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 Java 
code 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.
