Datasets

During the campaigns different instruments have been operated on various platforms in the framework of (AC)³. As platforms the Polar 5 and Polar 6 aircraft of the Alfred-Wegener-Institute for Polar- and Marine research and the HALO aircraft operated by the DLR have been used. More information on the aircaft can be found on HALO-AC3.

The overview below shows the datasets available via the intake catalog for each research flight.
