Trace gases and aerosols play a key role in atmospheric physics and chemistry via homogeneous and heterogeneous chemical reactions, phase transitions, and interaction with radiation. The department investigates the distribution of trace species in the atmosphere from the troposphere to the mesosphere and the processes involved. This includes the characterization of natural and anthropogenic emissions (e.g. NOx from lightning, emissions of jet engines, methane from oil extraction facilities) and the investigation of transport and transformation processes. For this purpose, in-situ measurement techniques for trace gases, ions, and aerosols are developed and deployed from different platforms (research aircraft, Lufthansa in-service aircraft, balloons, rockets, UAVs). In addition, accompanying model simulations are performed.
Current reasearch activities focus on:
For this purpose, the following in situ measurement systems are applied
The department also hosts the young investigator’s group “Greenhouse gases” which focusses on in-situ measurements and remote sensing of CH4, CO2, and N2O.
In addition, the department performs coordination and service activities, e.g. maintaining of the HALO database, chair of the international SPARC/IGAC activity ACAM (Atmospheric Composition and the Asian Monsoon).
