摘要
以海洋水色因子(悬浮泥沙、叶绿素、黄色物质)浓度的大量实测资料为主要输入,对水体光谱反射率进行模拟(正演),进而分析黄色物质浓度与模拟光谱资料的关系,确定提取黄色物质浓度信息的最佳波段组合,并以此波段组合建立黄色物质浓度信息提取模式(反演)。对模拟光谱资料与卫星遥感光谱资料的关系进行了推导,将反演模式应用于卫星遥感资料,并利用SeaWiFS资料提取珠江口水域黄色物质浓度信息,初步实现了海水黄色物质浓度的卫星遥感信息提取。
A threecomponents ocean color model was used for simulation of water reflectance by inputting water components data measured in the Zhujiang River estuary of southern China. Based on the simulated reflectance data and measured yellow substance data, an optimum band combination was found and alocal algorithm for estimation of yellow substance concentration was developed. Then the algorithm was applied to SeaWiFS data for retrieval of yellow substance. The application results showedthat the estimated yellow substance is in closeagreement with the insitudata in terms of concentration and distribution pattern.
