TL;DR: How NOx suppresses particle formation is shown, while HOMs, sulfuric acid, and NH3 have a synergistic enhancing effect on particle formation, elucidate the complex interactions between biogenic and anthropogenic vapors in the atmospheric aerosol system.

TL;DR: Iodic acid (HIO3) is known to form aerosol particles in coastal marine regions, but predicted nucleation and growth rates are lacking as discussed by the authors Using the CERN CLOUD (Cosmics Leaving Outdoor Droplets) chamber, they find that the nucleation rates of HIO3 particles are rapid, even exceeding sulfuric acid-ammonia rates under similar conditions.

TL;DR: In this article, the authors show that a decrease in temperature (from +25 to −50 ∘ C) results in a reduced HOM yield and a reduced oxidation state of the products, whereas the increase in NPF rates (J 1.7nm ) increase substantially.

TL;DR: In this paper, the authors measured the growth rate of uncharged sulfuric acid particles from 1.8 to 10 µnm under atmospheric conditions in the CERN (EuropeanOrganization for Nuclear Research) CLOUD chamber.

TL;DR: It is found that pure biogenic nucleation and growth depends only weakly on temperature, and consistency between measured gas-phase product concentrations, product volatility, measured and modeled growth rates, and the particle composition over most temperatures found in the troposphere is established.
