About me

Research Motivation: The Earth System is changing and humans are involved in many ways. The current geological era has therefore been named 'The Anthropocene' instead of 'The Holocene'. There is an urgent need to efficiently monitor the changes and to provide scientific interpretations to society. Climate change, global-scale air pollution, and ozone layer depletion are the most pressing environmental issues directly related to the rapid changes in global atmospheric composition which are caused by unsustainable human activities.

Projects

The research is internationally oriented and is being carried out most efficiently within international research project teams funded by the EU or other international bodies. Running EU projects include GAIA-CLIM and PRIMAVERA. With respect to (satellite-based) monitoring of atmospheric composition please visit the dedicated project website.

Research

My research is on atmospheric composition with a focus on the ozone layer, air pollution, and the parameters that determine the oxidizing ('cleansing') capacity of the atmosphere. Methane and tropospheric ozone, mainly formed through enhanced methane, constitute a significant contribution to anthropogenic climate forcing next to CO2. Enhanced ozone levels at the surface are harmful for health and limits agricultural yields. TM5 is the global chemistry module of the Earth System model EC Earth. Two-way coupling of TM5 within EC Earth is implemented to improve the study of the interaction of past, present-day and future atmospheric composition changes with the other elements of the Earth system.
