Being part of Bradford, Ilkley sees an air quality profile that's largely down to traffic and general town-centre activity. Emissions along the M90 represent the town's main traffic-related pollution source. Onshore breezes do most of the work keeping things in check, more so than any local policy or infrastructure change.

When is air pollution at its worst in Ilkley?

Here's the thing about Ilkley: air quality has a clear seasonal rhythm. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the M90 closer to ground level. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. Spring and autumn tend to be the calmer, more moderate stretches by comparison.

Are air quality levels in Ilkley 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.
