Postdoc, New transient simulations of the last 3Ma and data-model integration, EPOC - Bordeaux, France

Bordeaux, France
2 years PostDoc position
The work will be carried out at the Laboratoire Environnements et Paléoenvironnements Océaniques et Continentaux (EPOC) starting end of 2023 - early 2024 (duration of 2 years).

The PostDoc will be based at the Laboratoire Environnements et Paléoenvironnements Océaniques etContinentaux (EPOC,, University of Bordeaux (, and will be supervised by Thibaut Caley and Thomas Extier in close collaboration with Didier Roche (LSCE, near Paris,
The mechanisms associated with the climatic changes of the past million years are not fully addressed and understood.
Only very few transient simulations with numerical climate models exist and cover this time period (Willeit et al., 2019; Yun et al., 2023).

The main objectives of this 2 years PostDoc will be:

1) To be part of the realization of new long 3 Ma transient simulations with the iLOVECLIM model.
We propose to decipher the respective influence of external (orbital) and internal (greenhouse gases and ice-sheet) forcings on the climatic evolution of this period with the use of multiple transient simulations. In all of these simulations, we will use the atmospheric, oceanic and detailed vegetation (CARAIB) components with annual and monthly outputs. To reduce the total computing time, we will use an acceleration factor of 5 for the orbital parameters, greenhouse gases concentration and ice-sheet forcing.

2) To analyze the results and perform model intercomparison (CLIMBER-2 Willeit et al., 2019; CESM1.2 Yun et al., 2023). Data model comparison with various climate records from different components of the climate system will be realized together with data model integration, for example data assimilation, for specific time periods of interest.
Critical for this purpose, iLOVECLIM explicitly simulates stable water isotopes, and has been shown to reproduce key features of climate and isotopes in present day and paleoclimate observations (Roche, 2013, Roche and Caley, 2013, Caley et al., 2014; Extier et al., 2023).

Other works with the modelled climate outputs could be considered (for example, study the spatiotemporal habitat suitability for hominin species, Timmermann et al., 2022; Ruan et al., 2023) and we encourage the candidates, if they wish so, to make some proposal during the application.
We are looking for a highly motivated PostDoc candidate who strives for original scientific achievements obtained in team work. A successful candidate is required to have some experience in climate modeling or have operating and programming skills in Unix, Fortran, Python. Candidates with background or basic notions of geosciences, paleoclimate, isotope geochemistry and statistics have an advantage.
Good communication (writing and presentation) skills in English, as well as the commitment to collaborate within an interdisciplinary framework are essential, in particular with fellow scientists working on the iLOVECLIM climate model or paleoclimate records.
Interested candidates can contact Thibaut Caley and Thomas Extier to discuss their interest and to provide further guidance on the PostDoc application.
When you contact Mr. Caley and/or Mr. Extier, please include a brief description of your interest and motivation, examples of previous research work, details of two referees, and an up-to-date CV.
