In Yarrowyck, traffic stays fairly light here, leaving wind-blown dust from nearby fields as a bigger factor than vehicle emissions. Tree cover is limited nearby, restricting any natural filtering effect on local particulates. Local monitoring for the wider area tends to track closely with this general pattern. Conditions on any given day depend heavily on wind speed and direction locally.

When is air pollution at its worst in Yarrowyck?
Particulate levels here tend to peak during the coldest months of the year, when winter inversions trap local heating smoke in place for days at a time. As the weather warms and fire risk rises, smoke haze tends to overtake other concerns in this area, as warm, dry conditions drive both ozone formation and periodic bushfire smoke from the surrounding region.
Are air quality levels in Yarrowyck 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.
