Aerosols have been identified as one of the uncertainties in the evaluation of radiative forcing. Lidar is effective remote sensing tool for aerosols observation. The vehicle-mounted lidar was used to continuously observe the particle concentration in Anping County by combining fixed vertical detection and mobile navigation monitoring. The results of fixed detection are in line with the trend of air quality rising first and then falling in accordance with the trend of the Ministry of Environmental Protection. Mobile navigation detection can quickly and accurately locate the location of the pollution source. Finally, the results of navigation monitoring before and after spraying the dust suppressant are compared, and it is concluded that spraying the dust suppressant can effectively reduce the concentration of particulate matter.
