  • Days with Exceedences
    The number of days with exceedences is the number of days on which at least one period has a concentration greater than, or equal to, the relevant air quality standard (the averaging period will be that defined by that Standard). Since the National Air Quality Standards cover different time periods (15 min average, 24 hour running mean etc.), this gives a useful way of comparing data for different pollutants.
