4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
8      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
9    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
10     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
11       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
12    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
13       scheme to use for vorticty-term ;
14     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
15       (with default selectVortScheme, return to original discretisation)
16     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
17    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
18    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
19      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
20      also fix diagnostics VISCAHW & VISCA4W.
21    
22    checkpoint59o
23    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
24    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
25      move a few statemens out the main loop into separate loops
26    o pkg/shelfice:
27      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
28        (kg/m^2/s), does not break tests, because in verification/isomip,
29        rhoConstFresh=rhoConst (by accident)
30      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
31      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
32        new file model/src/seawater.F, so that they are available for all pkgs.
33      - convert potential temperature into in-situ temperature. This changes the
34        isomip tests => update tests
35    o add a flag writePickupAtEnd (default=true) to be able to suppress
36      writing a pickup at the last timestep
37    o tools/mpack-1.6 :
38      - disable automake (not working) and autoconf (not needed).
39      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
40        also cleaner with much less compilation warnings.
41    o pkg/profiles:
42      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
43      (for "less than 32 characters name" compiler requirement)
44    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
45      conditions that have a different sampling frequency than S/T/U/V obcs
46    o pkg/diagnostics (stats-diags):
47      - fix global Min/Max in case 1 processor get only empty tiles
48    o genmake2: replace (4 times)
49         make genmake_tc_1.o >> genmake_warnings 2>&1
50      with
51         COMM="$CC $CFLAGS -c genmake_tc_1.c"
52         echo $COMM >> genmake_warnings
53         $COMM >> genmake_warnings 2>&1
54      to make genmake2 always see the value of CC as specified in the optfile.
55  o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.  o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
56    - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.    - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
57    - modify verification advect_cs test to test SOM-advection on CS-grid.    - modify verification advect_cs test to test SOM-advection on CS-grid.
