Hi Ousmane,<br>
<br>
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.<br>
<br>
<font color="#3333ff"><tt> grib_set -s editionNumber=1 </tt><tt><span
class="gmail-s1">1Sep2009.grib </span></tt><tt><span
class="gmail-s1">1Sep2009_GRIB1.grib</span></tt></font><br>
<br>
Then try to read the new file <span class="gmail-s1">1Sep2009_GRIB1.grib
in your NCL script.<br>
