大气气溶胶的卫星遥感及其在气候和环境研究中的应用

Review of Satellite Remote Sensing of Atmospheric Aerosols and Its Applications in Climate and Environment Studies

卫星遥感可以获得全球范围的大气气溶胶光学特性,目前国内外已有多颗卫星观测能够提供气溶胶特性的资料。本文综述性介绍国内外卫星遥感气溶胶特性方面的研究进展和成果,并讨论了卫星遥感资料在气候和环境研究领域中的应用。主要内容包括:极轨/静止卫星平台搭载的被动遥感传感器及其反演气溶胶特性的方法;星载激光雷达获取气溶胶光学特性的方法;国内外正在研发的新一代卫星主、被动气溶胶遥感探测器;卫星气溶胶产品在气溶胶辐射强迫、气候效应、大尺度污染输送、区域空气质量监测等研究中的应用。

Remote sensing of aerosols from satellites is the most convenient tool for providing global information on spatial and temporal distributions of atmospheric aerosols. Current satellite sensors have begun quotidian providing quantitative distributions of aerosol optical thickness. Progresses and research findings on satellite retrievals of aerosol optical properties are introduced in this paper with the emphasis on four aspects：（1） Aerosol passive sensors onboard different platforms of polar-and geostationary-satellites;（2） aerosol retrieval methods of satellite passive sensors;（3） aerosol retrievals from space-borne lidar;（4） the next-generation satellite passive and active sensors focusing on aerosol retrieval. In addition, the applications of satellite aerosol products in climate and environment studies are also reviewed in the paper.
