FAQ

Where does Airwareness get its air quality data?

Airwareness aggregates air quality data from public and commercial providers (where available for your location). The specific provider may vary by country, region, and pollutant coverage.

Primary data sources used

• Open‑Meteo — Air Quality API: https://www.open-meteo.com/
• OpenStreetMap (Nominatim) — Geocoding: https://www.openstreetmap.org/
• NASA FIRMS — Fire Information for Resource Management System: https://firms.modaps.eosdis.nasa.gov/

Health comparison reference (PM2.5 ↔ cigarettes)

• Berkeley Earth: https://berkeleyearth.org/air-pollution-and-cigarette-equivalence

What do the numbers mean (AQI, PM2.5, PM10, NO₂, O₃)?

• AQI is an index that summarizes overall air quality.
• PM2.5 / PM10 are fine and coarse particles that can affect breathing.
• NO₂ (nitrogen dioxide) often relates to traffic and combustion.
• O₃ (ozone) forms in sunlight and can irritate lungs.

Why does my AQI look different from another app or website?

Differences can happen because of:

• Different data sources and station coverage
• Different update frequency and smoothing
