In Riesa, air quality is shaped by the Elbe valley and Erzgebirge foothills, with vehicle traffic along the regional road network and surrounding manufacturing and farming activity as the main local sources. The river valley setting can concentrate pollutants under calm conditions, while the broader Saxon industrial background and regional airflow shape conditions throughout the year.

Frequently Asked Questions

Is air quality bad in Riesa right now?

On 21 July 2026, overall air quality in Riesa is fair. AQI is the main air quality indicator at 26.6/100. Pollution peaks around 6:00 PM (O3: 26.6/100).

When is air pollution at its worst in Riesa?

You're most likely to notice worse air in Riesa when birch, ash, and linden pollen peaks, or on still, humid days when emissions linger locally; everyday local traffic contributes a modest, fairly steady source. Ragweed levels rise modestly here from mid-August under the region's continental climate. Early mornings after overnight rain usually offer the freshest air.

Are air quality levels in Riesa 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.
