Abstract

In this paper, through the Aerosol-lidar observation data located in the western suburbs of Hefei, a continuous aerosol pollution incident was observed from December 13 to 15, 2018. The range corrected signal and extinction coefficient profile continuously observed through fixed-point observation of ground-based lidar can accurately reflect the aerosol content and the characteristics of aerosol changes. The aerosol is mainly distributed below 1.5km. Through depolarization analysis of aerosol particles, the depolarization ratio is below 0.16, and it is concluded that the aerosol particles are spherical particles with a smaller particle size, and combined with the HYSPLIT model analysis, the main pollutants are transmission and industrial emissions of northern and eastern coastal cities in China.
