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