Guyuan's air quality reflects the Ningxia-Gansu Liupan Mountain Loess Plateau highland at 1,753 metres, with vehicle traffic on surrounding roads and the agricultural, traditional herbal medicine, and light manufacturing corridor contributing local sources. Windblown loess plateau dust generates elevated PM10 during dry windy periods, while the elevated plateau position aids summer dispersal and the relatively low industrial density generally maintains moderate northwestern China Loess Plateau highland readings throughout most of the year.

When is air pollution at its worst in Guyuan?
The biggest local contributors to pollution in Guyuan are road traffic, light manufacturing, along with crop farming, particularly once dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Such events are most common in the drier shoulder seasons.
Are air quality levels in Guyuan 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.
