Worst air pollution Rosendal, today and tomorrow

On 9 August 2026, overall air quality in Rosendal is fair. AQI is the main air quality indicator at 31.4/100. Pollution peaks around 7:00 AM (O3: 31.4/100).

On 10 August 2026, air quality conditions in Rosendal will be better than today, with AQI forecast at good at 17.2/100. Pollution peaks around 6:00 AM (O3: 17.2/100).

Rosendal residents are most likely to notice reduced air quality on the calmest, coldest days of winter, when the surrounding mountains trap still air close to the valley floor. Frequent wind and rain along this coast generally prevent emissions from building up for long. Otherwise, Rosendal maintains good air quality across most of the calendar.

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.
