Longwave and shortwave radiative energy budget components derived from broadband irradiance observations during the Airborne measurements of radiative and turbulent FLUXes of energy and momentum in the Arctic boundary layer (AFLUX) campaign north of Svalbard in March / April 2019. This dataset contains a subset of the entire AFLUX dataset (which will be made available later) and represents a section during the 11 April 2019 flight. This dataset contains different parameters relevant for the included estimates of cloud radiative forcing, like a cloud equivalent liquid water path equivalent derived from the shortwave transmissivity, or a cloud-free albedo estimate during cloudy observations.
