4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o move from external_forcing_surf.F to ini_forcing.F
8      the p-coord. hack consisting in using pLoad to set phi0surf ;
9      update output of tutorial_global_oce_in_p (affected @ truncation level).
10    o Freshen up a bit hs94.1x64x5, notably:
11      remove rotationPeriod and tRef=5*0. (adjoint only), and add exactConserv=.TRUE.
12    o pkg/generic_advdiff:
13      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
14      applies to files where Temperature & Salinity 2nd Order moments are used.
15    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
16      this uses a dynamically allocated internal state data structure
17      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
18      and requires a fortran 90 compiler
19    
20    checkpoint59q
21    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
22       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
23    o Refresh tutorial_global_oce_biogeo, notably:
24      - change bathymetry (put back seamounts in ACC, use hFacs)
25      - change EOS (POLY3 --> JMD95Z)
26      - use Bryan-Lewis vertical diffusivity
27      - use multidimensional advection
28      - remove old virtual virtual in dic pkg, now done through ptracer pkg
29      - change a couple of parameters in dic pkg
30    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
31    o pkg/obcs: change default to OBCSfixTopo = .true.,
32      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
33      - replace "debugMode" with "debugLevel .GE. debLevB"
34    o implementation of TAF directives for gchem,cfc,dic
35    o remove "exp5" (replaced by tutorial_deep_convection).
36    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
37      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
38      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
39      --> changes results in exp4, seaice_obcs
40    o tutorial_deep_convection :
41      update the set-up and increase resolution and domain size ; start
42      from pseudo initial conditions = output at t=120mn in order to see
43      something happening when running testreport.
44    o pkg/seaice: add os7mp as an advection scheme
45                  add check for advection schemes
46                  add a flag for restoring T and S underneath sea ice
47    o pkg/my82: add netcdf-support and diagnostics
48    o thsice pkg:
49      - Now hsMax limits snow height by turning it into ice following
50        flooding scheme (and now conserving energy)
51      - Slight rewriting of the formula in thsice_calc_thick.F
52      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
53      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
54    
55    checkpoint59p
56    o gchem / dic / cfc :
57      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
58      - add new parameter files: "data.dic" & "data.cfc" ;
59      - various re-arrangement in initialisation & header file ;
60      - fix tutorial_global_oce_biogeo for multi-threaded test.
61    o pkg/dic: test for "pickup_dic" file when restarting ;
62      if no pickup-file, can restart with a re-initialised pH (same as it did
63      before) providing pickupStrictlyMatch is set to False.
64    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
65      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
66    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
67      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
68    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
69     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
70       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
71    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
72       scheme to use for vorticty-term ;
73     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
74       (with default selectVortScheme, return to original discretisation)
75     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
76    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
77    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
78      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
79      also fix diagnostics VISCAHW & VISCA4W.
80    
81    checkpoint59o
82    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
83    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
84      move a few statemens out the main loop into separate loops
85    o pkg/shelfice:
86      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
87        (kg/m^2/s), does not break tests, because in verification/isomip,
88        rhoConstFresh=rhoConst (by accident)
89      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
90      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
91        new file model/src/seawater.F, so that they are available for all pkgs.
92      - convert potential temperature into in-situ temperature. This changes the
93        isomip tests => update tests
94  o add a flag writePickupAtEnd (default=true) to be able to suppress  o add a flag writePickupAtEnd (default=true) to be able to suppress
95    writing a pickup at the last timestep    writing a pickup at the last timestep
96    o tools/mpack-1.6 :
97      - disable automake (not working) and autoconf (not needed).
98      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
99        also cleaner with much less compilation warnings.
100  o pkg/profiles:  o pkg/profiles:
101    rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg    rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
102    (for "less than 32 characters name" compiler requirement)    (for "less than 32 characters name" compiler requirement)
