3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    o MNC:
6      - make myThid the last argument for all subroutines
7      - new default for the grid files: NO halos
8      - add useMNC and other run-time flags
9      - separate per-file-group handling of the unlimited dimension
10      - early initialization of MNC w/ flags read at the eeboot stage
11        and lookup tables set in initialize_fixed
12      - write all MNC output to a freshly-created directory
13    o thermodynamics sea-ice (thsice) is now tested with testreport.
14    o test exp. advect_cs: use the standard cs32 grid ; update output.
15    o Added functionality to grdchk:
16      pick global i,j,k position (or nearest wet) where to perform check.
17    
18    checkpoint52l_post
19    o new land formulation:
20      a) use ground enthalpy as prognostic variable to ensure exact
21         energy conservation.
22      b) account for water temperature and for latent heat of freezing
23         in all processes (rain, run-off, ground storage)
24      c) compute surface and ground temperature implicitly.
25    o aim_v23 modification for new land model:
26      a) Treat separately land / ocean / sea-ice surface fluxes
27         to allow implicit computation of land & sea-ice surface temp.
28      b) add snow precipitation.
29    checkpoint52l_pre
30    
31    o fix problem (when 1 tile is empty) in min/max monitor.
32    o fix bug in timeAve (u,vZetatave in common block)
33    o no restoring terms under ice for pkg/seaice
34    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
35    o bug fix for pkg/seaice pickups
36    o change MNC call locations and add coordinate attributes
37    o mask vorticity at the corner ; affects global_ocean.cs output
38    o fix ini_curvilinear_grid ; test CS experiments with mpi
39    o aim.5l_cs: modify sea-ice fraction input file ; update output
40    o exf: Adding simple range check routine for exf fields after read
41    
42    checkpoint52k_post
43    o removed top-level directory "diags"
44      - we migrated these functions to pkg/timeave a long time ago
45    o fixed bug introduced in pkg/monitor
46    o accuracy ctrlprec = 32 insuffient for gradient checks using
47      averaged fields (I/O via cost_averages)
48      -> use ctrl.h in active_file*.F to control I/O precision.
49    o paramter list of CALL ADTHE_MAIN_LOOP
50    o added initial do_the_model_io to ecco
51    o set all ...Freq to zero after cost_final
52      taveFreq, dumpFreq, pChkptFreq

54    
55    checkpoint52j_post
56    o fix nchklev in tamc.h for global_ocean...
57    o Bringing flow and store directives up-to-date
58    o Really weird thing!
59      call do_the_model_io from the_main_loop with parameters
60      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
61      TAF places a faulty re-call of initialise_varia
62      after cost_final call which should not be there!
63    checkpoint52j_pre
64    
65    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
66      error messages
67    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
68    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
69      debug output
70    o modfied mdsio_writefield.F to handle non-global files under exch2
71    o update AIM Cubed-Sphere exp (aim.5l_cs):
72      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
73    o update AIM Equatorial Channel exp:
74      use standard aim_v23 pkg and change the SST fields to be more realistic.
75    o globalFile now works with exch2
76    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
77      mon_vort3.F to make exch2 friendly with >1 tile per cube face

79    
80    checkpoint52i_post
81    o removed CPP_EEOPTIONS.h from verification/*/code
82    o updated the tiling for global_ocean_pressure
83    checkpoint52i_pre
84    
85    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
86      the old pkg/aim).
87    
88    checkpoint52h_pre
89    o shortened offending lines in exch2_send_rx?.template
90    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
91    o genmake2: add build & execute test for NetCDF code
92    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
93      old grid files, moved CPP_EEMACROS.h to pkg/exch2
94    o added useSingleCPUIO flag to monitor.F and mon_out.F
95    o added temporary hack for sea-ice dynamics on the cube:
96      metric terms are ignored and it is assumed that
97      there is no sea-ice on cube faces 1, 2, 4, and 5.
98    
99    checkpoint52f_post
100    o added exch2 cube routines to pkg/exch2

104    
105    checkpoint52e_post
106    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
107      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
108    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
109      to work with implicit vertical advection and AB ;
110    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
111    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
112     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
113    checkpoint52e_pre
114    
115    o fix bug in impldiff when Nr=1 or Nr=2.
116    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
117    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
118    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
119      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure

123    
124    checkpoint52d_post
125    o re-tiled many expts to allow comparison in multi-processor mode
126      - updated output accordingly
127      - changed hs94.128x64x5 to use intial T from file rather than use the
128        random number generator
129    o add infrastructure in model routines for fizhi and gridalt packages
130    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
131    o changes to permit hi-res, cubed-sphere, configuration
132      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
133      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
134      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
135        of surface winds for the cube
136      (A verification experiment, based on global_ocean.cs32x15, but with
137       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
138       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
139       complete with example surface forcing files and matlab scripts to look
140       at the output and compare it with that of global_ocean.cs32x15.)
141    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
142       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
143       to conform to the common rule.
144    o check-in the first version of the coupler + interfaces for multi-components
145       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
146       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
147       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
148       - ocean and atmos. share the same horizontal grid (no interpolation).
149       - exchanges between component and coupler is done in forward_step
150    o new verification experiment, cpl_aim+ocn:
151       coupled ocean - AIM atmosphere on cs32 grid.
152    
153    checkpoint52d_pre
154    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
155    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
156    
157    checkpoint52c_post
158    o Fixing OPTIONS files for use of exf:
159      - ALLOW_ECCO not needed
160      - ECCO_CPPOPTIONS.h should not be included from
161        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
162        as has been the case in the past
163      - All cal/exf related options are currently set in
164        single header file. Should remain so until we
165        agree on a consistent new policy.
166    o Removed all CPP options for cal package.
167      cal has no more CPP options.
168    o modified STOREs in GAD_ADVECTION
169    o corrected key comp. for passkey
170    
171    checkpoint52b_post
172    o new version: "thsice" of thermodynamic sea-ice pkg:
173     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
174     - modify fluxes but do not change theta directly;
175     - light cleaning of bulk_force pkg (still needed with thsice).
176     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
177       + output_thsice.txt to test thsice & bulk_force pkgs.
178    o put back grid & coriolis monitor output.
179    checkpoint52b_pre
180    
181    o call "do_the_model_io" at the beginning (=> dump initial state)
182    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
183    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
184      (need info on NUMBER_OF_PTRACERS)
185    o missing PTRACERS headers in some routines
186    o default tamc.h in pkg/autodiff supposed to crash
187      to ensure proper customization
188    
189    checkpoint52a_post
190    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
191      - moved surfaceTendencyTice from pkg/seaice to main code
192      - subroutine FREEZE_SURFACE now limits only surface temperature
193        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
194        => new output.txt for global_ocean.cs32x15 & global_with_exf
195      - keep the old version of FREEZE for backward compatibility;
196        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

205    o some bug fixes for #undef REAL4_IS_SLOW
206    
207    checkpoint52 = ecco_c52_e35
208    o after testing adjoints of checkpoint51u_post
209    
210    checkpoint51u_post
211    o this is the post-merge tag of the ecco-branch
212      (needs another clean checkout and re-testing)
213    o various natl_box_adjoint configs and results
214      but no input fields
215    o obcs adjoint not yet merged!
216    o adding ECCO global 1x1 and 2x2 degree configs
217    o updated/extended some store directives for seaice
218    o pkg/ecco now containes ecco-specific part of cost function
219    o top level routines the_main_loop, forward_step
220      supersede those in model/src/
221      previous input data.cost now in data.ecco
222      (new namelist ecco_cost_nml)
223    o in ctrl/ cleaned some cross-dependencies and updated CPP options
224    
225    checkpoint51t_post
226    o this is the pre-merge tag of the ecco-branch
227    
228    checkpoint51s_post

230    o pkg/grdchk
231      - renamed 'ph-grd 3' to 'grad-res'
232      - merged from ecco-branch
233        (remaining bug fixes for obcs gradient checks)
234      - additional high-precision output for testreport
235        (grep for 'precision_grdchk_result')
236    
237    checkpoint51r_post
238    o cleaned up or removed CPP_OPTIONS.h files
239    o updated results for some of the tests to reflect the new
240      optfiles (-ieee: -O0 instead of -O3)
241    
242    checkpoint51q_post
243    o cd_code:
244      - moved cd_scheme.F -> cd_code_scheme.F
245      - separate read_checkpoint from cd_code_ini_vars.F
246      - separated cd_code part from write_checkpoint
247      - updated AD_SOURCE, generated .flow
248      - added CD_CODE_VARS.h to the_main_loop
249      - Moving cd_code specific store dir.s to pkg/cd_code
250    o ctrl package totally restructured
251      - pack/unpack now optional and decoupled from
252        xx_/adxx_ I/O
253      - ctrl_pack/unpack cleaned
254        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
255      - confined inclusion of AD_CONFIG.h to where necessary.
256    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
257    
258    checkpoint51p_post
259    o create initial cd_code package
260      - WARNING: the initialization of fields within packages
261        is broken because INI_FIELDS (where READ_CHECKPOINT is
262        called) is called *before* PACKAGES_INIT_VARIABLES.
263        This seems to be backwards since
264        1) its important to initially zero the entire field including
265           the "halo" region
266        2) zeroing needs to be done *before* reading pickup info
267           and the pickup call might or might not happen in any
268           particular run
269      - this needs an overhaul for R2
270    o cleanup verification/*/code/GMREDI_OPTIONS.h
271    o cleanup testreport
272    
273    checkpoint51o_post
274    o bringing AD-related verif's up to date with genmake2

278      - (front_relax/ )
279    o (more) consistent directory structure for AD-related verif.'s
280    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
281    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
282    o bug fix in find_alpha.F for MDJWF:
283      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
284        change rho -> rho-rhoConst
285      - replace call find_rho to find_rhonum
286    o initialisation of rFlx extended to full array (required by TAF)
287      and shifted to thermodynamics
288    o removed PTRACERS.h in ptracers routine
289    o added surfacetendencyPtr to S/R parameter list pracers_forcing
290    o Correcting initialisations for fVerU, fVerV.
291    o helping TAF to recognize dependency on kUp for

304      - moved surfaceTendencyTice from pkg/seaice to main code
305      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
306      - subroutine FREEZE now limits only surface temperature
307        (this means new output.txt for global_ocean.90x40x15,
308         global_ocean.cs32x15, and global_with_exf)
309    o added surface flux output variables to TIMEAVE_STATVARS
310    
311    checkpoint51n_pre
312    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F

332    checkpoint51l_pre
333    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
334    o enable to apply restoring on S & T only in a latitude band.
335    o update output (external_forcing_surf modif. change truncation errors)
336       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
337    
338    checkpoint51k_post
339    o change default to: useNHMTerms=.FALSE.
340     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
341       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5

365    
366    checkpoint51i_post
367    o merge of the branch-genmake2

417    o AIM : add stratospheric drag in the upper level
418    
419    checkpoint51d_post
420    o change function ILNBLNK (=> last non-blank char.) to return zero
421      (instead of the string length) when the string. char is empty
422    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
423    o modif's to restore TAMC compatibility
424      - avoid "_d" constructs in PARAMETER declarations
425      - avoid interrupting lines by comment lines
426    o Use cluster local disks for purely local I/O
427      vs. globally visible disks needed for ctrl stuff
428      (merged from ecco-branch)
429      - new active_file_loc... and mdsio_..._loc routines
430      - affected packages: autodiff, ctrl, grdchk, mdsio
431    
432    checkpoint51c_post
433    o introducing integer flag debugLevel
434      - debLevZero: suppress all output
435      - debLevA: standard
436      - debLevB: equivalent to current debugMode=.TRUE.
437    o introducing pathname variable mdsioLocalDir for mdsio
438      that can be specified at runtime
439      (relevant for cluster I/O to local disk)
440    `
441    >>>checkpoint51b_post
442    adjoint of ptracers
443    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
444    o extended state in checkpoint_lev?, etc.

447    o new ptracers.flow
448    o made ptracers_forcing same as external_forcing_s
449    o added verification for adjoint with ptracers
450      - adm. grdchk fail so far
451      - tlm. grdchk OK
452      - checked tapelev/comlev recomputations: OK
453    <<<checkpoint51b_pre
454    
455    checkpoint51a_post
456    o added code for biogeochemistry package
457      - new pkgs: dic, gchem
458      - new subroutine in ptracers
459    o modify code for biogeo packages
460      - in model/src and pkg/ptracers
461    
462    checkpoint51
463    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
464      - autodiff, ctrl, exf, grdchk, seaice
465      kept separate packages
466      - cost, ecco, obcs
467    o updating verification/internal_wave, verification/lab_sea
468      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
469    
470    checkpoint50i_post
471    o Preparing next differentiable checkpoint and sync
472      of MAIN vs. ecco-branch
473      - 1st step: this one is differentiable
474      - 2nd step: next(! not this) checkpoint will have updated packages
475                  from ecco-branch)
476    
477    checkpoint50h_post
478    o new package "land": provide surface BC for AIM.
479    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
480    o AIM: use true log-P extrapolation for near surface temp (= as in
481        F.Molteni paper) ; update aim.5l_cs output.
482    o New variable in PARM03 for more flexible pickups
483    o somewhat cleaned package initialisation sequence for
484      ctrl/ cost/ ecco/ in packages_... routines
485    
486    checkpoint50g_post
487    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
488      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
489      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
490        made the default because of faster convergence than ADI
491    
492    checkpoint50f_post
493    o exf totally restructured
494      - replaced all exf_set_ routines by one generic exf_set_gen.F
495        and made sure it's still differentiable
496      - split exf_getffields.F into new exf_bulkformulae.F
497      - exf_inscal_/exf_outscal_ suffixes consistent with field names

502          + change Evap over land. (update aim.5l_cs output)
503     o added missing .cvsignores and made uniform across expts
504     o changed configuration of tidal_basin_2d expt
505     o added pkg/debug functions for tracing code in fatal crashes

507     o new fn in pkg/monitor to stop model if solution grows too big
508     o removed lots of single quotes from comments
509    
510    checkpoint50e_post
511    o make KPP work with PTRACERS
512     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
513       nearly a copy of kpp_transport_s
514     - there is no analogue to SurfaceTendencyS, so I have to use
515       gPtr(of the surface layer) instead
516    o add a new platform SunFire+mpi (SunFire 15000) to genmake
517    checkpoint50e_pre
518    
519    checkpoint50d_post
520    o change kpp output from multiple-record state files to single-record state
521      files analogous to write_state.F
522    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
523      analogous to the cg2d-related output.
524    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
525      so that writing to internal file fn (with length 512) fails.
526    checkpoint50d_pre
527    
528    checkpoint50c_post
529    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
530    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
531    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
532    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
533    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
534    
535    checkpoint50c_pre
536    Merging from release1_p13:
537    o bug fix for pkg/seaice dynamic solver
538    o Added SEAICE_initialHEFF to pkg/seaice
539    
540    checkpoint50b_post
541    o store u*,v* in gU,V instead of in guNm1,gvNm1
542    o in order to put the momForcing out of the Adams-Bashforth:
543      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
544      to timestep.F
545    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
546    o re-generate output for highly sensitive test-exp:
547       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
548    
549    checkpoint50b_pre
550    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
551    o corrected CPP option mismatch in exf_Bulk... functions for case
552      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
553    
554    checkpoint50a_post
555    o Bug fix for merging between c50 and KPP.
556      ikey was passed from thermodynamics to kpp_calc via
557      common block rather than being recomputed in kpp_calc,
558      in contradiction with new key itdkey.
559      New key ikppkey created, and tamc.h headers updated.
560    
561    checkpoint50
562    - 2nd step of merge with ecco-branch:
563      merge changes in ecco-branch back into main trunk
564    - bug fix in find_alpha
565    - more storing in gmredi_calc_tensor.F, kpp_routines.F
566    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
567    - merged some sliced AD support routines
568    
569    checkpoint49
570    merged from ecco-branch:
571    o exf:
572      - Enable initialisation of forcing fields to constant
573        (runtime) values.
574      - in exf_getffields.F
575        Reduce i-/j-loop to interior domain, discarding overlaps.
576        That also fixes wrong TAF-key computations for key_1, key_2
577        with bulf formulae.
578      - exf_init.F modify #ifdef for exf_init_evap
579      - exf_getffieldrec.F, ctrl_getrec.F
580        The following INT-usages are not safe:
581          fldsecs  = int(fldsecs/fldperiod)*fldperiod
582          fldcount = int(fldsecs/fldperiod) + 1
583        and were modified.
584    o autodiff: checkpoint_lev...
585      - updated storing for bulk formulae (some arrays were missing)
586      - added state for seaice package
587      - synchronized with main branch
588    o DIVA:
589      Modif.s in
590      - the_main_loop.F
591      - the_model_main.F
592      and added cost_final_restore.F cost_final_store.F
593      o With these changes, it is possible to fully separate
594        the first forward run to compute the cost function (mdthe_main_loop)
595        and adjoint runs over individual DIVA intervals (adthe_main_loop)
596        into separate model executions.
597        This enables better tuning of DIVA to given queue sizes.
598      o Loss of cost function value in consecutive DIVA runs is
599        fixed by storing to 'costfinal' file.
600      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
601        beginning/end of adjoint integration is accounted for.
602      The current changes apply to TAF-1.4.26.
603      TAF has one remaining bug, requiring one manual change
604      (see MITgcm manual).
605    o cal: synchronized between MAIN and ecco-branch
606    
607    checkpoint48i_post
608    o Changes to restore differentiability of code w.r.t. previous tag
609      (mostly adding new routines to make list and replacing
610      pressure by totPhiHyd).
611    o Updated and merged grdchk package
612      - has both ADM and TLM checks
613      - works for single- and multi-proc.
614      - output cleaned
615      - worked successfully for parallel DIVA
616    o genmake:
617      - Adding -platform=SP4
618      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
619    o Modif. for DIVA:
620      ctrl_unpack should not be called in intermediate DIVA interval.
621      (similar thing would apply for active files such as
622      tbar, sbar, psbar, which should not be reinitialised;
623      only relevant for ecco-branch)
624    
625    checkpoint48h_post
626    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
627    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
628    o Added SEAICE_initialHEFF to pkg/seaice
629    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
630    
631    checkpoint48g_post
632    --- EOS:
633    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
634      store total Potential in totPhyHyd for diagnostics & EOS.
635    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
636    --- Pressure/geopotential gradient:
637    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
638    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
639      ( changes results of global_ocean_pressure )
640    o NLFS + z-coord.: add eta*Rho' contribution.
641    o accurate phiHyd when using interface-W at the middle between 2 centers
642     ( changes results of ideal_2D_oce )
643    o includes r* 2nd term in potential gradient.
644    
645    checkpoint48f_post
646    Merging from release1_p12:
647    o Modifications for using pkg/exf with pkg/seaice

650      - units/sign fix for evap computation in exf_getffields.F
651      - updated verification/global_with_exf/results/output.txt
652    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
653      (SBO) core products, including oceanic mass, center-of-mass,
654      angular, and bottom pressure (see pkg/sbo/README.sbo).
655    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
656      to avoid negative values in shallow regions.
657      - updated verification/natl_box/results/output.txt
658      - updated verification/lab_sea/results/output.txt
659    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
660    o Added useSingleCpuIO option (see PARAMS.h).
661    o Updated useSingleCpuIO option in mdsio_writefield.F to
662      work with multi-field files, e.g., for single-file pickup.
663    o pkg/seaice:
664      - bug fix in growth.F: QNET for no shortwave case
665      - added HeffFile for specifying initial sea-ice thickness
666      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
667    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
668      kpp_transport_t.F, forward_step.F, and the_main_loop.F
669    o pkg/seaice:
670      - adjoint-friendly modifications
671      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
672    
673    checkpoint48e_post
674    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
675    o dynamics: change definition of computational domain & adapt mom_fluxform
676      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
677    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
678        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
679        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
680        global_ocean.90x40x15 global_with_exf global_ocean_pressure
681        inverted_barometer solid-body.cs-32x32x1
682      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
683    
684    checkpoint48d_post
685    o in preparation for r*:
686     a) use pre-computed gradient of hydrostatic potential:
687        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
688     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
689        => affects results of glob_oce_pressure (different truncation error)  
690      update output.txt of ideal_2D_oce & global_ocean_pressure
691    
692    checkpoint48d_pre
693    o in preparation for r*:
694      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
695      pass the 2 comp. of the grad. as arguments to momentum S/R.
696      but for the moment, only used if it does not change the results.
697    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
698    
699    checkpoint48c_post
700    Modifications in treatment of initial flux forcing controls
701    to avoid extra storing of flux fields.
702    
703    checkpoint48c_pre
704    o Added tidal_basin_2d experiment (currently 1D!)
705    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
706    
707    checkpoint48b_post
708    o r* coordinate added in #ifdef NONLIN_FRSURF block.
709     (modification to pressure gradient not yet implemented)
710    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
711      (for U & V) that are used for vertical advection of momentum.
712    
713    checkpoint48a_post
714    o In preparation for r*, use temp. array to compute vertical transport
715       in flux-form momentum pkg. => change results of few test-exp.
716      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
717                        lab_sea, natl_box & plume_on_slope
718    
719    checkpoint48
720    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
721    
722    checkpoint47j_post
723    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
724    o moved adexch from forward_step to addummy_in_stepping
725    o added exch in ctrl_map_...
726    o aveFreq.=0. at end of cost_final to avoid overwrite in
727      reverse checkpointing loop
728    o Yet more changes in gmredi:
729      * adgmredi_calc_tensor
730        avoiding all recomputation of gmredi_slope_limit
731      * adgmredi_x/y/rtransport
732        added flag for excessive storing to avoid recomp. of
733        u/v/rtans, dTdx/y/z
734        -> this is not really necessary and very memory-consuming
735      * adgmredi_slope_psi:
736        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
737      * gmredi_slope_limit
738        re-activated full calculation of taperfct for case 'ac02'
739    o updating verification/ adjoints of carbon, global_ocean.90x40x15
740    
741    checkpoint47i_post
742    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
743    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
744      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
745    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
746    o gmredi: fix few bugs.
747    
748    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
749    This will be a good checkpoint to plug into the ecco-branch.
750    o few modif.'s to get latest version adjointed
751      (mainly kick out code in ini_linear_phisurf)
752    o modif's to run adjoint with exactConserv
753    o case GM_BOLUS_ADVEC should be cleaned
754      S/R gmredi_slope_psi should be cleaned
755    o verification/carbon now has exactConserv=.TRUE.
756    
757    checkpoint47g_post
758    o time-average AIM output: becomes independent from statvars time-average
759      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
760    o After TAF bug fix:
761      Tested adjoint of gmredi package.
762      Tests were done with checkpoint47 rather than with latest
763      checkpoint47f_post since the latter is broken for the adjoint
764      verification/carbon/ contains both ADM and TLM gradient checks.
765    Here they are, before they get changed/lost/stolen.
766    Mostly modif.'s to fix numerical sensitivities.
767    Gradient checks OK for
768    - GM_taper_scheme:
769      * clipping
770      * ac02
771      * linear
772      * glw91
773      * dm95
774      * ldd97
775    - GMREDI_OPTIONS:
776      * GM_VISBECK_VARIABLE_K
777      * GM_NON_UNITY_DIAGONAL
778      * GM_EXTRA_DIAGONAL
779      * GM_BOLUS_ADVEC
780    in conjunction with data.gmredi parameters to be checked in
781    in a few minutes under verification/carbon/code/
782    
783    checkpoint47f_post
784    Merging from release1_p10:
785    o modifications for using pkg/exf with pkg/seaice
786      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
787        and SEAICE_EXTERNAL_FLUXES
788      - pkg/exf CPP options EXF_READ_EVAP and
789        EXF_NO_BULK_COMPUTATIONS
790      - usage examples are Experiments 8 and 9 in
791        verification/lab_sea/README
792      - verification/lab_sea default experiment now uses
793        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
794    
795    checkpoint47e_post
796    o created a tag prior to creating a branch
797    
798    checkpoint47d_post
799    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
800      at the bottom boundary had an erroneous half slip boundary condition
801    o added bottom drag and no slip boundary condition capabilities to
802      oceanic pressure coordinates code
803    o added new verification experiment global_ocean_pressure, this experiment is
804      also described in the tutorial section of the manual
805    checkpoint47d_pre
806    
807    checkpoint47c_post
808    o Added a verification experiment for a global cubed-sphere ocean run
809      -  verification/global_ocean.cubed32x32x30
810      -  uses pkg/therm_seaice and pkg/bulk_forcing
811    
812    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
813    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
814      when using P-coordinate; only implemented for atmospheric config.
815    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
816      NOTES: requires option NONLIN_FRSURF to be "#define".
817    o update advect_xz/results/output.txt (left from checkpoint44g_post)
818    
819    checkpoint47b_post
820    Merging from release1_p9:
821    o pkg/seaice
822      - removed GOTO's and added taf directives
823      - double precision constants to reduce the g77 (Linux)
824        to F77 (SGI) differences reported in release1_p8
825    o tools/genmake
826      - added SGI options
827    o verification/testscript
828      - updated to that of checkpoint47a_post
829    o verification/global_ocean.90x40x15/input/eedata
830      - modified for SGI f77 compatibility
831    o verification/lab_sea
832      - added description of sea-ice model
833      - added missing matlab routines
834      - added test of thermodynamics parallelization
835    
836    checkpoint47a_post
837    o new pkg: aim_v23
838     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
839       for now, keep the same surface forcing as before.
840     - Part-Cell implemented into AIM; check that Heat & Water are conserved
841     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
842     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
843    o add diagnostic of surface correction term in monitor output
844    
845    o bulk_force and therm_seaice
846    - Two packages:  bulk_force (Bulk forcing)
847      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
848    - Earlier integration from Stephaine Dutkiewicz
849      and Patrick Heimbach.
850    - Two ifdef statements for compile time,
851       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
852    
853    checkpoint47
854    differentiable version of checkpoint46n_post
855    o bug fix in quasihydrostaticterms
856    o * "clean" adjoint code (in terms of extensive recomputations)
857        can now be obtained for all GMREDI options (i.e. for
858        - GM_VISBECK_VARIABLE_K
859        - GM_NON_UNITY_DIAGONAL
860        - GM_EXTRA_DIAGONAL
861        - GM_BOLUS_ADVEC )
862      * However, wrong gradient check problem remains unsolved.
863      * New CPP options have been introduced for different
864        tapering schemes
865    o external_fields_load now part of differentiation list
866    o pressure needs multiple storing;
867      would be nice to have store_pressure at beginning or
868      end of forward_step, e.g. by having phiHyd global (5-dim.)
869      (NB: pressure is needed for certain cases in find_rho,
870      which is also invoked through convective_adjustment).
871    o recomputations in find_rho for cases
872     'JMD95'/'UNESCO' or 'MDJWF' are OK.
873    o #define ATMOSPHERIC_LOADING should be differentiable
874    o ini_forcing shifted to begining of initialise_varia
875    o Incorporating QNVS line search routines into MITgcm
876      (this is separate code, and therefore not under pkg)
877      lsopt/, optim/
878    o Updated verification/carbon/
879      - #define GM_VISBECK_VARIABLE_K
880      - GM_taper_scheme    = 'ldd97'    
881    
882    checkpoint46n_post
883    Merging from release1_p8:
884    o verification/natl_box:
885      updating new external_fields_load routine
886    o New package: pkg/seaice
887      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
888      The sea-ice code is based on Hibler (1979-1980).
889      Two sea-ice dynamic solvers, ADI and LSR, are included.
890      In addition to computing prognostic sea-ice variables and diagnosing
891      the forcing/external data fields that drive the ocean model,
892      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
893      The implied surface heat flux is then stored in variable
894      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
895      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
896      non-local transport term.  Because this call precedes model
897      thermodynamics, temperature under sea-ice may not be "exactly" at
898      the freezing point by the time theta is dumped or time-averaged.
899      N.B.: fairly large differences in accuracy occur across
900            different platforms/compilers; comparison between
901            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
902            generated output gives:
903       T           S           U           V
904      C D M    c        m  s        m  s        m  s        m  s

908    
909      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
910    o GAD:
911      - generated new common blocks to account for call of
912        same gad routines with differing traceridentities
913        (needed to modify tracerIdentity indices in GAD.h)
914      - generated separate common blocks for case useCubedSphereExchange
915        (Department of Futurology)
916      - parameter lists to gmredi_?transport: added tracerIdentity
917      - added new key indices to tamc.h
918    o external_fields_load:
919      - added this routine to TAF list
920      - needed to make some common blocks global and additional storing
921        along the same lines as exf package (checkpoint_lev?_directives.h)
922    o exf:
923      updated external forcing package
924      - bug fixes carried over from ecco-branch
925        (missing OBCS_OPTIONS.h in two routines)
926      - enable easy to use "no forcing".
927      - added exf I/O for atmospheric loading
928      - added exf I/O for runoff data
929      - transfered scaling between exf <-> MITgcm to exf namelist
930    o Adding new verification experiment global_with_exf.
931      This verification experiment is almost identical to the
932      global_ocean.90x40x15 experiment, except that it uses
933      the exf (and cal) package instead of the
934      external_fields_load routine (cf README file).
935    
936    checkpoint46m_post
937    o modified testscript to return -- when there are no lines of "%MON" output
938    o added new flag "quasiHydrostatic" for QH mode
939      and new routine quasihydrostaticterms()
940    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
941      New routine: mom_u_coriolis_nh()
942    o fixed sign of non-hydrostatic metric terms in u and v equations.
943      Depend on correct sign of gravitySign.
944    o added work.pc* to .cvsignore in aim directories using ifc
945    o introduced flag for controllin non-hydrostatic metric terms
946    o removed gravitySign from PARM04
947    o switched to g77/ifc from pgf77 in aim experiments
948    
949    checkpoint46l_post
950    o made convective adjustment work with pressure coordinates:
951     - changed the direction of k-loop in convective_adjustment.F for the
952       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
953     - adjusted the reference pressure k-index in convective_adjustment.F
954     - adjusted the convection condition in convect.F (in analogy to
955       calc_ivdc.F)
956     - convective_adjustment no longer computes anything on the halos
957     - removed the warnings about negative salinity from find_rho.F and
958       find_alpha.F; instead the new routine look_for_neg_salinity, called
959       at the beginning of find_rho, find_alpha, and find_beta, does a
960       check of the entire slice, if CPP-option
961       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
962    checkpoint46l_pre
963    
964    checkpoint46k_post
965    o fixed the verification/global_ocean.90x40x15 experiment:
966     - new bathymetry (the world according to A., JMC, and M.)
967     - new initial fields and forcing fields (*.bin files)
968     - new POLY3.COEFFS (for the next release one should switch to a full
969       equation of state: JMD95P or MDJWF)
970     - fixed several errors and redundancies in the data file
971     - experiment uses looped cells
972     - added matlab directory with diagnostic scripts for plotting of output
973    
974    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
975     - read AIM physics parameters from a file (data.aimphys)
976     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
977    
978    checkpoint46j_post
979    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
980    o move wVel computation at the end of the time step, in S/R integr_continuity
981    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
982    o update timeave pkg for wVel diagnostic.
983    checkpoint46j_pre
984    
985    checkpoint46i_post
986    o Clean up AIM package (and keep the results unchanged):
987      include CPP_OPTION and use IMPLICT NONE in all routines ;
988      declare all the variables _RL ; use _d 0 for all numerical constants.
989      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
990    
991    checkpoint46h_post
992    o cleaned up the use of rhoNil and rhoConst.
993      - rhoNil should only appear in the LINEAR equation of state, everywhere
994        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
995        and the dynamical equations are all divided by rhoConst
996    o introduced new parameter rhoConstFresh, a reference density of fresh
997      water, to remove the fresh water flux's dependence on rhoNil. The default
998      value is 999.8 kg/m^3
999    o cleanup up external_forcing.F and external_forcing_surf.F
1000      - can now be used by both OCEANIC and OCEANICP
1001    checkpoint46h_pre
1002    
1003     Added code to convert surface volume flux (fresh water) into
1004     a mass flux when using P coordinates in the ocean (OCEANICP).
1005     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1006    
1007    checkpoint46g_post
1008    o Include a new diagnostic variable phiHydLow for the ocean model
1009      - in z-coordinates, it is the bottom pressure anomaly
1010      - in p-coordinates, it is the sea surface elevation
1011      - in both cases, these variable have global drift, reflecting the mass
1012        drift in z-coordinates and the volume drift in p-coordinates
1013      - included time averaging for phiHydLow, be aware of the drift!
1014    o depth-dependent computation of Bo_surf for pressure coordinates
1015      in the ocean (buoyancyRelation='OCEANICP')
1016      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1017        Theta, Salinity, and Pressure in the parameter list. This routine is
1018        presently contained in find_rho.F. This routine does not give the
1019        correct density for 'POLY3', which would be a z-dependent reference
1020        density.
1021    o cleaned up find_rho
1022      - removed obsolete 'eqn' from the parameter list.
1023    o added two new verification experiments: gop and goz
1024      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1025    checkpoint46g_pre
1026    
1027    checkpoint46f_post
1028    o Enable tangent linear (forward mode) gradient checks:
1029      - extended active file handling to g_... files
1030      - added TANGENT_SIMULATION to theSimulationMode
1031      - extended grdchk package accordingly
1032    o added tangent linear setup in verification/carbon/code_ftl
1033    o added adjoint setup in verification/front_relax/code_ad
1034    
1035    checkpoint46e_post
1036    o Added new equation of state -> MDJWF
1037      - EOS of McDougall et al., 2002, JAOT, submitted
1038      - caveat: the equation of state is only valid for a smaller (more
1039        realistic?) range of values than JMD95P/Z and UNESCO
1040      - added masks to the calculation of pressure in store_pressure
1041      - added more check values for density in check_eos (ini_eos.F), some of
1042        the old check values are out of the range of the MDJWF-eos, so don't
1043        expect perfect matches for those
1044    checkpoint46e_pre
1045    
1046    checkpoint46d_post
1047    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1048      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1049      case of pressure coordinates. eosType='JMD95Z' in
1050      combination with buoyancyRelation='OCEANICP' now causes an error.
1051    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1052      in find_alpha/beta.
1053    checkpoint46d_pre
1054    
1055    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1056      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1057    
1058    checkpoint46c_post
1059    o Changes necessary for ocean in p-coordinates
1060     -  Added new buoyancy relation = 'OCEANICP'
1061     -  Added new parameters = gravitySign (this used to be contained inside
1062        the factor dRdZ which I added when we first switched to R coordinates).
1063     X GM/Redi is not compatible (yet)
1064     X bottom drag and no-slip need to be debugged.
1065    checkpoint46c_pre
1066    
1067    checkpoint46b_post
1068    o Added new equation of state -> JMD95Z and JMD95P
1069      - EOS of Jackett and McDougall, 1995, JAOT
1070      - moved all EOS parameters into EOS.h
1071      - new routines ini_eos.F, store_pressure.F
1072    o Added UNESCO EOS, but not recommended because it requires
1073      in-situ temperature (see JMD95)
1074    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1075      unesco.f to be used with POLY3
1076    checkpoint46b_pre
1077    
1078    checkpoint46a_post
1079    o Added (atmospheric) pressure loading
1080      - new field in FFIELDS.h, etc...
1081      - new cpp flag ATMOSPHERIC_LOADING
1082    o Changed hFacC to _hFacC in calc_phi_hyd.F
1083    o Added SHORTWAVE_HEATING to some files for consistency
1084    checkpoint46a_pre
1085    
1086    checkpoint46
1087    further merges from release1_p5
1088    o new ctrl package
1089      - adopted from ECCO environment to enable optimization
1090      - added Eliassen Palm fluxes to controls
1091    o added Eliassen Palm flux controls to gradient check package
1092    o cost package
1093      - Compatible with new ctrl package
1094      - added Eliassen Palm cost hooks
1095      - modif's of existing cost functions
1096    o Adjoint-related bug fixes in kpp:
1097      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1098      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1099    o autodiff package
1100      - flow directives:
1101        + new for S/R do_the_model_io
1102        + enhanced for S/R checkpoint
1103        + new gmredi.flow
1104      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1105        disable adcommon.h/g_common.h by default.
1106      - fixed problem for adjoint of global_max
1107    o modified verification/carbon/
1108    o New setup for adjoint of global_ocean
1109    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1110    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1111    o incorporated hooks for sponge layer code (external_forcing.F)
1112    
1113    checkpoint45d_post
1114    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1115    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1116      (affects plume_on_slope "cg2d" output)
1117    o add new parameter deltaTfreesurf for free-surface time stepping
1118    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1119    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1120    o change phiMin in exp1 (to agree with documentation)
1121    o add new flags:
1122     - T,S forcing inside/outside Adams-Bashforth
1123     - turn off temp,salt advection and/or forcing
1124     - for each tracer, define internal flag for multiDimAdvection & A-B
1125    o monitor: change definition of KE to check conservation of Energy
1126    
1127    checkpoint45c_post
1128    o Removed f90 comments ("!")
1129    o Modified initialisations to enable exf package for MITgcm
1130      (without invoking ECCO_PACKAGE).
1131    o modifications to gradient check package (Martin Losch)
1132      - enable centered differences
1133      - modified format of standard output
1134    
1135    checkpoint45b_post
1136    o cleaned exchange calls in cg2d
1137    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1138    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1139      to configure barotropic setup (Martin Losch)
1140    o moved some initialisations within bi,bj loop in dynamics
1141      (TAF flow dependency)
1142    o in initialise_varia, moved call packages_init_variables
1143      before convective_adjustment_init
1144      (corresponding adjustment of TAF tape initialisation).
1145    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1146    
1147    checkpoint45a_post
1148    o compute Rho over the whole domain (extend iMin,jMin indices)
1149    o specific exchange for X-slice domain (case Ny=1)
1150    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1151    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1152    
1153    checkpoint44h_post = checkpoint45
1154    o Fix to restore differentiability:
1155      place at which packages_init_variables is called in
1156      initialise_varia is crucial for reverse control flow.
1157    o modifications in GMRedi to enable stable adjoint
1158      (corresponding modif's in thermodynamics, dynamics)
1159    o added missing hook for sponge layer code in external_forcing
1160    o modified test cost functions
1161    o storing in gad_advection (plus removal of write(0,*)!
1162    o missing headers TR1.h added in convective_adjustment routines
1163    o errorMessageUnit set non-equal zero in eeboot
1164      (conflict on some platforms, e.g. IBM SP3)
1165    o modified carbon verif.
1166    
1167    checkpoint44h_pre
1168    o vertical grid option: allow to put the Interface at the middle between
1169      2 cell-centers ; replace delZ in pkg/kpp by drF.
1170    o GM Advective form: Tracers are advected using the residual transport (=
1171      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1172    
1173    checkpoint44g_post
1174    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1175      results) ; ifdef missing in thermodynamics.F
1176    
1177    checkpoint44f_pre,checkpoint44f_post
1178    o added PTRACERS package
1179      This allows an arbitrary number of passive tracers to be integrated
1180      forward simultaneously with the dynamicaly model.
1181      + Implemented so far:
1182        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1183        - I/O and checkpointing
1184        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1185      + Not implemented so far:
1186        - KPP
1187        - OBCS
1188      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1189        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1190        line in data.pkg.
1191      + This package is disabled by default since it increases storage.
1192    
1193    
1194    o testscript: added -cleanup option
1195    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
1196                 b) enable to filter 2D fields.
1197    
1198    checkpoint44e_pre,post
1199    o re-wrote convective adjustment to use pre-calculated weights
1200      Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
1201      Adds:    model/src/convective_weights.F, convectively_mixtracer.F
1202      Original calls to convect() still in place.
1203    
1204    chkpt44d_pre,post
1205    o added missing EXCLUDE_MONITOR flags
1206    o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
1207      (incompatible typ in MIN/MAX expressions caused problems
1208      on IBM SP3)
1209    o in genmake added variable MAKEDEPEND
1210      plus resetting for case SunOS
1211    o added timer_stats.c routine for IBM SP3
1212    o removed variables in dynamics
1213    !!! I forgot to create tag chkpt44d_pre !!!
1214    !!! But chkpt44d_pre = chkpt44c_post    !!!
1215    
1216    o real fresh water flux implemented with non-linear free-surface.
1217    
1218    chkpt44c_pre,post
1219    o few fix (mask in shap_s2, EmPmR in external_field_load,
1220      USE_NATURAL_BCS in solve_for_P);
1221    o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
1222    
1223    checkpoint44b_pre/_post
1224    o merge of relevant stuff from the ecco-branch:
1225      - genmake: removed $S64 overwrite for case SunOS
1226      - pkg/exf: update and corrections for field swapping and obcs
1227      - pkg/ecco: parameter lists for the_model_main, the_main_loop

1286      
1287    checkpoint40pre8
1288    o new package rw/
1289      Added method for dumping intermediate local arrays:
1290      mdsio_writetile - same as mdsio_writefield except works from inside
1291                        bi,bj loop
1292      mdsio_writelocal - same as mdsio_writetile except works for local
1293                         arrays
1294      write_local_r? - higher-level wrapper for mdsio_writelocal
1295      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1296      Example given at end of mom_vecinv.F that dumps some local arrays.
1297    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1298      control flux-form versus vector invariant code.
1299      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1300      or genmake -DISABLE ...
1301    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1302      (additional storing is now needed for case vecinv;
1303      currently nothing implemented to switch this storing off
1304      in case fluxform is used since no CPP flag available).
1305    
1306    checkpoint40pre7
1307    o bug fix in dynamics.F
1308      calc_viscosity called before k=1,Nr loop.

1314    o split dynamics into thermodynamics & dynamics
1315    o corresponding split of calc_diffusivity into
1316      calc_diffusivity, calc_viscosity
1317      (kpp_calc_diff, kpp_calc_visc).
1318    o Added diffkr, kapgm to control variables
1319    o bug fix in gmredi_slope_limit for ldd97
1320    
1321    checkpoint40pre5
1322    o proper initialization of Adams-Bashforth time stepping
1323      + uses forward step for very first step of model (iter=0)
1324    o re-generated *all* output since almost all output is modified by this
1325      change (sorry but we've been putting this one off for about 2 years)
1326      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1327        *not* regenerated since they are already out of date and I don't
1328        want to create the impression that they are suddenly working.
1329    o removed KAP stuff for DEC's
1330    o modified/added many .cvsignore files in */code and */input
1331    o added new expt "solid-body.cs-32x32x1"
1332      + this uses an alternative form of ini_curvilinear_grid.F which
1333        is not necessarily any better than the current one...
1334    
1335    checkpoint40pre4
1336    o added re-initialisations of utrans,vtrans,rtrans in
1337      calc_common_factors which are crucial for TAF.

1347    
1348    checkpoint40pre2
1349    o Updated to latest branch of AJA, JMC
1350    o Added gradient check package
1351    o Added routines for passive tracer handling
1352    o Added carbon sequestration sensitivity experiment
1353    
1354    checkpoint39
1355     o Modifications and fixes to support TAMC
1356       (mainly missing or wrong directives)
1357     o Corrected common blocks when fooling TAMC to produce adjoint I/O
1358       in addummy_in_stepping
1359     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1360     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1361     o Included following packages:
1362       cal: calendar
1363       exf: external forcing
1364       ecco: essential routines to control use of cal, exf
1365             (NB: this is not the full ECCO environment)
1366     o disabled some packages by default in genmake
1367    
1368  checkpoint38  checkpoint38
1369   o see notes_c37_adj.txt   o see notes_c37_adj.txt
1370   o corrected wrong layer index in external_forcing_t   o corrected wrong layer index in external_forcing_t
