In Coleraine, light traffic and open farmland nearby mean seasonal dust and burning outweigh congestion as a pollution source here. Tree cover nearby helps soften the local particulate load to a degree. Conditions on any given day depend heavily on wind speed and direction locally. Nearby areas with a similar setup tend to show a comparable air quality baseline.

When is air pollution at its worst in Coleraine?
Winter months routinely bring the sharpest rise in particulate matter to this area, when home heating emissions build up under temperature inversions common on calm winter days. Warmer months bring a different problem: smoke haze from nearby bushfires, since bushfire smoke haze on affected days can outweigh the ozone increase heat alone would produce.
Are air quality levels in Coleraine 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.
