Campbell grew up around the Mahoning River steel mills, and while that heavy industry is long gone, the valley's terrain still shapes how local emissions settle. Tree cover around Mill Creek Park and along the Mahoning River helps trap a share of local particulates before they spread further. Short-term spikes can still occur during unusual weather or nearby construction.

When is air pollution at its worst in Campbell?
The coldest months tend to bring Campbell's worst particulate levels, as heating demand and traffic settle in under stagnant winter air. Warmer months bring a different challenge: ozone, formed when strong sun and heat interact with local emissions. Calm winter days in the Mahoning River valley can still concentrate traffic and heating emissions near the ground.
Are air quality levels in Campbell 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.
