4      ==============================      ==============================
5    
6    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
7    
8    checkpoint52d_pre
9    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
10    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
11    
12    checkpoint52c_post
13    o Fixing OPTIONS files for use of exf:
14      - ALLOW_ECCO not needed
15      - ECCO_CPPOPTIONS.h should not be included from
16        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
17        as has been the case in the past
18      - All cal/exf related options are currently set in
19        single header file. Should remain so until we
20        agree on a consistent new policy.
21    o Removed all CPP options for cal package.
22      cal has no more CPP options.
23    o modified STOREs in GAD_ADVECTION
24    o corrected key comp. for passkey
25    
26    checkpoint52b_post
27    o new version: "thsice" of thermodynamic sea-ice pkg:
28     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
29     - modify fluxes but do not change theta directly;
30     - light cleaning of bulk_force pkg (still needed with thsice).
31     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
32       + output_thsice.txt to test thsice & bulk_force pkgs.
33    o put back grid & coriolis monitor output.
34    checkpoint52b_pre
35    
36    o call "do_the_model_io" at the beginning (=> dump initial state)
37    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
38    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
39      (need info on NUMBER_OF_PTRACERS)
40    o missing PTRACERS headers in some routines
41    o default tamc.h in pkg/autodiff supposed to crash
42      to ensure proper customization
43    
44    checkpoint52a_post
45    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
46      - moved surfaceTendencyTice from pkg/seaice to main code
47      - subroutine FREEZE_SURFACE now limits only surface temperature
48        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
49        => new output.txt for global_ocean.cs32x15 & global_with_exf
50      - keep the old version of FREEZE for backward compatibility;
51        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
52      - corresponding modifs for TAF directives
53    o added surface flux output variables to TIMEAVE_STATVARS
54    o time-averaged output for pkg/ptracers
55    o fix problem with ECCO-related divided adjoint
56      snapshot file was missing some ad-variables,
57      but no warning issued by TAF
58    
59    checkpoint52a_pre
60    o some bug fixes for #undef REAL4_IS_SLOW
61    
62    checkpoint52 = ecco_c52_e35
63    o after testing adjoints of checkpoint51u_post
64    
65    checkpoint51u_post
66    o this is the post-merge tag of the ecco-branch
67      (needs another clean checkout and re-testing)
68    o various natl_box_adjoint configs and results
69      but no input fields
70    o obcs adjoint not yet merged!
71    o adding ECCO global 1x1 and 2x2 degree configs
72    o updated/extended some store directives for seaice
73    o pkg/ecco now containes ecco-specific part of cost function
74    o top level routines the_main_loop, forward_step
75      supersede those in model/src/
76      previous input data.cost now in data.ecco
77      (new namelist ecco_cost_nml)
78    o in ctrl/ cleaned some cross-dependencies and updated CPP options
79    
80    checkpoint51t_post
81    o this is the pre-merge tag of the ecco-branch
82    
83    checkpoint51s_post
84    o cleanup: removed various obsolete #define-s
85    o pkg/grdchk
86      - renamed 'ph-grd 3' to 'grad-res'
87      - merged from ecco-branch
88        (remaining bug fixes for obcs gradient checks)
89      - additional high-precision output for testreport
90        (grep for 'precision_grdchk_result')
91    
92    checkpoint51r_post
93    o cleaned up or removed CPP_OPTIONS.h files
94    o updated results for some of the tests to reflect the new
95      optfiles (-ieee: -O0 instead of -O3)
96    
97    checkpoint51q_post
98    o cd_code:
99      - moved cd_scheme.F -> cd_code_scheme.F
100      - separate read_checkpoint from cd_code_ini_vars.F
101      - separated cd_code part from write_checkpoint
102      - updated AD_SOURCE, generated .flow
103      - added CD_CODE_VARS.h to the_main_loop
104      - Moving cd_code specific store dir.s to pkg/cd_code
105    o ctrl package totally restructured
106      - pack/unpack now optional and decoupled from
107        xx_/adxx_ I/O
108      - ctrl_pack/unpack cleaned
109        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
110      - confined inclusion of AD_CONFIG.h to where necessary.
111    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
112    
113    checkpoint51p_post
114    o create initial cd_code package
115      - WARNING: the initialization of fields within packages
116        is broken because INI_FIELDS (where READ_CHECKPOINT is
117        called) is called *before* PACKAGES_INIT_VARIABLES.
118        This seems to be backwards since
119        1) its important to initially zero the entire field including
120           the "halo" region
121        2) zeroing needs to be done *before* reading pickup info
122           and the pickup call might or might not happen in any
123           particular run
124      - this needs an overhaul for R2
125    o cleanup verification/*/code/GMREDI_OPTIONS.h
126    o cleanup testreport
127    
128    checkpoint51o_post

134    o (more) consistent directory structure for AD-related verif.'s
135    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
136    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
137    o bug fix in find_alpha.F for MDJWF:
138      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
139        change rho -> rho-rhoConst
140      - replace call find_rho to find_rhonum
141    o initialisation of rFlx extended to full array (required by TAF)
142      and shifted to thermodynamics
143    o removed PTRACERS.h in ptracers routine
144    o added surfacetendencyPtr to S/R parameter list pracers_forcing
145    o Correcting initialisations for fVerU, fVerV.

163         global_ocean.cs32x15, and global_with_exf)
164    o added surface flux output variables to TIMEAVE_STATVARS

251    
252    checkpoint51f_pre
253    o Added on-the-fly spatial interpolation capability
254        "USE_EXF_INTERPOLATION" to pkg/exf.
255      - This is a temporary Cartesian-grid hack until
256        the super-duper ESMF coupler becomes available.
257      - See verification/global_with_exf/README for usage example.
258      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid

346    
347    checkpoint50f_post
348    o exf totally restructured
349      - replaced all exf_set_ routines by one generic exf_set_gen.F
350        and made sure it's still differentiable

367     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
368       nearly a copy of kpp_transport_s
369     - there is no analogue to SurfaceTendencyS, so I have to use
370       gPtr(of the surface layer) instead
371    o add a new platform SunFire+mpi (SunFire 15000) to genmake
372    checkpoint50e_pre
373

378      analogous to the cg2d-related output.
379    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
380      so that writing to internal file fn (with length 512) fails.
381    checkpoint50d_pre
382    
383    checkpoint50c_post

393    o Added SEAICE_initialHEFF to pkg/seaice
394    
395    checkpoint50b_post
396    o store u*,v* in gU,V instead of in guNm1,gvNm1
397    o in order to put the momForcing out of the Adams-Bashforth:
398      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
399      to timestep.F
400    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
401    o re-generate output for highly sensitive test-exp:
402       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
403    
404    checkpoint50b_pre
405    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
406    o corrected CPP option mismatch in exf_Bulk... functions for case
407      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
408    
409    checkpoint50a_post
410    o Bug fix for merging between c50 and KPP.
411      ikey was passed from thermodynamics to kpp_calc via
412      common block rather than being recomputed in kpp_calc,
413      in contradiction with new key itdkey.
414      New key ikppkey created, and tamc.h headers updated.
415    
416    checkpoint50
417    - 2nd step of merge with ecco-branch:
418      merge changes in ecco-branch back into main trunk
419    - bug fix in find_alpha
420    - more storing in gmredi_calc_tensor.F, kpp_routines.F

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

763    
764      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
765    o GAD:
766      - generated new common blocks to account for call of
767        same gad routines with differing traceridentities
768        (needed to modify tracerIdentity indices in GAD.h)
769      - generated separate common blocks for case useCubedSphereExchange
770        (Department of Futurology)
771      - parameter lists to gmredi_?transport: added tracerIdentity
772      - added new key indices to tamc.h
773    o external_fields_load:
774      - added this routine to TAF list
775      - needed to make some common blocks global and additional storing
776        along the same lines as exf package (checkpoint_lev?_directives.h)
777    o exf:
778      updated external forcing package
779      - bug fixes carried over from ecco-branch
780        (missing OBCS_OPTIONS.h in two routines)
781      - enable easy to use "no forcing".
782      - added exf I/O for atmospheric loading
783      - added exf I/O for runoff data
784      - transfered scaling between exf <-> MITgcm to exf namelist
785    o Adding new verification experiment global_with_exf.
786      This verification experiment is almost identical to the
787      global_ocean.90x40x15 experiment, except that it uses
788      the exf (and cal) package instead of the
789      external_fields_load routine (cf README file).
790    
791    checkpoint46m_post
792    o modified testscript to return -- when there are no lines of "%MON" output
793    o added new flag "quasiHydrostatic" for QH mode
794      and new routine quasihydrostaticterms()
795    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
796      New routine: mom_u_coriolis_nh()
797    o fixed sign of non-hydrostatic metric terms in u and v equations.
798      Depend on correct sign of gravitySign.
799    o added work.pc* to .cvsignore in aim directories using ifc
800    o introduced flag for controllin non-hydrostatic metric terms
801    o removed gravitySign from PARM04
802    o switched to g77/ifc from pgf77 in aim experiments
803    
804    checkpoint46l_post
805    o made convective adjustment work with pressure coordinates:
806     - changed the direction of k-loop in convective_adjustment.F for the
807       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
808     - adjusted the reference pressure k-index in convective_adjustment.F
809     - adjusted the convection condition in convect.F (in analogy to
810       calc_ivdc.F)
811     - convective_adjustment no longer computes anything on the halos
812     - removed the warnings about negative salinity from find_rho.F and
813       find_alpha.F; instead the new routine look_for_neg_salinity, called
814       at the beginning of find_rho, find_alpha, and find_beta, does a
815       check of the entire slice, if CPP-option
816       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
817    checkpoint46l_pre
818    
819    checkpoint46k_post
820    o fixed the verification/global_ocean.90x40x15 experiment:
821     - new bathymetry (the world according to A., JMC, and M.)
822     - new initial fields and forcing fields (*.bin files)
823     - new POLY3.COEFFS (for the next release one should switch to a full
824       equation of state: JMD95P or MDJWF)
825     - fixed several errors and redundancies in the data file
826     - experiment uses looped cells
827     - added matlab directory with diagnostic scripts for plotting of output
828    
829    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
830     - read AIM physics parameters from a file (data.aimphys)
831     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
832    
833    checkpoint46j_post
834    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
835    o move wVel computation at the end of the time step, in S/R integr_continuity
836    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
837    o update timeave pkg for wVel diagnostic.
838    checkpoint46j_pre
839    
840    checkpoint46i_post
841    o Clean up AIM package (and keep the results unchanged):
842      include CPP_OPTION and use IMPLICT NONE in all routines ;
843      declare all the variables _RL ; use _d 0 for all numerical constants.
844      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
845    
846    checkpoint46h_post
847    o cleaned up the use of rhoNil and rhoConst.
848      - rhoNil should only appear in the LINEAR equation of state, everywhere
849        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
850        and the dynamical equations are all divided by rhoConst
851    o introduced new parameter rhoConstFresh, a reference density of fresh
852      water, to remove the fresh water flux's dependence on rhoNil. The default
853      value is 999.8 kg/m^3
854    o cleanup up external_forcing.F and external_forcing_surf.F
855      - can now be used by both OCEANIC and OCEANICP
856    checkpoint46h_pre
857    
858     Added code to convert surface volume flux (fresh water) into
859     a mass flux when using P coordinates in the ocean (OCEANICP).
860     Note: It assumes you have set rho0=rhoConst=density of fresh water.
861    
862    checkpoint46g_post
863    o Include a new diagnostic variable phiHydLow for the ocean model
864      - in z-coordinates, it is the bottom pressure anomaly
865      - in p-coordinates, it is the sea surface elevation
866      - in both cases, these variable have global drift, reflecting the mass
867        drift in z-coordinates and the volume drift in p-coordinates
868      - included time averaging for phiHydLow, be aware of the drift!
869    o depth-dependent computation of Bo_surf for pressure coordinates
870      in the ocean (buoyancyRelation='OCEANICP')
871      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
872        Theta, Salinity, and Pressure in the parameter list. This routine is
873        presently contained in find_rho.F. This routine does not give the
874        correct density for 'POLY3', which would be a z-dependent reference
875        density.
876    o cleaned up find_rho
877      - removed obsolete 'eqn' from the parameter list.
878    o added two new verification experiments: gop and goz
879      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
880    checkpoint46g_pre
881    
882    checkpoint46f_post
883    o Enable tangent linear (forward mode) gradient checks:
884      - extended active file handling to g_... files
885      - added TANGENT_SIMULATION to theSimulationMode
886      - extended grdchk package accordingly
887    o added tangent linear setup in verification/carbon/code_ftl
888    o added adjoint setup in verification/front_relax/code_ad
889    
890    checkpoint46e_post
891    o Added new equation of state -> MDJWF
892      - EOS of McDougall et al., 2002, JAOT, submitted
893      - caveat: the equation of state is only valid for a smaller (more
894        realistic?) range of values than JMD95P/Z and UNESCO
895      - added masks to the calculation of pressure in store_pressure
896      - added more check values for density in check_eos (ini_eos.F), some of
897        the old check values are out of the range of the MDJWF-eos, so don't
898        expect perfect matches for those
899    checkpoint46e_pre
900    
901    checkpoint46d_post
902    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
903      'OCEANICP', also initialised field pressure correctly in ini_eos in the
904      case of pressure coordinates. eosType='JMD95Z' in
905      combination with buoyancyRelation='OCEANICP' now causes an error.
906    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
907      in find_alpha/beta.
908    checkpoint46d_pre
909    
910    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
911      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
912    
913    checkpoint46c_post
914    o Changes necessary for ocean in p-coordinates
915     -  Added new buoyancy relation = 'OCEANICP'
916     -  Added new parameters = gravitySign (this used to be contained inside
917        the factor dRdZ which I added when we first switched to R coordinates).
918     X GM/Redi is not compatible (yet)
919     X bottom drag and no-slip need to be debugged.
920    checkpoint46c_pre
921    
922    checkpoint46b_post
923    o Added new equation of state -> JMD95Z and JMD95P
924      - EOS of Jackett and McDougall, 1995, JAOT
925      - moved all EOS parameters into EOS.h
926      - new routines ini_eos.F, store_pressure.F
927    o Added UNESCO EOS, but not recommended because it requires
928      in-situ temperature (see JMD95)
929    o Modified formatting for knudsen2.f in utils/knudsen2 and added
930      unesco.f to be used with POLY3
931    checkpoint46b_pre
932    
933    checkpoint46a_post
934    o Added (atmospheric) pressure loading
935      - new field in FFIELDS.h, etc...
936      - new cpp flag ATMOSPHERIC_LOADING
937    o Changed hFacC to _hFacC in calc_phi_hyd.F
938    o Added SHORTWAVE_HEATING to some files for consistency
939    checkpoint46a_pre
940    
941    checkpoint46

950      - modif's of existing cost functions
951    o Adjoint-related bug fixes in kpp:
952      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
953      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
954    o autodiff package
955      - flow directives:

967    
968    checkpoint45d_post
969    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
970    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
971      (affects plume_on_slope "cg2d" output)
972    o add new parameter deltaTfreesurf for free-surface time stepping
973    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
974    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
975    o change phiMin in exp1 (to agree with documentation)
976    o add new flags:
977     - T,S forcing inside/outside Adams-Bashforth
978     - turn off temp,salt advection and/or forcing
979     - for each tracer, define internal flag for multiDimAdvection & A-B
980    o monitor: change definition of KE to check conservation of Energy
981    
982    checkpoint45c_post
983    o Removed f90 comments ("!")

993    o included CPP option SINGLE_LAYER_MODE in thermodynamics
994      to configure barotropic setup (Martin Losch)
995    o moved some initialisations within bi,bj loop in dynamics
996      (TAF flow dependency)
997    o in initialise_varia, moved call packages_init_variables
998      before convective_adjustment_init
999      (corresponding adjustment of TAF tape initialisation).
1000    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1001    
1002    checkpoint45a_post
1003    o compute Rho over the whole domain (extend iMin,jMin indices)
1004    o specific exchange for X-slice domain (case Ny=1)
1005    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1006    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1007    
1008    checkpoint44h_post = checkpoint45
1009    o Fix to restore differentiability:
1010      place at which packages_init_variables is called in
1011      initialise_varia is crucial for reverse control flow.
1012    o modifications in GMRedi to enable stable adjoint
1013      (corresponding modif's in thermodynamics, dynamics)

1021    
1022    checkpoint44h_pre
1023    o vertical grid option: allow to put the Interface at the middle between
1024      2 cell-centers ; replace delZ in pkg/kpp by drF.
1025    o GM Advective form: Tracers are advected using the residual transport (=
1026      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1027    
1028    checkpoint44g_post
1029    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1030      results) ; ifdef missing in thermodynamics.F
1031    
1032    checkpoint44f_pre,checkpoint44f_post
1033    o added PTRACERS package
1034      This allows an arbitrary number of passive tracers to be integrated
1035      forward simultaneously with the dynamicaly model.
1036      + Implemented so far:
1037        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1038        - I/O and checkpointing
1039        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1040      + Not implemented so far:
1041        - KPP
1042        - OBCS
1043      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1044        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1045        line in data.pkg.
1046      + This package is disabled by default since it increases storage.
1047    
1048    
1049    o testscript: added -cleanup option
1050    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter

1053    checkpoint44e_pre,post
1054    o re-wrote convective adjustment to use pre-calculated weights
1055      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1056      Adds:    model/src/convective_weights.F, convectively_mixtracer.F

1063      on IBM SP3)
1064    o in genmake added variable MAKEDEPEND
1065      plus resetting for case SunOS
1066    o added timer_stats.c routine for IBM SP3
1067    o removed variables in dynamics
1068    !!! I forgot to create tag chkpt44d_pre !!!
1069    !!! But chkpt44d_pre = chkpt44c_post    !!!
1070    
1071    o real fresh water flux implemented with non-linear free-surface.
1072    
1073    chkpt44c_pre,post
1074    o few fix (mask in shap_s2, EmPmR in external_field_load,
1075      USE_NATURAL_BCS in solve_for_P);
1076    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1077    
1078    checkpoint44b_pre/_post
1079    o merge of relevant stuff from the ecco-branch:
1080      - genmake: removed $S64 overwrite for case SunOS
1081      - pkg/exf: update and corrections for field swapping and obcs

1092    
1093    checkpoint44
1094    o fix bug in mom_vi_del2uv
1095    o select when filters are applied ; add options to zonal_filter (data.zonfilt)

1106    
1107    checkpoint42
1108      Fixed AD-related problems:
1109    o Store directives up-to-date with re-arranged Adams-Bashforth
1110      (mainly thermodynamics.F)
1111    o New store directives for multi-dim. advection schemes
1112      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1113      * new common block and key passkey

1115    o Modified store directives for split of dynamics/thermodynamics
1116      for the case ALLOW_KPP
1117    o Cleaned argument list for timestep_tracer.F

1119    checkpoint41
1120    o re-formatted/added comments in prologues of key subroutines
1121      to work with protex
1122    
1123    checkpoint40
1124    o moved calc_gs, calc_gt and calc_tr1 back to model/src
1125    o added FLT (floats) package from Arne along with demo. experiment
1126    o re-arranged Adams-Bashforth scheme for tracers to allow easier
1127      implementation of forward-in-time forcing terms
1128    o more mods for non-linear free-surface including new variable
1129    o modified multi-dim method to work on cube
1130    o bug fix in KPP (from DM)

1141      
1142    checkpoint40pre8
1143    o new package rw/
1144      Added method for dumping intermediate local arrays:
1145      mdsio_writetile - same as mdsio_writefield except works from inside
1146                        bi,bj loop
1147      mdsio_writelocal - same as mdsio_writetile except works for local
1148                         arrays
1149      write_local_r? - higher-level wrapper for mdsio_writelocal
1150      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1151      Example given at end of mom_vecinv.F that dumps some local arrays.
1152    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1153      control flux-form versus vector invariant code.
1154      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1155      or genmake -DISABLE ...
1156    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1157      (additional storing is now needed for case vecinv;
1158      currently nothing implemented to switch this storing off
1159      in case fluxform is used since no CPP flag available).
1160    
1161    checkpoint40pre7
1162    o bug fix in dynamics.F
1163      calc_viscosity called before k=1,Nr loop.

1173    o Added diffkr, kapgm to control variables
1174    o bug fix in gmredi_slope_limit for ldd97
1175    
1176    checkpoint40pre5
1177    o proper initialization of Adams-Bashforth time stepping
1178      + uses forward step for very first step of model (iter=0)
1179    o re-generated *all* output since almost all output is modified by this
1180      change (sorry but we've been putting this one off for about 2 years)
1181      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1182        *not* regenerated since they are already out of date and I don't
1183        want to create the impression that they are suddenly working.
1184    o removed KAP stuff for DEC's
1185    o modified/added many .cvsignore files in */code and */input
1186    o added new expt "solid-body.cs-32x32x1"
1187      + this uses an alternative form of ini_curvilinear_grid.F which
1188        is not necessarily any better than the current one...
1189    
1190    checkpoint40pre4
1191    o added re-initialisations of utrans,vtrans,rtrans in
1192      calc_common_factors which are crucial for TAF.

1202    
1203  checkpoint40pre2  checkpoint40pre2
1204  o Updated to latest branch of AJA, JMC  o Updated to latest branch of AJA, JMC
