Keyword:  漫衰减系数遥感反射比东中国海经验算法;
Abstract: 东中国海是典型的二类水体或者浑浊水体,海色传感器SeaWiFS和MODIS漫衰减系数Kd(490)的业务化反演算法—Mueller算法在东中国海不再适用。基于2006—2007年3个东中国海航次的现场数据和模拟数据基础上提出了一种漫衰减系数Kd(490)的反演算法,在Mueller算法基础上增加了620 nm的波段信息以反映东中国海浑浊水体的特性。该算法与3个航次的东中国海现场数据进行印证,反演相对误差为12.1%,均方根误差0.08,相关系数0.99(N=74)。结果表明该算法有效提高Mueller算法在东中国海的反演精度。
