As part of the Holisoils project we are offering a 12 month Post Doctoral contract. The main scientific objectives and the related tasks of the position will be to incorporate recent peatland model into the trunk version of the ORCHIDEE land surface model. A peat version of the ORCHIDEE model already exist but it has not been integrated so far in the trunk version used to run the model in an Earth system configuration (i.e. fully coupled with the atmosphere and the ocean). The post doc will have to perform this merge, evaluate the new version of the model against observations and run the new version of the model coupled with the atmosphere following recently published SSP scenarios


The main activities of the candidate will be as follows:
- Implementation of these new peatland equations into the trunk version or ORCHIDEE,
- Its evaluation
- Establishment of a balancing protocol adapted to this new formulation.


- Thesis in climate sciences, bio-geochemistry or soil sciences with a strong attraction for modeling.
- Fortran skills required.
- The candidate must have demonstrated his or her ability to communicate these results in scientific journals and international congresses.

Work Context

Knowledge gaps on global carbon cycle and its feedbacks with the atmosphere limit our capacity to predict the climate change. One key aspect is particularly poorly constrained the role of peatlands in the carbon exchange between the land and the atmosphere. Peatland is a huge reservoir of organic carbon and how its dynamic will evolve in the future may impact drastically the greenhouse gases concentration. It is urgently necessary to develop a better understanding of the peatland processes and a harmonised approach to integrate data into computational models that are used for decision making in order to meet climate and sustainability goals, including the UN's Agenda 2030 SDGs, the Paris Agreement of Climate Convention, the EU Bio-economy Strategy, the EU's LULUCF Regulation, the EU Forest Strategy (2018), and the European Green Deal. The work will be carried out within the framework of the EU-funded Holisoil project led by the LUKE laboratory in Finland.The modeling aspects are the responsibility of IPSL and the work will be supervised by a CNRS researcher with strong interactions with the project partners, particularly in the Netherlands and Spain.
