High spatial resolution effect on ozone pollution modelling: Case study of Agadir city (Morocco)

Abstract The degradation cost of air pollution is estimated to be 1.62 percent of Morocco's Gross Domestic Product. Several studies focused on the high-resolution spatial modeling effect. As a result, in this study, we investigated the CHIMERE model performances in Agadir city using two resolutions, C1(0.1°=11 km) and C3 (0.02°=2 km). The numerical results are compared to ozone monitoring data for spring/summer 2010. The results show that the statistical performance improves for the C3, which improves the model's ozone forecasting. Given the seasonal performance differences, future efforts should concentrate on upgrading the quality of input data to provide more accurate information.
