Xichang's air quality reflects the Sichuan Anning River valley's partial enclosure at 1,500 metres adjacent to the CASC Xichang Satellite Launch Center, with vehicle traffic and the satellite launch operations, tourism, and agricultural corridor contributing local sources. The surrounding Liangshan Mountains create topographic variation and the satellite launch operations' distinctive rocket propulsion emissions represent Xichang's most internationally unique air quality contribution throughout most of the year.

When is air pollution at its worst in Xichang?

Xichang usually sees its poorest air quality when traffic emissions, crop farming, and tourism-related traffic coincide with periods when weather conditions turn unfavourable. Day-to-day conditions here depend heavily on the weather. Background emissions and local weather both play a role in day-to-day changes.

Are air quality levels in Xichang 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.
