基于VLIDORT矢量辐射传输模型,应用灰霾型气溶胶的物理参量,计算了不同条件下的灰霾气溶胶偏振辐射特性,并与常用气溶胶模式下计算的偏振辐射进 行分析对比,得到了灰霾气溶胶条件下偏振辐射对于几何位置、气溶胶光学厚度、气溶胶复折射指数、单次反照率、地表参数的敏感性。对于利用偏振 辐射实现灰霾气溶胶监测以及气溶胶复折射指数与光学厚度反演提供了理论依据。
Abstract
Based on the vector radiative transfer model-VLIDORT, the polarization characteristics of haze by using haze optical properties under different conditions are calculated. On the analysis and comparison of polarization characteristics under the common aerosol models and haze aerosol, the sensitive of geometry, aerosol optical thickness, aerosol complex refractive index, single scattering albedo and surface parameters are obtained. Theoretical references for haze aerosol monitoring, retrieving aerosol optical depth and aerosol complex refractive index by using polarized radiation are provided.
