4      ==============================      ==============================
5    
6    o exf_getffields interpolation defaults to bilinear for all scalar forcing
7      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
8      spurious negative numbers for precipitation and humidity.  Will cause
9      some small numerical differences for integrations using pkg/exf/exf_interp.F.
10    
11    checkpoint57b_post
12    o simplify options in diagnostics_fill arguments (remove weird combinations)
13    o fix MNC coordinate variables so that they now contain per-face index
14      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
15      general, EXCH2 grids are only aligned to a "local" coordinate system
16    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
17    o Implement instantaneous output within pkg diagnostics:
18      setting a negative frequency in data.diagnostics produces
19     "snap-shot" output (as opposed to time-average if freq > 0)
20    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
21      NOTE: change ptracer diagnostics name: use 2 characters to work with
22            more than 9 tracers. Add also diagnostics of advect & diffus flux.
23    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
24      becomes the coordinate variable for the 'T' dimension
25    o add CF-style coordinate variables to MNC
26      - just a first cut:  numbers are meaningless on the cubesphere and
27        missing along the T axis but otherwise it works!
28    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
29    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
30    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
31      this is based directly on what the model compute, so that the content of
32      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
33    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
34    o clean up build options files for SunOS, in particular
35      - remove -traditional from xmakedepend
36      - change -xarch=v9 to -xarch=native for f77
37      - restore use of make (not gmake)
38      - add CC=gcc if using g77
39    o changes per discussion of AM, JMC, & EH3 today:
40      - move redundant "grid" variables out of "state" -- in preparation of
41        creating proper CF-style coordinate variables and in recognition
42        that any/all grid variables can be easily copied (eg. w/NCO) from
43        the grid files into any of the other NetCDF files
44      - *always* output grid variables with MDSIO (this will eventually be
45        changed)
46      - output MNC grid file if useMNC is true
47    o every instance of _END_MASTER() has been found and replaced with
48      _END_MASTER( myThid ) in order to satisfy certain picky Sun
49      preprocessors
50    o re-arrange diagnostics pkg initialisation:
51     - allow each package to extend the available diagnostics list
52     - add some checking and fix small problems (multi-threaded, ...)
53     - new S/R diagnostics_fill (replace fill_diagnostics):
54       look through the short list of active diag. (instead of the long list)
55       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
56    
57    checkpoint57a_post
58    o this set of changes restores TAMC compatibility
59      tested for global_ocean.90x40x15 adjoint on trough
60      (what a pain)
61    
62    checkpoint57a_pre
63    o some modifs in tools/build_options for sunos
64    o call ctrl_pack for ctrl at end for optimcycle=0
65    
66  checkpoint57  checkpoint57
67  o add horizontal bi-harmonic viscosity for vertical velocity  o add horizontal bi-harmonic viscosity for vertical velocity
68    - new parameter viscA4W (defaults to viscA4)    - new parameter viscA4W (defaults to viscA4)
