In Fort Howard, road traffic and general city density are the leading contributors to particulate matter and nitrogen dioxide here. Nearby tree cover helps filter some of this particulate load before it settles over the neighborhood. The surrounding area tends to follow a similar pattern, with only minor local variation.

When is air pollution at its worst in Fort Howard?
Winter tends to bring the year's worst particulate spikes here, as urban heating and steady traffic emissions concentrate under inversions typical of calm winter days. Summer shifts the concern toward ground-level ozone across the city, since dense traffic emissions combined with intense sun and heat fuel ozone formation across the city. Spring and fall typically bring a welcome improvement, as milder temperatures and better wind flow clear the air.
Are air quality levels in Fort Howard 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.
