have some issues with wrfout files from WRF model. I need to extract the polygon
average value of surface temperatures for each polygon using a shapefile
over southern California. I have the shapefiles with .shp, .dbf, .sbx,
.shx and .sbn. <br><br></div><div>I just able to plot the variables for different polygon (i.e, for different county) with the help of the sample script "shapefiles_11.ncl", but still I am facing problem how to make the average over the county and how to save the masked county data in .nc file or .csv file with latitude, longitude and variable.<br></div><div><br></div>I am waiting for any suggestions and help from the NCL experts how to resolve this issue. If any sample scripts are there it will be more appreciable.<br><br></div>with thanks and regards<br></div>Dipak<div><div class="gmail_signature"><div dir="ltr"><br></div></div></div>
