Groningen's air quality is generally good by Dutch standards, benefiting from consistent North Sea westerlies providing clean Atlantic maritime ventilation across this flat northeastern Netherlands university city. Vehicle traffic on the N7 and surrounding road network are the primary local sources, while the flat Groningen polder plain allows good dispersal on most days. The Slochteren natural gas field's historic production infrastructure in the surrounding region contributes background methane, though direct PM2.5 impacts are limited.

When is air pollution at its worst in Groningen?
People visiting or living in Groningen generally notice the biggest dip in air quality through spring and into early summer, when birch, oak, and alder pollen peaks, or on windless, warm days when traffic on the N7 and industry emissions gather; coastal winds off the Wadden Sea help keep the air moving. For most of the year, air quality here tracks closely with typical conditions across the Netherlands.
Are air quality levels in Groningen 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.
