· ¡` ¡ Applications
o The NCAR Command Language (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.
o NCAR Graphics is a Fortran and C based software package for scientific visualization. NCAR Graphics is available for FREE as open source under the GNU Public License, and pre-compiled binaries are available for several UNIX systems. NCAR Graphics, a time-tested UNIX package, consists mainly of over two dozen Fortran/C utilities for drawing contours, maps, vectors, streamlines, weather maps, surfaces, histograms, X/Y plots, annotations, and more.

· ¡` ¡ NCL Functions
o NCL comes with many useful built-in functions and procedures for processing and manipulating data. There are over 400 functions and procedures that include routines for:
o use specifically with climate and model data
o empirical orthogonal functions, Fourier coefficients, singular value decomposition, averages, standard deviations, sin, cosine, log, min, max, etc.
o retrieving and converting date information
o drawing primitives (lines, filled areas, and markers), wind barbs, weather map symbols, isosurfaces, and graphical objects
o file handling
o 1-dimensional, 2-dimensional, and 3-dimensional interpolation, approximation, and regridding
o facilitating computer analysis of scalar and vector global geophysical quantities (most are based on the package known as Spherepack)
o retrieving environment variables and executing system commands
o NCL supports calling C and Fortran external routines, which makes NCL infinitely configurable.
