In Roanoke-Randolph Street Historic District, lighter traffic and surrounding agricultural land make wind-blown dust and seasonal field activity bigger factors than congestion. This is partly offset by tree cover about 178 meters away, which filters out some particulate matter naturally. Day-to-day readings still shift with wind direction, traffic volume, and weather conditions.

When is air pollution at its worst in Roanoke-Randolph Street Historic District?
Cold-season conditions typically drive the sharpest particulate increases around here, as rural heating sources add up under inversions that keep smoke from dispersing. By summer, ozone becomes the more pressing issue in this area, as heat and sunlight drive photochemical smog, occasionally worsened by drifting wildfire smoke. Spring and fall typically bring a welcome improvement, as milder temperatures and better wind flow clear the air.
Are air quality levels in Roanoke-Randolph Street 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.
