基于气溶胶光学厚度反演大气气溶胶尺度分布

Retrieving of aerosol size distribution based on the measurement of aerosol optical depth

介绍一种基于气溶胶光学厚度测量反演大气气溶胶尺度分布的新方法.从实测气溶胶光学厚度出发,依据严格的Mie散射理论,将气溶胶尺度分布函数离散,采用线性回归法确定气溶胶尺度分布.还通过对多重共线性的讨论,确定了用于反演气溶胶尺度分布的光谱波段.

A new method for retrieving aerosol size distribution from measurement of aerosol optical depth is reported. Depending on the rigorous Mie scattering theory and the measured optical depth, dispersing the aerosol size distribution, by using linear- regression method, the aerosol size distribution can be calculated directly. And also the suitable wavelength band to retrieve the aerosol size distribution is obtained by analyzing the multi -collinearity.
