About wradlib

wradlib handles the unglamorous chain between a weather radar and usable rainfall data: reading the many native radar formats, clutter and attenuation correction, Z-R conversion, gauge adjustment, and georeferencing/gridding of the result — each step published, citable and inspectable.

Radar rainfall increasingly drives urban drainage design storms, model calibration and nowcasting inputs; wradlib is the established open toolkit for making radar data defensible rather than decorative. Well maintained by the openradar community, and it composes with pysteps when nowcasting is the goal.
