When is air pollution at its worst in Riverside Avenue?
This neighborhood in Spokane sees air quality shift through the year — rain-heavy winters keep the air unusually clean compared to much of the country, whereas the driest weeks of late summer bring the greatest risk of smoke drifting in from regional wildfires. Prevailing onshore winds usually keep pollution moving rather than letting it settle.
Are air quality levels in Riverside Avenue 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.
