I use this for a few time then maybe some of this could be interested in this link... in French : http://gkforum.free.fr/phpBB2/viewtopic.php?t=140

Or if not you have the soft with an exemple to download.
>> http://gkforum.free.fr/archives/autres/ ... _UGRIB.exe (environ 2,7Mo)
>> http://gkforum.free.fr/archives/autres/ ... 102021.grb (environ 2,9Mo)

After if you want you can just register on http://www.grib.us/ to use fully the soft.

Bye...
