The upwelling spectral radiance at the ocean surface, as influenced by four different ocean floor spectral reflectances. The water column depth is 5 meters. The water column effectively removes light from the upwelling signal at wavelengths longer than 600 nm, and greatly attenuates the upwelling signal at wavelengths shorter than 400 nm. The upwelling spectral radiance at the top of the atmosphere, as influenced by four different ocean floor spectral reflectances. The water column depth is 5 meters. Rayleigh scattering by the atmosphere increases the radiance at the shorter wavelengths, but does not detract from our ability to discriminate between scenes. |
