Worst air pollution Old dam wall - Metz, today and tomorrow

On 17 September 2026, overall air quality in Old dam wall is fair. AQI is the main air quality indicator at 21.3/100. Pollution peaks around 5:00 PM (O3: 21.3/100).

On 18 September 2026, air quality conditions in Old dam wall will be similar to today, with AQI forecast at fair at 31.4/100. Pollution peaks around 4:00 PM (O3: 31.4/100).

The colder months typically bring the heaviest particulate levels of the year, when home heating emissions build up under temperature inversions common on calm winter days. Summer shifts the concern toward bushfire smoke here too, since bushfire smoke haze on affected days can outweigh the ozone increase heat alone would produce. Spring and autumn tend to offer a breather, with steadier winds helping keep pollutant levels down.

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.
