Current research
My research is dedicated to the impact of wildfires on atmospheric chemistry: what chemical species emitted? what trends? what impact on atmospheric pollution? at what temporal and spatial scale? what chemical evolution during the transport?
Main tools:
- satellite observations of fire activity, trace gases and aerosols in the atmosphere,
- regional chemistry transport modeling,
- calculation of fire emissions: APIFLAME software,
- simulations of observations based on model outputs: OPTSIM-aerosols.
Recent projects also include work on the impact of heatwaves and dry spells on atmospheric composition and surface air quality.
Ongoing projects
- FIRESAT (PI, CNES, 2024-2026):
- AOS (co-I, CNES, 2024-2026): prepare the future NASA/CNES AOS mission using observing system simulation experiments.
- ESCALAIR (co-I, ADEME AQACIA, 2022-2025): improve the modeling of long-range transport of wildfire plumes
