Thanx for your immediate reply. I opened the file with the 6.0.0 version, but failed with the 6.5.0 version. I have to state though, that they are installed in different Linux machines.<br>

There should be a problem with Linux machine that hosts the 6.5.0 version, since other weird errors came up also (like segmentation faults when reading a file!). It seems that I should talk to my system admin...<br>

I also thank you for the conversion to NetCDF. However, I should be able to read the grib files, as I have to do that on a daily basis.</div>

<div>Hi,</div>
<div><br>
</div>
<div>I was able to read this file just fine with NCL 6.5.0. Are you using an older version of NCL? In any case, I've converted the file to NetCDF. I'll send that to you in a subsequent attachment.</div>
