21    checkpoint52i_pre
22    
23    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
24      the old pkg/aim).
25    
26    checkpoint52h_pre
27    o shortened offending lines in exch2_send_rx?.template
28    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator

36    
37    checkpoint52f_post
38    o added exch2 cube routines to pkg/exch2
39    o modified hs94.cs-32x32x5 to use it

41    checkpoint52f_pre
42    
43    checkpoint52e_post
44    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
45      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
46    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
47      to work with implicit vertical advection and AB ;
48    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
49    o update output (gad_calc_rhs.F changes affect truncation error) of exp:

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

143    o some bug fixes for #undef REAL4_IS_SLOW
144    
145    checkpoint52 = ecco_c52_e35
146    o after testing adjoints of checkpoint51u_post
147    
148    checkpoint51u_post
149    o this is the post-merge tag of the ecco-branch
150      (needs another clean checkout and re-testing)
151    o various natl_box_adjoint configs and results
152      but no input fields
153    o obcs adjoint not yet merged!
154    o adding ECCO global 1x1 and 2x2 degree configs
155    o updated/extended some store directives for seaice
156    o pkg/ecco now containes ecco-specific part of cost function
157    o top level routines the_main_loop, forward_step
158      supersede those in model/src/
159      previous input data.cost now in data.ecco
160      (new namelist ecco_cost_nml)
161    o in ctrl/ cleaned some cross-dependencies and updated CPP options
162    
163    checkpoint51t_post
164    o this is the pre-merge tag of the ecco-branch
165    
166    checkpoint51s_post

168    o pkg/grdchk
169      - renamed 'ph-grd 3' to 'grad-res'
170      - merged from ecco-branch
171        (remaining bug fixes for obcs gradient checks)
172      - additional high-precision output for testreport
173        (grep for 'precision_grdchk_result')
174    
175    checkpoint51r_post
176    o cleaned up or removed CPP_OPTIONS.h files
177    o updated results for some of the tests to reflect the new
178      optfiles (-ieee: -O0 instead of -O3)
179    
180    checkpoint51q_post
181    o cd_code:
182      - moved cd_scheme.F -> cd_code_scheme.F
183      - separate read_checkpoint from cd_code_ini_vars.F
184      - separated cd_code part from write_checkpoint
185      - updated AD_SOURCE, generated .flow

187      - Moving cd_code specific store dir.s to pkg/cd_code
188    o ctrl package totally restructured
189      - pack/unpack now optional and decoupled from
190        xx_/adxx_ I/O

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

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

419        F.Molteni paper) ; update aim.5l_cs output.
420    o New variable in PARM03 for more flexible pickups
421    o somewhat cleaned package initialisation sequence for
422      ctrl/ cost/ ecco/ in packages_... routines
423    
424    checkpoint50g_post
425    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
426      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
427      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
428        made the default because of faster convergence than ADI
429    
430    checkpoint50f_post
431    o exf totally restructured
432      - replaced all exf_set_ routines by one generic exf_set_gen.F
433        and made sure it's still differentiable
434      - split exf_getffields.F into new exf_bulkformulae.F
435      - exf_inscal_/exf_outscal_ suffixes consistent with field names
436      - updated adjoint/makefile and relevant verif. accordingly
437    
438    checkpoint50f_pre
439     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
440          + change Evap over land. (update aim.5l_cs output)
441     o added missing .cvsignores and made uniform across expts
442     o changed configuration of tidal_basin_2d expt
443     o added pkg/debug functions for tracing code in fatal crashes
444     o tidied pkg/monitor to use MONITOR_OPTIONS.h
445     o new fn in pkg/monitor to stop model if solution grows too big
446     o removed lots of single quotes from comments
447    
448    checkpoint50e_post
449    o make KPP work with PTRACERS
450     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
451       nearly a copy of kpp_transport_s
452     - there is no analogue to SurfaceTendencyS, so I have to use
453       gPtr(of the surface layer) instead
454    o add a new platform SunFire+mpi (SunFire 15000) to genmake
455    checkpoint50e_pre
456    
457    checkpoint50d_post
458    o change kpp output from multiple-record state files to single-record state
459      files analogous to write_state.F
460    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
461      analogous to the cg2d-related output.
462    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
463      so that writing to internal file fn (with length 512) fails.
464    checkpoint50d_pre
465    
466    checkpoint50c_post
467    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
468    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
469    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
470    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
471    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
472    
473    checkpoint50c_pre
474    Merging from release1_p13:
475    o bug fix for pkg/seaice dynamic solver
476    o Added SEAICE_initialHEFF to pkg/seaice
477    
478    checkpoint50b_post
479    o store u*,v* in gU,V instead of in guNm1,gvNm1
480    o in order to put the momForcing out of the Adams-Bashforth:
481      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
482      to timestep.F
483    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
484    o re-generate output for highly sensitive test-exp:
485       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
486    
487    checkpoint50b_pre
488    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
489    o corrected CPP option mismatch in exf_Bulk... functions for case
490      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
491    
492    checkpoint50a_post
493    o Bug fix for merging between c50 and KPP.
494      ikey was passed from thermodynamics to kpp_calc via
495      common block rather than being recomputed in kpp_calc,
496      in contradiction with new key itdkey.
497      New key ikppkey created, and tamc.h headers updated.
498    
499    checkpoint50
500    - 2nd step of merge with ecco-branch:
501      merge changes in ecco-branch back into main trunk
502    - bug fix in find_alpha
503    - more storing in gmredi_calc_tensor.F, kpp_routines.F
504    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
505    - merged some sliced AD support routines
506    
507    checkpoint49
508    merged from ecco-branch:
509    o exf:
510      - Enable initialisation of forcing fields to constant
511        (runtime) values.
512      - in exf_getffields.F
513        Reduce i-/j-loop to interior domain, discarding overlaps.
514        That also fixes wrong TAF-key computations for key_1, key_2
515        with bulf formulae.
516      - exf_init.F modify #ifdef for exf_init_evap
517      - exf_getffieldrec.F, ctrl_getrec.F
518        The following INT-usages are not safe:
519          fldsecs  = int(fldsecs/fldperiod)*fldperiod
520          fldcount = int(fldsecs/fldperiod) + 1
521        and were modified.
522    o autodiff: checkpoint_lev...
523      - updated storing for bulk formulae (some arrays were missing)
524      - added state for seaice package
525      - synchronized with main branch
526    o DIVA:
527      Modif.s in
528      - the_main_loop.F
529      - the_model_main.F
530      and added cost_final_restore.F cost_final_store.F
531      o With these changes, it is possible to fully separate
532        the first forward run to compute the cost function (mdthe_main_loop)
533        and adjoint runs over individual DIVA intervals (adthe_main_loop)
534        into separate model executions.
535        This enables better tuning of DIVA to given queue sizes.
536      o Loss of cost function value in consecutive DIVA runs is
537        fixed by storing to 'costfinal' file.
538      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
539        beginning/end of adjoint integration is accounted for.
540      The current changes apply to TAF-1.4.26.
541      TAF has one remaining bug, requiring one manual change
542      (see MITgcm manual).
543    o cal: synchronized between MAIN and ecco-branch
544    
545    checkpoint48i_post
546    o Changes to restore differentiability of code w.r.t. previous tag
547      (mostly adding new routines to make list and replacing
548      pressure by totPhiHyd).
549    o Updated and merged grdchk package
550      - has both ADM and TLM checks
551      - works for single- and multi-proc.
552      - output cleaned
553      - worked successfully for parallel DIVA
554    o genmake:
555      - Adding -platform=SP4
556      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
557    o Modif. for DIVA:
558      ctrl_unpack should not be called in intermediate DIVA interval.
559      (similar thing would apply for active files such as
560      tbar, sbar, psbar, which should not be reinitialised;
561      only relevant for ecco-branch)
562    
563    checkpoint48h_post
564    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
565    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
566    o Added SEAICE_initialHEFF to pkg/seaice
567    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
568    
569    checkpoint48g_post
570    --- EOS:
571    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
572      store total Potential in totPhyHyd for diagnostics & EOS.
573    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
574    --- Pressure/geopotential gradient:
575    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
576    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
577      ( changes results of global_ocean_pressure )
578    o NLFS + z-coord.: add eta*Rho' contribution.
579    o accurate phiHyd when using interface-W at the middle between 2 centers
580     ( changes results of ideal_2D_oce )
581    o includes r* 2nd term in potential gradient.
582    
583    checkpoint48f_post
584    Merging from release1_p12:
585    o Modifications for using pkg/exf with pkg/seaice
586      - improved description of the various forcing configurations
587      - added basic radiation bulk formulae to pkg/exf
588      - units/sign fix for evap computation in exf_getffields.F
589      - updated verification/global_with_exf/results/output.txt
590    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
591      (SBO) core products, including oceanic mass, center-of-mass,
592      angular, and bottom pressure (see pkg/sbo/README.sbo).
593    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
594      to avoid negative values in shallow regions.
595      - updated verification/natl_box/results/output.txt
596      - updated verification/lab_sea/results/output.txt
597    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
598    o Added useSingleCpuIO option (see PARAMS.h).
599    o Updated useSingleCpuIO option in mdsio_writefield.F to
600      work with multi-field files, e.g., for single-file pickup.
601    o pkg/seaice:
602      - bug fix in growth.F: QNET for no shortwave case
603      - added HeffFile for specifying initial sea-ice thickness
604      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
605    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
606      kpp_transport_t.F, forward_step.F, and the_main_loop.F
607    o pkg/seaice:
608      - adjoint-friendly modifications
609      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
610    
611    checkpoint48e_post
612    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
613    o dynamics: change definition of computational domain & adapt mom_fluxform
614      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
615    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
616        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
617        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
618        global_ocean.90x40x15 global_with_exf global_ocean_pressure
619        inverted_barometer solid-body.cs-32x32x1
620      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
621    
622    checkpoint48d_post
623    o in preparation for r*:
624     a) use pre-computed gradient of hydrostatic potential:
625        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
626     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
627        => affects results of glob_oce_pressure (different truncation error)  
628      update output.txt of ideal_2D_oce & global_ocean_pressure
629    
630    checkpoint48d_pre
631    o in preparation for r*:
632      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
633      pass the 2 comp. of the grad. as arguments to momentum S/R.
634      but for the moment, only used if it does not change the results.
635    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
636    
637    checkpoint48c_post
638    Modifications in treatment of initial flux forcing controls
639    to avoid extra storing of flux fields.
640    
641    checkpoint48c_pre
642    o Added tidal_basin_2d experiment (currently 1D!)
643    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
644    
645    checkpoint48b_post
646    o r* coordinate added in #ifdef NONLIN_FRSURF block.
647     (modification to pressure gradient not yet implemented)
648    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
649      (for U & V) that are used for vertical advection of momentum.
650    
651    checkpoint48a_post
652    o In preparation for r*, use temp. array to compute vertical transport
653       in flux-form momentum pkg. => change results of few test-exp.
654      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
655                        lab_sea, natl_box & plume_on_slope
656    
657    checkpoint48
658    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
659    
660    checkpoint47j_post
661    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
662    o moved adexch from forward_step to addummy_in_stepping
663    o added exch in ctrl_map_...
664    o aveFreq.=0. at end of cost_final to avoid overwrite in
665      reverse checkpointing loop
666    o Yet more changes in gmredi:
667      * adgmredi_calc_tensor
668        avoiding all recomputation of gmredi_slope_limit
669      * adgmredi_x/y/rtransport
670        added flag for excessive storing to avoid recomp. of
671        u/v/rtans, dTdx/y/z
672        -> this is not really necessary and very memory-consuming
673      * adgmredi_slope_psi:
674        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
675      * gmredi_slope_limit
676        re-activated full calculation of taperfct for case 'ac02'
677    o updating verification/ adjoints of carbon, global_ocean.90x40x15
678    
679    checkpoint47i_post
680    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
681    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
682      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
683    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
684    o gmredi: fix few bugs.
685    
686    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
687    This will be a good checkpoint to plug into the ecco-branch.
688    o few modif.'s to get latest version adjointed
689      (mainly kick out code in ini_linear_phisurf)
690    o modif's to run adjoint with exactConserv
691    o case GM_BOLUS_ADVEC should be cleaned
692      S/R gmredi_slope_psi should be cleaned
693    o verification/carbon now has exactConserv=.TRUE.
694    
695    checkpoint47g_post
696    o time-average AIM output: becomes independent from statvars time-average
697      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
698    o After TAF bug fix:
699      Tested adjoint of gmredi package.
700      Tests were done with checkpoint47 rather than with latest
701      checkpoint47f_post since the latter is broken for the adjoint
702      verification/carbon/ contains both ADM and TLM gradient checks.
703    Here they are, before they get changed/lost/stolen.
704    Mostly modif.'s to fix numerical sensitivities.
705    Gradient checks OK for
706    - GM_taper_scheme:
707      * clipping
708      * ac02
709      * linear
710      * glw91
711      * dm95
712      * ldd97
713    - GMREDI_OPTIONS:
714      * GM_VISBECK_VARIABLE_K
715      * GM_NON_UNITY_DIAGONAL
716      * GM_EXTRA_DIAGONAL
717      * GM_BOLUS_ADVEC
718    in conjunction with data.gmredi parameters to be checked in
719    in a few minutes under verification/carbon/code/
720    
721    checkpoint47f_post
722    Merging from release1_p10:
723    o modifications for using pkg/exf with pkg/seaice
724      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
725        and SEAICE_EXTERNAL_FLUXES
726      - pkg/exf CPP options EXF_READ_EVAP and
727        EXF_NO_BULK_COMPUTATIONS
728      - usage examples are Experiments 8 and 9 in
729        verification/lab_sea/README
730      - verification/lab_sea default experiment now uses
731        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
732    
733    checkpoint47e_post
734    o created a tag prior to creating a branch
735    
736    checkpoint47d_post
737    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
738      at the bottom boundary had an erroneous half slip boundary condition
739    o added bottom drag and no slip boundary condition capabilities to
740      oceanic pressure coordinates code
741    o added new verification experiment global_ocean_pressure, this experiment is
742      also described in the tutorial section of the manual
743    checkpoint47d_pre
744    
745    checkpoint47c_post
746    o Added a verification experiment for a global cubed-sphere ocean run
747      -  verification/global_ocean.cubed32x32x30
748      -  uses pkg/therm_seaice and pkg/bulk_forcing
749    
750    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
751    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
752      when using P-coordinate; only implemented for atmospheric config.
753    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
754      NOTES: requires option NONLIN_FRSURF to be "#define".
755    o update advect_xz/results/output.txt (left from checkpoint44g_post)
756    
757    checkpoint47b_post
758    Merging from release1_p9:
759    o pkg/seaice
760      - removed GOTO's and added taf directives
761      - double precision constants to reduce the g77 (Linux)
762        to F77 (SGI) differences reported in release1_p8
763    o tools/genmake
764      - added SGI options
765    o verification/testscript
766      - updated to that of checkpoint47a_post
767    o verification/global_ocean.90x40x15/input/eedata
768      - modified for SGI f77 compatibility
769    o verification/lab_sea
770      - added description of sea-ice model
771      - added missing matlab routines
772      - added test of thermodynamics parallelization
773    
774    checkpoint47a_post
775    o new pkg: aim_v23
776     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
777       for now, keep the same surface forcing as before.
778     - Part-Cell implemented into AIM; check that Heat & Water are conserved
779     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
780     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
781    o add diagnostic of surface correction term in monitor output
782    
783    o bulk_force and therm_seaice
784    - Two packages:  bulk_force (Bulk forcing)
785      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
786    - Earlier integration from Stephaine Dutkiewicz
787      and Patrick Heimbach.
788    - Two ifdef statements for compile time,
789       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
790    
791    checkpoint47
792    differentiable version of checkpoint46n_post
793    o bug fix in quasihydrostaticterms
794    o * "clean" adjoint code (in terms of extensive recomputations)
795        can now be obtained for all GMREDI options (i.e. for
796        - GM_VISBECK_VARIABLE_K
797        - GM_NON_UNITY_DIAGONAL
798        - GM_EXTRA_DIAGONAL
799        - GM_BOLUS_ADVEC )
800      * However, wrong gradient check problem remains unsolved.
801      * New CPP options have been introduced for different
802        tapering schemes
803    o external_fields_load now part of differentiation list
804    o pressure needs multiple storing;
805      would be nice to have store_pressure at beginning or
806      end of forward_step, e.g. by having phiHyd global (5-dim.)
807      (NB: pressure is needed for certain cases in find_rho,
808      which is also invoked through convective_adjustment).
809    o recomputations in find_rho for cases
810     'JMD95'/'UNESCO' or 'MDJWF' are OK.
811    o #define ATMOSPHERIC_LOADING should be differentiable
812    o ini_forcing shifted to begining of initialise_varia
813    o Incorporating QNVS line search routines into MITgcm
814      (this is separate code, and therefore not under pkg)
815      lsopt/, optim/
816    o Updated verification/carbon/
817      - #define GM_VISBECK_VARIABLE_K
818      - GM_taper_scheme    = 'ldd97'    
819    
820    checkpoint46n_post
821    Merging from release1_p8:
822    o verification/natl_box:
823      updating new external_fields_load routine
824    o New package: pkg/seaice
825      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
826      The sea-ice code is based on Hibler (1979-1980).
827      Two sea-ice dynamic solvers, ADI and LSR, are included.
828      In addition to computing prognostic sea-ice variables and diagnosing
829      the forcing/external data fields that drive the ocean model,
830      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
831      The implied surface heat flux is then stored in variable
832      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
833      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
834      non-local transport term.  Because this call precedes model
835      thermodynamics, temperature under sea-ice may not be "exactly" at
836      the freezing point by the time theta is dumped or time-averaged.
837      N.B.: fairly large differences in accuracy occur across
838            different platforms/compilers; comparison between
839            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)

848    o GAD:
849      - generated new common blocks to account for call of
850        same gad routines with differing traceridentities
851        (needed to modify tracerIdentity indices in GAD.h)
852      - generated separate common blocks for case useCubedSphereExchange
853        (Department of Futurology)
854      - parameter lists to gmredi_?transport: added tracerIdentity
855      - added new key indices to tamc.h
856    o external_fields_load:
857      - added this routine to TAF list
858      - needed to make some common blocks global and additional storing
859        along the same lines as exf package (checkpoint_lev?_directives.h)
860    o exf:
861      updated external forcing package
862      - bug fixes carried over from ecco-branch
863        (missing OBCS_OPTIONS.h in two routines)
864      - enable easy to use "no forcing".
865      - added exf I/O for atmospheric loading
866      - added exf I/O for runoff data
867      - transfered scaling between exf <-> MITgcm to exf namelist
868    o Adding new verification experiment global_with_exf.
869      This verification experiment is almost identical to the
870      global_ocean.90x40x15 experiment, except that it uses
871      the exf (and cal) package instead of the
872      external_fields_load routine (cf README file).
873    
874    checkpoint46m_post
875    o modified testscript to return -- when there are no lines of "%MON" output
876    o added new flag "quasiHydrostatic" for QH mode
877      and new routine quasihydrostaticterms()
878    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
879      New routine: mom_u_coriolis_nh()
880    o fixed sign of non-hydrostatic metric terms in u and v equations.
881      Depend on correct sign of gravitySign.
882    o added work.pc* to .cvsignore in aim directories using ifc
883    o introduced flag for controllin non-hydrostatic metric terms
884    o removed gravitySign from PARM04
885    o switched to g77/ifc from pgf77 in aim experiments
886    
887    checkpoint46l_post
888    o made convective adjustment work with pressure coordinates:
889     - changed the direction of k-loop in convective_adjustment.F for the
890       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
891     - adjusted the reference pressure k-index in convective_adjustment.F
892     - adjusted the convection condition in convect.F (in analogy to
893       calc_ivdc.F)
894     - convective_adjustment no longer computes anything on the halos
895     - removed the warnings about negative salinity from find_rho.F and
896       find_alpha.F; instead the new routine look_for_neg_salinity, called
897       at the beginning of find_rho, find_alpha, and find_beta, does a
898       check of the entire slice, if CPP-option
899       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
900    checkpoint46l_pre
901    
902    checkpoint46k_post
903    o fixed the verification/global_ocean.90x40x15 experiment:
904     - new bathymetry (the world according to A., JMC, and M.)
905     - new initial fields and forcing fields (*.bin files)
906     - new POLY3.COEFFS (for the next release one should switch to a full
907       equation of state: JMD95P or MDJWF)
908     - fixed several errors and redundancies in the data file
909     - experiment uses looped cells
910     - added matlab directory with diagnostic scripts for plotting of output
911    
912    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
913     - read AIM physics parameters from a file (data.aimphys)
914     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
915    
916    checkpoint46j_post
917    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
918    o move wVel computation at the end of the time step, in S/R integr_continuity
919    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
920    o update timeave pkg for wVel diagnostic.
921    checkpoint46j_pre
922    
923    checkpoint46i_post
924    o Clean up AIM package (and keep the results unchanged):
925      include CPP_OPTION and use IMPLICT NONE in all routines ;
926      declare all the variables _RL ; use _d 0 for all numerical constants.
927      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
928    
929    checkpoint46h_post
930    o cleaned up the use of rhoNil and rhoConst.
931      - rhoNil should only appear in the LINEAR equation of state, everywhere
932        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
933        and the dynamical equations are all divided by rhoConst
934    o introduced new parameter rhoConstFresh, a reference density of fresh
935      water, to remove the fresh water flux's dependence on rhoNil. The default
936      value is 999.8 kg/m^3
937    o cleanup up external_forcing.F and external_forcing_surf.F
938      - can now be used by both OCEANIC and OCEANICP
939    checkpoint46h_pre
940    
941     Added code to convert surface volume flux (fresh water) into
942     a mass flux when using P coordinates in the ocean (OCEANICP).
943     Note: It assumes you have set rho0=rhoConst=density of fresh water.
944    
945    checkpoint46g_post
946    o Include a new diagnostic variable phiHydLow for the ocean model
947      - in z-coordinates, it is the bottom pressure anomaly
948      - in p-coordinates, it is the sea surface elevation
949      - in both cases, these variable have global drift, reflecting the mass
950        drift in z-coordinates and the volume drift in p-coordinates
951      - included time averaging for phiHydLow, be aware of the drift!
952    o depth-dependent computation of Bo_surf for pressure coordinates
953      in the ocean (buoyancyRelation='OCEANICP')
954      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
955        Theta, Salinity, and Pressure in the parameter list. This routine is
956        presently contained in find_rho.F. This routine does not give the
957        correct density for 'POLY3', which would be a z-dependent reference
958        density.
959    o cleaned up find_rho
960      - removed obsolete 'eqn' from the parameter list.
961    o added two new verification experiments: gop and goz
962      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
963    checkpoint46g_pre
964    
965    checkpoint46f_post
966    o Enable tangent linear (forward mode) gradient checks:
967      - extended active file handling to g_... files
968      - added TANGENT_SIMULATION to theSimulationMode
969      - extended grdchk package accordingly
970    o added tangent linear setup in verification/carbon/code_ftl
971    o added adjoint setup in verification/front_relax/code_ad
972    
973    checkpoint46e_post
974    o Added new equation of state -> MDJWF
975      - EOS of McDougall et al., 2002, JAOT, submitted
976      - caveat: the equation of state is only valid for a smaller (more
977        realistic?) range of values than JMD95P/Z and UNESCO
978      - added masks to the calculation of pressure in store_pressure
979      - added more check values for density in check_eos (ini_eos.F), some of
980        the old check values are out of the range of the MDJWF-eos, so don't
981        expect perfect matches for those
982    checkpoint46e_pre
983    
984    checkpoint46d_post
985    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
986      'OCEANICP', also initialised field pressure correctly in ini_eos in the
987      case of pressure coordinates. eosType='JMD95Z' in
988      combination with buoyancyRelation='OCEANICP' now causes an error.
989    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
990      in find_alpha/beta.
991    checkpoint46d_pre
992    
993    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
994      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
995    
996    checkpoint46c_post
997    o Changes necessary for ocean in p-coordinates
998     -  Added new buoyancy relation = 'OCEANICP'
999     -  Added new parameters = gravitySign (this used to be contained inside
1000        the factor dRdZ which I added when we first switched to R coordinates).
1001     X GM/Redi is not compatible (yet)
1002     X bottom drag and no-slip need to be debugged.
1003    checkpoint46c_pre
1004    
1005    checkpoint46b_post
1006    o Added new equation of state -> JMD95Z and JMD95P
1007      - EOS of Jackett and McDougall, 1995, JAOT
1008      - moved all EOS parameters into EOS.h
1009      - new routines ini_eos.F, store_pressure.F
1010    o Added UNESCO EOS, but not recommended because it requires
1011      in-situ temperature (see JMD95)
1012    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1013      unesco.f to be used with POLY3
1014    checkpoint46b_pre
1015    
1016    checkpoint46a_post
1017    o Added (atmospheric) pressure loading
1018      - new field in FFIELDS.h, etc...
1019      - new cpp flag ATMOSPHERIC_LOADING
1020    o Changed hFacC to _hFacC in calc_phi_hyd.F
1021    o Added SHORTWAVE_HEATING to some files for consistency
1022    checkpoint46a_pre
1023    
1024    checkpoint46
1025    further merges from release1_p5
1026    o new ctrl package
1027      - adopted from ECCO environment to enable optimization
1028      - added Eliassen Palm fluxes to controls
1029    o added Eliassen Palm flux controls to gradient check package
1030    o cost package
1031      - Compatible with new ctrl package
1032      - added Eliassen Palm cost hooks
1033      - modif's of existing cost functions
1034    o Adjoint-related bug fixes in kpp:
1035      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1036      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1037    o autodiff package
1038      - flow directives:
1039        + new for S/R do_the_model_io
1040        + enhanced for S/R checkpoint
1041        + new gmredi.flow
1042      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1043        disable adcommon.h/g_common.h by default.
1044      - fixed problem for adjoint of global_max
1045    o modified verification/carbon/
1046    o New setup for adjoint of global_ocean
1047    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1048    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1049    o incorporated hooks for sponge layer code (external_forcing.F)
1050    
1051    checkpoint45d_post
1052    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1053    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1054      (affects plume_on_slope "cg2d" output)
1055    o add new parameter deltaTfreesurf for free-surface time stepping
1056    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1057    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1058    o change phiMin in exp1 (to agree with documentation)
1059    o add new flags:
1060     - T,S forcing inside/outside Adams-Bashforth
1061     - turn off temp,salt advection and/or forcing
1062     - for each tracer, define internal flag for multiDimAdvection & A-B
1063    o monitor: change definition of KE to check conservation of Energy
1064    
1065    checkpoint45c_post
1066    o Removed f90 comments ("!")
1067    o Modified initialisations to enable exf package for MITgcm
1068      (without invoking ECCO_PACKAGE).
1069    o modifications to gradient check package (Martin Losch)
1070      - enable centered differences
1071      - modified format of standard output
1072    
1073    checkpoint45b_post
1074    o cleaned exchange calls in cg2d
1075    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1076    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1077      to configure barotropic setup (Martin Losch)
1078    o moved some initialisations within bi,bj loop in dynamics
1079      (TAF flow dependency)
1080    o in initialise_varia, moved call packages_init_variables
1081      before convective_adjustment_init
1082      (corresponding adjustment of TAF tape initialisation).
1083    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1084    
1085    checkpoint45a_post
1086    o compute Rho over the whole domain (extend iMin,jMin indices)
1087    o specific exchange for X-slice domain (case Ny=1)
1088    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1089    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1090    
1091    checkpoint44h_post = checkpoint45
1092    o Fix to restore differentiability:
1093      place at which packages_init_variables is called in
1094      initialise_varia is crucial for reverse control flow.
1095    o modifications in GMRedi to enable stable adjoint
1096      (corresponding modif's in thermodynamics, dynamics)
1097    o added missing hook for sponge layer code in external_forcing
1098    o modified test cost functions
1099    o storing in gad_advection (plus removal of write(0,*)!
1100    o missing headers TR1.h added in convective_adjustment routines
1101    o errorMessageUnit set non-equal zero in eeboot
1102      (conflict on some platforms, e.g. IBM SP3)
1103    o modified carbon verif.
1104    
1105    checkpoint44h_pre
1106    o vertical grid option: allow to put the Interface at the middle between
1107      2 cell-centers ; replace delZ in pkg/kpp by drF.
1108    o GM Advective form: Tracers are advected using the residual transport (=
1109      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1110    
1111    checkpoint44g_post
1112    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1113      results) ; ifdef missing in thermodynamics.F
1114    
1115    checkpoint44f_pre,checkpoint44f_post
1116    o added PTRACERS package
1117      This allows an arbitrary number of passive tracers to be integrated
1118      forward simultaneously with the dynamicaly model.
1119      + Implemented so far:
1120        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1121        - I/O and checkpointing
1122        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1123      + Not implemented so far:
1124        - KPP
1125        - OBCS
1126      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1127        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1128        line in data.pkg.
1129      + This package is disabled by default since it increases storage.
1130    
1131    
1132    o testscript: added -cleanup option
1133    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1134                 b) enable to filter 2D fields.

1136    checkpoint44e_pre,post
1137    o re-wrote convective adjustment to use pre-calculated weights
1138      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1139      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1140      Original calls to convect() still in place.
1141    
1142    chkpt44d_pre,post
1143    o added missing EXCLUDE_MONITOR flags
1144    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1145      (incompatible typ in MIN/MAX expressions caused problems
1146      on IBM SP3)
1147    o in genmake added variable MAKEDEPEND
1148      plus resetting for case SunOS
1149    o added timer_stats.c routine for IBM SP3
1150    o removed variables in dynamics
1151    !!! I forgot to create tag chkpt44d_pre !!!
1152    !!! But chkpt44d_pre = chkpt44c_post    !!!
1153    
1154    o real fresh water flux implemented with non-linear free-surface.
1155    
1156    chkpt44c_pre,post
1157    o few fix (mask in shap_s2, EmPmR in external_field_load,
1158      USE_NATURAL_BCS in solve_for_P);
1159    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1160    
1161    checkpoint44b_pre/_post

1169      - model/src: minor changes in forward_step, plot_field
1170                   added directive for divided adjoint in the_main_loop
1171      - pkg/mdsio: added mdsio_gl_slice
1172    
1173    o check parameters & config (chkpt44a_pre,post)
1174    o OBC and NonLin_FrSurf.
1175

1193      (mainly thermodynamics.F)
1194    o New store directives for multi-dim. advection schemes
1195      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1196      * new common block and key passkey
1197      (mainly gad_advection.F)
1198    o Modified store directives for split of dynamics/thermodynamics
1199      for the case ALLOW_KPP
1200    o Cleaned argument list for timestep_tracer.F

1205    
1206    checkpoint40
1207    o moved calc_gs, calc_gt and calc_tr1 back to model/src
1208    o added FLT (floats) package from Arne along with demo. experiment
1209    o re-arranged Adams-Bashforth scheme for tracers to allow easier

1227      Added method for dumping intermediate local arrays:
1228      mdsio_writetile - same as mdsio_writefield except works from inside
1229                        bi,bj loop
1230      mdsio_writelocal - same as mdsio_writetile except works for local
1231                         arrays
1232      write_local_r? - higher-level wrapper for mdsio_writelocal
1233      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1234      Example given at end of mom_vecinv.F that dumps some local arrays.
1235    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1236      control flux-form versus vector invariant code.
1237      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1238      or genmake -DISABLE ...
1239    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1240      (additional storing is now needed for case vecinv;
1241      currently nothing implemented to switch this storing off
1242      in case fluxform is used since no CPP flag available).
1243    
1244    checkpoint40pre7
1245    o bug fix in dynamics.F
1246      calc_viscosity called before k=1,Nr loop.
1247    o added some #ifdef's ALLOW_PASSIVE_TRACER
1248    o cleaned initialisations in ctrl_map_ini
1249      related to TAF
1250    
1251    checkpoint40pre6
1252    o split dynamics into thermodynamics & dynamics
1253    o corresponding split of calc_diffusivity into
1254      calc_diffusivity, calc_viscosity
1255      (kpp_calc_diff, kpp_calc_visc).
1256    o Added diffkr, kapgm to control variables
1257    o bug fix in gmredi_slope_limit for ldd97
1258    
1259    checkpoint40pre5
1260    o proper initialization of Adams-Bashforth time stepping
1261      + uses forward step for very first step of model (iter=0)
1262    o re-generated *all* output since almost all output is modified by this
1263      change (sorry but we've been putting this one off for about 2 years)
1264      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1265        *not* regenerated since they are already out of date and I don't
1266        want to create the impression that they are suddenly working.
1267    o removed KAP stuff for DEC's
1268    o modified/added many .cvsignore files in */code and */input
1269    o added new expt "solid-body.cs-32x32x1"
1270      + this uses an alternative form of ini_curvilinear_grid.F which
1271        is not necessarily any better than the current one...
1272    
1273    checkpoint40pre4
1274    o added re-initialisations of utrans,vtrans,rtrans in
1275      calc_common_factors which are crucial for TAF.
1276    o extended iMin,jMin range for calc_common_factors,
1277      calc_diffusivity
1278    o added option ALLOW_PASSIVE_TRACER
1279    o a few minor updates and fixes
1280    
1281    checkpoint40pre3
1282    o created calc_gtr1.F for gad package
1283    o split the_main_loop and re-introduced forward_step
1284    o some recomputations of nIter0 for TAMC
1285    
1286    checkpoint40pre2
1287    o Updated to latest branch of AJA, JMC
1288    o Added gradient check package

1290    o Added carbon sequestration sensitivity experiment
1291    
1292    checkpoint39

1295     o Corrected common blocks when fooling TAMC to produce adjoint I/O
1296       in addummy_in_stepping
1297     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1298     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1299     o Included following packages:
1300       cal: calendar
1301       exf: external forcing
1302       ecco: essential routines to control use of cal, exf
1303             (NB: this is not the full ECCO environment)
1304     o disabled some packages by default in genmake
1305    
1306    checkpoint38
1307     o see notes_c37_adj.txt
1308     o corrected wrong layer index in external_forcing_t
1309     o replaced the_main_loop/forward_step by the_main_loop
1310     o removed forceoutput from write_state
1311       (replaced criteria for initial/final state)
1312     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1313    
1314    checkpoint37
1315     o mdsio.F routine split and packaged in pkg/mdsio
1316       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1317        used unless genmake -disable=mdsio)
1318     o allow a more precise surface-geopotential gradient for the atmosphere
1319       taking into account the change in space of Alpha (=1/rho) at the surface.
1320     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1321       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1322     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1323       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1324       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1325     o Time-Average diagnostics defined as a pseudo package "timeave".
1326     o pickup files : old pickup (before c35) did not work with new code (c35
1327       and after) unless activating 2 commented lines in initialise-varia.
1328     o Non-Hydrostatic pickup file Pb fixed.
1329     o bug with Rigid-lid version (since c35) fixed.  
1330    
1331    checkpoint36
1332     o implement Crank-Nickelson barotropic time-stepping
1333     o recover Time-Average diagnostics
1334     o fix Pb in checkpoint (PR#19)
1335     o AIM become a standard package ; clean unused CPP_kees
1336    
1337    checkpoint35
1338     o subtantial rewrite of dynamics.f
1339     o allows staggered time-stepping
1340     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
1341     o added bottom drag (linear + quadratic)
1342    
1343    checkpoint34
1344     o Modified exchange routines for correct reverse simulation.
1345     o Added verification output to comply with bug fix in impldiff.F
1346       as of c33 (exp2, natl_box).
1347     o Corrected store directives in dynamics.F
1348     o Corrected array boundaries in impldiff.F
1349     o Corrected array dimensions in gmredi.
1350       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
1351     o Added routine GLOBAL_SUM_INT to global_sum.F
1352     o Added mdsio_gl.F for ECCO purposes.
1353    
1354    checkpoint33
1355     o Fixed bug in lower BC in impldiff.F
1356     o Fixed confusion about units of forcing arrays in FFIELDS.h
1357       namely Fu,Fv,Qnet,Qsw,EmPmR:
1358       - Removed verification/natl_box/code/external_fields_scale.F
1359         (did not differ from that in model/src)
1360       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
1361         (see FFIELDS.h for description)
1362       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
1363         kpp_calc.F and kpp_transport_t.F
1364       - Removed model/src/external_fields_scale.F and calls to it
1365       - verification/natl_box uses flux data with "atmospheric" sign so
1366         a special version of external_fields_load.F is used to
1367         change the data as it's read in. This way, the arrays
1368         have the right units and signs at all times tha a user could
1369         possibly use them.
1370     o Corrected genmake to delete a temporary file during configuration
1371    
1372    checkpoint32
1373     o Scaling of forcing fields moved from external_forcing.F to
1374       external_fields_scale.F, called directly after loading fields.
1375     o Surface relaxation terms added to surface tendency fields in
1376       extra subroutine.
1377     o impldiff.F changed to avoid storing by TAMC of huge intermediate
1378       fields.
1379     o Changes in GMRedi to comply with packaging structure.
1380     o Modifications and bug fixes in KPP package.
1381     o Verification experiment for KPP added (verification/nat_box/)
1382    
1383    checkpoint31
1384     o Packages interface brought in line with defined standard
1385       -> new routines packages_...F
1386       -> changes in initialise_fixed.F, initialise_varia.F
1387       -> enables initialisation interface for ECCO package
1388     o Rescaling of external forcing fields immediately after read
1389       (removed from external_forcing.F)
1390       -> new: surface_fields_scale.F
1391       -> affects ini_foorcing.F, external_fields_load.F
1392     o Computation of surface tendencies before tendency updates.
1393       -> new: external_forcing_surf.F
1394     o Change of variable names useGMRedi, useKPP, useECCO
1395     o Further changes in dynamics.F, impldiff.F for TAMC
1396     o Tested for experiments 0, 2, 4.
1397       - not yet tested for GMRedi.
1398       - not yet tested for KPP.
1399    
1400    checkpoint30
1401     o Updates for OBCs
1402     o New experiment for test OBCs (internal_wave)
1403     o New output.txt in verification/exp4/results/
1404     o Updates for KPP: calculation of viscosity corrected, new variables
1405       kpp_dumpFreq and kpp_taveFreq
1406     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
1407       and entry for T90 in genmake
1408    
1409    checkpoint29
1410     o packaged KPP and GM/Redi
1411    
1412    checkpoint28
1413     o Corrected initialization of hFacMin for difference vertical coordinates
1414     o Modified calculation of partial cell thickness to more robust algorithm
1415     o config_summary.F: replaced write_1D_... by write_0D_...
1416       read_write.F: added subroutines write_0D_...
1417     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
1418       included some initialisations required for TAMC.
1419     o routine calc_isoslopes: modified sqrt computation to make it
1420       differentiable for zero argument.
1421     o routines dynamics, impldiff:
1422       included store directives and tape key computations required for TAMC.
1423     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
1424    
1425    checkpoint27
1426     o fixed calc_isoslopes() to so that cancellation of terms in tensor
1427       formulation works properly with variable resolution.
1428     o restructured the calling tree between the_model_main() and dynamics()
1429     o split initialise() into initialise_fixed() and initialise_varia()
1430     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
1431       in new routine ini_psurf()
1432    
1433    checkpoint26
1434     o moved some #ifdef in optional routines to encompass everything
1435       except the argument declarations. This was using up some memory.
1436     o fixed macros like _ADT to work with both versions of Linux cpp
1437     o cleaned up some unused and uninitialized variables
1438       (helps when debugging with strict compile options)
1439     o split up CPP_EEOPTIONS.h into options and macros
1440       (macros are now in eesupp/inc/CPP_EEMACROS.h)
1441     o patch for 2 processor JAM mode
1442    
1443    checkpoint25
1444     o updates for OBCs and NH
1445     o dramatically reduced memory usage
1446     o added "JAM" routines for use on Artic network
1447     o parameterization of convection by implicit vertical diffusion
1448     o added a diagnostic of convective index
1449     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
1450       (this is was partly for OBCs and NH but also in anticipation of
1451        an explicit free-surface option)
1452     o initial state input files for U and V
1453    
1454    checkpoint24
1455     o Removed some spurious "REAL"s
1456     o Updated KPP to latest version from JPL

1461     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
1462    
1463    checkpoint22
1464     o Made many small changes: implicit none, format(i5), etc...
1465     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
1466    
1467    checkpoint21
1468     o Introduced new I/O package that supports direct-access records (mdsio.F)
1469     o Split-up mid-level I/O routines
1470     o Updated input data for experiments 0,1,2,4 and 5
1471     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
1472    
1473    checkpoint20
1474     o Tidied up open-boundaries some more
1475     o Added non-hydrostatic code
1476     o Fixed some input data

1485     o Split default parameters out of ini_parms.F into set_defaults.F.
1486    
1487    checkpoint18
1488     o Further changes for optional code generation with
1489       CPP - ugh!
1490    
1491    checkpoint17
1492     o Beginning to incorporating modularity
1493       for supporting atmos. and ocean configs.
1494     o Small changes for TAMC complinace
1495     o New ultra simple test case. Barotropic box
1496       configuration "exp0".
1497    
1498    checkpoint16
1499     o Minor changes to exchange routines to support
1500       accumulation in reverse mode. Adjoint of an
1501       assignment is an addition.
1502     o Changes to support compilation by TAMC (LR(1)
1503       syntax) and by g77 under Linux ( 72 character
1504       limit ).
1505    
1506    checkpoint15
1507     Rewrote exchange routines to allow
1508     o General tile <-> tile connectivity.
1509     o TAMC reverse mode flag ( is this really needed? )
1510     o Variable width overlap and exchange region widths.
1511     o Hooks for sharing data via DMA, Arctic, Memory Channel,
1512       shmput/shmget, VIA, SYSV shmem and every other cool
1513       communication method.
1514    
1515    checkpoint14
1516     Consistent isomorphism chages made. These allow dynamical core
1517     to support both pressure and meters as a vertical coordinate.
1518    
1519    checkpoint13
1520     Release which corrects global_max problem and a couple
1521     of KGM time-averaging diagnostic errors. Also contains
1522     a double-gyre experiment setup as well as the baseline
1523     4 degree global template. The double gyre template is
1524     organised to allow it to be applied automatically to
1525     the baseline configuration.
1526    
1527    branch-point-rdot
1528     A few tidy-ups have been made bt the real point of this
1529     check-point (excuse the pun) is to allow a branch to be
1530     made for the purposes of adding the rDot alterations.
1531     I don't want to commit the rDot to the main-trunk until
1532     we've actually tested it...
1533    
1534    checkpoint12
1535     Tidy up and added generic genmake script (formerly
