Current research of the group combines the fields of meteorology and atmospheric chemistry and involves both experimental field work and numerical modeling. Main research targets include (1) the quantification of trace gas budgets (e.g. carbon monoxide [CO], volatile organic compounds [VOC], peroxides [RO2], nitrogen oxides [NOx], peroxyacyl nitrates [PANs], ozone [O3], sulfur dioxide [SO2]) in unpolluted and polluted areas, (2) determination of anthropogenic and biogenic contributions to the formation of secondary trace gases, and (3) the application and development of advanced chemistry-transport modeling.
These research issues encompass different scales ranging from biosphere-atmosphere exchange processes, to regional urban air quality studies and long-range transport studies. Thus they include various meteorological measurement tools to describe exchange and boundary layer processes (e.g. micrometeorological towers, tethered sondes, SODAR, RASS, radio- and ozonesondes etc.) and also involve airborne measurements.
One important research topic in the field of atmospheric chemistry addresses the role of specific VOC in the formation of secondary species on the background of differing VOC/NOx ratios and different VOC-mixtures (urban, rural). Another focus addresses atmospheric radical chemistry involving photochemical sensitive species such as formaldehyde [HCHO], hydrogen peroxide [H2O2] and nitrous acid [HONO]. The experimental trace gas data sets are used for the validation and development of photochemical box models as well as advanced chemistry-transport model approaches. The chemistry-transport models in turn help to identify processes inherent in the concurrent measurements of the various species.
These studies help to assess the oxidation capacity of the atmosphere, to enhance our understanding of atmospheric photochemical processes and to identify key species, their origins and their fates in the atmosphere.
