Yuxi's air quality reflects the Yunnan central plateau's Fuxian Lake basin at 1,640 metres, with vehicle traffic on surrounding expressways and the tobacco — Yuxi being China's largest cigarette production base — and manufacturing corridor contributing distinctive tobacco processing aerosols alongside primary vehicle sources. The elevated plateau position aids dispersal, while the tobacco processing operations' unique organic aerosol signature represents Yuxi's most locally distinctive air quality characteristic throughout most of the year.

When is air pollution at its worst in Yuxi?
Yuxi usually sees its poorest air quality when traffic on the surrounding roads together with textile and manufacturing operations coincide with periods when weather conditions turn unfavourable. 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 Yuxi 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.
