4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/kpp: add code to have mixing in shelf ice caverns
8    
9    checkpoint59
10    o pkg/exf:
11      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
12        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
13      - move exf header files from lower_case.h to UPPER_CASE.h ;
14        add missing cvs Header & Name
15      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
16      - add namelist param. selectStressGridPosition, exf_monFreq
17      - retire many _CLIM routines, and remove data.exf_clim
18        + params moved to data.exf
19        + climsst, climsss now handled by exf_set_gen, i.e.
20          climss?period=0 refers to constant field,
21          climss?period=-12 to monthly forcing
22      - split up namelists in data.exf
23    o pkg/seaice:
24      - remove seaice_exch and seaice_exch_uv
25      - remove superfluous exchange of theta
26      - add myThid to seaice_budget_ocean/ice
27      - add new interface for atmospheric wind forcing (C-grid only)
28        + new routine
29        + two new field (taux, tauy for stress over ice)
30        + removed one global field (DAIRN) for C-grid case only
31    o pkg/thsise
32      - 2nd set of modifs for thsice adjoint in conjunction with exf
33    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
34    
35    checkpoint58y_post
36    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
37      vertical diffusivity, similar to that in MOM4; turned on using
38      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
39      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
40    o Added capability for 3D specification of background vertical diffusion
41      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
42      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
43      "data" file that contains the 3D vertical diffusivity coefficients.
44    o ice dynamics (pkg/seaice) with thsice thermodynamics:
45      - add code within pkg thsice to advect & diffuse sea-ice fields
46      similar to (and will replace) what has been added in  seaice_advdiff.F,
47      but: - conserving Mass, Heat & Salt.
48           - better when using non-linear advection scheme (not yet fully tested)
49           - can also be used in atmospheric set-up (for now, only the diffusion).
50    
51    checkpoint58x_post
52    o IO option for global-file compact format:
53      - add options when generating topology (utils/exch2/matlab-topology-generator)
54      - add I/O capability (pkg/mdsio).
55      - adapt utils/matlab/rdmds.m to read this format.
56      for now long-line format not yet supported by pkg/mdsio (& exch2).
57    o shelfice: add a few diagnostics
58    
59    checkpoint58w_post
60    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
61      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
62      (and replace horiVertRatio in NH code).
63      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
64                         and tutorial_plume_on_slope (sensitive to truncation)
65    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
66      directly to drive seaice model (C-grid only)
67    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
68     - reintroduce computation of wind from stress,
69     - compute tau (in exf_bulkformulae.F) from windstress averaged to
70       mass points to avoid tau = 0
71     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
72    o rdmnc.m: make it work with "global" files created with gluemnc
73    o rdmnc.m : some improvements in dealing with singleton dimension
74      (tested on all testreport mnc output files).
75    o genmake2: disable pkg/profiles if netcdf test fails.
76    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
77    o move call to cal_readparms up to make calendar parameters/variable available
78      to all packages
79    
80    checkpoint58v_post
81    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
82      useDynP_inEos_Zc tested.
83    o pkg/exf: changes to properly interpolate/mask/scale initial fields
84    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
85      and portions thereof.  See read_cs.txt for description and examples.
86    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
87      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
88      following the great-circle arc between those 2 points.
89    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
90      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
91    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
92     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
93     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
94     - still needs work (not working with some options ; efficiency to improve)
95       and serious testing.
96     - use this scheme for temperature & salinity in 2 advection test exp.:
97       advect_xy & advect_xz, respectively.
98    
99    checkpoint58u_post
100    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
101    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
102    o testreport: add option "-skipdir" to skip some test.
103    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
104      momentum calculation.
105    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
106    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
107      remove checkpoint.F and the_correction_step.F (no longer used);
108      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
109    o add option (linFSConserveTr) to correct for tracer source/sink due to
110      Linear Free surface
111    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
112    o pkg/thsice: fix reading mnc-pickups
113    
114    checkpoint58t_post
115    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
116    o pkg/mdsio:
117     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
118       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
119       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
120     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
121     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
122       either MDS_READ_FIELD or MDS_WRITE_FIELD )
123     - new S/R (to replace MDSWRITEMETA), which allows to write more
124       informations (variable names, time ...) to meta files.
125     - modify rdmds.m to give back the meta file content.
126    o pkg/diagnostics: change vertical interpolation to be safer, and more
127       flexible (define p-levels to interpolate to in data.diagnostics);
128      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
129       diagnostic pointer.
130    o pkg/seaice: more cleaning up of seaice_growth, added many comments
131    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
132  o fix multi-category seaice:  o fix multi-category seaice:
133   - change cpp flag SEAICE_MULTILEVEL to more meaningful name:   - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
134     SEAICE_MULTICATEGORY     SEAICE_MULTICATEGORY
135   - fix short wave heat flux   - fix short wave heat flux
136    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
137       and allow to use EVP solver. Change forward lab_sea: test both EVP
138       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
139  o Initial check-in of lab_sea adjoint  o Initial check-in of lab_sea adjoint
140    (very similar to natl_box_adjoint/code_seaice)    (very similar to natl_box_adjoint/code_seaice)
141    * used C-grid and EVP solver    * used C-grid and EVP solver
