Greenhouse Gas and Water Isotopes



 


The main interest of the team is to investigate the cycle of atmospheric water and greenhouse gases such as CO2, CH4 and N2O. Through the study of atmospheric concentrations and isotopic composition of the above trace gases the group searches for a quantification of sources and sinks and atmospheric transport pathways. This is done through accurate atmospheric measurements on local to regional scales, including punctuated studies of sources and sinks. Further, radioactive tracers of atmospheric transport are used and physical processes steering isotope fractionation during the transport and transformation of water and atmospheric trace gases are studied. Moreover, conceptual transport models are developed. The group is involved in the verification of greenhouse gas emissions in cooperation with the Integrated Carbon Observation System (ICOS)


News

  • We congratulate Benjamin Lebegue for the successfull completion of his PhD at LSCE (Saclay), well done and all the best for the future
  • We are happy to annouce that the European Union has funded a Research training network in which we participate. We soon provide news for international master students regarding the PhD projects that will open in 2017 and the project to be conducted in our team.

Open positions

Presently we seek Bachelor and Master students for studies of water isotopes, its sources and its fundamental physical fractionation processes. Also students with study goal as higher eduction teacher (Staatsexamen) are highly welcome as we seek to develop new experiments regarding water isotope fraction in precipitation as part of the physics master course in environmental physics

Tools

To investigate the composition of the atmosphere and to study water vapor and precipitation we use tunable laser spectrometers and mass spectrometry. Data evaluation is based on atmospheric transport and gaussian plume models and programming in 'R'.
