大气气溶胶光学厚度遥感研究概况

A Review of Remote Sensing for Aerosol Optical Depth

大气气溶胶是影响气候变化的重要因子之一,利用遥感手段不仅可以获得气溶胶的分布信息,也可以得到相关的气溶胶光学特性参数。本文阐述了国内外气溶胶遥感的发展动态,介绍了气溶胶遥感的基本情况及气溶胶光学厚度反演的几种方法,提出了存在的问题并对今后的研究进行了展望。

Atmospheric aerosol is one of the most important factors which has influence on climate change. It can gain not only the aerosol distribution information but also the aerosol optical property parameters through the methods of remote sensing. The status in quo of aerosol remote sensing research home and abroad was introduced briefly in the paper, and several kinds of methods for aerosol optical depth retrieval and validation were stated in detail, and at last some prospect for aerosol optical depth retrieval was suggested.
