wradlib.atten.pia_from_kdp#
- wradlib.atten.pia_from_kdp(kdp, dr, gamma=0.08)[source]#
Retrieving path integrated attenuation from specific differential phase (Kdp).
The default value of gamma is based on [Carey et al., 2000].
- Parameters:
kdp (
numpy.ndarray
) – array specific differential phase Range dimension must be the last dimension.dr (
float
) – gate length (km)gamma (
float
) – linear coefficient (default value: 0.08) in the relation between Kdp phase and specific attenuation (alpha)
- Returns:
output (
numpy.ndarray
) – array of same shape as kdp containing the path integrated attenuation
