用Mie散射理论计算大气气溶胶光学特性

Using the MIE theory to calculate aerosol optical characterization

本文在已知厦门海域气溶胶粒子谱分布的基础上,用MIE散射理论计算了该地区气溶胶粒子的光学特性,得到了气溶胶粒子的散射截面、吸收截面、消光截面与波长的关系,散射相函数以及偏振相函数,并用实验对两个相函数加以了验证。此结论为研究大气矢量辐射传输提供了很好的方法;尤其偏振相函数的提出为今后用偏振的方法研究大气提供了理论依据。

Base on the aerosol size distribution function, we have reported the aerosol optical characterization, such as scattering, Extinction, Absorption efficiency and coefficient, scattering and polar phase function over XiaMen＇s sea by using the Mie theory in this paper. These results provide excellence method to resolve the vector RTE. The polar phase function provides the theories basis in order to research atmosphere by using the polarization of method in the future.
