Impactos sobre el ozono y depósito de nitrógeno de los cambios en clima y emisiones previstos para 2050

Abstract

In this study, the impacts of projected changes (2000-2050) in climate only and changes in climate plus reductions of anthropogenic emissions of air pollutants and their precursors on ozone (O3) and nitrogen (N) deposition were estimated using the CHIMERE air quality model for the Iberian Peninsula and Balearic Islands. The results suggest that changes in climate only will increase AOT40 (indicator for impacts of O3 on vegetation), representing a climate penalty, but decrease N deposition. The combination of changes in climate and emissions is expected to reduce the impacts of both O3 and N deposition, with the emission reductions of O3 precursors cancelling out the climate penalty for AOT40.
