First of all, thanks for your time.</div><div class="gmail_default" style="font-family:garamond,serif;font-size:large"><br></div><div class="gmail_default" style="font-family:garamond,serif;font-size:large">I also use NCL to map data and I am sure this command will help in next steps of the study.</div>
<div class="gmail_default" style="font-family:garamond,serif;font-size:large">But at the moment, I want to produce dust maps in geopotential layers not vertical interpolation. As you know, we analyze atmospheric data more based on constant pressure layers. for example wind streams in 500 hPa. Since, I want to convert sigma layers to geopotential heights (in meters) and then depict dust particles in any single layers. </div>
<div class="gmail_default" style="font-family:garamond,serif;font-size:large">For instance: the concentration of dust particles in 850 hPa not in sigma layer 4,5, 15..... etc.</div><div class="gmail_default" style="font-family:garamond,serif;font-size:large">

You can use your geopotential heights at the sigma levels to interpolate your variables... I always do it with ncl, and it's very easy with the function<br>

Dear all, </div><div class="gmail_default" style="font-family:garamond,serif;font-size:large">
I am trying to map forecasted dust storms in different geopotential heights , not sigma levels, from wrfout file. </div>
<div class="gmail_default" style="font-family:garamond,serif;font-size:large">I used formula hPa=PH+PHB/g to calculate this parameter, but as you absolutely know it returns geo-heights in sigma levels. While I am trying to replace sigma level by geo-heights and sort forecasted data based on it. </div>
<div class="gmail_default" style="font-family:garamond,serif;font-size:large">Maybe it is a commonplace command, but unfortunately I could not find it on the net,</div><div class="gmail_default" style="font-family:garamond,serif;font-size:large">
