Puerto Montt's air quality reflects the Chilean Los Lagos Region Reloncaví Bay coastal position, with vehicle traffic on surrounding roads and the extraordinary residential wood-burning heating — Puerto Montt having some of Chile's highest wood fuel consumption — generating severe winter PM2.5 under frequent temperature inversions. Consistent Pacific westerlies and the fjord system's maritime influence provide seasonal relief, while the wood-burning character makes Puerto Montt one of Chile's most persistently wood smoke-challenged urban environments throughout the winter months.

Are air quality levels in Puerto Montt 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.
