When is air pollution at its worst in Golf de Saint-Germain – Championship Course?
Golfers at Golf de Saint-Germain – Championship Course are most likely to notice reduced air quality when pollen from oak, plane trees, and birch peaks, or on hot, still days when local emissions build up; regional traffic contributes modest local sources, with summer ozone building on hot, still days. Greater Paris sees a mild ragweed presence build from late August, generally lighter than in the Rhône Valley further south. The extensive forests surrounding these courses generally provide good natural filtration.
Are air quality levels in Golf de Saint-Germain – Championship Course 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.
