Postdoc Researcher, climate modeling - Potsdam, Germany

The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) seeks a motivated candidate to fill a three-year Postdoctoral Researcher position in climate modeling and isotope research.


This position is part of the CiASOM project ("Changes of water isotopes in Arctic Sea ice, Ocean and atMosphere"). In this project, novel isotope data sets obtained during the MOSAiC expedition will be studied to better understand the Arctic water cycle and its future changes.

The aim of the CiASOM project is to investigate the different Arctic moisture sources and their contribution to the global water cycle and to quantitatively record relevant exchange processes between ocean, sea ice and atmosphere. To this end, stable water isotopes will be used as climate and environmental parameters for the study of the current water cycle and isotope measurements will be linked to high-resolution climate simulations. To carry out these climate simulations and to compare them with isotope data measured on FS Polarstern, we are looking for a PostDoc to start on on 1 November 2020 or as soon as possible. The research work is a central part of the CiASOM project and is carried out in close cooperation with the ISOLAB Facility by Dr. Hanno Meyer, AWI Potsdam.


This is a full-time position, limited to 3 years. It is also suitable for part-time employment. The salary will be paid in accordance with the Collective Agreement for the Public Service of the Federation (Tarifvertrag des öffentlichen Dienstes, TVöD Bund), up to salary level 13. The place of employment will be Bremerhaven.

 Postdocs can register with AWI’s postdoc office PROCEED, thereby gaining access to a set of tailor-made career development tools.


- A series of high-resolution climate simulations will be carried out using the atmosphere model ECHAM6, which includes explicit isotope diagnostics. These climate simulations will be used to link isotope measurements carried out on-board FS Polarstern and various Arctic land stations and to enable a common interpretation.
- For the intended model-data comparison, it is necessary to systematically process and analyse the water vapour isotope data measured with a CRDS instrument on FS Polarstern. In addition, it is planned to compile, standardise and prepare further isotope data sets from various Arctic land stations for comparison with the climate simulations carried out.


- PhD in the field of physics, meteorology, geo-sciences, climate sciences, or similar
- Experience with complex climate models (application and evaluation)
- Experience in the measurement and interpretation of stable water isotopes would be an advantage
- Proven programming skills (Fortran, Python)
- Proven publication activity in peer-reviewed journals
- Fluent English skills
- The skills to develop your own research questions and to tackle both scientific and technical challenges individually, while working well as part of a team


Applications close 21 October 2020.
