摘　　要：臭氧和气溶胶是重要的大气组分,时空分布复杂多变.差分吸收激光雷达时空分辨率高,可自动连续运行,适用于臭氧和气溶胶的垂直探测.介绍了LGO-01型臭氧激光雷达的系统结构、主要参数和测量原理.将无人机与激光雷达测得的臭氧和PM_(2.5)浓度垂直廓线进行对比,两者在0.6 km以上基本一致,臭氧和PM_(2.5)的相对误差分别在5%和19%以内;而在0.6 km以下,激光雷达受限于几何因子的影响,误差较大.利用激光雷达对边界层臭氧浓度、气溶胶消光系数与退偏比进行连续观测,发现臭氧与气溶胶浓度呈现负相关性,并且较稀薄的沙尘所造成的光散射对臭氧生成具有促进作用.Ozone and aerosols are important components of atmosphere with complex and vari-able spatial and temporal distributions.The differential absorption lidar has high temporal and spatial resolution,can be operated automatically,and is suitable for continuous vertical observations of ozone and aerosols.The system structure,main parameters and detection principles of the LGO-O1 ozone li-dar are introduced.The ozone and PM_(2.5) profiles measured by lidar were compared to those detected by Unmanned Aerial Vehicle(UAV).Above O.6 km,the relative deviations of ozone and PM_(2.5) be-tween the two instruments were less than 5%and 19%respectively,showing a generally consistent pattern.However,below this height,the lidar measurements exhibit increased error due to the geomet-ric factors.Continuous lidar observations of ozone concentration,aerosol extinction coefficient,and de-polarization ratio in the boundary layer revealed a negative correlation between ozone and aerosol con-centrations.Furthermore,it was observed that light scattering induced by thin dust particles facilitates ozone formation.
