La Granja's air quality reflects the Santiago metropolitan area's northern industrial and residential corridor at 497 metres in the Central Valley, with vehicle traffic on surrounding roads and the manufacturing, industrial, and dense urban character contributing local sources under the Santiago basin's persistent inversions. The enclosed Central Valley's near-complete topographic trapping compounds emissions extensively, while La Granja shares the broader Santiago metropolitan air quality challenges throughout most of the year.

When is air pollution at its worst in La Granja?
In La Granja, traffic emissions as well as textile and manufacturing operations are the main local sources, with conditions worsening when temperature inversions set in over the valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. These wind events can carry dust in from the surrounding arid landscape.
Are air quality levels in La Granja 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.
