correlation between two nc files

[Robert Burgman]

Are you looking for the spatial correlation?
If the two .nc files use the same grid then simply use the scorr()
function.
If not you need to put them on a common grid .
The user defined function regrid2() is helpful for this.
This function was written by Mike Fiorino and can be found on the web.
Using the regrid2 function you define new variables.
set lat -90 90
set lon 0 359
define newvar1=regrid2(origvar1,2.5,2.5) for a 2.5 x 2.5 grid
define newvar2=regrid2(origvar2,2.5,2.5)    same grid!
now you can find the spatial correlation of the two newly define
variable since they are on a common grid.
d scorr(newvar1,newvar2,lon=-0,lon=359,lat=-90,lat=90)
