Development of a source emission model for atmospheric pollutants in the Barcelona area

We describe the EMITEMA-EIM atmospheric emission model, and how it has been used along with CORINAIR emission factors to estimate the annual emissions in the Barcelona area in 1990. The study area is a 39 x 39 km2 square with a high population density and important industrial activities. The space and time resolution of the emissions is, respectively, 1 km2 and 1 h. The pollutants considered were NOx, CO, SO2, particles, methane and several VOCs (alkanes, alkenes, aromatics and aldehydes). The emission sources studied were road traffic, air traffic, industrial activities, gas stations, domestic heating and biogenic emission from forests. Methodologies for each of these sources are described in this paper. Finally, we present and analyse the results.
