Hi Jiwen-

At the present time, the IDV needs to know how to geolocate the data.
That can either by by having the lat/lon information in the file, or
having some information about the map projection which can turn
the data from grid index to lat/lon.  In both cases, we recommend
adhering to the CF metadata conventions for the netCDF files:

So, if you can tailor your netCDF output to fit that convention,
then the IDV should read it.  If you want to provide a small,
sample file for us to look at, we can look it over and let you
know what is missing.
