When is air pollution at its worst in Trim?
Conditions in Trim shift with the calendar, largely because of its riverside setting beneath Trim Castle on the River Boyne. Winter's calmest, coldest nights bring the year's main dip in air quality from solid-fuel heating smoke, while frequent rain and wind keep the rest of the year clean. A change in the weather, which happens often in Ireland, usually clears any smoke within a day or two.
Are air quality levels in Trim 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.
