Worst air pollution Blair Atholl Golf & Equestrian Estate – Championship Course - Johannesburg, today and tomorrow

On 19 July 2026, overall air quality in Blair Atholl Golf & Equestrian Estate – Championship Course is fair. PM2.5 is the main pollutant at 36.8/100. Pollution peaks around 3:00 AM (HCHO: 47.7/100).

On 20 July 2026, air quality conditions in Blair Atholl Golf & Equestrian Estate – Championship Course will be similar to today, with O3 forecast at fair at 29.5/100. Pollution peaks around 3:00 AM (HCHO: 54.3/100).

Blair Atholl's location near Lanseria means light aircraft traffic occasionally adds to the mix, though the estate's open equestrian land and lower housing density generally keep air quality better than in denser Johannesburg suburbs. Winter mornings remain the main exception, when still air can trap dust from the surrounding grassland.

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.
