Worst air pollution Odivelas, today and tomorrow

On 21 July 2026, overall air quality in Odivelas is fair. AQI is the main air quality indicator at 40.0/100. Pollution peaks around 3:00 PM (O3: 40.0/100).

On 22 July 2026, air quality conditions in Odivelas will be similar to today, with AQI forecast at fair at 33.7/100. Pollution peaks around 5:00 PM (O3: 33.7/100).

Residents in Odivelas are most likely to spot reduced air quality when pine and eucalyptus pollen peaks, or due to vehicle traffic on the IC22 CRIL and the A8 motorways and the dense suburban residential character; a change of season or a spell of wind usually clears things up again.

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.
