We present three aircraft campaigns conducted with the research aircraft Polar 6, all using similar configurations for in situ aerosol and turbulence measurements. Two campaigns, BACSAM I (autumn 2022) and BACSAM II (spring 2024), were carried out in the Arctic from Longyearbyen. The third campaign, SANAT, will take place in early 2026 from Neumayer III Station in Antarctica. These measurements provide one of the first aerosol profile datasets collected in the vicinity of Neumayer III.
A comprehensive suite of aerosol instruments enables measurements of aerosol parameters such as number concentrations and size distributions, while the aircraft*s nose boom provides high-frequency (100 Hz) meteorological and turbulence data. During all three campaigns, the Turbulence-Bird (T-Bird) was also deployed up to 80 m below the aircraft, carrying additional aerosol and turbulence sensors allowing for simultaneous observations at two altitudes.
This unique setup enables investigations such as airborne particle fluxes. We present the three campaigns, outline the measurement setup, and show examples of the atmospheric conditions encountered.
