3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o bug fix in exf-package:
7      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
8         now reflect that.
9    o small fixes in the cal-package:
10      - set reference date to first of January for the 'model'-calendar
11      - failing of cal_CheckDate in cal_FullDate now actually results in a
12        warning
13    o small modifications in exf-package to increase flexibility:
14      - change climtempfreeze from a constant to a runtime parameter that
15        is specified in data.exf_clim (default = -1.9)
16      - introduce runtime parameter windstressmax (default = 2.0) that is
17        specified in data.exf
18    o fix in pkg/thsice:
19      - update Evap (Tsf changes) to be consistent with Latent heat flux
20      - maintain snow precipitation unchanged (even if Tsf >=0).
21     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
22    
23    checkpoint52m_post
24    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
25      this does not change any of the results, because myIter=0 in swfrac always
26      lead to jwtype=2 (the default anyway), but the call makes little sense
27      as a default
28    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
29    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
30      atmospheric model (AIM) to use it ; add a "slab ocean" component.
31    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
32    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
33    o extending useSingleCpuIO option to work with new exch2 I/O format
34      - old-style, missing-tile I/O is still accessible by defining CPP
35        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
36    o monitor package can write to NetCDF files and/or STDOUT
37    o fix re-definition bug in MNC_GRID_INIT_ALL()
38    o doc/api_reference added
39      - a framework for building an API Reference Manual using all
40        the "protex" comments embedded in the code
41      - see pkg/generic_advdiff, pkg/mnc for examples
42    o MNC:
43      - make myThid the last argument for all subroutines
44      - new default for the grid files: NO halos
45      - add useMNC and other run-time flags
46      - separate per-file-group handling of the unlimited dimension
47      - early initialization of MNC w/ flags read at the eeboot stage
48        and lookup tables set in initialize_fixed
49      - write all MNC output to a freshly-created directory
50    o thermodynamics sea-ice (thsice) is now tested with testreport.
51    o test exp. advect_cs: use the standard cs32 grid ; update output.
52    o Added functionality to grdchk:
53      pick global i,j,k position (or nearest wet) where to perform check.
54    
55    checkpoint52l_post
56    o new land formulation:
57      a) use ground enthalpy as prognostic variable to ensure exact
58         energy conservation.
59      b) account for water temperature and for latent heat of freezing
60         in all processes (rain, run-off, ground storage)
61      c) compute surface and ground temperature implicitly.
62    o aim_v23 modification for new land model:
63      a) Treat separately land / ocean / sea-ice surface fluxes
64         to allow implicit computation of land & sea-ice surface temp.
65      b) add snow precipitation.
66    checkpoint52l_pre
67    
68    o fix problem (when 1 tile is empty) in min/max monitor.
69    o fix bug in timeAve (u,vZetatave in common block)
70    o no restoring terms under ice for pkg/seaice
71    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
72    o bug fix for pkg/seaice pickups
73    o change MNC call locations and add coordinate attributes
74    o mask vorticity at the corner ; affects global_ocean.cs output
75    o fix ini_curvilinear_grid ; test CS experiments with mpi
76    o aim.5l_cs: modify sea-ice fraction input file ; update output
77    o exf: Adding simple range check routine for exf fields after read
78    
79    checkpoint52k_post
80    o removed top-level directory "diags"
81      - we migrated these functions to pkg/timeave a long time ago
82    o fixed bug introduced in pkg/monitor
83    o accuracy ctrlprec = 32 insuffient for gradient checks using
84      averaged fields (I/O via cost_averages)
85      -> use ctrl.h in active_file*.F to control I/O precision.
86    o paramter list of CALL ADTHE_MAIN_LOOP
87    o added initial do_the_model_io to ecco
88    o set all ...Freq to zero after cost_final
89      taveFreq, dumpFreq, pChkptFreq
90    o MAIN and ECCO differentiability restored
91    
92    checkpoint52j_post
93    o fix nchklev in tamc.h for global_ocean...
94    o Bringing flow and store directives up-to-date
95    o Really weird thing!
96      call do_the_model_io from the_main_loop with parameters
97      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
98      TAF places a faulty re-call of initialise_varia
99      after cost_final call which should not be there!
100    checkpoint52j_pre
101    
102    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
103      error messages
104    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
105    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
106      debug output
107    o modfied mdsio_writefield.F to handle non-global files under exch2
108    o update AIM Cubed-Sphere exp (aim.5l_cs):
109      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
110    o update AIM Equatorial Channel exp:
111      use standard aim_v23 pkg and change the SST fields to be more realistic.
112    o globalFile now works with exch2
113    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
114      mon_vort3.F to make exch2 friendly with >1 tile per cube face
115    o limit timeave output for hi-res integrations
116    
117    checkpoint52i_post
118    o removed CPP_EEOPTIONS.h from verification/*/code
119    o updated the tiling for global_ocean_pressure
120    checkpoint52i_pre
121    
122    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
123      the old pkg/aim).
124    
125    checkpoint52h_pre
126    o shortened offending lines in exch2_send_rx?.template
127    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
128    o genmake2: add build & execute test for NetCDF code
129    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
130      old grid files, moved CPP_EEMACROS.h to pkg/exch2
131    o added useSingleCPUIO flag to monitor.F and mon_out.F
132    o added temporary hack for sea-ice dynamics on the cube:
133      metric terms are ignored and it is assumed that
134      there is no sea-ice on cube faces 1, 2, 4, and 5.
135    
136    checkpoint52f_post
137    o added exch2 cube routines to pkg/exch2
138    o modified hs94.cs-32x32x5 to use it
139    o added new grid files to hs94.cs-32x32x5
140    checkpoint52f_pre
141    
142    checkpoint52e_post
143    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
144      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
145    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
146      to work with implicit vertical advection and AB ;
147    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
148    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
149     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
150    checkpoint52e_pre
151    
152    o fix bug in impldiff when Nr=1 or Nr=2.
153    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
154    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
155    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
156      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
157    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
158    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
159    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
160    
161    checkpoint52d_post
162    o re-tiled many expts to allow comparison in multi-processor mode
163      - updated output accordingly
164      - changed hs94.128x64x5 to use intial T from file rather than use the
165        random number generator
166    o add infrastructure in model routines for fizhi and gridalt packages
167    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
168    o changes to permit hi-res, cubed-sphere, configuration
169      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
170      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
171      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
172        of surface winds for the cube
173      (A verification experiment, based on global_ocean.cs32x15, but with
174       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
175       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
176       complete with example surface forcing files and matlab scripts to look
177       at the output and compare it with that of global_ocean.cs32x15.)
178    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
179       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
180       to conform to the common rule.
181    o check-in the first version of the coupler + interfaces for multi-components
182       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
183       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
184       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
185       - ocean and atmos. share the same horizontal grid (no interpolation).
186       - exchanges between component and coupler is done in forward_step
187    o new verification experiment, cpl_aim+ocn:
188       coupled ocean - AIM atmosphere on cs32 grid.
189    
190    checkpoint52d_pre
191    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
192    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
193    
194    checkpoint52c_post
195    o Fixing OPTIONS files for use of exf:
196      - ALLOW_ECCO not needed
197      - ECCO_CPPOPTIONS.h should not be included from
198        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
199        as has been the case in the past
200      - All cal/exf related options are currently set in
201        single header file. Should remain so until we
202        agree on a consistent new policy.
203    o Removed all CPP options for cal package.
204      cal has no more CPP options.
205    o modified STOREs in GAD_ADVECTION
206    o corrected key comp. for passkey
207    
208    checkpoint52b_post
209    o new version: "thsice" of thermodynamic sea-ice pkg:
210     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
211     - modify fluxes but do not change theta directly;
212     - light cleaning of bulk_force pkg (still needed with thsice).
213     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
214       + output_thsice.txt to test thsice & bulk_force pkgs.
215    o put back grid & coriolis monitor output.
216    checkpoint52b_pre
217    
218    o call "do_the_model_io" at the beginning (=> dump initial state)
219    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
220    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
221      (need info on NUMBER_OF_PTRACERS)
222    o missing PTRACERS headers in some routines
223    o default tamc.h in pkg/autodiff supposed to crash
224      to ensure proper customization
225    
226    checkpoint52a_post
227    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
228      - moved surfaceTendencyTice from pkg/seaice to main code
229      - subroutine FREEZE_SURFACE now limits only surface temperature
230        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
231        => new output.txt for global_ocean.cs32x15 & global_with_exf
232      - keep the old version of FREEZE for backward compatibility;
233        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
234      - corresponding modifs for TAF directives
235    o added surface flux output variables to TIMEAVE_STATVARS
236    o time-averaged output for pkg/ptracers
237    o fix problem with ECCO-related divided adjoint
238      snapshot file was missing some ad-variables,
239      but no warning issued by TAF
240    
241    checkpoint52a_pre
242    o some bug fixes for #undef REAL4_IS_SLOW
243    
244    checkpoint52 = ecco_c52_e35
245    o after testing adjoints of checkpoint51u_post
246    
247    checkpoint51u_post
248    o this is the post-merge tag of the ecco-branch
249      (needs another clean checkout and re-testing)
250    o various natl_box_adjoint configs and results
251      but no input fields
252    o obcs adjoint not yet merged!
253    o adding ECCO global 1x1 and 2x2 degree configs
254    o updated/extended some store directives for seaice
255    o pkg/ecco now containes ecco-specific part of cost function
256    o top level routines the_main_loop, forward_step
257      supersede those in model/src/
258      previous input data.cost now in data.ecco
259      (new namelist ecco_cost_nml)
260    o in ctrl/ cleaned some cross-dependencies and updated CPP options
261    
262    checkpoint51t_post
263    o this is the pre-merge tag of the ecco-branch
264    
265    checkpoint51s_post
266    o cleanup: removed various obsolete #define-s
267    o pkg/grdchk
268      - renamed 'ph-grd 3' to 'grad-res'
269      - merged from ecco-branch
270        (remaining bug fixes for obcs gradient checks)
271      - additional high-precision output for testreport
272        (grep for 'precision_grdchk_result')
273    
274    checkpoint51r_post
275    o cleaned up or removed CPP_OPTIONS.h files
276    o updated results for some of the tests to reflect the new
277      optfiles (-ieee: -O0 instead of -O3)
278    
279    checkpoint51q_post
280    o cd_code:
281      - moved cd_scheme.F -> cd_code_scheme.F
282      - separate read_checkpoint from cd_code_ini_vars.F
283      - separated cd_code part from write_checkpoint
284      - updated AD_SOURCE, generated .flow
285      - added CD_CODE_VARS.h to the_main_loop
286      - Moving cd_code specific store dir.s to pkg/cd_code
287    o ctrl package totally restructured
288      - pack/unpack now optional and decoupled from
289        xx_/adxx_ I/O
290      - ctrl_pack/unpack cleaned
291        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
292      - confined inclusion of AD_CONFIG.h to where necessary.
293    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
294    
295    checkpoint51p_post
296    o create initial cd_code package
297      - WARNING: the initialization of fields within packages
298        is broken because INI_FIELDS (where READ_CHECKPOINT is
299        called) is called *before* PACKAGES_INIT_VARIABLES.
300        This seems to be backwards since
301        1) its important to initially zero the entire field including
302           the "halo" region
303        2) zeroing needs to be done *before* reading pickup info
304           and the pickup call might or might not happen in any
305           particular run
306      - this needs an overhaul for R2
307    o cleanup verification/*/code/GMREDI_OPTIONS.h
308    o cleanup testreport
309    
310    checkpoint51o_post
311    o bringing AD-related verif's up to date with genmake2
312      - carbon/
313      - global_ocean.90x40x15/
314      - hs.94.1x64x5/
315      - (front_relax/ )
316    o (more) consistent directory structure for AD-related verif.'s
317    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
318    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
319    o bug fix in find_alpha.F for MDJWF:
320      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
321        change rho -> rho-rhoConst
322      - replace call find_rho to find_rhonum
323    o initialisation of rFlx extended to full array (required by TAF)
324      and shifted to thermodynamics
325    o removed PTRACERS.h in ptracers routine
326    o added surfacetendencyPtr to S/R parameter list pracers_forcing
327    o Correcting initialisations for fVerU, fVerV.
328    o helping TAF to recognize dependency on kUp for
329      fVerU, fVerV
330    o Replacing delZ by delR in pkg/ctrl/
331    checkpoint51o_pre
332    
333    o undid all of cp51 pending some cleanups and discussion
334    o added the [#include "AD_CONFIG.h"] statement to all files that need
335       it for adjoint/tl #defines
336     o re-worked the build logic in genmake2 to support AD_CONFIG.h
337     o removed tools/genmake since it no longer works
338    
339    checkpoint51n_post
340    o modifications to make FREEZE flux visible to pkg/kpp
341      - moved surfaceTendencyTice from pkg/seaice to main code
342      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
343      - subroutine FREEZE now limits only surface temperature
344        (this means new output.txt for global_ocean.90x40x15,
345         global_ocean.cs32x15, and global_with_exf)
346    o added surface flux output variables to TIMEAVE_STATVARS
347    
348    checkpoint51n_pre
349    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
350    o added [#include "AD_CONFIG.h"] to all files that use the following
351      defines:
352      - ALLOW_ADJOINT_RUN
353      - ALLOW_TANGENTLINEAR_RUN
354      - ALLOW_ECCO_OPTIMIZATION
355    
356    checkpoint51m_post
357    o incorporating changes to get TAMC/TAF working in genmake2
358      - added new TAMC/TAF targets to the Makefile
359      - various cleanups related to package handling
360      - these changes should have no impact on the forward model
361    
362    checkpoint51l_post
363    o changes to pkg/cal and pkg/exf that allow and speed-up long integrations
364     - faster algorithm for cal_addtime.F
365     - higher precision arithmetic, where needed
366     - pkg/exf *startdate variables changed from calendar date to
367       model integration time
368    
369    checkpoint51l_pre
370    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
371    o enable to apply restoring on S & T only in a latitude band.
372    o update output (external_forcing_surf modif. change truncation errors)
373       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
374    
375    checkpoint51k_post
376    o change default to: useNHMTerms=.FALSE.
377     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
378       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5
379     - new output.txt for idealized oceanic exp (NHMTerms are now turned off):
380        exp1, ideal_2D_oce
381     - change data file of oceanic exp (leave the results unchanged for now)
382       exp2, global_ocean[90x40x15,pressure,with_exf], lab_sea, natl_box
383    o set gravitySign automatically according to the vertical coordinate used
384      (and change sign: back to "logical" value: +1 when R increases downward)
385    o added an include barrier to the default CPP_OPTIONS.h and
386      removed the #include "PACKAGES_CONFIG.h" from it
387    o fix a bug in mom_fluxform (from chk51j_post)

392    o added cubed-sphere case to test cost function
393    o heckpoint_lev?_directives.h now include
394      pkg-specific directives, whenever those are enabled.
395    o Moving pkg-specific flow directives to corresponding pkg
396      Moving pkg-specific differentiation list to corresponding pkg
397      Moving pkg-specific checkpoint-lev storing to corresponding pkg
398      ---> conventions are
399           - pkg_ad.flow
400           - pkg_ad_diff.list
401           - pkg_ad_check_lev?_dir.h
402    
403    checkpoint51i_post
404    o merge of the branch-genmake2

433    
434    checkpoint51f_pre
435    o Added on-the-fly spatial interpolation capability
436        "USE_EXF_INTERPOLATION" to pkg/exf.
437      - This is a temporary Cartesian-grid hack until
438        the super-duper ESMF coupler becomes available.
439      - See verification/global_with_exf/README for usage example.
440      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
441        flags and modified pkg/seaice accordingly.
442    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,

459    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
460    o modif's to restore TAMC compatibility
461      - avoid "_d" constructs in PARAMETER declarations
462      - avoid interrupting lines by comment lines
463    o Use cluster local disks for purely local I/O
464      vs. globally visible disks needed for ctrl stuff
465      (merged from ecco-branch)
466      - new active_file_loc... and mdsio_..._loc routines
467      - affected packages: autodiff, ctrl, grdchk, mdsio
468    
469    checkpoint51c_post
470    o introducing integer flag debugLevel
471      - debLevZero: suppress all output
472      - debLevA: standard
473      - debLevB: equivalent to current debugMode=.TRUE.
474    o introducing pathname variable mdsioLocalDir for mdsio
475      that can be specified at runtime
476      (relevant for cluster I/O to local disk)
477    `
478    >>>checkpoint51b_post
479    adjoint of ptracers
480    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM

484    o new ptracers.flow
485    o made ptracers_forcing same as external_forcing_s
486    o added verification for adjoint with ptracers
487      - adm. grdchk fail so far
488      - tlm. grdchk OK
489      - checked tapelev/comlev recomputations: OK
490    <<<checkpoint51b_pre
491    
492    checkpoint51a_post
493    o added code for biogeochemistry package
494      - new pkgs: dic, gchem
495      - new subroutine in ptracers
496    o modify code for biogeo packages
497      - in model/src and pkg/ptracers
498    
499    checkpoint51
500    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
501      - autodiff, ctrl, exf, grdchk, seaice
502      kept separate packages
503      - cost, ecco, obcs
504    o updating verification/internal_wave, verification/lab_sea
505      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
506    
507    checkpoint50i_post
508    o Preparing next differentiable checkpoint and sync
509      of MAIN vs. ecco-branch
510      - 1st step: this one is differentiable
511      - 2nd step: next(! not this) checkpoint will have updated packages
512                  from ecco-branch)
513    
514    checkpoint50h_post
515    o new package "land": provide surface BC for AIM.
516    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
517    o AIM: use true log-P extrapolation for near surface temp (= as in
518        F.Molteni paper) ; update aim.5l_cs output.
519    o New variable in PARM03 for more flexible pickups
520    o somewhat cleaned package initialisation sequence for
521      ctrl/ cost/ ecco/ in packages_... routines
522    
523    checkpoint50g_post
524    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
525      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
526      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
527        made the default because of faster convergence than ADI
528    
529    checkpoint50f_post
530    o exf totally restructured
531      - replaced all exf_set_ routines by one generic exf_set_gen.F
532        and made sure it's still differentiable
533      - split exf_getffields.F into new exf_bulkformulae.F
534      - exf_inscal_/exf_outscal_ suffixes consistent with field names

545     o removed lots of single quotes from comments
546    
547    checkpoint50e_post
548    o make KPP work with PTRACERS
549     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
550       nearly a copy of kpp_transport_s
551     - there is no analogue to SurfaceTendencyS, so I have to use
552       gPtr(of the surface layer) instead
553    o add a new platform SunFire+mpi (SunFire 15000) to genmake
554    checkpoint50e_pre
555    
556    checkpoint50d_post
557    o change kpp output from multiple-record state files to single-record state
558      files analogous to write_state.F
559    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
560      analogous to the cg2d-related output.
561    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
562      so that writing to internal file fn (with length 512) fails.
563    checkpoint50d_pre
564    
565    checkpoint50c_post
566    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
567    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
568    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
569    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
570    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
571    
572    checkpoint50c_pre
573    Merging from release1_p13:
574    o bug fix for pkg/seaice dynamic solver
575    o Added SEAICE_initialHEFF to pkg/seaice
576    
577    checkpoint50b_post
578    o store u*,v* in gU,V instead of in guNm1,gvNm1
579    o in order to put the momForcing out of the Adams-Bashforth:
580      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
581      to timestep.F
582    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
583    o re-generate output for highly sensitive test-exp:
584       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
585    
586    checkpoint50b_pre
587    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
588    o corrected CPP option mismatch in exf_Bulk... functions for case
589      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
590    
591    checkpoint50a_post
592    o Bug fix for merging between c50 and KPP.
593      ikey was passed from thermodynamics to kpp_calc via
594      common block rather than being recomputed in kpp_calc,
595      in contradiction with new key itdkey.
596      New key ikppkey created, and tamc.h headers updated.
597    
598    checkpoint50
599    - 2nd step of merge with ecco-branch:
600      merge changes in ecco-branch back into main trunk
601    - bug fix in find_alpha
602    - more storing in gmredi_calc_tensor.F, kpp_routines.F
603    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
604    - merged some sliced AD support routines
605    
606    checkpoint49
607    merged from ecco-branch:
608    o exf:
609      - Enable initialisation of forcing fields to constant
610        (runtime) values.
611      - in exf_getffields.F
612        Reduce i-/j-loop to interior domain, discarding overlaps.
613        That also fixes wrong TAF-key computations for key_1, key_2
614        with bulf formulae.
615      - exf_init.F modify #ifdef for exf_init_evap
616      - exf_getffieldrec.F, ctrl_getrec.F
617        The following INT-usages are not safe:
618          fldsecs  = int(fldsecs/fldperiod)*fldperiod
619          fldcount = int(fldsecs/fldperiod) + 1
620        and were modified.
621    o autodiff: checkpoint_lev...
622      - updated storing for bulk formulae (some arrays were missing)
623      - added state for seaice package
624      - synchronized with main branch
625    o DIVA:
626      Modif.s in
627      - the_main_loop.F
628      - the_model_main.F
629      and added cost_final_restore.F cost_final_store.F
630      o With these changes, it is possible to fully separate
631        the first forward run to compute the cost function (mdthe_main_loop)
632        and adjoint runs over individual DIVA intervals (adthe_main_loop)
633        into separate model executions.
634        This enables better tuning of DIVA to given queue sizes.
635      o Loss of cost function value in consecutive DIVA runs is
636        fixed by storing to 'costfinal' file.
637      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
638        beginning/end of adjoint integration is accounted for.
639      The current changes apply to TAF-1.4.26.
640      TAF has one remaining bug, requiring one manual change
641      (see MITgcm manual).
642    o cal: synchronized between MAIN and ecco-branch
643    
644    checkpoint48i_post
645    o Changes to restore differentiability of code w.r.t. previous tag
646      (mostly adding new routines to make list and replacing
647      pressure by totPhiHyd).
648    o Updated and merged grdchk package
649      - has both ADM and TLM checks
650      - works for single- and multi-proc.
651      - output cleaned
652      - worked successfully for parallel DIVA
653    o genmake:
654      - Adding -platform=SP4
655      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
656    o Modif. for DIVA:
657      ctrl_unpack should not be called in intermediate DIVA interval.
658      (similar thing would apply for active files such as
659      tbar, sbar, psbar, which should not be reinitialised;
660      only relevant for ecco-branch)
661    
662    checkpoint48h_post
663    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
664    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
665    o Added SEAICE_initialHEFF to pkg/seaice
666    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
667    
668    checkpoint48g_post
669    --- EOS:
670    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
671      store total Potential in totPhyHyd for diagnostics & EOS.
672    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
673    --- Pressure/geopotential gradient:
674    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
675    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
676      ( changes results of global_ocean_pressure )
677    o NLFS + z-coord.: add eta*Rho' contribution.
678    o accurate phiHyd when using interface-W at the middle between 2 centers
679     ( changes results of ideal_2D_oce )
680    o includes r* 2nd term in potential gradient.
681    
682    checkpoint48f_post
683    Merging from release1_p12:
684    o Modifications for using pkg/exf with pkg/seaice
685      - improved description of the various forcing configurations
686      - added basic radiation bulk formulae to pkg/exf
687      - units/sign fix for evap computation in exf_getffields.F
688      - updated verification/global_with_exf/results/output.txt
689    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
690      (SBO) core products, including oceanic mass, center-of-mass,
691      angular, and bottom pressure (see pkg/sbo/README.sbo).
692    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
693      to avoid negative values in shallow regions.
694      - updated verification/natl_box/results/output.txt
695      - updated verification/lab_sea/results/output.txt
696    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
697    o Added useSingleCpuIO option (see PARAMS.h).
698    o Updated useSingleCpuIO option in mdsio_writefield.F to
699      work with multi-field files, e.g., for single-file pickup.
700    o pkg/seaice:
701      - bug fix in growth.F: QNET for no shortwave case
702      - added HeffFile for specifying initial sea-ice thickness
703      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
704    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
705      kpp_transport_t.F, forward_step.F, and the_main_loop.F
706    o pkg/seaice:
707      - adjoint-friendly modifications
708      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
709    
710    checkpoint48e_post
711    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
712    o dynamics: change definition of computational domain & adapt mom_fluxform
713      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
714    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
715        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
716        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
717        global_ocean.90x40x15 global_with_exf global_ocean_pressure
718        inverted_barometer solid-body.cs-32x32x1
719      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
720    
721    checkpoint48d_post
722    o in preparation for r*:
723     a) use pre-computed gradient of hydrostatic potential:
724        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
725     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
726        => affects results of glob_oce_pressure (different truncation error)  
727      update output.txt of ideal_2D_oce & global_ocean_pressure
728    
729    checkpoint48d_pre
730    o in preparation for r*:
731      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
732      pass the 2 comp. of the grad. as arguments to momentum S/R.
733      but for the moment, only used if it does not change the results.
734    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
735    
736    checkpoint48c_post
737    Modifications in treatment of initial flux forcing controls
738    to avoid extra storing of flux fields.
739    
740    checkpoint48c_pre
741    o Added tidal_basin_2d experiment (currently 1D!)
742    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
743    
744    checkpoint48b_post
745    o r* coordinate added in #ifdef NONLIN_FRSURF block.
746     (modification to pressure gradient not yet implemented)
747    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
748      (for U & V) that are used for vertical advection of momentum.
749    
750    checkpoint48a_post
751    o In preparation for r*, use temp. array to compute vertical transport
752       in flux-form momentum pkg. => change results of few test-exp.
753      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
754                        lab_sea, natl_box & plume_on_slope
755    
756    checkpoint48
757    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
758    
759    checkpoint47j_post
760    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
761    o moved adexch from forward_step to addummy_in_stepping
762    o added exch in ctrl_map_...
763    o aveFreq.=0. at end of cost_final to avoid overwrite in
764      reverse checkpointing loop
765    o Yet more changes in gmredi:
766      * adgmredi_calc_tensor
767        avoiding all recomputation of gmredi_slope_limit
768      * adgmredi_x/y/rtransport
769        added flag for excessive storing to avoid recomp. of
770        u/v/rtans, dTdx/y/z
771        -> this is not really necessary and very memory-consuming
772      * adgmredi_slope_psi:
773        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
774      * gmredi_slope_limit
775        re-activated full calculation of taperfct for case 'ac02'
776    o updating verification/ adjoints of carbon, global_ocean.90x40x15
777    
778    checkpoint47i_post
779    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
780    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
781      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
782    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
783    o gmredi: fix few bugs.
784    
785    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
786    This will be a good checkpoint to plug into the ecco-branch.
787    o few modif.'s to get latest version adjointed
788      (mainly kick out code in ini_linear_phisurf)
789    o modif's to run adjoint with exactConserv
790    o case GM_BOLUS_ADVEC should be cleaned
791      S/R gmredi_slope_psi should be cleaned
792    o verification/carbon now has exactConserv=.TRUE.
793    
794    checkpoint47g_post
795    o time-average AIM output: becomes independent from statvars time-average
796      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
797    o After TAF bug fix:
798      Tested adjoint of gmredi package.
799      Tests were done with checkpoint47 rather than with latest
800      checkpoint47f_post since the latter is broken for the adjoint
801      verification/carbon/ contains both ADM and TLM gradient checks.
802    Here they are, before they get changed/lost/stolen.
803    Mostly modif.'s to fix numerical sensitivities.
804    Gradient checks OK for
805    - GM_taper_scheme:
806      * clipping
807      * ac02
808      * linear
809      * glw91
810      * dm95
811      * ldd97
812    - GMREDI_OPTIONS:
813      * GM_VISBECK_VARIABLE_K
814      * GM_NON_UNITY_DIAGONAL
815      * GM_EXTRA_DIAGONAL
816      * GM_BOLUS_ADVEC
817    in conjunction with data.gmredi parameters to be checked in
818    in a few minutes under verification/carbon/code/
819    
820    checkpoint47f_post
821    Merging from release1_p10:
822    o modifications for using pkg/exf with pkg/seaice
823      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
824        and SEAICE_EXTERNAL_FLUXES
825      - pkg/exf CPP options EXF_READ_EVAP and
826        EXF_NO_BULK_COMPUTATIONS
827      - usage examples are Experiments 8 and 9 in
828        verification/lab_sea/README
829      - verification/lab_sea default experiment now uses
830        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
831    
832    checkpoint47e_post
833    o created a tag prior to creating a branch
834    
835    checkpoint47d_post
836    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
837      at the bottom boundary had an erroneous half slip boundary condition
838    o added bottom drag and no slip boundary condition capabilities to
839      oceanic pressure coordinates code
840    o added new verification experiment global_ocean_pressure, this experiment is
841      also described in the tutorial section of the manual
842    checkpoint47d_pre
843    
844    checkpoint47c_post
845    o Added a verification experiment for a global cubed-sphere ocean run
846      -  verification/global_ocean.cubed32x32x30
847      -  uses pkg/therm_seaice and pkg/bulk_forcing
848    
849    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
850    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
851      when using P-coordinate; only implemented for atmospheric config.
852    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
853      NOTES: requires option NONLIN_FRSURF to be "#define".
854    o update advect_xz/results/output.txt (left from checkpoint44g_post)
855    
856    checkpoint47b_post
857    Merging from release1_p9:
858    o pkg/seaice
859      - removed GOTO's and added taf directives
860      - double precision constants to reduce the g77 (Linux)
861        to F77 (SGI) differences reported in release1_p8
862    o tools/genmake
863      - added SGI options
864    o verification/testscript
865      - updated to that of checkpoint47a_post
866    o verification/global_ocean.90x40x15/input/eedata
867      - modified for SGI f77 compatibility
868    o verification/lab_sea
869      - added description of sea-ice model
870      - added missing matlab routines
871      - added test of thermodynamics parallelization
872    
873    checkpoint47a_post
874    o new pkg: aim_v23
875     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
876       for now, keep the same surface forcing as before.
877     - Part-Cell implemented into AIM; check that Heat & Water are conserved
878     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
879     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
880    o add diagnostic of surface correction term in monitor output
881    
882    o bulk_force and therm_seaice
883    - Two packages:  bulk_force (Bulk forcing)
884      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
885    - Earlier integration from Stephaine Dutkiewicz
886      and Patrick Heimbach.
887    - Two ifdef statements for compile time,
888       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
889    
890    checkpoint47
891    differentiable version of checkpoint46n_post
892    o bug fix in quasihydrostaticterms
893    o * "clean" adjoint code (in terms of extensive recomputations)
894        can now be obtained for all GMREDI options (i.e. for
895        - GM_VISBECK_VARIABLE_K
896        - GM_NON_UNITY_DIAGONAL
897        - GM_EXTRA_DIAGONAL
898        - GM_BOLUS_ADVEC )
899      * However, wrong gradient check problem remains unsolved.
900      * New CPP options have been introduced for different
901        tapering schemes
902    o external_fields_load now part of differentiation list
903    o pressure needs multiple storing;
904      would be nice to have store_pressure at beginning or
905      end of forward_step, e.g. by having phiHyd global (5-dim.)
906      (NB: pressure is needed for certain cases in find_rho,
907      which is also invoked through convective_adjustment).
908    o recomputations in find_rho for cases
909     'JMD95'/'UNESCO' or 'MDJWF' are OK.
910    o #define ATMOSPHERIC_LOADING should be differentiable
911    o ini_forcing shifted to begining of initialise_varia
912    o Incorporating QNVS line search routines into MITgcm
913      (this is separate code, and therefore not under pkg)
914      lsopt/, optim/
915    o Updated verification/carbon/
916      - #define GM_VISBECK_VARIABLE_K
917      - GM_taper_scheme    = 'ldd97'    
918    
919    checkpoint46n_post
920    Merging from release1_p8:
921    o verification/natl_box:
922      updating new external_fields_load routine
923    o New package: pkg/seaice
924      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
925      The sea-ice code is based on Hibler (1979-1980).
926      Two sea-ice dynamic solvers, ADI and LSR, are included.
927      In addition to computing prognostic sea-ice variables and diagnosing
928      the forcing/external data fields that drive the ocean model,
929      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
930      The implied surface heat flux is then stored in variable
931      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
932      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
933      non-local transport term.  Because this call precedes model
934      thermodynamics, temperature under sea-ice may not be "exactly" at
935      the freezing point by the time theta is dumped or time-averaged.
936      N.B.: fairly large differences in accuracy occur across
937            different platforms/compilers; comparison between
938            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
939            generated output gives:
940       T           S           U           V
941      C D M    c        m  s        m  s        m  s        m  s
942      n p a R  g  m  m  e  .  m  m  e  .  m  m  e  .  m  m  e  .
943      f n k u  2  i  a  a  d  i  a  a  d  i  a  a  d  i  a  a  d
944      g d e n  d  n  x  n  .  n  x  n  .  n  x  n  .  n  x  n  .
945    
946      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
947    o GAD:
948      - generated new common blocks to account for call of
949        same gad routines with differing traceridentities
950        (needed to modify tracerIdentity indices in GAD.h)
951      - generated separate common blocks for case useCubedSphereExchange
952        (Department of Futurology)
953      - parameter lists to gmredi_?transport: added tracerIdentity
954      - added new key indices to tamc.h
955    o external_fields_load:
956      - added this routine to TAF list
957      - needed to make some common blocks global and additional storing
958        along the same lines as exf package (checkpoint_lev?_directives.h)
959    o exf:
960      updated external forcing package
961      - bug fixes carried over from ecco-branch
962        (missing OBCS_OPTIONS.h in two routines)
963      - enable easy to use "no forcing".
964      - added exf I/O for atmospheric loading
965      - added exf I/O for runoff data
966      - transfered scaling between exf <-> MITgcm to exf namelist
967    o Adding new verification experiment global_with_exf.
968      This verification experiment is almost identical to the
969      global_ocean.90x40x15 experiment, except that it uses
970      the exf (and cal) package instead of the
971      external_fields_load routine (cf README file).
972    
973    checkpoint46m_post
974    o modified testscript to return -- when there are no lines of "%MON" output
975    o added new flag "quasiHydrostatic" for QH mode
976      and new routine quasihydrostaticterms()
977    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
978      New routine: mom_u_coriolis_nh()
979    o fixed sign of non-hydrostatic metric terms in u and v equations.
980      Depend on correct sign of gravitySign.
981    o added work.pc* to .cvsignore in aim directories using ifc
982    o introduced flag for controllin non-hydrostatic metric terms
983    o removed gravitySign from PARM04
984    o switched to g77/ifc from pgf77 in aim experiments
985    
986    checkpoint46l_post
987    o made convective adjustment work with pressure coordinates:
988     - changed the direction of k-loop in convective_adjustment.F for the
989       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
990     - adjusted the reference pressure k-index in convective_adjustment.F
991     - adjusted the convection condition in convect.F (in analogy to
992       calc_ivdc.F)
993     - convective_adjustment no longer computes anything on the halos
994     - removed the warnings about negative salinity from find_rho.F and
995       find_alpha.F; instead the new routine look_for_neg_salinity, called
996       at the beginning of find_rho, find_alpha, and find_beta, does a
997       check of the entire slice, if CPP-option
998       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
999    checkpoint46l_pre
1000    
1001    checkpoint46k_post
1002    o fixed the verification/global_ocean.90x40x15 experiment:
1003     - new bathymetry (the world according to A., JMC, and M.)
1004     - new initial fields and forcing fields (*.bin files)
1005     - new POLY3.COEFFS (for the next release one should switch to a full
1006       equation of state: JMD95P or MDJWF)
1007     - fixed several errors and redundancies in the data file
1008     - experiment uses looped cells
1009     - added matlab directory with diagnostic scripts for plotting of output
1010    
1011    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
1012     - read AIM physics parameters from a file (data.aimphys)
1013     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
1014    
1015    checkpoint46j_post
1016    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
1017    o move wVel computation at the end of the time step, in S/R integr_continuity
1018    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
1019    o update timeave pkg for wVel diagnostic.
1020    checkpoint46j_pre
1021    
1022    checkpoint46i_post
1023    o Clean up AIM package (and keep the results unchanged):
1024      include CPP_OPTION and use IMPLICT NONE in all routines ;
1025      declare all the variables _RL ; use _d 0 for all numerical constants.
1026      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
1027    
1028    checkpoint46h_post
1029    o cleaned up the use of rhoNil and rhoConst.
1030      - rhoNil should only appear in the LINEAR equation of state, everywhere
1031        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
1032        and the dynamical equations are all divided by rhoConst
1033    o introduced new parameter rhoConstFresh, a reference density of fresh
1034      water, to remove the fresh water flux's dependence on rhoNil. The default
1035      value is 999.8 kg/m^3
1036    o cleanup up external_forcing.F and external_forcing_surf.F
1037      - can now be used by both OCEANIC and OCEANICP
1038    checkpoint46h_pre
1039    
1040     Added code to convert surface volume flux (fresh water) into
1041     a mass flux when using P coordinates in the ocean (OCEANICP).
1042     Note: It assumes you have set rho0=rhoConst=density of fresh water.
1043    
1044    checkpoint46g_post
1045    o Include a new diagnostic variable phiHydLow for the ocean model
1046      - in z-coordinates, it is the bottom pressure anomaly
1047      - in p-coordinates, it is the sea surface elevation
1048      - in both cases, these variable have global drift, reflecting the mass
1049        drift in z-coordinates and the volume drift in p-coordinates
1050      - included time averaging for phiHydLow, be aware of the drift!
1051    o depth-dependent computation of Bo_surf for pressure coordinates
1052      in the ocean (buoyancyRelation='OCEANICP')
1053      - requires a new routine (FIND_RHO_SCALAR) to compute density with only
1054        Theta, Salinity, and Pressure in the parameter list. This routine is
1055        presently contained in find_rho.F. This routine does not give the
1056        correct density for 'POLY3', which would be a z-dependent reference
1057        density.
1058    o cleaned up find_rho
1059      - removed obsolete 'eqn' from the parameter list.
1060    o added two new verification experiments: gop and goz
1061      (4x4 degree global ocean, 15 layers in pressure and height coordinates)
1062    checkpoint46g_pre
1063    
1064    checkpoint46f_post
1065    o Enable tangent linear (forward mode) gradient checks:
1066      - extended active file handling to g_... files
1067      - added TANGENT_SIMULATION to theSimulationMode
1068      - extended grdchk package accordingly
1069    o added tangent linear setup in verification/carbon/code_ftl
1070    o added adjoint setup in verification/front_relax/code_ad
1071    
1072    checkpoint46e_post
1073    o Added new equation of state -> MDJWF
1074      - EOS of McDougall et al., 2002, JAOT, submitted
1075      - caveat: the equation of state is only valid for a smaller (more
1076        realistic?) range of values than JMD95P/Z and UNESCO
1077      - added masks to the calculation of pressure in store_pressure
1078      - added more check values for density in check_eos (ini_eos.F), some of
1079        the old check values are out of the range of the MDJWF-eos, so don't
1080        expect perfect matches for those
1081    checkpoint46e_pre
1082    
1083    checkpoint46d_post
1084    o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and
1085      'OCEANICP', also initialised field pressure correctly in ini_eos in the
1086      case of pressure coordinates. eosType='JMD95Z' in
1087      combination with buoyancyRelation='OCEANICP' now causes an error.
1088    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1089      in find_alpha/beta.
1090    checkpoint46d_pre
1091    
1092    o Changed p = pressure(i,j,k,bi,bj)  to  p = pressure(i,j,kRef,bi,bj)
1093      so that JMD95Z and JMD95P give approptiate static stability in find_rho.
1094    
1095    checkpoint46c_post
1096    o Changes necessary for ocean in p-coordinates
1097     -  Added new buoyancy relation = 'OCEANICP'
1098     -  Added new parameters = gravitySign (this used to be contained inside
1099        the factor dRdZ which I added when we first switched to R coordinates).
1100     X GM/Redi is not compatible (yet)
1101     X bottom drag and no-slip need to be debugged.
1102    checkpoint46c_pre
1103    
1104    checkpoint46b_post
1105    o Added new equation of state -> JMD95Z and JMD95P
1106      - EOS of Jackett and McDougall, 1995, JAOT
1107      - moved all EOS parameters into EOS.h
1108      - new routines ini_eos.F, store_pressure.F
1109    o Added UNESCO EOS, but not recommended because it requires
1110      in-situ temperature (see JMD95)
1111    o Modified formatting for knudsen2.f in utils/knudsen2 and added
1112      unesco.f to be used with POLY3
1113    checkpoint46b_pre
1114    
1115    checkpoint46a_post
1116    o Added (atmospheric) pressure loading
1117      - new field in FFIELDS.h, etc...
1118      - new cpp flag ATMOSPHERIC_LOADING
1119    o Changed hFacC to _hFacC in calc_phi_hyd.F
1120    o Added SHORTWAVE_HEATING to some files for consistency
1121    checkpoint46a_pre
1122    
1123    checkpoint46
1124    further merges from release1_p5
1125    o new ctrl package
1126      - adopted from ECCO environment to enable optimization
1127      - added Eliassen Palm fluxes to controls
1128    o added Eliassen Palm flux controls to gradient check package
1129    o cost package
1130      - Compatible with new ctrl package
1131      - added Eliassen Palm cost hooks
1132      - modif's of existing cost functions
1133    o Adjoint-related bug fixes in kpp:
1134      - kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix
1135      - kpp_routines: store of Rib avoids partial recomputation bug of TAF.
1136    o autodiff package
1137      - flow directives:
1138        + new for S/R do_the_model_io
1139        + enhanced for S/R checkpoint
1140        + new gmredi.flow
1141      - Introduced CPP option ALLOW_AUTODIFF_MONITOR to
1142        disable adcommon.h/g_common.h by default.
1143      - fixed problem for adjoint of global_max
1144    o modified verification/carbon/
1145    o New setup for adjoint of global_ocean
1146    o added hooks for Eliassen Palm fluxes (dynamics.F, ini_fields.F)
1147    o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F)
1148    o incorporated hooks for sponge layer code (external_forcing.F)
1149    
1150    checkpoint45d_post
1151    o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F)
1152    o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S
1153      (affects plume_on_slope "cg2d" output)
1154    o add new parameter deltaTfreesurf for free-surface time stepping
1155    o exchange gT,gS when using staggerTimeStep & GM & Oly<4
1156    o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B
1157    o change phiMin in exp1 (to agree with documentation)
1158    o add new flags:
1159     - T,S forcing inside/outside Adams-Bashforth
1160     - turn off temp,salt advection and/or forcing
1161     - for each tracer, define internal flag for multiDimAdvection & A-B
1162    o monitor: change definition of KE to check conservation of Energy
1163    
1164    checkpoint45c_post
1165    o Removed f90 comments ("!")
1166    o Modified initialisations to enable exf package for MITgcm
1167      (without invoking ECCO_PACKAGE).
1168    o modifications to gradient check package (Martin Losch)
1169      - enable centered differences
1170      - modified format of standard output
1171    
1172    checkpoint45b_post
1173    o cleaned exchange calls in cg2d
1174    o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step
1175    o included CPP option SINGLE_LAYER_MODE in thermodynamics
1176      to configure barotropic setup (Martin Losch)
1177    o moved some initialisations within bi,bj loop in dynamics
1178      (TAF flow dependency)
1179    o in initialise_varia, moved call packages_init_variables
1180      before convective_adjustment_init
1181      (corresponding adjustment of TAF tape initialisation).
1182    o in calc_diffusivity/calc_viscosity extended domain to full overlap.
1183    
1184    checkpoint45a_post
1185    o compute Rho over the whole domain (extend iMin,jMin indices)
1186    o specific exchange for X-slice domain (case Ny=1)
1187    o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code
1188    o solve_for_pressure : set cg2d_x to zero where OBCS are applied
1189    
1190    checkpoint44h_post = checkpoint45
1191    o Fix to restore differentiability:
1192      place at which packages_init_variables is called in
1193      initialise_varia is crucial for reverse control flow.
1194    o modifications in GMRedi to enable stable adjoint
1195      (corresponding modif's in thermodynamics, dynamics)
1196    o added missing hook for sponge layer code in external_forcing
1197    o modified test cost functions
1198    o storing in gad_advection (plus removal of write(0,*)!
1199    o missing headers TR1.h added in convective_adjustment routines
1200    o errorMessageUnit set non-equal zero in eeboot
1201      (conflict on some platforms, e.g. IBM SP3)
1202    o modified carbon verif.
1203    
1204    checkpoint44h_pre
1205    o vertical grid option: allow to put the Interface at the middle between
1206      2 cell-centers ; replace delZ in pkg/kpp by drF.
1207    o GM Advective form: Tracers are advected using the residual transport (=
1208      Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
1209    
1210    checkpoint44g_post
1211    o fix surface correction term in multiDimAdvection (affects plume_on_slope
1212      results) ; ifdef missing in thermodynamics.F
1213    
1214    checkpoint44f_pre,checkpoint44f_post
1215    o added PTRACERS package
1216      This allows an arbitrary number of passive tracers to be integrated
1217      forward simultaneously with the dynamicaly model.
1218      + Implemented so far:
1219        - basic forward algorithm (time-stepping, advection, diffusion, convection)
1220        - I/O and checkpointing
1221        - GM/Redi  *but*  using the GM/Redi coefficient of Salt
1222      + Not implemented so far:
1223        - KPP
1224        - OBCS
1225      + No specific example supplied (yet) but global_ocean.90x40x15 has the
1226        necessary data.ptracer file. Simply use -enable=ptracers and uncomment
1227        line in data.pkg.
1228      + This package is disabled by default since it increases storage.
1229    
1230    
1231    o testscript: added -cleanup option
1232    o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter

1253    o real fresh water flux implemented with non-linear free-surface.
1254    
1255    chkpt44c_pre,post
1256    o few fix (mask in shap_s2, EmPmR in external_field_load,

1289    checkpoint42
1290      Fixed AD-related problems:
1291    o Store directives up-to-date with re-arranged Adams-Bashforth
1292      (mainly thermodynamics.F)

1323      
1324    checkpoint40pre8
1325    o new package rw/
1326      Added method for dumping intermediate local arrays:
1327      mdsio_writetile - same as mdsio_writefield except works from inside
1328                        bi,bj loop
1329      mdsio_writelocal - same as mdsio_writetile except works for local
1330                         arrays
1331      write_local_r? - higher-level wrapper for mdsio_writelocal
1332      Controlled by diagFreq. Defaults to zero (ie. no dumps)
1333      Example given at end of mom_vecinv.F that dumps some local arrays.
1334    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
1335      control flux-form versus vector invariant code.
1336      Switch is runtime flag vectorInvariantMomentum (defaults to false)
1337      or genmake -DISABLE ...
1338    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
1339      (additional storing is now needed for case vecinv;
1340      currently nothing implemented to switch this storing off
1341      in case fluxform is used since no CPP flag available).
1342    
1343    checkpoint40pre7
1344    o bug fix in dynamics.F
1345      calc_viscosity called before k=1,Nr loop.

1356    o bug fix in gmredi_slope_limit for ldd97
1357    
1358    checkpoint40pre5
1359    o proper initialization of Adams-Bashforth time stepping
1360      + uses forward step for very first step of model (iter=0)
1361    o re-generated *all* output since almost all output is modified by this
1362      change (sorry but we've been putting this one off for about 2 years)
1363      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
1364        *not* regenerated since they are already out of date and I don't
1365        want to create the impression that they are suddenly working.
1366    o removed KAP stuff for DEC's
1367    o modified/added many .cvsignore files in */code and */input
1368    o added new expt "solid-body.cs-32x32x1"
1369      + this uses an alternative form of ini_curvilinear_grid.F which
1370        is not necessarily any better than the current one...
1371    
1372    checkpoint40pre4
1373    o added re-initialisations of utrans,vtrans,rtrans in
1374      calc_common_factors which are crucial for TAF.

1384    
1385    checkpoint40pre2
1386    o Updated to latest branch of AJA, JMC
1387    o Added gradient check package

1395       in addummy_in_stepping
1396     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
1397     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
1398     o Included following packages:
1399       cal: calendar
1400       exf: external forcing
1401       ecco: essential routines to control use of cal, exf
1402             (NB: this is not the full ECCO environment)
1403     o disabled some packages by default in genmake
1404    
1405    checkpoint38
1406     o see notes_c37_adj.txt
1407     o corrected wrong layer index in external_forcing_t
1408     o replaced the_main_loop/forward_step by the_main_loop
1409     o removed forceoutput from write_state
1410       (replaced criteria for initial/final state)
1411     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
1412    
1413    checkpoint37
1414     o mdsio.F routine split and packaged in pkg/mdsio
1415       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
1416        used unless genmake -disable=mdsio)
1417     o allow a more precise surface-geopotential gradient for the atmosphere
1418       taking into account the change in space of Alpha (=1/rho) at the surface.
1419     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
1420       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
1421     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
1422       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
1423       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
1424     o Time-Average diagnostics defined as a pseudo package "timeave".
1425     o pickup files : old pickup (before c35) did not work with new code (c35
1426       and after) unless activating 2 commented lines in initialise-varia.
1427     o Non-Hydrostatic pickup file Pb fixed.
1428     o bug with Rigid-lid version (since c35) fixed.  
1429
