Menlyn lies roughly 50 km north-northeast of Johannesburg. Vehicle traffic and government, finance, and commercial operations together shape most of what happens to air quality at Menlyn, sitting as it does on the open Highveld plateau. Winter's still, cold mornings are when the two combine most noticeably, before summer's stronger winds take over and clear things out. This is roughly what you'd expect anywhere on the open plateau.

When is air pollution at its worst in Menlyn?
Ask anyone at Menlyn and they'll say winter mornings are when the air is at its worst, as government, finance, and commercial operations and local traffic emissions sit trapped under a still, cold inversion layer. Spring and summer bring the wind and rain that usually clears things up again. This is a familiar pattern across much of the Highveld.
Are air quality levels in Menlyn 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.
