中文摘要:激光雷达作为一种新兴的主动遥感探测工具,被广泛应用于大气遥感、环境监测等领域。星载激光雷达由于其较广的探测范围、较高的时空分辨率、可获得连续的廓线数据等优势,已经成为全球及区域气溶胶和云特性观测研究的强有力工具。本文总结了自2006年CALIPSO卫星发射以来,中国科学家在利用其开展沙尘气溶胶及污染研究方面的工作,重点阐述了沙尘气溶胶的时空分布、远距离传输、分类识别、光学特性、沙尘释放、辐射与气候效应,以及灰霾和烟尘特性等方面的最新研究成果。对以上研究成果的梳理,有助于深入理解中国在利用星载激光雷达开展沙尘与污染研究的水平,也为未来开拓中国自主研发星载激光雷达的遥感应用领域奠定了基础。

Research review on dust and pollution using spaceborne lidar in China
Abstract:As a new active remote sensing detection tool,lidar is widely used in many fields,such as atmospheric remote sensing,environmental monitoring and so on.With the advantages of large detection range,high spatial and temporal resolutions and continuous profile data,the spaceborne lidar has become a powerful tool for observing and studying aerosol and cloud properties at global and regional scales.This paper summarized the progresses of dust aerosols and pollution made by Chinese scientists since the launch of CALIPSO satellite in 2006.The results mainly focused on the following aspects:the spatial and temporal distributions and long-distance transmission of dust aerosols,the classification of natural and anthropogenic dust,the optical properties and emissions of dust aerosols,the dust-radiation-climate effects,as well as the haze and smoke characteristics.The review of the above research results will help us to have a deep understanding of the research level of dust and pollution in China by using the spaceborne lidar,and also will lay a research foundation for exploring the remote sensing application field of satellite-borne lidar independently researched and developed by China in the future.
