Highly oxygenated organic molecules (HOM) are formed in the atmosphere via autoxidation
involving peroxy radicals arising from volatile organic compounds (VOC). HOM condense on …

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 …

With the Arctic rapidly changing, the needs to observe, understand, and model the changes
are essential. To support these needs, an annual cycle of observations of atmospheric …

Atmospheric new particle formation (NPF) is an important global phenomenon that is
nevertheless sensitive to ambient conditions. According to both observation and theoretical …

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 …

A list of authors and their affiliations appears at the end of the paper New-particle formation
is a major contributor to urban smog,, but how it occurs in cities is often puzzling. If the …

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 …

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

About half of present-day cloud condensation nuclei originate from atmospheric nucleation,
frequently appearing as a burst of new particles near midday. Atmospheric observations …

Nitrate comprises the largest fraction of fine particulate matter in China during severe haze.
Consequently, strict control of nitrogen oxides (NO x) emissions has been regarded as an …
