rainymotion is a Python library for radar-based precipitation nowcasting based on optical flow techniques. The main idea is to provide a stack of open models which can serve as a transparent benchmark for further development of nowcasting techniques. An extensive verification study in Germany has shown that the
rainymotion models based on Dense optical flow are at least equivalent if not superior to state-of-the-art operational nowcasting techniques.
