Re: error reading grib data

Dear Yan Mi,

In order to do the conversion properly, NCL needs to know what type of
file you're converting. Even though you don't have a file extension
in your file name, you can add one when you call ncl_convert2nc:

    ncl_convert2nc levelsECHAM64010_a10_1000001.grb

What NCL will do is first look for a file called
"levelsECHAM64010_a10_1000001.grb". If it doesn't see one, it then
looks for a file called "levelsECHAM64010_a10_1000001" and tries to
open it as a grib file.
