Abstract The aerosol scattering proterties in the hinterland of Taklimakan Desert was continuously observed by integrating Nephelometer in 2004, which in combining with the data of mass concentration of PM10, the visibility and the routine weather observation,the seasonal and daily variation features of aerosol scattering coefficients and its correlation with the PM10 and the visibility were analyzed. The results indicate that the hourly mean aerosol scattering coefficient, the mean mass concentration of PM10,and the mean visibility at TaZhong in 2004 were 124.74±187.30 Mm-1, 538.9±841.7 μg·m-3,and 12 748±7 274 m, respectively. The maximum frequency distribution of the hourly mean scattering coefficient is below 100 Mm-1, and the aerosol scattering coefficient is higher in the morning and evening,while it is lower at noon during a day. There are more particles in the air in the wee hours in winter and spring,so the aerosol scattering coefficients are more higher; The variations of the hourly mean aerosol scattering coefficient and the mass concentration of PM10 are consistent. The daily mean aerosol scattering coefficients and the visibility are significantly correlated,and their relationship might be described by a negative power function.
