Cheraw's air quality is shaped largely by humid South Carolina Sandhills air; spring pine pollen is the year's most visible seasonal event. Most days bring generally favorable conditions here, with occasional exceptions tied to shifting weather patterns. Short-term spikes are still possible even during the generally cleaner stretches of the year.

When is air pollution at its worst in Cheraw?
Air quality in Cheraw shifts across the year. In short, the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended, whereas an extended run of hot, humid afternoons in summer is when ozone most often climbs into unhealthy territory. Prescribed burns are more common in the cooler months and can add brief smoke episodes.
Are air quality levels in Cheraw 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.
