Worst air pollution Village of Montebello, today and tomorrow

On 9 August 2026, overall air quality in Village of Montebello is fair. AQI is the main air quality indicator at 35.1/100. Pollution peaks around 11:00 AM (O3: 35.1/100).

On 10 August 2026, air quality conditions in Village of Montebello will be similar to today, with AQI forecast at fair at 32.4/100. Pollution peaks around 12:00 PM (O3: 32.4/100).

The depths of winter usually mark the low point for local air quality, when home heating emissions build up under temperature inversions common on calm winter days. As temperatures rise, ozone typically becomes the dominant summer issue around here, since intense sun and heat fuel ozone formation, sometimes compounded by regional wildfire smoke.

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.
