Abstract :
On the eve of Beijing Olympic Games (BOG), frequent haze days had been extensively concerned by home and abroad. Ground-based and satellite remote sensing project was carried out to monitor haze distribution and intension by Chinese Academy of Sciences. Based on the assumption that surface reflectance vary slowly in a relative short period, the Haze Optical Thickness (HOT) retrieval model using MODIS data is established. Aerosol type is selected according to the ground experiment of haze particle composing in Central North China Plain. This model avoid that NASA Dense Dark Vegetation (DDV) algorithm couldn´t determine the radio of surface reflectance between middle-IR and visible channel on haze day. From Jun. 1st to Sep. 30th, 2008, AOT observed by sun photometer (CE318) on the ground was used to validate HOT, and it had shown good coherence.
