Figure 9. Frequency distribution of ozone concentrations (24h values) in excess of the 65 µg/m3 threshold for daily values. For each country the total number of observed exceedances is given in row '#Ex', the number of stations is given in row '#St'. Frequency distributions are presented as Box-Jenkins plots indicating the minimum, the 25-Percentile, the 75-percentile and the maximum value.
