Local Environmental Conditions
Around this part of Merredin, dense development means road traffic is the main local source of nitrogen dioxide and fine particles. Pockets of trees and green space help filter a small share of the particles from traffic. Winds here are fairly strong, averaging around 20 km/h, which helps disperse local pollution. Air arriving from elsewhere in the region adds to what is produced locally.
Warm, sunny weather from November to March, around 27°C at its peak, raises afternoon ozone levels. From June to August, cooler nights and lighter winds, with temperatures around 10°C, let traffic pollution linger near busy roads. With little rain from November to April, dust from dry fields and open ground becomes more common. Wildfire smoke is most likely from October to May, sometimes turning the sky hazy for days.

When is air pollution at its worst in Merredin Military Museum?
Warm, sunny weather from November to March, around 27°C at its peak, raises afternoon ozone levels. From June to August, cooler nights and lighter winds, with temperatures around 10°C, let traffic pollution linger near busy roads. With little rain from November to April, dust from dry fields and open ground becomes more common. Wildfire smoke is most likely from October to May, sometimes turning the sky hazy for days.
Are air quality levels in Merredin Military Museum 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. |
