摘　　要：运用AERONET观测资料对MODIS MCD19A2、葵花8AOD产品进行验证,结合ERA5资料分别对两卫星平台的AOD、PM2.5浓度进行订正并分析两者相关性,结果表明:MCD19A2相较葵花8 AOD数据质量更贴近地基观测值,未经订正的AOD-PM2.5相关系数较低,在垂直-湿度订正后,在α=0.01置信水平下显著相关,两平台相关系数分别为由0.36、0.4提升至0.69、0.58。The MODIS MCD19A2 and Himawari-8 AOD products are verified by AERONET observations,and the AOD and PM2.5 concentrations of the two satellite platforms are corrected by combining ERA5 data and the correlations between the two are analyzed.The results show that,MCD19A2 is closer to the ground-based observations compared with Himawari-8 AOD data quality,and the correlation coefficient of AOD-PM2.5 without correction is lower,and after verticalhumidity correction,there is a significant correlation at the confidence level ofα=0.01.The correlation coefficients of the two platforms increase from 0.36 and 0.4 to 0.69 and 0.58,respectively.
