- pyart.retrieve.atmospheric_gas_att(freq, elev, rng)[source]#
Computes the one-way atmospheric gas attenuation [dB] according to the empirical formula in Doviak and Zrnic (1993) pp 44. This formula is valid for elev < 10 deg and rng < 200 km so values above these will be saturated to 10 deg and 200 km respectively
- Parameters:
freq (float) – radar frequency [Hz]
elev (float or array of floats) – elevation angle [deg]
rng (float or array of floats. If array must have the same size as elev) – range [km]
- Returns:
latm (float or array of floats) – 1-way gas attenuation [dB]
