- pyart.retrieve.est_rain_rate_kdp(radar, alpha=None, beta=None, kdp_field=None, rr_field=None)[source]#
Estimates rainfall rate from kdp using alpha power law.
radar (Radar) – Radar object.
alpha, beta (floats, optional) – Factor (alpha) and exponent (beta) of the power law. If not set the factors are going to be determined according to the radar frequency.
kdp_field (str, optional) – Name of the specific differential phase field to use.
rr_field (str, optional) – Name of the rainfall rate field.
rain (dict) – Field dictionary containing the rainfall rate.
