Worst air pollution Gallarate, today and tomorrow

On 9 August 2026, overall air quality in Gallarate is fair. PM1 is the main pollutant at 26.2/100. Pollution peaks around 3:00 PM (O3: 57.4/100).

On 10 August 2026, air quality conditions in Gallarate will be similar to today, with PM1 forecast at fair at 29.5/100. Pollution peaks around 1:00 PM (O3: 58.4/100).

Gallarate residents notice reduced air quality mainly when local combined tree and grass pollen peaks, and during spells of vehicle traffic on the A8 motorway and the nearby manufacturing and Malpensa Airport's significant aviation operations; the remainder of the year typically brings clearer, more consistent conditions.

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.
