4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
8    o pkg/exf: some cleaning-up:
9      - change various "constants" into runtime parameters
10      - cleaned-up Large&Yeager04 routine which should eventually
11        replace exf_bulkformulae.F (changed names of S/R and CPP)
12        and merged various ALLOW_ATM_WIND options
13     only used with thsice pkg (in thsice_get_exf.F):
14      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
15        which are used when useStabilityFct_overIce=TRUE (= the default)
16      - change default values of ice & snow emissivity and scale downward LW
17        by ice & snow emissivity.
18    o pkg/thsice:
19     fix few little problems, in thsice_calc_thickn.F:
20      - growth vertically (and not laterally) if iceFrac == iceMaskMax
21      - melt laterally only if hIce < hThinIce (as the comments say)
22      and in thsice_extend.F:
23      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
24      - start to form ice as soon as the minimum ice-volume is reachable.
25     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
26      and cpl_aim+ocn
27    o pkg/kpp
28     - move computation of surface related input fields to KPP into a new
29       subroutine kpp_forcing_surf.F
30     - remove wrong (within bi,bj loops) EXCH calls.
31     - little cleaning (add argument myThid in last position, cvs header ...)
32     - for now, fix conservation problem by exchanging KPPviscAz (may not
33       be the best fix)
34    o pkg/seaice
35     - check for inconsistent evp parameter/cpp-flag combination
36     - remove leftover errIO flat for obsolete name list error handling
37    
38    checkpoint59a
39    o pkg/seaice: some parameter clarifications and a little bit of clean up
40    o pkg/thsice: rename run-time parameters:
41       himin       -> hIceMin
42       himin0      -> hThinIce
43       hihig       -> hThickIce
44       i0          -> i0swFrac
45       transCoef   -> bMeltCoef
46       frac_energy -> fracMelting
47      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
48       with default values (for now) that do not change the results.
49      remove old version of thsice vars advection in pkg/seaice.
50    o in FFIELDS.h:
51      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
52      - make pLoad & sIceLoad always available (but still only used if
53         ATMOSPHERIC_LOADING is #define).
54    o pkg/kpp: replaced _KPP_RL with _RL
55    o bug fixes for vertical diffusivity computations when both KPP and
56        3D diffusivity arrays are used.
57    o pkg/seaice: fix bug in evp solver, while doing that
58      - change (improve?) discretization of stress computations for both
59        cgrid-lsr and evp solver
60      - add a new routine to compute strain rates
61      - the above changes lab_sea results
62      - add no slip conditions for evp solver (off by default), lsr-version
63        may follow
64      - fix exchange for shear at Z-points (does not change lab_sea)
65      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
66        (to force the user to pick a time step since there is not "safe" way
67        of choosing it)
68      - add principal stress diagnostics
69      - rearrange fields for evp a little to avoid having to call a: too many
70        exchanges and b: exchanges for stress trensor components which we do
71        not have.
72      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
73        of evp, complete rewrite for lsr case (latter is does not yet work
74        in all cases)
75    o pkg/kpp: add code to have mixing in shelf ice caverns
76      - add myThid to all kpp routines (long overdue)
77    
78    checkpoint59
79  o pkg/exf:  o pkg/exf:
80    - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &    - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
81      ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid      ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
82    - move exf header files from lower_case.h to UPPER_CASE.h ;    - move exf header files from lower_case.h to UPPER_CASE.h ;
83      add missing cvs Header & Name      add missing cvs Header & Name
84    - add adjoint routines and flow dirs for newly used exch_uv_agrid routines    - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
85      - add namelist param. selectStressGridPosition, exf_monFreq
86      - retire many _CLIM routines, and remove data.exf_clim
87        + params moved to data.exf
88        + climsst, climsss now handled by exf_set_gen, i.e.
89          climss?period=0 refers to constant field,
90          climss?period=-12 to monthly forcing
91      - split up namelists in data.exf
92  o pkg/seaice:  o pkg/seaice:
93    - remove seaice_exch and seaice_exch_uv    - remove seaice_exch and seaice_exch_uv
94    - remove superfluous exchange of theta    - remove superfluous exchange of theta

99      + removed one global field (DAIRN) for C-grid case only      + removed one global field (DAIRN) for C-grid case only

101    - 2nd set of modifs for thsice adjoint in conjunction with exf    - 2nd set of modifs for thsice adjoint in conjunction with exf
102    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
