Xishan in China reflects the Jiangsu Wuxi metropolitan western Lake Taihu corridor, with vehicle traffic and semiconductor manufacturing and residential character contributing local sources. East China Sea breezes provide limited maritime ventilation, while winter anticyclonic inversions concentrate industrial emissions and the area generally maintains moderate to elevated Yangtze Delta corridor readings throughout most of the year.

When is air pollution at its worst in Xishan?
Xishan usually sees its poorest air quality when vehicle traffic together with manufacturing and food processing coincide with periods when windblown dust events occur. Dust carried on these winds adds substantially to particulate levels. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Xishan 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.
