4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/obcs: change default to OBCSfixTopo = .true.,
8      set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
9    o implementation of TAF directives for gchem,cfc,dic
10    o remove "exp5" (replaced by tutorial_deep_convection).
11    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
12      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
13      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
14      --> changes results in exp4, seaice_obcs
15    o tutorial_deep_convection :
16      update the set-up and increase resolution and domain size ; start
17      from pseudo initial conditions = output at t=120mn in order to see
18      something happening when running testreport.
19    o pkg/seaice: add os7mp as an advection scheme
20                  add check for advection schemes
21                  add a flag for restoring T and S underneath sea ice
22    o pkg/my82: add netcdf-support and diagnostics
23    o thsice pkg:
24      - Now hsMax limits snow height by turning it into ice following
25        flooding scheme (and now conserving energy)
26      - Slight rewriting of the formula in thsice_calc_thick.F
27      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
28      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
29    
30    checkpoint59p
31    o gchem / dic / cfc :
32      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
33      - add new parameter files: "data.dic" & "data.cfc" ;
34      - various re-arrangement in initialisation & header file ;
35      - fix tutorial_global_oce_biogeo for multi-threaded test.
36    o pkg/dic: test for "pickup_dic" file when restarting ;
37      if no pickup-file, can restart with a re-initialised pH (same as it did
38      before) providing pickupStrictlyMatch is set to False.
39    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
40      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
41    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
42      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
43    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
44     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
45       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
46    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
47       scheme to use for vorticty-term ;
48     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
49       (with default selectVortScheme, return to original discretisation)
50     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
51    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
52    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
53      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
54      also fix diagnostics VISCAHW & VISCA4W.
55    
56    checkpoint59o
57    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
58    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
59      move a few statemens out the main loop into separate loops
60    o pkg/shelfice:
61      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
62        (kg/m^2/s), does not break tests, because in verification/isomip,
63        rhoConstFresh=rhoConst (by accident)
64      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
65      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
66        new file model/src/seawater.F, so that they are available for all pkgs.
67      - convert potential temperature into in-situ temperature. This changes the
68        isomip tests => update tests
69    o add a flag writePickupAtEnd (default=true) to be able to suppress
70      writing a pickup at the last timestep
71    o tools/mpack-1.6 :
72      - disable automake (not working) and autoconf (not needed).
73      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
74        also cleaner with much less compilation warnings.
75    o pkg/profiles:
76      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
77      (for "less than 32 characters name" compiler requirement)
78    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
79      conditions that have a different sampling frequency than S/T/U/V obcs
80    o pkg/diagnostics (stats-diags):
81      - fix global Min/Max in case 1 processor get only empty tiles
82    o genmake2: replace (4 times)
83         make genmake_tc_1.o >> genmake_warnings 2>&1
84      with
85         COMM="$CC $CFLAGS -c genmake_tc_1.c"
86         echo $COMM >> genmake_warnings
87         $COMM >> genmake_warnings 2>&1
88      to make genmake2 always see the value of CC as specified in the optfile.
89  o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.  o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
90    - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.    - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
91    - modify verification advect_cs test to test SOM-advection on CS-grid.    - modify verification advect_cs test to test SOM-advection on CS-grid.
