Abstract

The inversion of aerosol optical depth (AOD) of Beijing in each four seasons of 2014 year was carried out in this paper. The results show that, in seasonal distribution, the AOD of Beijing city was lower in winter and spring, stable in summer and autumn. In spatial distribution, the AOD is large in the centre area and the southwest area of Beijing city and small in the suburbs of Beijing city, because there’s less air pollution. Further exploration of correlation between AOD and PM2.5, R2, the squared value of the correlation coefficient of them (R) is 0.03 in spring, 0.74 in summer, 0.45 in fall, 0.44 in winter. It can be seen that the correlation of PM2.5 and AOD was higher in summer, lower in spring, and the correlation in fall was similar with it in winter.
