Temuco's air quality reflects the Chilean Araucanía Cautín River valley's partial topographic enclosure, with vehicle traffic on surrounding roads and the wood-burning residential heating — Temuco having some of Chile's highest wood fuel consumption — generating severe winter PM2.5 under frequent temperature inversions. The surrounding Andean and Coastal Range topography creates significant enclosure, while the extraordinary residential wood-burning character makes Temuco one of Chile's most persistently wood smoke-challenged urban environments throughout the winter months.

When is air pollution at its worst in Temuco?
In Temuco, vehicle traffic along with wood-burning stoves are the main local sources, with conditions worsening when the surrounding valley traps air close to the ground. 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 Temuco 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.
