| 摘 要： | 基于POLDER多角度观测数据,对其大气校正算法进行了研究。该大气校正算法中,大气分子散射利用多次散射加偏振的精确瑞利散射来计算,同时,对太阳耀斑及白帽散射进行了校正。由本文大气校正算法可以反演得到气溶胶光学厚度以及海水反射率,与POLDER二级产品相比表明,利用该算法反演所得产品效果较好,相对误差在10%左右,从而为未来中国多角度水色遥感的发展提供一些参考。 |

| Abstract: | Using the multi angle observation data of POLDER,the ocean color atmospheric correction algorithm is studied. In this algorithm,scattering by air molecule is computed by exact Rayleigh scattering,the foam scattering and sun glint are also corrected. Using the atmospheric correction algorithm described in this paper,the aerosol optical thickness and marine reflectance are obtained and compared with the POLDER level-2 product. The comparison indicates that ocean color product retrieved by this algorithm is go... |
