When is air pollution at its worst in The Greenbrier – Old White Course?
Like the rest of Charleston, The Greenbrier – Old White Course sees air quality change through the year, as once summer humidity fades, winter typically offers the most consistently clean air; by contrast, hot, humid summer days bring the highest ozone risk, amplified by natural emissions from the dense surrounding forests. Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.
Are air quality levels in The Greenbrier – Old White Course 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.
