In Granville Historic District, with traffic fairly sparse here, dust kicked up from nearby farmland tends to matter more than vehicle emissions. A patch of green space roughly 50m away offers some natural buffering against local particulate matter. Daily conditions can shift noticeably depending on wind, temperature, and traffic patterns.

When is air pollution at its worst in Granville Historic District?
Winter tends to bring the year's worst particulate spikes here, as cold, still air holds wood smoke and heating emissions close to the ground through winter. Summer heat pushes ozone to the forefront of local air quality concerns, since intense sun and heat fuel ozone formation, sometimes compounded by regional wildfire smoke.
Are air quality levels in Granville Historic District 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.
