AB: An impulse response solution (Green matrix) is developed to solve the vector radiative transfer equation (VRTE) in a 3D atmosphere-ocean system (AOS). The system is divided into three parts: the atmosphere, the dielectric interface, and the ocean. For the atmosphere and ocean, the impulse response functions are calculated by the Monte Carlo method. For the dielectric interface, the impulse response function is calculated by the Fresnel formulas. The matrix operator method is then used to couple these impulse response functions to obtain the vector radiation field for the AOS. The primary advantage of this hybrid method is that it solves the VRTE efficiently in an AOS with a time dependent dielectric interfaces but with the same atmospheric and oceanic conditions. We present the downward radiance field in an ocean with a real time dependent sinusoidal ocean wave.
