wradlib.atten.pia_from_kdp(kdp, dr, gamma=0.08)¶ 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 (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- kdp (
