Abstract As we approach the end of the second decade of the 21st century, changes in atmospheric chemical composition due to anthropogenic pollution continue to challenge the well-being of society. The IUPAC effort in atmospheric chemistry data evaluation can be traced back over 40 years. Global concerns over potentially catastrophic stratospheric ozone depletion resulting from emissions of chlorofluorocarbons (CFCs) led to the creation of the CODATA Task Group on Chemical Kinetics in 1977. The task of the CODATA group was to provide the evaluated kinetic data for atmospheric reactions needed to assess the threat to stratospheric ozone. In 1989, sponsorship of the data evaluation effort was transferred to IUPAC, leading to the formation of the IUPAC Task Group on Atmospheric Chemical Kinetic Data Evaluation.

Abstract. This article, the seventh in the series, presents kinetic and photochemical data sheets evaluated by the IUPAC Task Group on Atmospheric Chemical Kinetic Data Evaluation. It covers an extension of the gas-phase and photochemical reactions related to Criegee intermediates previously published in Atmospheric Chemistry and Physics (ACP) in 2006 and implemented on the IUPAC website up to 2020. The article consists of an introduction, description of laboratory measurements, a discussion of rate coefficients for reactions of O3 with alkenes producing Criegee intermediates, rate coefficients of unimolecular and bimolecular reactions and photochemical data for reactions of Criegee intermediates, and an overview of the atmospheric chemistry of Criegee intermediates. Summary tables of the recommended kinetic and mechanistic parameters for the evaluated reactions are provided. Data sheets summarizing information upon which the recommendations are based are given in two files, provided as a Supplement to this article.

Abstract. This article, the sixth in the ACP journal series, presents data evaluated by the IUPAC Task Group on Atmospheric Chemical Kinetic Data Evaluation. It covers the heterogeneous processes involving liquid particles present in the atmosphere, for which uptake coefficients and adsorption parameters have been presented on the IUPAC website since 2009. The article consists of an introduction and guide to the evaluation, giving a unifying framework for parameterisation of atmospheric heterogeneous processes. We provide summary sheets containing the recommended uptake parameters for the evaluated processes. The experimental data on which the recommendations are based are provided in data sheets in separate appendices for the four surfaces considered: liquid water, deliquesced halide salts, other aqueous electrolytes and sulfuric acid.
