El Bosque's air quality reflects the Santiago metropolitan area's southern residential corridor at 520 metres in the Central Valley, with vehicle traffic on surrounding roads and the dense urban residential 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 El Bosque shares the broader Santiago metropolitan air quality challenges throughout most of the year.

When is air pollution at its worst in El Bosque?

Pollution in El Bosque typically rises when vehicle traffic, especially once calm, stagnant conditions settle in the surrounding valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. This is most pronounced in winter, when inversions are more frequent.

Are air quality levels in El Bosque 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.
