Research Group: Plant-Atmosphere Interactions

Projects & Collaborations


Research scope

The PAI group is interested in the interplay between terrestrial ecosystems, climate change and land-use change, focussing on regional-global scale questions and applications. We use advanced dynamic ecosystem modelling frameworks (e.g., LPJ-GUESS) coupled to Earth system models (e.g., EC-Earth) and models of land-use change. In the broadest sense, our research questions are:

  • How do climate change, change in atmospheric CO2 and land-use change individually and jointly affect the state and functioning of terrestrial ecosystems and (some of) the ecosystem services they provide?
  • Where is the impact of each of these drivers largest, and over which time horizon
  • Are there identifiable feedbacks in the ecosystem-landuse-climate change system?
  • What (and how large) are the chief uncertainties?









Research Group: Biological Processes of C- and N-Trace Gas Formation

Research Group Biological Processes

Aim of the Research Group is to understand biological processes involved in the complex exchange and interaction of reactive and climate sensitive C- and N-trace gases between biosphere and atmosphere. Thereby fundamental microbial and plant biological processes of C- and N-emission, storage and exchange of trace gases are analyzed with modern tools in biology (e.g. genetically-modifed organisms, cLSM) and analytical chemistry (e.g. online mass spectrometry) serving to develop process-based emission models and to understand biological and ecological functions of these compounds.
