Introduction
My research areas are air pollution (more precisily, emissions and deposition processes) and extreme weather events (e.g. droughts, heatwaves, wildfires). I am mostly working with regional numerical models, in conjunction with satellite and in-situ observations.

Article
Full-text available
At high concentrations, tropospheric ozone (O3) deteriorates air quality. Weather conditions are key to understanding the variability in O3 concentration, especially during extremes. This publication aims at quantifying the isolated and combined impacts of both extremes on biogenic isoprene (C5H8) emissions, O3 dry deposition, and surface O3 in sou...
Article
Full-text available
Changes in climate during the Roman Warm Period (RWP, 1–250 CE) and Late Antique Little Ice Age (LALIA, 536–660 CE) play a critical role in early societal evolution, but the climate differences between these two periods and the possible causes of the changes remain poorly explored. Here we use the LOch–Vecode-Ecbilt-CLio-agIsM model Large Common Er...
Preprint
Full-text available
At high concentration, tropospheric O3 deteriorates air quality, inducing adverse effects on human and ecosystem health. Meteorological conditions are key to understand the variability of O3 concentration, especially during extreme weather events. They modify the photochemistry activity and the vegetation state. An important source of uncertainties...
Article
Full-text available
Droughts and heatwaves in the Mediterranean can induce plant activity decline and severe wildfires leading to considerable economic, social and environmental damages. This study aims at statistically quantifying the isolated and combined impacts of these extreme events based on a combination of regional land surface-atmosphere modeling and satellit...
Thesis
Full-text available
Droughts and heatwaves are extreme events able to affect both vegetation and atmospheric chemistry, notably through surface-troposphere interactions. The objective of this thesis is to assess their effects on biomass, fire activity and ozone pollution in the western Mediterranean. This study is mainly based on regional numerical models of the land...
Data
Daily indicator of heatwaves and agricultural droughts based on the Percentile Limit Anomalies method (75 and 90), computed from Med-CORDEX simulations using the coupled WRF-ORCHIDEE regional model (RegIPSL).

Article
Full-text available
Between 1970 and 2015 urban population almost doubled worldwide with the fastest growth taking place in developing regions. To aid the understanding of how urbanisation has influenced anthropogenic CO2 and air pollutant emissions across all world regions, we make use of the latest developments of the Emissions Database for Global Atmospheric Resear...
Thesis
Full-text available
MASTER THESIS: The evolution of climate variability during the second millennium of the Common Era is relatively better known than that of the first, which still contains so many uncertainties. New simulations with the LOVECLIM climate model have been carried out including reconstructions of the latest generation of external forcings (suggested by...
