When is air pollution at its worst in North Carolina Arboretum?
North Carolina Arboretum's air quality follows a clear seasonal pattern, as the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended; 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 North Carolina Arboretum 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.
