Note:This AQI expresses an immediate condition of air quality and does not necessarily correspond to the quality indices of the EPA and other countries, which for some pollutants report measurement averages of several hours, generally: 24 hours for particulate matter and 8 hours for carbon monoxide.Official agencies' air quality indexes are consistent with their own national air quality standards, while this AQI uses the values of the US Standard as a reference and applies them globally.
