Figure 2. Frequency distribution of ozone concentrations (eight-hourly values; period 12.00-20.00) in excess of the 110 µg/m3 threshold for hourly 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. The data for Portugal did not allow for inclusion in this figure.
