Concentrations of O₃ in 2023 and 2024 in relation to the EU target value

The maps show the 93.2^th percentile of the O₃ maximum daily eight−hour mean. The 93.2^th percentile represents the 26^th-highest value in a complete series. It is related to the O₃ target value.

Units

µg/m³

Additional information

At sites marked with the last two colour categories, the 26^th highest daily O₃ concentrations were above the 120 μg/m³ threshold, implying values above the target value threshold.
Data are presented here for 1 year instead of the average over a 3-year period, as stated in the definition of the EU target value for O₃.
Only stations with more than 75 % of valid data have been included.
