PhD student: Modeling ozone in the Mediterranean region

Advertising institute: IEK-8 - Troposphere
Reference number: D055/2014, Chemistry, Physics, Meteorology

For a research project at the Institute of Energy and Climate Research – Troposphere, IEK-8, we are seeking a

PhD student (Chemistry, Physics, Meteorology or equivalent degree)

for a 3 year position starting in summer 2014.

With 4400 staff members Forschungszentrum Jülich is the largest interdisciplinary research center in Germany focusing its research in the fields of health, environment and energy, and information technology. At IEK-8:Troposphere simulation chamber experiments, experimental field studies, and model calculations are used to investigate the processes that control the chemical transformation and spatial distribution of trace compounds, and their ultimate removal from the atmosphere. About 60 scientists, engineers, technicians and doctoral students are currently working at the institute in the field of atmospheric chemistry.

The research group “Global Modeling” of IEK-8 develops and runs a comprehensive global model for atmospheric chemistry, aerosols and climate and investigates the feedbacks between air pollution and climate change. The group is involved in various international research activities and collaborates with various partner institutes in Germany and elsewhere. Other group activities include the coordination of a sub project within the Copernicus atmospheric service (MACC) and leadership of WMO Global Atmosphere Watch scientific advisory group on reactive gases. Contributions to such group activities would be appreciated.

Science and Experiments within the PhD thesis
Current global chemistry climate models and regional air quality models show large biases in their simulations of tropospheric ozone in the Mediterranean region with a tendency to overestimate surface ozone concentrations. We would like to investigate the underlying causes for these modeling biases and, in a second step, use an improved model to assess the climate chemistry interactions related to tropospheric ozone in the Mediterranean region.


  • careful statistical analysis of available data sets from field campaigns and monitoring stations,
  • interpretation of numerical model results from ongoing international projects
  • set-up and execution of high-resolution sensitivity simulations with the chemistry climate model ECHAM6-HAMMOZ.


  • M. Sc. (or equivalent) in physics, chemistry, or a comparable discipline with a good final grade (in the German system 2.0 or better
    at least basic knowledge of atmospheric chemistry
  • excellent programming skills
  • experience with the analysis of complex data sets is advantageous
  • willingness to communicate research results and to interact within an interdisciplinary and international research environment are expected
  • ability to work independently and structured
  • Fluent knowledge of English language is required

We Offer:

  • A diverse international and motivated research team
  • Excellent technical support and access to supercomputing facilities
  • A well-organized PhD work including participation in the interdisciplinary HITEC graduate school on energy and climate research
