Local Environmental Conditions
This site in Sydney combines built-up streets with more open land, so local traffic matters, though emissions are less concentrated than in a city center. The surrounding woodland releases natural compounds that, in warm sunny weather, help form ozone. Winds are often light, which allows pollutants to linger close to where they are produced. Air arriving from elsewhere in the region adds to what is produced locally.
Cooler, still evenings from June to August, averaging about 12°C, tend to hold exhaust close to busy streets. Ozone is the main concern from November to March, when sunny days averaging 23°C turn traffic and other emissions into ozone by mid-afternoon. Short-term changes follow the weather: calm spells raise levels, while breezy or rainy days lower them.

Short-term changes follow the weather: calm spells raise levels, while breezy or rainy days lower them.
Are air quality levels in Pennant Hills Golf Club 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. |
