Hi Lizhi,

I have mm5 model output files with a lambert conic projection and have used visad to view them. I can hopefully help out.Basically, you need to inspect the BigHeader sections, from which you can derive the parameters that Tom mentioned. I have Javacode for inspecting an mm5 file, including BigHeader, SubHeaders and data fields.


FWIW, I prefer the ucar.unidata.geoloc.projection classes in the IDV/Netcdf 
jars to the native visad.georef ones.
