Local Environmental Conditions
This location in Coorow lies in a lightly developed area, where local traffic adds relatively little to air pollution. Surrounding farmland adds dust from plowing and harvesting, ammonia from fertilizer and livestock, and smoke when crop residues are burned. Open grassland and scrub can produce smoke during grass fires and some dust in dry spells. Winds here are fairly strong, averaging around 20 km/h, which helps disperse local pollution.
Air near roads is often at its worst from June to August, when nights cool to around 12°C and the air turns still. By contrast, summer sun from November to April cooks traffic fumes into ozone, especially in the warmest month, which averages 29°C. The risk of wildfire smoke peaks from September to May, when dry vegetation burns easily.

When is air pollution at its worst in Koobabbie Precinct?
Air near roads is often at its worst from June to August, when nights cool to around 12°C and the air turns still. By contrast, summer sun from November to April cooks traffic fumes into ozone, especially in the warmest month, which averages 29°C. The risk of wildfire smoke peaks from September to May, when dry vegetation burns easily.
Are air quality levels in Koobabbie Precinct 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.
Understanding the Scale
The 0–100 air quality scores represent risk levels, not direct air pollutant concentrations. Higher scores indicate higher risk.
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
