In Yorktown, lighter traffic and surrounding agricultural land make wind-blown dust and seasonal field activity bigger factors than congestion. Green space nearby provides modest natural relief, filtering a portion of this particulate load. Conditions on any given day depend heavily on wind speed and direction locally. Nearby areas with a similar setup tend to show a comparable air quality baseline.

When is air pollution at its worst in Yorktown?
From November to January, average wind speeds run around 15 km/h with temperatures near 15°C, calm and cool enough to let particulate matter and smoke build up near the ground rather than disperse. From July to September, temperatures average around 30°C, warm enough for strong sun and heat to drive ground-level ozone formation.
Are air quality levels in Yorktown 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.
