In Rosendahl, air quality is shaped by the flat Westphalian plain, with vehicle traffic along the regional road network and nearby farming and food-processing activity as the main local sources. Open farmland surroundings generally allow pollutants to disperse readily, while the broader Rhine-Ruhr industrial background and Atlantic westerlies from the North Sea shape regional conditions throughout the year.

Is air quality bad in Rosendahl right now?
On 23 August 2026, overall air quality in Rosendahl is fair. AQI is the main air quality indicator at 24.2/100. Pollution peaks around 4:00 PM (O3: 24.2/100).

When is air pollution at its worst in Rosendahl?
Rosendahl residents notice reduced air quality mainly when hornbeam, beech, and oak pollen peaks, or on windless summer days when pollutants accumulate nearby; vehicle traffic on the surrounding road network is a modest local source. Ragweed levels remain generally low here, typical of central and western Germany. The clearest air tends to arrive after rain or on breezy afternoons.
Are air quality levels in Rosendahl 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.
