A radiation station was installed on drifting sea-ice in the Arctic Ocean during the MOSAiC expedition between November 2019 and September 2020. The station measured all the components of the surface radiation budget, that is the broadband downwelling and upwelling shortwave and longwave irradiance, as well as the downward direct and diffuse partitioning of downwelling irradiance. The dataset contains the raw data and the calibrated radiative fluxes recorded at two second temporal resolution for the entire annual cycle of the MOSAiC expedition. The data are not quality checked and occasionally suffer from frost accumulation on the domes of the sensors. Breaks in the dataset occur when the station was removed from the sea-ice, before the research vessel Polarstern temporarily left the ice floe in May 2020 and before the disintegration of the original ice floe in July 2020. The station was installed at the Central Observatory (CO1, CO2, CO3) of MOSAiC on first-year sea-ice: from 12th of November 2019 to 10th ...
