The RAdCor project aims to develop a tool for a spatially explicit compensation for the diffuse transmittance of the atmosphere, taking into account the spatial contrast of surface reflectance. This would enable atmospheric compensation codes based on the Dark Spectrum Fitting, such as ACOLITE, to compensate for what is known as "Adjacency Effect". Such a tool is fundamental to be able to apply remote sensing tools for water quality in near shore environments (< 1km from shore), which for small lakes and rivers usually represent the totality of their surface area. The RAdCor project will use physically based methods to model the spatially explicit atmospheric transmittance, enabling application at generic sensor altitudes, view angles and wavelengths. The project also intends to use sophisticated mathematical and computational tools to increase the compensation processing speed, a typical bottleneck for operational application of adjacency effect compensation. The project is lead by Quinten Vanhellemont of the Royal Belgium Institute of Natural Sciences, in partnership with Koen Sabbe from the Protistology and Aquatic Ecology  research group of Ghent University.
