c_post
686    o Added a verification experiment for a global cubed-sphere ocean run
687      -  verification/global_ocean.cubed32x32x30
688      -  uses pkg/therm_seaice and pkg/bulk_forcing
689    
690    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
691    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
692      when using P-coordinate; only implemented for atmospheric config.
693    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
694      NOTES: requires option NONLIN_FRSURF to be "#define".
695    o update advect_xz/results/output.txt (left from checkpoint44g_post)
696    
697    checkpoint47b_post
698    Merging from release1_p9:
699    o pkg/seaice
700      - removed GOTO's and added taf directives
701      - double precision constants to reduce the g77 (Linux)
702        to F77 (SGI) differences reported in release1_p8
703    o tools/genmake
704      - added SGI options
705    o verification/testscript
706      - updated to that of checkpoint47a_post
707    o verification/global_ocean.90x40x15/input/eedata
708      - modified for SGI f77 compatibility
709    o verification/lab_sea
710      - added description of sea-ice model
711      - added missing matlab routines
712      - added test of thermodynamics parallelization
713    
714    checkpoint47a_post
715    o new pkg: aim_v23
716     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
717       for now, keep the same surface forcing as before.
718     - Part-Cell implemented into AIM; check that Heat & Water are conserved
719     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
720     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
721    o add diagnostic of surface correction term in monitor output
722    
723    o bulk_force and therm_seaice
724    - Two packages:  bulk_force (Bulk forcing)
725      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
726    - Earlier integration from Stephaine Dutkiewicz
727      and Patrick Heimbach.
728    - Two ifdef statements for compile time,
729       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
730    
731    checkpoint47
732    differentiable version of checkpoint46n_post
733    o bug fix in quasihydrostaticterms
734    o * "clean" adjoint code (in terms of extensive recomputations)
735        can now be obtained for all GMREDI options (i.e. for
736        - GM_VISBECK_VARIABLE_K
737        - GM_NON_UNITY_DIAGONAL
738        - GM_EXTRA_DIAGONAL
739        - GM_BOLUS_ADVEC )
740      * However, wrong gradient check problem remains unsolved.
741      * New CPP options have been introduced for different
742        tapering schemes
743    o external_fields_load now part of differentiation list
744    o pressure needs multiple storing;
745      would be nice to have store_pressure at beginning or
746      end of forward_step, e.g. by having phiHyd global (5-dim.)
747      (NB: pressure is needed for certain cases in find_rho,
748      which is also invoked through convective_adjustment).
749    o recomputations in find_rho for cases
750     'JMD95'/'UNESCO' or 'MDJWF' are OK.
751    o #define ATMOSPHERIC_LOADING should be differentiable
752    o ini_forcing shifted to begining of initialise_varia
753    o Incorporating QNVS line search routines into MITgcm
754      (this is separate code, and therefore not under pkg)
755      lsopt/, optim/
756    o Updated verification/carbon/
757      - #define GM_VISBECK_VARIABLE_K
758      - GM_taper_scheme    = 'ldd97'    
759    
760    checkpoint46n_post
761    Merging from release1_p8:
762    o verification/natl_box:
763      updating new external_fields_load routine
764    o New package: pkg/seaice
765      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
766      The sea-ice code is based on Hibler (1979-1980).
767      Two sea-ice dynamic solvers, ADI and LSR, are included.
768      In addition to computing prognostic sea-ice variables and diagnosing
769      the forcing/external data fields that drive the ocean model,
770      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
771      The implied surface heat flux is then stored in variable
772      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
773      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
774      non-local transport term.  Because this call precedes model
775      thermodynamics, temperature under sea-ice may not be "exactly" at
776      the freezing point by the time theta is dumped or time-averaged.
777      N.B.: fairly large differences in accuracy occur across
778            different platforms/compilers; comparison between
779            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
780            generated output gives:
781       T           S           U           V
782      C D M    c        m  s        m  s        m  s        m  s

786    
787      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
788    o GAD:
789      - generated new common blocks to account for call of
790        same gad routines with differing traceridentities
791        (needed to modify tracerIdentity indices in GAD.h)
792      - generated separate common blocks for case useCubedSphereExchange
793        (Department of Futurology)
794      - parameter lists to gmredi_?transport: added tracerIdentity
795      - added new key indices to tamc.h
796    o external_fields_load:
797      - added this routine to TAF list
798      - needed to make some common blocks global and additional storing
799        along the same lines as exf package (checkpoint_lev?_directives.h)
800    o exf:
801      updated external forcing package
802      - bug fixes carried over from ecco-branch
803        (missing OBCS_OPTIONS.h in two routines)
804      - enable easy to use "no forcing".
805      - added exf I/O for atmospheric loading
806      - added exf I/O for runoff data
807      - transfered scaling between exf <-> MITgcm to exf namelist
808    o Adding new verification experiment global_with_exf.
809      This verification experiment is almost identical to the
810      global_ocean.90x40x15 experiment, except that it uses
811      the exf (and cal) package instead of the
812      external_fields_load routine (cf README file).
813    
814    checkpoint46m_post
815    o modified testscript to return -- when there are no lines of "%MON" output
816    o added new flag "quasiHydrostatic" for QH mode
817      and new routine quasihydrostaticterms()
818    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
819      New routine: mom_u_coriolis_nh()
820    o fixed sign of non-hydrostatic metric terms in u and v equations.
821      Depend on correct sign of gravitySign.
822    o added work.pc* to .cvsignore in aim directories using ifc
823    o introduced flag for controllin non-hydrostatic metric terms
824    o removed gravitySign from PARM04
825    o switched to g77/ifc from pgf77 in aim experiments
826    
827    checkpoint46l_post
828    o made convective adjustment work with pressure coordinates:
829     - changed the direction of k-loop in convective_adjustment.F for the
830       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
831     - adjusted the reference pressure k-index in convective_adjustment.F
832     - adjusted the convection condition in convect.F (in analogy to
833       calc_ivdc.F)
834     - convective_adjustment no longer computes anything on the halos
835     - removed the warnings about negative salinity from find_rho.F and
836       find_alpha.F; instead the new routine look_for_neg_salinity, called
837       at the beginning of find_rho, find_alpha, and find_beta, does a
838       check of the entire slice, if CPP-option
839       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
840    checkpoint46l_pre
841    
842    checkpoint46k_post
843    o fixed the verification/global_ocean.90x40x15 experiment:
844     - new bathymetry (the world according to A., JMC, and M.)
845     - new initial fields and forcing fields (*.bin files)
846     - new POLY3.COEFFS (for the next release one should switch to a full
847       equation of state: JMD95P or MDJWF)
848     - fixed several errors and redundancies in the data file
849     - experiment uses looped cells
850     - added matlab directory with diagnostic scripts for plotting of output
851    
852    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
853     - read AIM physics parameters from a file (data.aimphys)
854     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
855    
856    checkpoint46j_post
857    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
858    o move wVel computation at the end of the time step, in S/R integr_continuity
859    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
860    o update timeave pkg for wVel diagnostic.
861    checkpoint46j_pre
862    
863    checkpoint46i_post
864    o Clean up AIM package (and keep the results unchanged):
865      include CPP_OPTION and use IMPLICT NONE in all routines ;
866      declare all the variables _RL ; use _d 0 for all numerical constants.
867      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
868    
869    checkpoint46h_post
870    o cleaned up the use of rhoNil and rhoConst.
871      - rhoNil should only appear in the LINEAR equation of state, everywhere
872        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
873        and the dynamical equations are all divided by rhoConst
874    o introduced new parameter rhoConstFresh, a reference density of fresh
875      water, to remove the fresh water flux's dependence on rhoNil. The default
876      value is 999.8 kg/m^3
877    o cleanup up external_forcing.F and external_forcing_surf.F
878      - can now be used by both OCEANIC and OCEANICP
879    checkpoint46h_pre
880    
881     Added code to convert surface volume flux (fresh water) into
882     a mass flux when using P coordinates in the ocean (OCEANICP).
883     Note: It assumes you have set rho0=rhoConst=density of fresh water.
884    
885    checkpoint46g_post
886    o Include a new diagnostic variable phiHydLow for the ocean model
887      - in z-coordinates, it is the bottom pressure anomaly
888      - in p-coordinates, it is the sea surface elevation
889      - in both cases, these variable have global drift, reflecting the mass
890        drift in z-coordinates and the volume drift in p-coordinates
891      - included time averaging for phiHydLow, be aware of the drift!
892    o depth-dependent computation of Bo_surf for pressure coordinates
893      in the ocean (buoyancyRelation='OCEANICP')
894      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
895        Theta, Salinity, and Pressure in the parameter list. This routine is
896        presently contained in find_rho.F. This routine does not give the
897        correct density for 'POLY3', which would be a z-dependent reference
898        density.
899    o cleaned up find_rho
900      - removed obsolete 'eqn' from the parameter list.
901    o added two new verification experiments: gop and goz
902      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
903    checkpoint46g_pre
904    
905    checkpoint46f_post
906    o Enable tangent linear (forward mode) gradient checks:
907      - extended active file handling to g_... files
908      - added TANGENT_SIMULATION to theSimulationMode
909      - extended grdchk package accordingly
910    o added tangent linear setup in verification/carbon/code_ftl
911    o added adjoint setup in verification/front_relax/code_ad
912    
913    checkpoint46e_post
914    o Added new equation of state -> MDJWF
915      - EOS of McDougall et al., 2002, JAOT, submitted
916      - caveat: the equation of state is only valid for a smaller (more
917        realistic?) range of values than JMD95P/Z and UNESCO
918      - added masks to the calculation of pressure in store_pressure
919      - added more check values for density in check_eos (ini_eos.F), some of
920        the old check values are out of the range of the MDJWF-eos, so don't
921        expect perfect matches for those
922    checkpoint46e_pre
923    
924    checkpoint46d_post
925    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
926      'OCEANICP', also initialised field pressure correctly in ini_eos in the
927      case of pressure coordinates. eosType='JMD95Z' in
928      combination with buoyancyRelation='OCEANICP' now causes an error.
929    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
930      in find_alpha/beta.
931    checkpoint46d_pre
932    
933    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
934      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
935    
936    checkpoint46c_post
937    o Changes necessary for ocean in p-coordinates
938     -  Added new buoyancy relation = 'OCEANICP'
939     -  Added new parameters = gravitySign (this used to be contained inside
940        the factor dRdZ which I added when we first switched to R coordinates).
941     X GM/Redi is not compatible (yet)
942     X bottom drag and no-slip need to be debugged.
943    checkpoint46c_pre
944    
945    checkpoint46b_post
946    o Added new equation of state -> JMD95Z and JMD95P
947      - EOS of Jackett and McDougall, 1995, JAOT
948      - moved all EOS parameters into EOS.h
949      - new routines ini_eos.F, store_pressure.F
950    o Added UNESCO EOS, but not recommended because it requires
951      in-situ temperature (see JMD95)
952    o Modified formatting for knudsen2.f in utils/knudsen2 and added
953      unesco.f to be used with POLY3
954    checkpoint46b_pre
955    
956    checkpoint46a_post
957    o Added (atmospheric) pressure loading
958      - new field in FFIELDS.h, etc...
959      - new cpp flag ATMOSPHERIC_LOADING
960    o Changed hFacC to _hFacC in calc_phi_hyd.F
961    o Added SHORTWAVE_HEATING to some files for consistency
962    checkpoint46a_pre
963    
964    checkpoint46
965    further merges from release1_p5
966    o new ctrl package
967      - adopted from ECCO environment to enable optimization
968      - added Eliassen Palm fluxes to controls
969    o added Eliassen Palm flux controls to gradient check package
970    o cost package
971      - Compatible with new ctrl package
972      - added Eliassen Palm cost hooks
973      - modif's of existing cost functions
974    o Adjoint-related bug fixes in kpp:
975      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
976      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
977    o autodiff package
978      - flow directives:
979        + new for S/R do_the_model_io
980        + enhanced for S/R checkpoint
981        + new gmredi.flow
982      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
983        disable adcommon.h/g_common.h by default.
984      - fixed problem for adjoint of global_max
985    o modified verification/carbon/
986    o New setup for adjoint of global_ocean

988    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
989    o incorporated hooks for sponge layer code (external_forcing.F)
990    
991    checkpoint45d_post
992    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
993    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
994      (affects plume_on_slope "cg2d" output)
995    o add new parameter deltaTfreesurf for free-surface time stepping
996    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
997    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
998    o change phiMin in exp1 (to agree with documentation)
999    o add new flags:
1000     - T,S forcing inside/outside Adams-Bashforth
1001     - turn off temp,salt advection and/or forcing
1002     - for each tracer, define internal flag for multiDimAdvection & A-B
1003    o monitor: change definition of KE to check conservation of Energy
1004    
1005    checkpoint45c_post
1006    o Removed f90 comments ("!")
1007    o Modified initialisations to enable exf package for MITgcm

1011      - modified format of standard output
1012    
1013    checkpoint45b_post
1014    o cleaned exchange calls in cg2d
1015    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1016    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1017      to configure barotropic setup (Martin Losch)
1018    o moved some initialisations within bi,bj loop in dynamics
1019      (TAF flow dependency)
1020    o in initialise_varia, moved call packages_init_variables
1021      before convective_adjustment_init
1022      (corresponding adjustment of TAF tape initialisation).
1023    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1024    
1025    checkpoint45a_post
1026    o compute Rho over the whole domain (extend iMin,jMin indices)
1027    o specific exchange for X-slice domain (case Ny=1)
1028    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1029    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1030    
1031    checkpoint44h_post = checkpoint45
1032    o Fix to restore differentiability:
1033      place at which packages_init_variables is called in
1034      initialise_varia is crucial for reverse control flow.
1035    o modifications in GMRedi to enable stable adjoint
1036      (corresponding modif's in thermodynamics, dynamics)
1037    o added missing hook for sponge layer code in external_forcing
1038    o modified test cost functions
1039    o storing in gad_advection (plus removal of write(0,*)!
1040    o missing headers TR1.h added in convective_adjustment routines

1043    o modified carbon verif.
1044    
1045    checkpoint44h_pre
1046    o vertical grid option: allow to put the Interface at the middle between
1047      2 cell-centers ; replace delZ in pkg/kpp by drF.
1048    o GM Advective form: Tracers are advected using the residual transport (=
1049      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1050    
1051    checkpoint44g_post
1052    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1053      results) ; ifdef missing in thermodynamics.F
1054    
1055    checkpoint44f_pre,checkpoint44f_post
1056    o added PTRACERS package
1057      This allows an arbitrary number of passive tracers to be integrated
1058      forward simultaneously with the dynamicaly model.
1059      + Implemented so far:
1060        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1061        - I/O and checkpointing
1062        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1063      + Not implemented so far:
1064        - KPP
1065        - OBCS
1066      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1067        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1068        line in data.pkg.
1069      + This package is disabled by default since it increases storage.
1070    
1071    
1072    o testscript: added -cleanup option
1073    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1074                 b) enable to filter 2D fields.
1075    
1076    checkpoint44e_pre,post
1077    o re-wrote convective adjustment to use pre-calculated weights
1078      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1079      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1080      Original calls to convect() still in place.
1081    
1082    chkpt44d_pre,post
1083    o added missing EXCLUDE_MONITOR flags
1084    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1085      (incompatible typ in MIN/MAX expressions caused problems
1086      on IBM SP3)
1087    o in genmake added variable MAKEDEPEND
1088      plus resetting for case SunOS
1089    o added timer_stats.c routine for IBM SP3
1090    o removed variables in dynamics
1091    !!! I forgot to create tag chkpt44d_pre !!!
1092    !!! But chkpt44d_pre = chkpt44c_post    !!!
1093    
1094    o real fresh water flux implemented with non-linear free-surface.
1095    
1096    chkpt44c_pre,post
1097    o few fix (mask in shap_s2, EmPmR in external_field_load,
1098      USE_NATURAL_BCS in solve_for_P);
1099    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1100    
1101    checkpoint44b_pre/_post
1102    o merge of relevant stuff from the ecco-branch:
1103      - genmake: removed $S64 overwrite for case SunOS
1104      - pkg/exf: update and corrections for field swapping and obcs
1105      - pkg/ecco: parameter lists for the_model_main, the_main_loop
1106                  harmonized between ECCO and MITgcm
1107      - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
1108                      updated checkpointing_lev... lists for obcs
1109      - model/src: minor changes in forward_step, plot_field
1110                   added directive for divided adjoint in the_main_loop
1111      - pkg/mdsio: added mdsio_gl_slice
1112    
1113    o check parameters & config (chkpt44a_pre,post)
1114    o OBC and NonLin_FrSurf.
1115    
1116    checkpoint44
1117    o fix bug in mom_vi_del2uv
1118    o select when filters are applied ; add options to zonal_filter (data.zonfilt)

1128    o some final mods for gradient check, adjoint,...
1129    
1130    checkpoint42
1131      Fixed AD-related problems:
1132    o Store directives up-to-date with re-arranged Adams-Bashforth
1133      (mainly thermodynamics.F)
1134    o New store directives for multi-dim. advection schemes
1135      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1136      * new common block and key passkey
1137      (mainly gad_advection.F)
1138    o Modified store directives for split of dynamics/thermodynamics
1139      for the case ALLOW_KPP
1140    o Cleaned argument list for timestep_tracer.F
1141    
1142    checkpoint41
1143    o re-formatted/added comments in prologues of key subroutines
1144      to work with protex
1145    
1146    checkpoint40
1147    o moved calc_gs, calc_gt and calc_tr1 back to model/src
1148    o added FLT (floats) package from Arne along with demo. experiment
1149    o re-arranged Adams-Bashforth scheme for tracers to allow easier
1150      implementation of forward-in-time forcing terms
1151    o more mods for non-linear free-surface including new variable
1152    o modified multi-dim method to work on cube
1153    o bug fix in KPP (from DM)
1154    
1155    checkpoint40pre9
1156    o added DST advection schemes
1157    o fix MPI bug on SGI's
1158    o modifications for non-linear free-surface
1159    o fixed conditionals for fixed flow/passive tracer only mode
1160    o added tension/strain form of stress tensor
1161    o changes to commenting of arguments for TAF/TAMC
1162    o added/updated many matlab scripts
1163    o added multi-dimensional advection method for tracers
1164      
1165    checkpoint40pre8
1166    o new package rw/
1167      Added method for dumping intermediate local arrays:
1168      mdsio_writetile - same as mdsio_writefield except works from inside
1169                        bi,bj loop
1170      mdsio_writelocal - same as mdsio_writetile except works for local
1171                         arrays
1172      write_local_r? - higher-level wrapper for mdsio_writelocal
1173      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1174      Example given at end of mom_vecinv.F that dumps some local arrays.
1175    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1176      control flux-form versus vector invariant code.
1177      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1178      or genmake -DISABLE ...
1179    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1180      (additional storing is now needed for case vecinv;
1181      currently nothing implemented to switch this storing off
1182      in case fluxform is used since no CPP flag available).
1183    
1184    checkpoint40pre7
1185    o bug fix in dynamics.F
1186      calc_viscosity called before k=1,Nr loop.
1187    o added some #ifdef's ALLOW_PASSIVE_TRACER
1188    o cleaned initialisations in ctrl_map_ini
1189      related to TAF
1190    
1191    checkpoint40pre6
1192    o split dynamics into thermodynamics & dynamics
1193    o corresponding split of calc_diffusivity into
1194      calc_diffusivity, calc_viscosity
1195      (kpp_calc_diff, kpp_calc_visc).
1196    o Added diffkr, kapgm to control variables
1197    o bug fix in gmredi_slope_limit for ldd97
1198    
1199    checkpoint40pre5
1200    o proper initialization of Adams-Bashforth time stepping
1201      + uses forward step for very first step of model (iter=0)
1202    o re-generated *all* output since almost all output is modified by this
1203      change (sorry but we've been putting this one off for about 2 years)
1204      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1205        *not* regenerated since they are already out of date and I don't
1206        want to create the impression that they are suddenly working.
1207    o removed KAP stuff for DEC's
1208    o modified/added many .cvsignore files in */code and */input
1209    o added new expt "solid-body.cs-32x32x1"
1210      + this uses an alternative form of ini_curvilinear_grid.F which
1211        is not necessarily any better than the current one...
1212    
1213    checkpoint40pre4
1214    o added re-initialisations of utrans,vtrans,rtrans in
1215      calc_common_factors which are crucial for TAF.
1216    o extended iMin,jMin range for calc_common_factors,
1217      calc_diffusivity
1218    o added option ALLOW_PASSIVE_TRACER
1219    o a few minor updates and fixes
1220    
1221    checkpoint40pre3
1222    o created calc_gtr1.F for gad package
1223    o split the_main_loop and re-introduced forward_step
1224    o some recomputations of nIter0 for TAMC
1225    
1226    checkpoint40pre2
1227    o Updated to latest branch of AJA, JMC
1228    o Added gradient check package
1229    o Added routines for passive tracer handling
1230    o Added carbon sequestration sensitivity experiment
1231    
1232    checkpoint39
1233     o Modifications and fixes to support TAMC
1234       (mainly missing or wrong directives)
1235     o Corrected common blocks when fooling TAMC to produce adjoint I/O
1236       in addummy_in_stepping
1237     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1238     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1239     o Included following packages:
1240       cal: calendar
1241       exf: external forcing
1242       ecco: essential routines to control use of cal, exf
1243             (NB: this is not the full ECCO environment)
1244     o disabled some packages by default in genmake
1245    
1246    checkpoint38
1247     o see notes_c37_adj.txt
1248     o corrected wrong layer index in external_forcing_t
1249     o replaced the_main_loop/forward_step by the_main_loop

1251       (replaced criteria for initial/final state)
1252     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1253    
1254    checkpoint37
1255     o mdsio.F routine split and packaged in pkg/mdsio
1256       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1257        used unless genmake -disable=mdsio)
1258     o allow a more precise surface-geopotential gradient for the atmosphere
1259       taking into account the change in space of Alpha (=1/rho) at the surface.
1260     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1261       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1262     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1263       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1264       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1265     o Time-Average diagnostics defined as a pseudo package "timeave".
1266     o pickup files : old pickup (before c35) did not work with new code (c35
1267       and after) unless activating 2 commented lines in initialise-varia.
1268     o Non-Hydrostatic pickup file Pb fixed.
1269     o bug with Rigid-lid version (since c35) fixed.  
1270    
1271    checkpoint36
1272     o implement Crank-Nickelson barotropic time-stepping
1273     o recover Time-Average diagnostics
1274     o fix Pb in checkpoint (PR#19)
1275     o AIM become a standard package ; clean unused CPP_kees
1276    
1277    checkpoint35
1278     o subtantial rewrite of dynamics.f
1279     o allows staggered time-stepping
1280     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
1281     o added bottom drag (linear + quadratic)
1282    
1283    checkpoint34
1284     o Modified exchange routines for correct reverse simulation.
1285     o Added verification output to comply with bug fix in impldiff.F
1286       as of c33 (exp2, natl_box).
1287     o Corrected store directives in dynamics.F
1288     o Corrected array boundaries in impldiff.F
1289     o Corrected array dimensions in gmredi.
1290       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
1291     o Added routine GLOBAL_SUM_INT to global_sum.F
1292     o Added mdsio_gl.F for ECCO purposes.
1293    
1294    checkpoint33
1295     o Fixed bug in lower BC in impldiff.F
1296     o Fixed confusion about units of forcing arrays in FFIELDS.h
1297       namely Fu,Fv,Qnet,Qsw,EmPmR:
1298       - Removed verification/natl_box/code/external_fields_scale.F
1299         (did not differ from that in model/src)
1300       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
1301         (see FFIELDS.h for description)
1302       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
1303         kpp_calc.F and kpp_transport_t.F
1304       - Removed model/src/external_fields_scale.F and calls to it
1305       - verification/natl_box uses flux data with "atmospheric" sign so
1306         a special version of external_fields_load.F is used to
1307         change the data as it's read in. This way, the arrays
1308         have the right units and signs at all times tha a user could
1309         possibly use them.
1310     o Corrected genmake to delete a temporary file during configuration
1311    
1312    checkpoint32
1313     o Scaling of forcing fields moved from external_forcing.F to
1314       external_fields_scale.F, called directly after loading fields.
1315     o Surface relaxation terms added to surface tendency fields in
1316       extra subroutine.
1317     o impldiff.F changed to avoid storing by TAMC of huge intermediate
1318       fields.
1319     o Changes in GMRedi to comply with packaging structure.
1320     o Modifications and bug fixes in KPP package.
1321     o Verification experiment for KPP added (verification/nat_box/)
1322    
1323    checkpoint31
1324     o Packages interface brought in line with defined standard
1325       -> new routines packages_...F
1326       -> changes in initialise_fixed.F, initialise_varia.F
1327       -> enables initialisation interface for ECCO package
1328     o Rescaling of external forcing fields immediately after read
1329       (removed from external_forcing.F)
1330       -> new: surface_fields_scale.F
1331       -> affects ini_foorcing.F, external_fields_load.F
1332     o Computation of surface tendencies before tendency updates.
1333       -> new: external_forcing_surf.F
1334     o Change of variable names useGMRedi, useKPP, useECCO
1335     o Further changes in dynamics.F, impldiff.F for TAMC
1336     o Tested for experiments 0, 2, 4.
1337       - not yet tested for GMRedi.
1338       - not yet tested for KPP.
1339    
1340    checkpoint30
1341     o Updates for OBCs
1342     o New experiment for test OBCs (internal_wave)
1343     o New output.txt in verification/exp4/results/
1344     o Updates for KPP: calculation of viscosity corrected, new variables
1345       kpp_dumpFreq and kpp_taveFreq
1346     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
1347       and entry for T90 in genmake

1350     o packaged KPP and GM/Redi
1351    
1352    checkpoint28
1353     o Corrected initialization of hFacMin for difference vertical coordinates
1354     o Modified calculation of partial cell thickness to more robust algorithm
1355     o config_summary.F: replaced write_1D_... by write_0D_...
1356       read_write.F: added subroutines write_0D_...
1357     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
1358       included some initialisations required for TAMC.
1359     o routine calc_isoslopes: modified sqrt computation to make it
1360       differentiable for zero argument.
1361     o routines dynamics, impldiff:
1362       included store directives and tape key computations required for TAMC.
1363     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
1364    
1365    checkpoint27
1366     o fixed calc_isoslopes() to so that cancellation of terms in tensor
1367       formulation works properly with variable resolution.
1368     o restructured the calling tree between the_model_main() and dynamics()
1369     o split initialise() into initialise_fixed() and initialise_varia()
1370     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
1371       in new routine ini_psurf()
1372    
1373    checkpoint26
1374     o moved some #ifdef in optional routines to encompass everything
1375       except the argument declarations. This was using up some memory.
1376     o fixed macros like _ADT to work with both versions of Linux cpp
1377     o cleaned up some unused and uninitialized variables
1378       (helps when debugging with strict compile options)
1379     o split up CPP_EEOPTIONS.h into options and macros
1380       (macros are now in eesupp/inc/CPP_EEMACROS.h)
1381     o patch for 2 processor JAM mode
1382    
1383    checkpoint25
1384     o updates for OBCs and NH
1385     o dramatically reduced memory usage
1386     o added "JAM" routines for use on Artic network

1388     o added a diagnostic of convective index
1389     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
1390       (this is was partly for OBCs and NH but also in anticipation of
1391        an explicit free-surface option)
1392     o initial state input files for U and V
1393    
1394    checkpoint24
1395     o Removed some spurious "REAL"s
1396     o Updated KPP to latest version from JPL

1402    
1403    checkpoint22
1404     o Made many small changes: implicit none, format(i5), etc...
1405     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
1406

1409     o Split-up mid-level I/O routines
1410     o Updated input data for experiments 0,1,2,4 and 5
1411     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
1412    
1413    checkpoint20
1414     o Tidied up open-boundaries some more
1415     o Added non-hydrostatic code
1416     o Fixed some input data

1433       for supporting atmos. and ocean configs.
1434     o Small changes for TAMC complinace
1435     o New ultra simple test case. Barotropic box
1436       configuration "exp0".
1437    
1438    checkpoint16
1439     o Minor changes to exchange routines to support
1440       accumulation in reverse mode. Adjoint of an
1441       assignment is an addition.
1442     o Changes to support compilation by TAMC (LR(1)
1443       syntax) and by g77 under Linux ( 72 character
1444       limit ).
1445    
1446    checkpoint15
1447     Rewrote exchange routines to allow
1448     o General tile <-> tile connectivity.
1449     o TAMC reverse mode flag ( is this really needed? )
1450     o Variable width overlap and exchange region widths.
1451     o Hooks for sharing data via DMA, Arctic, Memory Channel,
1452       shmput/shmget, VIA, SYSV shmem and every other cool
1453       communication method.
1454    
1455    checkpoint14
1456     Consistent isomorphism chages made. These allow dynamical core
1457     to support both pressure and meters as a vertical coordinate.
1458    
1459    checkpoint13
1460     Release which corrects global_max problem and a couple
1461     of KGM time-averaging diagnostic errors. Also contains
1462     a double-gyre experiment setup as well as the baseline
1463     4 degree global template. The double gyre template is
1464     organised to allow it to be applied automatically to
1465     the baseline configuration.
1466    
1467    branch-point-rdot
1468     A few tidy-ups have been made bt the real point of this
1469     check-point (excuse the pun) is to allow a branch to be
1470     made for the purposes of adding the rDot alterations.
1471     I don't want to commit the rDot to the main-trunk until
1472     we've actually tested it...
1473    
1474    checkpoint12
1475     Tidy up and added generic genmake script (formerly
