Ocean BRDF measurement and effects

With NASA support, starting in the era of MODIS Terra, we developed a new instrument to measure the upwelling radiance distribution at the surface (NuRADS). The aim of this instrument was to determine the variation in the upwelling radiance, right below the surface. The application was for validating models of this angular variation of the upwelling lightfield. While we are still continuing this effort, many papers have already been written on this effort. A list of the papers to date are shown below:
