Number of days with daily highest

info:
The number of days with daily highest 8-hour mean ozone concentrations higher then 120 µg/m3 are published in the table below.
According to EC directive 2002/3/EC the target value for the protection of human health, is the daily highest 8-hour ozone concentration that cannot be exceeded more then 25 times days per calender year averaged over three years. The averages over three years are published in the yellow table cells. The orange table cells indicate a value higher then 25.
Besides the averages over three years the number of exceedances is also published per calender year. 2010 will be the first year to calculate compliance with the directive.
The long-term objective for the protection of human health, is no more exceedances of the daily highest 8-hour mean of 120 µg/m3.
This table will be updated every day at around 07:00 AM.
