大气光学 微脉冲激光雷达 气溶胶光学厚度 南京北郊 atmospheric optics micropulse lidar aerosol optical depth northern suburb of Nanjing
摘要
微脉冲激光雷达是探测气溶胶的有效工具.为了验证探测的准确度,对一台微脉冲激光雷达观测数据采用Fernald算法进行反演,得到了南京北郊上空的气溶胶光学厚度,并将反演结果同太阳光度计观测数据、喇曼-瑞利-米雷达观测数据和中分辨率成像光谱仪的标准气溶胶产品进行了比较.结果表明,它们之间具有一定相关性.微脉冲激光雷达是反演气溶胶光学厚度的有效手段,可以用于其它观测手段的地面验证.
Abstract
Micropulse lidar (MPL) is an effective tool for aerosol detection.To verify the accuracy of detection,MPL was used to calculate the aerosol optical depth (AOD) in the northern suburb of Nanjing with the Fernald inversion method.The inversion results were compared with those obtained with a sun-photometer,a Raman-Rayleigh-Mie lidar and a standard aerosol detection instrument (a moderate-resolution imaging spectroradiometer).The results show good correlation among them.The MPL is useful for AOD inversion and can be used to verify other measurement data effectively.
