I opened them successfully in other platforms including all variables (e.g. u, v, theta, temp) but in GrADS only u is being shown. The other variables are being left out.<br>

endvars<br>
<br>
The error says gadxdf error: Missing or invalid dimension size. I am guessing the error is the xdef and ydef. Can you help me on this?<br>
<br>
Thanks.<br>
