Abstract: This paper introduces the typical characteristics of AML-1 mobile lidar, which is the first mobile lidar of China. This lidar can be used to measure aerosols at daytime when receiver angle matches transmitter angle well and high transmission interference filter is used. It also can be used to measure aerosols at different zenith angle because it has 3D scanning device. All these may have great significance for realizing continual, simultaneous, large-ranged atmospheric pollution detecting. The results show great stability and reliability of AML-1 mobile lidar comparing with other lidars. Typical aerosol profiles and space-time distributing diagrams are shown and discussed at vertical，slant and 2D scanning aspects.
