in Germany

(Federal Environmental Agency in Germany,

Statement:
The weekend effect with higher values at the weekend is quite clear
for the urban station (figure 1 + 2).
But it arises also for the other station classes. The effect is only less
noticeable in the ranking of traffic stations to rural stations. The effect is
least at the remote (in Germany mountain) stations (figure 5).
It both the averages values and the daily maxima (figure 3) we allocated.
Since, however ozone peak values arise only in certain weather
conditions, we undertook these analyses after 10 objectively defined
weather conditions. The result was confirmed for these weather conditions
(classes, mostly 8,9) where higher ozone concentrations (figure 5)
occured.
Missing:
We analysed only nation wide averages in Germany.
We did not analyse regions to find out differences for luv and lee effects
of conurbation areas.
