Langfang's air quality reflects the flat North China Plain's Hebei position between Beijing and Tianjin, with vehicle traffic on the G2 expressway and surrounding electronics manufacturing, logistics, and construction contributing local sources. The Beijing-Tianjin-Hebei industrial regional background and winter anticyclonic inversions create some of the region's most severe sustained PM2.5 concentrations, while Langfang's corridor position between China's two largest northern cities amplifies regional pollution transport throughout the year.

When is air pollution at its worst in Langfang?
Air quality in Langfang tends to be worse when road traffic, manufacturing activity, as well as construction dust build up and dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. This is most noticeable during spring and autumn wind events.
Are air quality levels in Langfang 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.
