[ncl-talk] reading s2s ecmwf forecast grib file

[Karin Meier-Fleischer]

Hi Ousmane,

sometimes the ECMWF data have mixed GRIB 1 and GRIB 2 records. To 
convert these files to GRIB 1 you can use the grib_api tools as Guido 
mentioned already.

   grib_set -s editionNumber=1 1Sep2009.grib 1Sep2009_GRIB1.grib

Then try to read the new file 1Sep2009_GRIB1.grib in your NCL script.
