Dandong's air quality reflects the Liaoning Yalu River border position with North Korea, with vehicle traffic on surrounding roads and the port, textile, and trade corridor contributing local sources. The Yellow Sea and Yalu River maritime influence provides limited coastal ventilation, while transboundary industrial emissions from North Korea's Sinuiju industrial corridor on northeasterly winds represent a distinctive cross-border air quality influence and winter coal heating adds seasonal PM2.5 throughout the year.

When is air pollution at its worst in Dandong?
Pollution in Dandong typically rises when traffic emissions together with manufacturing activity combine, especially once windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Dandong 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.
