[ncl-talk] Fw: area average

[alesall]

Hi Ehsan, 

can you reorganize your data so that it is 2-dimensional, in latitude and longitude?
If your “var” measures something which varies in latitude and longitude, you need to figure out how the data in it is ordered/organized. 
Is the fastest dimension longitude or latitude?
You can use functions like “onedtond” to break down a vector of length nlon x nlat into a matrix of dimensions nlon, nlat.
And then assign names/values of latitude and longitude to the dimensions accordingly.

warm regards
