What the data includes

The Cheongsong‑eup air‑quality feed contains data for six common pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂, reported as NO2), ozone (O₃, reported as O3), particulate matter 10 µm or less (PM10), fine particulate matter 2.5 µm or less (PM2.5, reported as PM25) and sulfur dioxide (SO₂). Each pollutant is represented by a single measurement row, so the dataset comprises six rows in total, one for each substance.

All of the values were last updated on 2026‑02‑10 at 17:00 UTC, which means the freshest data are less than a week old and fall into the “updated within 7 days” category. The reported concentrations are identical across the minimum, median and maximum statistics, indicating that each pollutant currently has only one recorded value for Cheongsong‑eup. CO is measured at 0.27 ppm, NO₂ at 0.0124 ppm, O₃ at 0.0218 ppm, PM10 at 27.0 µg/m³, PM2.5 at 26.0 µg/m³ and SO₂ at 0.0023 ppm.

Because the dataset consists of a single recent snapshot per pollutant, there is no observable spread or trend within this location; the range for every substance collapses to a single point. The uniform freshness across all six pollutants shows consistent reporting timing, but the limited number of rows means that temporal variation and spatial differences within Cheongsong‑eup cannot be captured from these data alone. Users should keep in mind that conditions may change throughout the day or differ between neighborhoods, even though the current feed provides only this one set of values.
