Pocatello's air quality reflects the Portneuf River valley's topographic enclosure between the Portneuf Range and the Bannock Range in southeastern Idaho, with vehicle emissions from I-15 and the surrounding FMC Corporation phosphate chemical processing generating industrial PM2.5 alongside the primary vehicle sources. Winter temperature inversions in the valley trap emissions, while summer wildfire smoke from surrounding Idaho forests is an increasingly severe seasonal concern.

Are air quality levels in Pocatello 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.
