The Arctic region is a harbinger of global change and is warming at a rate higher than the
global average. While Arctic warming is driven by increases in anthropogenic greenhouse …

The climate in the Arctic is changing faster than anywhere else on earth. Poorly understood
feedback processes relating to Arctic clouds and aerosol–cloud interactions contribute to a …

Abstract In the central Arctic Ocean the formation of clouds and their properties are sensitive
to the availability of cloud condensation nuclei (CCN). The vapors responsible for new …

From 4 years of observations from Barrow, Alaska, it is shown that the cloud radiative impact
on the surface is a net warming effect between October and May and a net cooling in …

Airborne particles affect human health and significantly influence visibility and climate. A
major fraction of these particles result from the reactions of gaseous precursors to generate …

The summertime Arctic lower troposphere is a relatively pristine background aerosol
environment dominated by nucleation and Aitken mode particles. Understanding the …

Accurately accounting for new particle formation (NPF) is crucial to our ability to predict
aerosol number concentrations in many environments and thus cloud properties, which is in …

One year of aerosol particle observations from Alert, Nunavut shows that new particle
formation (NPF) is common during clean periods of the summertime Arctic associated with …

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

The Arctic region is vulnerable to climate change and able to affect global climate. The
summertime Arctic atmosphere is pristine and strongly influenced by natural regional …
