Palatine's air quality reflects the flat Illinois prairie northwest of Chicago adjacent to O'Hare Airport's northern approach, with vehicle emissions from I-90 and the surrounding suburban residential and commercial corridor contributing local sources. The broader Chicago metropolitan regional ozone from prevailing southwesterly winds and the O'Hare Airport's flight corridor make Palatine one of the Chicago area's more aviation-influenced northwestern suburban communities throughout the year.

In short, the cleanest stretches usually come in spring and fall, between the summer ozone season and the calmer winter pollution episodes, whereas 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 Palatine 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.
