Paper Abstract

This paper describes an analytical 2 flow equations solution and compares it to a Monte Caro model of the photon flux in water. Both models are designed to generate synthetic water surface reflectance signatures as well as the vertical profiles of light in a homogeneous or non-homogeneous water column of specified depth and bottom reflectance. In this paper we compare and contrast the results of the models and develop a theoretically based attenuation function of both models. The results from the Monte Carlo model are used to compare a form of a 2nd order attenuation term (Psi) , resulting from a solution of the 2-flow equation, to 3 downwelling irradiance dependent terms. The results show that (Psi) differs from the three terms by 1 to 14 percent depending on the scattering to absorption ratio and volume scattering function. The result also show that (Psi) is dependent on the shape factor.
