4      ==============================      ==============================
5    
6    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
7    o bug fix for pkg/seaice pickups
8    o change MNC call locations and add coordinate attributes
9    o mask vorticity at the corner ; affects global_ocean.cs output
10    o fix ini_curvilinear_grid ; test CS experiments with mpi
11    o aim.5l_cs: modify sea-ice fraction input file ; update output
12    o exf: Adding simple range check routine for exf fields after read
13    
14    checkpoint52k_post
15    o removed top-level directory "diags"
16      - we migrated these functions to pkg/timeave a long time ago
17    o fixed bug introduced in pkg/monitor
18    o accuracy ctrlprec = 32 insuffient for gradient checks using
19      averaged fields (I/O via cost_averages)
20      -> use ctrl.h in active_file*.F to control I/O precision.
21    o paramter list of CALL ADTHE_MAIN_LOOP
22    o added initial do_the_model_io to ecco
23    o set all ...Freq to zero after cost_final
24      taveFreq, dumpFreq, pChkptFreq
25    o MAIN and ECCO differentiability restored
26    
27    checkpoint52j_post
28    o fix nchklev in tamc.h for global_ocean...
29    o Bringing flow and store directives up-to-date
30    o Really weird thing!
31      call do_the_model_io from the_main_loop with parameters
32      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
33      TAF places a faulty re-call of initialise_varia
34      after cost_final call which should not be there!
35    checkpoint52j_pre
36    
37    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
38      error messages
39    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
40    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
41      debug output
42    o modfied mdsio_writefield.F to handle non-global files under exch2
43    o update AIM Cubed-Sphere exp (aim.5l_cs):
44      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
45    o update AIM Equatorial Channel exp:
46      use standard aim_v23 pkg and change the SST fields to be more realistic.
47    o globalFile now works with exch2
48    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
49      mon_vort3.F to make exch2 friendly with >1 tile per cube face
50    o limit timeave output for hi-res integrations
51    
52    checkpoint52i_post
53    o removed CPP_EEOPTIONS.h from verification/*/code
54    o updated the tiling for global_ocean_pressure
55    checkpoint52i_pre
56    
57    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
58      the old pkg/aim).
59    
60    checkpoint52h_pre
61    o shortened offending lines in exch2_send_rx?.template
62    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
63    o genmake2: add build & execute test for NetCDF code
64    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
65      old grid files, moved CPP_EEMACROS.h to pkg/exch2
66    o added useSingleCPUIO flag to monitor.F and mon_out.F
67    o added temporary hack for sea-ice dynamics on the cube:
68      metric terms are ignored and it is assumed that
69      there is no sea-ice on cube faces 1, 2, 4, and 5.
70    
71    checkpoint52f_post
72    o added exch2 cube routines to pkg/exch2
73    o modified hs94.cs-32x32x5 to use it
74    o added new grid files to hs94.cs-32x32x5
75    checkpoint52f_pre
76    
77    checkpoint52e_post
78    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
79      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
80    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
81      to work with implicit vertical advection and AB ;
82    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
83    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
84     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
85    checkpoint52e_pre
86    
87    o fix bug in impldiff when Nr=1 or Nr=2.
88    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
89    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
90    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
91      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
92    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
93    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
94    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
95    
96    checkpoint52d_post
97    o re-tiled many expts to allow comparison in multi-processor mode
98      - updated output accordingly
99      - changed hs94.128x64x5 to use intial T from file rather than use the
100        random number generator
101    o add infrastructure in model routines for fizhi and gridalt packages
102    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
103    o changes to permit hi-res, cubed-sphere, configuration
104      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
105      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
106      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
107        of surface winds for the cube
108      (A verification experiment, based on global_ocean.cs32x15, but with
109       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
110       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
111       complete with example surface forcing files and matlab scripts to look
112       at the output and compare it with that of global_ocean.cs32x15.)
113    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
114       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
115       to conform to the common rule.
116    o check-in the first version of the coupler + interfaces for multi-components
117       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
118       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
119       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
120       - ocean and atmos. share the same horizontal grid (no interpolation).
121       - exchanges between component and coupler is done in forward_step
122    o new verification experiment, cpl_aim+ocn:
123       coupled ocean - AIM atmosphere on cs32 grid.
124    
125    checkpoint52d_pre
126    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
127    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
128    
129    checkpoint52c_post
130    o Fixing OPTIONS files for use of exf:
131      - ALLOW_ECCO not needed
132      - ECCO_CPPOPTIONS.h should not be included from
133        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
134        as has been the case in the past
135      - All cal/exf related options are currently set in
136        single header file. Should remain so until we
137        agree on a consistent new policy.
138    o Removed all CPP options for cal package.
139      cal has no more CPP options.
140    o modified STOREs in GAD_ADVECTION
141    o corrected key comp. for passkey
142    
143    checkpoint52b_post
144    o new version: "thsice" of thermodynamic sea-ice pkg:
145     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
146     - modify fluxes but do not change theta directly;
147     - light cleaning of bulk_force pkg (still needed with thsice).
148     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
149       + output_thsice.txt to test thsice & bulk_force pkgs.
150    o put back grid & coriolis monitor output.
151    checkpoint52b_pre
152    
153    o call "do_the_model_io" at the beginning (=> dump initial state)
154    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
155    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
156      (need info on NUMBER_OF_PTRACERS)
157    o missing PTRACERS headers in some routines
158    o default tamc.h in pkg/autodiff supposed to crash
159      to ensure proper customization
160    
161    checkpoint52a_post
162    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
163      - moved surfaceTendencyTice from pkg/seaice to main code
164      - subroutine FREEZE_SURFACE now limits only surface temperature
165        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
166        => new output.txt for global_ocean.cs32x15 & global_with_exf
167      - keep the old version of FREEZE for backward compatibility;
168        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
169      - corresponding modifs for TAF directives
170    o added surface flux output variables to TIMEAVE_STATVARS
171    o time-averaged output for pkg/ptracers

177    o some bug fixes for #undef REAL4_IS_SLOW
178    
179    checkpoint52 = ecco_c52_e35
180    o after testing adjoints of checkpoint51u_post
181    
182    checkpoint51u_post
183    o this is the post-merge tag of the ecco-branch
184      (needs another clean checkout and re-testing)
185    o various natl_box_adjoint configs and results
186      but no input fields
187    o obcs adjoint not yet merged!
188    o adding ECCO global 1x1 and 2x2 degree configs
189    o updated/extended some store directives for seaice
190    o pkg/ecco now containes ecco-specific part of cost function
191    o top level routines the_main_loop, forward_step
192      supersede those in model/src/
193      previous input data.cost now in data.ecco
194      (new namelist ecco_cost_nml)
195    o in ctrl/ cleaned some cross-dependencies and updated CPP options
196    
197    checkpoint51t_post
198    o this is the pre-merge tag of the ecco-branch
199    
200    checkpoint51s_post
201    o cleanup: removed various obsolete #define-s
202    o pkg/grdchk
203      - renamed 'ph-grd 3' to 'grad-res'
204      - merged from ecco-branch
205        (remaining bug fixes for obcs gradient checks)
206      - additional high-precision output for testreport
207        (grep for 'precision_grdchk_result')
208    
209    checkpoint51r_post
210    o cleaned up or removed CPP_OPTIONS.h files
211    o updated results for some of the tests to reflect the new
212      optfiles (-ieee: -O0 instead of -O3)
213    
214    checkpoint51q_post
215    o cd_code:
216      - moved cd_scheme.F -> cd_code_scheme.F
217      - separate read_checkpoint from cd_code_ini_vars.F
218      - separated cd_code part from write_checkpoint
219      - updated AD_SOURCE, generated .flow
220      - added CD_CODE_VARS.h to the_main_loop
221      - Moving cd_code specific store dir.s to pkg/cd_code
222    o ctrl package totally restructured
223      - pack/unpack now optional and decoupled from
224        xx_/adxx_ I/O
225      - ctrl_pack/unpack cleaned

227      - confined inclusion of AD_CONFIG.h to where necessary.
228    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
229    
230    checkpoint51p_post
231    o create initial cd_code package
232      - WARNING: the initialization of fields within packages
233        is broken because INI_FIELDS (where READ_CHECKPOINT is
234        called) is called *before* PACKAGES_INIT_VARIABLES.
235        This seems to be backwards since
236        1) its important to initially zero the entire field including
237           the "halo" region
238        2) zeroing needs to be done *before* reading pickup info
239           and the pickup call might or might not happen in any
240           particular run
241      - this needs an overhaul for R2
242    o cleanup verification/*/code/GMREDI_OPTIONS.h
243    o cleanup testreport

253    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
254    o bug fix in find_alpha.F for MDJWF:
255      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
256        change rho -> rho-rhoConst
257      - replace call find_rho to find_rhonum
258    o initialisation of rFlx extended to full array (required by TAF)
259      and shifted to thermodynamics
260    o removed PTRACERS.h in ptracers routine

280         global_ocean.cs32x15, and global_with_exf)
281    o added surface flux output variables to TIMEAVE_STATVARS
282    
283    checkpoint51n_pre
284    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

419    o new ptracers.flow
420    o made ptracers_forcing same as external_forcing_s
421    o added verification for adjoint with ptracers
422      - adm. grdchk fail so far
423      - tlm. grdchk OK
424      - checked tapelev/comlev recomputations: OK
425    <<<checkpoint51b_pre
426    
427    checkpoint51a_post
428    o added code for biogeochemistry package
429      - new pkgs: dic, gchem
430      - new subroutine in ptracers
431    o modify code for biogeo packages
432      - in model/src and pkg/ptracers
433    
434    checkpoint51
435    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
436      - autodiff, ctrl, exf, grdchk, seaice
437      kept separate packages
438      - cost, ecco, obcs
439    o updating verification/internal_wave, verification/lab_sea
440      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
441    
442    checkpoint50i_post
443    o Preparing next differentiable checkpoint and sync
444      of MAIN vs. ecco-branch
445      - 1st step: this one is differentiable
446      - 2nd step: next(! not this) checkpoint will have updated packages
447                  from ecco-branch)
448    
449    checkpoint50h_post
450    o new package "land": provide surface BC for AIM.
451    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
452    o AIM: use true log-P extrapolation for near surface temp (= as in
453        F.Molteni paper) ; update aim.5l_cs output.
454    o New variable in PARM03 for more flexible pickups
455    o somewhat cleaned package initialisation sequence for
456      ctrl/ cost/ ecco/ in packages_... routines
457    
458    checkpoint50g_post
459    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
460      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
461      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
462        made the default because of faster convergence than ADI
463    
464    checkpoint50f_post
465    o exf totally restructured
466      - replaced all exf_set_ routines by one generic exf_set_gen.F
467        and made sure it's still differentiable
468      - split exf_getffields.F into new exf_bulkformulae.F
469      - exf_inscal_/exf_outscal_ suffixes consistent with field names

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

805      - added missing matlab routines
806      - added test of thermodynamics parallelization
807    
808    checkpoint47a_post
809    o new pkg: aim_v23
810     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
811       for now, keep the same surface forcing as before.
812     - Part-Cell implemented into AIM; check that Heat & Water are conserved
813     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
814     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
815    o add diagnostic of surface correction term in monitor output
816    
817    o bulk_force and therm_seaice
818    - Two packages:  bulk_force (Bulk forcing)
819      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
820    - Earlier integration from Stephaine Dutkiewicz

832        - GM_EXTRA_DIAGONAL
833        - GM_BOLUS_ADVEC )
834      * However, wrong gradient check problem remains unsolved.
835      * New CPP options have been introduced for different
836        tapering schemes
837    o external_fields_load now part of differentiation list
838    o pressure needs multiple storing;
839      would be nice to have store_pressure at beginning or
840      end of forward_step, e.g. by having phiHyd global (5-dim.)
841      (NB: pressure is needed for certain cases in find_rho,
842      which is also invoked through convective_adjustment).
843    o recomputations in find_rho for cases
844     'JMD95'/'UNESCO' or 'MDJWF' are OK.
845    o #define ATMOSPHERIC_LOADING should be differentiable
846    o ini_forcing shifted to begining of initialise_varia
847    o Incorporating QNVS line search routines into MITgcm
848      (this is separate code, and therefore not under pkg)
849      lsopt/, optim/
850    o Updated verification/carbon/
851      - #define GM_VISBECK_VARIABLE_K
852      - GM_taper_scheme    = 'ldd97'    
853    
854    checkpoint46n_post
855    Merging from release1_p8:
856    o verification/natl_box:
857      updating new external_fields_load routine
858    o New package: pkg/seaice
859      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
860      The sea-ice code is based on Hibler (1979-1980).
861      Two sea-ice dynamic solvers, ADI and LSR, are included.
862      In addition to computing prognostic sea-ice variables and diagnosing
863      the forcing/external data fields that drive the ocean model,
864      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
865      The implied surface heat flux is then stored in variable
866      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
867      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
868      non-local transport term.  Because this call precedes model
869      thermodynamics, temperature under sea-ice may not be "exactly" at
870      the freezing point by the time theta is dumped or time-averaged.
871      N.B.: fairly large differences in accuracy occur across
872            different platforms/compilers; comparison between
873            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
874            generated output gives:

881      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
882    o GAD:
883      - generated new common blocks to account for call of
884        same gad routines with differing traceridentities
885        (needed to modify tracerIdentity indices in GAD.h)
886      - generated separate common blocks for case useCubedSphereExchange
887        (Department of Futurology)
888      - parameter lists to gmredi_?transport: added tracerIdentity
889      - added new key indices to tamc.h
890    o external_fields_load:
891      - added this routine to TAF list
892      - needed to make some common blocks global and additional storing
893        along the same lines as exf package (checkpoint_lev?_directives.h)
894    o exf:
895      updated external forcing package
896      - bug fixes carried over from ecco-branch
897        (missing OBCS_OPTIONS.h in two routines)
898      - enable easy to use "no forcing".
899      - added exf I/O for atmospheric loading
900      - added exf I/O for runoff data
901      - transfered scaling between exf <-> MITgcm to exf namelist
902    o Adding new verification experiment global_with_exf.
903      This verification experiment is almost identical to the
904      global_ocean.90x40x15 experiment, except that it uses
905      the exf (and cal) package instead of the
906      external_fields_load routine (cf README file).
907    
908    checkpoint46m_post
909    o modified testscript to return -- when there are no lines of "%MON" output
910    o added new flag "quasiHydrostatic" for QH mode
911      and new routine quasihydrostaticterms()
912    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
913      New routine: mom_u_coriolis_nh()
914    o fixed sign of non-hydrostatic metric terms in u and v equations.
915      Depend on correct sign of gravitySign.
916    o added work.pc* to .cvsignore in aim directories using ifc
917    o introduced flag for controllin non-hydrostatic metric terms
918    o removed gravitySign from PARM04
919    o switched to g77/ifc from pgf77 in aim experiments
920    
921    checkpoint46l_post
922    o made convective adjustment work with pressure coordinates:
923     - changed the direction of k-loop in convective_adjustment.F for the
924       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
925     - adjusted the reference pressure k-index in convective_adjustment.F
926     - adjusted the convection condition in convect.F (in analogy to
927       calc_ivdc.F)
928     - convective_adjustment no longer computes anything on the halos
929     - removed the warnings about negative salinity from find_rho.F and
930       find_alpha.F; instead the new routine look_for_neg_salinity, called
931       at the beginning of find_rho, find_alpha, and find_beta, does a
932       check of the entire slice, if CPP-option
933       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
934    checkpoint46l_pre
935    
936    checkpoint46k_post
937    o fixed the verification/global_ocean.90x40x15 experiment:
938     - new bathymetry (the world according to A., JMC, and M.)
939     - new initial fields and forcing fields (*.bin files)
940     - new POLY3.COEFFS (for the next release one should switch to a full
941       equation of state: JMD95P or MDJWF)
942     - fixed several errors and redundancies in the data file
943     - experiment uses looped cells
944     - added matlab directory with diagnostic scripts for plotting of output
945    
946    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
947     - read AIM physics parameters from a file (data.aimphys)
948     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
949    
950    checkpoint46j_post
951    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
952    o move wVel computation at the end of the time step, in S/R integr_continuity
953    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
954    o update timeave pkg for wVel diagnostic.
955    checkpoint46j_pre
956    
957    checkpoint46i_post
958    o Clean up AIM package (and keep the results unchanged):
959      include CPP_OPTION and use IMPLICT NONE in all routines ;
960      declare all the variables _RL ; use _d 0 for all numerical constants.
961      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
962    
963    checkpoint46h_post
964    o cleaned up the use of rhoNil and rhoConst.
965      - rhoNil should only appear in the LINEAR equation of state, everywhere
966        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
967        and the dynamical equations are all divided by rhoConst
968    o introduced new parameter rhoConstFresh, a reference density of fresh
969      water, to remove the fresh water flux's dependence on rhoNil. The default
970      value is 999.8 kg/m^3
971    o cleanup up external_forcing.F and external_forcing_surf.F
972      - can now be used by both OCEANIC and OCEANICP
973    checkpoint46h_pre
974    
975     Added code to convert surface volume flux (fresh water) into
976     a mass flux when using P coordinates in the ocean (OCEANICP).
977     Note: It assumes you have set rho0=rhoConst=density of fresh water.
978    
979    checkpoint46g_post
980    o Include a new diagnostic variable phiHydLow for the ocean model
981      - in z-coordinates, it is the bottom pressure anomaly
982      - in p-coordinates, it is the sea surface elevation
983      - in both cases, these variable have global drift, reflecting the mass
984        drift in z-coordinates and the volume drift in p-coordinates
985      - included time averaging for phiHydLow, be aware of the drift!
986    o depth-dependent computation of Bo_surf for pressure coordinates
987      in the ocean (buoyancyRelation='OCEANICP')
988      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
989        Theta, Salinity, and Pressure in the parameter list. This routine is
990        presently contained in find_rho.F. This routine does not give the
991        correct density for 'POLY3', which would be a z-dependent reference
992        density.
993    o cleaned up find_rho
994      - removed obsolete 'eqn' from the parameter list.
995    o added two new verification experiments: gop and goz
996      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
997    checkpoint46g_pre
998    
999    checkpoint46f_post
1000    o Enable tangent linear (forward mode) gradient checks:
1001      - extended active file handling to g_... files
1002      - added TANGENT_SIMULATION to theSimulationMode
1003      - extended grdchk package accordingly
1004    o added tangent linear setup in verification/carbon/code_ftl
1005    o added adjoint setup in verification/front_relax/code_ad
1006    
1007    checkpoint46e_post
1008    o Added new equation of state -> MDJWF
1009      - EOS of McDougall et al., 2002, JAOT, submitted
1010      - caveat: the equation of state is only valid for a smaller (more
1011        realistic?) range of values than JMD95P/Z and UNESCO
1012      - added masks to the calculation of pressure in store_pressure
1013      - added more check values for density in check_eos (ini_eos.F), some of
1014        the old check values are out of the range of the MDJWF-eos, so don't
1015        expect perfect matches for those
1016    checkpoint46e_pre
1017    
1018    checkpoint46d_post
1019    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1020      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1021      case of pressure coordinates. eosType='JMD95Z' in
1022      combination with buoyancyRelation='OCEANICP' now causes an error.
1023    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1024      in find_alpha/beta.
1025    checkpoint46d_pre
1026    
1027    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1028      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1029    
1030    checkpoint46c_post
1031    o Changes necessary for ocean in p-coordinates
1032     -  Added new buoyancy relation = 'OCEANICP'
1033     -  Added new parameters = gravitySign (this used to be contained inside
1034        the factor dRdZ which I added when we first switched to R coordinates).
1035     X GM/Redi is not compatible (yet)
1036     X bottom drag and no-slip need to be debugged.
1037    checkpoint46c_pre
1038    
1039    checkpoint46b_post
1040    o Added new equation of state -> JMD95Z and JMD95P
1041      - EOS of Jackett and McDougall, 1995, JAOT
1042      - moved all EOS parameters into EOS.h
1043      - new routines ini_eos.F, store_pressure.F
1044    o Added UNESCO EOS, but not recommended because it requires
1045      in-situ temperature (see JMD95)
1046    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1047      unesco.f to be used with POLY3
1048    checkpoint46b_pre
1049    
1050    checkpoint46a_post
1051    o Added (atmospheric) pressure loading
1052      - new field in FFIELDS.h, etc...
1053      - new cpp flag ATMOSPHERIC_LOADING
1054    o Changed hFacC to _hFacC in calc_phi_hyd.F
1055    o Added SHORTWAVE_HEATING to some files for consistency
1056    checkpoint46a_pre
1057    
1058    checkpoint46
1059    further merges from release1_p5
1060    o new ctrl package
1061      - adopted from ECCO environment to enable optimization
1062      - added Eliassen Palm fluxes to controls
1063    o added Eliassen Palm flux controls to gradient check package
1064    o cost package
1065      - Compatible with new ctrl package
1066      - added Eliassen Palm cost hooks
1067      - modif's of existing cost functions
1068    o Adjoint-related bug fixes in kpp:
1069      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1070      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1071    o autodiff package
1072      - flow directives:
1073        + new for S/R do_the_model_io
1074        + enhanced for S/R checkpoint
1075        + new gmredi.flow
1076      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1077        disable adcommon.h/g_common.h by default.
1078      - fixed problem for adjoint of global_max
1079    o modified verification/carbon/

1082    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1083    o incorporated hooks for sponge layer code (external_forcing.F)
1084    
1085    checkpoint45d_post
1086    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1087    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1088      (affects plume_on_slope "cg2d" output)
1089    o add new parameter deltaTfreesurf for free-surface time stepping
1090    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1091    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1092    o change phiMin in exp1 (to agree with documentation)
1093    o add new flags:
1094     - T,S forcing inside/outside Adams-Bashforth
1095     - turn off temp,salt advection and/or forcing
1096     - for each tracer, define internal flag for multiDimAdvection & A-B
1097    o monitor: change definition of KE to check conservation of Energy
1098    
1099    checkpoint45c_post
1100    o Removed f90 comments ("!")
1101    o Modified initialisations to enable exf package for MITgcm
1102      (without invoking ECCO_PACKAGE).
1103    o modifications to gradient check package (Martin Losch)
1104      - enable centered differences
1105      - modified format of standard output
1106    
1107    checkpoint45b_post
1108    o cleaned exchange calls in cg2d
1109    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1110    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1111      to configure barotropic setup (Martin Losch)
1112    o moved some initialisations within bi,bj loop in dynamics
1113      (TAF flow dependency)
1114    o in initialise_varia, moved call packages_init_variables
1115      before convective_adjustment_init
1116      (corresponding adjustment of TAF tape initialisation).
1117    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1118    
1119    checkpoint45a_post
1120    o compute Rho over the whole domain (extend iMin,jMin indices)
1121    o specific exchange for X-slice domain (case Ny=1)
1122    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1123    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1124    
1125    checkpoint44h_post = checkpoint45
1126    o Fix to restore differentiability:
1127      place at which packages_init_variables is called in
1128      initialise_varia is crucial for reverse control flow.
1129    o modifications in GMRedi to enable stable adjoint
1130      (corresponding modif's in thermodynamics, dynamics)
1131    o added missing hook for sponge layer code in external_forcing
1132    o modified test cost functions
1133    o storing in gad_advection (plus removal of write(0,*)!
1134    o missing headers TR1.h added in convective_adjustment routines
1135    o errorMessageUnit set non-equal zero in eeboot
1136      (conflict on some platforms, e.g. IBM SP3)
1137    o modified carbon verif.
1138    
1139    checkpoint44h_pre
1140    o vertical grid option: allow to put the Interface at the middle between
1141      2 cell-centers ; replace delZ in pkg/kpp by drF.
1142    o GM Advective form: Tracers are advected using the residual transport (=
1143      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1144    
1145    checkpoint44g_post
1146    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1147      results) ; ifdef missing in thermodynamics.F
1148    
1149    checkpoint44f_pre,checkpoint44f_post
1150    o added PTRACERS package
1151      This allows an arbitrary number of passive tracers to be integrated
1152      forward simultaneously with the dynamicaly model.
1153      + Implemented so far:
1154        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1155        - I/O and checkpointing
1156        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1157      + Not implemented so far:
1158        - KPP
1159        - OBCS
1160      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1161        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1162        line in data.pkg.
1163      + This package is disabled by default since it increases storage.
1164    
1165    
1166    o testscript: added -cleanup option
1167    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1168                 b) enable to filter 2D fields.
1169    
1170    checkpoint44e_pre,post
1171    o re-wrote convective adjustment to use pre-calculated weights
1172      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1173      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1174      Original calls to convect() still in place.
1175    
1176    chkpt44d_pre,post
1177    o added missing EXCLUDE_MONITOR flags
1178    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1179      (incompatible typ in MIN/MAX expressions caused problems
1180      on IBM SP3)
1181    o in genmake added variable MAKEDEPEND
1182      plus resetting for case SunOS
1183    o added timer_stats.c routine for IBM SP3
1184    o removed variables in dynamics
1185    !!! I forgot to create tag chkpt44d_pre !!!
1186    !!! But chkpt44d_pre = chkpt44c_post    !!!
1187    
1188    o real fresh water flux implemented with non-linear free-surface.
1189    
1190    chkpt44c_pre,post
1191    o few fix (mask in shap_s2, EmPmR in external_field_load,
1192      USE_NATURAL_BCS in solve_for_P);
1193    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1194    
1195    checkpoint44b_pre/_post
1196    o merge of relevant stuff from the ecco-branch:
1197      - genmake: removed $S64 overwrite for case SunOS
1198      - pkg/exf: update and corrections for field swapping and obcs
1199      - pkg/ecco: parameter lists for the_model_main, the_main_loop
1200                  harmonized between ECCO and MITgcm
1201      - pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
1202                      updated checkpointing_lev... lists for obcs
1203      - model/src: minor changes in forward_step, plot_field
1204                   added directive for divided adjoint in the_main_loop
1205      - pkg/mdsio: added mdsio_gl_slice
1206    
1207    o check parameters & config (chkpt44a_pre,post)
1208    o OBC and NonLin_FrSurf.
1209    
1210    checkpoint44
1211    o fix bug in mom_vi_del2uv

1213    o gmredi: fix Pb in the adiabatic form ; add options (.e.g. Bolus advection)
1214    o update AIM experiments (NCEP input files)
1215    o improve and extend diagnostics (Monitor, TimeAve with NonLin-FrSurf)
1216    o added some stuff for AD
1217    
1218    checkpoint43
1219    o added two new advection tests
1220    o added global 4x4 degree ocean test
1221    o added test of H&S94 with free surface on cube
1222    o some final mods for gradient check, adjoint,...
1223    
1224    checkpoint42
1225      Fixed AD-related problems:
1226    o Store directives up-to-date with re-arranged Adams-Bashforth
1227      (mainly thermodynamics.F)
1228    o New store directives for multi-dim. advection schemes
1229      * new CPP flag ALLOW_MULTI_DIM_ADVECTION
1230      * new common block and key passkey

1242    o added FLT (floats) package from Arne along with demo. experiment
1243    o re-arranged Adams-Bashforth scheme for tracers to allow easier
1244      implementation of forward-in-time forcing terms
1245    o more mods for non-linear free-surface including new variable
1246    o modified multi-dim method to work on cube
1247    o bug fix in KPP (from DM)
1248    
1249    checkpoint40pre9
1250    o added DST advection schemes

1258      
1259    checkpoint40pre8
1260    o new package rw/
1261      Added method for dumping intermediate local arrays:
1262      mdsio_writetile - same as mdsio_writefield except works from inside
1263                        bi,bj loop
1264      mdsio_writelocal - same as mdsio_writetile except works for local
1265                         arrays
1266      write_local_r? - higher-level wrapper for mdsio_writelocal
1267      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1268      Example given at end of mom_vecinv.F that dumps some local arrays.
1269    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1270      control flux-form versus vector invariant code.
1271      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1272      or genmake -DISABLE ...
1273    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1274      (additional storing is now needed for case vecinv;
1275      currently nothing implemented to switch this storing off
1276      in case fluxform is used since no CPP flag available).
1277    
1278    checkpoint40pre7
1279    o bug fix in dynamics.F
1280      calc_viscosity called before k=1,Nr loop.

1290    o Added diffkr, kapgm to control variables
1291    o bug fix in gmredi_slope_limit for ldd97
1292    
1293    checkpoint40pre5
1294    o proper initialization of Adams-Bashforth time stepping
1295      + uses forward step for very first step of model (iter=0)
1296    o re-generated *all* output since almost all output is modified by this
1297      change (sorry but we've been putting this one off for about 2 years)
1298      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1299        *not* regenerated since they are already out of date and I don't
1300        want to create the impression that they are suddenly working.
1301    o removed KAP stuff for DEC's
1302    o modified/added many .cvsignore files in */code and */input
1303    o added new expt "solid-body.cs-32x32x1"
1304      + this uses an alternative form of ini_curvilinear_grid.F which
1305        is not necessarily any better than the current one...
1306    
1307    checkpoint40pre4
1308    o added re-initialisations of utrans,vtrans,rtrans in
1309      calc_common_factors which are crucial for TAF.

1317    o split the_main_loop and re-introduced forward_step
1318    o some recomputations of nIter0 for TAMC
1319    
1320    checkpoint40pre2
1321    o Updated to latest branch of AJA, JMC
1322    o Added gradient check package
1323    o Added routines for passive tracer handling
1324    o Added carbon sequestration sensitivity experiment

1330       in addummy_in_stepping
1331     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1332     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1333     o Included following packages:
1334       cal: calendar
1335       exf: external forcing
1336       ecco: essential routines to control use of cal, exf
1337             (NB: this is not the full ECCO environment)
1338     o disabled some packages by default in genmake
1339    
1340    checkpoint38
1341     o see notes_c37_adj.txt
1342     o corrected wrong layer index in external_forcing_t
1343     o replaced the_main_loop/forward_step by the_main_loop
1344     o removed forceoutput from write_state
1345       (replaced criteria for initial/final state)
1346     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1347    
1348    checkpoint37
1349     o mdsio.F routine split and packaged in pkg/mdsio
1350       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1351        used unless genmake -disable=mdsio)
1352     o allow a more precise surface-geopotential gradient for the atmosphere
1353       taking into account the change in space of Alpha (=1/rho) at the surface.
1354     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1355       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1356     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1357       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1358       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1359     o Time-Average diagnostics defined as a pseudo package "timeave".
1360     o pickup files : old pickup (before c35) did not work with new code (c35
1361       and after) unless activating 2 commented lines in initialise-varia.
1362     o Non-Hydrostatic pickup file Pb fixed.
1363     o bug with Rigid-lid version (since c35) fixed.  
1364    
1365    checkpoint36
1366     o implement Crank-Nickelson barotropic time-stepping
1367     o recover Time-Average diagnostics
1368     o fix Pb in checkpoint (PR#19)
1369     o AIM become a standard package ; clean unused CPP_kees
1370    
1371    checkpoint35
1372     o subtantial rewrite of dynamics.f
1373     o allows staggered time-stepping
1374     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
1375     o added bottom drag (linear + quadratic)
1376    
1377    checkpoint34
1378     o Modified exchange routines for correct reverse simulation.
1379     o Added verification output to comply with bug fix in impldiff.F
1380       as of c33 (exp2, natl_box).
1381     o Corrected store directives in dynamics.F
1382     o Corrected array boundaries in impldiff.F
1383     o Corrected array dimensions in gmredi.

1386     o Added mdsio_gl.F for ECCO purposes.
1387    
1388    checkpoint33
1389     o Fixed bug in lower BC in impldiff.F
1390     o Fixed confusion about units of forcing arrays in FFIELDS.h
1391       namely Fu,Fv,Qnet,Qsw,EmPmR:
1392       - Removed verification/natl_box/code/external_fields_scale.F
1393         (did not differ from that in model/src)
1394       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
1395         (see FFIELDS.h for description)
1396       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
1397         kpp_calc.F and kpp_transport_t.F
1398       - Removed model/src/external_fields_scale.F and calls to it
1399       - verification/natl_box uses flux data with "atmospheric" sign so
1400         a special version of external_fields_load.F is used to
1401         change the data as it's read in. This way, the arrays
1402         have the right units and signs at all times tha a user could
1403         possibly use them.
1404     o Corrected genmake to delete a temporary file during configuration
1405    
1406    checkpoint32
1407     o Scaling of forcing fields moved from external_forcing.F to
1408       external_fields_scale.F, called directly after loading fields.
1409     o Surface relaxation terms added to surface tendency fields in
1410       extra subroutine.
1411     o impldiff.F changed to avoid storing by TAMC of huge intermediate
1412       fields.
1413     o Changes in GMRedi to comply with packaging structure.
1414     o Modifications and bug fixes in KPP package.
1415     o Verification experiment for KPP added (verification/nat_box/)
1416    
1417    checkpoint31
1418     o Packages interface brought in line with defined standard
1419       -> new routines packages_...F
1420       -> changes in initialise_fixed.F, initialise_varia.F
1421       -> enables initialisation interface for ECCO package
1422     o Rescaling of external forcing fields immediately after read
1423       (removed from external_forcing.F)
1424       -> new: surface_fields_scale.F
1425       -> affects ini_foorcing.F, external_fields_load.F
1426     o Computation of surface tendencies before tendency updates.
1427       -> new: external_forcing_surf.F
1428     o Change of variable names useGMRedi, useKPP, useECCO
1429     o Further changes in dynamics.F, impldiff.F for TAMC
1430     o Tested for experiments 0, 2, 4.
1431       - not yet tested for GMRedi.
1432       - not yet tested for KPP.
1433    
1434    checkpoint30
1435     o Updates for OBCs
1436     o New experiment for test OBCs (internal_wave)
1437     o New output.txt in verification/exp4/results/
1438     o Updates for KPP: calculation of viscosity corrected, new variables
1439       kpp_dumpFreq and kpp_taveFreq
1440     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
1441       and entry for T90 in genmake
1442    
1443    checkpoint29
1444     o packaged KPP and GM/Redi
1445    
1446    checkpoint28
1447     o Corrected initialization of hFacMin for difference vertical coordinates
1448     o Modified calculation of partial cell thickness to more robust algorithm
1449     o config_summary.F: replaced write_1D_... by write_0D_...
1450       read_write.F: added subroutines write_0D_...
1451     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
1452       included some initialisations required for TAMC.
1453     o routine calc_isoslopes: modified sqrt computation to make it
1454       differentiable for zero argument.
1455     o routines dynamics, impldiff:
1456       included store directives and tape key computations required for TAMC.
1457     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
1458    
1459    checkpoint27
1460     o fixed calc_isoslopes() to so that cancellation of terms in tensor
1461       formulation works properly with variable resolution.
1462     o restructured the calling tree between the_model_main() and dynamics()
1463     o split initialise() into initialise_fixed() and initialise_varia()
1464     o introduced initialization file pSurfInitFile for free surface (cg2d_x)
1465       in new routine ini_psurf()
1466    
1467    checkpoint26
1468     o moved some #ifdef in optional routines to encompass everything
1469       except the argument declarations. This was using up some memory.
1470     o fixed macros like _ADT to work with both versions of Linux cpp
1471     o cleaned up some unused and uninitialized variables
1472       (helps when debugging with strict compile options)
1473     o split up CPP_EEOPTIONS.h into options and macros
1474       (macros are now in eesupp/inc/CPP_EEMACROS.h)
1475     o patch for 2 processor JAM mode
1476    
1477    checkpoint25
1478     o updates for OBCs and NH
1479     o dramatically reduced memory usage
1480     o added "JAM" routines for use on Artic network
1481     o parameterization of convection by implicit vertical diffusion
1482     o added a diagnostic of convective index
1483     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
1484       (this is was partly for OBCs and NH but also in anticipation of
1485        an explicit free-surface option)
1486     o initial state input files for U and V
1487    
1488    checkpoint24
1489     o Removed some spurious "REAL"s
1490     o Updated KPP to latest version from JPL

1495     o Multiple minor fixes (implicit none's, arguments to global_sum, etc.)
1496    
1497    checkpoint22
1498     o Made many small changes: implicit none, format(i5), etc...
1499     o Introduced KPP mixing scheme (compiles and runs but *not* tested)
1500    
1501    checkpoint21
1502     o Introduced new I/O package that supports direct-access records (mdsio.F)
1503     o Split-up mid-level I/O routines
1504     o Updated input data for experiments 0,1,2,4 and 5
1505     o Finally removed the genmake.* scripts (everyone seems happy with genmake)
1506    
1507    checkpoint20
1508     o Tidied up open-boundaries some more
1509     o Added non-hydrostatic code
1510     o Fixed some input data

1533     o Minor changes to exchange routines to support
1534       accumulation in reverse mode. Adjoint of an
1535       assignment is an addition.
1536     o Changes to support compilation by TAMC (LR(1)
1537       syntax) and by g77 under Linux ( 72 character
1538       limit ).
1539    
1540    checkpoint15
1541     Rewrote exchange routines to allow
1542     o General tile <-> tile connectivity.
1543     o TAMC reverse mode flag ( is this really needed? )
1544     o Variable width overlap and exchange region widths.
1545     o Hooks for sharing data via DMA, Arctic, Memory Channel,
1546       shmput/shmget, VIA, SYSV shmem and every other cool
1547       communication method.
1548    
1549    checkpoint14

1552    
1553    checkpoint13
1554     Release which corrects global_max problem and a couple
1555     of KGM time-averaging diagnostic errors. Also contains
1556     a double-gyre experiment setup as well as the baseline
1557     4 degree global template. The double gyre template is
1558     organised to allow it to be applied automatically to
1559     the baseline configuration.
1560    
1561    branch-point-rdot
1562     A few tidy-ups have been made bt the real point of this
1563     check-point (excuse the pun) is to allow a branch to be
1564     made for the purposes of adding the rDot alterations.
1565     I don't want to commit the rDot to the main-trunk until
1566     we've actually tested it...
1567    
1568    checkpoint12
1569     Tidy up and added generic genmake script (formerly
