6      debug output
7    o modfied mdsio_writefield.F to handle non-global files under exch2
8    o update AIM Cubed-Sphere exp (aim.5l_cs):
9      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
10    o update AIM Equatorial Channel exp:
11      use standard aim_v23 pkg and change the SST fields to be more realistic.
12    o globalFile now works with exch2
13    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
14      mon_vort3.F to make exch2 friendly with >1 tile per cube

17    
18    checkpoint52i_post
19    o removed CPP_EEOPTIONS.h from verification/*/code
20    o updated the tiling for global_ocean_pressure
21    checkpoint52i_pre
22    
23    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
24      the old pkg/aim).
25    
26    checkpoint52h_pre
27    o shortened offending lines in exch2_send_rx?.template
28    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator

31      old grid files, moved CPP_EEMACROS.h to pkg/exch2
32    o added useSingleCPUIO flag to monitor.F and mon_out.F
33    o added temporary hack for sea-ice dynamics on the cube:
34      metric terms are ignored and it is assumed that
35      there is no sea-ice on cube faces 1, 2, 4, and 5.
36    
37    checkpoint52f_post
38    o added exch2 cube routines to pkg/exch2
39    o modified hs94.cs-32x32x5 to use it
40    o added new grid files to hs94.cs-32x32x5
41    checkpoint52f_pre
42    
43    checkpoint52e_post
44    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
45      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
46    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
47      to work with implicit vertical advection and AB ;
48    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
49    o update output (gad_calc_rhs.F changes affect truncation error) of exp:

56    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
57      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
58    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
59    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
60    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
61

63    o re-tiled many expts to allow comparison in multi-processor mode
64      - updated output accordingly
65      - changed hs94.128x64x5 to use intial T from file rather than use the
66        random number generator
67    o add infrastructure in model routines for fizhi and gridalt packages
68    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
69    o changes to permit hi-res, cubed-sphere, configuration
70      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
71      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
72      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
73        of surface winds for the cube
74      (A verification experiment, based on global_ocean.cs32x15, but with
75       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
76       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
77       complete with example surface forcing files and matlab scripts to look
78       at the output and compare it with that of global_ocean.cs32x15.)
79    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
80       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
81       to conform to the common rule.
82    o check-in the first version of the coupler + interfaces for multi-components
83       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
84       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
85       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
86       - ocean and atmos. share the same horizontal grid (no interpolation).
87       - exchanges between component and coupler is done in forward_step
88    o new verification experiment, cpl_aim+ocn:
89       coupled ocean - AIM atmosphere on cs32 grid.
90    
91    checkpoint52d_pre
92    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
93    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
94    
95    checkpoint52c_post
96    o Fixing OPTIONS files for use of exf:
97      - ALLOW_ECCO not needed
98      - ECCO_CPPOPTIONS.h should not be included from
99        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
100        as has been the case in the past
101      - All cal/exf related options are currently set in
102        single header file. Should remain so until we
103        agree on a consistent new policy.
104    o Removed all CPP options for cal package.
105      cal has no more CPP options.
106    o modified STOREs in GAD_ADVECTION
107    o corrected key comp. for passkey
108    
109    checkpoint52b_post
110    o new version: "thsice" of thermodynamic sea-ice pkg:
111     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
112     - modify fluxes but do not change theta directly;
113     - light cleaning of bulk_force pkg (still needed with thsice).
114     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
115       + output_thsice.txt to test thsice & bulk_force pkgs.
116    o put back grid & coriolis monitor output.
117    checkpoint52b_pre
118    
119    o call "do_the_model_io" at the beginning (=> dump initial state)
120    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
121    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
122      (need info on NUMBER_OF_PTRACERS)
123    o missing PTRACERS headers in some routines
124    o default tamc.h in pkg/autodiff supposed to crash
125      to ensure proper customization
126    
127    checkpoint52a_post
128    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
129      - moved surfaceTendencyTice from pkg/seaice to main code
130      - subroutine FREEZE_SURFACE now limits only surface temperature
131        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
132        => new output.txt for global_ocean.cs32x15 & global_with_exf
133      - keep the old version of FREEZE for backward compatibility;
134        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.

143    o some bug fixes for #undef REAL4_IS_SLOW
144    
145    checkpoint52 = ecco_c52_e35
146    o after testing adjoints of checkpoint51u_post
147    
148    checkpoint51u_post
149    o this is the post-merge tag of the ecco-branch
150      (needs another clean checkout and re-testing)
151    o various natl_box_adjoint configs and results
152      but no input fields
153    o obcs adjoint not yet merged!
154    o adding ECCO global 1x1 and 2x2 degree configs
155    o updated/extended some store directives for seaice
156    o pkg/ecco now containes ecco-specific part of cost function
157    o top level routines the_main_loop, forward_step
158      supersede those in model/src/
159      previous input data.cost now in data.ecco
160      (new namelist ecco_cost_nml)
161    o in ctrl/ cleaned some cross-dependencies and updated CPP options
162    
163    checkpoint51t_post
164    o this is the pre-merge tag of the ecco-branch
165    
166    checkpoint51s_post

168    o pkg/grdchk
169      - renamed 'ph-grd 3' to 'grad-res'
170      - merged from ecco-branch
171        (remaining bug fixes for obcs gradient checks)
172      - additional high-precision output for testreport
173        (grep for 'precision_grdchk_result')
174    
175    checkpoint51r_post
176    o cleaned up or removed CPP_OPTIONS.h files
177    o updated results for some of the tests to reflect the new
178      optfiles (-ieee: -O0 instead of -O3)
179    
180    checkpoint51q_post
181    o cd_code:
182      - moved cd_scheme.F -> cd_code_scheme.F
183      - separate read_checkpoint from cd_code_ini_vars.F
184      - separated cd_code part from write_checkpoint
185      - updated AD_SOURCE, generated .flow

187      - Moving cd_code specific store dir.s to pkg/cd_code
188    o ctrl package totally restructured
189      - pack/unpack now optional and decoupled from
190        xx_/adxx_ I/O

194    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
195    
196    checkpoint51p_post
197    o create initial cd_code package
198      - WARNING: the initialization of fields within packages
199        is broken because INI_FIELDS (where READ_CHECKPOINT is
200        called) is called *before* PACKAGES_INIT_VARIABLES.
201        This seems to be backwards since
202        1) its important to initially zero the entire field including
203           the "halo" region
204        2) zeroing needs to be done *before* reading pickup info
205           and the pickup call might or might not happen in any
206           particular run
207      - this needs an overhaul for R2
208    o cleanup verification/*/code/GMREDI_OPTIONS.h
209    o cleanup testreport

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

246         global_ocean.cs32x15, and global_with_exf)
247    o added surface flux output variables to TIMEAVE_STATVARS

419        F.Molteni paper) ; update aim.5l_cs output.
420    o New variable in PARM03 for more flexible pickups
421    o somewhat cleaned package initialisation sequence for
422      ctrl/ cost/ ecco/ in packages_... routines
423    
424    checkpoint50g_post
425    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
426      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
427      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
428        made the default because of faster convergence than ADI
429    
430    checkpoint50f_post
431    o exf totally restructured
432      - replaced all exf_set_ routines by one generic exf_set_gen.F
433        and made sure it's still differentiable
434      - split exf_getffields.F into new exf_bulkformulae.F
435      - exf_inscal_/exf_outscal_ suffixes consistent with field names
436      - updated adjoint/makefile and relevant verif. accordingly
437    
438    checkpoint50f_pre
439     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
440          + change Evap over land. (update aim.5l_cs output)
441     o added missing .cvsignores and made uniform across expts
442     o changed configuration of tidal_basin_2d expt
443     o added pkg/debug functions for tracing code in fatal crashes
444     o tidied pkg/monitor to use MONITOR_OPTIONS.h
445     o new fn in pkg/monitor to stop model if solution grows too big
446     o removed lots of single quotes from comments
447    
448    checkpoint50e_post
449    o make KPP work with PTRACERS
450     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
451       nearly a copy of kpp_transport_s
452     - there is no analogue to SurfaceTendencyS, so I have to use
453       gPtr(of the surface layer) instead
454    o add a new platform SunFire+mpi (SunFire 15000) to genmake
455    checkpoint50e_pre
456    
457    checkpoint50d_post
458    o change kpp output from multiple-record state files to single-record state
459      files analogous to write_state.F
460    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
461      analogous to the cg2d-related output.
462    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
463      so that writing to internal file fn (with length 512) fails.
464    checkpoint50d_pre
465    
466    checkpoint50c_post
467    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
468    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
469    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
470    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
471    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
472    
473    checkpoint50c_pre
474    Merging from release1_p13:
475    o bug fix for pkg/seaice dynamic solver
476    o Added SEAICE_initialHEFF to pkg/seaice
477    
478    checkpoint50b_post
479    o store u*,v* in gU,V instead of in guNm1,gvNm1
480    o in order to put the momForcing out of the Adams-Bashforth:
481      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
482      to timestep.F
483    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
484    o re-generate output for highly sensitive test-exp:
485       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
486    
487    checkpoint50b_pre
488    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
489    o corrected CPP option mismatch in exf_Bulk... functions for case
490      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
491    
492  checkpoint50a_post  checkpoint50a_post
493  o Bug fix for merging between c50 and KPP.  o Bug fix for merging between c50 and KPP.
