The LPC2E is seeking a postdoctoral researcher in the framework of the ASTuS (Ascending Smoke Turbo in the Stratosphere) project funded by the ANR French agency over the period 2022-2025. The objective of the project is to simulate the recently discovered smoke vortices in the stratosphere (Khaykin et al., 2021, Lestrelin et al., 2021) which are generated during extreme fire events. These very intense fires inject a large amount of carbonaceous aerosols into the stratosphere by pyroconvection which then seem to self-organize as heated vortices. A deep understanding of the dynamics of these vortices is still to be achieved. The ASTuS project aims at better understanding the mechanisms controlling these structures through a collaboration between theoretical fluid-mechanic specialists, specialists of stratospheric measurements and atmospheric modelers. The post-doc will work at LPC2E with Dr. Fabrice Jégou and Dr. Gwenaël Berthet in close collaboration with the Laboratoire Inter-Universitaire des Systèmes Atmosphériques (LISA) and Dr. Pasquale Sellitto.


Simulations will be performed with the CESM Earth model (Bossolasco et al., 2021, Tidiga et al. 2022). The post-doc will perform simulations on two realistic case studies during the extreme fires in Canada in 2017 and Australia in 2020. These simulations will be compared with available satellite and in-situ measurements. Simulations will also be performed over the period 2000-2020 to estimate the global impact of such events on climate and stratospheric chemistry, including the implications on the development of mini-ozone holes.


Candidates should have a PhD with robust knowledge in one (or more) of the following scientific topics: fluid mechanics, atmospheric physics, atmospheric chemistry. Experience in the use of global or regional modelling tools is particularly recommended. Knowledge of Linux environment, high performance calculation (HPC), programming (Fortran, Python, IDL) is also required. A good knowledge of English is required.

Work Context

The duration of the position is between 12 and 24 months. The post-doc can start between January and March 2023. Applications should be made via the website https://emploi.cnrs.fr/ or https://euraxess.ec.europa.eu or be sent directly to Fabrice Jégou (fabrice.jegou@cnrs-orleans.fr), Gwenaël Berthet (gwenael.berthet@cnrs-oleans.fr) and Pasquale Sellitto (pasquale.sellitto@lisa.ipsl.fr). The application should include a CV, a description of research experience and how it can benefit the project, and the names and contacts of two academic referees. Applications should be sent before November 10. The work will take place at LPC2E in Orleans (city center is at about one hour by train from Paris). The selected candidate will join the Atmospheric Environment and Planetology team (https://www.lpc2e.cnrs.fr/environnement-atmospherique-et-planetologie). This team is composed of 10 researchers working on aerosols and atmospheric chemistry at different scales ranging from continental surfaces to the middle atmosphere. The team is involved in many projects around volcanic emissions, biomass fires or wetlands.

Constraints and risks

The work will require travel to Paris to work with other members of the project in the different laboratories involved (LISA, LMD, IPGP, LadHyX).
