摘要：

In this paper, 3 km Moderate resolution Imaging Spectroradiometer (MODIS) aerosol products over Xuzhou and the surrounding area, including Jiangsu, Anhui, Henan and Shandong provinces in China, from July, 2002 to December, 2015 are collected and validated by the ground-based measured data from Xuzhou-CUMT site of Aerosol Robotic Network (AERONET). The validation result shows that the correlation coefficient of aerosol optical depth (AOD) between MODIS and AERONET data is 0.86 and the regression equation is y = 1.06x + 0.06. The monthly and seasonal average of 3 km MODIS AOD are calculated and charted. The results show that AOD in Xuzhou area is highest in summer and lowest in winter. The average of monthly AOD is about 0.82. After 2008 Beijing Olympic Games, AOD in Xuzhou increases again. Therefore, the sustained efforts should be made to improve air quality in Xuzhou area.
