Bellevue's air quality in Nebraska reflects the flat Missouri River valley position adjacent to Offutt Air Force Base, with vehicle emissions from US-75 and the surrounding military and suburban character contributing local sources. The flat Great Plains terrain provides good wind dispersal, while SAC-Offutt's military aviation operations contribute localised aviation NOₓ and the broader Omaha metropolitan regional ozone from vehicle and agricultural sources is the primary warm-season concern throughout the year.

Frequently Asked Questions
Is air quality bad in Bellevue right now?
On 9 August 2026, overall air quality in Bellevue is fair. AQI is the main air quality indicator at 35.1/100. Pollution peaks around 10:00 AM (O3: 35.1/100).
Will air quality be worse tomorrow in Bellevue?
On 10 August 2026, air quality conditions in Bellevue will be similar to today, with AQI forecast at fair at 32.4/100. Pollution peaks around 11:00 AM (O3: 32.4/100).
When is air pollution at its worst in Bellevue?
Seasonal changes shape air quality across Bellevue. In short, the cleanest conditions usually come in winter, once the growing season dust and pollen have passed, whereas spring planting and autumn harvest can push particulate levels up with dust and agricultural burning. Wide-open terrain generally helps disperse pollution quickly once the wind picks up.
Are air quality levels in Bellevue 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.
