Spokane's Chief Garry Park air quality benefits from the historic East Central neighbourhood park's greenspace providing natural filtration. Vehicle traffic on the surrounding 5th Avenue corridor contributes modest local sources, while the park's woodland and the neighbourhood's residential character generally maintain moderate Spokane metropolitan readings and summer wildfire smoke from surrounding Pacific Northwest forests is the primary seasonal concern throughout the year.

When is air pollution at its worst in Chief Garry Park?

Like the rest of Spokane, Chief Garry Park sees air quality change through the year — rain-heavy winters keep the air unusually clean compared to much of the country, whereas by late summer, wildfire smoke can override the region's usual clean-air advantage for days at a time. Winter temperature inversions can briefly trap wood-smoke in low-lying valleys, but these episodes are usually short-lived.

Are air quality levels in Chief Garry Park 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.
