近十来年杭州市大气气溶胶光学厚度卫星反演研究
On the Inversion of Aerosol Optical Depth of Hangzhou Based on the Satellite in the Past Decade
摘要
Abstract
Based on the daily MODIS data from 2003 to 2015 in Hangzhou ,a historical sequence of aerosol optical depth (AOD) with 500 m spatial resolution was inverted by using dense dark vegetation method .Combining with the ground observation data , the temporal and spatial distribution characteristics of AOD in Hangzhou were analyzed .The results showed that the absolute and relative error of AOD inversion results were 0 .16% ,33 .08% on average ,respectively .The annual average of AOD had a relatively slight fluctuation during 2003-2015 in Hangzhou ,with the maximum in 2008 and the minimum in 2013 .The seasonal mean of AOD in spring and summer were higher than the value in autumn and winter , the seasonal average of AOD in winter was the lowest .The monthly mean of AOD showed an increasing trend from January to June and the peaking point was observed in June ,while the value dropped down in the next six months .In addition ,it was found that the distribution of AOD was featured by high value in northeast and low in southwest .The highest was mainly located in the centre of the city ,while the secondary high value area were in Jianggan District and east of Yuhang District and Xiaoshan District .关键词
