4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o Refresh tutorial_global_oce_biogeo, notably:
8      - change bathymetry (put back seamounts in ACC, use hFacs)
9      - change EOS (POLY3 --> JMD95Z)
10      - use Bryan-Lewis vertical diffusivity
11      - use multidimensional advection
12      - remove old virtual virtual in dic pkg, now done through ptracer pkg
13      - change a couple of parameters in dic pkg
14    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
15    o pkg/obcs: change default to OBCSfixTopo = .true.,
16      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
17      - replace "debugMode" with "debugLevel .GE. debLevB"
18    o implementation of TAF directives for gchem,cfc,dic
19    o remove "exp5" (replaced by tutorial_deep_convection).
20    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
21      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
22      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
23      --> changes results in exp4, seaice_obcs
24    o tutorial_deep_convection :
25      update the set-up and increase resolution and domain size ; start
26      from pseudo initial conditions = output at t=120mn in order to see
27      something happening when running testreport.
28    o pkg/seaice: add os7mp as an advection scheme
29                  add check for advection schemes
30                  add a flag for restoring T and S underneath sea ice
31    o pkg/my82: add netcdf-support and diagnostics
32    o thsice pkg:
33      - Now hsMax limits snow height by turning it into ice following
34        flooding scheme (and now conserving energy)
35      - Slight rewriting of the formula in thsice_calc_thick.F
36      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
37      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
38    
39    checkpoint59p
40    o gchem / dic / cfc :
41      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
42      - add new parameter files: "data.dic" & "data.cfc" ;
43      - various re-arrangement in initialisation & header file ;
44      - fix tutorial_global_oce_biogeo for multi-threaded test.
45    o pkg/dic: test for "pickup_dic" file when restarting ;
46      if no pickup-file, can restart with a re-initialised pH (same as it did
47      before) providing pickupStrictlyMatch is set to False.
48    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
49      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
50    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
51      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
52    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
53     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
54       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
55    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
56       scheme to use for vorticty-term ;
57     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
58       (with default selectVortScheme, return to original discretisation)
59     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
60    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
61    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
62      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
63      also fix diagnostics VISCAHW & VISCA4W.

66  o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).  o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
67  o change the loop ordering in most gad_*_adv_x.F to improve vectorization:  o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
