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 Dhaka’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 Dhaka right now?
151 on the US EPA scale (Unhealthy) at 18:00 UTC+6, 3 Nov. O₃ 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 Dhaka 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 Dhaka get better or worse tomorrow?
Over the next 24 hours the model expects the AQI to range from 100 around 12:00 to 160 around 22:00 (3 Nov). Forecasts beyond a day are less certain.

How does Dhaka compare with other cities?
Right now it is the 96th most polluted of 849 cities we track worldwide, and 3rd of 7 in Bangladesh, all on the same US EPA scale.

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