Photochemical pollution level assessment over the UK based on ozone data 1990-2006

Ozone data from the UK automatic monitoring network for 13 rural and 7 urban sites for the April through September season in the years 1990-2006 have been analyzed on the basis of recently introduced photochemical pollution indicators. The indicators predict the urban sites as prone to photochemical pollution although the average ozone concentrations might be lower or the excess times above a threshold value might be higher than in some rural sites. A good correlation, however, exists with the shape of the frequency distribution of ozone concentrations, especially with the frequency of measured very low (close to zero) concentrations. Compared with similar assessment of photochemical pollution in the Central Europe and the Mediterranean (Italian, Croatian, Slovenian) region the present analysis shows that photochemical pollution problems in the UK are significantly less likely.
