Frequently Asked Questions
What is AQI?+
Air Quality Index — a 0-500+ scale measuring air pollution; higher = worse. 0-50 is good, 301+ is hazardous.
Why might results fail?+
The location doesn't exist, or the air quality API is temporarily unavailable. Try a more specific city name.
How often is data updated?+
Typically every 1-3 hours depending on the monitoring station network in your region.
What do the pollutants mean?+
PM2.5/PM10 = particulate matter; O3 = ozone; NO2 = nitrogen dioxide; SO2 = sulfur dioxide. Higher = worse.
Is this real-time?+
Yes, sourced from open-meteo API which aggregates global monitoring networks.
