Concentrations per station type are given in μg/m3. In the diagram a geographical bias exists towards central Europe where there is a higher density of stations.

The diagram indicates the lowest and highest observations, the means and the lower and upper quartiles. The lower quartile splits the lowest 25 % of the data and the upper quartile splits the highest 25 % of the data.
