What the data includes

The dataset for Changnyeong‑gun contains six rows of observations drawn from a single monitoring site in 창녕읍. All six pollutants tracked by the OpenAQ network are represented: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µm (PM2.5) and sulfur dioxide (SO₂). Each pollutant has a single reported value, which also serves as the minimum, median and maximum for that location because only one measurement is available per parameter.

All six readings were last updated on 2026‑02‑10 at 17:00 UTC, placing them well within the “updated within 7 days” freshness category. Because there is just one monitoring station, the data reflects conditions at that specific point rather than a broader spatial picture of the county. The reported concentrations are consistent across the dataset: CO is 0.35 ppm, NO₂ is 0.0188 ppm, O₃ is 0.0134 ppm, PM10 is 27.0 µg/m³, PM2.5 is 19.0 µg/m³ and SO₂ is 0.0029 ppm. The lack of variation (identical min‑median‑max values) means the dataset cannot show any range or spread for these pollutants.

Given the single‑site coverage and the uniform timestamps, the information provides a snapshot of air quality at one moment in 창녕읍 but does not capture temporal changes or differences across other parts of Changnyeong‑gun. Users should keep in mind that conditions can differ elsewhere and at other times, so this data represents only the most recent measurement from the lone reporting location.
