AIRAHEAD

Provenance & coverage

Data sources

The forecast, station, location and health-reference sources used by AirAhead.

Forecast and rankings

Local forecasts and ranking snapshots are requested from Open-Meteo’s Air Quality API, which combines atmospheric datasets including CAMS. AirAhead labels these readings as modelled values.

Live station map

The interactive station layer is provided through the World Air Quality Index project. We proxy requests server-side so credentials are not exposed to the browser. Station coverage varies by area.

Location

Approximate IP lookup uses NetArt endpoints and FreeIPAPI fallback. After a user grants precise-location access, the browser sends the current coordinates directly to BigDataCloud to obtain a readable city name. The selected location is cached locally to avoid repeated lookups.

Health context

General exposure-reduction guidance is informed by public material from the US EPA, WHO and public-health agencies. It is educational context, not individual medical advice.
