PyNGL/PyNIO

"PyNGL (pronounced "pingle") is a Python language module used to visualize scientific data, with an emphasis on high quality 2D visualizations. A working knowledge of Python is assumed. The NumPy extension module is used for array processing PyNIO is a Python module used for reading and writing files in several different data formats, including netCDF, netCDF 4, GRIB1, GRIB2, HDF 4, HDF-EOS 2 and HDF-EOS5, and CCM history files.

 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."
