I'm quite accustomed to viewing WRF output in Grads. I used ARWpost as well. It worked for my system, so I didn't have to worry about opening most netCDF files directly. However, I have had to open them recently. I had the same problem, so I wrote a full-on control file for the netCDF file. The page Jennifer linked contains links to instructions for writing a descriptor file for your WRF output so you can view it in Grads. If you have any problems with that, I can help you.<br>
<br>As far as the reason the error comes with sdfopen, that remains a mystery to me since lat/lon data are included in standard WRF output.<br><br>Jeff Duda<br><br><div class="gmail_quote">On Tue, Feb 28, 2012 at 1:24 PM, Jennifer Adams <span dir="ltr"><<a href="mailto:jma@cola.iges.org">jma@cola.iges.org</a>></span> wrote:<br>
