Radiance fields of clouds and the Arctic surface measured by a digital camera during HALO-(AC)3

During the HALO-(AC)3 campaign performed in March/April 2022 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).
