EMEP Eulerian model for acid deposition over Europe
A 3-D Eulerian acid deposition model has been developed at MSC-W. The model has approximately 50 km horizontal resolution with 20 vertical layers, of which 10 are below 2 km. Meteorological input, from a dedicated weather prediction model, is updated at six-hour intervals. Emission inventories for SO2, NOx (NO + NO2) and NH3, reported officially by individual countries, are used as input data. A brief description of the current model version is given, as well as the model results for sulphur compounds in 1992. We present a comparison of calculated and measured SO2 and SO4 annual (scatter plots) and daily concentrations (time-series) at selected locations in Europe.
