When is air pollution at its worst in Tower of London?
Tower of London doesn't have one fixed air quality level — it swings between two extremes each year. In deep winter, a lack of wind lets A34 traffic fumes and woodsmoke settle instead of blowing through. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter. Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes.
Are air quality levels in Tower of London 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.
