4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o in FFIELDS.h:
8      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
9      - make pLoad & sIceLoad always available (but still only used if
10         ATMOSPHERIC_LOADING is #define).
11    o pkg/kpp: replaced _KPP_RL with _RL
12    o bug fixes for vertical diffusivity computations when both KPP and
13        3D diffusivity arrays are used.
14    o pkg/seaice: fix bug in evp solver, while doing that
15      - change (improve?) discretization of stress computations for both
16        cgrid-lsr and evp solver
17      - add a new routine to compute strain rates
18      - the above changes lab_sea results
19      - add no slip conditions for evp solver (off by default), lsr-version
20        may follow
21      - fix exchange for shear at Z-points (does not change lab_sea)
22      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
23        (to force the user to pick a time step since there is not "safe" way
24        of choosing it)
25      - add principal stress diagnostics
26      - rearrange fields for evp a little to avoid having to call a: too many
27        exchanges and b: exchanges for stress trensor components which we do
28        not have.
29      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
30        of evp, complete rewrite for lsr case (latter is does not yet work
31        in all cases)
32    o pkg/kpp: add code to have mixing in shelf ice caverns
33    
34    checkpoint59
35    o pkg/exf:
36      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
37        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
38      - move exf header files from lower_case.h to UPPER_CASE.h ;
39        add missing cvs Header & Name
40      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
41      - add namelist param. selectStressGridPosition, exf_monFreq
42      - retire many _CLIM routines, and remove data.exf_clim
43        + params moved to data.exf
44        + climsst, climsss now handled by exf_set_gen, i.e.
45          climss?period=0 refers to constant field,
46          climss?period=-12 to monthly forcing
47      - split up namelists in data.exf
48    o pkg/seaice:
49      - remove seaice_exch and seaice_exch_uv
50      - remove superfluous exchange of theta
51      - add myThid to seaice_budget_ocean/ice
52      - add new interface for atmospheric wind forcing (C-grid only)
53        + new routine
54        + two new field (taux, tauy for stress over ice)
55        + removed one global field (DAIRN) for C-grid case only
56    o pkg/thsise
57      - 2nd set of modifs for thsice adjoint in conjunction with exf
58    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
59    
60    checkpoint58y_post
61    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
62      vertical diffusivity, similar to that in MOM4; turned on using
63      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
64      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
65    o Added capability for 3D specification of background vertical diffusion
66      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
67      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
68      "data" file that contains the 3D vertical diffusivity coefficients.
69    o ice dynamics (pkg/seaice) with thsice thermodynamics:
70      - add code within pkg thsice to advect & diffuse sea-ice fields
71      similar to (and will replace) what has been added in  seaice_advdiff.F,
72      but: - conserving Mass, Heat & Salt.
73           - better when using non-linear advection scheme (not yet fully tested)
74           - can also be used in atmospheric set-up (for now, only the diffusion).
75    
76    checkpoint58x_post
77    o IO option for global-file compact format:
78      - add options when generating topology (utils/exch2/matlab-topology-generator)
79      - add I/O capability (pkg/mdsio).
80      - adapt utils/matlab/rdmds.m to read this format.
81      for now long-line format not yet supported by pkg/mdsio (& exch2).
82    o shelfice: add a few diagnostics
83    
84  checkpoint58w_post  checkpoint58w_post
85  o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:  o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
86    rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref    rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
