Air Quality Site Reports Daily Air Quality

AIRNow is a daily update of the Air Quality Index (AQI) reporting how clean or polluted the air is in your neighborhood. Five major air pollutants (ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide) are used by the EPA to calculate the AQI.

Using this information, the AIRNow website offers daily AQI forecasts and real-time conditions for over 300 metropolitan areas in the United States. The user-friendly website is a government-backed program, developed collaboratively by the EPA, NOAA, NPS, tribal, state, and local news agencies to assist the public in understanding the health effects of breathing polluted air.
