4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
8      transitions for useExfYearlyFields
9    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
10      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
11      subroutines (which could be generated from a template, because they are
12      almost identical), for now they are included in obcs_prescribe_read.F for
13      simplicity
14    o pkg/exf:
15      - add a little more diagnostic to exf_interp_read (in analogy to
16        mds_read_field, can be turned off with debugLevel < debugLevA=1)
17      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
18        ugly but fast by unrolling short inner loops, inserting a unroll=8
19        directive in routine lagran, and splitting a loop and making do while the
20        outermost loop (the latter requires the intoduction of index arrays)
21    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
22    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
23      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
24    o verification/seaice_obcs: updated for restart test and latest options
25    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
26      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
27      for now this is only available for the C-grid code and also within
28      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
29    
30    checkpoint59m
31    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
32      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
33    o gad_som : fix flux output (& diagnostics) to have same units as other  
34      advection scheme fluxes (was previously multiplied by deltaT).  
35    o added verification/seaice_obcs both to test seaice open boundaries
36      and to provide an example matlab scrpt for generating them
37    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
38    o pkg/salt_plume: clean up salt_plume_frac.F to
39      remove redundancy in PlumeMethod 1 and 4
40    o pkg/kpp: added saltplume diagnostics
41    o pkg/obcs and pkg/seaice:
42      - do not set uice and vice to zero when OB*icefile are unspecified
43      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
44      - moved seaice tracer obcs after call to seaice_growth
45    o pkg/salt_plume: added various options for salt plume depth
46      criterion and for vertical distribution of the salt
47    
48    checkpoint59l
49    o pkg/ptracers: new version of ptracers pickup:
50      read meta file and write only fields which are needed to restart.
51      ( same logic as main pickup file ; also using pickupStrictlyMatch )
52    o pkg/seaice:
53      - add timescale for melting due to warm mixed layer as a means of
54        setting SEAICE_availHeatFrac more conveniently
55      - add a CPP-flag/runtime parameter check for flooding algorithm
56      - reformulated availHeat in seaice_growth.F to be independent of AREA
57    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
58      unit changes
59  o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint  o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
60  o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC  o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
