If the CMIP grids are rectilinear

region covering USA
   latS =
   latN =
   lonW =
   lonE =

   f = addfile(...)
   x = f->VAR(:,{latS:latN},{lonW:lonE})     ; 3d
   y = f->VAR(:,:,{latS:latN},{lonW:lonE})   ; 4d

; ***IF*** more specific maps are desired: read appropriate shape file
; READ CAREFULLY: http://www.ncl.ucar.edu/Applications/shapefiles.shtml

   fshp = addfile(...)
