Heterogeneous Reactions

About

The "Heterogeneous Reactions" group is investigating the chemical formation of oxidized organic precursors, relevant for the formation of atmospheric aerosols and the coupling of those to atmospheric radical chemistry. The central analytical method is negative ion chemical ionization mass spectrometry. These studies are mainly performed in the atmospheric simulation chamber SAPHIR and in the new continuously stirred flow reactor SAPHIR* (SAPHIR-STAR, Stirred Atmospheric flow Reactor).

Research Topics

Because of their importance for the climate we also are also investigating the effects of aerosol chemistry on cloud droplet activation. For the latter we installed the aerosol sampling in three heights (120m, 50m, 10m) at the Meteorological Tower at FZJ. In close cooperation with the section "Global Monitoring", and the groups "Stabile Isotopes in Aerosols" and "Atmospheric Modelling", we are monitoring cloud droplet activation, aerosol optical properties and aerosol size distribution and aerosol composition.
