Re: Problems with average

You can specify two dimensions to average over in one call.
         e.g. averaged_Data = dim_avg_n( raw_data(:,lat|:,lon|:), (/1,2/) ) ;; will now average over the lat and lon dimensions.

from the ncl site: http://www.ncl.ucar.edu/Document/Functions/Built-in/dim_avg_n.shtml

        Example 4
Let z be defined as z(time,lev,lat,lon). Compute the time average at each latitude/longitude grid point.

    zAvg = dim_avg_n(z, (/0,1/)) ; ==> zAvg(nlat,nlon)
If metadata is desired use:
    zAvg = dim_avg_n_Wrap(z, (/0,1/)) ; ==> zAvg(nlat,nlon)
