During the Airborne measurements of radiative and turbulent FLUXes of energy and momentum in the Arctic boundary layer (AFLUX) campaign in March/April 2019 a downward-looking commercial digital camera equipped with a 180° - fisheye lens was installed on the aircraft Polar 5. Images of the Arctic surface and clouds were taken every 4 - 6 seconds. The data set provides rectified fields of calibrated radiances along the flight track for the three spectral bands (red, green, and blue). ... : The data are stored in nc-file format. Each file contains one hour of radiance measurements for the three spectral channels. Time (UTC), flight altitude, longitude, latitude and the viewing angles are given as well. ...
