Summary of Exceedances
Only three one-hour exceedances of fine particulate matter (PM2.5) were recorded, with no exceedances of any 24-hour objectives in the quarter. These brief events were linked to a wintertime temperature inversion and localized sources.
Air quality measurements are compared continuously to both one and 24-hour AAAQOs. An exceedance of an AAAQO is reported to the Alberta Government, and the likely cause of the exceedance is investigated.
