摘　　要：大气污染已成为全球性的环境污染问题之一,PM2.5和PM10已成为当前大气遥感研究的热点,以京沪穗为代表的特大城市更成为相关研究的重要焦点。通过对国内外相关文献的分析,以广州为例描述了地面站点监测的现状和不足,指出PM2.5遥感的关键问题为区域尺度气溶胶光学厚度垂直订正和区域尺度近地面消光系数湿度效应校正研究;通过空气质量模式系统进行相关研究,是包括PM2.5在内的大气颗粒物遥感的重要途径之一。Atmospheric pollution has been one of global environment pollution issues. PM2.5 and PM10 are the hot spots in remote sensing research of atmospheric particulates. The representative megacities in China, Beijing, Shanghai and Guangzhou, are the focus in related research field. Taking Guangzhou as an example, this paper analyzed the related domestic and international literatures, described the situation and limitation of the surface monitoring stations. It was pointed out that one of the important approaches of atmospheric particulate remote sensing including PM2.5 would be the regional atmospheric modeling system based on vertical correction model of airosol optical thinkness and moisture effect correction of near-surface extinction coefficient in regional scale.
