Pongnam in Gyeonggi reflects the flat South Korean Gyeonggi-do agricultural and suburban corridor, with vehicle traffic on surrounding roads and light manufacturing and residential operations contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the broader Seoul metropolitan regional background maintains moderate South Korean Gyeonggi provincial corridor readings throughout most of the year.

When is air pollution at its worst in Pongnam?

The biggest local contributors to pollution in Pongnam are traffic on the surrounding roads, manufacturing activity, as well as crop farming, particularly once dry, windy weather picks up. These wind events can carry dust in from the surrounding arid landscape. Such events are most common in the drier shoulder seasons.

Are air quality levels in Pongnam 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.
