General usage information

NCL (the NCAR Command Language) is an interpreted languate designed specifically for scientific data analysis and visualization. It' supports NetCDF (v3/v4), GRIB (v1/v2), HDF (v4/v5), shapefile, ASCII and binary formats. Numerous analysis functions are built-in.

This module will add the various NCL commands to your PATH

NOTE: NCAR is deprecating support for NCL and is moving to Python and their supported Python modules as their officially supported scripting languate. Please start migrating your workflows.

In case you need to link against this library in your code, the following environmental variables have been defined:

• \$NCL_ROOT has been set to the root of the ncl installation
• \$NCL_LIBDIR points to the directory containing the libraries
• \$NCL_INCDIR points to the directory containing the header files

You will probably wish to use these by adding the following flags to your compilation command (e.g. to CFLAGS in your Makefile):

• -I\$NCL_INCDIR

and the following flags to your link command (e.g. LDFLAGS in your Makefile):

• -L\$NCL_LIBDIR -Wl,-rpath,\$NCL_LIBDIR
