Growth of monodisperse, submicron aerosol particles exposed to SO2, H2O2, and NH3
TL;DR: The growth of monodisperse particles (0.07 to 0.5 µm) exposed to SO2, H2O2 and sometimes NH3 in purified air at 22 °C at relative humidities ranging from 25 to 75% were measured using the Tandem Differential Mobility Analyzer technique.

Drop size dependent sulfate distribution in a growing cloud
TL;DR: In this article, a simple entraining air parcel model including cloud microphysical and chemical processes is used to calculate the distribution of sulfate over the drop sizes under continental background conditions.

TL;DR: In this paper, controlled cloud chamber experiments were conducted to measure particle growth resulting from the oxidation of SO2 by O3 and H2O2 in cloud droplets formed on sulfuric acid seed aerosol.

Sulfur dioxide in coastal new England fog
TL;DR: In this article, the authors investigated the concentration and oxidation capacity of SO 2 at a sampling site on the coast of New England during six fog events in the year 1990, and found that SO 2 mixing ratio was usually in the range of a few parts per billion, and its variability during a single event was governed mostly by changes in air masses of different history and overall chemical composition, rather than chemical oxidation in cloud.

The importance of atmospheric ozone and hydrogen peroxide in oxidising sulphur dioxide in cloud and rainwater
TL;DR: In this paper, the authors used the experimental data to calculate the rate of sulphate formation in water droplets under atmospheric conditions for each of the three oxidants, i.e., ozone, ozone and hydrogen peroxide.

Mechanism of the homogeneous oxidation of sulfur dioxide in the troposphere
TL;DR: In this article, an evaluation of the existing kinetic data related to the elementary, homogeneous reactions of SO 2 within the troposphere is made, and a set of preferred values of the rate constants for these reactions is presented.

Kinetics of the oxidation of sulfite by hydrogen peroxide in acidic solution
M. R. Hoffmann,J. O. Edwards +1 more
TL;DR: In this article, the authors investigated the kinetics of sulfite by hydrogen peroxide over the pH range 4-8 and showed that the reaction probably proceeds via a nucleophilic displacement by H 2O_2 on HSO_3^- to form a peroxomonosulfurous acid intermediate which then undergoes a rate-determining rearrangement.
