Gangneung's air quality benefits from its exceptional East Sea Pacific Ocean coastal position in Gangwon-do, with consistent East Sea maritime breezes providing reliable ventilation along the famous Gangneung beach corridor. Vehicle traffic on surrounding roads and the tourism, food culture — Gangneung being famous for its coffee and Chodang tofu — and services corridor contribute modest local sources, while the outstanding coastal exposure generally maintains Gangneung among South Korea's more moderately ventilated eastern coastal cities throughout most of the year.

When is air pollution at its worst in Gangneung?

In Gangneung, traffic emissions as well as tourism-related traffic are the main local sources, with conditions worsening when onshore breezes fall calm. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This natural ventilation is one reason coastal areas often see better readings than inland cities.

Are air quality levels in Gangneung 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.
