"In this example, we obtain and read the latest 30 minutes of available volumetric radar data from German Weather Service available at [opendata.dwd.de](https://opendata.dwd.de). Finally we do some plotting.\n",

"\n",
"This retrieves 6 timesteps of the 10 sweeps (moments DBZH and VRADH) of the DWD volume scan of a distinct radar. This amounts to 120 data files which are combined into one volumetric Cf/Radial2 like xarray powered structure.\n",
