2 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.

3 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.

4 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 CO 2, 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 O 3 and N impacts on plants and soils, when considering state-of-the-art understanding of interactions with CO 2 and climate, and the different effects of wet vs. dry deposition on physiological responses?

5 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?

20 Preliminary results First results indicate that climate change will worsen the threat of air pollutants on Europes ecosystems: Climate warming may cause an increase the emissions of many trace gases, such as biogenic volatile organic compounds (BVOCs), ammonia (NH 3 ) and the soil component of nitrogen oxides (NO x ) emissions. These effects are expected to increase ground-level concentrations of NH 3, NO x and ozone (O 3 ), 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, O 3, N and aerosol exposure. Further evidence is required before clear statements can be made
