I need to find the EOF from  Extended Reconstructed Sea Surface Temperature
data set version 3b data. I’m new with NCL, I find the anomaly and need to
weight the anomaly matrix x by square root of grid cell area. Can any one
help to get the proper way….

I used
rad    = 4.*atan(1.)/180.
clat   = Anom&lat
clat   = sqrt( cos(rad*clat))
p=Anom
p=Anom*conform(Anomx,clat,1)

Where Anom is anomaly…. Is this the correct way to weight anomaly matrix by
square root of grid cell area.
