【 摘 要 】

The correlation between MODIS aerosol optical thickness AOT and PM2.5 concentration in Fuling District of Chongqing was studied. The results showed that AOT and PM2.5 had significant seasonal variation characteristics, and the daily mean correlation Which was significant in the summer and poor correlation in winter. The influencing factors affecting the correlation between MODIS AOT and PM2.5 were studied, and the correlation coefficient between them was also greatly improved. Therefore, it is of great value to use MODIS AOT to monitor the distribution of PM2.5 in atmospheric particulate pollutants.
