Bacchus Marsh, set in a valley near the Werribee River between Melbourne and the Great Dividing Range, has orchards and market gardens as a defining feature of its rural landscape, contributing modest seasonal dust. The valley setting can trap cool air and wood heater smoke on still winter nights. Its proximity to Melbourne brings increasing traffic and construction activity as the town grows, adding to background pollution levels. Dry summer conditions carry a bushfire smoke risk from surrounding forested hills. Overall, air quality remains generally good, typical of peri-urban Victorian towns.

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.
