POST-PROCESSING
It runs on many different operating systems including Solaris, AIX, IRIX, Linux,
MacOSX, Dec Alpha, and Cygwin/X running on Windows. The NCL binaries are freely
available at: http://www.ncl.ucar.edu/Download/
To read more about NCL, visit: http://www.ncl.ucar.edu/overview.shtml
Necessary software
NCL libraries version 5.1.0 or higher.
Environment Variable
Set the environment variable NCARG_ROOT to the location where you installed the
NCL libraries. Typically (for cshrc shell):
.hluresfile
setenv NCARG_ROOT /usr/local/ncl
Create a file called .hluresfile in your $HOME directory. This file controls the color /
background / fonts and basic size of your plot. For more information regarding this file,
see: http://www.ncl.ucar.edu/Document/Graphics/hlures.shtml.
NOTE: This file must reside in your $HOME directory and not where you plan on
running NCL.
Below is the .hluresfile used in the example scripts posted on the web (scripts are
available at: http://www.mmm.ucar.edu/wrf/users/graphics/NCL/NCL.htm). If a different
color table is used, the plots will appear different. Copy the following to your
~/.hluresfile. (A copy of this file is available at:
http://www.mmm.ucar.edu/wrf/OnLineTutorial/Graphics/NCL/.hluresfile)
*wkColorMap : BlAqGrYeOrReVi200
*wkBackgroundColor : white
*wkForegroundColor : black
*FuncCode : ~
*TextFuncCode : ~
*Font : helvetica
*wkWidth : 900
*wkHeight : 900
NOTE:
If your image has a black background with white lettering, your .hluresfile has
not been created correctly, or it is in the wrong location.
