Punta Arenas's air quality benefits from its extraordinary Strait of Magellan position in Chilean Patagonia, with consistent and often violent Southern Ocean westerlies providing among the world's most powerful natural urban ventilation. Vehicle traffic on surrounding roads and the petroleum, government, and Antarctic tourism corridor contribute modest local sources, while the extraordinary Southern Ocean wind exposure effectively disperses most local emissions and Punta Arenas generally maintains among the Southern Hemisphere's cleanest major city environments throughout most of the year.

When is air pollution at its worst in Punta Arenas?
In Punta Arenas, traffic emissions together with tourism-related traffic are the main local sources, with conditions worsening when winds are light and dispersion is poor. Background emissions and local weather both shape how conditions change from day to day. Background emissions and local weather both play a role in day-to-day changes.
Are air quality levels in Punta Arenas 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
