Green Bay's Lambeau Field air quality reflects the flat Wisconsin Fox River valley position, with vehicle traffic on Lombardi Avenue and the concentrated Green Bay Packers game day event traffic generating significant periodic vehicle emission peaks during NFL season events. Lake Michigan's regional maritime influence provides background ventilation, while the flat Wisconsin terrain allows reasonable dispersal and the stadium generally maintains moderate Green Bay metropolitan readings during non-event periods throughout the year.

When is air pollution at its worst in Lambeau Field?

Like the rest of Green Bay, Lambeau Field sees air quality change through the year: between summer ozone and occasional winter inversions, spring and fall are the year's cleanest stretch, but summer heat waves are the main driver of poor air quality, as ozone builds under stagnant, humid conditions. Lake-effect winds can help clear the air on many days near the Great Lakes shoreline.

Are air quality levels in Lambeau Field 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.
