Based on HYDROLIGHT simulations of more than 2000 reflectance spectra from datasets typical of coastal waters with highly variable optically active constituents as well as on intercomparisons with field measurements, the magnitude of chlorophyll fluorescence was analyzed and parameterized as a function of phytoplankton, CDOM, and suspended inorganic matter concentrations. Using the parameterizations developed, we show that variations in the fluorescence component of water leaving radiance in coastal waters are due more to the variability of attenuation in the water than to the variability of the fluorescence quantum yield, which we estimate to be relatively stable at around 1%. Finally, the ranges of water conditions where fluorescence plays a significant role in the reflectance NIR peak and where it is effectively undetectable are also determined.
基于对来自具有高度可变光学活性成分的典型沿海水域数据集的2000多个反射光谱的HYDROLIGHT模拟，以及与实地测量的相互比较，分析了叶绿素荧光的大小，并将其参数化为浮游植物、有色溶解有机物（CDOM）和悬浮无机物质浓度的函数。利用所开发的参数化方法，我们表明，沿海水域离水辐射亮度的荧光成分变化更多是由于水中衰减的变化，而不是荧光量子产率的变化，我们估计荧光量子产率相对稳定，约为1%。最后，还确定了荧光在反射近红外峰值中起重要作用以及有效不可检测的水条件范围。
