Clustering of atmospheric and emission conditions that lead to modelled peak ozone concentrations

An application of a simple urban air quality model (DAUMOD-GRS) shows that summer maximum O3 hourly concentrations (Cmax) above 40 ppb occur outside the Metropolitan Area of Buenos Aires (MABA) where the absence of observations impedes model testing. In addition, those relatively high values present...
