| 摘 要： | 黄色物质和非色素颗粒物是我国近岸水体重要的水色成分，对其光谱特性的了解，直接关系到水色遥感色素算法的精度。文章对2003春季黄东海航次获取的数据分析处理，得到黄色物质吸收系数斜率经验值Sg=0.0175和非色素颗粒物吸收系数斜率经验值Sd=0.0103。经采用2002春季和2003秋季同海区试验数据进行检验，结果表明得到的光谱模型具有较强的区域适用性。

| Abstract: | The yellow substance and the de-pigment particles are main components of ocean colors in Chinese coastal waters Understanding of their spectral character is related to the accuracy of the ocean color pigment algorithm In this paper, we analyze the data set collected in 2003 Spring Cruise of Yellow Sea and East China Sea, and get the spectral slope of yellow substance( S g =0 0175) and that of de-pigment particles( S d =0 0103) The verified results, which are tested with the data set of the same zone in 2002 Spring Cruise and 2003 Autumn Cruise, show that this spectral mode is strongly suitable for this region |
