Khulna's air quality reflects the flat Bangladesh Rupsha River delta position at 3 metres adjacent to the Sundarbans mangrove reserve, with vehicle traffic on surrounding roads and the ship breaking, jute processing, and vehicle density corridor generating elevated PM2.5 and heavy metals. The Bay of Bengal monsoon provides wet season cleansing, while the dry season northeast monsoon concentrates industrial emissions and Khulna generally maintains moderate to elevated Bangladeshi southwestern industrial port readings throughout most of the year.

When is air pollution at its worst in Khulna?
The biggest local contributors to pollution in Khulna are traffic on the surrounding roads together with harbour and shipping traffic, particularly once windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. Rains during the wetter months typically wash pollutants out of the air.
Are air quality levels in Khulna based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
