Bonnyrigg sits within Midlothian, and its air quality profile is driven mainly by road traffic and the density of the centre. Cooler northerly winds usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns. Rush-hour queues near the A96 are usually when readings climb the most.

When is air pollution at its worst in Bonnyrigg?

Air quality in Bonnyrigg isn't the same all year round — it really shifts with the seasons. The coldest months usually bring the worst readings, as heating and temperature inversions keep A96 emissions from dispersing normally. Summer's more of a mixed bag: ozone can spike in strong sun, but overall dispersion tends to be better than the depths of winter. Spring and autumn tend to be the calmer, more moderate stretches by comparison.

Are air quality levels in Bonnyrigg 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.
