[ncl-talk] NCEP/R2 sub-domain plot

[Dennis Shea]

Please read the documentation on data on rectilinear grids and
coordinate subscripting.

http://www.ncl.ucar.edu/Document/Manuals/language_man.pdf
Section 2.11

   latS = 20.0
   latN = 50.0
   lonR = 293.0
   lonL =40.00



   f = addfile("NCEP.R2.nc","r")

   x3 = f->X(:,{latS:latN}.{lonL:lonR})
   y4 = f->Y(:,",{latS:latN}.{lonL:lonR})

Ypu likely have to regrid to compare.
