The last two colour categories indicate stations reporting concentrations above the EU indicative annual limit value (20μg/m³) or the EU annual limit value (25μg/m³) for PM_2.5. The first colour category indicates stations reporting values below the WHO AQG level for PM_2.5 (5μg/m³). Only stations with more than 75% of valid data, and more than 13% in the case of fixed random measurements, have been included.
