北京区域2013严重灰霾污染的主被动遥感监测

Joint use of active and passive remote sensing for monitoring of severe haze pollution in Beijing 2013

结合2013年1月北京区域严重灰霾污染,介绍了太阳-天空辐射计、激光雷达、多波段CCD相机等遥感监测手段,分析了地-空基、主-被动等遥感方法获得的灰霾气溶胶特性遥感结果,讨论了不同遥感监测手段的特点及联合使用,结果表明:主动遥感手段在严重污染、夜间等情况下具有观测优势,而被动遥感信息含量大,具有获得气溶胶复杂特性参数的能力;地面遥感点、垂直分布线监测数据与卫星遥感的面观测数据相结合,可以初步实现灰霾的主被动遥感立体监测。

Focusing on the serious haze event in January 2013 in Beijing, we analyzed remote sensing results of haze aerosol properties based on passive-active joint monitoring approaches. The analyses show that the active remote sensing approaches have advantages during the high pollution cases or the nighttime, while the passive approaches provide more information for aerosol characterization. By joint use of ground-based site, vertical profile, and satellite coverage monitoring, one can preliminarily realize the stereoscopic observation of haze aerosols.
