摘要
利用云和气溶胶粒子光学特性软件包,对陆地型、海洋型和极地型三种、九类典型气溶胶粒子的散射光学特性进行了数值分析, 对比分析了每种类型不同成分对气溶胶粒子体系散射特性的影响,建立了气溶胶散射光学厚度与激光波长、相对湿度的定标关系。 对不同类型的气溶胶,气溶胶散射光学厚度随波长的幂指数衰减规律适用范围不同;成分的差异对气溶胶散射光学厚度随波长 和相对湿度的变化规律影响较大。建立的气溶胶散射光学厚度与波长、相对湿度的定标规律,可为研究非均匀气溶胶粒 子体系等效光学特性和激光工程应用提供参考和依据。
Abstract
Numerical analysis of scattering properties of three types, nine kinds of aerosols such as continental, maritime and polar type was carried out based on the software package of optical properties of aerosols and clouds. The influence of different aerosol compositions of different types on the scattering properties of aerosols was analyzed. The scaling law about scattering aerosol optical depth varies with wavelength and relative humidity is established. The power-law wavelength dependence of scattering aerosol optical depth is not satisfied at all available wavelength, and different aerosol types have differently suitable wavelength range. Aerosol composition has a great influence on the wavelength and relative humidity change law of scattering aerosol optical depth. The scaling law of scattering aerosol optical depth varies with wavelength and relative humidity can provide reference for the study of the equivalent optical properties of non-uniform aerosol particles and laser engineering applications.
