In Homberg (Efze), air quality is shaped by the hilly North Hessian countryside, with traffic on the surrounding road network and surrounding agricultural and light industrial activity as the main local sources. Forested slopes give some shelter but uneven dispersal patterns, while Atlantic westerlies and the region's forested upland setting keep background levels moderate throughout the year.

Frequently Asked Questions

Is air quality bad in Homberg (Efze) right now?

On 21 July 2026, overall air quality in Homberg (Efze) is fair. AQI is the main air quality indicator at 27.0/100. Pollution peaks around 5:00 PM (O3: 27.0/100).

When is air pollution at its worst in Homberg (Efze)?

People in Homberg (Efze) tend to notice reduced air quality when ash, maple, and oak pollen peaks, or on hot, still days when local emissions build up; regional road traffic is a modest local source. This part of Germany typically experiences only light ragweed levels overall. Rain and wind both tend to clear the air fairly quickly here.

Are air quality levels in Homberg (Efze) 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.
