pyart.correct.ptoa_to_sf#

pyart.correct.ptoa_to_sf(ptoa, pulse_width, wavelen, antenna_gain, coeff_band=1.2)[source]#

Converts the sun power at the top of the atmosphere (in dBm) into solar flux.

Parameters:

ptoa (float) – sun power at the top of the amosphere. It already takes into account the correction for antenna polarization
pulse_width (float) – pulse width [s]
wavelen (float) – radar wavelength [m]
antenna_gain (float) – the antenna gain [dB]
coeff_band (float) – multiplicative coefficient applied to the inverse of the pulse width to get the effective bandwidth

Returns:

s0 (float) – solar flux [10e-22 W/(m2 Hz)]
