xr.open_dataset

Making use of the xarray odim backend. We also need to provide the group. We use CfRadial2 group access pattern.

Plot Range vs. Time

Plot Range vs. Azimuth

We need to sort by azimuth and specify the y-coordinate.

backend_kwargs

Beside first_dim there are several additional backend_kwargs for the odim backend, which handle different aspects of angle alignment. This comes into play, when azimuth and/or elevation arrays are not evenly spacend and other issues.
