Monte Carlo Simulations of the Sea-surface Reflectance for Above-Water Radiometric Applications Abstract:Accurate in situ measurements of water-leaving radiance Lw are needed to assess space-born radiometric products and develop ocean color inversion algorithms. Estimating Lw from above-water radiometry requires accounting for the sea-surface reflectance Rho, which is a function of the sea state, illumination conditions and measurement geometry. This work presents a preliminary investigation of the Rho dependence upon the sensor field-of-view FOV and altitude above the sea level. The analysis is conducted by modeling radiative transfer processes with the MOX Monte Carlo code and considering the AERONET-OC measurement geometry. Results indicate that the standard deviation of Rho values initially decreases when the sensor height h_s from the sea level increases, and then becomes constant above the height h_s^* where the sensor can properly capture the entire range of sea-surface reflectance variability. The h_s^* dependence on the sensor FOV and sun position is also documented.
