<div dir="ltr">Hi there,<br><br>When you generate the fields via the ARWPOST you can specify the levels you want either in height levels or pressure levels. Then ARWPOST will do the interpolation job for you. Give a try.<br>

<p class="MsoNormal">Hello grads users,</p>
<p class="MsoNormal">I want to interpolate the filed o3 in the wrf output to the

I get the following error:</p>

Are these three lines correct:<br>

"run <a href="http://pinterp.gs" target="_blank">pinterp.gs</a>"<br>
"a = o3*1000"<br>
"d a" pinterp(a,Lev,1000)<br>
