The published data set consists of measurements performed by the active cloud radar as part of the Microwave Radar and radiometer for Arctic Clouds (MiRAC; Mech et al., 2019) operated on board the Polar 6 research aircraft during 6 flights of the HAMAG (Humidity profiles and Arctic Mixed-phase clouds as seen by Airborne W- and G-band radars) airborne campaign, carried out in February 2024 out of Kiruna (Sweden). 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. The published data set comprises radar reflectivities from the FMCW 94 GHz cloud radar and brightness temperature measurements at 89 GHz, both with a 25-degree backward inclination relative to the aircraft's fuselage. The dataset has been quality-checked and is available in NetCDF format for each flight. Details on the instrument can be found in Mech et al. (2019).
