Mun'gyŏng's air quality reflects the Gyeongbuk inland Gyeongcheon River valley's partial enclosure between the Sobaek mountain ranges, with vehicle traffic on surrounding roads and the coal mining legacy, ceramics, and tourism corridor contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the surrounding Sobaek mountain topography creates valley enclosure and the coal mining heritage adds historical environmental context throughout most of the year.

Frequently Asked Questions
Is air quality bad in Mun’gyŏng right now?
On 10 August 2026, overall air quality in Mun’gyŏng is fair. AQI is the main air quality indicator at 26.9/100. Pollution peaks around 2:00 PM (O3: 26.9/100).
Will air quality be worse tomorrow in Mun’gyŏng?
On 11 August 2026, air quality conditions in Mun’gyŏng will be similar to today, with O3 forecast at fair at 33.1/100. Pollution peaks around 11:00 PM (NO2: 42.2/100).
When is air pollution at its worst in Mun’gyŏng?
Pollution in Mun’gyŏng typically rises when vehicle traffic, mining operations, and light manufacturing combine, especially once dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Fuel burned for winter heating adds an extra layer of particulates on top of other sources.
Are air quality levels in Mun’gyŏng 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
