摘要
BRDF是湖泊水体光学特性研究与辐射传输仿真研究的重要模型,该文通过对常用海洋方向辐射仿真模型在内陆湖泊的应用,对中国太湖这一典型浑浊内陆湖泊进行适用性分析。根据太湖自然地理特征,将太湖划分为7个湖湾区域。根据5个半经验BRDF模型(MAG2002、Lee2004、Park-Ruddick2005、Woerd-Pasterkamp2008和Lee2011)计算方向辐射仿真结果,与多角度MISR卫星遥感数据大气校正后的方向辐射进行定量拟合比较。综合结果表明,Woerd-Pasterkamp2008和Lee2011具有最好的拟合效果,是内陆湖泊适用性最好的模型。
BRDF is an important model for the research of optical characteristics and radiation transfer simulation of lake water bodies.This paper analyzes the applicability of Taihu Lake,a typical turbid inland lake in China,by applying common ocean directional radiation simulation models to inland lakes.Based on the natural geographical characteristics of Taihu Lake,Taihu Lake is divided into 7 bay areas.The directional radiation simulation results were calculated based on five semi-empirical BRDF models(MAG2002,Lee2004,Park-Ruddick 2005,Woerd-Pasterkamp2008,and Lee2011),and were quantitatively fitted and compared with the directional radiation after atmospheric correction of multi-angle MISR satellite remote sensing data.The comprehensive results show that Woerd-Pasterkamp2008 and Lee2011 have the best fitting results and are the best applicable models for inland lakes.
