Daviz Visualization Concentration status for the target value threshold for protection of human health, 2011
Distribution of stations by thresholds of the 93.15 percentile of the daily maximum of the running 8-h mean O3 concentrations for the year 2011. The chart is based on the 93.15 percentile of the daily maximum of the running 8-h mean O3 concentrations, corresponding to the 26th highest O3 concentration when data availability is 100% over the year.

Figure Agricultural area (in 1 000 km²) in EEA member countries for each exposure class
Due to lack of detailed land cover data and/or rural ozone data Iceland and Norway are not included until 2006 and onwards. Switzerland and Turkey have not been included in the analysis for the entire period 1996-2007 due to the same reasons.

Indicator Assessment Emissions of ozone precursors (CSI 002/APE 008) - Assessment published Jun 2014
Emissions of the main ground-level ozone precursor pollutants have decreased across the EEA-33 region between 1990 and 2011; nitrogen oxides (NO X ) by 44%, non-methane volatile organic compounds (NMVOC) by 57%, carbon monoxide (CO) by 61%, and methane (CH 4 ) by 29%. This decrease has been achieved mainly as a result of the introduction of catalytic converters for vehicles, which has significantly reduced emissions of NO X  and CO from the road transport sector, the main source of ozone precursor emissions. The EU-28 as a whole reported 2011 emissions at 4% below the 2010 NECD ceiling for NO X , one of the two ozone precursors (NO X  and NMVOC) for which emission limits exist under the EU's NEC Directive (NECD). Total NMVOC emissions in the EU-28 were 22% below the 2010 NECD limit in 2011, however, seven of individual Member States did not meet their ceilings for one or both of these two pollutants. Of the three non-EU countries having emission ceilings for 2010 set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland), all reported NMVOC emissions in 2011 that were lower than their respective ceilings, however Liechtenstein and Norway reported 2011 NO X  emissions higher than their ceiling for 2010.

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.

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.
