Figure Exposure of forest area to ozone (exposure expressed as AOT40 in (μg/m³).h) in EEA member countries
The figure shows the exposure of forest area to ozone (exposure expressed as AOT40f in (μg/m3).h) in EEA member countries . By the UNECE a critical level for protection of forest is set to 10000 (μg/m3).hour. Since 2004 a growing number of EEA member countries have been included. In 2004 Bulgaria, Greece, Iceland, Norway, Romania, Switzerland, and Turkey have not been included. In 2005-2006 Iceland, Norway Switzerland and Turkey are still excluded 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. Calculations of forest exposure are not available for year prior to 2004.
