Quilicura's air quality reflects the Santiago metropolitan area's northwestern industrial and residential corridor at 490 metres in the Central Valley, with vehicle traffic on surrounding roads and the manufacturing, logistics, and dense urban character contributing local sources under the Santiago basin's persistent temperature inversions. The enclosed Central Valley's near-complete topographic trapping compounds emissions extensively, while Quilicura shares the broader Santiago metropolitan air quality challenges throughout most of the year.

Will air quality be worse tomorrow in Quilicura?
On 17 July 2026, air quality conditions in Quilicura will be similar to today, with AQI forecast at good at 16.7/100. Pollution peaks around 11:00 PM (O3: 16.7/100).
When is air pollution at its worst in Quilicura?
The biggest local contributors to pollution in Quilicura are vehicle traffic and manufacturing activity, particularly once the surrounding valley traps air close to the ground. Topographic enclosure in the valley lets pollution accumulate rather than clear out. Dust carried on these winds adds substantially to particulate levels.
Are air quality levels in Quilicura 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.
