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.

Parameters:

  • 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.

Returns:

rain (dict) – Field dictionary containing the rainfall rate.
