When is air pollution at its worst in Roscommon?
Year-round, Roscommon's air quality is closely tied to its lake-dotted farmland setting in the midlands. 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. Away from the town centre, conditions tend to stay a little cleaner even on the stillest winter nights.
Are air quality levels in Roscommon 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.
