Salisbury's air quality in Maryland reflects the flat Eastern Shore coastal plain position, with vehicle emissions from US-50 and the surrounding poultry farming and food processing industry — Salisbury being the chicken capital of the Delmarva Peninsula — contributing elevated ammonia and biological particulates alongside primary vehicle sources. Chesapeake Bay maritime influence provides periodic ventilation and the flat coastal terrain allows reasonable dispersal throughout the year.

When is air pollution at its worst in Salisbury?
Salisbury sees air quality change through the year. In short, winter generally brings the cleanest air, once the summer ozone season has passed, whereas 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 Salisbury 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.
