Remote sensing of ocean color, applied to the estimation of chlorophyll biomass, is discussed for the case where the vertical distribution of phytoplankton pigments is nonuniform. Using a spectral model of reflectance, the consequences of vertical structure are evaluated by sensitivity analysis on a generalized pigment profile. It is shown that the assumption of a vertically homogeneous chlorophyll distribution can lead to significant errors (relative error exceeding 100%) in the estimation from satellite data of photic depth and total pigment content in the photic zone. The errors are shown to be functions of the parameters of the pigment profile. It is further shown that, if the shape of the pigment profile is known from independent data, the entire pigment profile may be recovered from the satellite data by making slight changes in the existing algorithms for chlorophyll retrieval.
针对浮游植物色素垂直分布不均匀的情况，讨论了应用海洋颜色遥感估算叶绿素生物量的问题。利用反射光谱模型，通过对广义色素剖面的敏感性分析来评估垂直结构的影响。结果表明，假设叶绿素垂直分布均匀会导致从卫星数据估算光合深度和光合层总色素含量时出现显著误差（相对误差超过100%）。这些误差是色素剖面参数的函数。进一步表明，如果从独立数据中已知色素剖面的形状，那么通过对现有的叶绿素反演算法进行微小修改，就可以从卫星数据中恢复整个色素剖面。
