Hamhŭng's air quality reflects the flat North Korean eastern coastal position on the Sea of Japan, with vehicle traffic and the chemical — Hamhung being North Korea's chemical industrial capital — and manufacturing corridor generating elevated industrial SO₂ and PM2.5. The Sea of Japan provides limited maritime ventilation, while the extraordinary chemical industrial scale and winter coal heating make Hamhung North Korea's most distinctively chemical industrial-defined coastal environment.

When is air pollution at its worst in Hamhŭng?
In Hamhŭng, road traffic, petrochemical and refining operations, and manufacturing and food processing are the main local sources, with conditions worsening when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Hamhŭng 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.
