4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o thsice pkg:
8      - Now hsMax limits snow heitght by turning it into ice following
9        flooding scheme (and now conserving energy)
10      - Slight rewriting of the formula in thsice_calc_thick.F
11      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
12        --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
13    
14    checkpoint59p
15    o gchem / dic / cfc :
16      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
17      - add new parameter files: "data.dic" & "data.cfc" ;
18      - various re-arrangement in initialisation & header file ;
19      - fix tutorial_global_oce_biogeo for multi-threaded test.
20    o pkg/dic: test for "pickup_dic" file when restarting ;
21      if no pickup-file, can restart with a re-initialised pH (same as it did
22      before) providing pickupStrictlyMatch is set to False.
23    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
24      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
25    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
26      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
27    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
28     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
29       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
30    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
31       scheme to use for vorticty-term ;
32     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
33       (with default selectVortScheme, return to original discretisation)
34     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
35    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
36    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
37      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
38      also fix diagnostics VISCAHW & VISCA4W.
39    
40    checkpoint59o
41    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
42    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
43      move a few statemens out the main loop into separate loops
44    o pkg/shelfice:
45      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
46        (kg/m^2/s), does not break tests, because in verification/isomip,
47        rhoConstFresh=rhoConst (by accident)
48      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
49      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
50        new file model/src/seawater.F, so that they are available for all pkgs.
51      - convert potential temperature into in-situ temperature. This changes the
52        isomip tests => update tests
53    o add a flag writePickupAtEnd (default=true) to be able to suppress
54      writing a pickup at the last timestep
55    o tools/mpack-1.6 :
56      - disable automake (not working) and autoconf (not needed).
57      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
58        also cleaner with much less compilation warnings.
59  o pkg/profiles:  o pkg/profiles:
60    rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg    rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
61    (for "less than 32 characters name" compiler requirement)    (for "less than 32 characters name" compiler requirement)
