Conway's air quality reflects the flat Arkansas River valley terrain in central Arkansas, with vehicle emissions from I-40 and the surrounding University of Central Arkansas campus and suburban growth contributing local sources. The flat Arkansas valley plain provides generally good wind dispersal, while summer ozone from regional vehicle and agricultural sources across the broader Arkansas Valley airshed is the primary warm-season concern throughout the year.

When is air pollution at its worst in Conway?
Conway sees air quality change through the year: the cleanest stretches usually come in spring and fall, between the summer ozone season and the calmer winter pollution episodes, but 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 Conway 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.
