4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: fix bug in evp solver, while doing that
8      - change (improve?) discretization of stress computations for both
9        cgrid-lsr and evp solver
10      - add a new routine to compute strain rates
11      - the above changes lab_sea results
12      - add no slip conditions for evp solver (off by default), lsr-version
13        may follow
14      - fix exchange for shear at Z-points (does not change lab_sea)
15      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
16        (to force the user to pick a time step since there is not "safe" way
17        of choosing it)
18    o pkg/kpp: add code to have mixing in shelf ice caverns
19    
20    checkpoint59
21    o pkg/exf:
22      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
23        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
24      - move exf header files from lower_case.h to UPPER_CASE.h ;
25        add missing cvs Header & Name
26      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
27      - add namelist param. selectStressGridPosition, exf_monFreq
28      - retire many _CLIM routines, and remove data.exf_clim
29        + params moved to data.exf
30        + climsst, climsss now handled by exf_set_gen, i.e.
31          climss?period=0 refers to constant field,
32          climss?period=-12 to monthly forcing
33      - split up namelists in data.exf
34    o pkg/seaice:
35      - remove seaice_exch and seaice_exch_uv
36      - remove superfluous exchange of theta
37      - add myThid to seaice_budget_ocean/ice
38      - add new interface for atmospheric wind forcing (C-grid only)
39        + new routine
40        + two new field (taux, tauy for stress over ice)
41        + removed one global field (DAIRN) for C-grid case only
42    o pkg/thsise
43      - 2nd set of modifs for thsice adjoint in conjunction with exf
44    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
45    
46    checkpoint58y_post
47    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
48      vertical diffusivity, similar to that in MOM4; turned on using
49      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
50      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
51    o Added capability for 3D specification of background vertical diffusion
52      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
53      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
54      "data" file that contains the 3D vertical diffusivity coefficients.
55    o ice dynamics (pkg/seaice) with thsice thermodynamics:
56      - add code within pkg thsice to advect & diffuse sea-ice fields
57      similar to (and will replace) what has been added in  seaice_advdiff.F,
58      but: - conserving Mass, Heat & Salt.
59           - better when using non-linear advection scheme (not yet fully tested)
60           - can also be used in atmospheric set-up (for now, only the diffusion).
61    
62    checkpoint58x_post
63    o IO option for global-file compact format:
64      - add options when generating topology (utils/exch2/matlab-topology-generator)
65      - add I/O capability (pkg/mdsio).
66      - adapt utils/matlab/rdmds.m to read this format.
67      for now long-line format not yet supported by pkg/mdsio (& exch2).
68    o shelfice: add a few diagnostics
69    
70    checkpoint58w_post
71    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
72      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
73      (and replace horiVertRatio in NH code).
74      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
75                         and tutorial_plume_on_slope (sensitive to truncation)
76    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
77      directly to drive seaice model (C-grid only)
78    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
79     - reintroduce computation of wind from stress,
80     - compute tau (in exf_bulkformulae.F) from windstress averaged to
81       mass points to avoid tau = 0
82     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
83    o rdmnc.m: make it work with "global" files created with gluemnc
84    o rdmnc.m : some improvements in dealing with singleton dimension
85      (tested on all testreport mnc output files).
86    o genmake2: disable pkg/profiles if netcdf test fails.
87    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
88    o move call to cal_readparms up to make calendar parameters/variable available
89      to all packages
90    
91    checkpoint58v_post
92    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
93      useDynP_inEos_Zc tested.
94    o pkg/exf: changes to properly interpolate/mask/scale initial fields
95  o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields  o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
96    and portions thereof.  See read_cs.txt for description and examples.    and portions thereof.  See read_cs.txt for description and examples.
97  o utils/matlab/cs_grid/bk_line: to compute transport through passages,  o utils/matlab/cs_grid/bk_line: to compute transport through passages,
