pyart.retrieve.calculate_snr_from_reflectivity#

pyart.retrieve.calculate_snr_from_reflectivity(radar, refl_field=None, snr_field=None, toa=25000.0)[source]#

Calculate the signal to noise ratio, in dB, from the reflectivity field.

Parameters:

  • radar (Radar) – Radar object from which to retrieve reflectivity field.

  • refl_field (str, optional) – Name of field in radar which contains the reflectivity. None will use the default field name in the Py-ART configuration file.

  • snr_field (str, optional) – Name to use for snr metadata. None will use the default field name in the Py-ART configuration file.

  • toa (float, optional) – Height above which to take noise floor measurements, in meters.

Returns:

snr (field dictionary) – Field dictionary containing the signal to noise ratio.
