When is air pollution at its worst in Basingstoke?
You can roughly predict Basingstoke's air quality just by knowing the time of year. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. The coldest months usually bring the worst readings, as heating and temperature inversions keep M74 emissions from dispersing normally. Most of spring and autumn stays fairly steady, right in the middle of those two extremes.
Are air quality levels in Basingstoke 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.
