Long-range transport Lagrangian one-layer model sulphur dioxide

Sažetak
The daily mean concentrations of SO2 have been estimated using a simple trajectory model of long-range transport. Seasonal variations in the transformation rate of SO2 to sulphate are assumed. The mixing height varied from day to day depending on the stability conditions. The dry deposition velocity above the ground varies according to the season, cloud cover and time of day, while a constant value is applied above the sea. Under present model assumptions the variation of pollutant concentration with time at the receptor point arises only due to variable meteorological conditions. During the test period measured concentrations were often higher than estimated. However, the order of magnitude of pollutant concentration was well predicted. In future work, input meteorological data should have a finer resolution. Further, better parameterizations of sulphur dioxide concentrations at the start points of trajectories and wet deposition should be employed.
