Empa is a Swiss Science and Technology Institution of the ETH-Domain. The Laboratory for Air Pollution / Environmental Technology has an opening for a

 

PhD Candidate on
Real-time atmospheric measurements of N2O isotopomers to identify sources and hot spots in northern Switzerland

 

The PhD project is embedded in multi-disciplinary research, in co-operation with the KIT in Garmisch-Partenkirchen (Dr. Ralf Kiese, Prof. Dr. Klaus Butterbach Bahl), which aims at the identification of N2O source regions and processes in northern Switzerland. The PhD candidate at Empa will focus on real-time analysis of N2O isotopomers by laser spectroscopy. In an initial laboratory phase, the student will improve the performance of our analytical technique with respect to sensitivity and precision at ambient mixing ratios. In an extended field campaign, N2O isotope measurements at the Beromünster tall tower will be made for the first time. The on-site applicability of the instrument to distinguish N2O production processes will be demonstrated at different spatial scales. The results will be combined with atmospheric modelling to determine the temporal and spatial variability of N2O source strengths and isotopic signatures in northern Switzerland. In a complementary bottom-up approach, N2O isotope measurements will be used to validate biogeochemical soil models developed in a coordinated PhD project at KIT.

 

We are looking for a highly motivated PhD candidate with a Master’s degree in chemistry, environmental sciences or a related discipline, and a strong interest in isotope analysis, instrumental development and data analysis. We expect excellent English language skills, knowledge of German would be advantageous.
