Assessment of the Effects of the Spanish National Air Pollution Control Programme on Air Quality

During the last few decades, European legislation has driven progress in reducing air pollution Europe through emission mitigation measures. In this paper, we use a chemistry transport model to assess impact on ambient quality of measures considered for 2030 scenarios with existing (WEM2030) and additional (WAM2030). The study estimates general improvement WAM2030 scenario, no non-compliant zones NO2, SO2, PM indicators. Despite an O3, still areas. For pollutant, scenario leads different impacts depending indicator considered. Although reduction maximum hourly O3 concentrations, small increases concentrations winter nighttime summer lead annual mean some areas other indicators (SOMO35 health AOT40 vegetation) urban results suggest that lower NOx emissions WEM WAM less removal by NO titration, especially background ozone both locally produced summer, high emissions.
