The data set contains the cloud mask and cloud top altitude derived from measurements with the Airborne Mobile Aerosol Lidar (AMALi; Stachlewska et al., 2010) operated on board the Polar 5 research aircraft during 11 flights of the HALO-AC3 airborne campaign carried out in early spring 2022 northwest of Svalbard (Norway). The measurement campaign is embedded in the Transregional Collaborative Research Centre TR 172 (ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback Mechanisms (AC)3. It should be considered that the measurements have not been corrected for aircraft attitude. The data set has been quality-checked and is available in NetCDF format for each flight separately.
