NetCDF question

[Don Hooper]

Kobi,

Well, like I told you privately, the sdfopen code isn't designed for
station data.  My foolish code assumes there exists more than one
value in the x and y vectors (your "lat" and "lon"), and probably
gets very confused as a result.  You might try writing an xdfopen-style
Data Descriptor File (DDF) (probably only need the DSET, XDEF, and YDEF
lines).  See the COLA GrADS documentation web site for the details.
