Monte Carlo computations of the diffuse reflectance of an ocean consisting of two homogeneous layers with differing optical properties are presented, along with a simplified method of computation that uses results of previous Monte Carlo simulations. It is demonstrated that it is impossible to distinguish between thin layers of strong scattering and thick layers of weak scattering through measurement of the diffuse reflectance. Analyzing the two-layer reflectance under the assumption of a homogeneous ocean yields an optical property that is shown to be nearly the average of the associated property over the penetration depth of the medium, i.e., the depth over which the downwelling irradiance falls to l/e of its value at the surface.
本文给出了由两个具有不同光学特性的均匀层组成的海洋漫反射率的蒙特卡罗计算结果，以及一种使用先前蒙特卡罗模拟结果的简化计算方法。结果表明，通过测量漫反射率无法区分强散射薄层和弱散射厚层。在均匀海洋假设下分析双层反射率，得到一种光学特性，该特性显示几乎是介质穿透深度（即下行辐照度降至其表面值的1/e时的深度）上相关特性的平均值。
