The extinction-to-backscatter ratio, S1, is a crucial parameter for quantitative interpretation of lidar data. Because of the large and quick variation of S1 in APL, it is necessary to measure real-timely S1. A multi-instrument method is introduced for monitoring APL by lidar combined with some other instruments. Some experiments were completed for monitoring APL variation at Beijing, China in several periods during 2001-2004. The statistic of APL can be analyzed upon the data of aerosol profile, such as APL top-height, the total mass of aerosol loading in APL. %K lidar %K aerosol %K extinction %U www.iiisci.org/Journal/CV$/sci/pdfs/P969333.pdf
