Terre Haute's air quality reflects the Wabash River valley's flat terrain at the Illinois-Indiana border, with vehicle emissions from I-70 and the surrounding pharmaceutical manufacturing and energy sector — including significant coal power station legacy — contributing local sources. The flat Wabash Valley provides reasonable dispersal, while summer ozone from the Ohio Valley regional airshed and industrial background from the energy corridor are the primary air quality concerns throughout the year.

When is air pollution at its worst in Terre Haute?
Terre Haute sees air quality change through the year — spring and autumn tend to bring the cleanest, most stable air, whereas summer heat waves are the main driver of poor air quality, as ozone builds under stagnant, humid conditions. Calm, cold winter spells can occasionally allow local pollution to build up before the next weather system clears it.
Are air quality levels in Terre Haute 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.
