Clay's air quality in New York reflects the flat Onondaga County terrain north of Syracuse, with vehicle emissions from I-481 and the surrounding suburban residential character of this major Syracuse northern suburb contributing local sources. Lake Ontario's northern influence provides some regional lake ventilation, while summer regional ozone from Great Lakes industrial sources is the primary warm-season concern and lake-effect weather patterns provide effective atmospheric washing throughout the year.

When is air pollution at its worst in Clay, New York?
Air quality in Clay shifts across the year — frequent frontal systems in spring and fall usually keep the air cleanest then, whereas the combination of local heat and imported regional haze peaks during summer. Winter cold fronts tend to clear the air quickly, so extended pollution episodes are relatively uncommon.
Are air quality levels in Clay, New York 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.
