“…where f /Q is a factor dependent on the Sun, the viewing geometry, and the volume scattering function of water. a t (λ) is the total absorption coefficient of all the material components in the water, as relation (4), where a w (λ), a ph (λ), a NAP (λ), and a CDOM (λ) are the absorption coefficients for pure water, phytoplankton, NAP, and colored dissolved organic matter (CDOM), respectively. b bt (λ) is the total backscattering coefficient that is composed of b bw (λ), b b,ph (λ), and b b,NAP (λ), which correspond with the above water components, as relation (5).…”
