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.

Additional information
- AOT40 (crops)
(Accumulated dose of ozone Over a Threshold of 40 ppb)
AOT40 means the sum of the differences between hourly concentrations greater than 80 µg/m3 (= 40 parts per billion) and 80 µg/m3
