The Arctic warms nearly four times faster than the global average, and aerosols play an
increasingly important role in Arctic climate change. In the Arctic, sea salt is a major aerosol …

Frequency and intensity of warm and moist air-mass intrusions into the Arctic have
increased over the past decades and have been related to sea ice melt. During our year …

Summertime wildfire activity is increasing in boreal forest and tundra ecosystems in the
Northern Hemisphere. However, the impact of long range transport and deposition of wildfire …

Ice-nucleating particles (INPs) can initiate ice formation in clouds at temperatures above-
38∘ C through heterogeneous ice nucleation. As a result, INPs affect cloud microphysical …

The Arctic environment has changed profoundly in recent decades. Aerosol particles are
involved in numerous feedback mechanisms in the Arctic, eg, aerosol-cloud/radiation …

Despite the key role of the Arctic in the global Earth system, year-round in-situ atmospheric
composition observations within the Arctic are sparse and mostly rely on measurements at …

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 …

The Arctic is warming two to three times faster than the global average, and the role of
aerosols is not well constrained. Aerosol number concentrations can be very low in remote …

We present an Arctic aerosol optical depth (AOD) climatology and trend analysis for 2003–
2019 spring and summertime periods derived from a combination of multi-agency aerosol …

Lagrangian tracer simulations are deployed to investigate processes influencing vertical and
horizontal dispersion of anthropogenic pollution in Fairbanks, Alaska, during the Alaskan …
