Scientific Achievements

 
Combined sensitivity analysis with a Monte Carlo technique to find appropriate initial conditions for chamber experiments to determine kinetic parameters of gas-phase reactions at tropospheric mixing ratios of reactants in the large atmospheric simulation chamber SAPHIR (Karl, 2004, PhD Thesis).

Designed experiments to investigate the rate constants for the initial step of the oxidation of isoprene, a biogenic VOC released by vegetation, initiated by the reactive hydroxyl radical (OH) and by ozone (O3) in SAPHIR.

Based on an existing reaction scheme for the degradation of isoprene, Dr. Karl has developed a detailed pattern for the treatment of the isoprene oxidation products methacrolein (MACR) and methyl vinyl ketone (MVK). In a product study the formation yield of MVK and MACR in the OH-induced isoprene oxidation and the rate constant of their reaction with OH were determined under realistic atmospheric conditions.

 
In an intercomparison of seven dimethyl sulphide (DMS) oxidation chemical mechanisms for the marine boundary layer (MBL) it was demonstrated that high uncertainties remain in the understanding of DMS chemistry with implications for climate.

New European emission database (spatial resolution of 0.089×0.089 degrees) for biogenic VOC (BVOC) based on Geographic Information System (GIS) land use data and a literature review on emission factors and foliar biomass densities.

 
Incorporation of a module for formation of secondary organic aerosol (SOA) into a two-way nested global CTM and studied the role of isoprene as a precursor to SOA over Europe.

Development of the novel multicomponent aerosol dynamics model MAFOR (Karl et al., 2011; 2012). The model has been applied in studies on new particle formation over the Arctic Ocean.
