What the data includes

The dataset for Yeongdong‑gun pulls in measurements from three monitoring sites, giving a total of twenty‑four recent rows of data. All six pollutants—carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulfur dioxide (SO₂)—are represented, and the most recent timestamp for each is 2026‑02‑10 17:00 UTC, which falls within the last seven days.

Across the records the gas concentrations show relatively narrow ranges. CO varies from a low of 0.30 ppm to a high of 0.41 ppm with a median of 0.37 ppm; NO₂ spans 0.0057‑0.0163 ppm, median 0.011 ppm; O₃ runs between 0.004 and 0.0434 ppm, median 0.0207 ppm; SO₂ is measured from 0.0019 to 0.0023 ppm, median 0.0022 ppm. The particulate matter figures are higher in absolute terms and display a broader spread: PM10 ranges from 30 µg/m³ to 43 µg/m³ with a median of 32.5 µg/m³, while PM2.5 varies between 16 µg/m³ and 30 µg/m³, median 27.5 µg/m³.

All pollutant values come from the same sub‑area, 황간면, so spatial coverage is limited to that location within the county. Nevertheless, the data are fresh, with every parameter updated on the same recent date, and the number of rows (twenty‑four) provides a modest sample size for each contaminant. Because measurements are confined to one site, conditions elsewhere in Yeongdong‑gun may differ from those captured here.
