pyart.retrieve.compute_spectral_power#

pyart.retrieve.compute_spectral_power(spectra, units='dBADU', subtract_noise=False, smooth_window=None, signal_field=None, noise_field=None)[source]#

Computes the spectral power from the complex spectra in ADU. Requires key dBADU_to_dBm_hh or dBADU_to_dBm_vv in radar_calibration if the units are to be dBm

Parameters:

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

  • units (str) – The units of the returned signal. Can be ‘ADU’, ‘dBADU’ or ‘dBm’

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

  • smooth_window (int or None) – Size of the moving Gaussian smoothing window. If none no smoothing will be applied

  • signal_field, noise_field (str, optional) – 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:

pwr_dict (field dictionary) – Field dictionary containing the spectral power
