When is air pollution at its worst in Maidenhead?
If you're tracking air quality in Maidenhead, expect it to move around quite a bit through the year. Through the colder months, readings near the M8 often rise, since chimney smoke and stagnant air stop pollutants clearing away. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.
Are air quality levels in Maidenhead 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.
