In Ohio City, busy roads and concentrated city activity are the biggest single source of particulate matter in this area. Trees and green space some 100-200m from here provide a partial buffer, catching particulate matter before it spreads further. Short-term spikes can occur with unusual weather or nearby construction and traffic events.

When is air pollution at its worst in Ohio City?

Air quality often dips most sharply in winter in this urban setting, as urban heating and steady traffic emissions concentrate under inversions typical of calm winter days. As the weather warms, ozone typically overtakes particulate matter as the top concern here, as intense summer sunlight bakes traffic emissions into ground-level ozone across the urban core.

Are air quality levels in Ohio City 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.
