90.4 percentile of PM10 daily concentrations in 2019

Observed concentrations of PM10 in 2019. The data presented were reported as up-to-date (UTD) data and therefore should be considered as not validated. They are used for the purpose of providing a preliminary assessment of the situation in 2019 in relation to the PM10 daily limit value. Furthermore, the possibility of subtracting contributions to the measured concentrations from natural sources and winter road sanding/salting has not been considered. The map shows the 90.4 percentile of the PM10 daily mean concentrations, representing the 36th highest value in a complete series. It is related to the PM10 daily limit value, allowing 35 exceedances of the 50 μg/m3 threshold over 1 year. Triangles in the last two colour categories indicate stations with concentrations above this daily limit value. Only stations with more than 75 % of valid UTD data have been included in the map.
