Raleigh's Moore Square air quality reflects the historic downtown Raleigh park and entertainment district, with vehicle traffic on the surrounding Blount Street and Martin Street corridors contributing local sources. The Moore Square park's 2-acre greenspace provides modest local buffering, while the flat terrain allows reasonable dispersal and the district generally maintains moderate Raleigh downtown metropolitan readings throughout most of the year.

When is air pollution at its worst in Moore Square?
At Moore Square, air quality tends to follow Raleigh's broader seasonal rhythm, as the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended; by contrast, summer heat, humidity, and emissions from surrounding forests combine to drive ozone levels up. Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.
Are air quality levels in Moore Square 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.
