On 9 August 2026, overall air quality in Village of Old Westbury is fair. AQI is the main air quality indicator at 38.1/100. Pollution peaks around 11:00 AM (O3: 38.1/100).

On 10 August 2026, air quality conditions in Village of Old Westbury will be similar to today, with AQI forecast at fair at 36.1/100. Pollution peaks around 11:00 AM (O3: 36.1/100).

Cold-season conditions typically drive the sharpest particulate increases around here, when home heating emissions build up under temperature inversions common on calm winter days. By summer, ozone becomes the more pressing issue in this area, as hot, sunny days accelerate local ozone formation, occasionally compounded by drifting smoke. Spring and fall typically bring a welcome improvement, as milder temperatures and better wind flow clear the air.

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.
