14 Long-term health objective summary stats Country OW EEA CDR OW - EEA CDR F-test T-test Diff > 10 % Mean Mean Mean diff.% Stdev. diff. % % of total excee. Austria Belgium Czech Republic France Germany Netherlands

15 Conclusions For the six countries investigated: High degree of match in days with exceedance episodes registered (exception is Czech OW vs. EEA CDR); 2 or more exceedance episodes on one day sometimes account for large numbr of exceedances (40 % for Austria); Time-lag in start of exceedance is constant and there are almost no difference in duration of exceedances; The max concentration during exceedances shows only some small differences (no significant difference in the two datasets); For alert threshold: 100 % match in all countries when comparing EEA CDR with OW. When you get an alert threshold exceedance in EEA CDR you get one in OW
