Local Environmental Conditions
This site in Sydney is largely built up, so vehicle exhaust and urban activity dominate the local air pollution sources. Parks and street trees provide a modest buffer against traffic pollution. Pollution carried in from the wider region can also raise levels at times. Exhaust from nearby roads is usually highest close to busy streets and junctions.
Cooler, still evenings from June to August, averaging about 14°C, tend to hold exhaust close to busy streets. Hot afternoons from December to March, averaging 23°C in the warmest month, are when ozone is most likely to build up. Breezy weather in July, with winds near 15 km/h, tends to sweep pollution away.

Hot afternoons from December to March, averaging 23°C in the warmest month, are when ozone is most likely to build up. Breezy weather in July, with winds near 15 km/h, tends to sweep pollution away.
Are air quality levels in Hyde Park Barracks 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. |
