NCAR Graphics is a Fortran and C based software package for scientific
visualization. It consists of routines for drawing contours, maps,
vectors, streamlines, weather maps, surfaces, histograms, X/Y plots,
annotations, and more. It is provided by the National Center for
Atmospheric Research (NCAR)
NCL is a programming language designed specifically for the access,
analysis, and visualization of data. NCL can be run in interactive
mode, where each line is interpreted as it is entered at your
workstation, or it can be run in batch mode as an interpreter of
complete scripts. NCL is available for free in binary format for
several UNIX systems.

No settings are required to use NCAR or NCL. Simply run the binaries in /usr/local/bin and you'll be good to go. To use an older or non-default version of NCAR/NCL, refer to the versioned binaries, e.g., /usr/local/bin/ncar-pgi-6.0.0. Or you may use dotkit, e.g. use ncar-ncl-6.1.0 to automatically get the right version of your favorite NCL commands. Note that NCL is only included in the packages with "ncl" in their names.

The following man pages are available as part of the various dotkits (i.e., if you first type e.g. use ncar-gcc):
man ncargintro -- NCAR Graphics overview
man ncargf77 -- Command for compiling Fortran code that uses the NCAR Graphics low-level utilities
man ncargcc -- Command for compiling C code that uses the NCAR Graphics low-
man ncargex -- NCAR Graphics Fortran and C Low-Level Utility Examples
man ctrans -- a Computer Graphics Metafile ( CGM ) translator
man ncgm2cgm -- filter NCAR CGM to/from vanilla CGM
