wradlib - An Open Source Library for Weather Radar Data Processing

wradlib is designed to assist you in the most important steps of
processing weather radar data. These may include: reading common data
formats, georeferencing, converting reflectivity to rainfall
intensity, identifying and correcting typical error sources (such as
clutter or attenuation) and visualising the data.
