When is air pollution at its worst in Halesworth?
Seasons make a real difference to air quality in Halesworth, more than most people realise. Through the colder months, readings near the M4 often rise, since chimney smoke and stagnant air stop pollutants clearing away. In summer, ozone can build up on sunny afternoons, though windier, warmer weather usually helps clear traffic-related pollution faster than in winter. The shoulder seasons generally bring the mildest readings of the year.
Are air quality levels in Halesworth 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.
