Worst air pollution Nenagh, today and tomorrow

On 9 August 2026, overall air quality in Nenagh is fair. O3 is the main pollutant at 38.7/100. Pollution peaks around 6:00 AM (NO2: 43.9/100).

On 10 August 2026, air quality conditions in Nenagh will be similar to today, with AQI forecast at fair at 24.5/100. Pollution peaks around 5:00 PM (O3: 24.5/100).

Nenagh sees clear seasonal swings in air quality, driven in part by its position near the shores of Lough Derg in Tipperary. 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.

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.

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.
