     Notes on tags used in MITgcmUV
     ==============================
 
+o move state variable diagnostics to the beginning of the time step ;
+  (note: still needs some work specially for snap-shot diagnostics)
+  duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
+
+checkpoint57c_post
+o Change testing option (-ieee) to get closer agreement between g77 & ifort
+o generate new output.txt files on faulks with g77 & the new -ieee option
+checkpoint57c_pre
+
+o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
+  update output.txt of exp. global_ocean.90x40x15
+o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer 
+  results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
+o add saltFlux(+File) forcing capability with periodicExternalForcing
+o allow to use pkg diagnostics for GM-Redi & ThSIce output
+o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
+o improvements for the MNC output from DIAGNOSTICS:
+  - correct handling of the unlimitied dimension
+  - all dims now have associated coordinate variables
+  - variables located at U, V, and Corner ("Z") points are now written
+    with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that 
+    *all* data points are output
+o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
+o added pkg/seaice/seaice_monitor.F
+o mdsio_readfield.F can now read files visible only to master MPI process.
+o pkg/seaice: some test code for ice-modified ocean stress
+o exf_getffields interpolation defaults to bilinear for all scalar forcing
+  fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
+  spurious negative numbers for precipitation and humidity.  Will cause
+  some small numerical differences for integrations using pkg/exf/exf_interp.F.
+o pkg/ctrl/
+  * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
+    May be enabled via doPackDiag
+  *  introduce z-scaling of 
+     + gradient (doZscalePack) and 
+     + control (doZscaleUnpack)
+o pkg/mdsio/
+  * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
+  * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
+
+checkpoint57b_post
+o simplify options in diagnostics_fill arguments (remove weird combinations)
+o fix MNC coordinate variables so that they now contain per-face index
+  values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in 
+  general, EXCH2 grids are only aligned to a "local" coordinate system
+o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
+o Implement instantaneous output within pkg diagnostics:
+  setting a negative frequency in data.diagnostics produces
+ "snap-shot" output (as opposed to time-average if freq > 0)
+o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
+  NOTE: change ptracer diagnostics name: use 2 characters to work with 
+        more than 9 tracers. Add also diagnostics of advect & diffus flux.
+o more CF compliance: convert all MNC 'iter' variables to 'T' so that it 
+  becomes the coordinate variable for the 'T' dimension
+o add CF-style coordinate variables to MNC
+  - just a first cut:  numbers are meaningless on the cubesphere and 
+    missing along the T axis but otherwise it works!
+o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
+o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
+o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
+  this is based directly on what the model compute, so that the content of
+  each diagnostics might be affected by switching options (e.g., implicitDiffusion)
+o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
 o clean up build options files for SunOS, in particular 
   - remove -traditional from xmakedepend
   - change -xarch=v9 to -xarch=native for f77
