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 …

This review intends to critically assess recent findings related to nucleation and growth of
atmospheric nanoparticles, with an emphasis on the understanding of these processes at a …

Atmospheric aerosols and their effect on clouds are thought to be important for
anthropogenic radiative forcing of the climate, yet remain poorly understood. Globally …

Nucleation of aerosol particles from trace atmospheric vapours is thought to provide up to
half of global cloud condensation nuclei. Aerosols can cause a net cooling of climate by …

Atmospheric aerosols exert an important influence on climate through their effects on
stratiform cloud albedo and lifetime and the invigoration of convective storms. Model …

Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air, and an
acknowledged risk to human health. Globally, the major source for urban outdoor UFP …

Iodic acid (HIO3) is known to form aerosol particles in coastal marine regions, but predicted
nucleation and growth rates are lacking. Using the CERN CLOUD (Cosmics Leaving …

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 …

The main nucleating vapor in the atmosphere is thought to be sulfuric acid (H2SO4),
stabilized by ammonia (NH3). However, in marine and polar regions, NH3 is generally low …

Cloud condensation nuclei (CCN) are derived from particles emitted directly into the
atmosphere (primary emissions) or from the growth of nanometer-sized particles nucleated …
