In Upper Waterfall, with vehicle traffic relatively low, dust from nearby fields and occasional burning are the bigger day-to-day factors. Nearby trees help trap a portion of this particulate load before it spreads. This general baseline tends to hold across nearby areas with similar traffic and land use. Actual air quality on a given day still depends heavily on local wind and weather conditions.

When is air pollution at its worst in Upper Waterfall?
Winter tends to bring the year's worst particulate spikes here, as cold, still air holds wood smoke and heating emissions close to the ground through winter. The warmer months shift the main air quality risk here toward bushfire smoke and ozone, since summer heat and dry vegetation nearby are usually enough on their own to raise bushfire risk.
Are air quality levels in Upper Waterfall 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.
