Baltimore's Locust Point air quality reflects the South Baltimore waterfront industrial peninsula adjacent to the Fort McHenry National Monument, with vehicle traffic on Key Highway and the surrounding mixed residential and industrial terminal operations contributing local sources. The Patapsco River and Fort McHenry Channel provide limited maritime ventilation, while the industrial port character and the CSX and Domino Sugar terminal operations maintain moderate to above-average Baltimore industrial waterfront readings throughout most of the year.

When is air pollution at its worst in Locust Point?
At Locust Point, air quality tends to follow Baltimore's broader seasonal rhythm. Typically, once summer ozone season ends, winter typically offers the cleanest air, while hot, humid summer conditions and regional haze drive ozone spikes, especially during heat waves. Dense urban traffic corridors add a persistent background level of pollution that varies less by season than ozone does.
Are air quality levels in Locust Point 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
