Modelled concentrations at the city’s location (CAMS). The sub-index uses the same averaging as the headline, so the highest one is the AQI.

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 Moscow’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

Questions

What is the AQI in Moscow right now?
168 on the US EPA scale (Unhealthy) at 15:00 UTC+3, 3 Nov. PM2.5 is the pollutant with the highest sub-index. This is a modelled estimate from the Copernicus Atmosphere Monitoring Service (CAMS), not a reading from a monitoring station.

Is it safe to exercise outside in Moscow today?
Consider shortening outdoor exercise; sensitive groups should move it indoors. The EPA’s statement for “Unhealthy”: Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects. General guidance, not medical advice.

Will the air in Moscow get better or worse tomorrow?
Over the next 24 hours the model expects the AQI to range from 66 around 05:00 to 164 around 16:00 (3 Nov). Forecasts beyond a day are less certain.

How does Moscow compare with other cities?
Right now it is the 42nd most polluted of 849 cities we track worldwide, and 1st of 25 in Russia, all on the same US EPA scale.

Why does another app show a different AQI for Moscow?
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.
