4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: change a discretization detail to make the B-grid code
8      "more symmetric". This change is likely to remove all "ridges/leads" that
9      where quasi-aligned with the grid in B-grid solutions. It may also be
10      the solution to the stress coupling issues with the B-grid.
11    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
12      remove .cvsignore from input dir. (since testreport no longer run here).
13    o pkg/thsice:
14     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
15     - fix reshaping of sea-ice just after advection:
16       melt all the ice only if ice-volume is too small.
17     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
18       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
19     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
20    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
21      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
22    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
23      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
24      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
25      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
26      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
27      -> update output.txt
28    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
29     this affects truncation error: -> update output.txt of exp:
30      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
31      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
32    
33    checkpoint59f
34    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
35    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
36      a bounded range (in forward mode)
37    o pkg/ecco, ctrl, autodiff and mom_common:
38     internal parameter controls, completements of implementations
39    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
40    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
41      (not seem any difference in testing results).
42    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
43       at face corners.
44    o pkg/generic_advdiff:
45     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
46      loop range indices for computing vertical advection tendency
47      and do the calculation in the interior only (no overlap) ;
48      for now, only implemented for SOM advection (to save CPU time).
49     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
50    o exch2 adjoint
51      First set of changes:
52      - add exch2 hand-written adjoint templates
53      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
54        This will require cleanup in pkg/autodiff/*.F
55        (changed routines currently kept separate in verif. code/)
56      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
57        that used to hide exch2 or cubed-sphere specific code
58        (commented via 'cph-exch2')
59    o pkg/seaice
60      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
61    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
62       output of global_ocean.cs32x15.thsice .
63    
64    checkpoint59e
65    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
66      for B-grid vector (not yet tested) and C-grid vector (<- only used
67      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
68    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
69      (#ifdef ALLOW_SALT_PLUME)
70    o gather_2d/scatter_2d: removed halo regions
71    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
72      scheme and the corresponding test case (under front_relax dir). For now,
73      only available with Skew-flux form and not yet tested in realistic set-up.
74      adjoint: store directives updated, but gradient checks deteriorated,
75      so maybe GM/Redi adjoint is now broken.
76    o seaice adjoint
77      * add AREA, HEFF, HSNOW as control variable
78        (should not change lab_sea results)
79      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
80    o pkg/seaice:
81      * added computation of saltFlux in seaice_growth;
82        For time being, sea ice salinity is assumed constant
83        contribution of snow flooding to freshening of sea ice is neglected.
84        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
85        defaults to 0.0 in order to maintain backward compatibility.
86        Typical values for SEAICE_salinity are 4 to 10 g/kg.
87      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
88      * added SEAICE_availHeatFrac, which specifies fraction of surface level
89        heat content used to melt or grow ice
90      * commented out cap of HICE: it helps keep ice thinner
91      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
92      * applied OBCS T/S mask to HEFFM sea ice mask
93    
94    checkpoint59d
95    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
96     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
97     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
98    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
99     and change default value of parameter "GM_Small_Number";
100     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
101       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
102       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
