On 9 August 2026, overall air quality in Knox Mountain Park is fair. AQI is the main air quality indicator at 37.3/100. Pollution peaks around 5:00 AM (O3: 37.3/100).

On 10 August 2026, air quality conditions in Knox Mountain Park will be similar to today, with AQI forecast at fair at 21.9/100. Pollution peaks around 9:00 AM (O3: 21.9/100).

Knox Mountain Park's air quality follows a seasonal rhythm tied to its hillside parkland above Okanagan Lake. The valley's winter temperature inversions can trap cool, stagnant air and smog close to the ground, while hot, dry summers bring a real risk of wildfire smoke and orchard dust. Wind moving through the valley plays a large role in whether smoke or smog lingers or clears quickly.

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.

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.
