The air quality in Jeongseon‑eup is currently classified as Moderate. The main pollutant identified is PM2.5, fine particulate matter that contributes to the overall rating. Measurements show a PM2.5 concentration of 25.0 µg/m³ and a PM10 level of 34.0 µg/m³ based on six valid observations collected through OpenAQ.
These values reflect the present conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 Jeongseon‑eup air quality dataset currently contains measurements for six key pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), fine particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). Each pollutant is represented by a single observation row, so the dataset comprises six rows in total, one per contaminant.
All six observations were recorded at the same monitoring location in 정선읍 and share an identical timestamp of 2026‑02‑10 17:00 UTC. The system flags each entry as “Updated within 7 days,” indicating that the most recent data are less than a week old. Because every pollutant has only one reported value, the statistical summary shows no variation: the minimum, median, maximum, 10th percentile and 90th percentile are all identical for each metric. CO is listed at 0.34 ppm, NO₂ at 0.0111 ppm, O₃ at 0.0422 ppm, PM₁₀ at 34.0 µg/m³, PM₂.₅ at 25.0 µg/m³ and SO₂ at 0.0017 ppm.
The uniformity of timestamps means the dataset provides a snapshot rather than a time series, so it cannot illustrate short‑term fluctuations or longer trends for Jeongseon‑eup. With only one monitoring site contributing data, spatial coverage across the town is limited; conditions elsewhere may differ from those captured at this single point. Nonetheless, the current record offers a complete set of the six standard pollutants, all refreshed within the past week, giving users an up‑to‑date but momentary view of air quality in Jeongseon‑eup.
