When is air pollution at its worst in Todmorden?
Spring and autumn are typically the easiest months, air-quality-wise, for most residents. Todmorden's air quality follows a familiar seasonal pattern most UK towns share. The coldest months usually bring the worst readings, as heating and temperature inversions keep M40 emissions from dispersing normally. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days.
Are air quality levels in Todmorden 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.
