When is air pollution at its worst in Havant?
In Havant, pollution levels don't stay flat — winter and summer look pretty different. Winter mornings can be the trickiest, with cold, still conditions trapping A40 traffic fumes and smoke from home fires close to the ground. 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 Havant 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.
