Investigation is performed of the space/time features of MODIS data retrieved aerosol optical thickness in the east and middle of China in 2001 and MM5 simulation is conducted of the forcing of sulphate aerosol on direct radiation and its climate effect.

• 分析了MODIS卫星资料反演的2001年我国中东部地区气溶胶光学厚度的时空分布特征,并利用中尺度数值模式MM5对该地区硫酸盐气溶胶的直接辐射强迫及其气候效应进行了模拟。
