Research Foci

 

Our research foci are dedicated to air quality-related subjects in urban areas and its interaction with adjacent regions. This research accounts for local emission strategies and global to regional climate scenarios. The results provide the bases for health impact studies, societal assessment studies and cost-benefit analysis.

Impact of anthropogenic, geogenic and biogenic emissions on urban air quality

 

Improvement of the state of knowledge of chemical processes and assessment of the interaction of anthropogenic, geogenic and biogenic emissions in urban agglomerations. Further development of models by parameterization and evaluation of model components (emission, chemical transformation, dispersion, deposition)
 

Urban-rural interactions within a changing climate

 

Focus will be given to the formation of aerosols, the transportation and deposition in the “reaction vessel” of urban-rural regions within a changing climate. Online coupled climate-chemistry and air quality simulations (WRF/chem, COSMO-Art) in combination with micro scale modeling (GRAMM, GRAL) will investigate the distribution of aerosols from the urban to the regional scale.  High resolution land use information and improved BVOC emission schemes have to be considered to discriminate anthroposphere and biosphere dominated emission sources (like parks, greens, streets, living and industrial districts as well as land use changes due to the future change of energy production).


Mitigation and adaptation strategies

 

In order to support decision makers with scientifically sound knowledge the societal challenge is on the derivation of mitigation and adaptation strategies to reduce the negative impact of cities on human welfare. Such questions can only be answered within a cross-disciplinary strategy, combining modeling exercises and field experiments.
