When is air pollution at its worst in Watrous?
In Watrous, air quality changes through the year largely because of the mineral-rich waters of nearby Manitou Lake. Air quality is typically excellent for much of the year, though summer weekends bring a rise in vehicle traffic from visitors, and occasional wildfire smoke can drift in during hot, dry stretches. Weekday air quality is often noticeably better than on busy summer weekends when visitor numbers peak.
Are air quality levels in Watrous 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.
