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

86    
87    checkpoint52 = ecco_c52_e35
88    o after testing adjoints of checkpoint51u_post
89    
90    checkpoint51u_post
91    o this is the post-merge tag of the ecco-branch
92      (needs another clean checkout and re-testing)
93    o various natl_box_adjoint configs and results
94      but no input fields
95    o obcs adjoint not yet merged!
96    o adding ECCO global 1x1 and 2x2 degree configs
97    o updated/extended some store directives for seaice
98    o pkg/ecco now containes ecco-specific part of cost function
99    o top level routines the_main_loop, forward_step
100      supersede those in model/src/
101      previous input data.cost now in data.ecco
102      (new namelist ecco_cost_nml)
103    o in ctrl/ cleaned some cross-dependencies and updated CPP options
104    
105    checkpoint51t_post
106    o this is the pre-merge tag of the ecco-branch
107    
108    checkpoint51s_post
109    o cleanup: removed various obsolete #define-s
110    o pkg/grdchk
111      - renamed 'ph-grd 3' to 'grad-res'
112      - merged from ecco-branch
113        (remaining bug fixes for obcs gradient checks)
114      - additional high-precision output for testreport
115        (grep for 'precision_grdchk_result')
116    
117    checkpoint51r_post
118    o cleaned up or removed CPP_OPTIONS.h files
119    o updated results for some of the tests to reflect the new
120      optfiles (-ieee: -O0 instead of -O3)
121    
122    checkpoint51q_post
123    o cd_code:
124      - moved cd_scheme.F -> cd_code_scheme.F
125      - separate read_checkpoint from cd_code_ini_vars.F
126      - separated cd_code part from write_checkpoint
127      - updated AD_SOURCE, generated .flow
128      - added CD_CODE_VARS.h to the_main_loop
129      - Moving cd_code specific store dir.s to pkg/cd_code
130    o ctrl package totally restructured
131      - pack/unpack now optional and decoupled from
132        xx_/adxx_ I/O
133      - ctrl_pack/unpack cleaned
134        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
135      - confined inclusion of AD_CONFIG.h to where necessary.
136    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
137    
138    checkpoint51p_post
139    o create initial cd_code package
140      - WARNING: the initialization of fields within packages
141        is broken because INI_FIELDS (where READ_CHECKPOINT is
142        called) is called *before* PACKAGES_INIT_VARIABLES.
143        This seems to be backwards since
144        1) its important to initially zero the entire field including
145           the "halo" region
146        2) zeroing needs to be done *before* reading pickup info
147           and the pickup call might or might not happen in any
148           particular run
149      - this needs an overhaul for R2
150    o cleanup verification/*/code/GMREDI_OPTIONS.h
151    o cleanup testreport
152

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

371    
372    checkpoint50f_post
373    o exf totally restructured
374      - replaced all exf_set_ routines by one generic exf_set_gen.F

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

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

968    o new ctrl package
969      - adopted from ECCO environment to enable optimization
970      - added Eliassen Palm fluxes to controls
971    o added Eliassen Palm flux controls to gradient check package

973      - Compatible with new ctrl package
974      - added Eliassen Palm cost hooks
975      - modif's of existing cost functions
976    o Adjoint-related bug fixes in kpp:
977      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
978      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
979    o autodiff package
980      - flow directives:
981        + new for S/R do_the_model_io
982        + enhanced for S/R checkpoint
983        + new gmredi.flow

990    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
991    o incorporated hooks for sponge layer code (external_forcing.F)
992    
993    checkpoint45d_post
994    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
995    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
996      (affects plume_on_slope "cg2d" output)
997    o add new parameter deltaTfreesurf for free-surface time stepping
998    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
999    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1000    o change phiMin in exp1 (to agree with documentation)
1001    o add new flags:
1002     - T,S forcing inside/outside Adams-Bashforth
1003     - turn off temp,salt advection and/or forcing
1004     - for each tracer, define internal flag for multiDimAdvection & A-B
1005    o monitor: change definition of KE to check conservation of Energy
1006    
1007    checkpoint45c_post
1008    o Removed f90 comments ("!")
1009    o Modified initialisations to enable exf package for MITgcm

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

1045    o modified carbon verif.
1046    
1047    checkpoint44h_pre
1048    o vertical grid option: allow to put the Interface at the middle between
1049      2 cell-centers ; replace delZ in pkg/kpp by drF.
1050    o GM Advective form: Tracers are advected using the residual transport (=
1051      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1052    
1053    checkpoint44g_post
1054    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1055      results) ; ifdef missing in thermodynamics.F
1056    
1057    checkpoint44f_pre,checkpoint44f_post
1058    o added PTRACERS package
1059      This allows an arbitrary number of passive tracers to be integrated
1060      forward simultaneously with the dynamicaly model.
1061      + Implemented so far:
1062        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1063        - I/O and checkpointing
1064        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1065      + Not implemented so far:
1066        - KPP
1067        - OBCS
1068      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1069        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1070        line in data.pkg.
1071      + This package is disabled by default since it increases storage.
1072    
1073    
1074    o testscript: added -cleanup option
1075    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1076                 b) enable to filter 2D fields.
1077    
1078    checkpoint44e_pre,post
1079    o re-wrote convective adjustment to use pre-calculated weights
1080      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1081      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1082      Original calls to convect() still in place.
1083    
1084    chkpt44d_pre,post
1085    o added missing EXCLUDE_MONITOR flags
1086    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1087      (incompatible typ in MIN/MAX expressions caused problems
1088      on IBM SP3)
1089    o in genmake added variable MAKEDEPEND
1090      plus resetting for case SunOS
1091    o added timer_stats.c routine for IBM SP3
1092    o removed variables in dynamics
1093    !!! I forgot to create tag chkpt44d_pre !!!
1094    !!! But chkpt44d_pre = chkpt44c_post    !!!
1095    
1096    o real fresh water flux implemented with non-linear free-surface.
1097    
1098    chkpt44c_pre,post
1099    o few fix (mask in shap_s2, EmPmR in external_field_load,
1100      USE_NATURAL_BCS in solve_for_P);
1101    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1102    
1103    checkpoint44b_pre/_post
1104    o merge of relevant stuff from the ecco-branch:
1105      - genmake: removed $S64 overwrite for case SunOS
1106      - pkg/exf: update and corrections for field swapping and obcs
1107      - pkg/ecco: parameter lists for the_model_main, the_main_loop
1108                  harmonized between ECCO and MITgcm
1109      - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
1110                      updated checkpointing_lev... lists for obcs
1111      - model/src: minor changes in forward_step, plot_field
1112                   added directive for divided adjoint in the_main_loop
1113      - pkg/mdsio: added mdsio_gl_slice
1114    
1115    o check parameters & config (chkpt44a_pre,post)
1116    o OBC and NonLin_FrSurf.
1117    
1118    checkpoint44
1119    o fix bug in mom_vi_del2uv
1120    o select when filters are applied ; add options to zonal_filter (data.zonfilt)

1130    o some final mods for gradient check, adjoint,...
1131    
1132    checkpoint42
1133      Fixed AD-related problems:
1134    o Store directives up-to-date with re-arranged Adams-Bashforth
1135      (mainly thermodynamics.F)
1136    o New store directives for multi-dim. advection schemes
1137      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1138      * new common block and key passkey
1139      (mainly gad_advection.F)
1140    o Modified store directives for split of dynamics/thermodynamics
1141      for the case ALLOW_KPP
1142    o Cleaned argument list for timestep_tracer.F
1143    
1144    checkpoint41
1145    o re-formatted/added comments in prologues of key subroutines
1146      to work with protex
1147    
1148    checkpoint40
1149    o moved calc_gs, calc_gt and calc_tr1 back to model/src
1150    o added FLT (floats) package from Arne along with demo. experiment
1151    o re-arranged Adams-Bashforth scheme for tracers to allow easier
1152      implementation of forward-in-time forcing terms
1153    o more mods for non-linear free-surface including new variable
1154    o modified multi-dim method to work on cube
1155    o bug fix in KPP (from DM)
1156    
1157    checkpoint40pre9
1158    o added DST advection schemes
1159    o fix MPI bug on SGI's
1160    o modifications for non-linear free-surface

1162    o added tension/strain form of stress tensor
1163    o changes to commenting of arguments for TAF/TAMC
1164    o added/updated many matlab scripts
1165    o added multi-dimensional advection method for tracers
1166      
1167    checkpoint40pre8
1168    o new package rw/
1169      Added method for dumping intermediate local arrays:
1170      mdsio_writetile - same as mdsio_writefield except works from inside
1171                        bi,bj loop
1172      mdsio_writelocal - same as mdsio_writetile except works for local
1173                         arrays
1174      write_local_r? - higher-level wrapper for mdsio_writelocal
1175      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1176      Example given at end of mom_vecinv.F that dumps some local arrays.
1177    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1178      control flux-form versus vector invariant code.
1179      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1180      or genmake -DISABLE ...
1181    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1182      (additional storing is now needed for case vecinv;
1183      currently nothing implemented to switch this storing off
1184      in case fluxform is used since no CPP flag available).
1185    
1186    checkpoint40pre7
1187    o bug fix in dynamics.F
1188      calc_viscosity called before k=1,Nr loop.
1189    o added some #ifdef's ALLOW_PASSIVE_TRACER
1190    o cleaned initialisations in ctrl_map_ini
1191      related to TAF
1192    
1193    checkpoint40pre6
1194    o split dynamics into thermodynamics & dynamics
1195    o corresponding split of calc_diffusivity into
1196      calc_diffusivity, calc_viscosity
1197      (kpp_calc_diff, kpp_calc_visc).
1198    o Added diffkr, kapgm to control variables
1199    o bug fix in gmredi_slope_limit for ldd97
1200    
1201    checkpoint40pre5
1202    o proper initialization of Adams-Bashforth time stepping
1203      + uses forward step for very first step of model (iter=0)
1204    o re-generated *all* output since almost all output is modified by this
1205      change (sorry but we've been putting this one off for about 2 years)
1206      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1207        *not* regenerated since they are already out of date and I don't
1208        want to create the impression that they are suddenly working.
1209    o removed KAP stuff for DEC's
1210    o modified/added many .cvsignore files in */code and */input
1211    o added new expt "solid-body.cs-32x32x1"
1212      + this uses an alternative form of ini_curvilinear_grid.F which
1213        is not necessarily any better than the current one...
1214    
1215    checkpoint40pre4
1216    o added re-initialisations of utrans,vtrans,rtrans in
1217      calc_common_factors which are crucial for TAF.
1218    o extended iMin,jMin range for calc_common_factors,
1219      calc_diffusivity
1220    o added option ALLOW_PASSIVE_TRACER
1221    o a few minor updates and fixes
1222    
1223    checkpoint40pre3
1224    o created calc_gtr1.F for gad package
1225    o split the_main_loop and re-introduced forward_step
1226    o some recomputations of nIter0 for TAMC
1227    
1228    checkpoint40pre2
1229    o Updated to latest branch of AJA, JMC
1230    o Added gradient check package
1231    o Added routines for passive tracer handling
1232    o Added carbon sequestration sensitivity experiment
1233    
1234    checkpoint39
1235     o Modifications and fixes to support TAMC
1236       (mainly missing or wrong directives)
1237     o Corrected common blocks when fooling TAMC to produce adjoint I/O
1238       in addummy_in_stepping
1239     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1240     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1241     o Included following packages:
1242       cal: calendar
1243       exf: external forcing
1244       ecco: essential routines to control use of cal, exf
1245             (NB: this is not the full ECCO environment)
1246     o disabled some packages by default in genmake
1247    
1248    checkpoint38
1249     o see notes_c37_adj.txt
1250     o corrected wrong layer index in external_forcing_t
1251     o replaced the_main_loop/forward_step by the_main_loop
1252     o removed forceoutput from write_state
1253       (replaced criteria for initial/final state)
1254     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1255    
1256    checkpoint37
1257     o mdsio.F routine split and packaged in pkg/mdsio
1258       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1259        used unless genmake -disable=mdsio)
1260     o allow a more precise surface-geopotential gradient for the atmosphere
1261       taking into account the change in space of Alpha (=1/rho) at the surface.
1262     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1263       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1264     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1265       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1266       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1267     o Time-Average diagnostics defined as a pseudo package "timeave".
1268     o pickup files : old pickup (before c35) did not work with new code (c35
1269       and after) unless activating 2 commented lines in initialise-varia.
1270     o Non-Hydrostatic pickup file Pb fixed.
1271     o bug with Rigid-lid version (since c35) fixed.  
1272    
1273    checkpoint36
1274     o implement Crank-Nickelson barotropic time-stepping
1275     o recover Time-Average diagnostics
1276     o fix Pb in checkpoint (PR#19)
1277     o AIM become a standard package ; clean unused CPP_kees
1278    
1279    checkpoint35
1280     o subtantial rewrite of dynamics.f
1281     o allows staggered time-stepping
1282     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
1283     o added bottom drag (linear + quadratic)
1284    
1285    checkpoint34
1286     o Modified exchange routines for correct reverse simulation.
1287     o Added verification output to comply with bug fix in impldiff.F
1288       as of c33 (exp2, natl_box).
1289     o Corrected store directives in dynamics.F
1290     o Corrected array boundaries in impldiff.F
1291     o Corrected array dimensions in gmredi.
1292       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
1293     o Added routine GLOBAL_SUM_INT to global_sum.F
1294     o Added mdsio_gl.F for ECCO purposes.
1295    
1296    checkpoint33
1297     o Fixed bug in lower BC in impldiff.F
1298     o Fixed confusion about units of forcing arrays in FFIELDS.h
1299       namely Fu,Fv,Qnet,Qsw,EmPmR:
1300       - Removed verification/natl_box/code/external_fields_scale.F
1301         (did not differ from that in model/src)
1302       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
1303         (see FFIELDS.h for description)
1304       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
1305         kpp_calc.F and kpp_transport_t.F
1306       - Removed model/src/external_fields_scale.F and calls to it
1307       - verification/natl_box uses flux data with "atmospheric" sign so
1308         a special version of external_fields_load.F is used to
1309         change the data as it's read in. This way, the arrays
1310         have the right units and signs at all times tha a user could
1311         possibly use them.
1312     o Corrected genmake to delete a temporary file during configuration
1313    
1314    checkpoint32
1315     o Scaling of forcing fields moved from external_forcing.F to
1316       external_fields_scale.F, called directly after loading fields.
1317     o Surface relaxation terms added to surface tendency fields in
1318       extra subroutine.
1319     o impldiff.F changed to avoid storing by TAMC of huge intermediate
1320       fields.
1321     o Changes in GMRedi to comply with packaging structure.
1322     o Modifications and bug fixes in KPP package.
1323     o Verification experiment for KPP added (verification/nat_box/)
1324    
1325    checkpoint31
1326     o Packages interface brought in line with defined standard
1327       -> new routines packages_...F
1328       -> changes in initialise_fixed.F, initialise_varia.F
1329       -> enables initialisation interface for ECCO package
1330     o Rescaling of external forcing fields immediately after read
1331       (removed from external_forcing.F)
1332       -> new: surface_fields_scale.F
1333       -> affects ini_foorcing.F, external_fields_load.F
1334     o Computation of surface tendencies before tendency updates.
1335       -> new: external_forcing_surf.F
1336     o Change of variable names useGMRedi, useKPP, useECCO
1337     o Further changes in dynamics.F, impldiff.F for TAMC
1338     o Tested for experiments 0, 2, 4.
1339       - not yet tested for GMRedi.
1340       - not yet tested for KPP.
1341    
1342    checkpoint30
1343     o Updates for OBCs
1344     o New experiment for test OBCs (internal_wave)
1345     o New output.txt in verification/exp4/results/
1346     o Updates for KPP: calculation of viscosity corrected, new variables
1347       kpp_dumpFreq and kpp_taveFreq
1348     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
1349       and entry for T90 in genmake
1350    
1351    checkpoint29
1352     o packaged KPP and GM/Redi
1353    
1354    checkpoint28
1355     o Corrected initialization of hFacMin for difference vertical coordinates
1356     o Modified calculation of partial cell thickness to more robust algorithm
1357     o config_summary.F: replaced write_1D_... by write_0D_...
1358       read_write.F: added subroutines write_0D_...
1359     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
1360       included some initialisations required for TAMC.
1361     o routine calc_isoslopes: modified sqrt computation to make it
1362       differentiable for zero argument.
1363     o routines dynamics, impldiff:
1364       included store directives and tape key computations required for TAMC.
1365     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
1366    
1367    checkpoint27
1368     o fixed calc_isoslopes() to so that cancellation of terms in tensor
1369       formulation works properly with variable resolution.
1370     o restructured the calling tree between the_model_main() and dynamics()
1371     o split initialise() into initialise_fixed() and initialise_varia()
1372     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
1373       in new routine ini_psurf()
1374    
1375    checkpoint26
1376     o moved some #ifdef in optional routines to encompass everything
1377       except the argument declarations. This was using up some memory.
1378     o fixed macros like _ADT to work with both versions of Linux cpp
1379     o cleaned up some unused and uninitialized variables
1380       (helps when debugging with strict compile options)
1381     o split up CPP_EEOPTIONS.h into options and macros
1382       (macros are now in eesupp/inc/CPP_EEMACROS.h)
1383     o patch for 2 processor JAM mode
1384    
1385    checkpoint25
1386     o updates for OBCs and NH
1387     o dramatically reduced memory usage
1388     o added "JAM" routines for use on Artic network

1390     o added a diagnostic of convective index
1391     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
1392       (this is was partly for OBCs and NH but also in anticipation of
1393        an explicit free-surface option)
1394     o initial state input files for U and V
1395    
1396    checkpoint24
1397     o Removed some spurious "REAL"s

1405    checkpoint22
1406     o Made many small changes: implicit none, format(i5), etc...
1407     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
1408

1411     o Split-up mid-level I/O routines
1412     o Updated input data for experiments 0,1,2,4 and 5
1413     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
1414    
1415    checkpoint20
1416     o Tidied up open-boundaries some more
1417     o Added non-hydrostatic code
1418     o Fixed some input data

1435       for supporting atmos. and ocean configs.
1436     o Small changes for TAMC complinace
1437     o New ultra simple test case. Barotropic box
1438       configuration "exp0".
1439    
1440    checkpoint16
1441     o Minor changes to exchange routines to support
1442       accumulation in reverse mode. Adjoint of an
1443       assignment is an addition.
1444     o Changes to support compilation by TAMC (LR(1)
1445       syntax) and by g77 under Linux ( 72 character
1446       limit ).
1447    
1448    checkpoint15
1449     Rewrote exchange routines to allow
1450     o General tile <-> tile connectivity.
1451     o TAMC reverse mode flag ( is this really needed? )
1452     o Variable width overlap and exchange region widths.
1453     o Hooks for sharing data via DMA, Arctic, Memory Channel,
1454       shmput/shmget, VIA, SYSV shmem and every other cool
1455       communication method.
1456    
1457    checkpoint14
1458     Consistent isomorphism chages made. These allow dynamical core
1459     to support both pressure and meters as a vertical coordinate.
1460    
1461    checkpoint13
1462     Release which corrects global_max problem and a couple
1463     of KGM time-averaging diagnostic errors. Also contains
1464     a double-gyre experiment setup as well as the baseline
1465     4 degree global template. The double gyre template is
1466     organised to allow it to be applied automatically to
1467     the baseline configuration.
1468    
1469    branch-point-rdot
1470     A few tidy-ups have been made bt the real point of this
1471     check-point (excuse the pun) is to allow a branch to be
1472     made for the purposes of adding the rDot alterations.
1473     I don't want to commit the rDot to the main-trunk until
1474     we've actually tested it...
1475    
1476    checkpoint12
1477     Tidy up and added generic genmake script (formerly
1478     configure script).
