* For some SWRS areas also the stations located outside the respective area are representative. Therefore the total number of stations for the CR is lower than the sum of the numbers of representative stations for individual areas. The number of days and their share (%) in the period from 1 January to 31 December 2014 when at least one station representative for the given SWRS area recorded the exceedance of O₃ limit value (daily maximum of the 8-hour running average 120 µg.m^-3), informative threshold value (1-hour concentration 180 µg.m^-3) or the alert threshold value (1-hour concentration 240 µg.m^-3). The maximum values are presented for the stations located in the given SWRS area (i.e. not necessarily all representative stations for the given area are presented).
