In Cromer, with less congestion here, dust from surrounding fields and occasional burning plays a bigger role than traffic. This is partly offset by nearby tree cover, which filters out some particulate matter naturally. Short-term spikes can occur with unusual weather or nearby construction and traffic events. Broader regional monitoring generally reflects this same baseline, with small local variation.

When is air pollution at its worst in Cromer?
Winter tends to bring the year's worst particulate spikes here, driven by the combination of home heating and calm winter air that resists mixing. Once summer sets in, bushfire smoke haze becomes the bigger local concern on affected days, as warm, dry conditions drive both ozone formation and periodic bushfire smoke from the surrounding region.
Are air quality levels in Cromer 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.
