Worst air pollution Desborough, today and tomorrow

On 20 September 2026, overall air quality in Desborough is fair. AQI is the main air quality indicator at 21.7/100. Pollution peaks around 9:00 AM (PM2.5: 21.7/100).

On 21 September 2026, air quality conditions in Desborough will be similar to today, with AQI forecast at fair at 34.3/100. Pollution peaks around 10:00 PM (NO2: 34.3/100).

Desborough's air quality follows a familiar seasonal pattern most UK towns share. In summer, ozone can build up on sunny afternoons, though windier, warmer weather usually helps clear traffic-related pollution faster than in winter. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the A470 closer to ground level. Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes.

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.

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.
