xarray CfRadial1 backend#
In this example, we read CfRadial1 data files using the xradar
cfradial1
backend.
Data is also exported to ODIM_H5 and CfRadial2.

Load CfRadial1 Volume Data#
We use the functionality provided now by xradar
to read the CfRadial1 data into a DataTree.

, range
and time
. There will be variables like radar moments (DBZH etc.) and sweep-dependend metadata (like fixed_angle
, sweep_mode
etc.).
