Alfeld sits within the inland Lower Saxon countryside near the Harz foothills, where vehicle traffic on local and regional roads and surrounding agricultural and light manufacturing activity contribute the main local air quality sources. Gently rolling terrain generally allows moderate pollutant dispersal, while regional airflow from the west and limited heavy industry keep background pollution moderate throughout the year.

Frequently Asked Questions

Is air quality bad in Alfeld right now?

On 21 July 2026, overall air quality in Alfeld is fair. AQI is the main air quality indicator at 26.8/100. Pollution peaks around 6:00 PM (O3: 26.8/100).

When is air pollution at its worst in Alfeld?

You're most likely to notice worse air in Alfeld when birch, maple, and oak pollen peaks, or on windless summer days when pollutants accumulate nearby; everyday driving through the area contributes a modest amount. Ragweed exposure stays modest in this part of Germany through late summer. Early mornings after overnight rain usually offer the freshest air.

Are air quality levels in Alfeld 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.
