This paper first studies the advantages and main observation methods of atmospheric particulate matter lidar in Regional large-scale measurement, and then discusses the measurement principle of lidar and two commonly used methods for inversion of aerosol extinction coefficient.Finally, the mobile observation system consisting of lidar-assisted vehicle particle monitor is used. Anping County is used as the research area.The lidar data of Anping County on September 15 to September 20, 2017 are obtained by means of the combination of navigation and fixed vertical monitoring.The results of fixed detection showes that foreign pollutants begin to be imported around 10 pm on the 15th, and the superimposed pollutants peakes around 2 pm on the 16th.The concentration of particulate matter gradually decreased after 2 pm on the 16th, which is in line with the trend of air quality rising first and then falling in accordance with the trend of the Ministry of Environmental Protection.According to the particle trajectory tracking map of the navigation area, the contaminant transport was analyzed Combined with the meteorological conditions at that time.
