3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
7      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
8    checkpoint52e_pre
9    
10    o fix bug in impldiff when Nr=1 or Nr=2.
11    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
12    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
13    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
14      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
15    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
16    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
17    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
18    
19    checkpoint52d_post
20    o re-tiled many expts to allow comparison in multi-processor mode
21      - updated output accordingly
22      - changed hs94.128x64x5 to use intial T from file rather than use the
23        random number generator
24    o add infrastructure in model routines for fizhi and gridalt packages
25    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
26    o changes to permit hi-res, cubed-sphere, configuration
27      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
28      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
29      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
30        of surface winds for the cube
31      (A verification experiment, based on global_ocean.cs32x15, but with
32       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
33       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
34       complete with example surface forcing files and matlab scripts to look
35       at the output and compare it with that of global_ocean.cs32x15.)
36    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
37       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
38       to conform to the common rule.
39    o check-in the first version of the coupler + interfaces for multi-components
40       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
41       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
42       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
43       - ocean and atmos. share the same horizontal grid (no interpolation).
44       - exchanges between component and coupler is done in forward_step
45    o new verification experiment, cpl_aim+ocn:
46       coupled ocean - AIM atmosphere on cs32 grid.
47    
48    checkpoint52d_pre
49    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
50    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
51    
52    checkpoint52c_post
53    o Fixing OPTIONS files for use of exf:
54      - ALLOW_ECCO not needed
55      - ECCO_CPPOPTIONS.h should not be included from
56        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
57        as has been the case in the past
58      - All cal/exf related options are currently set in
59        single header file. Should remain so until we
60        agree on a consistent new policy.
61    o Removed all CPP options for cal package.
62      cal has no more CPP options.
63    o modified STOREs in GAD_ADVECTION
64    o corrected key comp. for passkey
65    
66    checkpoint52b_post
67    o new version: "thsice" of thermodynamic sea-ice pkg:
68     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
69     - modify fluxes but do not change theta directly;
70     - light cleaning of bulk_force pkg (still needed with thsice).
71     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
72       + output_thsice.txt to test thsice & bulk_force pkgs.
73    o put back grid & coriolis monitor output.
74    checkpoint52b_pre
75    
76    o call "do_the_model_io" at the beginning (=> dump initial state)
77    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
78    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
79      (need info on NUMBER_OF_PTRACERS)
80    o missing PTRACERS headers in some routines
81    o default tamc.h in pkg/autodiff supposed to crash
82      to ensure proper customization
83    
84    checkpoint52a_post
85    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
86      - moved surfaceTendencyTice from pkg/seaice to main code
87      - subroutine FREEZE_SURFACE now limits only surface temperature
88        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
89        => new output.txt for global_ocean.cs32x15 & global_with_exf
90      - keep the old version of FREEZE for backward compatibility;
91        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
92      - corresponding modifs for TAF directives
93    o added surface flux output variables to TIMEAVE_STATVARS
94    o time-averaged output for pkg/ptracers
95    o fix problem with ECCO-related divided adjoint
96      snapshot file was missing some ad-variables,
97      but no warning issued by TAF
98    
99    checkpoint52a_pre
100    o some bug fixes for #undef REAL4_IS_SLOW
101    
102    checkpoint52 = ecco_c52_e35
103    o after testing adjoints of checkpoint51u_post
104    
105    checkpoint51u_post
106    o this is the post-merge tag of the ecco-branch
107      (needs another clean checkout and re-testing)
108    o various natl_box_adjoint configs and results
109      but no input fields
110    o obcs adjoint not yet merged!
111    o adding ECCO global 1x1 and 2x2 degree configs
112    o updated/extended some store directives for seaice
113    o pkg/ecco now containes ecco-specific part of cost function
114    o top level routines the_main_loop, forward_step
115      supersede those in model/src/
116      previous input data.cost now in data.ecco
117      (new namelist ecco_cost_nml)
118    o in ctrl/ cleaned some cross-dependencies and updated CPP options
119    
120    checkpoint51t_post
121    o this is the pre-merge tag of the ecco-branch
122    
123    checkpoint51s_post
124    o cleanup: removed various obsolete #define-s
125    o pkg/grdchk
126      - renamed 'ph-grd 3' to 'grad-res'
127      - merged from ecco-branch
128        (remaining bug fixes for obcs gradient checks)
129      - additional high-precision output for testreport
130        (grep for 'precision_grdchk_result')
131    
132    checkpoint51r_post
133    o cleaned up or removed CPP_OPTIONS.h files
134    o updated results for some of the tests to reflect the new
135      optfiles (-ieee: -O0 instead of -O3)
136    
137    checkpoint51q_post
138    o cd_code:
139      - moved cd_scheme.F -> cd_code_scheme.F
140      - separate read_checkpoint from cd_code_ini_vars.F
141      - separated cd_code part from write_checkpoint
142      - updated AD_SOURCE, generated .flow
143      - added CD_CODE_VARS.h to the_main_loop
144      - Moving cd_code specific store dir.s to pkg/cd_code
145    o ctrl package totally restructured
146      - pack/unpack now optional and decoupled from
147        xx_/adxx_ I/O
148      - ctrl_pack/unpack cleaned
149        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
150      - confined inclusion of AD_CONFIG.h to where necessary.
151    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
152    
153  checkpoint51p_post  checkpoint51p_post
