* The station Prague-Libuš is representative for Prague and Central Bohemia and the station Brno-Tuřany is representative for Brno and South Moravia region. Therefore the total number of stations for the CR is lower than the sum of the numbers of representative stations for individual areas.

Note: The number of days and their share (%) in the period from 1 January to 31 March and from 1 October to 31 December when at least one station representative for the given SVRS area recorded the exceedance of PM10 limit value (daily average 50 µg.m-3), informative threshold value (24-hour concentration 100 µg.m-3) or the regulatory threshold value (24-hour concentration 150 µg.m-3). The maximum values are presented for the stations located in the given SVRS area (i.e. not necessarily all representative stations for the given area are presented).
