Re: [netcdfgroup] storing sparse matrices data in NetCDF

Hi Ken,

In your example dataset, there are five values for the time coordinate.
However, the values of x, y, lat, lon, and elev do not seem to depend on
the values of time. Is this true in general for your data? If that's
true (while still allowing x, y etc. to vary from year to year, or file
to file), that makes packaging even simpler.
