Williamsburg's Jamestown Settlement air quality reflects the flat Virginia Tidewater Coastal Plain position, with vehicle traffic on the surrounding Jamestown Road contributing modest seasonal sources. The James River's tidal estuary provides maritime ventilation, while the surrounding colonial parkland and the river's waterway create a historic landscape that generally maintains moderate to good conditions at this important Virginia heritage site throughout most of the year.

Typically, the calmest air of the year usually arrives well after the summer ozone season fades, while summer heat waves bring the highest ozone risk, compounded by pollution drifting in from the wider region. Suburban and rural areas generally see less of the persistent traffic-driven pollution that affects the urban core.
Are air quality levels in Jamestown Settlement 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.
