What the data includes

The air‑quality record for Sokcho‑si includes six measured pollutants – 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). All of these values come from a single monitoring site in the 금호동 neighbourhood, so the dataset represents one station’s snapshot rather than city‑wide coverage.

Each pollutant shows a single reported value because the minimum, median and maximum are identical: CO is 0.22 ppm, NO₂ is 0.008 ppm, O₃ is 0.0477 ppm, PM10 is 27.0 µg/m³, PM2.5 is 22.0 µg/m³ and SO₂ is 0.0024 ppm. The lack of variation means the current data set does not capture any range or spread for these substances; it only provides a point‑in‑time measurement.

All six readings were last updated on 2026-02-10 18:00 UTC, which falls within the “updated within 7 days” freshness category. Because every pollutant shares the same timestamp and location, the overall dataset is recent but limited to one place and one moment. Consequently, while the figures give a clear picture of conditions at 금호동 at that specific time, they do not reflect possible differences across other parts of Sokcho‑si or over longer periods.
