pyart.retrieve.compute_differential_reflectivity_iq(radar, subtract_noise=False, lag=0, signal_h_field=None, signal_v_field=None, noise_h_field=None, noise_v_field=None)[source]#

Computes the differential reflectivity from the horizontal and vertical IQ data

Parameters:

  • radar (IQ radar object) – Object containing the required fields

  • subtract_noise (Bool) – If true the noise is subtracted from the power

  • lag (int) – Time lag used to compute the differential reflectivity

  • signal_h_field, signal_v_field, noise_h_field, noise_v_field (str) – Name of the signal and noise fields. None will use the default field name in the Py-ART configuration file.

Returns:

zdr_dict (field dictionary) – Field dictionary containing the differential reflectivity
