Re: (no subject)

Hello

The ncl-talk_at_ucar.edu is the place to send NCL re;ated
questions. Please, do *not* send NCL questions to ncl-install.
That is for 'installation' questions.

wrfhelp should respond to your question.
However, the answer is "yes" you can open
multiple files in NCL

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRF_contributed.ncl"

begin
;************************************************
; open file and read in data
;************************************************
   f1 = addfile ("wrfout_d01_000000.nc", "r")
   f2 = addfile ("wrfout_d02_000000.nc", "r")
;************************************************
; Read perturbation geopotential at all times and levels
;************************************************
   x1 = f1->PH ; (Time, bottom_top, south_north, west_east)
   x2 = f2->PH

   diff = x2-x1
   copy_VarMeta(x1, diff)
   copy_VarCoords(x1, x2)

   printVarSUmmary(diff)
   printMinMax(diff, True)

See http://www.ncl.ucar.edu/Applications/wrflc.shtml
for plotting examples.
