Louisville Metro KY - Local Air Quality API

API operated by Louisville Metro that returns AQI information from local sensors operated by APCD. Shows the latest hourly data in a JSON feed.

The Air Quality Index (AQI) is an easy way to tell you about air quality without having to know a lot of technical details. The “Metropolitan Air Quality Index” shows the AQI from the monitor in Kentuckiana that is currently detecting the highest level of air pollution. See: https://louisvilleky.gov/government/air-pollution-control-district/servi...

See the air quality map (Louisville Air Watch) for more details: airqualitymap.louisvilleky.gov/#

Air Quality Forecast via AirNow

AQI Level - Value and Related Health Concerns Legend

Good 0-50 Green
Air quality is considered satisfactory, and air pollution poses little or no risk.

Moderate 51-100 Yellow
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.

Unhealthy for Sensitive Groups 101-150 Orange
Members of sensitive groups may experience health effects. The general public is not likely to be affected.

Unhealthy 151-200 Red
Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.

Very Unhealthy 201-300 Purple
Health alert: everyone may experience more serious health effects.

Hazardous > 300 Dark Purple
Health warnings of emergency conditions. The entire population is more likely to be affected.

Here are citizen actions APCD recommends on air quality alert days, that is, days when the forecast is for the air quality to reach or exceed the “unhealthy for sensitive groups” (orange) level:

• Don’t idle your car. (Recommended all the time; see the second link below.)
• Put off mowing grass with a gas mower until the alert ends.
• “Refuel when it’s cool” (pump gasoline only in the evening or night).
• Avoid driving if possible. Share rides or take TARC.
• Check on neighbors with breathing problems.
