What is ÉCLAIRE about?
ÉCLAIRE is targeting climate-ecosystem-atmosphere interactions and their implications for ecosystem effects at the European scale, combining observations and experiments in the field and laboratory with modelling experiments from plot to European scales, while accounting for changes in global background.
Overall Project Objectives
Focusing especially on the role of ozone and nitrogen, and (where relevant) their interactions with volatile organic compounds, aerosols and sulphur, ÉCLAIRE aims:
O 1. to provide robust understanding of air pollution impacts on European land ecosystems including soils under changing climate conditions, and
O 2. to provide reliable and innovative risk assessment methodologies for these ecosystem impacts of air pollution, including the economic implications, to support EU policy.
Key questions
• What are the expected impacts on ecosystems due to changing ozone and N-deposition under a range of climate change scenarios, taking into consideration the associated changes in atmospheric CO2, aerosol and acidification?
• Which of these effects off-set and which aggravate each other, and how do the mitigation and adaptation measures recommended under climate change relate to those currently being recommended to meet air pollution effects targets?
• What are the relative effects of long-range global and continental atmospheric transport vs. regional and local transport on ecosystems in a changing climate?
• What are the appropriate metrics to assess O3 and N impacts on plants and
soils, when considering state-of-the-art understanding of interactions with CO2 and climate, and the different effects of wet vs. dry deposition on physiological responses?
Key questions (continued)
• What is the relative contribution of climate dependence in biogenic emissions and deposition vs. climate dependence of ecosystem thresholds and responses in determining the overall effect of climate change on air pollution impacts?
• Which mitigation and/or adaptation measures are required to reduce the damage to “acceptable” levels to protect carbon stocks and ecosystem functioning? How do the costs associated with the emission abatement compare with the economic benefits of reduced damage?
• How can effective and cost-efficient policies on emission abatement be devised in the future?

Figure S5: Estimated relative change in projected anthropogenic NH3 emissions over the period 2008 to 2100, based on Lamarque et al. (2010). These estimates are developed for the Representative Concentration Pathways (RCP) for use by the Intergovernmental Panel on Climate Change according to different warming scenarios of 2.6, 4.5, 6.0 and 8.5 W m-2. The additional effect of the estimated climate feedback on anthropogenic NH3 emissions is illustrated for RCP 8.5 according to a 5 ºC warming by 2100 based on Table S2.

Selected achievements
• Integrated dataset on in-canopy chemistry • Dataset for validation of IASI EO products• Growing database on flux measurements for process
parameterisations across 9-site network• Direct emissions of isoprene oxidation products• Identification of litter as major NO source• Effects of multiple drivers (composition × climate)• Scenarios of N usage and emissions
• Quantification of effect of temperature on NH3 emissions
Preliminary results
First results indicate that climate change will worsen the threat of air pollutants on Europe’s ecosystems:
• Climate warming may cause an increase the emissions of many trace gases, such as biogenic volatile organic compounds (BVOCs), ammonia (NH3) and the soil component of nitrogen oxides (NOx) emissions. These effects are expected to increase ground-level concentrations of NH3, NOx and ozone (O3), as well as atmospheric nitrogen deposition. The emerging message is that this interaction is likely to be significant
• Climate warming may increase the vulnerability of ecosystems towards air pollutant exposure or atmospheric deposition. Such effects may occur as a consequence of combined perturbation, as well as through specific interactions, such as between drought, O3, N and aerosol exposure. Further evidence is required before clear statements can be made
