The Institute of Environmental Physics and Remote Sensing at the University of Bremen is offering a PhD position (TVL 13, 19.6 hours per week), starting as soon as possible for the duration of three years in the field of Remote Sensing of Halogen Oxides with the Sentinel 5 Precursor Satellite The Institute of Environmental Physics at the University of Bremen has been analysing satellite observations of atmospheric composition for more than 2 decades. One of the methods used is the Differential Optical Absorption Spectroscopy (DOAS) which enables the detection of a number of stratospheric and tropospheric trace gases, facilitating the evaluation of their spatial distributions, sources and sinks, as well as their changes over time. The European Sentinel 5 Precursor satellite (S5P) due for launch by the end of 2016 will provide the opportunity to retrieve atmospheric trace gases with unprecedented sensitivity and spatial resolution (http://www.tropomi.eu/). Starting from existing retrieval algorithms and software, the aim of this PhD is to develop and improve methods for the detection and quantification of atmospheric distributions of bromine oxide and iodine oxide using S5P data. Both BrO and IO have mainly natural sources and play important roles in atmospheric ozone chemistry. The satellite data will be validated and used for atmospheric case studies. This work is integrated in the other S5P activities at IUP Bremen as well as the (AC)3 project (http://ac3-tr.de/) funded by the Deutschen Forschungsgemeinschaft. Requirements: * A very good master in Physics or a related discipline * Very good knowledge in at least one higher programming language * Interest in atmospheric science and data evaluation * Good knowledge in spoken and written German and / or English * Good knowledge and experience in one or several of the fields Physics and Chemistry of the atmosphere, remote sensing, radiative transfer, data evaluation. The Institute of Environmental Physics offers a friendly working atmosphere and excellent working environment. The position is integrated into the S5P activities at IUP which are performed in collaboration with MPI Mainz. More information on the institute and the DOAS group can be found at http://www.iup.physik.uni-bremen.de/eng/ and http://www.doas-bremen.de. 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 direct applications and questions in electronic form until April 24, 2016 to Dr. Andreas Richter Institut für Umweltphysik Universität Bremen 28359 Bremen Deutschland firstname.lastname@example.org Please include standard documentation (CV, references, copies of diplomas, letter of motivation) and mention our reference A 54/16.
