Topographic Effects of Svalbard on Warm and Moist Air Intrusions into the Central Arctic Open
Warm air intrusions (WAIs) along the North Atlantic pathway are key drivers of warm extremes in the central Arctic. The Svalbard archipelago acts as a major topographic barrier in the middle of this gateway, but its role in modulating WAIs…

Particle flux–gradient relationships in the high Arctic: emission and deposition patterns across three surface types Open
The Arctic is experiencing a warming much faster than the global average and aerosol–cloud–sea–ice interactions are considered to be one of the key features of the Arctic climate system. It is therefore crucial to identify particle sources…

Evolution of the size and composition of ice nucleating particles within the synoptic context of the Arctic melt onset Open
The Arctic region is undergoing rapid changes caused by a warming climate and positive radiative feedback loops associated with rapidly-declining sea ice. Clouds play a key role in melt onset timing and annual extent of sea ice loss by mod…

Influence of free tropospheric aerosols on the microphysical properties of a coupled low-level cloud in the central Arctic: a case study from the ARTofMELT expedition.  Open
Low-level mixed-phase clouds (LLMPCs) containing both ice and supercooled liquid water are ubiquitous in the Arctic and play a crucial role for radiative fluxes. Mixed-phase clouds are inherently instable due to the competition over water …
