Short summary

Retrievals of surface solar radiation from passive satellite instruments normally neglect the three-dimensional (3D) interaction between clouds and radiation. This study identifies error sources arising from this neglect and demonstrates their influence on retrieval accuracy across a range of spatial resolutions. At the resolution of current geostationary satellites, 3D interactions can already introduce considerable errors, underscoring the need to develop corrections that account for them.
