Abstract : Results of Monte Carlo simulation of light fields in an absorbing and scattering ocean with all fifteen Petzold phase functions and 37 sun elevation angles between 0 and 90 degrees are presented. The computed values of diffuse reflectance for all 15 phase functions are regressed with the sun elevation. The simulations cover the range for phase functions eccentricity factor between 5 and 120 the range of single-scattering albedo between 0.09 to 0.96. The results of the computation show the importance of the phase function and the sun elevation angle in determining diffuse reflectance. The approach shows how new computational abilities improve the probability of realistically modeling radiative transfer over a wide range of conditions.
