pyart.retrieve.compute_signal_power(radar, lmf=None, attg=None, radconst=None, lrx=0.0, lradome=0.0, refl_field=None, pwr_field=None)[source]#

Computes received signal power OUTSIDE THE RADOME in dBm from a reflectivity field.

Parameters:

  • radar (Radar) – radar object

  • lmf (float) – matched filter losses

  • attg (float) – 1-way gas attenuation

  • radconst (float) – radar constant

  • lrx (float) – receiver losses from the antenna feed to the reference point (positive value) [dB]

  • lradome (float) – 1-way losses due to the radome (positive value) [dB]

  • refl_field (str) – name of the reflectivity used for the calculations

  • pwr_field (str) – name of the signal power field

Returns:

s_pwr_dict (dict) – power field and metadata
