Quillota's air quality reflects the Chilean Valparaíso Region's Aconcagua River valley position at 127 metres, with vehicle traffic on surrounding roads and the table grape, fruit, and agricultural corridor contributing local sources. The coastal Cordillera partially blocks Pacific maritime ventilation, while the valley's topographic enclosure creates concentration under winter inversions and Quillota generally maintains moderate Chilean Valparaíso metropolitan agricultural valley readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Quillota right now?
On 9 August 2026, overall air quality in Quillota is good. AQI is the main air quality indicator at 18.2/100. Pollution peaks around 10:00 PM (O3: 18.2/100).
Will air quality be worse tomorrow in Quillota?

When is air pollution at its worst in Quillota?
Pollution in Quillota typically rises when traffic on the surrounding roads and agricultural activity combine, especially once temperature inversions set in over the valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Quillota based on measurements or forecasts?
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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
