When is air pollution at its worst in Dunstable?
You can roughly predict Dunstable's air quality just by knowing the time of year. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the A47 closer to ground level. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.
Are air quality levels in Dunstable 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.
