NCAR Graphics is no longer supported
NCAR no longer supports NCAR Graphics. It has been replaced by GeoCAT, which is a collection of Python packages related to the NCAR Command Language NCL, which also is no longer being developed. Consequently, NCAR Graphics software available NERSC is provided "as is" and without support, and may be removed at a future date. NERSC users are strongly encouraged to migrate their workflows to GeoCAT.
