<p class="MsoNormal">Hi Herb,<br>
<br>
You'll need to generate a data descriptor file for this. Note
that this model output<br>
is on a rectilinear grid (lat/lon) and sigma-coordinate
(vertical), so even with a
<br>
descriptor file you will need to make some approximations. On
the plus side you<br>
should be able to use the template option to get time-series
if needed.<br>
<br>
Jim<br>
<br>
Let me know if you need more details.<o:p></o:p></p>
