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.

Check this old question I posted a while ago ...

The short answer is, if you want this data for longer periods of time (i.e. > 48 hrs), you have to get in touch with DWD. They will retrieve it for you from their archives ... for a fee. After I got this information, I set up an hourly cron job for the first of your links, because I was simply interested in having such data for a longer (yet not specific) period of time:

#!/bin/bash

su -c "lftp -c \"set ftp:list-options -a;
open ftp://opendata.dwd.de;
lcd /path/to/some/storage/DWD/wx_composit;
cd /weather/radar/composit/wx;
mirror --use-cache --verbose --allow-chown --allow-suid --no-umask --parallel=4\"" someusername

My "personal archive" reaches back to noon (UTC) 2017-08-05 (39k files, 36 GByte) ;)
