Spatial distribution of SO_2 in the Athens basin

摘要

This study is an attempt to examine the influence of the wind field on SO_2 levels in the greater Athens basin. The CTDM model, improved by the incorporation of the PAL 2.0 algorithm, was applied in the examined area. A satisfactory agreement between the measured and estimated SO_2 values was observed at the time the maximum values appeared but the model overestimated these maxima whereas, the rest of the hours it gave lower concentrations than the recorded values.
