3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
7    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
8    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
9      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
10    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
11    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
12    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
13    
14    checkpoint52d_post
15    o re-tiled many expts to allow comparison in multi-processor mode
16      - updated output accordingly
17      - changed hs94.128x64x5 to use intial T from file rather than use the
18        random number generator
19    o add infrastructure in model routines for fizhi and gridalt packages
20    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
21    o changes to permit hi-res, cubed-sphere, configuration
22      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
23      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
24      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
25        of surface winds for the cube
26      (A verification experiment, based on global_ocean.cs32x15, but with
27       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
28       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
29       complete with example surface forcing files and matlab scripts to look
30       at the output and compare it with that of global_ocean.cs32x15.)
31    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
32       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
33       to conform to the common rule.
34    o check-in the first version of the coupler + interfaces for multi-components
35       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
36       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
37       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
38       - ocean and atmos. share the same horizontal grid (no interpolation).
39       - exchanges between component and coupler is done in forward_step
40    o new verification experiment, cpl_aim+ocn:
41       coupled ocean - AIM atmosphere on cs32 grid.
42    
43    checkpoint52d_pre
44    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
45    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
46    
47    checkpoint52c_post
48    o Fixing OPTIONS files for use of exf:
49      - ALLOW_ECCO not needed
50      - ECCO_CPPOPTIONS.h should not be included from
51        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
52        as has been the case in the past
53      - All cal/exf related options are currently set in
54        single header file. Should remain so until we
55        agree on a consistent new policy.
56    o Removed all CPP options for cal package.
57      cal has no more CPP options.
58    o modified STOREs in GAD_ADVECTION
59    o corrected key comp. for passkey
60    
61    checkpoint52b_post
62    o new version: "thsice" of thermodynamic sea-ice pkg:
63     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
64     - modify fluxes but do not change theta directly;
65     - light cleaning of bulk_force pkg (still needed with thsice).
66     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
67       + output_thsice.txt to test thsice & bulk_force pkgs.
68    o put back grid & coriolis monitor output.
69    checkpoint52b_pre
70    
71    o call "do_the_model_io" at the beginning (=> dump initial state)
72    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
73    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
74      (need info on NUMBER_OF_PTRACERS)
75    o missing PTRACERS headers in some routines
76    o default tamc.h in pkg/autodiff supposed to crash
77      to ensure proper customization
78    
79    checkpoint52a_post
80    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
81      - moved surfaceTendencyTice from pkg/seaice to main code
82      - subroutine FREEZE_SURFACE now limits only surface temperature
83        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
84        => new output.txt for global_ocean.cs32x15 & global_with_exf
85      - keep the old version of FREEZE for backward compatibility;
86        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
87      - corresponding modifs for TAF directives
88    o added surface flux output variables to TIMEAVE_STATVARS
89    o time-averaged output for pkg/ptracers
90    o fix problem with ECCO-related divided adjoint
91      snapshot file was missing some ad-variables,
92      but no warning issued by TAF
93    
94    checkpoint52a_pre
95    o some bug fixes for #undef REAL4_IS_SLOW
96    
97    checkpoint52 = ecco_c52_e35
98    o after testing adjoints of checkpoint51u_post
99    
100    checkpoint51u_post
101    o this is the post-merge tag of the ecco-branch
102      (needs another clean checkout and re-testing)
103    o various natl_box_adjoint configs and results
104      but no input fields
105    o obcs adjoint not yet merged!
106    o adding ECCO global 1x1 and 2x2 degree configs
107    o updated/extended some store directives for seaice
108    o pkg/ecco now containes ecco-specific part of cost function
109    o top level routines the_main_loop, forward_step
110      supersede those in model/src/
111      previous input data.cost now in data.ecco
112      (new namelist ecco_cost_nml)
113    o in ctrl/ cleaned some cross-dependencies and updated CPP options
114    
115    checkpoint51t_post
116    o this is the pre-merge tag of the ecco-branch
117    
118    checkpoint51s_post
119    o cleanup: removed various obsolete #define-s
120    o pkg/grdchk
121      - renamed 'ph-grd 3' to 'grad-res'
122      - merged from ecco-branch
123        (remaining bug fixes for obcs gradient checks)
124      - additional high-precision output for testreport
125        (grep for 'precision_grdchk_result')
126    
127    checkpoint51r_post
128    o cleaned up or removed CPP_OPTIONS.h files
129    o updated results for some of the tests to reflect the new
130      optfiles (-ieee: -O0 instead of -O3)
131    
132    checkpoint51q_post
133    o cd_code:
134      - moved cd_scheme.F -> cd_code_scheme.F
135      - separate read_checkpoint from cd_code_ini_vars.F
136      - separated cd_code part from write_checkpoint
137      - updated AD_SOURCE, generated .flow
138      - added CD_CODE_VARS.h to the_main_loop
139      - Moving cd_code specific store dir.s to pkg/cd_code
140    o ctrl package totally restructured
141      - pack/unpack now optional and decoupled from
142        xx_/adxx_ I/O
143      - ctrl_pack/unpack cleaned
144        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
145      - confined inclusion of AD_CONFIG.h to where necessary.
146    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
147    
148    checkpoint51p_post
149  o create initial cd_code package  o create initial cd_code package
150      - WARNING: the initialization of fields within packages
151        is broken because INI_FIELDS (where READ_CHECKPOINT is
152        called) is called *before* PACKAGES_INIT_VARIABLES.
153        This seems to be backwards since
154        1) its important to initially zero the entire field including
155           the "halo" region
156        2) zeroing needs to be done *before* reading pickup info
157           and the pickup call might or might not happen in any
158           particular run
159      - this needs an overhaul for R2
160  o cleanup verification/*/code/GMREDI_OPTIONS.h  o cleanup verification/*/code/GMREDI_OPTIONS.h
161  o cleanup testreport  o cleanup testreport
162
