The air quality picture in RHS Wisley Gardens reflects a typical London, City of town, with traffic emissions and local commercial activity as key contributors. The M1 generates consistent traffic-related NO₂ and PM2.5, particularly during peak commuting hours. Inland breezes from the surrounding countryside generally provide reasonable ventilation, keeping levels close to typical UK urban averages for a town this size.

When is air pollution at its worst in RHS Wisley Gardens?
The shoulder seasons generally bring the mildest readings of the year. Here's the thing about RHS Wisley Gardens: air quality has a clear seasonal rhythm. Winter mornings can be the trickiest, with cold, still conditions trapping M1 traffic fumes and smoke from home fires close to the ground. Summer brings a different issue — stronger sunlight can push up ozone levels on hot, sunny days, even though traffic pollution itself often disperses more easily.
Are air quality levels in RHS Wisley Gardens 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.
