Short summary
Dust from Greenlandic glacial outwash plains can form ice in clouds, a process relevant for climate. Its ice-nucleating activity varies strongly and is largely controlled by small amounts of biological material. During summer, the influence on atmospheric ice-nucleating particles is mostly local. Lower activity compared to other high-latitude dust sources highlights the need to account for regional differences in Arctic dust.
