Figure Ozone - Target value for the protection of vegetation
In the air quality directive (2008/EC/50), the EU has set a target value and a long term objective value for ozone (O3) for the protection of vegetation. Target value: the AOT40 may not exceed 18000 (µg/m3) per hour in the period from 1 May to 31 July averaged over five years. Long term objective value: the AOT40 may not exceed 6000 (µg/m3) per hour in the period from 1 May to 31 July within a calendar year. AOT40 (expressed in (μg/m3) ∙ hours) means the sum of the difference between hourly concentrations greater than 80 μg/m3 (= 40 parts per billion) and 80 μg/m3 over a given period using only the one-hour values measured between 8.00 and 20.00 Central European Time (CET) each day. More information is provided in Annex VII of directive (2008/EC/50).

Figure Annual variation in the ozone AOT40 value for crops (May-July) in (μg/m³).h, 1996–2010
Average values over all rural stations which reported data over at least eleven years in the period 1996-2010. The black line corresponds to the 5-year averaged value. Variations over Europe in observed values is large, eighty percent of the observations falls with the red shaded area.

Figure 26th highest maximum daily 8-hour mean ozone concentration observed at (sub)urban background stations, compliance with the target is assured when this value is below 120 ug/m3, 2001-2011 (EU-27)
Only urban and sub-urban background monitoring stations have been included in the calculations. Data for Cyprus, Greece and Malta is not included due to missing availability of operational urban and sub-urban background monitoring stations in the Urban Audit cities.
