When is air pollution at its worst in Browne's Addition?
Browne's Addition follows Spokane's typical seasonal air quality pattern. In short, winter and spring bring the cleanest air, as frequent rain and consistent onshore wind clear pollution quickly, whereas by late summer, wildfire smoke can override the region's usual clean-air advantage for days at a time. Prevailing onshore winds usually keep pollution moving rather than letting it settle.
Are air quality levels in Browne's Addition 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.
