✦ Synopsis

An eulerian long-range transport model for the calculation of concentrations of SO2, SO4, NOx, and NO 3 and wet and dry depositions of SOx(sum of SO 2 and SO4) and NOy (sum of NO, NO2 and NO3) over Europe is presented. The model is developed in such a way that only routinely available, analyzed or prognostic meteorological fields are required as input data. In this way it is possible to obtain a forecast of the air quality during smog episodes. For evaluation of smog episodes the model provides a way to estimate the contributions of different sources and the effect of emission scenarios. The model has been evaluated for four winter and three summer episodes. The modeled concentrations of SO2 and SO4 are in agreement with the available measurements. A less good agreement is found for NO2 and NO x (sum of NO and NO2) concentrations. For these components the model tends to underpredict the measured values.
