Abstract

A new method for deriving atmospheric temperature from lidar measurements by utilizing Rayleigh-Brillouin scattering is introduced and implemented. An analytical model for Rayleigh-Brillouin line shapes in air is derived and used to determine atmospheric temperature from high spectral resolution lidar measurements. It is shown that in case of low aerosol content (4-12 km asl) the derived temperatures are in accordance with radiosonde measurements within ± 2 K.
