What the data includes

The dataset for Geumsan‑gun includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). All values come from twelve recent rows recorded at a single monitoring location in 금산읍, and each pollutant’s most recent reading was logged on 2026‑02‑10 18:00 UTC, which falls within the “updated within 7 days” freshness window.

Across the pollutants the observed ranges are modest. CO varies from 0.32 to 0.56 ppm with a median of 0.44 ppm; NO₂ spans 0.0103–0.0152 ppm (median 0.0128 ppm); O₃ is recorded between 0.0108 and 0.0218 ppm (median 0.0163 ppm). The particulate matter measurements are higher in absolute terms: PM10 ranges from 22 to 35 µg/m³ (median 28.5 µg/m³) and PM2.5 from 18 to 33 µg/m³ (median 25.5 µg/m³). SO₂ shows the lowest concentrations, from 0.0022 to 0.0042 ppm (median 0.0032 ppm).

Because all twelve rows are recent and come from a single site, the data give a snapshot of current air quality at that location but do not capture spatial variation across Geumsan‑gun. The spread between minimum and maximum values is relatively narrow for gases, while particulate matter shows a broader distribution, indicating more variability in dust‑related conditions. Users should keep in mind that conditions can differ elsewhere in the county or at other times, as the dataset reflects only this one monitoring point on the most recent date.

Data notes

The data shown reflects six valid measurements and is updated within 3 days, with the latest values recorded at 2026‑02‑10T18:00:00+00:00. These readings provide a snapshot of current conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
