Recently the German national weather service (DWD) published lots of data. I am especially interested in the 5 minutes radar data stored at:
https://opendata.dwd.de/weather/radar/composit/wx/ or https://opendata.dwd.de/weather/radar/composit/pg/
However, this folder only contains the data for the last 2 days. Does anyone knows how to get older versions of that data? There is older data on the server but only with hourly data, but I need it in 5 (or 10) minutes resolution.
