Worst air pollution Lier, today and tomorrow

On 9 August 2026, overall air quality in Lier is fair. NO2 is the main pollutant at 27.1/100. Pollution peaks around 4:00 PM (O3: 59.7/100).

On 10 August 2026, air quality conditions in Lier will be similar to today, with AQI forecast at fair at 25.5/100. Pollution peaks around 1:00 PM (O3: 25.5/100).

Residents in Lier are most likely to notice reduced air quality when oak and linden pollen peaks, or during spells of vehicle traffic and Antwerp commuter routes; conditions generally improve once the season shifts and stronger winds or rainfall return to clear the Antwerpen air. Outside these periods, most days bring reasonably steady, breathable conditions across the town.

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.
