4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/mnc: have mnc create marginally meaning full coordinate variables
8      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
9    o pkg/mypackage:
10      - add example of read/write pickup for state-var ;
11      - add entry points to the main code for state-vars diags & write-pickup.
12    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
13      transitions for useExfYearlyFields
14      - add new subroutine that determines the file to read from for
15        use*YearlyFields = .TRUE. and .FALSE.
16      - add a verification experiment to global_with_exf that tests
17        useExfYearlyFields with USE_EXF_INTERPOLATION defined
18    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
19      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
20      subroutines (which could be generated from a template, because they are
21      almost identical), for now they are included in obcs_prescribe_read.F for
22      simplicity
23    o pkg/exf:
24      - add a little more diagnostic to exf_interp_read (in analogy to
25        mds_read_field, can be turned off with debugLevel < debugLevA=1)
26      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
27        ugly but fast by unrolling short inner loops, inserting a unroll=8
28        directive in routine lagran, and splitting a loop and making do while the
29        outermost loop (the latter requires the intoduction of index arrays)
30    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
31    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
32      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
33    o verification/seaice_obcs: updated for restart test and latest options
34    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
35      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
36      for now this is only available for the C-grid code and also within
37      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
38    
39    checkpoint59m
40    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
41      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
42    o gad_som : fix flux output (& diagnostics) to have same units as other  
43      advection scheme fluxes (was previously multiplied by deltaT).  
44    o added verification/seaice_obcs both to test seaice open boundaries
45      and to provide an example matlab scrpt for generating them
46    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
47    o pkg/salt_plume: clean up salt_plume_frac.F to
48      remove redundancy in PlumeMethod 1 and 4
49    o pkg/kpp: added saltplume diagnostics
50    o pkg/obcs and pkg/seaice:
51      - do not set uice and vice to zero when OB*icefile are unspecified
52      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
53      - moved seaice tracer obcs after call to seaice_growth
54    o pkg/salt_plume: added various options for salt plume depth
55      criterion and for vertical distribution of the salt
56    
57    checkpoint59l
58    o pkg/ptracers: new version of ptracers pickup:
59      read meta file and write only fields which are needed to restart.
60      ( same logic as main pickup file ; also using pickupStrictlyMatch )
61    o pkg/seaice:
62      - add timescale for melting due to warm mixed layer as a means of
63        setting SEAICE_availHeatFrac more conveniently
64      - add a CPP-flag/runtime parameter check for flooding algorithm
65      - reformulated availHeat in seaice_growth.F to be independent of AREA
66    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
67      unit changes
68    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
69    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
70      SX vector computer.
71    o pkg/seaice:
72      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
73        seaice forcing fields can now be read only through pkg/exf
74      - removed some unused halos
75    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
76    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
77      or U/VICE from U/VWIND before computing U/VSTRESS
78    
79    checkpoint59k
80    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
81      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
82    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
83      all experiments pass when compile with un-initialised var. checking option.
84    o added pkg/salt_plume
85    o script to test restart (for now, in MITgcm_contrib/jmc_script)
86    o pkg/seaice: new read/write pickup version.
87      read meta file and write only fields which are needed to restart.
88      ( same logic as main pickup file ; also using pickupStrictlyMatch )
89    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
90    o lab_sea.hb87: modify the domain & update output.hb87.txt :
91      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
92      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
93      process. Fixed here by closing the domain at the Northern boundary.
94    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
95    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
96      a set of consecutive levels in/from a 3-D array.
97    o pkg/ptracers:
98      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
99      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
100    
101    checkpoint59j
102    o in pkgs: dic, obcs, offline, rbcs:
103      standard way to compute coeff. for time interpolation between 2 time reccords
104      which retains full precision (& make results less dependent on compiler).
105      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
106    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
107      packages instead of reading ice cover and wind speed separately
108    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
109     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
110      to allow to compile customized code before the update)
111    o cleaning-up:
112      - fix CPP instruction syntax in pkg/obcs
113      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
114        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
115      - fix some threads issue in IO parts.
116  o pkg/dic:  o pkg/dic:
117    - add tons of "_d 0" (--> much better testreports !)    - add tons of "_d 0" (--> much better testreports !)
118     and then update outputs of tutorial_global_oce_biogeo     and then update outputs of tutorial_global_oce_biogeo
