Journal ArticleDOI
On the role of iodine in ozone depletion
TL;DR: In this paper, the authors speculate that iodine chemistry in combination with trends in anthropogenic chlorine and bromine may also be a factor in determining the widespread current depletion of lower stratospheric ozone.
Journal ArticleDOI
Heterogeneous reactions in sulfuric acid aerosols: A framework for model calculations
TL;DR: In this article, a framework for applying rates of heterogeneous chemical reactions measured in the laboratory to small sulfuric acid aerosols found in the stratosphere is presented, and the procedure for calculating the applicable reactive uptake coefficients using laboratory-measured parameters is developed.
Journal ArticleDOI
Atmospheric chemistry of small organic peroxy radicals

TL;DR: In this paper, the atmospheric chemistry of the four most abundant organic peroxy radicals (CH3O2, C2H5O2 and CH3C(O)O2) was evaluated.
Journal ArticleDOI
Measurement of hydroxyl and hydroperoxy radical uptake coefficients on water and sulfuric acid surfaces
TL;DR: In this paper, a wetted wall flow tube was used to measure the uptake coefficients, γ, of OH and HO 2 on pure water at 275 K and 28% w/w sulfuric acid at 249 K.
