pyart.retrieve.est_rain_rate_zpoly(radar, refl_field=None, rr_field=None)[source]#

Estimates rainfall rate from reflectivity using a polynomial Z-R relation developed at McGill University.

Parameters:

  • radar (Radar) – Radar object.

  • refl_field (str, optional) – Name of the reflectivity field to use.

  • rr_field (str, optional) – Name of the rainfall rate field.

Returns:

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