When is air pollution at its worst in Grimsby?
Spring and autumn tend to be the calmer, more moderate stretches by comparison. Grimsby doesn't have one fixed air quality level — it swings between two extremes each year. The coldest months usually bring the worst readings, as heating and temperature inversions keep A46 emissions from dispersing normally. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter.
Are air quality levels in Grimsby 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.
