Job Description

The Global Monitoring Group in the Institute of Climate and Energy Systems - Troposphere (ICE-3) with expertise in aircraft-based trace gas, clouds and aerosol measurements is joining the Collaborative Research Centre TPChange, as funded by the German Research Foundation, for studying the tropopause region in a changing atmosphere. The TPChange project aims to specify the impact of the processes in the upper troposphere and lower stratosphere on composition, dynamics and ultimately on future climate and climate variability using a combination of field measurements, laboratory studies, theoretical approaches, and multiscale numerical modelling. Further information on the project is available at: DFG CRC TPChange https://tpchange.de/

Your Job:

Aerosol particles act as ice nucleating particles, providing surface for water vapour to deposit and freeze into ice particles. Formation of cirrus clouds and subsequent sedimentation of ice crystals can dehydrate air in the upper troposphere and lower stratosphere (UTLS) region, thereby influencing the water vapor budget of this region. Aerosols and cirrus are important to the global climate because they interact with radiation from the sun and from the earth. However, the aerosol-cirrus interaction in the UTLS is not well understood because of lacking sufficient in situ data. In addition, the dynamics and transport processes across the UTLS adds complexity to unveil the role of UTLS aerosols in cirrus formation and the life cycle of cirrus. Therefore, it is crucial to measure aerosol composition and properties together with cirrus occurrences in the UTLS for achieving a better understanding of the link between aerosols and cirrus clouds in the UTLS, for which Lagrangian modelling is a valuable tool to revealing the source of UTLS aerosols, the origin of water masses, and formation processes of cirrus particles.



Your key responsibilities include:



Preparation, operation, and calibration of aerosol, water vapour and cloud instruments through the research aircraft campaign Flight planning for aerosol and cirrus measurement missions using Lagrangian modelling Evaluation and interpretation of in-situ measurement data aided by Lagrangian trajectory calculations Presentation of results in international conferences and publication in peer-reviewed journals
