When is air pollution at its worst in Truro?
Spring and autumn tend to be the calmer, more moderate stretches by comparison. There's a clear yearly cycle to air quality in Truro if you look closely. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the M6 closer to ground level. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter.
Are air quality levels in Truro 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.
