Abstract Microtops II sun photometers were used to retrieve data on the aerosol optical depth (AOD550) and Angström wavelength exponent (α) over Ebinur Lake region in spring. The results showed that high frequency value of AOD mainly concentrated in 0.1~0.4Affected by diffusion and sedimentation of salt dust, there were some differences in the aerosol optical properties between Jinghe and Wusu region. The mean values of AOD in Jinghe and Wusu were 0.290 and 0.242 with coefficients of variation were 62.966%, 47.444%, the mean values of α were 0.609 and 0.894 with coefficients of variation were 33.368% and 56.946%, it showed that atmospheric aerosol particle size was relatively large in Jinghe and the particle size of aerosol particles changed significantly in Wusu region; It had a complex relationship between AOD and α; the local dominant wind was the leading factor of dust aerosols. Temperature not played a critical role in the local changes of AOD. When α <0.5, AOD and RH showed a negative correlation in Wusu, while Jinghe area showed a hygroscopic due to the impact of soluble ions in salt dust. When α>1.0, the hygroscopic growth of fine particles lead to AOD and RH showed a positive correlation trend, When 0.5 < α < 1.0, aerosol showed a certain hygroscopic, while when RH>50%, it was not surprising that rainfall lead to reduced aerosol concentration. The results showed that the high AOD in Jinghe mainly caused by the dust aerosols and the high AOD in Wusu both clustering in the fine mode growth wing and the coarse mode.
