Osorno's air quality reflects the Chilean Los Lagos Region Rahue River valley's partial enclosure at 55 metres, with vehicle traffic on surrounding roads and the dairy, wood processing, and agricultural corridor contributing local sources. Consistent Pacific westerlies provide background ventilation, while the extraordinary residential wood-burning character during the cold wet Chilean Lake District winters generates significant PM2.5 under temperature inversions and Osorno generally maintains moderate to elevated Chilean southern agricultural city readings during the heating season.

When is air pollution at its worst in Rishon LeẔiyyon?
In Rishon LeẔiyyon, traffic on the surrounding roads, agricultural burning, as well as charcoal and wood-burning are the main local sources, with conditions worsening when calm, stagnant conditions settle in the surrounding valley. The bowl-like terrain here limits how quickly pollutants can escape. Fuel burned for winter heating adds an extra layer of particulates on top of other sources.
Are air quality levels in Rishon LeẔiyyon 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.
