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 …

New particle formation (NPF) represents the first step in the complex processes leading to
formation of cloud condensation nuclei. Newly formed nanoparticles affect human health, air …

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 …

Clouds play an important role in Arctic amplification. This term represents the recently
observed enhanced warming of the Arctic relative to the global increase of near-surface air …

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

Abstract The Arctic CLoud Observations Using airborne measurements during polar Day
(ACLOUD) campaign was carried out north-west of Svalbard (Norway) between 23 May and …

Volatile organic compounds (VOCs) play a vital role in the global carbon budget and in the
regional formation of ozone in the troposphere, and are emitted from both natural and …

Polar oceans and sea ice cover 15% of the Earth's ocean surface, and the environment is
changing rapidly at both poles. Improving knowledge on the interactions between the …

Summertime Arctic aerosol size distributions are strongly controlled by natural regional
emissions. Within this context, we use a chemical transport model with size-resolved aerosol …
