摘要	This paper presents a method to obtain aerosol-lidar ratio and particle-size distribution simultaneously with a dual-wavelength lidar, when the aerosol particle-size distribution is to be approximated by a Junge distribution. The manuscript analyzed the relationship between the aerosol particle ratio, particle-size distribution, and particle complex refractive index. The results show that the particle properties have a great impact on the lidar ratio. If the selected lidar ratio is not suitable, the extinction coefficient obtained from the Fernald method will cause a great uncertainty in the inversion of particle-size distribution. A lidar-ratio iteration method was introduced to solve the influence of improper lidar-ratio selection on particle-size distribution inversion, and then conducted simulation calculations and analysis. The simulation results show that the lidar-ratio iteration method effectively solves the problem of uncomfortable lidar ratio, and can obtain relatively accurate lidar ratio and particle-size distribution parameters at the same time; the uncertainty of iteration method was discussed in the manuscript.
