Spokane's West Central air quality reflects the historic residential neighbourhood, with vehicle traffic on the surrounding Northwest Boulevard corridor contributing local sources. The flat terrain allows reasonable dispersal, while the neighbourhood's residential character and the Inland Northwest westerly airflows provide background ventilation and West Central generally maintains moderate Spokane metropolitan readings throughout most of the year.

When is air pollution at its worst in West Central?
This neighborhood in Spokane sees air quality shift through the year. In short, 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 West Central 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.
