The Arctic environment is rapidly changing due to accelerated warming in the region. The
warming trend is driving a decline in sea ice extent, which thereby enhances feedback loops …

We analyzed long-term measurements of organic carbon, elemental carbon, and source-
specific organic tracers from 2017 to 2020 to constrain carbonaceous aerosol sources in the …

Airborne in-situ cloud measurements were carried out over the northern Fram Strait between
Greenland and Svalbard in spring 2019 and summer 2020. In total, 815 minutes of low-level …

The Milan metropolitan area in Northern Italy experiences historically severe particulate
matter pollution episodes characterized by high organic aerosol (OA) concentrations …

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 …

Wildfires in Siberia generate large amounts of aerosols, which may be transported over long
distances and pose a threat to the sensitive ecosystem of the Arctic. Particulate matter (PM) …

The Arctic is a rapidly changing ecosystem, with complex ice–ocean–atmosphere
feedbacks. An important process is new particle formation (NPF), from gas-phase …

Radiocarbon (14 C) analysis of carbonaceous aerosols is used for source apportionment,
separating the carbon content into fossil vs. non-fossil origin, and is particularly useful when …

Anthropogenic and natural emissions contribute to enhanced concentrations of aerosols in
the Arctic winter and early spring, with most attention being paid to anthropogenic aerosols …

Air quality improved due to a sudden reduction in the mass concentration of criteria
pollutants (PM2. 5, PM10, NOx, CO, SO2) except ozone (O3) over cities of the world during …
