Given its location — a capitol set in a landscaped downtown square shaded by oaks — South Carolina State House shares Columbia's wider air quality pattern rather than a distinct local one. Any local variation tends to be minor compared with the seasonal swings seen across the wider city.

When is air pollution at its worst in South Carolina State House?
At South Carolina State House, air quality tends to follow Columbia's broader seasonal rhythm. Typically, mild winter weather usually brings the year's cleanest air, while 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 South Carolina State House 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.
