Being part of Mid Ulster, Cookstown sees an air quality profile that's largely down to traffic and general town-centre activity. The prevailing Atlantic airflow tend to disperse pollutants reasonably well, keeping readings close to typical UK small-town levels. The nearby A1 corridor contributes steady vehicle emissions that affect roadside readings.

When is air pollution at its worst in Cookstown?
If you're tracking air quality in Cookstown, expect it to move around quite a bit through the year. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter. Winter mornings can be the trickiest, with cold, still conditions trapping A1 traffic fumes and smoke from home fires close to the ground. The shoulder seasons generally bring the mildest readings of the year.
Are air quality levels in Cookstown 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.
