4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/kpp
8     - remove wrong (within bi,bj loops) EXCH calls.
9     - little cleaning (add argument myThid in last position, cvs header ...)
10     - move computation of surface related input fields to KPP into a new
11       subroutine kpp_forcing_surf.F
12    o pkg/seaice
13     - check for inconsistent evp parameter/cpp-flag combination
14     - remove leftover errIO flat for obsolete name list error handling
15    
16    checkpoint59a
17    o pkg/seaice: some parameter clarifications and a little bit of clean up
18    o pkg/thsice: rename run-time parameters:
19       himin       -> hIceMin
20       himin0      -> hThinIce
21       hihig       -> hThickIce
22       i0          -> i0swFrac
23       transCoef   -> bMeltCoef
24       frac_energy -> fracMelting
25      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
26       with default values (for now) that do not change the results.
27      remove old version of thsice vars advection in pkg/seaice.
28    o in FFIELDS.h:
29      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
30      - make pLoad & sIceLoad always available (but still only used if
31         ATMOSPHERIC_LOADING is #define).
32    o pkg/kpp: replaced _KPP_RL with _RL
33    o bug fixes for vertical diffusivity computations when both KPP and
34        3D diffusivity arrays are used.
35    o pkg/seaice: fix bug in evp solver, while doing that
36      - change (improve?) discretization of stress computations for both
37        cgrid-lsr and evp solver
38      - add a new routine to compute strain rates
39      - the above changes lab_sea results
40      - add no slip conditions for evp solver (off by default), lsr-version
41        may follow
42      - fix exchange for shear at Z-points (does not change lab_sea)
43      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
44        (to force the user to pick a time step since there is not "safe" way
45        of choosing it)
46      - add principal stress diagnostics
47      - rearrange fields for evp a little to avoid having to call a: too many
48        exchanges and b: exchanges for stress trensor components which we do
49        not have.
50      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
51        of evp, complete rewrite for lsr case (latter is does not yet work
52        in all cases)
53    o pkg/kpp: add code to have mixing in shelf ice caverns
54      - add myThid to all kpp routines (long overdue)
55    
56    checkpoint59
57    o pkg/exf:
58      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
59        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
60      - move exf header files from lower_case.h to UPPER_CASE.h ;
61        add missing cvs Header & Name
62      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
63      - add namelist param. selectStressGridPosition, exf_monFreq
64      - retire many _CLIM routines, and remove data.exf_clim
65        + params moved to data.exf
66        + climsst, climsss now handled by exf_set_gen, i.e.
67          climss?period=0 refers to constant field,
68          climss?period=-12 to monthly forcing
69      - split up namelists in data.exf
70    o pkg/seaice:
71      - remove seaice_exch and seaice_exch_uv
72      - remove superfluous exchange of theta
73      - add myThid to seaice_budget_ocean/ice
74      - add new interface for atmospheric wind forcing (C-grid only)
75        + new routine
76        + two new field (taux, tauy for stress over ice)
77        + removed one global field (DAIRN) for C-grid case only
78    o pkg/thsise
79      - 2nd set of modifs for thsice adjoint in conjunction with exf
80    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
81    
82    checkpoint58y_post
83    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
84      vertical diffusivity, similar to that in MOM4; turned on using
85      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
86      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
87    o Added capability for 3D specification of background vertical diffusion
88      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
89      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
90      "data" file that contains the 3D vertical diffusivity coefficients.
91    o ice dynamics (pkg/seaice) with thsice thermodynamics:
92      - add code within pkg thsice to advect & diffuse sea-ice fields
93      similar to (and will replace) what has been added in  seaice_advdiff.F,
94      but: - conserving Mass, Heat & Salt.
95           - better when using non-linear advection scheme (not yet fully tested)
96           - can also be used in atmospheric set-up (for now, only the diffusion).
97    
98  checkpoint58x_post  checkpoint58x_post
99  o IO option for global-file compact format:  o IO option for global-file compact format:
100    - add options when generating topology (utils/exch2/matlab-topology-generator)    - add options when generating topology (utils/exch2/matlab-topology-generator)
