Abstract

Ozone data from 13 rural and 11 urban sites for the growth season (April through September) during 1990-2006 have been analysed on the basis of recently introduced photochemical pollution indica-tors. The indicators predict that urban sites are prone to photochemical pollution, although compared to some rural sites, the urban sites have lower average ozone concentrations and showed lower values of time for which hourly average ozone concentration is above a threshold value. Interestingly, the frequency distribution of ozone concentrations, especially the frequency of very low (close to zero) concentrations, correlates well with the average ozone volume fraction during the growth period. The present analysis shows that photochemical pollution in the UK is less severe compared with photochemical pollution in central Europe and the Mediterranean region (Italy, Croatia, Slovenia).
