Retrieval of Aerosol Optical Properties based on Measurements of Lidar, Sun-Photometer, and CALIPSO at Wuhan, China

Studying optical properties of atmospheric aerosol is important because aerosol affects people around the world significantly. These effects strongly depend on the physical and optical properties of aerosol particles. In this paper, we propose to use lidar, sun-photometer, and CALIPSO synchronously, then present combined retrieval to investigate the optical properties of aerosol. The observations were performed at Wuhan during the period of December 2007 to May 2008. The primary results show that the proposed method improved the precision of aerosol optical depth effectively. Furthermore, long-term atmospheric and aerosol data could be obtained by consecutive observations. Also these data will be useful for future understanding about their environmental and climate effects.
