简介:河口的分布给溶解有机物(CDOM)涂颜色是physicalbiogeochemical过程的联合结果。遥感动态地高度被需要到监视器河口CDOM。从四季节的巡航在situ数据使用,一个算法被开发在400nm估计CDOM吸收系数(在Zhujiang(珀尔河)的CDOM(400))河口(ZJE)。Rrs(667)/Rrs(443)和Rrs(748)/Rrs(412)。由使用它在水上节制分辨率成像分光辐射函数从2002~2014的卫星(MODIS/Aqua)数据,季节的气候学在ZJE的CDOM(400)被计算。CDOM分布主要地走水路被影响来自Zhujiang河的分泌物并且在水下地形学。沿着对一个水深度坡度垂直的节,季节CDOM(400)指数地减少了(y=aebx,b<0),但是与在季节之中的大差别。河流的新鲜的水是在ZJE的CDOM的主要来源。有增加咸度的Fulvic酸部分减少。用发达算法,保守CDOM混合方程,和河分泌物,在从2002~2014的夏天和冬季的溶解的器官的碳(文档)的有效河流的结束成员集中和流动首先从MODIS/Aqua数据被估计。两有效河流的结束成员文档集中和流动是断然与河有关排出,显著地在有为集中的0.698的R2的夏天并且0.9657为流动。
