Spokane's Perry Street District air quality reflects the historic South Side arts neighbourhood, with vehicle traffic on Perry Street and the surrounding mixed residential and arts character contributing local sources. The flat terrain allows reasonable dispersal, while the neighbourhood's walkable character and the arts corridor scale generally maintain moderate Spokane metropolitan readings and summer wildfire smoke remains the primary seasonal concern throughout the year.

When is air pollution at its worst in Perry Street District?
At Perry Street District, air quality tends to follow Spokane's broader seasonal rhythm — rain-heavy winters keep the air unusually clean compared to much of the country, whereas August and September wildfire smoke can dominate the season, occasionally driving particulate levels sharply higher for several days. Winter temperature inversions can briefly trap wood-smoke in low-lying valleys, but these episodes are usually short-lived.
Are air quality levels in Perry Street District 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.
