This review focuses on the observed characteristics of atmospheric new particle formation
(NPF) in different environments of the global troposphere. After a short introduction, we will …

Mechanisms of Arctic amplification and Arctic climate change are difficult to pinpoint, and
current climate models do not represent the complex local processes and feedbacks at play …

New particle formation of liquid or solid nanoparticles from gas-phase precursors is a
decisive process in Earth's atmosphere and is considered one of the largest uncertainties in …

Motivated by the need to predict how the Arctic atmosphere will change in a warming world,
this article summarizes recent advances made by the research consortium NETCARE …

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 …

Atmospheric new particle formation (NPF) and growth significantly influences climate by
supplying new seeds for cloud condensation and brightness. Currently, there is a lack of …

Summertime Arctic shipboard observations of oxygenated volatile organic compounds
(OVOCs) such as organic acids, key precursors of climatically active secondary organic …

Observations addressing effects of aerosol particles on summertime Arctic clouds are
limited. An airborne study, carried out during July 2014 from Resolute Bay, Nunavut …

The change of the global climate is most pronounced in the Arctic, where the air temperature
increases two to three times faster than the global average. This process is associated with …

The summertime high Arctic atmosphere is characterized by extremely low aerosol
abundance, such that small natural aerosol inputs have a strong influence on cloud …
