When is air pollution at its worst in Copper Harbor?
Copper Harbor follows a fairly predictable seasonal air quality pattern, as spring and autumn tend to bring the cleanest, most stable air; by contrast, summer heat waves are the main driver of poor air quality, as ozone builds under stagnant, humid conditions. Calm, cold winter spells can occasionally allow local pollution to build up before the next weather system clears it.
Are air quality levels in Copper Harbor 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.
