Worst air pollution Buchholz in der Nordheide, today and tomorrow

On 20 September 2026, overall air quality in Buchholz in der Nordheide is good. AQI is the main air quality indicator at 18.2/100. Pollution peaks around 11:00 PM (O3: 18.2/100).

On 21 September 2026, air quality conditions in Buchholz in der Nordheide will be similar to today, with AQI forecast at good at 18.5/100. Pollution peaks around 1:00 AM (O3: 18.5/100).

In Buchholz in der Nordheide, the days to watch are when alder, ash, and birch pollen peaks, or warm, windless days when local pollution accumulates; day-to-day road traffic here stays a fairly minor, steady source. The coastal maritime influence here keeps ragweed presence minimal, unlike in southern Germany. Rain and wind both tend to clear the air fairly quickly here.

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.
