pyart.retrieve.compute_Doppler_width_iq

pyart.retrieve.compute_Doppler_width_iq(radar, subtract_noise=True, signal_field=None, noise_field=None, lag=1)

Computes the Doppler width from the IQ data

Parameters:

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

• subtract_noise (Bool) – If True noise will be subtracted from the signals

• lag (int) – Time lag used in the denominator of the computation

• signal_field, noise_field (str) – Name of the field in the radar which contains the signal and noise. None will use the default field name in the Py-ART configuration file.

Returns:

• width_dict (field dictionary) – Field dictionary containing the Doppler spectrum width

• Reference

• ———

• lag 1 algorithm based on – Time-Domain Computation of Mean and Variance of Doppler Spectra R. C. Srivastava, A. R. Jameson, and P. H. Hildebrand Journal of Applied Meteorology February 1979, Vol. 18, No. 2
