Fig. 5: (Top) Relative contribution to the top-of-atmosphere total reflectance of 
photons that have interacted with the water body; (Bottom) Same as (Top), but 
unpolarized reflectance. Atmospheric and oceanic conditions and sun geometry are 
those of Fig. 3. For some viewing geometries, outside the glitter region in forward 
scattering, the signal originating from the water body represents as much as 45% of 
the top-of-atmosphere unpolarized reflectance.
