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.

Figure Exposure of agricultural area to ozone (exposure expressed as AOT40 in (μg/m³).h) in EEA member countries
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

Figure Exposure of agricultural area to ozone (exposure expressed as AOT40 in (μg/m³).h) in EEA member countries
In the Air Quality Directive (2008/50/EC) the target value for protection of vegetation is set to 18 000 (μg/m³).h while the long-term objective is set to 6 000 (μg/m³).h. 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.

Figure Annual variation in the ozone AOT40 value (May-July) in (μg/m³).h, 1996-2007
Average values over all rural stations which reported data over at least nine years in the period 1996-2007. The light blue line corresponds to the 5-year averaged value.

Figure Rural concentration map of the ozone indicator AOT40 for forest in 2009
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).

Figure Rural concentration map of the ozone indicator AOT40 for forest in 2011
The gradient of the accumulated ozone exposure values over a threshold of 40 parts per billion for forests (AOT40f) is similar to that of the AOT40c (crops). AOT40f increases from northern Europe to reach the highest values in the countries around the Mediterranean.
