[ferret_users] Integrating over irregular regions

["Balaguru, Karthik" <karthiknaidu@xxxxxxxxxxxx>]

   Hi all,

      Is there a way in which we can integrate over an irregular region? Let's say I have a region in the shape of a parallelogram whose 4 corner co-ordinates are (longitude,latitude) respectively. How can I integrate a variable, say temperature over this region? Thanks a lot!
