New GRADS user with ECMWF ERA40 data. Help!!!!

[Thomas Spengler]

Hi,

Alternatively, if you have an account at ECMWF, you could use their
routine: m2nc (just type help or man m2nc for more information, I think...)
which converts their grib files into GrADS readable NetCDF files. The
Grib file has to be in Lat/Lon though.
It works perfectly fine for me.

Cheers,
Thomas
