Hi,<br><br>I tried to use<big><strong><span class="block"> "fish.gex" (GrADS Extension Library for Calculating Streamfunction/Velocity Potential</span></strong></big>) to calculate streamfunction from known u and v fields. I read through the website here: <a href="http://opengrads.org/doc/udxt/fish/fish.html">http://opengrads.org/doc/udxt/fish/fish.html</a><br>
It looks like this function can only apply to global lat/lon domain.<br>My data is in lat/lon coordinate already, but it is not global since my data is output from mesoscale model.<br>Whenever I used fish_psi(u,v) to get streamfunction, I get error messages "error from fish: rc=1000"<br>
I tried to narrow down my lat and lon range, and it still doesn't allow me to calculate.<br>Does anybody know how should I deal with it?<br>Thank you!<br><br clear="all">Ting-Chi<br>-- <br>Ting-Chi Wu<br>RSMAS/MPO (Ph.D student)<br>
