Quilpué's air quality reflects the Valparaíso metropolitan area's inland valley position at 148 metres, with vehicle traffic on surrounding roads and the residential and services corridor contributing local sources. The coastal Cordillera partially blocks Pacific maritime ventilation, while the valley's topographic enclosure creates concentration under winter inversions and Quilpué generally maintains moderate to elevated Valparaíso metropolitan inland valley readings throughout the winter months.

When is air pollution at its worst in Quilpué?

Quilpué usually sees its poorest air quality when traffic emissions coincides with periods when temperature inversions set in over the valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.

Are air quality levels in Quilpué 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.
