Getting Started

NCL is a free interpreted computer language (like IDL,MatLab), developed at NCAR.It runs on many flavors of UNIX, Mac OSX, and Windows within a UNIX emulator shell.

1. NCL is already available on the SCD supercomputers, and the HAO network. If you want a personal copy for a laptop or other system, you can Download NCL after filling in a brief form.


2. You must put the following code in your .cshrc file in order to "see" NCL:
   
   
   • On DAVE and Dataproc:
     setenv NCARG_ROOT /contrib
   
   
   • On HAO:
     setenv NCARG_ROOT /opt/local
   
   
   • On Both: set path = ($path $NCARG_ROOT/bin)
   
   
3. You must put the following code in your .cshrc file in order to "see" the HAO NCL libraries:
   
   
   • On DAVE and Dataproc:
     setenv TGCMROOT /fs/projects/tgcm
     setenv HAO_NCL_LIB $TGCMROOT/ncl/lib
   
   
   • On HAO:
     setenv TGCMROOT /home/tgcm
     setenv HAO_NCL_LIB $TGCMROOT/ncl/web_ex/func_lib/


4. You should have a .hluresfile in every home directory of every machine on which you run NCL.
