Research of air pollution impact of straw burning based on MODIS

MODIS is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. It can view one place about two times a day and has been widely used for biomass burning monitoring. This paper took use of MODIS data to research on the air pollution impact of straw burning. Firstly, this paper introduced the detection method of the fire points of straw burning based on MODIS data. Then combining with GIS buffer tool and statistic method, it analyzed the relationship between the fire points of straw burning within butter area and the air quality. Finally, it studied the air pollution impact from the straw burning integrating with atmospheric data in the research area of North China. It showed that the fire points within 700 and 800 km buffer areas had better accordance with API values, and the air pollution had some connections with the unfavorable atmospheric diffusion factors.
