Hi Arlindo,
I am working with
*Grid Analysis and Display System (GrADS) Version 2.0.a9.oga.1

Config: v2.0.a9.oga.1 little-endian readline printim grib2 netcdf hdf4-sds
hdf5 opendap-grids,stn athena geotiff shapefile
*
I check the link you mentioned above, but I am confused that what am I type
instead of expression exist there. I am working with output data of RegCM4.1
and I do not know what exactly is the PSI, CHI, FISH_CHI and some another.

Any Idea?

Best Regards
