<p>Hi </p>
<p>I am using a WRF output file and I did the following changes "ONLY" to the code[ <a href="https://www.ncl.ucar.edu/Applications/Scripts/mask_9.ncl" class="OWAAutoLink" id="LPlnk10021" previewremoved="true">https://www.ncl.ucar.edu/Applications/Scripts/mask_9.ncl</a>]
. I want to mask the temperature in Malaysia using the shape file malay.shp. Can you kindly tell me what else do I need to change as currently I am not able to see the data masked within Malaysia. I will be grateful for your help</p>
