AB: An overview on recent developments in tropospheric multiphase chemistry studies is given. First, recent laser- based time-resolved studies of radical reaction kinetics in aqueous solution are described where reactions of the hydroxyl and nitrate radical with organic particle phase constituents have been investigated. Such measurements form the basis for the development of chemical mechanisms and the current state of the Chemical Aqueous Phase Radical Mechanism (CAPRAM) is being reviewed. Field experiments on aerosol-cloud-interaction have been performed at the Schmücke measurement site in the Thuringian Forest in Germany and results from these campaigns are being compared to model results. To conclude, currently open questions and possible further developments are discussed.
