摘要

气溶胶散射特性对大气辐射和气候研究具有重要意义。为研究气溶胶在不同相对湿度下的散射特性

根据Mie散射理论建立了湿度偏振模型

在0.55 m的可见光下

分析比较了3种气溶胶的单粒子和粒子群在不同相对湿度下的偏振特性。结果表明

相对湿度变化对气溶胶偏振度有规律性的影响

尤其在120~150的后向散射角区域

3种粒子偏振度都随相对湿度的增大而增大

说明了部分后向散射角上散射光偏振度能有效反映气溶胶粒子随相对湿度变化的信息。

Abstract

Aerosol scattering characteristic is very important for atmospheric radiation and climate research. In order to study the aerosol particles scattering properties in different relative humidity

we firstly got the humidity polarization model based on the Mie scattering theory

then compared and analyzed the polarization properties of single particle and particle cluster of three aerosols in different humidity conditions. The results show that relative humidity have regularity impact on the polarization properties of aerosol particles

especially in the area between 120 to 150. It means that the scattering light polarization degree of some backward scattering angel can effectively reflect the relative humidity's change of aerosol particles.
