The first (CLE) scenario reflects implementation of current air quality legislation around the world, while the second (MFR) represents a more optimistic case in which all currently feasible technologies are applied to achieve maximum emission reductions. We contrast these scenarios with the more pessimistic IPCC SRES A2 scenario. Ensemble simulations for the year 2000 are consistent among models and show a reasonable agreement with surface ozone, wet deposition, and NO2 satellite observations. Large parts of the world are currently exposed to high ozone concentrations and high deposition of nitrogen to ecosystems. By 2030, global surface ozone is calculated to increase globally by 1.5 +/- 1.2 ppb (CLE) and 4.3 +/- 2.2 ppb (A2), using the ensemble mean model results and associated +/- 1 sigma standard deviations. Only the progressive MFR scenario will reduce ozone, by -2.3 +/- 1.1 ppb. Climate change is expected to modify surface ozone by -0.8 +/- 0.6 ppb, with larger decreases over sea than over land. Radiative forcing by ozone increases by 63 +/- 15 and 155 +/- 37 mW m(-2) for CLE and A2, respectively, and decreases by -45 +/- 15 mW m(-2) for MFR. We compute that at present 10.1% of the global natural terrestrial ecosystems are exposed to nitrogen deposition above a critical load of 1 g N m(-2) yr(-1). These percentages increase by 2030 to 15.8% (CLE), 10.5% (MFR), and 25% (A2). This study shows the importance of enforcing current worldwide air quality legislation and the major benefits of going further. Nonattainment of these air quality policy objectives, such as expressed by the SRES-A2 scenario, would further degrade the global atmospheric environment. 000054104 536__ $$0G:(DE-Juel1)FUEK406$$2G:(DE-HGF)$$aAtmosphäre und Klima$$cP22$$x0 000054104 588__ $$aDataset connected to Web of Science 000054104 650_7 $$2WoSType$$aJ 000054104 7001_ $$0P:(DE-HGF)0$$aStevenson, D.$$b1 000054104 7001_ $$0P:(DE-HGF)0$$aEllingsen, K.$$b2 000054104 7001_ $$0P:(DE-HGF)0$$avan Noije, T.$$b3 000054104 7001_ $$0P:(DE-Juel1)6952$$aSchultz, M.$$b4$$uFZJ 000054104 7001_ $$0P:(DE-HGF)0$$aAmann, M.$$b5 000054104 7001_ $$0P:(DE-HGF)0$$aAtherton, C.$$b6 000054104 7001_ $$0P:(DE-HGF)0$$aBell, N.$$b7 000054104 7001_ $$0P:(DE-HGF)0$$aBergmann, D.$$b8 000054104 7001_ $$0P:(DE-HGF)0$$aBey, I.$$b9 000054104 7001_ $$0P:(DE-HGF)0$$aBouwman, L.$$b10 000054104 7001_ $$0P:(DE-HGF)0$$aButler, T.$$b11 000054104 7001_ $$0P:(DE-HGF)0$$aCofala, J.$$b12 000054104 7001_ $$0P:(DE-HGF)0$$aCollins, B.$$b13 000054104 7001_ $$0P:(DE-HGF)0$$aDrevet, J.$$b14 000054104 7001_ $$0P:(DE-HGF)0$$aDoherty, R.$$b15 000054104 7001_ $$0P:(DE-HGF)0$$aEickhout, B.$$b16 000054104 7001_ $$0P:(DE-Juel1)VDB64819$$aEskes, H.
