Worst air pollution Town of Greenburgh, today and tomorrow

On 9 August 2026, overall air quality in Town of Greenburgh is fair. AQI is the main air quality indicator at 35.1/100. Pollution peaks around 11:00 AM (O3: 35.1/100).

On 10 August 2026, air quality conditions in Town of Greenburgh will be similar to today, with AQI forecast at fair at 32.4/100. Pollution peaks around 12:00 PM (O3: 32.4/100).

The depths of winter usually mark the low point for local air quality, when winter inversions trap local heating smoke in place for days at a time. Warmer months bring a different problem: ground-level ozone, since summer heat and sunlight are usually enough on their own to push ozone higher here. Milder spring and fall weather, paired with more reliable wind, usually gives the clearest air of the year.

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.

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.
