When is air pollution at its worst in Ely?

You can roughly predict Ely's air quality just by knowing the time of year. The coldest months usually bring the worst readings, as heating and temperature inversions keep A34 emissions from dispersing normally. In summer, ozone can build up on sunny afternoons, though windier, warmer weather usually helps clear traffic-related pollution faster than in winter. The shoulder seasons generally bring the mildest readings of the year.

Are air quality levels in Ely 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.
