Observed concentrations of PM2.5 in 2015. The map shows the PM2.5 annual mean concentrations. The red and dark-red dots indicate stations with concentrations exceeding the limit value (25 μg/m3). The dark green dots indicate stations reporting values below the WHO air quality guidance for PM2.5 (10 μg/m3). Only stations with more than 75 % of valid data have been included in the map.
