Worst air pollution The A Frame - The Percy Group, today and tomorrow

Today (21 September): Air quality in The A Frame is fair. AQI, PM2.5, and PM10 are fair; NO2, O3, SO2, CO, HCHO, and PM1 are good. Pollution peaks around 12:00 PM (PM2.5: 34.3/100).
Tomorrow (22 September 2026): Air quality in The A Frame is fair. PM10 decreases to good; all other pollutants stay as today. Pollution peaks around 10:00 AM (PM2.5: 32.2/100). Airmine updates local air quality forecasts four times daily.

In The A Frame, lighter traffic and surrounding agricultural land make wind-blown dust and seasonal field activity bigger factors than congestion. With little tree cover close by, there's not much practical buffering against local particulates. The surrounding area tends to follow a similar pattern, with only minor local variation. Wind patterns on any given day can shift this picture meaningfully in either direction.

Frequently Asked Questions

Is air quality bad in The A Frame right now?

On 21 September 2026, overall air quality in The A Frame is fair. AQI is the main air quality indicator at 34.3/100. Pollution peaks around 12:00 PM (PM2.5: 34.3/100).

Will air quality be worse tomorrow in The A Frame?

On 22 September 2026, air quality conditions in The A Frame will be similar to today, with AQI forecast at fair at 32.2/100. Pollution peaks around 10:00 AM (PM2.5: 32.2/100).

When is air pollution at its worst in The A Frame?

The colder months typically bring the heaviest particulate levels of the year, when home heating emissions build up under temperature inversions common on calm winter days. Summer heat and dry conditions nearby make bushfire smoke the leading local air quality issue, since summer heat and dry vegetation nearby are usually enough on their own to raise bushfire risk.

Are air quality levels in The A Frame 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.
