Abstract: The Po valley is one of the most polluted area in Europe regarding ozone and PM10. To support policy-makers to implement programmes to reduce air pollution, the Veneto Region Environmental Protection Agency has set a state-of-the-art modelling system. Comparison between model results and measurements illustrates a fairly good agreement for NO₂ annual mean concentration and deposition levels and daily maximum O₃ levels. The disagreement for PM10 results suggests the need of further improvements in the emission inventory and the meteorogical pre-processing. The aim of this application is to estimate atmospheric loads on the Venice lagoon through the model|s deposition computation.
