Spokane's South Hill air quality benefits from its elevated position above the Spokane River valley, with vehicle traffic on the surrounding 29th Avenue corridor contributing local sources. The elevated position provides marginally better dispersal than the valley floor during winter inversions, while the neighbourhood's residential character and the consistent Inland Northwest westerly airflows generally maintain South Hill among Spokane's more moderate residential environments throughout most of the year.

Are air quality levels in South Hill 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.
