4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice/seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes
8      a serious convergence problem when open boundaries are involved
9    o pkg/ggl90: fix computation of control volumes for the case of
10      ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes
11      up half a grid cell from C-centered to W-centered (pointed out by C. Eden)
12    o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC
13    o pkg/autodiff
14      - Add inAdMode switch for SEAICEuseDYNAMICS:
15        SEAICEuseDYNAMICSinAdMode
16        (extend logic in ADAUTODIFF_INADMODE_SET)
17    o pkg/seaice
18      - Step 1 of merging ice-thickness distribution (ITD) code from
19        MITgcm_contrib/torge/itd/ (author: Torge Martin)
20        The code implements concept laid out in Thorndike et al. (1975);
21        code is enabled via CPP flag SEAICE_ITD
22        nITD (in SEAICE_SIZE.h) defines number of ice thickness categories;
23        code is not complete yet!!
24      - SEAICE_SIZE.h now included in almost all seaice routines
25    o verification (using seaice):
26      - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp.
27        global_ocean.cs32x15.seaice ; update results.
28      - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ;
29      - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp
30        offline_exf_seaice (previously compiling B-grid).
31    o pkg/exf:
32      - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow
33        to specify neither just 1 comp of wind or wind-stress, nor no surface momentum
34        forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind.
35  o pkg/layers (adjust changes from Sept 19):  o pkg/layers (adjust changes from Sept 19):
36    - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)    - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F)

51      - update AD output of lab_sea.evp (very sensitive anyway).
