Results from these simulations show that Raman scattering strongly influences the asymptotic average cosine at wavelengths greater than about 500 nm in clear waters and 600 nm more turbid waters. At these wavelengths both the vertical behavior and the asymptotic value of the average cosine differ drastically in the presence of Raman scattering as compared to source-free waters. In red wavelengths and in clear waters, the effect of Raman scattering on the average cosine is most pronounced and a quasi-asymptotic field may be present. Our radiative transfer simulations confirm that the asymptotic diffuse attenuation coefficients at excitation and emission wavelengths are equivalent in the presence of Raman scattering. Using Gershun's equation with a source, we...
