Éclaire

ÉCLAIRE investigates the ways in which climate change alters the threat of air pollution on European land ecosystems including soils. Based on field observations, experimental data and models, it establishes new flux, concentration and dose-response relationships, as a basis to inform future European policies. Starting with biosphere-atmosphere exchange measurements, ÉCLAIRE quantifies how global warming and altered precipitation will affect emissions of key European primary pollutants (NOx, NH3, VOCs), including interactions with increasing aerosol and hemispheric O3 background concentrations, modifying atmospheric transport and deposition. An ensemble of chemistry transport models will be applied to assess uncertainty in response to harmonized scenarios for climate, emissions and land-use, while high resolution studies will investigate how climate change alters local patterns of pollutant exposure and threshold exceedance.
Research activities of INRES focus on the accumulation of hygroscopic particles on leaf surfaces due to increased aerosol deposition and their interactions with plant water relations and plant/atmosphere exchange of trace gases.
