The role aerosol chemical composition plays in Arctic low-level cloud formation is still poorly
understood. In this study we address this issue by combining in situ observations of the …

The aerosol particles serving as cloud condensation and ice nuclei contribute to key cloud
processes associated with cold-air outbreak (CAO) events but are poorly constrained in …

Cloud radar Doppler spectra are of particular interest for investigating cloud microphysical
processes, such as ice formation, riming and ice multiplication. When hydrometeor types …

Black carbon (BC) is a short-lived climate forcer affecting the Arctic climate through multiple
mechanisms, which vary substantially from winter to summer. Several models still fail in …

Ice-nucleating particles (INPs) initiate primary ice formation in Arctic mixed-phase clouds
(MPCs), altering cloud radiative properties and modulating precipitation. For atmospheric …

The representation of Arctic clouds and their phase distributions, ie, the amount of ice and
supercooled water, influences predictions of future Arctic warming. Therefore, it is essential …

Dimethyl sulfide (DMS), a gas produced by phytoplankton, is the largest source of
atmospheric sulfur over marine areas. DMS undergoes oxidation in the atmosphere to form …
