Postdoc in coupled climate and terrestrial carbon cycle modeling

Updated: 3 months ago
Job Type: FullTime
Deadline: 22 Mar 2023

The Department of Environmental Science at Aarhus University (AU-ENVS), Roskilde, invites applications for a 2.5 year position as postdoc in coupled climate and terrestrial carbon cycle modeling. The position is to be filled by September 1, 2023 or as soon as possible thereafter. This is subject to negotiation.

Description of the position

This position is part of the 

GreenFeedBack project (Greenhouse gas fluxes and Earth system Feedbacks)

 funded under the Horizon Europe framework.  The GreenFeedBack project is led by AU-ENVS and brings together scientists doing fieldwork and modelers from across Europe. The aims are to enhance our knowledge of greenhouse gas (GHG) fluxes within terrestrial, freshwater, and marine ecosystems at high northern latitudes. In the project, we will investigate the impacts that human pressures have on ecosystem GHG fluxes, how the GHG fluxes will respond to a changing climate, and how changes to ecosystem GHG exchanges in the boreal and Arctic regions affect feedbacks in the global system.

This postdoc project is within work package 6 focusing on the latter, namely how high-latitude ecosystem responses feed back onto the global carbon cycle and modulate projected climate changes. The specific focus of the postdoc will be to use the coupled earth system model EC-Earth (v3 to begin with, perhaps transitioning to v4) and implement the terrestrial carbon cycle model developments achieved in other work packages into the dynamic vegetation-terrestrial ecosystem component of EC-Earth, LPJ-GUESS, and perform global-scale sensitivity and future simulations. The work will be done in close collaboration with teammates from Uppsala University (working with EC-Earth on the marine carbon cycle) and GreenFeedBack partners locally at AU-ENVS (working with the land surface model ORCHIDEE) and at Lund University (working with LPJ-GUESS).


  • Phd in physics, chemistry, biology, geophysics, engineering, environmental science, or other disciplines with relevant specialization.
  • Experience developing and executing dynamical vegetation and ecosystem models and using them to study carbon cycle feedbacks.
  • Experience with programming in C++, Fortran or similar languages and executing large code complexes in script-based environments on high-performance computing resources.
  • Sharing code using Git, Subversion or other source code management tools.
  • Experience running either EC-Earth or another coupled climate or earth system model is an advantage.

Further requirements are English fluency, good writing and verbal communication skills and the ability to work independently and in an interdisciplinary international academic environment.

Applicants should hold scientific qualifications at the PhD graduate level and demonstrate publication activities. Participation in applying for external funding is an advantage, but not a requirement.


Please see below for guidance and formalities regarding the application procedure. Per default, the application system requires upload of

  • Cover letter – please state your reasons for applying and your relevant qualifications
  • Curriculum vitae
  • Degree certificate
  • Complete list of publications
  • Statement of research plans and research activities – please indicate your previous research and your intentions and visions with regard to carrying out the work involved in the position
  • Teaching portfolio – please be aware, however, that apart from possible supervision activities, teaching is not planned for this position

Department of Environmental Science


Department of Environmental Science

 is an interdisciplinary department under the Faculty of Technical Sciences at Aarhus University. The expertise of the department ranges from physics, chemistry, microbiology, social science, geography, economics, to policy analysis. Basic as well as applied research is conducted on some of the major challenges facing society, such as pollution and pollution control mechanisms, management of land, soil, water, air and biodiversity, protection of ecosystem services, and climate change. Advisory services within these areas are offered to ministries and other authorities. Currently, the department employs about 140 staff, postdocs and PhD students. We believe in values of equality, diversity and inclusion, and creating an attractive work/life balance. Further information can be found at


The selected candidate will be affiliated with the Section for Atmospheric Environment  in the Group of Atmospheric Modelling which includes expertise in, i.a., atmospheric physics and chemistry; mathematical and numerical methods and computer science; hemispheric-to-local scale transport and air-quality modelling with linkages to health effects; climate, ice sheet and vegetation modelling with a particular focus on Arctic climate feedbacks.

Work location

The place of work will be at Aarhus University, Frederiksborgvej 399, 4000 Roskilde, Denmark. The city of Roskilde ( is located approx. 30 km from Copenhagen. The area provides immediate access to a wealth of cultural and recreational pursuits.
