Observed concentrations of O3 in 2016. The map shows the 93.2 percentile of the O3 maximum daily 8-hour mean, representing the 26th highest value in a complete series. It is related to the O3 target value, allowing 25 exceedances over the 120-μg/m3 threshold. At sites marked with the last two colour categories dots, the 26th highest daily O3 concentration exceeded the 120-μg/m3 threshold, implying an exceedance of the target value threshold. Only stations with more than 75 % of valid data have been included in the map. The French overseas territories´ stations are not shown in the map but can be found at
