wradlib.zr.ZRMethods.z_to_r#
- ZRMethods.z_to_r(**kwargs)[source]#
Conversion from reflectivities to rain rates.
Calculates rain rates from radar reflectivities using a power law Z/R relationship Z = a*R**b
- Parameters:
obj (
xarray.DataArray
) – Corresponds to reflectivity Z in mm**6/m**3- Keyword Arguments:
Note
The German Weather Service uses a=256 and b=1.42 instead of the Marshall-Palmer defaults.
- Returns:
output (
xarray.DataArray
) – rainfall intensity in mm/h
