3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o genmake2: add build & execute test for NetCDF code
7    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
8      old grid files, moved CPP_EEMACROS.h to pkg/exch2
9    o added useSingleCPUIO flag to monitor.F and mon_out.F
10    o added temporary hack for sea-ice dynamics on the cube:
11      metric terms are ignored and it is assumed that
12      there is no sea-ice on cube faces 1, 2, 4, and 5.
13    
14    checkpoint52f_post
15    o added exch2 cube routines to pkg/exch2
16    o modified hs94.cs-32x32x5 to use it
17    o added new grid files to hs94.cs-32x32x5
18    checkpoint52f_pre
19    
20    checkpoint52e_post
21    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
22      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
23    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
24      to work with implicit vertical advection and AB ;
25    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
26    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
27     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
28    checkpoint52e_pre
29    
30    o fix bug in impldiff when Nr=1 or Nr=2.
31    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
32    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
33    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
34      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
35    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
36    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
37    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
38    
39    checkpoint52d_post
40    o re-tiled many expts to allow comparison in multi-processor mode
41      - updated output accordingly
42      - changed hs94.128x64x5 to use intial T from file rather than use the
43        random number generator
44    o add infrastructure in model routines for fizhi and gridalt packages
45    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
46    o changes to permit hi-res, cubed-sphere, configuration
47      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
48      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
49      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
50        of surface winds for the cube
51      (A verification experiment, based on global_ocean.cs32x15, but with
52       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
53       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
54       complete with example surface forcing files and matlab scripts to look
55       at the output and compare it with that of global_ocean.cs32x15.)
56    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
57       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
58       to conform to the common rule.
59    o check-in the first version of the coupler + interfaces for multi-components
60       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
61       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
62       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
63       - ocean and atmos. share the same horizontal grid (no interpolation).
64       - exchanges between component and coupler is done in forward_step
65    o new verification experiment, cpl_aim+ocn:
66       coupled ocean - AIM atmosphere on cs32 grid.
67    
68    checkpoint52d_pre
69    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
70    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
71    
72    checkpoint52c_post
73    o Fixing OPTIONS files for use of exf:
74      - ALLOW_ECCO not needed
75      - ECCO_CPPOPTIONS.h should not be included from
76        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
77        as has been the case in the past
78      - All cal/exf related options are currently set in
79        single header file. Should remain so until we
80        agree on a consistent new policy.
81    o Removed all CPP options for cal package.
82      cal has no more CPP options.
83    o modified STOREs in GAD_ADVECTION
84    o corrected key comp. for passkey
85    
86    checkpoint52b_post
87    o new version: "thsice" of thermodynamic sea-ice pkg:
88     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
89     - modify fluxes but do not change theta directly;
90     - light cleaning of bulk_force pkg (still needed with thsice).
91     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
92       + output_thsice.txt to test thsice & bulk_force pkgs.
93    o put back grid & coriolis monitor output.
94    checkpoint52b_pre
95    
96    o call "do_the_model_io" at the beginning (=> dump initial state)
97    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
98    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
99      (need info on NUMBER_OF_PTRACERS)
100    o missing PTRACERS headers in some routines
101    o default tamc.h in pkg/autodiff supposed to crash
102      to ensure proper customization
103    
104    checkpoint52a_post
105    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
106      - moved surfaceTendencyTice from pkg/seaice to main code
107      - subroutine FREEZE_SURFACE now limits only surface temperature
108        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
109        => new output.txt for global_ocean.cs32x15 & global_with_exf
110      - keep the old version of FREEZE for backward compatibility;
111        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
112      - corresponding modifs for TAF directives
113    o added surface flux output variables to TIMEAVE_STATVARS
114    o time-averaged output for pkg/ptracers
115    o fix problem with ECCO-related divided adjoint
116      snapshot file was missing some ad-variables,
117      but no warning issued by TAF
118    
119    checkpoint52a_pre
120    o some bug fixes for #undef REAL4_IS_SLOW
121    
122    checkpoint52 = ecco_c52_e35
123    o after testing adjoints of checkpoint51u_post
124    
125    checkpoint51u_post
126    o this is the post-merge tag of the ecco-branch
127      (needs another clean checkout and re-testing)
128    o various natl_box_adjoint configs and results
129      but no input fields
130    o obcs adjoint not yet merged!
131    o adding ECCO global 1x1 and 2x2 degree configs
132    o updated/extended some store directives for seaice
133    o pkg/ecco now containes ecco-specific part of cost function
134    o top level routines the_main_loop, forward_step
135      supersede those in model/src/
136      previous input data.cost now in data.ecco
137      (new namelist ecco_cost_nml)
138    o in ctrl/ cleaned some cross-dependencies and updated CPP options
139    
140    checkpoint51t_post
141    o this is the pre-merge tag of the ecco-branch
142    
143    checkpoint51s_post
144    o cleanup: removed various obsolete #define-s
145    o pkg/grdchk
146      - renamed 'ph-grd 3' to 'grad-res'
147      - merged from ecco-branch
148        (remaining bug fixes for obcs gradient checks)
149      - additional high-precision output for testreport
150        (grep for 'precision_grdchk_result')
151    
152    checkpoint51r_post
153    o cleaned up or removed CPP_OPTIONS.h files
154    o updated results for some of the tests to reflect the new
155      optfiles (-ieee: -O0 instead of -O3)
156    
157  checkpoint51q_post  checkpoint51q_post
158  o cd_code:  o cd_code:
159    - moved cd_scheme.F -> cd_code_scheme.F    - moved cd_scheme.F -> cd_code_scheme.F
