Limerick's air quality is generally good by Irish standards, benefiting from Ireland's Atlantic exposure and the Shannon River estuary providing reliable ventilation across this mid-western Irish city. Vehicle traffic on the M7 and the surrounding pharmaceutical and technology manufacturing — including Analog Devices and other major operations — contribute local sources, while the Atlantic maritime climate's stormy weather provides effective natural atmospheric washing and Limerick's pharmaceutical corridor is the most distinctive industrial emission source throughout the year.

When is air pollution at its worst in Limerick?
Seasonal air quality in Limerick is closely linked to its position on the River Shannon in the country's mid-west. Damp, breezy conditions dominate most of the year, though calm, cold winter evenings occasionally let traffic fumes and coal or turf smoke linger over the city. A change in the wind, which happens often here, usually clears the air within a day.
Are air quality levels in Limerick 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
