%X Shanghai is one of the important coastal city in East Asia,the study of atmosphere aerosol optical characteristics over this region is important for understanding the environment and the climate simulation in Shanghai and East China.This work used the observation data of the direct solar irradiance from June 2000 to December 2002 to obtain the aerosol optical depths(AOD).Then we analyzed the statistical characteristics of AOD,such as seasonal variation,correlation with surface visibility,etc.At last,we drew the spectral distribution of AOD.The results show that the AOD in Shanghai is largest in summer,then less in spring,and smallest in winter.In addition,the surface visibility and its reciprocal has nice correlation with the AOD,it can be used as a parameter to restrict the AOD distribution.
