In Shaker Square, persistent traffic congestion paired with dense urban land use keeps particulate and nitrogen dioxide levels elevated here. Tree cover around 250 meters from here softens the impact somewhat, catching particulates before they disperse further. Wind patterns on any given day can shift this picture meaningfully in either direction.

When is air pollution at its worst in Shaker Square?
Air quality often dips most sharply in winter in this urban setting, when combined heating and traffic emissions get trapped near the ground by winter's stiller air. Summer shifts the concern toward ground-level ozone across the city, which forms readily from traffic emissions baking in strong sunlight, and can spike further during wildfire smoke events.
Are air quality levels in Shaker Square 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.
