Paper Abstract

This paper aims at developing a method to use satellite retrievals aerosol optical thickness (AOT) and filed measured AOT to monitor air particulate pollution. This work is applied during the entire year of 2009, on Wuhan area, central China. The ground level daily mean PM10 mass concentration is measured by tapered element oscillating microbalance. Meanwhile, local daily mean AOT is obtained by using field spectrometer. After that, the correlations between local daily mean AOT and PM10 concentrations are calculated. As the AOT MODIS retrieval AOT has good agreement with field measured ones, the good correlation between MODIS AOT and PM10 mass concentration is demonstrated, and the correlation coefficients range from 0.67 to 0.77. This correlation coefficient has strong season dependence which indicates that the correlation in spring and summer is high, while it is much lower in winter. Then the correlation is improved according to the impact of relative humidity. Based on the good correlation condition, the linear regression analysis is completed with the help of SPSS Statistics.
