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 have not been included in the analysis for the entire period 1996-2007 due to the same reasons. Turkey is not included in the analysis 1996-2008.

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
