A Raman lidar has been developed with photon counting technique. Aerosol and cloud extinction coefficients are derived by nitrogen (N 2) molecular Raman scatter returns in the troposphere. Both backscatter coefficients and extinction-backscatter-ratios of aerosol and cloud are presented by simultaneously combining N 2 Raman and Mie-Rayleigh returns of aerosol and molecule. Ratios of extinction to backscatter between 20 sr and 70 sr are usually found for aerosol, but less than 15 sr for mid-high altitude cloud in the troposphere.

A new method is proposed based on the analysis of lidar equation which selects aerosol backscatter ratio at a reference point for short range lidar in data processing. Simulation computation and experimental comparison results show that this method is reasonable and feasible. The method is applied to short range lidars, such as atmospheric monitoring lidar-2 （AML-2） and micro-pulse lidar （MPL）.

根据米氏(Mie)散射理论,通过数值模拟分析了气溶胶折射率虚部n_i在不同散射角度上对双散射角激光光学粒子计数器(L-OPC)响应曲线的影响,定义了敏感函数。根据分析,散射角应该在小于20°和40°～60°之间选取。以散射角系统ψ=9°,β=5°,λ=0．65μm和ψ=50°,β=20°,λ=0．65μm为例,其中一个散射角受折射率虚部n_i的影响较小,另一个较大。在测量粒子谱分布的同时,利用n_i对不同散射角度响应曲线的影响差异,来确定n_i值,并提出确定n_i的方法。还给出了双散射角激光光学粒子计数器的模拟测量结果。
