Aerosol optical depth(AOD) datasets are used to describe and analyze air pollution.The association between satellite based AOD and air pollution monitored on the ground can be influenced by a number of factors.The relation between moderate resolution imaging spectroradiometer(MODIS) AOD and PM2.5in the Beijing-Tianjin-Hebei region was analyzed.The results showed a consistent spatial-temporal distribution of AOD and PM2.5.During November 2014 to March 2015,air pollution remained at low levels in Zhangjiakou,Chengde,and Qinhuangdao.AOD and PM2.5were higher in the south than in the north of the Beijing-Tianjin-Hebei region.The correlation of AOD and PM2.5showed that the nonlinear model was optimal.According to the coefficients of determination,the correlations between AOD and PM2.5were moderate in Shijiazhuang,Hengshui and Xingtai,but weak in Beijing and Tianjin.
