The map is based on time series of PM10 mass concentration at over 360 government monitoring stations in Slovakia, the Czech Republic, Austria, Poland and Germany. Labelled frontal lines indicate where the peak values of PM10 occurred simultaneously. The peak PM10 concentration is coded in color. Credit Source: W. Birmili et al, Atmos. Chem.
