Where this number comes from

The Copernicus Atmosphere Monitoring Service (CAMS) forecasts air pollution worldwide on a grid (about 11 km over Europe, about 45 km elsewhere). We take the grid value at Kaduna’s coordinates and score it with the US EPA’s method. It is a model, not a measurement: a nearby monitoring station can read quite differently, especially next to busy roads or during fires and dust storms.

Full methodology · Data: CAMS via Open-Meteo (CC BY 4.0); city list: GeoNames (CC BY 4.0).

  • Good 0–50
  • Moderate 51–100
  • Unhealthy for sensitive groups 101–150
  • Unhealthy 151–200
  • Very unhealthy 201–300
  • Hazardous 301–500

Is it safe to exercise outside in Kaduna today?
For most people, yes; people with asthma, heart or lung disease, older adults and children should take it easier. The EPA’s statement for “Unhealthy for sensitive groups”: Members of sensitive groups may experience health effects. The general public is less likely to be affected.

How does Kaduna compare with other cities?
Right now it is the 152nd most polluted of 849 cities we track worldwide, and 3rd of 22 in Nigeria, all on the same US EPA scale.

Why does another app show a different AQI for Kaduna?
Apps differ in source (government stations, low-cost sensors or a model like this one), in scale (US EPA, European, or a national index) and in averaging (hourly or NowCast, 8-hour, 24-hour). This page uses the US EPA AQI with EPA’s NowCast for particles, computed from the CAMS forecast for the city’s location.
