Worst air pollution New Edinburgh - Ottawa, today and tomorrow

On 24 August 2026, overall air quality in New Edinburgh is fair. AQI is the main air quality indicator at 28.5/100. Pollution peaks around 12:00 PM (O3: 28.5/100).

On 25 August 2026, air quality conditions in New Edinburgh will be similar to today, with AQI forecast at fair at 26.7/100. Pollution peaks around 8:00 AM (O3: 26.7/100).

The colder months typically bring the heaviest particulate levels of the year to this area, driven by the combination of winter heating demand and dense traffic under calm, cold conditions. As temperatures climb, ozone typically becomes the dominant summer issue in this part of the city, which forms readily from traffic emissions baking in strong sunlight, and can spike further during wildfire smoke events.

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.
