Job Offer from October 12, 2026

The Max Planck Institute for Biogeochemistry (MPI-BGC) in Jena is dedicated to interdisciplinary fundamental research in the field of Earth system sciences with a focus on climate and ecosystems. The internationally renowned institute, which currently employs around 250 people, celebrated its 25th anniversary in 2022. Jena is known for its high-tech industry, internationally renowned research institutions and a modern university, but it also has a beautiful natural setting in the green Saale valley with steep limestone slopes. The city of Jena has an active student scene and a diverse cultural life. We are looking for a Postdoctoral scientist (m/f/d) in full-time employment for a 12-month limited period, on atmospheric inverse modeling to constrain high-latitude greenhouse gas budgets.

Background and position description

High latitude ecosystems play a pivotal role in the global carbon cycle. Future climate change threatens to destabilize enormous carbon reservoirs stored currently in northern permafrost soils, with the potential to trigger strong feedback processes between climate and the carbon cycle that further amplify climate change. Still, large knowledge gaps remain regarding environmental conditions and mechanisms that control the carbon budgets of high-latitude ecosystems. This is particularly the case for methane and nitrous oxide emissions, which contribute an important fraction of the global warming potential resulting from carbon emissions to the atmosphere from many Arctic regions. A key uncertainty in this context is the role of landscape disturbances and non-linear change processes, triggered e.g. by thawing of ground ice and subsequent surface degradation, which also influence the hydrologic regime in permafrost regions, and therefore the fraction of greenhouse gases emitted.

We seek a postdoctoral scientist (m/f/d) with experience in atmospheric inverse modeling to constrain exchange fluxes of greenhouse gases between the land surface and the atmosphere. The successful candidate will join a multi-disciplinary research project funded by the German Ministry for Research, Technology and Space, aiming at investigating greenhouse gas processes with observational programs across spatio-temporal scales, and integrate these new datasets into biogeochemical process modeling and atmospheric simulations. The position will be embedded within an interdisciplinary research team at MPI-BGC that is conducting experimental, observational and modelling studies focusing on Arctic carbon cycle processes under global climate change.

Your tasks

• Maintain and upgrade an existing scheme for global-scale atmospheric inverse modeling, CarboScope , for state-of-the-art simulations of CH 4 and N 2 O fluxes in support of top-down greenhouse gas budgets synthesized by the Global Carbon Project.
• Exploit multi-disciplinary data sources to inform regional-scale inversions over selected boreal and Arctic domains, including, e.g., surface-based and airborne observations from recent monitoring campaigns in NW Canada, isotopic datasets, or satellite retrievals.
• Link short- and mid-term trends in high-latitude atmospheric greenhouse gas mixing ratios to dynamic land surface processes, with a particular focus on explaining enhanced growth rates in regional atmospheric greenhouse gases in recent years.
• Conduct atmospheric inversions to evaluate the performance of upgraded biosphere process models for greenhouse gas fluxes in high northern latitude regions, provided by project partners. The interpretation of process model results will be conducted jointly with project team colleagues contributing modeling results and in situ measurements.

Your profile

• Higher education degree (PhD) in atmospheric or natural sciences (e.g. meteorology, geo-ecology or other geo-science, or environmental physics)
• Experience in constraining surface-atmosphere exchange processes with atmospheric approaches is a prerequisite
• Experience in atmospheric transport modeling, observation and interpretation of time series of greenhouse gas mixing ratios, and inverse optimization techniques is essential
• Solid experience in scientific programming is a strong plus
• Demonstrated insights into Arctic ecology or carbon cycle science are considered beneficial
• We seek a flexible and proactive person (m/f/d) who can work both independently as well as in a larger team
• Very good written and spoken English is essential
