The Institute of Environmental Physics (IUP) at the University of Bremen offers a 3-year PhD position (f/m/d) German federal pay scale E13 TV-L (75%) in the research area for an integrated Greenhouse Gas (GHG) monitoring system (via satellite CO2 observations).

The time limitation is subject to the scientific qualification according to the Act of Academic Fixed-Term Contract, §2 (1) (WissZeitVG – Wissenschaftszeitvertrags-gesetz). Therefore, candidates may only be considered if they dispose of the respective scope of qualification periods according to §2 (1) WissZeitVG.

Emissions of the greenhouse gas carbon dioxide (CO2) are the primary cause of man-made climate change. Satellites are used to measure the global distribution of atmospheric CO2. The department "Physics and Chemistry of the Atmosphere" of the Institute of Environmental Physics (IUP) of the University of Bremen is a leading international research group in this field (

At the end of 2019, the European Space Agency ESA decided to implement the CarbonSat concept proposed by the University of Bremen. The planned Copernicus CO2M mission is to be launched in 2025. We are preparing for CO2M using existing satellite data.

For this purpose, we are looking for a committed young scientist to determine CO2 emissions from OCO-2 and OCO-3 CO2 satellite data (see

The research work is part of the project RiGHGorous of the German Weather Service (DWD) and is carried out in cooperation with the Max–Planck-Institute for Biogeochemistry (MPI-BGC).


•A M.Sc. degree or equivalent in physics, geophysics, meteorology etc. with a grade point average better than B (English grade) or 2.0 (German grade).

•Very good knowledge in at least one of the following areas: satellite remote sensing, radiative transfer, inversion theory, numerical modelling of complex systems

•Very good programming skills in at least one high level programming language (ideally Python) and good knowledge of Linux (including shell scripting)

•A strong interest to work in the field of satellite remote sensing of the atmosphere

•Good communication skills as cooperation with various European partners is required
