Amulya,<br>Thank you for adding the new information. I can tell that the value of the script variable mix, which is given as 1573660000, cannot be right. Check line 2424 of your script code. That is where the variable mix is computed. Insert say statements for all the component variables there. With this kind of investigation you will eventually be able to discover the source of the error. My gut tells me one of the input variables you supplied to the script in the main function call plotskew() is not what the script is expecting it to be. I'm guessing it is the dewpoint variable. But I saw your control file and it appears there should not be a problem with that. Nonetheless, insert say statements to find out what the values are, then go from there. If you need help knowing what to do next or where to look, please ask.<br>

Amulya,<br>I looked through your script and I can't find the cause of the error. I've used this script on WRF-ARW output myself before (also postprocessed using ARWpost). I remember having some issues getting the script to run properly the first time, but I got around that somehow. The errors indicate that in this line<br>
<br>thetae=theta*exp((3.376/TLcl-0.00254)*mix*1.0+0.00081*mix)<br><br>one of theta, TLcl, or mix is not being computed correctly. I'm not sure which of those it is, although you could put SAY statements just above that line for each of the variables to see which it is. What I mean is, insert these lines<br>
say theta<br>say TLcl<br>say mix<br>Above the line I copied above. Then see what values get spit out. One of those is either a NaN of some sort or has characters where there should be numbers.<br><br><br>Jeff Duda<br><br>
