4      ==============================      ==============================
5    
6    o added useSingleCPUIO flag to monitor.F and mon_out.F
7    
8    checkpoint52f_post
9    o added exch2 cube routines to pkg/exch2
10    o modified hs94.cs-32x32x5 to use it
11    o added new grid files to hs94.cs-32x32x5
12    checkpoint52f_pre
13    
14    checkpoint52e_post
15    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
16      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
17    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
18      to work with implicit vertical advection and AB ;
19    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
20    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
21     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
22    checkpoint52e_pre
23    
24    o fix bug in impldiff when Nr=1 or Nr=2.
25    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
26    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
27    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
28      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
29    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
30    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
31    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
32    
33    checkpoint52d_post
34    o re-tiled many expts to allow comparison in multi-processor mode
35      - updated output accordingly
36      - changed hs94.128x64x5 to use intial T from file rather than use the
37        random number generator
38    o add infrastructure in model routines for fizhi and gridalt packages
39    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
40    o changes to permit hi-res, cubed-sphere, configuration
41      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
42      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
43      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
44        of surface winds for the cube
45      (A verification experiment, based on global_ocean.cs32x15, but with
46       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
47       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
48       complete with example surface forcing files and matlab scripts to look
49       at the output and compare it with that of global_ocean.cs32x15.)
50    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
51       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
52       to conform to the common rule.
53    o check-in the first version of the coupler + interfaces for multi-components
54       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
55       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
56       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
57       - ocean and atmos. share the same horizontal grid (no interpolation).
58       - exchanges between component and coupler is done in forward_step
59    o new verification experiment, cpl_aim+ocn:
60       coupled ocean - AIM atmosphere on cs32 grid.
61    
62    checkpoint52d_pre
63    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
64    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
65    
66    checkpoint52c_post
67    o Fixing OPTIONS files for use of exf:
68      - ALLOW_ECCO not needed
69      - ECCO_CPPOPTIONS.h should not be included from
70        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
71        as has been the case in the past
72      - All cal/exf related options are currently set in
73        single header file. Should remain so until we
74        agree on a consistent new policy.
75    o Removed all CPP options for cal package.
76      cal has no more CPP options.
77    o modified STOREs in GAD_ADVECTION
78    o corrected key comp. for passkey
79    
80    checkpoint52b_post
81    o new version: "thsice" of thermodynamic sea-ice pkg:
82     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
83     - modify fluxes but do not change theta directly;
84     - light cleaning of bulk_force pkg (still needed with thsice).
85     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
86       + output_thsice.txt to test thsice & bulk_force pkgs.
87    o put back grid & coriolis monitor output.
88    checkpoint52b_pre
89    
90    o call "do_the_model_io" at the beginning (=> dump initial state)
91    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
92    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
93      (need info on NUMBER_OF_PTRACERS)
94    o missing PTRACERS headers in some routines
95    o default tamc.h in pkg/autodiff supposed to crash
96      to ensure proper customization
97    
98    checkpoint52a_post
99    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
100      - moved surfaceTendencyTice from pkg/seaice to main code
101      - subroutine FREEZE_SURFACE now limits only surface temperature
102        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
103        => new output.txt for global_ocean.cs32x15 & global_with_exf
104      - keep the old version of FREEZE for backward compatibility;
105        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
106      - corresponding modifs for TAF directives
107    o added surface flux output variables to TIMEAVE_STATVARS
108    o time-averaged output for pkg/ptracers

114    o some bug fixes for #undef REAL4_IS_SLOW
115    
116    checkpoint52 = ecco_c52_e35
117    o after testing adjoints of checkpoint51u_post
118    
119    checkpoint51u_post
120    o this is the post-merge tag of the ecco-branch
121      (needs another clean checkout and re-testing)
122    o various natl_box_adjoint configs and results
123      but no input fields
124    o obcs adjoint not yet merged!
125    o adding ECCO global 1x1 and 2x2 degree configs
126    o updated/extended some store directives for seaice
127    o pkg/ecco now containes ecco-specific part of cost function
128    o top level routines the_main_loop, forward_step
129      supersede those in model/src/
130      previous input data.cost now in data.ecco
131      (new namelist ecco_cost_nml)
132    o in ctrl/ cleaned some cross-dependencies and updated CPP options
133    
134    checkpoint51t_post
135    o this is the pre-merge tag of the ecco-branch
136    
137    checkpoint51s_post
138    o cleanup: removed various obsolete #define-s
139    o pkg/grdchk
140      - renamed 'ph-grd 3' to 'grad-res'
141      - merged from ecco-branch
142        (remaining bug fixes for obcs gradient checks)
143      - additional high-precision output for testreport
144        (grep for 'precision_grdchk_result')
145    
146    checkpoint51r_post
147    o cleaned up or removed CPP_OPTIONS.h files
148    o updated results for some of the tests to reflect the new
149      optfiles (-ieee: -O0 instead of -O3)
150    
151    checkpoint51q_post
152    o cd_code:
153      - moved cd_scheme.F -> cd_code_scheme.F
154      - separate read_checkpoint from cd_code_ini_vars.F
155      - separated cd_code part from write_checkpoint
156      - updated AD_SOURCE, generated .flow
157      - added CD_CODE_VARS.h to the_main_loop
158      - Moving cd_code specific store dir.s to pkg/cd_code
159    o ctrl package totally restructured
160      - pack/unpack now optional and decoupled from
161        xx_/adxx_ I/O

164      - confined inclusion of AD_CONFIG.h to where necessary.
165    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
166    
167    checkpoint51p_post
168    o create initial cd_code package
169      - WARNING: the initialization of fields within packages
170        is broken because INI_FIELDS (where READ_CHECKPOINT is
171        called) is called *before* PACKAGES_INIT_VARIABLES.
172        This seems to be backwards since
173        1) its important to initially zero the entire field including
174           the "halo" region
175        2) zeroing needs to be done *before* reading pickup info
176           and the pickup call might or might not happen in any
177           particular run
178      - this needs an overhaul for R2
179    o cleanup verification/*/code/GMREDI_OPTIONS.h
180    o cleanup testreport

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

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

817    
818      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
819    o GAD:
820      - generated new common blocks to account for call of
821        same gad routines with differing traceridentities
822        (needed to modify tracerIdentity indices in GAD.h)
823      - generated separate common blocks for case useCubedSphereExchange
824        (Department of Futurology)
825      - parameter lists to gmredi_?transport: added tracerIdentity
826      - added new key indices to tamc.h
827    o external_fields_load:
828      - added this routine to TAF list
829      - needed to make some common blocks global and additional storing
830        along the same lines as exf package (checkpoint_lev?_directives.h)
831    o exf:
832      updated external forcing package
833      - bug fixes carried over from ecco-branch
834        (missing OBCS_OPTIONS.h in two routines)
835      - enable easy to use "no forcing".
836      - added exf I/O for atmospheric loading
837      - added exf I/O for runoff data
838      - transfered scaling between exf <-> MITgcm to exf namelist
839    o Adding new verification experiment global_with_exf.
840      This verification experiment is almost identical to the
841      global_ocean.90x40x15 experiment, except that it uses
842      the exf (and cal) package instead of the
843      external_fields_load routine (cf README file).
844    
845    checkpoint46m_post
846    o modified testscript to return -- when there are no lines of "%MON" output
847    o added new flag "quasiHydrostatic" for QH mode
848      and new routine quasihydrostaticterms()
849    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
850      New routine: mom_u_coriolis_nh()
851    o fixed sign of non-hydrostatic metric terms in u and v equations.
852      Depend on correct sign of gravitySign.
853    o added work.pc* to .cvsignore in aim directories using ifc
854    o introduced flag for controllin non-hydrostatic metric terms
855    o removed gravitySign from PARM04
856    o switched to g77/ifc from pgf77 in aim experiments
857    
858    checkpoint46l_post
859    o made convective adjustment work with pressure coordinates:
860     - changed the direction of k-loop in convective_adjustment.F for the
861       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
862     - adjusted the reference pressure k-index in convective_adjustment.F
863     - adjusted the convection condition in convect.F (in analogy to
864       calc_ivdc.F)
865     - convective_adjustment no longer computes anything on the halos
866     - removed the warnings about negative salinity from find_rho.F and
867       find_alpha.F; instead the new routine look_for_neg_salinity, called
868       at the beginning of find_rho, find_alpha, and find_beta, does a
869       check of the entire slice, if CPP-option
870       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
871    checkpoint46l_pre
872    
873    checkpoint46k_post
874    o fixed the verification/global_ocean.90x40x15 experiment:
875     - new bathymetry (the world according to A., JMC, and M.)
876     - new initial fields and forcing fields (*.bin files)
877     - new POLY3.COEFFS (for the next release one should switch to a full
878       equation of state: JMD95P or MDJWF)
879     - fixed several errors and redundancies in the data file
880     - experiment uses looped cells
881     - added matlab directory with diagnostic scripts for plotting of output
882    
883    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
884     - read AIM physics parameters from a file (data.aimphys)
885     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
886    
887    checkpoint46j_post
888    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
889    o move wVel computation at the end of the time step, in S/R integr_continuity
890    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
891    o update timeave pkg for wVel diagnostic.
892    checkpoint46j_pre
893    
894    checkpoint46i_post
895    o Clean up AIM package (and keep the results unchanged):
896      include CPP_OPTION and use IMPLICT NONE in all routines ;
897      declare all the variables _RL ; use _d 0 for all numerical constants.
898      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
899    
900    checkpoint46h_post
901    o cleaned up the use of rhoNil and rhoConst.
902      - rhoNil should only appear in the LINEAR equation of state, everywhere
903        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
904        and the dynamical equations are all divided by rhoConst
905    o introduced new parameter rhoConstFresh, a reference density of fresh
906      water, to remove the fresh water flux's dependence on rhoNil. The default
907      value is 999.8 kg/m^3
908    o cleanup up external_forcing.F and external_forcing_surf.F
909      - can now be used by both OCEANIC and OCEANICP
910    checkpoint46h_pre
911    
912     Added code to convert surface volume flux (fresh water) into
913     a mass flux when using P coordinates in the ocean (OCEANICP).
914     Note: It assumes you have set rho0=rhoConst=density of fresh water.
915    
916    checkpoint46g_post
917    o Include a new diagnostic variable phiHydLow for the ocean model
918      - in z-coordinates, it is the bottom pressure anomaly
919      - in p-coordinates, it is the sea surface elevation
920      - in both cases, these variable have global drift, reflecting the mass
921        drift in z-coordinates and the volume drift in p-coordinates
922      - included time averaging for phiHydLow, be aware of the drift!
923    o depth-dependent computation of Bo_surf for pressure coordinates
924      in the ocean (buoyancyRelation='OCEANICP')
925      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
926        Theta, Salinity, and Pressure in the parameter list. This routine is
927        presently contained in find_rho.F. This routine does not give the
928        correct density for 'POLY3', which would be a z-dependent reference
929        density.
930    o cleaned up find_rho
931      - removed obsolete 'eqn' from the parameter list.
932    o added two new verification experiments: gop and goz
933      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
934    checkpoint46g_pre
935    
936    checkpoint46f_post
937    o Enable tangent linear (forward mode) gradient checks:
938      - extended active file handling to g_... files
939      - added TANGENT_SIMULATION to theSimulationMode
940      - extended grdchk package accordingly
941    o added tangent linear setup in verification/carbon/code_ftl
942    o added adjoint setup in verification/front_relax/code_ad
943    
944    checkpoint46e_post
945    o Added new equation of state -> MDJWF
946      - EOS of McDougall et al., 2002, JAOT, submitted
947      - caveat: the equation of state is only valid for a smaller (more
948        realistic?) range of values than JMD95P/Z and UNESCO
949      - added masks to the calculation of pressure in store_pressure
950      - added more check values for density in check_eos (ini_eos.F), some of
951        the old check values are out of the range of the MDJWF-eos, so don't
952        expect perfect matches for those
953    checkpoint46e_pre
954    
955    checkpoint46d_post
956    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
957      'OCEANICP', also initialised field pressure correctly in ini_eos in the
958      case of pressure coordinates. eosType='JMD95Z' in
959      combination with buoyancyRelation='OCEANICP' now causes an error.
960    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
961      in find_alpha/beta.
962    checkpoint46d_pre
963    
964    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
965      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
966    
967    checkpoint46c_post
968    o Changes necessary for ocean in p-coordinates
969     -  Added new buoyancy relation = 'OCEANICP'
970     -  Added new parameters = gravitySign (this used to be contained inside
971        the factor dRdZ which I added when we first switched to R coordinates).
972     X GM/Redi is not compatible (yet)
973     X bottom drag and no-slip need to be debugged.
974    checkpoint46c_pre
975    
976    checkpoint46b_post
977    o Added new equation of state -> JMD95Z and JMD95P
978      - EOS of Jackett and McDougall, 1995, JAOT
979      - moved all EOS parameters into EOS.h
980      - new routines ini_eos.F, store_pressure.F
981    o Added UNESCO EOS, but not recommended because it requires
982      in-situ temperature (see JMD95)
983    o Modified formatting for knudsen2.f in utils/knudsen2 and added
984      unesco.f to be used with POLY3
985    checkpoint46b_pre
986    
987    checkpoint46a_post
988    o Added (atmospheric) pressure loading
989      - new field in FFIELDS.h, etc...
990      - new cpp flag ATMOSPHERIC_LOADING
991    o Changed hFacC to _hFacC in calc_phi_hyd.F
992    o Added SHORTWAVE_HEATING to some files for consistency
993    checkpoint46a_pre
994    
995    checkpoint46
996    further merges from release1_p5
997    o new ctrl package
998      - adopted from ECCO environment to enable optimization
999      - added Eliassen Palm fluxes to controls
1000    o added Eliassen Palm flux controls to gradient check package
1001    o cost package
1002      - Compatible with new ctrl package
1003      - added Eliassen Palm cost hooks
1004      - modif's of existing cost functions
1005    o Adjoint-related bug fixes in kpp:
1006      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1007      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1008    o autodiff package
1009      - flow directives:
1010        + new for S/R do_the_model_io
1011        + enhanced for S/R checkpoint
1012        + new gmredi.flow
1013      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1014        disable adcommon.h/g_common.h by default.
1015      - fixed problem for adjoint of global_max
1016    o modified verification/carbon/
1017    o New setup for adjoint of global_ocean
1018    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1019    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1020    o incorporated hooks for sponge layer code (external_forcing.F)
1021    
1022    checkpoint45d_post
1023    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1024    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1025      (affects plume_on_slope "cg2d" output)
1026    o add new parameter deltaTfreesurf for free-surface time stepping
1027    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1028    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1029    o change phiMin in exp1 (to agree with documentation)
1030    o add new flags:
1031     - T,S forcing inside/outside Adams-Bashforth
1032     - turn off temp,salt advection and/or forcing
1033     - for each tracer, define internal flag for multiDimAdvection & A-B
1034    o monitor: change definition of KE to check conservation of Energy
1035    
1036    checkpoint45c_post
1037    o Removed f90 comments ("!")
1038    o Modified initialisations to enable exf package for MITgcm
1039      (without invoking ECCO_PACKAGE).
1040    o modifications to gradient check package (Martin Losch)
1041      - enable centered differences
1042      - modified format of standard output
1043    
1044    checkpoint45b_post
1045    o cleaned exchange calls in cg2d
1046    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1047    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1048      to configure barotropic setup (Martin Losch)
1049    o moved some initialisations within bi,bj loop in dynamics
1050      (TAF flow dependency)
1051    o in initialise_varia, moved call packages_init_variables
1052      before convective_adjustment_init
1053      (corresponding adjustment of TAF tape initialisation).
1054    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1055    
1056    checkpoint45a_post
1057    o compute Rho over the whole domain (extend iMin,jMin indices)
1058    o specific exchange for X-slice domain (case Ny=1)
1059    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1060    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1061    
1062    checkpoint44h_post = checkpoint45
1063    o Fix to restore differentiability:
1064      place at which packages_init_variables is called in
1065      initialise_varia is crucial for reverse control flow.
1066    o modifications in GMRedi to enable stable adjoint
1067      (corresponding modif's in thermodynamics, dynamics)
1068    o added missing hook for sponge layer code in external_forcing
1069    o modified test cost functions
1070    o storing in gad_advection (plus removal of write(0,*)!
1071    o missing headers TR1.h added in convective_adjustment routines
1072    o errorMessageUnit set non-equal zero in eeboot
1073      (conflict on some platforms, e.g. IBM SP3)
1074    o modified carbon verif.
1075    
1076    checkpoint44h_pre
1077    o vertical grid option: allow to put the Interface at the middle between
1078      2 cell-centers ; replace delZ in pkg/kpp by drF.
1079    o GM Advective form: Tracers are advected using the residual transport (=
1080      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1081    
1082    checkpoint44g_post
1083    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1084      results) ; ifdef missing in thermodynamics.F
1085    
1086    checkpoint44f_pre,checkpoint44f_post
1087    o added PTRACERS package
1088      This allows an arbitrary number of passive tracers to be integrated
1089      forward simultaneously with the dynamicaly model.
1090      + Implemented so far:
1091        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1092        - I/O and checkpointing
1093        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1094      + Not implemented so far:
1095        - KPP
1096        - OBCS
1097      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1098        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1099        line in data.pkg.
1100      + This package is disabled by default since it increases storage.
1101    
1102    
1103    o testscript: added -cleanup option
1104    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1105                 b) enable to filter 2D fields.
1106    
1107    checkpoint44e_pre,post
1108    o re-wrote convective adjustment to use pre-calculated weights
1109      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1110      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1111      Original calls to convect() still in place.
1112    
1113    chkpt44d_pre,post
1114    o added missing EXCLUDE_MONITOR flags
1115    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1116      (incompatible typ in MIN/MAX expressions caused problems
1117      on IBM SP3)
1118    o in genmake added variable MAKEDEPEND
1119      plus resetting for case SunOS
1120    o added timer_stats.c routine for IBM SP3
1121    o removed variables in dynamics
1122    !!! I forgot to create tag chkpt44d_pre !!!
1123    !!! But chkpt44d_pre = chkpt44c_post    !!!
1124    
1125    o real fresh water flux implemented with non-linear free-surface.
1126    
1127    chkpt44c_pre,post
1128    o few fix (mask in shap_s2, EmPmR in external_field_load,
1129      USE_NATURAL_BCS in solve_for_P);
1130    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1131    
1132    checkpoint44b_pre/_post
1133    o merge of relevant stuff from the ecco-branch:
1134      - genmake: removed $S64 overwrite for case SunOS
1135      - pkg/exf: update and corrections for field swapping and obcs
1136      - pkg/ecco: parameter lists for the_model_main, the_main_loop
1137                  harmonized between ECCO and MITgcm
1138      - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
1139                      updated checkpointing_lev... lists for obcs
1140      - model/src: minor changes in forward_step, plot_field
1141                   added directive for divided adjoint in the_main_loop
1142      - pkg/mdsio: added mdsio_gl_slice
1143    
1144    o check parameters & config (chkpt44a_pre,post)
1145    o OBC and NonLin_FrSurf.
1146    
1147    checkpoint44
1148    o fix bug in mom_vi_del2uv
1149    o select when filters are applied ; add options to zonal_filter (data.zonfilt)

1156    o added two new advection tests
1157    o added global 4x4 degree ocean test
1158    o added test of H&S94 with free surface on cube
1159    o some final mods for gradient check, adjoint,...
1160    
1161    checkpoint42
1162      Fixed AD-related problems:
1163    o Store directives up-to-date with re-arranged Adams-Bashforth
1164      (mainly thermodynamics.F)
1165    o New store directives for multi-dim. advection schemes
1166      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1167      * new common block and key passkey
1168      (mainly gad_advection.F)
1169    o Modified store directives for split of dynamics/thermodynamics
1170      for the case ALLOW_KPP
1171    o Cleaned argument list for timestep_tracer.F
1172    
1173    checkpoint41
1174    o re-formatted/added comments in prologues of key subroutines
1175      to work with protex
1176    
1177    checkpoint40
1178    o moved calc_gs, calc_gt and calc_tr1 back to model/src
1179    o added FLT (floats) package from Arne along with demo. experiment
1180    o re-arranged Adams-Bashforth scheme for tracers to allow easier
1181      implementation of forward-in-time forcing terms
1182    o more mods for non-linear free-surface including new variable
1183    o modified multi-dim method to work on cube
1184    o bug fix in KPP (from DM)
1185    
1186    checkpoint40pre9
1187    o added DST advection schemes
1188    o fix MPI bug on SGI's
1189    o modifications for non-linear free-surface
1190    o fixed conditionals for fixed flow/passive tracer only mode
1191    o added tension/strain form of stress tensor
1192    o changes to commenting of arguments for TAF/TAMC
1193    o added/updated many matlab scripts
1194    o added multi-dimensional advection method for tracers
1195      
1196    checkpoint40pre8
1197    o new package rw/
1198      Added method for dumping intermediate local arrays:
1199      mdsio_writetile - same as mdsio_writefield except works from inside
1200                        bi,bj loop
1201      mdsio_writelocal - same as mdsio_writetile except works for local
1202                         arrays
1203      write_local_r? - higher-level wrapper for mdsio_writelocal
1204      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1205      Example given at end of mom_vecinv.F that dumps some local arrays.
1206    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1207      control flux-form versus vector invariant code.
1208      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1209      or genmake -DISABLE ...
1210    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1211      (additional storing is now needed for case vecinv;
1212      currently nothing implemented to switch this storing off
1213      in case fluxform is used since no CPP flag available).
1214    
1215    checkpoint40pre7
1216    o bug fix in dynamics.F
1217      calc_viscosity called before k=1,Nr loop.
1218    o added some #ifdef's ALLOW_PASSIVE_TRACER
1219    o cleaned initialisations in ctrl_map_ini
1220      related to TAF
1221    
1222    checkpoint40pre6
1223    o split dynamics into thermodynamics & dynamics
1224    o corresponding split of calc_diffusivity into
1225      calc_diffusivity, calc_viscosity
1226      (kpp_calc_diff, kpp_calc_visc).
1227    o Added diffkr, kapgm to control variables
1228    o bug fix in gmredi_slope_limit for ldd97
1229    
1230    checkpoint40pre5
1231    o proper initialization of Adams-Bashforth time stepping
1232      + uses forward step for very first step of model (iter=0)
1233    o re-generated *all* output since almost all output is modified by this
1234      change (sorry but we've been putting this one off for about 2 years)
1235      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1236        *not* regenerated since they are already out of date and I don't
1237        want to create the impression that they are suddenly working.
1238    o removed KAP stuff for DEC's
1239    o modified/added many .cvsignore files in */code and */input
1240    o added new expt "solid-body.cs-32x32x1"
1241      + this uses an alternative form of ini_curvilinear_grid.F which
1242        is not necessarily any better than the current one...
1243    
1244    checkpoint40pre4
1245    o added re-initialisations of utrans,vtrans,rtrans in
1246      calc_common_factors which are crucial for TAF.
1247    o extended iMin,jMin range for calc_common_factors,
1248      calc_diffusivity
1249    o added option ALLOW_PASSIVE_TRACER
1250    o a few minor updates and fixes
1251    
1252    checkpoint40pre3
1253    o created calc_gtr1.F for gad package
1254    o split the_main_loop and re-introduced forward_step
1255    o some recomputations of nIter0 for TAMC
1256    
1257    checkpoint40pre2
1258    o Updated to latest branch of AJA, JMC
1259    o Added gradient check package

1261    o Added carbon sequestration sensitivity experiment
1262    
1263    checkpoint39
1264     o Modifications and fixes to support TAMC

1266     o Corrected common blocks when fooling TAMC to produce adjoint I/O
1267       in addummy_in_stepping
1268     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1269     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1270     o Included following packages:
1271       cal: calendar
1272       exf: external forcing
1273       ecco: essential routines to control use of cal, exf
1274             (NB: this is not the full ECCO environment)
1275     o disabled some packages by default in genmake
1276    
1277    checkpoint38
1278     o see notes_c37_adj.txt
1279     o corrected wrong layer index in external_forcing_t
1280     o replaced the_main_loop/forward_step by the_main_loop
1281     o removed forceoutput from write_state

1283     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1284    
1285    checkpoint37
1286     o mdsio.F routine split and packaged in pkg/mdsio
1287       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1288        used unless genmake -disable=mdsio)
1289     o allow a more precise surface-geopotential gradient for the atmosphere
1290       taking into account the change in space of Alpha (=1/rho) at the surface.
1291     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1292       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1293     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1294       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1295       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1296     o Time-Average diagnostics defined as a pseudo package "timeave".
1297     o pickup files : old pickup (before c35) did not work with new code (c35
1298       and after) unless activating 2 commented lines in initialise-varia.
1299     o Non-Hydrostatic pickup file Pb fixed.
1300     o bug with Rigid-lid version (since c35) fixed.  
1301    
1302    checkpoint36
1303     o implement Crank-Nickelson barotropic time-stepping
1304     o recover Time-Average diagnostics
1305     o fix Pb in checkpoint (PR#19)
1306     o AIM become a standard package ; clean unused CPP_kees
1307    
1308    checkpoint35
1309     o subtantial rewrite of dynamics.f
1310     o allows staggered time-stepping
1311     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
1312     o added bottom drag (linear + quadratic)
1313    
1314    checkpoint34
1315     o Modified exchange routines for correct reverse simulation.
1316     o Added verification output to comply with bug fix in impldiff.F
1317       as of c33 (exp2, natl_box).
1318     o Corrected store directives in dynamics.F
1319     o Corrected array boundaries in impldiff.F
1320     o Corrected array dimensions in gmredi.
1321       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
1322     o Added routine GLOBAL_SUM_INT to global_sum.F
1323     o Added mdsio_gl.F for ECCO purposes.
1324    
1325    checkpoint33
1326     o Fixed bug in lower BC in impldiff.F
1327     o Fixed confusion about units of forcing arrays in FFIELDS.h
1328       namely Fu,Fv,Qnet,Qsw,EmPmR:
1329       - Removed verification/natl_box/code/external_fields_scale.F
1330         (did not differ from that in model/src)
1331       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
1332         (see FFIELDS.h for description)
1333       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
1334         kpp_calc.F and kpp_transport_t.F
1335       - Removed model/src/external_fields_scale.F and calls to it
1336       - verification/natl_box uses flux data with "atmospheric" sign so
1337         a special version of external_fields_load.F is used to
1338         change the data as it's read in. This way, the arrays
1339         have the right units and signs at all times tha a user could
1340         possibly use them.
1341     o Corrected genmake to delete a temporary file during configuration
1342    
1343    checkpoint32
1344     o Scaling of forcing fields moved from external_forcing.F to
1345       external_fields_scale.F, called directly after loading fields.
1346     o Surface relaxation terms added to surface tendency fields in
1347       extra subroutine.
1348     o impldiff.F changed to avoid storing by TAMC of huge intermediate
1349       fields.
1350     o Changes in GMRedi to comply with packaging structure.
1351     o Modifications and bug fixes in KPP package.
1352     o Verification experiment for KPP added (verification/nat_box/)
1353    
1354    checkpoint31
1355     o Packages interface brought in line with defined standard
1356       -> new routines packages_...F
1357       -> changes in initialise_fixed.F, initialise_varia.F
1358       -> enables initialisation interface for ECCO package
1359     o Rescaling of external forcing fields immediately after read
1360       (removed from external_forcing.F)
1361       -> new: surface_fields_scale.F
1362       -> affects ini_foorcing.F, external_fields_load.F
1363     o Computation of surface tendencies before tendency updates.
1364       -> new: external_forcing_surf.F
1365     o Change of variable names useGMRedi, useKPP, useECCO
1366     o Further changes in dynamics.F, impldiff.F for TAMC
1367     o Tested for experiments 0, 2, 4.
1368       - not yet tested for GMRedi.
1369       - not yet tested for KPP.
1370    
1371    checkpoint30
1372     o Updates for OBCs
1373     o New experiment for test OBCs (internal_wave)
1374     o New output.txt in verification/exp4/results/
1375     o Updates for KPP: calculation of viscosity corrected, new variables
1376       kpp_dumpFreq and kpp_taveFreq
1377     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
1378       and entry for T90 in genmake

1381     o packaged KPP and GM/Redi
1382    
1383    checkpoint28
1384     o Corrected initialization of hFacMin for difference vertical coordinates
1385     o Modified calculation of partial cell thickness to more robust algorithm
1386     o config_summary.F: replaced write_1D_... by write_0D_...
1387       read_write.F: added subroutines write_0D_...
1388     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
1389       included some initialisations required for TAMC.
1390     o routine calc_isoslopes: modified sqrt computation to make it
1391       differentiable for zero argument.
1392     o routines dynamics, impldiff:
1393       included store directives and tape key computations required for TAMC.
1394     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
1395    
1396    checkpoint27
1397     o fixed calc_isoslopes() to so that cancellation of terms in tensor
1398       formulation works properly with variable resolution.
1399     o restructured the calling tree between the_model_main() and dynamics()
1400     o split initialise() into initialise_fixed() and initialise_varia()
1401     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
1402       in new routine ini_psurf()
1403    
1404    checkpoint26
1405     o moved some #ifdef in optional routines to encompass everything
1406       except the argument declarations. This was using up some memory.
1407     o fixed macros like _ADT to work with both versions of Linux cpp
1408     o cleaned up some unused and uninitialized variables
1409       (helps when debugging with strict compile options)
1410     o split up CPP_EEOPTIONS.h into options and macros
1411       (macros are now in eesupp/inc/CPP_EEMACROS.h)
1412     o patch for 2 processor JAM mode
1413    
1414    checkpoint25
1415     o updates for OBCs and NH
1416     o dramatically reduced memory usage
1417     o added "JAM" routines for use on Artic network

1419     o added a diagnostic of convective index
1420     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
1421       (this is was partly for OBCs and NH but also in anticipation of
1422        an explicit free-surface option)
1423     o initial state input files for U and V
1424    
1425  checkpoint24  checkpoint24
