Two postdoc positions in high resolution polar climate modelling (1.0 FTE)

Job description

The climate of the polar regions is changing and will continue to change more in the future. These changes directly affect local communities, but indirectly also the rest of the world by changed weather patterns, enhanced global warming, and/or rising sea levels. Despite our growing understanding of the Earth’s climate and increasing computer calculation power, projections are surrounded by uncertainties. We don’t know how fast and to which extent humankind can reduce greenhouse gas emissions. It is also unknown, for example, if the general circulation patterns in the Northern Hemisphere will change in a warmer climate with reduced sea ice; or if the Antarctic sea ice will decline in the future as all GCMs predict virtually, unlike what we have witnessed in the past four decades in which the Antarctic sea ice underwent no structural change.
As the successful applicant(s) in this project, within in the European project PolarRES, you will study various aspects of the complex polar atmosphere-ocean-ice system from an atmospheric perspective and derive and analyse projections of the future climate of both polar regions, using various emission pathways and climate change storylines. The core model in this project is the state-of-the-art polar regional climate model RACMO2. In addition, the non-hydrostatic version of HCLIM will be used.
The project can be broken into two closely linked projects. The first project starts with optimizing the latest RACMO2 version for the PolarRES core tasks, and, possibly, refining a few polar-related physical processes. Next, high-resolution simulations of the contemporary climate are derived and analysed with, for example, a focus on clouds. Finally, storyline-based high-resolution projections for either Antarctica or the Arctic are made and analysed. The second project starts with exploring HCLIM for a region in West Antarctica, with a focus on the interaction between orography and precipitation and atmosphere-ocean-sea ice processes. In the second phase, storyline-based projections with RACMO are derived and analysed for either the Arctic or Antarctica.
These positions are part of PolarRES, an EU funded H2020 project. International collaboration with the PolarRES partners concerning model support, model analysis, and dissemination is an integral part of these projects.
We aim to start the project on 1 September 2021.


Our ideal candidate is driven, positive, and collaborative and has:

  • a PhD in regional climate modelling or earth-system modelling with a focus on polar atmospheric processes;
  • strong programming skills (Fortran, Python or similar);
  • thorough experience in running regional or global climate models;
  • affinity with numerical model development;
  • good reporting and presentation skills;
  • excellent level of written and spoken English; 
  • the ability to work both independently and within a wider research team;
  • the ability to critically assess your own results.

  • a full-time position for 2.5 to 3 years;
  • an inspiring and open-minded research group;
  • a job with national and international collaboration;
  • a full-time gross salary ranging from €2,790 to €4,402 in scale 10;
  • benefits including 8% holiday bonus and 8.3% end-of-year bonus;
  • a pension scheme, partially paid parental leave, and flexible employment conditions based on the Collective Labour Agreement Dutch Universities (cao).


In addition to the employment conditions laid down in the cao for Dutch Universities, Utrecht University has a number of its own arrangements. For example, there are agreements on professional development, leave arrangements, and sports. We also give you the opportunity to expand your terms of employment via the Employment Conditions Selection Model. This is how we like to encourage you to continue to grow.

About the organization

The Institute for Marine and Atmospheric Research Utrecht (IMAU) offers a unique research and teaching environment, in which the fundamentals of the climate system are studied. Research is organized in five themes: Atmospheric Dynamics, Atmospheric Physics and Chemistry, Coastal and Shelf Sea Dynamics, Ice and Climate, and Oceans and Climate. In 2017, IMAU research quality and impact were qualified as 'world leading' by an international visitation committee. Currently, IMAU employs 15 faculty members and 10 support staff, and about 20 Postdocs and 30 PhD candidates.
The Ice and Climate group at IMAU is an inspiring, high-quality, and versatile research group focusing on ice sheets, sea level, and climate. The group is world-leading in modelling of the ice sheet surface including firn, and maintains a dedicated network of automatic weather stations. Currently our research group has 5 staff members, 10 Postdocs, and 8 PhD candidates. For this project, we encourage and provide financial support for visits to conferences, workshops, and summer schools, and we promote national and international exchange visits.
At the Faculty of Science , there are 6 departments to make a fundamental connection with: Biology, Chemistry, Information and Computing Sciences, Mathematics, Pharmaceutical Sciences, and Physics. Each of these is made up of distinct institutes that work together to focus on answering some of humanity’s most pressing problems. More fundamental still are the individual research groups – the building blocks of our ambitious scientific projects.
Utrecht University is a friendly and ambitious university at the heart of an ancient city. We love to welcome new scientists to our city – a thriving cultural hub that is consistently rated as one of the world’s happiest cities. We are renowned for our innovative interdisciplinary research and our emphasis on inspirational research and excellent education. We are equally well-known for our familiar atmosphere and the can-do attitude of our people. This fundamental connection attracts Researchers, Professors and PhD candidates from all over the globe, making both the university and the Faculty of Science a vibrant international and wonderfully diverse community.
