Sources & scope
AirNow Current Monitor Data Public, published through EPA's ArcGIS service; agency credit appears beside each monitor. Values are provisional, subject to revision and intended for AQI reporting, not regulatory decisions or long-term trend analysis. Concentrations and reported AQI can use different averaging periods; AQI is not recalculated from the concentration shown.
County membership is a spatial comparison against official NWS county-zone polygons, not a countywide average. No monitor in a county does not mean safe air. A reported zero is preserved; missing readings stay unavailable.
