摘　　要：通过对PM10浓度与MODIS气溶胶光学厚度进行相关分析,结合湿度订正和垂直订正建立了MODIS气溶胶光学厚度与地面PM10浓度的回归模型,并用该模型对杭州的PM10浓度进行了反演。反演结果与PM10的实测值吻合性较好,拟合系数(R2)为0.660,平均误差为0.028。PM10mass concentration retrieval using satellite remote sensing data is complementary to ground based PM10 monitoring,which is difficult to get the regional distribution pattern because of limited monitoring stations.In this paper,the correlation of PM10 mass concentrations and MODIS aerosol optical depth(AOD)is analyzed.After the humidity correction and vertical correction for MODIS AOD,a retrieval model of PM10mass concentration using AOD is established.The experiment in Hangzhou city indicates a good correlationship between the estimated and ground truth values(fitting coefficients R2=0.660),and the mean error of this model is 0.028.
