When is air pollution at its worst in Ancaster Village?

Summer heat can worsen conditions when plant emissions combine with sunlight to form ground-level ozone, while winter inversions occasionally trap industrial pollutants close to the ground on still, cold days. Its elevated position above the valley floor often means slightly cleaner air than the industrial areas below.

Are air quality levels in Ancaster Village 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.
