摘要提出了一个海洋水色的三分量模型，该模型考虑了浮游植物、非叶绿素颗粒和溶解有机物的贡献。该模型是基于理论上的考虑，并通过与观察到的反射光谱比较进行验证。然后，它是用来解决的问题，估计叶绿素浓度在沿海（情况2）沃茨遥感。对利用该模型模拟的大量反射光谱进行了主成分分析。结果表明，叶绿素反演的可能性，至少在某些情况下2沃茨。在沃茨中，来自少量叶绿素的信号淹没在来自大量非叶绿素颗粒和溶解有机物的噪声中，检索变得困难。非叶绿素颗粒是最容易回收的，而溶解有机物似乎是最困难的。系统的非线性限制了单一算法的可能性。
Abstract A three-component model of ocean colour is presented, that takes into account contributions of phytoplankton, non-chlorophyllous particles and dissolved organic matter. The model is based on theoretical considerations and is validated by comparison with observed reflectance spectra. It is then used to address the problem of estimating chlorophyll concentration in coastal (case 2) waters by remote sensing. Principal component analysis is carried out on a large number of reflectance spectra simulated using the model. The results indicate the possibility of chlorophyll retrieval in at least some case 2 waters. Retrieval becomes difficult in waters where the signal from small quantities of chlorophyll is drowned in the noise from large quantities of non-chlorophyllous particles and dissolved organic matter. Non-chlorophyllous particles are the most easy to recover, while dissolved organic matter appears to be the most difficult. The non-linearity of the system limits the possibility of a single algor...
