The wradlib project has been initiated in order to facilitate the use of weather radar data. It provides a common platform for research on new algorithms.



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