4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/generic_advdiff:
8      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
9      applies to files where Temperature & Salinity 2nd Order moments are used.
10    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
11      this uses a dynamically allocated internal state data structure
12      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
13      and requires a fortran 90 compiler
14    
15    checkpoint59q
16    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
17       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
18    o Refresh tutorial_global_oce_biogeo, notably:
19      - change bathymetry (put back seamounts in ACC, use hFacs)
20      - change EOS (POLY3 --> JMD95Z)
21      - use Bryan-Lewis vertical diffusivity
22      - use multidimensional advection
23      - remove old virtual virtual in dic pkg, now done through ptracer pkg
24      - change a couple of parameters in dic pkg
25    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
26    o pkg/obcs: change default to OBCSfixTopo = .true.,
27      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
28      - replace "debugMode" with "debugLevel .GE. debLevB"
29    o implementation of TAF directives for gchem,cfc,dic
30    o remove "exp5" (replaced by tutorial_deep_convection).
31    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
32      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
33      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
34      --> changes results in exp4, seaice_obcs
35    o tutorial_deep_convection :
36      update the set-up and increase resolution and domain size ; start
37      from pseudo initial conditions = output at t=120mn in order to see
38      something happening when running testreport.
39    o pkg/seaice: add os7mp as an advection scheme
40                  add check for advection schemes
41                  add a flag for restoring T and S underneath sea ice
42    o pkg/my82: add netcdf-support and diagnostics
43    o thsice pkg:
44      - Now hsMax limits snow height by turning it into ice following
45        flooding scheme (and now conserving energy)
46      - Slight rewriting of the formula in thsice_calc_thick.F
47      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
48      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
49    
50    checkpoint59p
51    o gchem / dic / cfc :
52      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
53      - add new parameter files: "data.dic" & "data.cfc" ;
54      - various re-arrangement in initialisation & header file ;
55      - fix tutorial_global_oce_biogeo for multi-threaded test.
56    o pkg/dic: test for "pickup_dic" file when restarting ;
57      if no pickup-file, can restart with a re-initialised pH (same as it did
58      before) providing pickupStrictlyMatch is set to False.
59    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
60      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
61    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
62      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
63    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
64     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
65       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
66    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
67       scheme to use for vorticty-term ;
68     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
69       (with default selectVortScheme, return to original discretisation)
70     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
71    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
72    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
73      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
74      also fix diagnostics VISCAHW & VISCA4W.
75    
76    checkpoint59o
77    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
78    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
79      move a few statemens out the main loop into separate loops
80    o pkg/shelfice:
81      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
82        (kg/m^2/s), does not break tests, because in verification/isomip,
83        rhoConstFresh=rhoConst (by accident)
84      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
85      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
86        new file model/src/seawater.F, so that they are available for all pkgs.
87      - convert potential temperature into in-situ temperature. This changes the
88        isomip tests => update tests
89    o add a flag writePickupAtEnd (default=true) to be able to suppress
90      writing a pickup at the last timestep
91    o tools/mpack-1.6 :
92      - disable automake (not working) and autoconf (not needed).
93      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
94        also cleaner with much less compilation warnings.
95    o pkg/profiles:
96      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
97      (for "less than 32 characters name" compiler requirement)
98    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
99      conditions that have a different sampling frequency than S/T/U/V obcs
100    o pkg/diagnostics (stats-diags):
101      - fix global Min/Max in case 1 processor get only empty tiles
102    o genmake2: replace (4 times)
103         make genmake_tc_1.o >> genmake_warnings 2>&1
104      with
105         COMM="$CC $CFLAGS -c genmake_tc_1.c"
106         echo $COMM >> genmake_warnings
107         $COMM >> genmake_warnings 2>&1
108      to make genmake2 always see the value of CC as specified in the optfile.
109    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
110      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
111      - modify verification advect_cs test to test SOM-advection on CS-grid.
112    o pkg/ctrl:
113      - Rewrite of ctrl_map_ini_ecco.F,
114        introducing a generic routine (ctrl_map_ini_gen.F).
115      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
116    
117    checkpoint59n
118  o pkg/diagnostics: for large number of diagnostics, store diagnostic mate  o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
119    number in dedicate array "hdiag":    number in dedicate array "hdiag":
120    - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST    - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
