The Institute of Meteorology and Climate Research at the KIT offers a

Ph.D. student position

funded according to TVöD (75 %) for a period of 3 years

The Karlsruhe Institute of Technology (KIT) is one of the largest research facilities in Europe with more than 9000 employees. The Institute of Meteorology and Climate Research (IMK) employs ~200 scientists in four departments, covering research fields from biosphere-atmosphere gas exchange, tropospheric meteorology, aerosol and cloud physics to trace gas budgets and dynamics from the troposphere up to the mesosphere.

The group Tropopause (TOP) at the IMK is particularly interested in the budgets of trace gases in the upper troposphere and lower stratosphere (UTLS), a region which plays an essential role in controlling climate on Earth. We develop in-situ instruments for deploying them on board passenger and research aircraft. One project is on the German research aircraft HALO (High Altitude and LOng Range operated by the German Aerospace Centre) which is an exciting and challenging platform.

The upcoming HALO mission EMeRGe (Effect of Megacities on the Transport and Transformation of Pollutants on the Regional to Global Scales) is headed by IUP (Institute of Environmental Physics, University of Bremen) and funded by the Deutsche Forschungsgemeinschaft (DFG). Objective of EMeRGe is to study the pollution outflow and its chemical transformation from major population centres (MPCs). The mission is divided into two phases taking place at the DLR (Germany) in July 2017 and in Asia (presumably Taipeh) in April 2018. Within the framework of EMeRGe we are looking for a

Ph.D. Student (m/f)

in the field of atmospheric chemistry and  global pollution. The successful applicant will supervise a Proton-Transfer-Reactions Mass Spectrometer (PTR-MS) during EMeRGe, which was developed in our group over the last years. The PTR-MS measures volatile organic compounds (VOCs) such as acetone or methanol, both emitted from vegetation and anthropogenic activity. These species are, although being present in very low concentrations, directly linked to the formation of ozone and radicals. The work will focus on the characterization of VOC emissions from MPCs. One aim is to identify differences and commonalities in the transport and transformation of the plumes from European and Asian MPCs. The gathered data shall also be compared with model results from the new model ICON, in collaboration with the model group at the IMK.

Job description: The work consists of three work packages, i.e. (1) building up a calibration unit for VOCs and characterizing the PTR-MS in the laboratory before EMeRGe, (2) Deployment of the PTR-MS during the two HALO missions EMeRGe in Germany and Asia, and (3) Analyzing and interpreting the gathered data (also with support from the atmosphere model ICON) and publishing the findings in ISI-referenced journals.

Requirements: The position involves multi-disciplinary research with a high degree of work autonomy and the use of the latest technical equipment. You are a curious and adventurous mind with an above-average master degree or equivalent in physics, chemistry or meteorology. You should have a basic knowledge of atmospheric chemistry and programming skills in Matlab or in programming languages such as C, C++, or Python. Ideally, you have already gained experience with Proton-Transfer-Reactions Mass Spectrometry or with some other mass spectrometric technique. You should have a strong teamwork spirit, strong communication and organizational skills and an ability to effectively communicate results of scientific research to project members and international colleagues.

Qualification: Diploma or Master degree in physics, chemistry, meteorology or a related discipline

Salary: Remuneration is 50% above the Ph.D. standard scale (75% of TVöD-13).

Institute/Department: Institute of Meteorology and Climate Research (IMK)

Contract duration: 3 years

Starting date: as soon as possible
