When is air pollution at its worst in Melville?
In Melville, air quality changes through the year largely because of its rail-yard heritage amid the eastern prairie. Cold winter days can trap local heating emissions close to the ground, while summer heat, farm dust and occasional wildfire smoke can push pollution higher than usual. Open prairie winds usually clear the air within a day or two of any buildup.
Are air quality levels in Melville 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.
