Description

The IUPAC Task Group on Atmospheric Chemical Kinetic Data Evaluation is updating the evaluations for gas-phase and heterogeneous-phase processes and expanding its coverage to include aqueous-phase reactions. With the new expansion the task group will cover the full range of chemical and physical processes of importance in air quality and climate change atmospheric models.

A new website is being developed at the University of Paris to facilitate dissemination of the evaluations. The Group is seeking support for 3-day meetings to be held in June 2018 and June 2019 to: update data sheets; agree on recommendations for rate constants for gas-phase, liquid-phase, and heterogeneous processes; and discuss development of the website. The panel will review new data published in 2017/2018 and compile and submit for publication new data sheets and a summary of recommended kinetic data for gas-phase, aqueous-phase, and heterogeneous processes of atmospheric importance. These data are needed as inputs for the next generation of chemistry-climate models for Earth system analysis for global and regional applications.

The project addresses the following IUPAC Long-Term Strategic Goals:

  • IUPAC will provide leadership as a worldwide scientific organization that objectively addresses global issues involving the chemical sciences.
  • IUPAC will facilitate the advancement of research in the chemical sciences through the tools that it provides for international standardization and scientific discussion.
  • IUPAC will assist chemistry-related industry in its contribution to sustainable development, wealth creation, and improvement in the quality of life.

The recommended kinetic data for atmospherically relevant processes will be documented in the form of data sheets which will be uploaded to the web https://iupac.pole-ether.fr/ and published in a special issue of Atmos. Chem. Phys. here https://www.atmos-chem-phys.net/special_issue8.html.
