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

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.
