Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The air‑quality feed for Sancheong‑gun 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 location in the town of 산청읍, so the dataset represents one station rather than a network spread across the county.
Each pollutant has a single recent observation recorded at 2026‑02‑10 17:00 UTC, which falls within the “updated within 7 days” freshness category. Because there is only one reading per pollutant, the reported minimum, median and maximum are identical for every metric: CO is 0.26 ppm, NO₂ is 0.0096 ppm, O₃ is 0.0139 ppm, PM10 is 16.0 µg/m³, PM2.5 is 10.0 µg/m³ and SO₂ is 0.0024 ppm. This lack of variation means the data cannot show any range or trend for the current conditions.
With just one monitoring site, coverage across Sancheong‑gun is limited; spatial differences in air quality are not captured by this dataset. The timestamps indicate that the information is fresh as of early February 2026, but because there are no older or additional rows, the picture of how pollutant levels change over time remains incomplete. Users should keep in mind that conditions can differ elsewhere in the county and at other times, even though the available numbers provide a snapshot of the latest measured values at 산청읍.
