大气污染与平流层气溶胶

Atmospheric Pollution and Stratospheric Aerosols

本文简述了大气污染与气溶胶的关系,论述了平流层气溶胶对地球辐射收支的影响,从而说明平流层气溶胶的光学性质的变化将影响全球大气环境,在此基础上,计算了不同背景平流层气溶胶的光学常数和光学特性参数。并使用模式光学常数计算了3种火山模工气溶胶的光学特性参数。同时,考察了这些特性参数对光学常数的敏感性。结果表明,后向散射系数(或后向散射截面)对光学常数的变化最敏感,对于某些波长,它的相对变化可比光学常数的相对变变大一个数量级。

The relationship between atmospheric pollution and aerosols and the impact of stratospheric aerosols on the incomig and outgoing radiation of the earth are elucidated. Based on the explanation of the impact of the changes of optical property of aerosols on the global atmospheric environment, optical constants and parameters of different background stratospheric aerosols are computed. And the optical parameters of three kinds of volcanic aerosol are computed by applying model optical constants.
