摘　　要：利用偏振-米散射激光雷达探测对流层大气气溶胶的光学特性及其时空分布.介绍了该雷达的结构、技术参数和探测原理.获得了气溶胶的消光系数垂直廓线和光学厚度,并对这些结果进行了分析和讨论.结果表明,该雷达能较好地探测对流层大气气溶胶的光学特性及其时空分布.A polarization-Mie lidar （PML） has been used for measuring the optical properties of tropospheric aerosol. The fundamental principle of PML is briefly introduced. Overall structure and specifications of the PML, as well as data processing method, are described. We have obtained the profile of extinction coefficient of tropospheric aerosol and aerosol optical depth. The temporal-spatial distribution of aerosol extinction coefficient is also obtained through continuous detecting. The observing results of the cirrus clouds and aerosols show that the lidar has the ability to measure the optical properties of aerosols and their temporal and spatial variations.
