珠江三角洲地区的灰霾监控与卫星遥感

Satellite Remote Sensing for Haze Monitoring in Pearl River Delta Region

灰霾是目前珠江三角洲地区主要的空气污染之一,且呈逐年上升趋势。从灰霾的形成及特性分析着手,分析了现有监测方法及局限性,考虑到灰霾形成机理复杂、演变缓慢、区域大、边界模糊等特点,论述了卫星遥感应用于灰霾监控的可行性和必要性。结果表明,在现有的理化分析和一些新技术应用基础上,将卫星遥感作为一种补充,构建天地基站相结合的监控网络是十分必要的。

Haze is one of the main kinds of air pollution in the Pearl River delta region, and is in a significantly rising trend recently. According to the formation and characteristics of haze, the existing methods of air quality surveillance and limitations are analyzed in this paper. The complexity of formation mechanism, slow evolution, broad region, vague boundary and other features are discussed with respect to the feasibility and necessity of the application of satellite remote sensing for its monitoring and control. It is shown that a monitoring network should be built combined with space-based and ground-based stations, and that satellite remote sensing may serve as a complement to the physical-chemical analysis and new technologies.
