Open positions in the ICOS field
Postdoctoral Researcher, greenhouse gases and carbon cycle, Climate System Research unit, Finnish Meteorological Institute, Helsinki, Finland (deadline 25th September 2025)
The Climate System Research unit of the Finnish Meteorological Institute is seeking a postdoctoral researcher for a fixed-term three-year position in Helsinki to study greenhouse gases and the carbon cycle in agricultural and forest ecosystems.
Our unit conducts extensive field measurements, data analysis, and modelling in boreal conditions, with a particular focus on ecosystem carbon fluxes and soil carbon stock dynamics. We work in a multidisciplinary research environment that combines measurements, modelling, data analytics, and method development. We are now looking for an expert in greenhouse gas and/or carbon cycle research to strengthen our ongoing projects.
You may have expertise in one or more of the following areas:
• Eddy covariance (EC) measurements, data processing, and analysis
• Ecosystem and process modelling of the carbon cycle (e.g. carbon sequestration in agriculture and/or forestry and its climate impacts)
• Integration of remote sensing data with ecosystem modelling and/or ecological field data
• Application of machine learning methods to data analysis
• Statistical modelling of long time series
• Use of biogeochemical and process-based models
• Integration of the carbon cycle into climate roadmaps or land-use scenarios
Your work will include the planning, implementation, and reporting of research. You will also publish results in international peer-reviewed journals, participate in societal interaction and science communication, contribute, when possible, to the supervision of postgraduate students, and collaborate with national and international research networks.
Deadline for applications is 25th September 2025.
PhD position, Measuring photosynthesis and respiration in high time-resolution with eddy covariance and wavelet analysis, French National Research Institute for Agriculture, Food, and Environment (INRAE), Nancy, France (deadline 14th September 2025)
Land vegetation is currently under unprecedented pressure due to climate change. A better understanding of how plants respond to environmental stresses, such as heat waves and droughts, is essential for designing effective mitigation strategies.
The eddy covariance method is now the leading method for measuring greenhouse gas exchanges between ecosystems and the atmosphere. It provides continuous, direct data that is widely used for studies on droughts, atmospheric inversions, satellite validation, etc. The method makes it possible to estimate the carbon sink of soils and plants, resulting from the balance between carbon absorbed by photosynthesis (gross primary productivity, GPP) and carbon emitted by ecosystem respiration (RE).
The future of terrestrial carbon sinks will depend on the evolution of these carbon fluxes. Understanding how photosynthesis and respiration respond to extreme events (heat, drought) is therefore essential to guide the transition to a low-carbon economy and help ecosystems adapt.
We have recently developed a method based on wavelet analysis to estimate ecosystem fluxes even under non-stationary conditions (Destouet et al. 2024). In addition, another study used wavelet analysis to estimate photosynthesis and respiration from the eddy covariance raw data (Coimbra et al. 2023).
Profile: We are seeking a motivated candidate who is eager to work in an interdisciplinary setting at the intersection of signal processing, fluid mechanics, and ecophysiology. They should have strong computer skills, an aptitude for mathematics, have interest in research related to climate change, and an affinity to work with international partners.
Deadline for applications is 14th September 2025.
