NCAR Command Language (NCL)

Description

NCAR Command Language (NCL) is a set of subroutines interfaced with the GKS base software. It is distributed by the National Center for Atmospheric Research (Boulder, Colorado). NCL allows the creation of plots (curves, histograms, contour plots, 3D visualisation, map contours, etc...)

Installed Version

• NCL is available only in the 6.6.2 parallel version and in an environment combining gcc/9.1.0 and intel-mpi/19.0.4

Usage

The module command allows access to the ncl product.

Note that only one version of ncl is available:

$ %%module avail ncl%%
ncl/6.6.2-mpi

Moreover, it can only be used in a single environment mixing gcc/9.1.0 with intel-mpi/19.0.4 as shown by the output of the display subcommand of module:

$ module display ncl
