RADOLAN is abbreviated from the german RAdar-OnLine-ANeichung, which means Radar-Online-Adjustment.

Using it’s network of 17 weather radar the German Weather Service provides many products for high resolution precipitation analysis and forecast. A comprehensive product list can be found in chapter RADOLAN Product Showcase.

These composite products are distributed in the RADOLAN Binary Data Format with an ASCII header. All composites are available in Polar Stereographic Projection which will be discussed in the chapter RADOLAN Grid.

This notebook tutorial was prepared with material from the DWD RADOLAN/RADVOR-OP Kompositformat. We also wish to thank Elmar Weigl, German Weather Service, for providing the extensive set of example data and his valuable information about the RADOLAN products.
