The Institute of Environmental Physics and Remote Sensing at the University of Bremen is offering a PhD position (TVL 13, 50%), starting as soon as possible for the duration of three years in the field of

Satellite based remote sensing of halogens in the Arctic atmosphere

The Institute of Environmental Physics (IUP) at the University of Bremen, department of Prof. J. P. Burrows, has been analysing satellite observations of atmospheric composition for more than 2 decades. One of the methods applied is the Differential Optical Absorption Spectroscopy (DOAS) which enables the detection of a number of stratospheric and tropospheric trace gases, facilitating evaluation of their spatial distribution, sources and sinks, as well as their changes in time.

The (AC)3 project (, which is funded by DFG (Deutsche Forschungsgemeinschaft), investigates the increase in temperature in the Arctic and its consequences. Within the framework of this project, data products from different satellite remote sensors should be developed and, in addition to numerical model data, applied for investigating formation and spatial distribution of halogen oxides in the Arctic atmosphere. Major sources of atmospheric halogens are young sea ice (as it is highly concentrated in sea salt) and oceanic phytoplancton. The release of halogens to the atmosphere is also influenced by local weather conditions. Once released into the lower atmosphere, halogens can cause efficient depletion of ozone, which is a major greenhouse gas. As such, halogens indirectly impact on radiative properties of the atmosphere and in turn temperature of the Arctic. This work will be carried out in collaboration with other scientists at IUP and also from the Alfred-Wegener-Institute in Bremerhaven.

  • A master or diploma in physics or a related discipline
  • Very good knowledge of at least one higher programming language
  • Interest in data analysis and atmospheric research
  • Good knowledge in spoken and written German and / or English
  • Willingness to go on business trips
  • Good knowledge and experience in at least one of the following fields: physics and chemistry of the atmosphere, meteorology, remote sensing of the Earth system, analysis of numerical model data
The Institute of Environmental Physics offers a friendly working atmosphere and excellent working environment. The position is integrated into the national scientific framework of the DFG funded project (AC)3,. More information on the institute and the DOAS group can be found at and
As the University of Bremen intends to increase the proportion of female employees in science, women are particularly encouraged to apply. In case of equal personal aptitudes and qualification priority will be given to disabled persons.

Please send applications including standard documentation (CV, copies of diplomas, letter of motivation) in electronic form (pdf format, one file only) with reference to job advertisement number A 40/16 until 15.03.2016 to
