Oshkosh's air quality benefits from Lake Winnebago's consistent lake winds and Wisconsin northerly breezes providing reliable ventilation across this Fox River valley Wisconsin city. Vehicle emissions from US-45 and the surrounding paper and aerospace manufacturing — including Oshkosh Corporation's significant operations — contribute local sources, while summer regional ozone from Great Lakes industrial sources is the primary warm-season concern and the lake's consistent winds provide effective atmospheric washing.

When is air pollution at its worst in Oshkosh?
Oshkosh experiences a distinct seasonal swing in air quality: spring and autumn tend to bring the cleanest, most stable air, 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 Oshkosh 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.
