Je vois que tu es en plein dans les données TIGGE avec grads. Tu pourras aider Tidiane la-dessous. Je lui ai dit aussi de voir les données TIGGE.<br><br><div class="gmail_quote">2012/3/13 Ousmane Ndiaye <span dir="ltr"><<a href="mailto:ousmane@iri.columbia.edu">ousmane@iri.columbia.edu</a>></span><br>

I have TIGGE data in grib2 format I used ncl_convert2nc to convert the file to netcdf format but grads seems not liking it is there anyway to make it works.<br>
The file has : 14 runs, 9 leadtime, and 184 starting days over 121x121 grid<br>
