英文摘要

Lidar ratios and Angstrom exponents of continental, maritime, and desert aerosols were calculated to evaluate the effects of aerosol composition on these parameters. Their correlation was assessed using correlation analysis and curve fitting. The Pearson correlation coefficient between the lidar ratio and the Angstrom exponent was larger than 0.95 in all cases. We verified the reliability of the Pearson correlation coefficient using the significance test. The relationship between the lidar ratio and the Angstrom exponent of continental aerosol can be described by a cubic polynomial model; thus, the function relation between the change in lidar ratios at different laser wavelengths depends on the fitting coefficients and the Angstrom exponent. The relationship between the lidar ratio and the Angstrom exponent of both maritime and desert aerosols can be described by a linear model. In these aerosols, the linear change in lidar ratios at different laser wavelengths remains unaffected by the Angstrom exponent. The changes in the lidar ratio in maritime aerosol at 355 nm and 532 nm are -0.7 times and -0.18 times that at 1064 nm, respectively. For desert aerosol, the changes in the lidar ratio at 355 nm and 532 nm are 0.37 times and 1.88 times that at 1064 nm, respectively.
