python-NGL and python-NIO

PyNGL and PyNIO provide Python interfaces to most of the graphics and file input/output functionality existing in the NCAR Command Language (NCL). A knowledge of NCL would give you a leg up in using these modules, but they are meant to be independent from NCL and used as a stand-alone suite of Python functions. In a few circumstances where the NCL documentation applies directly to PyNGL and PyNIO and there is no ambiguity, links are made to the NCL documentation from the PyNGL documentation. PyNGL and PyNIO represent recent developments in the evolution of a package that dates back several decades. Those who are interested can view the
