Elastic lidar observations of profiles of the aerosol extinction, backscattering coefficients, and the lidarratio have been performed in Beijing. The elastic lidar transmitts wavelengths of 532 and 355 nm. Themeasurement altitude can reach up to 6 km. The similarity of the extinction and backscattering profilessuggests a close relation between the mean transmission and reflection properties. The lidar ratio on July22, 2008 varied from 10 to 30 sr with the mean value of 20 sr. The profiles of the aerosol propertiesindicate the cirrus at 6-km altitude and a well-mixed boundary layer from July 22 to 24, 2008. Thedetected boundary layer also agrees well with the high and stable ozone concentration obtained from thedifferential optical absorption spectroscopy (DOAS) system.
