Résumé des résultats (Abstract) (Anglais)

THALOZ is a concerted, multidisciplinary effort aimed at understanding of the role of reactive halogens in tropospheric oxidation chemistry, their effect on ozone, and consequent influence on irradiative forcing of climate by greenhouse gases. The work plan combines satellite observations, laboratory studies, model development and model application.

New information will be obtained on the amounts of reactive halogen species in the troposphere and on the key chemical reactions controlling them. The models will be used to assess the regional and global distribution and budgets of halogens and their effect ozone in the troposphere, and the changes irradiative forcing due to halogen chemistry.
