Estimates rainfall rate using different relations between R and the polarimetric variables depending on the hydrometeor type.
radar (Radar) – Radar object.
alphazr, betazr (floats, optional) – Factor (alpha) and exponent (beta) of the z-r power law for rain.
alphazs, betazs (floats, optional) – Factor (alpha) and exponent (beta) of the z-s power law for snow.
alphaa, betaa (floats, optional) – Factor (alpha) and exponent (beta) of the a-r power law. If not set the factors are going to be determined according to the radar frequency.
mp_factor (float, optional) – Factor applied to z-r relation in the melting layer.
refl_field (str, optional) – Name of the reflectivity field to use.
a_field (str, optional) – Name of the specific attenuation field to use.
hydro_field (str, optional) – Name of the hydrometeor classification field to use.
rr_field (str, optional) – Name of the rainfall rate field.
main_field (str, optional) – Name of the field that is going to act as main. Has to be either refl_field or kdp_field. Default is refl_field.
thresh (float, optional) – Value of the threshold that determines when to use the secondary field.
thresh_max (Bool, optional) – If true the main field is used up to the thresh value maximum. Otherwise the main field is not used below thresh value.
rain (dict) – Field dictionary containing the rainfall rate.
