Highly oxygenated organic molecules (HOMs) contribute substantially to the formation and
growth of atmospheric aerosol particles, which affect air quality, human health and Earth's …

Atmospheric aerosols and their effect on clouds are thought to be important for anthropogenic
radiative forcing of the climate, yet remain poorly understood 1 . Globally, around half of …

Knowledge about mass discrimination effects in a chemical ionization mass spectrometer (CIMS)
is crucial for quantifying, eg, the recently discovered extremely low volatile organic …

Nucleation of aerosol particles from trace atmospheric vapours is thought to provide up to
half of global cloud condensation nuclei 1 . Aerosols can cause a net cooling of climate by …

About half of present-day cloud condensation nuclei originate from atmospheric nucleation,
frequently appearing as a burst of new particles near midday 1 . Atmospheric observations …

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

A list of authors and their affiliations appears at the end of the paper New-particle formation
is a major contributor to urban smog 1 , 2 , but how it occurs in cities is often puzzling 3 . If the …

For atmospheric sulfuric acid (SA) concentrations the presence of dimethylamine (DMA) at
mixing ratios of several parts per trillion by volume can explain observed boundary layer new …

Iodic acid (HIO 3 ) 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 major fraction of atmospheric aerosol particles, which affect both air quality and climate,
form from gaseous precursors in the atmosphere. Highly oxygenated organic molecules (…
