Air Quality (Ozone Pollution)
The data plotted is sent to us approximately one hour after it is collected, between 8am and 8pm, from the Environmental Protection Agency (EPA). The EPA uses its Air Quality Index to provide general information to the public about air quality and associated health effects. An Air Quality Index (AQI) of 100 for any pollutant corresponds to the level needed to violate the federal health standard for that pollutant. For ozone, an AQI of 100 corresponds to 0.08 parts per million (ppm) over an 8-hour period -- the current federal standard. Over half of the U.S. population lives in areas where the AQI exceeds 100 and violates the federal health standard at least once per year.
