This postdoctoral position will be open at LPC2E (CNRS, Orléans University, CNES, https://www.lpc2e.cnrs.fr/en/) in Orleans, France. It will contribute to better understand peatland greenhouse gases (GHG), volatile organic compounds (VOC) and biomass burning emissions in the context of climate change.

Within this thematic, different focus and approaches are possible:

- Data collection and analysis. We will use data gathered from monitored natural sites belonging to national and international networks (e.g. SNO-Tourbières) and from satellites missions (e.g. SMOS, Landsat, Sentinel) ensuring data integration on a global scale. The analysis will focus on the interaction between biotic (vegetation, microbial activity) and abiotic (meteorological and hydrological parameters) drivers of peatland emissions to better understand their heterogeneity and climate sensitivity. Studies on mesocosms could complement the natural site observations.

- Representation of peatland emissions in land surface model. Modelling the peatland fluxes will be achieved using the established model ORCHIDEE. This model will be develop to improve our understanding of the interaction of the peatlands with the climate. Focus will be put on improving the representation of processes responsible for peatland emissions. Knowledge gained from peatland functioning under the drive of global warming will be useful in particular for the evaluation of biomass burning, which affects intensively each year Siberian peats. The model ability to reproduce the observed emission changes due to intensive dryness could be tested. Quantification of emissions at regional and global scales could be also performed.

Applicants with significant experience in 1) data (and isotopic signature) analysis of GHG/VOC measurements from eddy-covariance and chamber instruments and/or 2) continental surface model experiments (either at global or regional scales) and/or 3) space data analysis (e.g. creation of new products) are particularly appreciated.

This call forms part of the WP2 of the second phase of the VOLTAIRE LabEx (called VOLTAIRE2) extending from 2020 to 2024 (see the description of the workpackages at https://labex-voltaire.prod.lamp.cnrs.fr/project-voltaire-2/). Several postdoc positions should be available for the VOLTAIRE2 general atmospheric science topics (i.e. encompassing WP2 and WP3) but the number of final postdoc recruitments will depend on the quality of the applications. The executive committee of the labex will make the selection procedure based on previous achievements of candidates, and compatibility of proposed projects with labex’s topics.

The details of labex organisation and scientific activities can be found at:

http://labex-voltaire.prod. lamp.cnrs.fr/home-page/



Along with their CV and track record, candidates should propose a research project (4 pages) which includes the methodology(ies) they want to implement. They should also provide names of scientists for reference. Projects are expected to use the various experimental and analytical facilities hosted by the laboratory partners and address one of the scientific issues listed above. Positions are for 1+1 year, and depending on results, can be prolonged (expected to lead to CNRS or University permanent positions).

In addition to salary (fixed according to candidate’s experience and French’s rules), the LabEx will provide funding to carry out research activities (laboratory expenses, participation to meetings, etc..).

Applicants are invited to contact Prof. Christophe Guimbaud (christophe.guimbaud@cnrs-orleans.fr; GHG peatland observations), Dr. Fabrice Jégou (fabrice.jegou@cnrs-orleans.fr; satellite observations and chemistry-transport modelling), Line Jourdain (line.jourdain@cnrs-orleans.fr; peatland emissions modelling) ; Sébastien Gogo (sebastien.gogo@cnrs-orleans.fr; GHG peatland observations), with whom the recruited postdoc researcher(s) will collaborate, if they look for more details about the science conducted at LPC2E and ISTO and fitting with this postdoc call.

Applications should be sent to Bruno Scaillet, head of the VOLTAIRE2 LabEx (bruno.scaillet@cnrs-orleans.fr) before the end of September 2020. The selection of candidates will take place in two stages. Firstly, a selection will be made on the quality of the scientific project sent and secondly the selected candidates will be auditioned for a final decision. The ideal start of the postdoctoral position is planned for January 2021.
