In Ryckmans Corners, heavy vehicle traffic and general city activity keep background particulate matter and nitrogen dioxide levels elevated. Nearby trees help trap a portion of this particulate load before it spreads. This general baseline tends to hold across nearby areas with similar traffic and land use. Actual air quality on a given day still depends heavily on local wind and weather conditions.

When is air pollution at its worst in Ryckmans Corners?

The colder months typically bring the heaviest particulate levels of the year to this area, when winter inversions hold traffic and heating emissions in place over the city for days at a time. By summer, ozone becomes the more pressing urban issue, since hot, sunny days accelerate the chemical reactions that turn traffic emissions into ozone.

Are air quality levels in Ryckmans Corners 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.
