Air quality today

The air quality today in Eumseong‑gun is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 49.0 µg/m³, while the accompanying PM10 level stands at 61.0 µg/m³ based on 24 valid observations.

Data are shown via OpenAQ and reflect the current monitoring results for this location. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Eumseong‑gun pulls information from four monitoring stations, giving a total of thirty recent observations across the six key pollutants tracked in this city: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM10), fine particulate matter 2.5 µm or smaller (PM2.5) and sulfur dioxide (SO₂). Every pollutant entry shows a last‑updated timestamp of 2026‑02‑10 18:00 UTC, which falls within the “updated within seven days” freshness bucket, so the numbers reflect conditions measured only a few days ago.

Across the pollutants the recorded values span modest ranges. CO varies from a low of 0.34 ppm to a high of 0.58 ppm with a median of 0.51 ppm; NO₂ runs between 0.0086 ppm and 0.0209 ppm, centering around 0.0113 ppm; O₃ is observed from 0.008 ppm up to 0.0356 ppm, with a typical value of 0.0184 ppm. The particulate measurements are higher in absolute terms: PM10 values range from 38 µg/m³ to 61 µg/m³, median 55 µg/m³; PM2.5 spans 28 µg/m³ to 49 µg/m³, median 46 µg/m³. SO₂ is the lowest‑concentration gas, recorded between 0.0019 ppm and 0.0024 ppm with a median of 0.002 ppm.

Because all six pollutants are reported from the same four stations, coverage is uniform in terms of location but the number of observations per pollutant is identical (five recent samples each). The data set shows a tight clustering around the medians for most gases, while the particulate matter values display a slightly broader spread, especially at the upper end of PM10. Although the timestamps are fresh, the limited station count means that conditions can still differ across other parts of Eumseong‑gun not directly monitored by these sensors.
