Through the colder months, readings near the M20 often rise, since chimney smoke and stagnant air stop pollutants clearing away. Spring and autumn are typically the easiest months, air-quality-wise, for most residents.
Are air quality levels in Elephant & Castle 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.
