A vector radiative transfer model has been developed for coupled atmosphere and ocean systems based on the Successive Order of Scattering (SOS) Method. The emphasis of this study is to make the model easy-to-use and computationally efficient. This model provides the full Stokes vector at arbitrary locations which can be conveniently specified by users. The model is capable of tracking and labeling different sources of the photons that are measured, e.g. water leaving radiances and reflected sky lights. This model also has the capability to separate florescence from multi-scattered sunlight. The delta - fit technique has been adopted to reduce computational time associated with the strongly forward-peaked scattering phase matrices. The exponential - linear approximation has been used to reduce the number of discretized vertical layers while maintaining the accuracy. This model is developed to serve the remote sensing community in harvesting physical parameters from multi-platform, multi-sensor measurements that target different components of the atmosphere-oceanic system.
基于逐次散射阶数（SOS）方法，开发了一种用于大气和海洋耦合系统的矢量辐射传输模型。本研究的重点是使该模型易于使用且计算高效。该模型可在用户方便指定的任意位置提供完整的斯托克斯矢量。该模型能够跟踪和标记所测量光子的不同来源，例如离水辐射率和反射天光。该模型还具有从多次散射的太阳光中分离荧光的能力。采用了δ拟合技术来减少与强烈前向峰值散射相位矩阵相关的计算时间。使用指数 - 线性近似来减少离散垂直层数，同时保持精度。开发该模型是为了服务于遥感界，以便从针对大气 - 海洋系统不同组成部分的多平台、多传感器测量中获取物理参数。
