Exposure of agricultural area to ozone (exposure expressed as AOT40 in (μg/m3).hour) in EEA member countries . In the Air Quality Directive (2008/50/EC) the target value for protection of vegetation is set to 18000 (μg/m3).h while the long-term objective is set to 6000 (μg/m3).hour. Until 2006 Iceland, Norway Switzerland and Turkey have not been included in the analyses due to lack of detailed land cover data and/or rural ozone data, in 2007 Switzerland and Turkey are not included; since 2008 only Turkey is not included
