When is air pollution at its worst in Blackburn?
Blackburn's air quality follows a familiar seasonal pattern most UK towns share. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. Through the colder months, readings near the M11 often rise, since chimney smoke and stagnant air stop pollutants clearing away. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.
Are air quality levels in Blackburn 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.
