Estimation of upward radiances and reflectances at the surface of the sea from above-surface measurements

Ø. Kleiv, A. Folkestad, J. Høkedal, K. Sørensen, and E. Aas

Ocean Sci., 11, 779–788, https://doi.org/10.5194/os-11-779-2015,https://doi.org/10.5194/os-11-779-2015, 2015

Short summary

A method which determines the radiance reflectance at the surface as well as the water-leaving and reflected radiances solely from the measurements of upward nadir radiance and downward irradiance in air is presented. A comparison between this method and in situ measurements shows that the average relative deviations between their results are less than or equal to 15% for the reflected radiance, at the studied wavelengths.
