4      ==============================      ==============================
5    
6    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
7      atmospheric model (AIM) to use it ; add a "slab ocean" component.
8    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
9    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
10    o extending useSingleCpuIO option to work with new exch2 I/O format
11      - old-style, missing-tile I/O is still accessible by defining CPP
12        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
13    o monitor package can write to NetCDF files and/or STDOUT
14    o fix re-definition bug in MNC_GRID_INIT_ALL()
15    o doc/api_reference added
16      - a framework for building an API Reference Manual using all
17        the "protex" comments embedded in the code
18      - see pkg/generic_advdiff, pkg/mnc for examples
19    o MNC:
20      - make myThid the last argument for all subroutines
21      - new default for the grid files: NO halos
22      - add useMNC and other run-time flags
23      - separate per-file-group handling of the unlimited dimension
24      - early initialization of MNC w/ flags read at the eeboot stage
25        and lookup tables set in initialize_fixed
26      - write all MNC output to a freshly-created directory
27    o thermodynamics sea-ice (thsice) is now tested with testreport.
28    o test exp. advect_cs: use the standard cs32 grid ; update output.
29    o Added functionality to grdchk:
30      pick global i,j,k position (or nearest wet) where to perform check.
31    
32    checkpoint52l_post
33    o new land formulation:
34      a) use ground enthalpy as prognostic variable to ensure exact
35         energy conservation.
36      b) account for water temperature and for latent heat of freezing
37         in all processes (rain, run-off, ground storage)
38      c) compute surface and ground temperature implicitly.
39    o aim_v23 modification for new land model:
40      a) Treat separately land / ocean / sea-ice surface fluxes
41         to allow implicit computation of land & sea-ice surface temp.
42      b) add snow precipitation.
43    checkpoint52l_pre
44    
45    o fix problem (when 1 tile is empty) in min/max monitor.
46    o fix bug in timeAve (u,vZetatave in common block)
47    o no restoring terms under ice for pkg/seaice
48    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
49    o bug fix for pkg/seaice pickups
50    o change MNC call locations and add coordinate attributes
51    o mask vorticity at the corner ; affects global_ocean.cs output
52    o fix ini_curvilinear_grid ; test CS experiments with mpi
53    o aim.5l_cs: modify sea-ice fraction input file ; update output
54    o exf: Adding simple range check routine for exf fields after read
55    
56    checkpoint52k_post
57    o removed top-level directory "diags"
58      - we migrated these functions to pkg/timeave a long time ago
59    o fixed bug introduced in pkg/monitor
60    o accuracy ctrlprec = 32 insuffient for gradient checks using
61      averaged fields (I/O via cost_averages)
62      -> use ctrl.h in active_file*.F to control I/O precision.
63    o paramter list of CALL ADTHE_MAIN_LOOP
64    o added initial do_the_model_io to ecco
65    o set all ...Freq to zero after cost_final
66      taveFreq, dumpFreq, pChkptFreq
67    o MAIN and ECCO differentiability restored
68    
69    checkpoint52j_post
70    o fix nchklev in tamc.h for global_ocean...
71    o Bringing flow and store directives up-to-date
72    o Really weird thing!
73      call do_the_model_io from the_main_loop with parameters
74      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
75      TAF places a faulty re-call of initialise_varia
76      after cost_final call which should not be there!
77    checkpoint52j_pre
78    
79    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
80      error messages
81    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
82    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
83      debug output
84    o modfied mdsio_writefield.F to handle non-global files under exch2
85    o update AIM Cubed-Sphere exp (aim.5l_cs):
86      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
87    o update AIM Equatorial Channel exp:
88      use standard aim_v23 pkg and change the SST fields to be more realistic.
89    o globalFile now works with exch2
90    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
91      mon_vort3.F to make exch2 friendly with >1 tile per cube face
92    o limit timeave output for hi-res integrations
93    
94    checkpoint52i_post
95    o removed CPP_EEOPTIONS.h from verification/*/code
96    o updated the tiling for global_ocean_pressure
97    checkpoint52i_pre
98    
99    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
100      the old pkg/aim).
101    
102    checkpoint52h_pre
103    o shortened offending lines in exch2_send_rx?.template
104    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
105    o genmake2: add build & execute test for NetCDF code
106    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
107      old grid files, moved CPP_EEMACROS.h to pkg/exch2
108    o added useSingleCPUIO flag to monitor.F and mon_out.F
109    o added temporary hack for sea-ice dynamics on the cube:
110      metric terms are ignored and it is assumed that
111      there is no sea-ice on cube faces 1, 2, 4, and 5.
112    
113    checkpoint52f_post
114    o added exch2 cube routines to pkg/exch2
115    o modified hs94.cs-32x32x5 to use it
116    o added new grid files to hs94.cs-32x32x5
117    checkpoint52f_pre
118    
119    checkpoint52e_post
120    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
121      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
122    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
123      to work with implicit vertical advection and AB ;
124    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
125    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
126     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
127    checkpoint52e_pre
128    
129    o fix bug in impldiff when Nr=1 or Nr=2.
130    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
131    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
132    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
133      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
134    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
135    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
136    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
137    
138    checkpoint52d_post
139    o re-tiled many expts to allow comparison in multi-processor mode
140      - updated output accordingly
141      - changed hs94.128x64x5 to use intial T from file rather than use the
142        random number generator
143    o add infrastructure in model routines for fizhi and gridalt packages
144    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
145    o changes to permit hi-res, cubed-sphere, configuration
146      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
147      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
148      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
149        of surface winds for the cube
150      (A verification experiment, based on global_ocean.cs32x15, but with
151       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
152       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
153       complete with example surface forcing files and matlab scripts to look
154       at the output and compare it with that of global_ocean.cs32x15.)
155    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
156       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
157       to conform to the common rule.
158    o check-in the first version of the coupler + interfaces for multi-components
159       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
160       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
161       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
162       - ocean and atmos. share the same horizontal grid (no interpolation).
163       - exchanges between component and coupler is done in forward_step
164    o new verification experiment, cpl_aim+ocn:
165       coupled ocean - AIM atmosphere on cs32 grid.
166    
167    checkpoint52d_pre
168    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
169    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
170    
171    checkpoint52c_post
172    o Fixing OPTIONS files for use of exf:
173      - ALLOW_ECCO not needed
174      - ECCO_CPPOPTIONS.h should not be included from
175        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
176        as has been the case in the past
177      - All cal/exf related options are currently set in
178        single header file. Should remain so until we
179        agree on a consistent new policy.
180    o Removed all CPP options for cal package.
181      cal has no more CPP options.
182    o modified STOREs in GAD_ADVECTION
183    o corrected key comp. for passkey
184    
185    checkpoint52b_post
186    o new version: "thsice" of thermodynamic sea-ice pkg:
187     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
188     - modify fluxes but do not change theta directly;
189     - light cleaning of bulk_force pkg (still needed with thsice).
190     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
191       + output_thsice.txt to test thsice & bulk_force pkgs.
192    o put back grid & coriolis monitor output.
193    checkpoint52b_pre
194    
195    o call "do_the_model_io" at the beginning (=> dump initial state)
196    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
197    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
198      (need info on NUMBER_OF_PTRACERS)
199    o missing PTRACERS headers in some routines
200    o default tamc.h in pkg/autodiff supposed to crash
201      to ensure proper customization
202    
203    checkpoint52a_post
204    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
205      - moved surfaceTendencyTice from pkg/seaice to main code
206      - subroutine FREEZE_SURFACE now limits only surface temperature
207        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
208        => new output.txt for global_ocean.cs32x15 & global_with_exf
209      - keep the old version of FREEZE for backward compatibility;
210        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
211      - corresponding modifs for TAF directives
212    o added surface flux output variables to TIMEAVE_STATVARS
213    o time-averaged output for pkg/ptracers
214    o fix problem with ECCO-related divided adjoint

216      but no warning issued by TAF
217    
218    checkpoint52a_pre
219    o some bug fixes for #undef REAL4_IS_SLOW
220    
221    checkpoint52 = ecco_c52_e35
222    o after testing adjoints of checkpoint51u_post
223    
224    checkpoint51u_post
225    o this is the post-merge tag of the ecco-branch
226      (needs another clean checkout and re-testing)
227    o various natl_box_adjoint configs and results
228      but no input fields
229    o obcs adjoint not yet merged!
230    o adding ECCO global 1x1 and 2x2 degree configs
231    o updated/extended some store directives for seaice
232    o pkg/ecco now containes ecco-specific part of cost function
233    o top level routines the_main_loop, forward_step
234      supersede those in model/src/
235      previous input data.cost now in data.ecco
236      (new namelist ecco_cost_nml)
237    o in ctrl/ cleaned some cross-dependencies and updated CPP options
238    
239    checkpoint51t_post
240    o this is the pre-merge tag of the ecco-branch
241    
242    checkpoint51s_post
243    o cleanup: removed various obsolete #define-s
244    o pkg/grdchk
245      - renamed 'ph-grd 3' to 'grad-res'
246      - merged from ecco-branch
247        (remaining bug fixes for obcs gradient checks)
248      - additional high-precision output for testreport
249        (grep for 'precision_grdchk_result')
250    
251    checkpoint51r_post
252    o cleaned up or removed CPP_OPTIONS.h files
253    o updated results for some of the tests to reflect the new
254      optfiles (-ieee: -O0 instead of -O3)
255    
256    checkpoint51q_post
257    o cd_code:
258      - moved cd_scheme.F -> cd_code_scheme.F
259      - separate read_checkpoint from cd_code_ini_vars.F
260      - separated cd_code part from write_checkpoint
261      - updated AD_SOURCE, generated .flow
262      - added CD_CODE_VARS.h to the_main_loop
263      - Moving cd_code specific store dir.s to pkg/cd_code
264    o ctrl package totally restructured
265      - pack/unpack now optional and decoupled from
266        xx_/adxx_ I/O
267      - ctrl_pack/unpack cleaned
268        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
269      - confined inclusion of AD_CONFIG.h to where necessary.
270    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
271    
272    checkpoint51p_post
273    o create initial cd_code package
274      - WARNING: the initialization of fields within packages
275        is broken because INI_FIELDS (where READ_CHECKPOINT is
276        called) is called *before* PACKAGES_INIT_VARIABLES.
277        This seems to be backwards since
278        1) its important to initially zero the entire field including
279           the "halo" region
280        2) zeroing needs to be done *before* reading pickup info
281           and the pickup call might or might not happen in any
282           particular run
283      - this needs an overhaul for R2
284    o cleanup verification/*/code/GMREDI_OPTIONS.h
285    o cleanup testreport
286    
287    checkpoint51o_post
288    o bringing AD-related verif's up to date with genmake2

290      - global_ocean.90x40x15/
291      - hs.94.1x64x5/
292      - (front_relax/ )
293    o (more) consistent directory structure for AD-related verif.'s
294    o cleaning ALLOW_GRADIENT_CHECK -> ALLOW_GRDCHK
295    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
296    o bug fix in find_alpha.F for MDJWF:
297      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
298        change rho -> rho-rhoConst
299      - replace call find_rho to find_rhonum
300    o initialisation of rFlx extended to full array (required by TAF)
301      and shifted to thermodynamics
302    o removed PTRACERS.h in ptracers routine
303    o added surfacetendencyPtr to S/R parameter list pracers_forcing

311    o added the [#include "AD_CONFIG.h"] statement to all files that need
312       it for adjoint/tl #defines
313     o re-worked the build logic in genmake2 to support AD_CONFIG.h
314     o removed tools/genmake since it no longer works
315

317    o modifications to make FREEZE flux visible to pkg/kpp
318      - moved surfaceTendencyTice from pkg/seaice to main code
319      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
320      - subroutine FREEZE now limits only surface temperature
321        (this means new output.txt for global_ocean.90x40x15,
322         global_ocean.cs32x15, and global_with_exf)
323    o added surface flux output variables to TIMEAVE_STATVARS
324    
325    checkpoint51n_pre
326    o added "#undef ALLOW_USE_MPI" support to eesupp/src/gather_2d.F
327    o added [#include "AD_CONFIG.h"] to all files that use the following
328      defines:

346    checkpoint51l_pre
347    o add salt flux to forcing fields (used when salty sea-ice forms or melts)
348    o enable to apply restoring on S & T only in a latitude band.
349    o update output (external_forcing_surf modif. change truncation errors)
350       global_ocean.cs32x15, global_ocean_pressure, lab_sea, natl_box
351    
352    checkpoint51k_post
353    o change default to: useNHMTerms=.FALSE.
354     - new output.txt for atmos. exp (NHMTerms were wrong but now turned off):
355       adjustment.128x64x1, aim.5l_Eq_Ch, aim.5l_LatLon, hs94.128x64x5, hs94.1x64x5

414      - This is a temporary Cartesian-grid hack until
415        the super-duper ESMF coupler becomes available.
416      - See verification/global_with_exf/README for usage example.
417      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
418        flags and modified pkg/seaice accordingly.
419    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
420        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
421        non-local transport term.
422    
423    checkpoint51e_post
424    o pkg/mom_vecinv:
425      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)
426      - add time-ave diagnostic of vorticity advection.
427    o add diagnostic (instantaneous) of Shapiro Filter effect for T,S & UV.
428    o atmospheric geopotential: - include water vapor effect;
429                                - use p^kappa in p* scaling.
430    o land pkg: read initial state from files.
431    o AIM : add stratospheric drag in the upper level
432    
433    checkpoint51d_post
434    o change function ILNBLNK (=> last non-blank char.) to return zero
435      (instead of the string length) when the string. char is empty
436    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
437    o modif's to restore TAMC compatibility
438      - avoid "_d" constructs in PARAMETER declarations
439      - avoid interrupting lines by comment lines
440    o Use cluster local disks for purely local I/O
441      vs. globally visible disks needed for ctrl stuff
442      (merged from ecco-branch)
443      - new active_file_loc... and mdsio_..._loc routines
444      - affected packages: autodiff, ctrl, grdchk, mdsio
445    
446    checkpoint51c_post
447    o introducing integer flag debugLevel
448      - debLevZero: suppress all output
449      - debLevA: standard
450      - debLevB: equivalent to current debugMode=.TRUE.
451    o introducing pathname variable mdsioLocalDir for mdsio
452      that can be specified at runtime
453      (relevant for cluster I/O to local disk)
454    `
455    >>>checkpoint51b_post
456    adjoint of ptracers
457    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
458    o extended state in checkpoint_lev?, etc.
459    o alternative ctrl/cost with tr1 or ptracer
460    o new comlev1_bibj_ptracers
461    o new ptracers.flow
462    o made ptracers_forcing same as external_forcing_s
463    o added verification for adjoint with ptracers
464      - adm. grdchk fail so far
465      - tlm. grdchk OK
466      - checked tapelev/comlev recomputations: OK
467    <<<checkpoint51b_pre
468    
469    checkpoint51a_post
470    o added code for biogeochemistry package
471      - new pkgs: dic, gchem
472      - new subroutine in ptracers
473    o modify code for biogeo packages
474      - in model/src and pkg/ptracers
475    
476  checkpoint51  checkpoint51
477  o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN  o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
478    - autodiff, ctrl, exf, grdchk, seaice    - autodiff, ctrl, exf, grdchk, seaice
479    kept separate packages    kept separate packages
480    - cost, ecco, obcs    - cost, ecco, obcs
481    o updating verification/internal_wave, verification/lab_sea
482      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
483    
484  checkpoint50i_post  checkpoint50i_post
