TL;DR: The ratio of rho(path) to the Rayleigh reflectance for an aerosol-free atmosphere is linearly related to the aerosol optical thickness, which provides a basis for a new scheme for atmospheric correction of remotely sensed ocean color observations.
Abstract: Single and multiple scattering by molecules or by atmospheric
aerosols only (homogeneous scattering), and heterogeneous
scattering by aerosols and molecules, are recorded in Monte Carlo
simulations. It is shown that heterogeneous scattering (1)
always contributes significantly to the path reflectance
(ρpath), (2) is realized at the expense of
homogeneous scattering, (3) decreases when aerosols are absorbing,
and (4) introduces deviations in the spectral dependencies of
reflectances compared with the Rayleigh exponent and the aerosol
angstrom exponent. The ratio of ρpath to the Rayleigh
reflectance for an aerosol-free atmosphere is linearly related to the
aerosol optical thickness. This result provides a basis for a new
scheme for atmospheric correction of remotely sensed ocean color
observations.
