Ali,<br>I believe you need a data set that contains terrain height to be able to do that. Simply enter "d (height)" at the command prompt after opening the control file for the data set. Make sure you substitute the name for the variable that represents terrain height in the command. For example, in the WRF model, the variable is "hgt". I hope this helps.<br>
