Database Specific
Database Specific Abstract AbstractThe concentration of O3 at the 99th percentile, for each monitoring station with population representation for gases (EMRPG). The concentration values (ppbv or µg/m3N), based on a calendar year of measurement, will be noted on a list established in increasing order that includes the accumulated concentration at 99%. The primary air quality standard for ozone as an 8-hour concentration will be considered exceeded when the arithmetic average of three successive years of the 99th percentile of the daily maximum concentration of 8 hours recorded during a calendar year in any EMRPG monitoring station is greater than or equal to 61 (ppbv).
