Abstract
A technique for parallel registration of lidar signals in photon counting and charge accumulation modes at the Siberian lidar station of Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences (SLS) is described in detail. A device is designed and experimentally tested for recording lidar signals with the use of the combined technique at the unique SLS lidar. During the experimental testing of the device, the limits of applicability of the technique suggested to regular measurements of the vertical distribution of air temperature based on lidar signals of purely rotational Raman spectra are determined. The comparison between the lidar and satellite measurements shows their good agreement, which proves the high efficiency of the combined technique and confirms the capability of deriving the vertical distribution of atmospheric temperature throughout the altitude range of the primary mirror of the Raman lidar of SLS.
