We are always interested in hearing from excellent post-doctoral or PhD program candidates.

The PhD position on the project mentioned here below has been filled:

Development of a cavity enhanced laser spectrometer for operation on-board a Lufthansa passenger airplane.

Project summary: This is a collaborative project with the research group of Dr. Andreas Zahn at the Karlsruhe Institute of Technology (KIT), Germany, within the framework of the European Research Infrastructure IAGOS-CARIBIC [1]. IAGOS-CARIBIC is a flying laboratory in a modified airfreight container that includes (currently 19) instruments for atmospheric measurements during flights on board of a commercial airliner. The objective of the project is to add an instrument based on optical-feedback cavity enhanced absorption spectroscopy (OFCEAS [2]) that will analyze the isotope ratios (D/H and ¹⁸O/¹⁶O) of water in the middle and upper troposphere. For the first time worldwide, this two-cavity instrument will analyze the isotopic composition in both water vapor and cloud particles (by using a dual air inlet configuration). A major scientific objective is to better understand climate-relevant processes and their long-term changes in the altitude range where the dominant part of Earth’s greenhouse effect is generated. Instrument development and characterization will take place in Grenoble, whereas the integration in the CARIBIC laboratory and the instrument operation on the (brand-new) Lufthansa Airbus A350-900 will be the responsibility of KIT Both Grenoble and KIT will be involved in all stages of the project.
