PhD position – Understanding the Transport of Aerosol Particles in the Upper Troposphere and Lower Stratosphere and Their Interaction with Ice Clouds Full-time

Aerosol Particles Research Position

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

Your Profile:

The following requirements are for the ideal candidate:

• Master's degree in meteorology, physics, environmental science or similar
• Knowledge of atmospheric dynamics and chemistry would be an advantage
• Good experimental skills and interest in working with custom-built or modified instruments
• Solid programming skills (e.g. Python) are desirable
• Ability to work independently and self-reliantly, while maintaining strong teamwork and collaboration skills
• Fluent in English

Please feel free to apply for the position even if you do not have all the required skills and knowledge. We may be able to teach you missing skills during your induction.
