Spokane's East Central air quality reflects the historic residential neighbourhood, with vehicle traffic on the surrounding East Sprague Avenue corridor contributing local sources. The flat terrain allows reasonable dispersal, while the neighbourhood's residential character and the Inland Northwest background provide reasonable conditions throughout most non-wildfire periods, with summer wildfire smoke remaining the primary seasonal air quality concern throughout the year.

When is air pollution at its worst in East Central Spokane?

In short, the wet winter and spring months are generally the cleanest, with regular rain limiting particulate buildup, whereas the driest weeks of late summer bring the greatest risk of smoke drifting in from regional wildfires. Coastal areas see relatively little of the smoke that can settle into inland valleys during fire season.
Are air quality levels in East Central Spokane 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.
