| Abstract |
The water-leaving radiance measurement is a key element in the validation of atmospheric corrections over ocean. The latter requires the correction for the Fresnel reflection of the sky dome by the water surface. Currently, this correction is achieved with a measurement of of the sky radiance and the use of a Fresnel reflection coefficient, ignoring the polarization processes. Our objective is to illustrate the bias induced by neglecting the polarization in the reflected sky dome by the sea surface. Results from this study clearly stress that the polarization has to be accounted for. |
