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      - changes lab_sea results
12    o pkg/kpp: add code to have mixing in shelf ice caverns
13    
14    checkpoint59
15    o pkg/exf:
16      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
17        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
18      - move exf header files from lower_case.h to UPPER_CASE.h ;
19        add missing cvs Header & Name
20      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
21      - add namelist param. selectStressGridPosition, exf_monFreq
22      - retire many _CLIM routines, and remove data.exf_clim
23        + params moved to data.exf
24        + climsst, climsss now handled by exf_set_gen, i.e.
25          climss?period=0 refers to constant field,
26          climss?period=-12 to monthly forcing
27      - split up namelists in data.exf
28    o pkg/seaice:
29      - remove seaice_exch and seaice_exch_uv
30      - remove superfluous exchange of theta
31      - add myThid to seaice_budget_ocean/ice
32      - add new interface for atmospheric wind forcing (C-grid only)
33        + new routine
34        + two new field (taux, tauy for stress over ice)
35        + removed one global field (DAIRN) for C-grid case only
36    o pkg/thsise
37      - 2nd set of modifs for thsice adjoint in conjunction with exf
38    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
39    
40    checkpoint58y_post
41    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
42      vertical diffusivity, similar to that in MOM4; turned on using
43      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
44      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
45    o Added capability for 3D specification of background vertical diffusion
46      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
47      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
48      "data" file that contains the 3D vertical diffusivity coefficients.
49    o ice dynamics (pkg/seaice) with thsice thermodynamics:
50      - add code within pkg thsice to advect & diffuse sea-ice fields
51      similar to (and will replace) what has been added in  seaice_advdiff.F,
52      but: - conserving Mass, Heat & Salt.
53           - better when using non-linear advection scheme (not yet fully tested)
54           - can also be used in atmospheric set-up (for now, only the diffusion).
55    
56    checkpoint58x_post
57    o IO option for global-file compact format:
58      - add options when generating topology (utils/exch2/matlab-topology-generator)
59      - add I/O capability (pkg/mdsio).
60      - adapt utils/matlab/rdmds.m to read this format.
61      for now long-line format not yet supported by pkg/mdsio (& exch2).
62    o shelfice: add a few diagnostics
63    
64    checkpoint58w_post
65    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
66      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
67      (and replace horiVertRatio in NH code).
68      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
69                         and tutorial_plume_on_slope (sensitive to truncation)
70    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
71      directly to drive seaice model (C-grid only)
72    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
73     - reintroduce computation of wind from stress,
74     - compute tau (in exf_bulkformulae.F) from windstress averaged to
75       mass points to avoid tau = 0
76     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
77    o rdmnc.m: make it work with "global" files created with gluemnc
78    o rdmnc.m : some improvements in dealing with singleton dimension
79      (tested on all testreport mnc output files).
80    o genmake2: disable pkg/profiles if netcdf test fails.
81    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
82    o move call to cal_readparms up to make calendar parameters/variable available
83      to all packages
84    
85    checkpoint58v_post
86    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
87      useDynP_inEos_Zc tested.
88    o pkg/exf: changes to properly interpolate/mask/scale initial fields
89    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
90      and portions thereof.  See read_cs.txt for description and examples.
91    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
92      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
93      following the great-circle arc between those 2 points.
94    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
95      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
96    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
97     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
98     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
99     - still needs work (not working with some options ; efficiency to improve)
100       and serious testing.
101     - use this scheme for temperature & salinity in 2 advection test exp.:
102       advect_xy & advect_xz, respectively.
103    
104    checkpoint58u_post
105    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
106    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
107    o testreport: add option "-skipdir" to skip some test.
108    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
109      momentum calculation.
110    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
111    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
112      remove checkpoint.F and the_correction_step.F (no longer used);
113      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
114    o add option (linFSConserveTr) to correct for tracer source/sink due to
115      Linear Free surface
116    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
117    o pkg/thsice: fix reading mnc-pickups
118    
119  checkpoint58t_post  checkpoint58t_post
120  o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)  o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
