4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
8      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
9      for now this is only available for the C-grid code and also within
10      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
11    
12    checkpoint59m
13    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
14      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
15    o gad_som : fix flux output (& diagnostics) to have same units as other  
16      advection scheme fluxes (was previously multiplied by deltaT).  
17    o added verification/seaice_obcs both to test seaice open boundaries
18      and to provide an example matlab scrpt for generating them
19    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
20    o pkg/salt_plume: clean up salt_plume_frac.F to
21      remove redundancy in PlumeMethod 1 and 4
22    o pkg/kpp: added saltplume diagnostics
23    o pkg/obcs and pkg/seaice:
24      - do not set uice and vice to zero when OB*icefile are unspecified
25      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
26      - moved seaice tracer obcs after call to seaice_growth
27    o pkg/salt_plume: added various options for salt plume depth
28      criterion and for vertical distribution of the salt
29    
30    checkpoint59l
31    o pkg/ptracers: new version of ptracers pickup:
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:
35      - add timescale for melting due to warm mixed layer as a means of
36        setting SEAICE_availHeatFrac more conveniently
37      - add a CPP-flag/runtime parameter check for flooding algorithm
38      - reformulated availHeat in seaice_growth.F to be independent of AREA
39    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
40      unit changes
41    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
42    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
43      SX vector computer.
44    o pkg/seaice:
45      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
46        seaice forcing fields can now be read only through pkg/exf
47      - removed some unused halos
48    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
49    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
50      or U/VICE from U/VWIND before computing U/VSTRESS
51    
52    checkpoint59k
53    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
54      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
55    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
56      all experiments pass when compile with un-initialised var. checking option.
57    o added pkg/salt_plume
58    o script to test restart (for now, in MITgcm_contrib/jmc_script)
59    o pkg/seaice: new read/write pickup version.
60      read meta file and write only fields which are needed to restart.
61      ( same logic as main pickup file ; also using pickupStrictlyMatch )
62    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
63    o lab_sea.hb87: modify the domain & update output.hb87.txt :
64      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
65      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
66      process. Fixed here by closing the domain at the Northern boundary.
67    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
68    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
69      a set of consecutive levels in/from a 3-D array.
70    o pkg/ptracers:
71      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
72      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
73    
74    checkpoint59j
75    o in pkgs: dic, obcs, offline, rbcs:
76      standard way to compute coeff. for time interpolation between 2 time reccords
77      which retains full precision (& make results less dependent on compiler).
78      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
79    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
80      packages instead of reading ice cover and wind speed separately
81    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
82     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
83      to allow to compile customized code before the update)
84    o cleaning-up:
85      - fix CPP instruction syntax in pkg/obcs
86      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
87        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
88      - fix some threads issue in IO parts.
89    o pkg/dic:
90      - add tons of "_d 0" (--> much better testreports !)
91       and then update outputs of tutorial_global_oce_biogeo
92    o pkg/mom_fluxform:
93      add a special version of momentum advection intended to conserve momentum
94      next to a bathymetry step or a coastline edge. (default = off = #undef)
95    o new read/write pickup version:
96      - for now, only implemented for main (mdsio) pickup file.
97      - write out only what is needed to restart; merge pickup_nh , pickup_ph
98        and main pickup together.
99      - read meta file; read only what is needed to restart; stop if a field
100        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
101        if it make sense (even if the restart is not perfect).
102      - if no meta file, assume that pickup to read corresponds exactly to
103        a pickup that would currently be written.
104      - read pickup written in the old format (until checkpoint59i) if it
105        recognizes an old meta file (no field-list).
106      - add a meta file in exp. which starts from a pickup: 2 cases:
107        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
108         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
109        b) a meta file describing the content of the associated pickup file
110         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
111    o pkg/mdsio & pkg/rw:
112      - new routine to read a meta file ; new set of routine to read
113        Multiple-fields file (with meta file).
114    o added open boundary conditions capability for seaice
115        HSNOW, HSALT, UICE, and VICE
116    
117    checkpoint59i
118    o adjoint:
119      * fix multiDimAdvection adjoint
120        (partial recomputation problem by TAF for fVerT(:,:,kDown)
121        and comlev1 size definition (maxpass vs. max. number of tracers)
122      * verification/global_ocean.90x45x15 adjoint now tests
123        NLFS and multiDimAdvection using DST3 (=30)
124      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
125  o pkg/kpp: add "_d 0" to real constant (if missing);  o pkg/kpp: add "_d 0" to real constant (if missing);
