4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice:
8      - add timescale for melting due to warm mixed layer as a means of
9        setting SEAICE_availHeatFrac more conveniently
10      - add a CPP-flag/runtime parameter check for flooding algorithm
11    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
12      unit changes
13    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
14    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
15      SX vector computer.
16    o pkg/seaice:
17      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
18        seaice forcing fields can now be read only through pkg/exf
19      - removed some unused halos
20    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
21    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
22      or U/VICE from U/VWIND before computing U/VSTRESS
23    
24    checkpoint59k
25    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
26      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
27    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
28      all experiments pass when compile with un-initilised var. checking option.
29    o added pkg/salt_plume
30    o script to test restart (for now, in MITgcm_contrib/jmc_script)
31    o pkg/seaice: new read/write pickup version.
32      read meta file and write only fields which are needed to restart.
33      ( same logic as main pickup file ; also using pickupStrictlyMatch )
34    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
35    o lab_sea.hb87: modify the domain & update output.hb87.txt :
36      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
37      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
38      process. Fixed here by closing the domain at the Northern boundary.
39    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
40    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
41      a set of consecutive levels in/from a 3-D array.
42    o pkg/ptracers:
43      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
44      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
45    
46    checkpoint59j
47    o in pkgs: dic, obcs, offline, rbcs:
48      standard way to compute coeff. for time interpolation between 2 time reccords
49      which retains full precision (& make results less dependent on compiler).
50      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
51    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
52      packages instead of reading ice cover and wind speed separately
53    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
54     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
55      to allow to compile customized code before the update)
56    o cleaning-up:
57      - fix CPP instruction syntax in pkg/obcs
58      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
59        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
60      - fix some threads issue in IO parts.
61    o pkg/dic:
62      - add tons of "_d 0" (--> much better testreports !)
63       and then update outputs of tutorial_global_oce_biogeo
64    o pkg/mom_fluxform:
65      add a special version of momentum advection intended to conserve momentum
66      next to a bathymetry step or a coastline edge. (default = off = #undef)
67  o new read/write pickup version:  o new read/write pickup version:
68    - for now, only implemented for main (mdsio) pickup file.    - for now, only implemented for main (mdsio) pickup file.
