摘要
该文系统地研究了ＢＲＤＦ反演和大气纠正的关系。研究中用到了ＭＯＤＩＳ的大气纠正法，而且，对于不同的植被类型和气溶胶光学深度用到了ＭＯＤＩＳ和ＭＩＳＲ的角度采样。结果显示在大气纠正中考虑ＢＲＤＦ表面各向异性是必要的，而且表面ＢＲＤＦ的反演和大气纠正可以迭代进行，大量模拟证明这一迭代收敛迅速。
This paper systematically studies the relationship between surface BRDF (Bidirectional Reflectance Distribution Function) retrieval and atmospheric correction. The study uses the atmospheric correction scheme of the Moderate Resolution Imaging Spectroradiometer (MODIS), and angular sampling expected for MODIS and MISR (Multiangle Imaging SpectroRadiometer) for different land cover types and optical depths of aerosols. The results show that it is necessary to consider the surface anisotropic BRDF in atmospheric correction, and surface BRDF retrieval and atmospheric correction can be coupled in a converging iteration loop.
