Figure Attainment situation for O3, reference years 2010, 2005 and 2001
The graphs are based on the 93.2 percentile of maximum daily 8 hours mean concentration values corresponding to the 26th highest daily maximum of the running 8h-mean; they present the range of concentrations at all station types (in μg/m3) officially reported by the EU Member States and how the concentrations relate to the target value set by EU legislation (marked by the red line). The diagram indicates the lowest and highest observations, the means and the lower and upper quartiles. The lower quartile splits the lowest 25 % of the data and the upper quartile splits the highest 25 % of the data.

Figure Trend in annual mean of daily max 8 h-mean O3 concentrations (left) and trend in 93.2 percentile of daily 8 max h-mean O3 concentrations (right) (in μg/m3) for 2001–2010 per station type
All stations in EU Member States, with at least 75 % data coverage for at least eight years were included in the analysis. Concentrations per station type are given in μg/m3. In the diagrams a geographical bias exists towards central Europe where there is a higher density of stations. The 93.2 percentile of daily max 8-h mean values is directly related to the target value for O3, as 25 days per year are allowed to have exceedances of the target value threshold of 120 μg/m3.

Figure Exposure of forest area to ozone (exposure expressed as AOT40 in (mg/m³).h) in EEA member countries
Please consider that since 2004 a growing number of member countries has been included. In 2004 Bulgaria, Greece, Iceland, Norway, Romania, Switzerland, and Turkey have not been includedwere added. In For 2005/2006 Iceland, Norway Switzerland and Turkey are were still excluded in the analyses due to lack of detailed land cover data and/or rural ozone data. In 2007 Switzerland and Turkey are were not included. Since 2008 only Turkey is has not beennot included. Calculations of forest exposure are not available for year prior to 2004.

Figure Rural concentration map of the ozone indicator AOT40 for forest in 2010
The gradient of the AOT40f values is similar to those of the AOT40c for crops: relative low in northern Europe, and the highest values observed in the countries around the Mediterranean. The critical level is met in north Scandinavia, Ireland, part of the UK and in the coastal regions of the Netherlands (total forested area with concentrations below the critical level is 22 % of a total area of 1.44 million km2). In south Europe levels may be as high as 4-5 times above the critical level.
