When is air pollution at its worst in Annapolis?
Like most US cities, Annapolis sees air quality shift from season to season, as once summer ozone season ends, winter typically offers the cleanest air; by contrast, summer heat waves bring the highest ozone risk, compounded by pollution drifting in from the wider region. Dense urban traffic corridors add a persistent background level of pollution that varies less by season than ozone does.
Are air quality levels in Annapolis 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.
