pyart.retrieve.ZtoR(radar, ref_field='reflectivity', a=300, b=1.4, save_name='NWS_primary_prate')[source]#

Convert reflectivity (dBZ) to precipitation rate (mm/hr)

Author: Laura Tomkins (lauramtomkins@gmail.com)

Parameters:

radar (Radar) – Radar object used.
ref_field (str) – Reflectivity field name to use to look up reflectivity data. In the radar object. Default field name is ‘reflectivity’. Units are expected to be dBZ.
a (float) – a value (coefficient) in the Z-R relationship
b (float) – b value (exponent) in the Z-R relationship

Returns:

radar (Radar) – The radar object containing the precipitation rate field
