Abstract: Based on in-situ aerosol size-distribution measurements and Mie scattering theory, total scattering coefficients and backscattering coefficients were calculated to derived wavelength dependent lidar ratio S for 355 nm and 532 nm. Effective radius and C/F ratio of aerosol are also calculated to study the relationships between lidar ratio and particle size dependences. The results show backscatter-related scattering properties are more sensitive to coarse mode particle than total scattering. The mean values of lidar ratio for 355 nm and 532 nm are 31.9 ± 6.2 sr and 40.5 ± 6.1 sr respectively, and S₃₅₅ and S₅₃₂ are linear correlated for S₃₅₅ < 50 sr. S₃₅₅ is highly correlated with effective radius of aerosol, and S₅₃₂ is highly correlated with volume C/F ratio.
