Triple element stable isotope signatures for constraining the atmospheric chloromethane budget
Goals
- Development of triple element isotope methods for measurements of atmospheric CH3Cl
- Potential for application in numerical modelling approaches
- A better understanding of the atmospheric CH3Cl budget is thus the major objective
Specifically
- Construction, optimization and testing of a large-volume air sampling system
- Collecting of atmospheric air samples at three different locations (Heidelberg University, Hohenpeißenberg (DWD weather station at the boundary layer) and Schneefernerhaus (research station located in the free troposphere)
- Sample collection at different times over a period of 1 year to monitor seasonal variations
- Erste Bewertungen der Anwendung der Messdaten, um das atmosphärische CH3Cl-Budget genauer zu bestimmen
