pyart.retrieve.compute_rhohv(spectra, use_rhohv=False, subtract_noise=False, srhohv_field=None, pwr_h_field=None, pwr_v_field=None, signal_h_field=None, signal_v_field=None, noise_h_field=None, noise_v_field=None)[source]#

Computes RhoHV from the horizontal and vertical spectral reflectivity or from sRhoHV and the spectral powers

Parameters:

spectra (Radar spectra object) – Object containing the required fields
use_rhohv (Bool) – If true the RhoHV will be computed from sRho_hv. Otherwise it will be computed using the complex spectra
subtract_noise (Bool) – If True noise will be subtracted from the signals
srhohv_field, pwr_h_field, pwr_v_field, signal_h_field, signal_v_field,
noise_h_field, noise_v_field (str) – Name of the fields in radar which contains the signal and noise. None will use the default field name in the Py-ART configuration file.

Returns:

RhoHV_dict (field dictionary) – Field dictionary containing the RhoHV
