In City of Yonkers, with lighter traffic here, particulate matter tends to come more from farmland dust and occasional burning than from vehicles. A patch of green space in the area offers some natural buffering against local particulate matter. Actual air quality on a given day still depends heavily on local wind and weather conditions.

When is air pollution at its worst in City of Yonkers?

The depths of winter usually mark the low point for local air quality, driven by the combination of home heating and calm winter air that resists mixing. Warmer months bring a different problem: ground-level ozone, which forms readily in strong sunlight and heat, and can spike further during wildfire smoke events.

Are air quality levels in City of Yonkers 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.
