An atmospheric aerosol lidar and its experiment in Beijing

An atmospheric aerosol lidar is introduced and its measuring experiment in Beijing is discussed in the paper. The vertical distribution of aerosol extinction coefficients and the relativity between aerosol and Black Carbon within summer planetary boundary layer over the observation site are shown in this paper. The experimental data indicates that the aerosol is almost trapped within PBL and troposphere layer is rather stable and BC is a important composition of aerosol in Beijing. The multi-layer structure of the aerosol distribution is obvious.
