Sizhan in China reflects the flat North China Plain's agricultural and urban corridor position, with vehicle traffic and manufacturing contributing local sources. Winter residential coal heating generates elevated PM2.5 under inversions and the regional industrial background elevates winter readings throughout the year.

When is air pollution at its worst in Sizhan?
Pollution in Sizhan typically rises when vehicle traffic, textile and manufacturing operations, and agricultural activity combine, especially once dry spells bring strong winds. These wind events can carry dust in from the surrounding arid landscape. Fuel burned for winter heating adds an extra layer of particulates on top of other sources.
Are air quality levels in Sizhan 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.
