摘要: 近些年来,气溶胶对环境的影响越来越受到人们的重视,气溶胶光学厚度(AOD)是表征气溶胶最重要的因子之一。本文研究基于2016年3月至9月的MODIS L1B数据,采用暗像元方法和6S辐射传输模型对江苏省徐州市的AOD进行遥感反演监测。基于反演的气溶胶光学厚度结果,对2016年徐州市AOD时空变化及差异特征进行了分析,结果显示不同地理单元的AOD均较为一致,其中7月的厚度值最大,5月次之,3月较小,4、6、8和9月最低;铜山县、邳州市、徐州市3个县市的AOD明显高于徐州地区的平均值水平,新沂和睢宁地区的AOD也相对较高,沛县、丰县等地区的AOD最低。

Abstract: In recent years,more and more attention has been paid to the influence of aerosol on the environment. Aerosol optical depth (AOD) is one of the most important factors to characterize aerosol. This study was based on the MODIS L1B data from March to September in 2016 and the AOD of Xuzhou city,Jiangsu province was remote sensing inversion monitored by dark pixel method and 6S radiation transmission model. Based on the results of inversion of AOD,the temporal and spatial variation and different characteristics of AOD in Xuzhou city in 2016 are analyzed. The analysis results show that the AOD values of the different geographic units are consistent rule,of which the thickness value is the largest in July,the second in May,the smaller in March,the lowest in April,June,August and September. The AOD values of Tongshan county,Pizhou city and Xuzhou city are obviously higher than the average level of Xuzhou area. The AOD values of Xinyi and Suining areas are relatively high,and the AOD of Peixian and Fengxian areas and so on are the lowest.

Key words: Xuzhou city, MODIS, aerosol optical depth, remote sensing monitoring
