4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
8      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
9      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
10      --> changes results in dome, exp4, internal_wave, seaice_obcs, and
11      tutorial_plume_on_slope.
12    o tutorial_deep_convection :
13      update the set-up and increase resolution and domain size ; start
14      from pseudo initial conditions = output at t=120mn in order to see
15      something happening when running testreport.
16    o pkg/seaice: add os7mp as an advection scheme
17                  add check for advection schemes
18                  add a flag for restoring T and S underneath sea ice
19    o pkg/my82: add netcdf-support and diagnostics
20    o thsice pkg:
21      - Now hsMax limits snow height by turning it into ice following
22        flooding scheme (and now conserving energy)
23      - Slight rewriting of the formula in thsice_calc_thick.F
24      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
25        --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
26    
27    checkpoint59p
28    o gchem / dic / cfc :
29      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
30      - add new parameter files: "data.dic" & "data.cfc" ;
31      - various re-arrangement in initialisation & header file ;
32      - fix tutorial_global_oce_biogeo for multi-threaded test.
33    o pkg/dic: test for "pickup_dic" file when restarting ;
34      if no pickup-file, can restart with a re-initialised pH (same as it did
35      before) providing pickupStrictlyMatch is set to False.
36    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
37      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
38    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
39      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
40    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
41     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
42       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
43    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
44       scheme to use for vorticty-term ;
45     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
46       (with default selectVortScheme, return to original discretisation)
47     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
48    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
49    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
50      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
51      also fix diagnostics VISCAHW & VISCA4W.
52    
53    checkpoint59o
54    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
55    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
56      move a few statemens out the main loop into separate loops
57    o pkg/shelfice:
58      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
59        (kg/m^2/s), does not break tests, because in verification/isomip,
60        rhoConstFresh=rhoConst (by accident)
61      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
62      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
63        new file model/src/seawater.F, so that they are available for all pkgs.
64      - convert potential temperature into in-situ temperature. This changes the
65        isomip tests => update tests
66    o add a flag writePickupAtEnd (default=true) to be able to suppress
67      writing a pickup at the last timestep
68    o tools/mpack-1.6 :
69      - disable automake (not working) and autoconf (not needed).
70      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
71        also cleaner with much less compilation warnings.
72    o pkg/profiles:
73      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
74      (for "less than 32 characters name" compiler requirement)
75    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
76      conditions that have a different sampling frequency than S/T/U/V obcs
77    o pkg/diagnostics (stats-diags):
78      - fix global Min/Max in case 1 processor get only empty tiles
79  o genmake2: replace (4 times)  o genmake2: replace (4 times)
80       make genmake_tc_1.o >> genmake_warnings 2>&1       make genmake_tc_1.o >> genmake_warnings 2>&1
