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 …

Uncertainty in the representation of biomass burning (BB) aerosol composition and optical
properties in climate models contributes to a range in modeled aerosol effects on incoming …

The effect of anthropogenic aerosols on cloud droplet concentrations and radiative
properties is the source of one of the largest uncertainties in the radiative forcing of climate …

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 …

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 …

Fundamental questions remain about the origin of newly formed atmospheric aerosol
particles because data from laboratory measurements have been insufficient to build global …

Nanoparticle emissions from road vehicles have been studied extensively in the recent past
due to their dominant contribution towards the total airborne particle number concentrations …

This paper synthesizes the available scientific information connecting atmospheric
nucleation with subsequent cloud condensation nuclei (CCN) formation. We review both …

Post-industrial increases in atmospheric black carbon (BC) have a large but uncertain
warming contribution to Earth's climate. Particle size and mixing state determine the solar …
