Job description
The Laboratoire des Sciences du Climat et de l’Environnement (LSCE) is part of the CLIMPEAT ERC Synergy project funded by the European Commission. We are looking for a post-doctoral fellow for modelling the response of non-CO2 greenhouse gases, including abrupt changes
Laboratoire des Sciences du Climat et de l’Environnement (LSCE)
Is a world-class research laboratory established and a collaboration between CEA, CNRS and the University of Versailles Saint-Quentin (UVSQ) https://www.lsce.ipsl.fr. It is part of the Institute Pierre Simon Laplace (IPSL). LSCE hosts approximately 300 researchers, engineers and administrative staff including many PhD and master’s students. This project will provide the employee with the opportunity to work directly on advanced methods with researchers from the LSCE and other institutions. We offer a stimulating and friendly environment in a diverse and international institution with research and education at a very high level.
Project description
Northern peatlands store large amounts of carbon and have been projected to shift from a net sink of greenhouse gases to a net source under global warming. As a Postdoctoral Fellow in this project you will work with the ORCHIDEE PEAT land surface model to predict the response of northern peat to climate change including abrupt changes and thermokarst disturbances. The research contributes to the Northern Peatlands in the face of climate warming and abrupt changes (CLIMPEAT) ERC Synergy project funded by the European Research Council. You will work in a dynamic international research environment with many possibilities for international collaboration and exchange. The work may include fieldwork in remote permafrost regions.
Main responsibilities
Develop the ORCHIDEE PEAT1,2 model developed at LSCE with international partners and dedicated to the biogeochemistry of peatlands, to improve the representation of CH4 production, diffusion, ebullition, plant transport processes in the soil profile and predict CH4 emissions from field sites to globe for past, present and future climate conditions, with a special focus on the response of CH4 emissions after abrupt changes and thermokarst processes. New processes incorporated in the model include an advanced representation of soil microbial activity and adaptation, water table dynamics at high resolution, and permafrost ground ice collapse. In a second step, N2O emissions processes in permafrost peat and organic soils may be included from recent theoretical developments and experimental studies.
Qualification Requirements
In order to qualify for a Postdoctoral position, applicants are required to hold a doctoral degree. The degree must have been completed no later than when the employment decision is made.
Assessment criteria
- Programming skills, preferably in Python, Fortran
- Understanding and experience of ecosystem models and earth system models
- Development of scripts for processing of large amounts of geographical data
- Autonomy, ability to work in a team and time management skills.
- Experienced in multidisciplinary team-based activities with the ability to effectively communicate
Contract duration
24 months with a possible extension
Starting date
The position is available until July 10 2026 and will remain open until filled. The expected start of the position is October 2026.
Salary
Competitive salary, full social & health benefits, commensurate with work experience.
