The research group of Dr. Johannes Schneider (Max Planck Institute for Chemistry, Mainz) conducted in–situ composition measurements of aerosol particles and cloud residuals during the ACLOUD field campaign in May–June 2017. A single–particle laser ablation mass spectrometer was deployed on Polar 6 and connected to (a) the aerosol inlet for aerosol measurements, and (b) to a Counterlow Virtual Impactor (CVI) for cloud residuals. The results showed an enhanced abundance of particles from marine biogenic origin (Amines) in cloud residuals. For phase II of (AC)³ the group plans to contribute with aerosol and cloud residual measurements during the two MOSAiC airborne studies, scheduled for March/April 2020 and August/September 2020. Main scientific objectives are to understand the role of central–Arctic aerosol sources as well as the contribution of long–range transport to the Arctic aerosol and the influence of aerosol particles from various sources on Arctic cloud formation.
