“…In combination with k ∞ , (see below) this expression accurately reproduces the data of Wine et al (1984), Paraskevopoulos et al (1983), and in N 2 at room temperature and covers the atmospheric pressure range without any extrapolation. The temperature dependence of k 0 was based on an analysis of data obtained in Ar, He and F 6 .…”

“…The reaction sequence HOSO 2 + O 2 → HO 2 + SO 3 and HO 2 + NO → HO + NO 2 then regenerates HO radicals. Modeling of the NO decay led to the rate coefficient k. This method of determining k is less direct than the more recent measurements of Gleason et al (1987) and Gleason and Howard (1988), where HOSO 2 radicals were monitored by MS. We therefore accept the temperature-dependent expression obtained by Gleason and Howard (1988). The earlier results Martin et al, 1986), though less precise, are in good agreement with the preferred values.…”

Evaluated kinetic and photochemical data for atmospheric chemistry: Volume I - gas phase reactions of Ox, HOx, NOx and SOx species

Abstract. This article, the first in the series, presents kinetic and photochemical data evaluated by the IUPAC Subcommittee on Gas Kinetic Data Evaluation for Atmospheric Chemistry. It covers the gas phase and photochemical reactions of O x , HO x , NO x and SO x species, which were last published in 1997, and were updated on the IUPAC website in late 2001. The article consists of a summary sheet, containing the recommended kinetic parameters for the evaluated reactions, and five appendices containing the data sheets, which provide information upon which the recommendations are made.

“…is believed to be rate limiting (Seinfeld and Pandis, 1998;Wine et al, 1984). Clearly complementary to this mechanism, a number of experimental and field based studies have found correlations between cosmic rays intensities and various cloud or aerosol parameters (Kirkby et al, 2011;Svensmark et al, 2009;Enghoff and Svensmark, 2008;Harrison and Carslaw, 2003).…”

Structures and reaction rates of the gaseous oxidation of SO2 by an O3−(H2O)0-5 cluster – a density functional theory investigation

Abstract. Based on density functional theory calculations we present a study of the gaseous oxidation of SO 2 to SO 3 by an anionic O − 3 (H 2 O) n cluster, n = 0-5. The configurations of the most relevant reactants, transition states, and products are discussed and compared to previous findings. Two different classes of transition states have been identified. One class is characterised by strong networks of hydrogen bonds, very similar to the reactant complexes. The other class is characterised by sparser structures of hydration water and is stabilised by high entropy. At temperatures relevant for atmospheric chemistry, the most energetically favourable class of transition states vary with the number of water molecules attached. A kinetic model is utilised, taking into account the most likely outcomes of the initial SO 2 O − 3 (H 2 O) n collision complexes. This model shows that the reaction takes place at collision rates regardless of the number of water molecules involved. A lifetime analysis of the collision complexes supports this conclusion. Hereafter, the thermodynamics of water and O 2 condensation and evaporation from the product SO
