About this data
Readings are hourly Air Quality Index values from official monitoring stations run by state, local and tribal air agencies, distributed by the U.S. EPA AirNow program. We check for new readings every 15 minutes and show each station's value for PM2.5, PM10 and ozone as reported, without averaging or adjustment. The data is preliminary and not validated: agencies may change readings after quality checks, so it is not used here for trends or long-term comparisons. For official forecasts and the latest readings, see AirNow.gov. AQI categories and colors are the EPA's.
