Chesapeake's air quality benefits from its Chesapeake Bay and Elizabeth River estuary position in the Virginia Beach-Norfolk metropolitan area, with consistent Atlantic and bay breezes providing reliable maritime ventilation. Vehicle emissions from I-64 and the Chesapeake Expressway and the Naval Station Norfolk military vehicle activity are the primary local sources, while the bay's geography generally provides good ventilation and keeps Chesapeake's readings moderate for a major southeastern US metropolitan area.

When is air pollution at its worst in Chesapeake?
Like most US cities, Chesapeake sees air quality shift from season to season: once summer ozone season ends, winter typically offers the cleanest air, but the hottest, most humid summer weeks bring the year's highest ozone readings. Suburban and rural areas generally see less of the persistent traffic-driven pollution that affects the urban core.
Are air quality levels in Chesapeake 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.
