3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o allow to use pkg diagnostics for GM-Redi & ThSIce output
7    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
8    o improvements for the MNC output from DIAGNOSTICS:
9      - correct handling of the unlimitied dimension
10      - all dims now have associated coordinate variables
11      - variables located at U, V, and Corner ("Z") points are now written
12        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
13        *all* data points are output
14    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
15    o added pkg/seaice/seaice_monitor.F
16    o mdsio_readfield.F can now read files visible only to master MPI process.
17    o pkg/seaice: some test code for ice-modified ocean stress
18    o exf_getffields interpolation defaults to bilinear for all scalar forcing
19      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
20      spurious negative numbers for precipitation and humidity.  Will cause
21      some small numerical differences for integrations using pkg/exf/exf_interp.F.
22    
23    checkpoint57b_post
24    o simplify options in diagnostics_fill arguments (remove weird combinations)
25    o fix MNC coordinate variables so that they now contain per-face index
26      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
27      general, EXCH2 grids are only aligned to a "local" coordinate system
28    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
29    o Implement instantaneous output within pkg diagnostics:
30      setting a negative frequency in data.diagnostics produces
31     "snap-shot" output (as opposed to time-average if freq > 0)
32    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
33      NOTE: change ptracer diagnostics name: use 2 characters to work with
34            more than 9 tracers. Add also diagnostics of advect & diffus flux.
35    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
36      becomes the coordinate variable for the 'T' dimension
37    o add CF-style coordinate variables to MNC
38      - just a first cut:  numbers are meaningless on the cubesphere and
39        missing along the T axis but otherwise it works!
40    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
41    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
42    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
43      this is based directly on what the model compute, so that the content of
44      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
45    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
46    o clean up build options files for SunOS, in particular
47      - remove -traditional from xmakedepend
48      - change -xarch=v9 to -xarch=native for f77
49      - restore use of make (not gmake)
50      - add CC=gcc if using g77
51    o changes per discussion of AM, JMC, & EH3 today:
52      - move redundant "grid" variables out of "state" -- in preparation of
53        creating proper CF-style coordinate variables and in recognition
54        that any/all grid variables can be easily copied (eg. w/NCO) from
55        the grid files into any of the other NetCDF files
56      - *always* output grid variables with MDSIO (this will eventually be
57        changed)
58      - output MNC grid file if useMNC is true
59    o every instance of _END_MASTER() has been found and replaced with
60      _END_MASTER( myThid ) in order to satisfy certain picky Sun
61      preprocessors
62    o re-arrange diagnostics pkg initialisation:
63     - allow each package to extend the available diagnostics list
64     - add some checking and fix small problems (multi-threaded, ...)
65     - new S/R diagnostics_fill (replace fill_diagnostics):
66       look through the short list of active diag. (instead of the long list)
67       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
68    
69    checkpoint57a_post
70    o this set of changes restores TAMC compatibility
71      tested for global_ocean.90x40x15 adjoint on trough
72      (what a pain)
73    
74    checkpoint57a_pre
75    o some modifs in tools/build_options for sunos
76    o call ctrl_pack for ctrl at end for optimcycle=0
77    
78    checkpoint57
79    o add horizontal bi-harmonic viscosity for vertical velocity
80      - new parameter viscA4W (defaults to viscA4)
81      - affects only non-hydrostatic code
82      - to be done: no-slip lateral boundary conditions
83    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
84    o implement Implicit Vertical advection for pTracers
85    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
86      (implemented also for implicit vertical diffusion & advection)
87  o OBCS: extend application of tracer open boundary conditions  o OBCS: extend application of tracer open boundary conditions
88    to a strip beyond the boundary of width Olx/Oly    to a strip beyond the boundary of width Olx/Oly
89    o add call monitor to TAF set of required calls (flow directives)
90      and include in natl_box_adjoint
91    o untangle a few ifdefs related to cost, ctrl, autodiff
92      untangel a few ALLOW_ECCO_OPTIMIZATION
93    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
94      (theta2, salt2 in ecco_cost_weights)
95    
96  checkpoint56c_post  checkpoint56c_post
97  o OBCS as control variables  o OBCS as control variables
