TitleFunded Ph.D position in modelling micrometeorology
CategoryPhD Studentship
LocationFrance, Bordeaux
InternationalYes, international applications are welcome
Closure DateWednesday, June 01, 2022
A PhD position is open at the ISPA laboratory at INRAE Bordeaux (France) on the impacts of spatial landscape heterogeneities on microclimate in the framework of the MaCCMic project.

Context – objectives - method
The heterogeneity of agricultural-forestry landscapes generates strong spatial variations in micrometeorological fields (wind, temperature, humidity), with potentially areas where climatic extremes (drought, heat wave, storm) are mitigated, protecting plants and biodiversity. In a context of increasing extreme events, it is crucial to better understand the role played by these structural heterogeneities on the microclimate in order to mitigate climate extremes. Due to the difficulty of obtaining a complete and detailed spatial representation of the micrometeorology at landscape scale from field measurements, it is necessary to combine them with numerical simulations at this scale. Importantly, simulations make it possible to evaluate management scenarios and to identify the role of each factor independently of the others.

The goal of this PhD is to simulate turbulent micrometeorology at agricultural-forestry landscape scale and to determine the potential contribution of different structural heterogeneities of the landscape to mitigate climate extremes. The originality here is to simulate the turbulent character of micrometeorological fields in order to understand the exchange mechanisms and interactions between spatial scales generated by the landscape heterogeneities.

To do so, this PhD will rely on an innovative modelling approach based on the coupling between (1) a meteorological model adapted to fine spatial scales and explicitly simulating turbulent structures, and (2) a multi-layer model estimating mass (water, CO2) and energy fluxes in forest and agricultural canopies. Combined with in situ experiments, this innovative modeling approach will allow (1) to understand the role played by landscape heterogeneities (edges, slopes, hedges, riparian forests) on the variability of micrometeorological fields, and (2) to study scenarios of agricultural-forest landscape management in order to mitigate climatic extremes (plot size, riparian forest widths...).

This PhD is part of the more general framework of the ANR project MaCCMic (Impact of forest Management and Climate Change on understory Microclimate) (2022-2026). This project aims to develop tools to identify the main factors influencing understory microclimate and to anticipate the impact of forest management (density, fragmentation, plot size, riparian width, etc.) and climate change on forest microclimate and understory vegetation, particularly in terms of climatic extremes.

Expected profile
- Master or engineer in fluid mechanics, atmospheric physics, or geophysics with an interest in modelling
- Good experience in programming under Linux environment
- Excellent writing skills, fluent in English
- Rigorous, autonomous, creative and motivated by working in a research environment

Supervision and working conditions
The PhD student will be co-supervised by Sylvain Dupont (Research Director at INRAE), Mark Irvine (Research Engineer at INRAE), and Jérôme Ogée (Research Director at INRAE) and will be integrated within the Physics at the Ecosystems Interface (YSYS) team of the ISPA lab and within the lab consortium of the MaCCMic project. The student will benefit from the scientific and methodology experience of the team and consortium. He (or she) will have access to the ISPA’s computational resources and to the clusters of IDRIS and CEA. Finally, he (or she) will benefit from the national and international collaborations established by the team and consortium.

The PhD student will be based at the Interactions Sol-Plant-Atmosphere (ISPA) lab in Bordeaux (France). This lab offers an excellent scientific environment; it is member of the Idex of Bordeaux University. The lab is located at INRAE campus, within a few minutes from downtown Bordeaux. The PhD student will be registered at the “Sciences and Environment” doctoral school of the University of Bordeaux.

The PhD student will be offered a three years contract with INRAE. The gross salary will be 1870 € (including social security for illness, maternity and unemployment, as well as financial help for public transportation and canteen). The PhD is expected to start by Fall 2022.

How to apply?
Any Master student interested in this project is required to send his/her CV and a motivation letter to Sylvain Dupont ( at before June 1st 2022.
