Weifang's air quality reflects the flat Shandong central plain's agricultural and industrial position, with vehicle traffic on surrounding expressways and the kite manufacturing, chemical, and agricultural corridor contributing local sources. Winter residential coal and industrial heating generates elevated PM2.5 under frequent inversions, while the flat terrain allows reasonable summer dispersal and the North China Plain's regional industrial background elevates winter readings, generally maintaining moderate to above-average Shandong central readings throughout the year.

When is air pollution at its worst in Weifang?
Weifang usually sees its poorest air quality when road traffic, petrochemical and refining operations, as well as light manufacturing coincide with periods when dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Coal and wood used for winter heating add substantially to particulate levels.
Are air quality levels in Weifang 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.
