Frequently Asked Questions
Is air quality bad in Country Club Historic District right now?
On 20 September 2026, overall air quality in Country Club Historic District is fair. AQI is the main air quality indicator at 38.5/100. Pollution peaks around 9:00 AM (PM2.5: 38.5/100).

When is air pollution at its worst in Country Club Historic District?
October through December tends to be calm here, with wind speeds averaging around 14 km/h and temperatures near 5°C -- conditions cool and still enough for particulate matter and smoke to settle near the ground instead of dispersing. From June to August, temperatures average around 21°C, warm enough for strong sun and heat to drive ground-level ozone formation.
Are air quality levels in Country Club Historic District 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.
