US EPA AQI16:00 UTC+3, 3 Nov Main pollutant: PM2.5

Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.

This page uses EPA’s NowCast, which follows the last few hours, as the US government’s AirNow does. On a 24-hour average of particles, as many apps show, it is 69.

Over the next 24 hours the model expects the AQI to range from 52 around 13:00 to 86 around 18:00 (3 Nov).

312th most polluted of 849 cities worldwide right now, 5th of 25 in Russia.

What to do today

Based on the US EPA’s health statement: “Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.” General guidance, not medical advice.

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 Rostov-on-Don’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 Rostov-on-Don right now?
80 on the US EPA scale (Moderate) at 16:00 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 Rostov-on-Don today?
For most people, yes. The EPA’s statement for “Moderate”: Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution. General guidance, not medical advice.

Will the air in Rostov-on-Don get better or worse tomorrow?
Over the next 24 hours the model expects the AQI to range from 52 around 13:00 to 86 around 18:00 (3 Nov). Forecasts beyond a day are less certain.

How does Rostov-on-Don compare with other cities?
Right now it is the 312th most polluted of 849 cities we track worldwide, and 5th of 25 in Russia, all on the same US EPA scale.

Why does another app show a different AQI for Rostov-on-Don?
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.
