Yonkers' air quality reflects its position as New York City's most immediate northern neighbour in Westchester County, with the Saw Mill River Parkway and the Cross County Parkway generating concentrated commuter vehicle emissions alongside the densely urban character of this Hudson River city. The Hudson River provides some ventilation from the west, while the prevailing southwesterly winds carry the entire New York metropolitan area's pollution burden northward through the Hudson valley corridor directly through Yonkers throughout the year.

When is air pollution at its worst in Yonkers?
Like most US cities, Yonkers sees air quality shift from season to season. Typically, frequent frontal systems in spring and fall usually keep the air cleanest then, while summer heat waves, often worsened by haze drifting in from other regions, bring the year's worst air. Winter cold fronts tend to clear the air quickly, so extended pollution episodes are relatively uncommon.
Are air quality levels in 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.
