When is air pollution at its worst in Staines-upon-Thames?
Seasons make a real difference to air quality in Staines-upon-Thames, more than most people realise. Summer brings a different issue — stronger sunlight can push up ozone levels on hot, sunny days, even though traffic pollution itself often disperses more easily. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the A14 closer to ground level.
Are air quality levels in Staines-upon-Thames 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.
