When is air pollution at its worst in Green Lake Park?
Like the rest of Seattle, Green Lake Park sees air quality change through the year. In short, winter and spring bring the cleanest air, as frequent rain and consistent onshore wind clear pollution quickly, whereas August and September wildfire smoke can dominate the season, occasionally driving particulate levels sharply higher for several days. Prevailing onshore winds usually keep pollution moving rather than letting it settle.
Are air quality levels in Green Lake 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.
