摘要
气溶胶光学厚度不仅是计算气溶胶含量、评价大气环境污染程度、研究大气辐射传输等领域中的一个关键 因子,而且在大气辐射传输方程的求解过程中,是透射函数、反射函数等重要参数的基本 参数。通过分析气溶胶光学厚度的影响因子,搜集整理典型天气气溶胶粒子复折射率资料和粒子谱 分布观测数据,建立典型天气气溶胶粒子复折射率数据库,基于气溶胶粒子谱分布实验数据完善了大 连地区典型天气气溶胶粒子谱分布模型,再结合大气能见度等大气参数,利用米散射理论计算了气溶胶 消光光学厚度。
Abstract
Optical depth is a key factor for the study of aerosol content calculation, the degree of atmospheric pollution and atmospheric radiative transfer. Transmission function, reflection function, single scattering albedo and other important physical parameters of atmospheric transmission are functions of the optical depth. The database of complex refractive index in typical days is established, and aerosol particle size distribution model is improved based on experimental data. Considering atmospheric visibility and other atmospheric parameters in Dalian, the aerosol optical depth is calculated based on the Mie scattering theory.
