What the data includes
The dataset for Yeoncheon‑eup contains measurements for six common air pollutants: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or smaller (PM10), particulate matter 2.5 µm or smaller (PM2.5) and sulfur dioxide (SO2). All six pollutant records come from a single monitoring location in the town of 연천, so the station coverage for this city is limited to one site.
Each pollutant has a single reported value that serves as its minimum, median and maximum: CO 0.73 ppm, NO2 0.0161 ppm, O3 0.0023 ppm, PM10 71.0 µg/m³, PM2.5 56.0 µg/m³ and SO2 0.0019 ppm. Because the data rows show identical values across the statistical fields (min, median, max, 10th‑percentile and 90th‑percentile), there is no observed spread or variability within this snapshot.
The most recent update for every pollutant was recorded on 2026‑02‑10 at 18:00 UTC, which falls inside the “updated within 7 days” freshness bucket. This means that, as of today, the newest available measurements are less than a week old, but there are no older or unknown timestamps to compare against. Consequently, while the data is relatively fresh, it represents only one moment in time from a single point source and does not capture spatial differences across Yeoncheon‑eup.
In summary, the city’s air‑quality profile on this page includes six pollutants measured at one station, all reported with identical statistical values and refreshed within the past week. Users should keep in mind that conditions can differ elsewhere in the town or change after the timestamp provided.
