When is air pollution at its worst in Ashland?
Ashland sees air quality change through the year, as the wet winter and spring months are generally the cleanest, with regular rain limiting particulate buildup; by contrast, August and September wildfire smoke can dominate the season, occasionally driving particulate levels sharply higher for several days. Coastal areas see relatively little of the smoke that can settle into inland valleys during fire season.
Are air quality levels in Ashland 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.
