Achern sits within the Black Forest foothills and upper Rhine valley, where local traffic and nearby regional through-roads and nearby tourism and small-scale manufacturing contribute the main local air quality sources. Lake and forest proximity generally support reasonable dispersal, while regional airflow off the Black Forest keeps background pollution levels comparatively low throughout the year.

Frequently Asked Questions

Is air quality bad in Achern right now?

On 23 August 2026, overall air quality in Achern is fair. AQI is the main air quality indicator at 33.3/100. Pollution peaks around 2:00 AM (NO2: 33.3/100).

Will air quality be worse tomorrow in Achern?

On 24 August 2026, air quality conditions in Achern will be similar to today, with AQI forecast at fair at 38.1/100. Pollution peaks around 5:00 PM (O3: 38.1/100).

When is air pollution at its worst in Achern?

The most noticeable dips in Achern's air quality come when oak, spruce, and linden pollen peaks, or on windless summer days when pollutants accumulate nearby; local traffic and occasional agricultural or industrial activity add modest sources. The warmer, more continental climate here brings a modest ragweed presence from mid-August. Breezy days and periods of rain generally bring the clearest conditions.

Are air quality levels in Achern 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.
