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      - reformulated availHeat in seaice_growth.F to be independent of AREA
12    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
13      unit changes
14    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
15    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
16      SX vector computer.
17    o pkg/seaice:
18      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
19        seaice forcing fields can now be read only through pkg/exf
20      - removed some unused halos
21    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
22    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
23      or U/VICE from U/VWIND before computing U/VSTRESS
24    
25    checkpoint59k
26    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
27      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
28    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
29      all experiments pass when compile with un-initilised var. checking option.
30    o added pkg/salt_plume
31    o script to test restart (for now, in MITgcm_contrib/jmc_script)
32    o pkg/seaice: new read/write pickup version.
33      read meta file and write only fields which are needed to restart.
34      ( same logic as main pickup file ; also using pickupStrictlyMatch )
35    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
36    o lab_sea.hb87: modify the domain & update output.hb87.txt :
37      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
38      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
39      process. Fixed here by closing the domain at the Northern boundary.
40    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
41    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
42      a set of consecutive levels in/from a 3-D array.
43    o pkg/ptracers:
44      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
45      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
46    
47    checkpoint59j
48    o in pkgs: dic, obcs, offline, rbcs:
49      standard way to compute coeff. for time interpolation between 2 time reccords
50      which retains full precision (& make results less dependent on compiler).
51      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
52    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
53      packages instead of reading ice cover and wind speed separately
54    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
55     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
56      to allow to compile customized code before the update)
57    o cleaning-up:
58      - fix CPP instruction syntax in pkg/obcs
59      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
60        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
61      - fix some threads issue in IO parts.
62    o pkg/dic:
63      - add tons of "_d 0" (--> much better testreports !)
64       and then update outputs of tutorial_global_oce_biogeo
65    o pkg/mom_fluxform:
66      add a special version of momentum advection intended to conserve momentum
67      next to a bathymetry step or a coastline edge. (default = off = #undef)
68    o new read/write pickup version:
69      - for now, only implemented for main (mdsio) pickup file.
70      - write out only what is needed to restart; merge pickup_nh , pickup_ph
71        and main pickup together.
72      - read meta file; read only what is needed to restart; stop if a field
73        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
74        if it make sense (even if the restart is not perfect).
75      - if no meta file, assume that pickup to read corresponds exactly to
76        a pickup that would currently be written.
77      - read pickup written in the old format (until checkpoint59i) if it
78        recognizes an old meta file (no field-list).
79      - add a meta file in exp. which starts from a pickup: 2 cases:
80        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
81         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
82        b) a meta file describing the content of the associated pickup file
83         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
84    o pkg/mdsio & pkg/rw:
85      - new routine to read a meta file ; new set of routine to read
86        Multiple-fields file (with meta file).
87    o added open boundary conditions capability for seaice
88        HSNOW, HSALT, UICE, and VICE
