Olathe's air quality benefits from the flat Kansas prairie providing excellent natural wind dispersal, with prevailing southwesterly Great Plains winds generally keeping readings at moderate levels in this affluent Kansas City southwestern suburb. Vehicle emissions from I-35 and K-7 are the primary local sources, while the Kansas City metropolitan area's regional ozone from vehicle and agricultural sources is the primary warm-season concern across this rapidly growing Johnson County suburban corridor that consistently records among Kansas's better municipal air quality readings.

Are air quality levels in Olathe 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.
