摘    要:卫星对地观测定量遥感地表与大气特性是当前地球科学与应用研究的关键手段之一。在定量遥感中区分大气和地表在地-气系统对空间散射辐射中各自的贡献与作用是关键的一步。这一问题的核心是基于辐射传输方程的数值计算建立起适合应用于遥感反演中分离大气与地表贡献的参数化表达式。本文对特定的气溶胶气候类型和可见/近红外波段建立起定量的表达形式,并对表达式的物理含义和拟合精度进行了分析。最后讨论了其应用的可行性和进一步的工作。

关 键 词:辐射传输    大气订正    大气气溶胶    光学遥感    辐射参数化    卫星遥感反演

Abstract:Quantitative remote sensing of the earth surface and the atmosphere is one of the key means for current and future earth science and application research To separate the respective contributions to satellite observed radiance by the earth surface and the atmosphere is the key step for quantitative retrieval of earth and atmosphere parameters To solve this problem, it is feasible to establish the parameterized expression based on radiative transfer computation This kind of parameterized expression can be easily applied to the remote sensing retrieval In this paper we established such expression in visible and near infrared wave band for certain atmospheric conditions The physical interpretation and the fitting accuracy are discussed Finally, the strategy for application and further works are summarized
Keywords:radiative transfer  atmospheric correction  atmospheric aerosols  optical remote sensing  radiative parameterization  retrieval of satellite remote sensing
