Sokcho's air quality benefits from its exceptional Gangwon-do East Sea Pacific Ocean coastal position adjacent to Seoraksan National Park, with consistent East Sea maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the tourism, crab fishing, and services corridor contribute modest local sources, while the outstanding coastal exposure and the extraordinary Seoraksan granite mountain backdrop create dramatic topographic variation and Sokcho generally maintains among South Korea's cleaner major coastal resort city environments throughout most of the year.

When is air pollution at its worst in Sokcho?
The biggest local contributors to pollution in Sokcho are traffic emissions, fishing fleet activity, as well as seasonal tourism traffic, particularly once maritime winds die down. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Sokcho 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.
