In College Park, Washington DC beltway corridor emissions is the main influence on air quality, and proximity to the capital region means summer ozone is the main seasonal concern. Day-to-day conditions in College Park can still vary with local weather, wind direction, and time of year. Local topography and prevailing winds both play a role in how quickly conditions change.

When is air pollution at its worst in College Park?
Like most US cities, College Park sees air quality shift from season to season. In short, winter generally brings the cleanest air, once the summer ozone season has passed, whereas 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 College Park 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.
