A method for the retrieval of the aerosol scattering coefficient profiles in boundary layer is presented. A bistatic lidar system (CCD Lidar) with charge coupled device (CCD) as the detector and laser as transmitter is constructed. Aerosol scattering images of a horizontal laser beam and a vertical laser beam from ground to 1.2 km are imaged based on the CCD lidar system. The relative atmospheric scattering phase function (SPF) can be obtained by the aerosol scattering image of the horizontal laser beam, and the aerosol extinction coefficient (AEC) profile is inverted using the relative SPF. The AEC measured by CCD lidar has shown good agreement with that measured by double wavelength polarization lidar (DWPL) in 400 m and 600 m. Four nighttime AEC profile contours observed in Hefei are given. CCD lidar needs no overlap correction, it has a high spatial resolution of 0.032 m/pixel, and is expected as a potential technique of aerosol detection in boundary layer.
