The results of comparison observation experiments between the 355 nm lidar and BAM-1020 particulate monitor laid on a 325 m tower of the Institute of Atmospheric Physics of the Chinese Academy of Sciences are given. Based on the data from 21 September 2011 to 21 October, good correlation between aerosol extinction coefficient by the lidar and PM2.5 particulate matter concentration is found. The linear regression model to establish the relationship between the extinction coefficient and the particulate matter concentration is used. The data of PM2.5 concentration measured by monitor laid on tower is used to study the inversion accuracy of the relational expression on the vertical height. The study results show that the correlation coefficients between lidar inversion PM2.5 and the measured values at 63, 80, 120 and 160 m are 0.9447, 0.9331, 0.9284 and 0.9308, respectively. The result shows that the lidar can detect the vertical distribution of particles. The lidar will be beneficial to study the spatial distribution and cross-border transportation problems of pollutants, as well as provide data to support policies and measurements of joint prevention and control of regional atmospheric.
