Modbury sits in Adelaide's north-eastern suburbs, a flatter, more inland setting than the adjacent hills-fringe areas, where traffic around its major shopping centre, Tea Tree Plaza, is the dominant local air quality factor. Sea-breeze ventilation from Gulf St Vincent reaches the area, though less directly than coastal suburbs. Bushfire smoke is a periodic summer risk from the nearby Adelaide Hills. There is no industry present. Overall, background air quality here is generally good but more traffic-influenced than the elevated hills suburbs nearby.

When is air pollution at its worst in Modbury?

Modbury's air quality generally follows Adelaide's seasonal pattern, with summer bushfire smoke, December to March, from the surrounding hills the main factor to expect during hot, windless conditions. The rest of the year typically sees clear, breeze-flushed air across this north-eastern suburb.

Are air quality levels in Modbury 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.
