Commuter traffic feeding onto the A1 adds a further, consistent contribution to local readings. Being part of Belfast, Botanic Gardens sees an air quality profile that's largely down to traffic and general town-centre activity. Easterly winds do most of the work keeping things in check, more so than any local policy or infrastructure change.

Frequently Asked Questions
Is air quality bad in Botanic Gardens right now?
On 9 August 2026, overall air quality in Botanic Gardens is fair. AQI is the main air quality indicator at 25.6/100. Pollution peaks around 1:00 PM (O3: 25.6/100).

When is air pollution at its worst in Botanic Gardens?
The shoulder seasons generally bring the mildest readings of the year. You can roughly predict Botanic Gardens's air quality just by knowing the time of year. In deep winter, a lack of wind lets A1 traffic fumes and woodsmoke settle instead of blowing through. 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.
Are air quality levels in Botanic Gardens 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.
