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

67      but no warning issued by TAF
68    
69    checkpoint52a_pre
70    o some bug fixes for #undef REAL4_IS_SLOW
71    
72    checkpoint52 = ecco_c52_e35
73    o after testing adjoints of checkpoint51u_post
74    
75    checkpoint51u_post
76    o this is the post-merge tag of the ecco-branch
77      (needs another clean checkout and re-testing)
78    o various natl_box_adjoint configs and results
79      but no input fields
80    o obcs adjoint not yet merged!
81    o adding ECCO global 1x1 and 2x2 degree configs
82    o updated/extended some store directives for seaice
83    o pkg/ecco now containes ecco-specific part of cost function
84    o top level routines the_main_loop, forward_step
85      supersede those in model/src/
86      previous input data.cost now in data.ecco
87      (new namelist ecco_cost_nml)
88    o in ctrl/ cleaned some cross-dependencies and updated CPP options
89    
90    checkpoint51t_post
91    o this is the pre-merge tag of the ecco-branch
92    
93    checkpoint51s_post
94    o cleanup: removed various obsolete #define-s
95    o pkg/grdchk
96      - renamed 'ph-grd 3' to 'grad-res'
97      - merged from ecco-branch
98        (remaining bug fixes for obcs gradient checks)
99      - additional high-precision output for testreport
100        (grep for 'precision_grdchk_result')
101    
102    checkpoint51r_post
103    o cleaned up or removed CPP_OPTIONS.h files
104    o updated results for some of the tests to reflect the new
105      optfiles (-ieee: -O0 instead of -O3)
106    
107    checkpoint51q_post
108    o cd_code:
109      - moved cd_scheme.F -> cd_code_scheme.F
110      - separate read_checkpoint from cd_code_ini_vars.F
111      - separated cd_code part from write_checkpoint
112      - updated AD_SOURCE, generated .flow
113      - added CD_CODE_VARS.h to the_main_loop
114      - Moving cd_code specific store dir.s to pkg/cd_code
115    o ctrl package totally restructured
116      - pack/unpack now optional and decoupled from
117        xx_/adxx_ I/O
118      - ctrl_pack/unpack cleaned
119        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
120      - confined inclusion of AD_CONFIG.h to where necessary.
121    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
122    
123    checkpoint51p_post
124    o create initial cd_code package
125      - WARNING: the initialization of fields within packages
126        is broken because INI_FIELDS (where READ_CHECKPOINT is
127        called) is called *before* PACKAGES_INIT_VARIABLES.
128        This seems to be backwards since
129        1) its important to initially zero the entire field including
130           the "halo" region
131        2) zeroing needs to be done *before* reading pickup info
132           and the pickup call might or might not happen in any
133           particular run
134      - this needs an overhaul for R2
135    o cleanup verification/*/code/GMREDI_OPTIONS.h
136    o cleanup testreport

146    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
147    o bug fix in find_alpha.F for MDJWF:
148      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
149        change rho -> rho-rhoConst
150      - replace call find_rho to find_rhonum
151    o initialisation of rFlx extended to full array (required by TAF)
152      and shifted to thermodynamics
153    o removed PTRACERS.h in ptracers routine
154    o added surfacetendencyPtr to S/R parameter list pracers_forcing
155    o Correcting initialisations for fVerU, fVerV.

173         global_ocean.cs32x15, and global_with_exf)
174    o added surface flux output variables to TIMEAVE_STATVARS

261    
262    checkpoint51f_pre
263    o Added on-the-fly spatial interpolation capability
264        "USE_EXF_INTERPOLATION" to pkg/exf.
265      - This is a temporary Cartesian-grid hack until
266        the super-duper ESMF coupler becomes available.
267      - See verification/global_with_exf/README for usage example.
268      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

377     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
378       nearly a copy of kpp_transport_s
379     - there is no analogue to SurfaceTendencyS, so I have to use
380       gPtr(of the surface layer) instead
381    o add a new platform SunFire+mpi (SunFire 15000) to genmake
382    checkpoint50e_pre
383

403    o Added SEAICE_initialHEFF to pkg/seaice
404    
405    checkpoint50b_post
406    o store u*,v* in gU,V instead of in guNm1,gvNm1
407    o in order to put the momForcing out of the Adams-Bashforth:
408      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
409      to timestep.F
410    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
411    o re-generate output for highly sensitive test-exp:
412       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
413    
414    checkpoint50b_pre
415    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)

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

773    
774      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
775    o GAD:
776      - generated new common blocks to account for call of
777        same gad routines with differing traceridentities
778        (needed to modify tracerIdentity indices in GAD.h)
779      - generated separate common blocks for case useCubedSphereExchange
780        (Department of Futurology)
781      - parameter lists to gmredi_?transport: added tracerIdentity
782      - added new key indices to tamc.h
783    o external_fields_load:
784      - added this routine to TAF list
785      - needed to make some common blocks global and additional storing
786        along the same lines as exf package (checkpoint_lev?_directives.h)
787    o exf:
788      updated external forcing package
789      - bug fixes carried over from ecco-branch
790        (missing OBCS_OPTIONS.h in two routines)
791      - enable easy to use "no forcing".
792      - added exf I/O for atmospheric loading
793      - added exf I/O for runoff data
794      - transfered scaling between exf <-> MITgcm to exf namelist
795    o Adding new verification experiment global_with_exf.
796      This verification experiment is almost identical to the
797      global_ocean.90x40x15 experiment, except that it uses
798      the exf (and cal) package instead of the
799      external_fields_load routine (cf README file).
800    
801    checkpoint46m_post
802    o modified testscript to return -- when there are no lines of "%MON" output
803    o added new flag "quasiHydrostatic" for QH mode
804      and new routine quasihydrostaticterms()
805    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
806      New routine: mom_u_coriolis_nh()
807    o fixed sign of non-hydrostatic metric terms in u and v equations.
808      Depend on correct sign of gravitySign.
809    o added work.pc* to .cvsignore in aim directories using ifc
810    o introduced flag for controllin non-hydrostatic metric terms
811    o removed gravitySign from PARM04
812    o switched to g77/ifc from pgf77 in aim experiments
813    
814    checkpoint46l_post
815    o made convective adjustment work with pressure coordinates:
816     - changed the direction of k-loop in convective_adjustment.F for the
817       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
818     - adjusted the reference pressure k-index in convective_adjustment.F
819     - adjusted the convection condition in convect.F (in analogy to
820       calc_ivdc.F)
821     - convective_adjustment no longer computes anything on the halos
822     - removed the warnings about negative salinity from find_rho.F and
823       find_alpha.F; instead the new routine look_for_neg_salinity, called
824       at the beginning of find_rho, find_alpha, and find_beta, does a
825       check of the entire slice, if CPP-option
826       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
827    checkpoint46l_pre
828    
829    checkpoint46k_post
830    o fixed the verification/global_ocean.90x40x15 experiment:
831     - new bathymetry (the world according to A., JMC, and M.)
832     - new initial fields and forcing fields (*.bin files)
833     - new POLY3.COEFFS (for the next release one should switch to a full
834       equation of state: JMD95P or MDJWF)
835     - fixed several errors and redundancies in the data file
836     - experiment uses looped cells
837     - added matlab directory with diagnostic scripts for plotting of output
838    
839    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
840     - read AIM physics parameters from a file (data.aimphys)
841     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
842    
843    checkpoint46j_post
844    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
845    o move wVel computation at the end of the time step, in S/R integr_continuity
846    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
847    o update timeave pkg for wVel diagnostic.
848    checkpoint46j_pre
849    
850    checkpoint46i_post
851    o Clean up AIM package (and keep the results unchanged):
852      include CPP_OPTION and use IMPLICT NONE in all routines ;
853      declare all the variables _RL ; use _d 0 for all numerical constants.
854      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
855    
856    checkpoint46h_post
857    o cleaned up the use of rhoNil and rhoConst.
858      - rhoNil should only appear in the LINEAR equation of state, everywhere
859        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
860        and the dynamical equations are all divided by rhoConst
861    o introduced new parameter rhoConstFresh, a reference density of fresh
862      water, to remove the fresh water flux's dependence on rhoNil. The default
863      value is 999.8 kg/m^3
864    o cleanup up external_forcing.F and external_forcing_surf.F
865      - can now be used by both OCEANIC and OCEANICP
866    checkpoint46h_pre
867    
868     Added code to convert surface volume flux (fresh water) into
869     a mass flux when using P coordinates in the ocean (OCEANICP).
870     Note: It assumes you have set rho0=rhoConst=density of fresh water.
871    
872    checkpoint46g_post
873    o Include a new diagnostic variable phiHydLow for the ocean model
874      - in z-coordinates, it is the bottom pressure anomaly
875      - in p-coordinates, it is the sea surface elevation
876      - in both cases, these variable have global drift, reflecting the mass
877        drift in z-coordinates and the volume drift in p-coordinates
878      - included time averaging for phiHydLow, be aware of the drift!
879    o depth-dependent computation of Bo_surf for pressure coordinates
880      in the ocean (buoyancyRelation='OCEANICP')
881      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
882        Theta, Salinity, and Pressure in the parameter list. This routine is
883        presently contained in find_rho.F. This routine does not give the
884        correct density for 'POLY3', which would be a z-dependent reference
885        density.
886    o cleaned up find_rho
887      - removed obsolete 'eqn' from the parameter list.
888    o added two new verification experiments: gop and goz
889      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
890    checkpoint46g_pre
891    
892    checkpoint46f_post
893    o Enable tangent linear (forward mode) gradient checks:
894      - extended active file handling to g_... files
895      - added TANGENT_SIMULATION to theSimulationMode
896      - extended grdchk package accordingly
897    o added tangent linear setup in verification/carbon/code_ftl
898    o added adjoint setup in verification/front_relax/code_ad
899    
900    checkpoint46e_post
901    o Added new equation of state -> MDJWF
902      - EOS of McDougall et al., 2002, JAOT, submitted
903      - caveat: the equation of state is only valid for a smaller (more
904        realistic?) range of values than JMD95P/Z and UNESCO
905      - added masks to the calculation of pressure in store_pressure
906      - added more check values for density in check_eos (ini_eos.F), some of
907        the old check values are out of the range of the MDJWF-eos, so don't
908        expect perfect matches for those
909    checkpoint46e_pre
910    
911    checkpoint46d_post
912    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
913      'OCEANICP', also initialised field pressure correctly in ini_eos in the
914      case of pressure coordinates. eosType='JMD95Z' in
915      combination with buoyancyRelation='OCEANICP' now causes an error.
916    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
917      in find_alpha/beta.
918    checkpoint46d_pre
919    
920    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
921      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
922    
923    checkpoint46c_post
924    o Changes necessary for ocean in p-coordinates
925     -  Added new buoyancy relation = 'OCEANICP'
926     -  Added new parameters = gravitySign (this used to be contained inside
927        the factor dRdZ which I added when we first switched to R coordinates).
928     X GM/Redi is not compatible (yet)
929     X bottom drag and no-slip need to be debugged.
930    checkpoint46c_pre
931    
932    checkpoint46b_post
933    o Added new equation of state -> JMD95Z and JMD95P
934      - EOS of Jackett and McDougall, 1995, JAOT
935      - moved all EOS parameters into EOS.h
936      - new routines ini_eos.F, store_pressure.F
937    o Added UNESCO EOS, but not recommended because it requires
938      in-situ temperature (see JMD95)
939    o Modified formatting for knudsen2.f in utils/knudsen2 and added
940      unesco.f to be used with POLY3
941    checkpoint46b_pre
942    
943    checkpoint46a_post
944    o Added (atmospheric) pressure loading
945      - new field in FFIELDS.h, etc...
946      - new cpp flag ATMOSPHERIC_LOADING
947    o Changed hFacC to _hFacC in calc_phi_hyd.F
948    o Added SHORTWAVE_HEATING to some files for consistency
949    checkpoint46a_pre
950    
951    checkpoint46

962      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
963      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
964    o autodiff package
965      - flow directives:

977    
978    checkpoint45d_post
979    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
980    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
981      (affects plume_on_slope "cg2d" output)
982    o add new parameter deltaTfreesurf for free-surface time stepping
983    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
984    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
985    o change phiMin in exp1 (to agree with documentation)
986    o add new flags:
987     - T,S forcing inside/outside Adams-Bashforth
988     - turn off temp,salt advection and/or forcing
989     - for each tracer, define internal flag for multiDimAdvection & A-B
990    o monitor: change definition of KE to check conservation of Energy
991    
992    checkpoint45c_post
993    o Removed f90 comments ("!")

1003    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1004      to configure barotropic setup (Martin Losch)
1005    o moved some initialisations within bi,bj loop in dynamics
1006      (TAF flow dependency)
1007    o in initialise_varia, moved call packages_init_variables
1008      before convective_adjustment_init
1009      (corresponding adjustment of TAF tape initialisation).
1010    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1011    
1012    checkpoint45a_post
1013    o compute Rho over the whole domain (extend iMin,jMin indices)
1014    o specific exchange for X-slice domain (case Ny=1)
1015    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1016    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1017    
1018    checkpoint44h_post = checkpoint45
1019    o Fix to restore differentiability:
1020      place at which packages_init_variables is called in
1021      initialise_varia is crucial for reverse control flow.
1022    o modifications in GMRedi to enable stable adjoint
1023      (corresponding modif's in thermodynamics, dynamics)
1024    o added missing hook for sponge layer code in external_forcing

1030    o modified carbon verif.
1031    
1032    checkpoint44h_pre
1033    o vertical grid option: allow to put the Interface at the middle between
1034      2 cell-centers ; replace delZ in pkg/kpp by drF.
1035    o GM Advective form: Tracers are advected using the residual transport (=
1036      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1037    
1038    checkpoint44g_post
1039    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1040      results) ; ifdef missing in thermodynamics.F
1041    
1042    checkpoint44f_pre,checkpoint44f_post
1043    o added PTRACERS package
1044      This allows an arbitrary number of passive tracers to be integrated
1045      forward simultaneously with the dynamicaly model.
1046      + Implemented so far:
1047        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1048        - I/O and checkpointing
1049        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1050      + Not implemented so far:
1051        - KPP
1052        - OBCS
1053      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1054        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1055        line in data.pkg.
1056      + This package is disabled by default since it increases storage.
1057    
1058    
1059    o testscript: added -cleanup option
1060    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter

1062    
1063    checkpoint44e_pre,post
1064    o re-wrote convective adjustment to use pre-calculated weights
1065      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1066      Adds:    model/src/convective_weights.F, convectively_mixtracer.F

1070    o added missing EXCLUDE_MONITOR flags
1071    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi

1073      on IBM SP3)
1074    o in genmake added variable MAKEDEPEND
1075      plus resetting for case SunOS
1076    o added timer_stats.c routine for IBM SP3
1077    o removed variables in dynamics
1078    !!! I forgot to create tag chkpt44d_pre !!!
1079    !!! But chkpt44d_pre = chkpt44c_post    !!!
1080    
1081    o real fresh water flux implemented with non-linear free-surface.
1082    
1083    chkpt44c_pre,post
1084    o few fix (mask in shap_s2, EmPmR in external_field_load,
1085      USE_NATURAL_BCS in solve_for_P);
1086    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1087    
1088    checkpoint44b_pre/_post
1089    o merge of relevant stuff from the ecco-branch:
1090      - genmake: removed $S64 overwrite for case SunOS
1091      - pkg/exf: update and corrections for field swapping and obcs

1102    
1103    checkpoint44
1104    o fix bug in mom_vi_del2uv
1105    o select when filters are applied ; add options to zonal_filter (data.zonfilt)

1116    
1117    checkpoint42
1118      Fixed AD-related problems:
1119    o Store directives up-to-date with re-arranged Adams-Bashforth
1120      (mainly thermodynamics.F)
1121    o New store directives for multi-dim. advection schemes
1122      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1123      * new common block and key passkey
1124      (mainly gad_advection.F)
1125    o Modified store directives for split of dynamics/thermodynamics
1126      for the case ALLOW_KPP
1127    o Cleaned argument list for timestep_tracer.F
1128    
1129    checkpoint41
1130    o re-formatted/added comments in prologues of key subroutines
1131      to work with protex
1132    
1133    checkpoint40
1134    o moved calc_gs, calc_gt and calc_tr1 back to model/src
1135    o added FLT (floats) package from Arne along with demo. experiment
1136    o re-arranged Adams-Bashforth scheme for tracers to allow easier
1137      implementation of forward-in-time forcing terms
1138    o more mods for non-linear free-surface including new variable
1139    o modified multi-dim method to work on cube
1140    o bug fix in KPP (from DM)

1151      
1152    checkpoint40pre8
1153    o new package rw/
1154      Added method for dumping intermediate local arrays:
1155      mdsio_writetile - same as mdsio_writefield except works from inside
1156                        bi,bj loop
1157      mdsio_writelocal - same as mdsio_writetile except works for local
1158                         arrays
1159      write_local_r? - higher-level wrapper for mdsio_writelocal
1160      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1161      Example given at end of mom_vecinv.F that dumps some local arrays.
1162    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1163      control flux-form versus vector invariant code.
1164      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1165      or genmake -DISABLE ...
1166    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1167      (additional storing is now needed for case vecinv;
1168      currently nothing implemented to switch this storing off
1169      in case fluxform is used since no CPP flag available).
1170    
1171    checkpoint40pre7
1172    o bug fix in dynamics.F
1173      calc_viscosity called before k=1,Nr loop.

1180    o corresponding split of calc_diffusivity into
1181      calc_diffusivity, calc_viscosity
1182      (kpp_calc_diff, kpp_calc_visc).
1183    o Added diffkr, kapgm to control variables
1184    o bug fix in gmredi_slope_limit for ldd97
1185    
1186    checkpoint40pre5
1187    o proper initialization of Adams-Bashforth time stepping
1188      + uses forward step for very first step of model (iter=0)
1189    o re-generated *all* output since almost all output is modified by this
1190      change (sorry but we've been putting this one off for about 2 years)
1191      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1192        *not* regenerated since they are already out of date and I don't
1193        want to create the impression that they are suddenly working.
1194    o removed KAP stuff for DEC's
1195    o modified/added many .cvsignore files in */code and */input
1196    o added new expt "solid-body.cs-32x32x1"
1197      + this uses an alternative form of ini_curvilinear_grid.F which
1198        is not necessarily any better than the current one...
1199    
1200    checkpoint40pre4
1201    o added re-initialisations of utrans,vtrans,rtrans in
1202      calc_common_factors which are crucial for TAF.
1203    o extended iMin,jMin range for calc_common_factors,
1204      calc_diffusivity

1206    o a few minor updates and fixes
1207    
1208    checkpoint40pre3
1209    o created calc_gtr1.F for gad package
1210    o split the_main_loop and re-introduced forward_step
1211    o some recomputations of nIter0 for TAMC
1212    
1213    checkpoint40pre2
1214    o Updated to latest branch of AJA, JMC
1215    o Added gradient check package
1216    o Added routines for passive tracer handling
1217    o Added carbon sequestration sensitivity experiment
1218    
1219    checkpoint39

1222     o Corrected common blocks when fooling TAMC to produce adjoint I/O
1223       in addummy_in_stepping
1224     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1225     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1226     o Included following packages:
1227       cal: calendar
1228       exf: external forcing
1229       ecco: essential routines to control use of cal, exf
1230             (NB: this is not the full ECCO environment)
1231     o disabled some packages by default in genmake
1232    
1233    checkpoint38
1234     o see notes_c37_adj.txt
1235     o corrected wrong layer index in external_forcing_t
1236     o replaced the_main_loop/forward_step by the_main_loop
1237     o removed forceoutput from write_state
1238       (replaced criteria for initial/final state)
1239     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1240    
1241    checkpoint37
1242     o mdsio.F routine split and packaged in pkg/mdsio
1243       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1244        used unless genmake -disable=mdsio)
1245     o allow a more precise surface-geopotential gradient for the atmosphere
1246       taking into account the change in space of Alpha (=1/rho) at the surface.
1247     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1248       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1249     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1250       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1251       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1252     o Time-Average diagnostics defined as a pseudo package "timeave".
1253     o pickup files : old pickup (before c35) did not work with new code (c35
1254       and after) unless activating 2 commented lines in initialise-varia.
1255     o Non-Hydrostatic pickup file Pb fixed.
1256     o bug with Rigid-lid version (since c35) fixed.  
1257    
1258    checkpoint36
1259     o implement Crank-Nickelson barotropic time-stepping
1260     o recover Time-Average diagnostics
1261     o fix Pb in checkpoint (PR#19)
1262     o AIM become a standard package ; clean unused CPP_kees
1263    
1264    checkpoint35
1265     o subtantial rewrite of dynamics.f
1266     o allows staggered time-stepping
1267     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
1268     o added bottom drag (linear + quadratic)
1269    
1270    checkpoint34
1271     o Modified exchange routines for correct reverse simulation.
1272     o Added verification output to comply with bug fix in impldiff.F
1273       as of c33 (exp2, natl_box).

1275     o Corrected array boundaries in impldiff.F
1276     o Corrected array dimensions in gmredi.

1279     o Added mdsio_gl.F for ECCO purposes.
1280    
1281    checkpoint33
1282     o Fixed bug in lower BC in impldiff.F
1283     o Fixed confusion about units of forcing arrays in FFIELDS.h
1284       namely Fu,Fv,Qnet,Qsw,EmPmR:
1285       - Removed verification/natl_box/code/external_fields_scale.F
1286         (did not differ from that in model/src)
1287       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
1288         (see FFIELDS.h for description)
1289       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
1290         kpp_calc.F and kpp_transport_t.F
1291       - Removed model/src/external_fields_scale.F and calls to it
1292       - verification/natl_box uses flux data with "atmospheric" sign so
1293         a special version of external_fields_load.F is used to
1294         change the data as it's read in. This way, the arrays
1295         have the right units and signs at all times tha a user could
1296         possibly use them.
1297     o Corrected genmake to delete a temporary file during configuration
1298    
1299    checkpoint32

1313       -> changes in initialise_fixed.F, initialise_varia.F
1314       -> enables initialisation interface for ECCO package
1315     o Rescaling of external forcing fields immediately after read
1316       (removed from external_forcing.F)
1317       -> new: surface_fields_scale.F
1318       -> affects ini_foorcing.F, external_fields_load.F
1319     o Computation of surface tendencies before tendency updates.
1320       -> new: external_forcing_surf.F
1321     o Change of variable names useGMRedi, useKPP, useECCO
1322     o Further changes in dynamics.F, impldiff.F for TAMC
1323     o Tested for experiments 0, 2, 4.
1324       - not yet tested for GMRedi.

1342     o config_summary.F: replaced write_1D_... by write_0D_...
1343       read_write.F: added subroutines write_0D_...
1344     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
1345       included some initialisations required for TAMC.
1346     o routine calc_isoslopes: modified sqrt computation to make it
1347       differentiable for zero argument.
1348     o routines dynamics, impldiff:
1349       included store directives and tape key computations required for TAMC.
1350     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
1351    
1352    checkpoint27
1353     o fixed calc_isoslopes() to so that cancellation of terms in tensor
1354       formulation works properly with variable resolution.

1359    
1360    checkpoint26
1361     o moved some #ifdef in optional routines to encompass everything
1362       except the argument declarations. This was using up some memory.
1363     o fixed macros like _ADT to work with both versions of Linux cpp
1364     o cleaned up some unused and uninitialized variables
1365       (helps when debugging with strict compile options)
1366     o split up CPP_EEOPTIONS.h into options and macros
1367       (macros are now in eesupp/inc/CPP_EEMACROS.h)
1368     o patch for 2 processor JAM mode
1369    
1370    checkpoint25
