Air quality today
The air quality in Jangseong‑gun is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 22.0 µg/m³ and a PM10 level of 27.0 µg/m³, based on six valid observations.
Data is shown via OpenAQ. 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 Jangseong‑gun dataset currently contains six individual measurement rows, each reporting the same set of six 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 rows come from the monitoring site in 장성읍, and every pollutant reading was last updated on 2026‑02‑10 at 17:00 UTC, which falls within the “updated within 7 days” freshness category.
Because each pollutant has only a single recorded value, the minimum, median and maximum are identical for every metric. CO is reported as 0.34 ppm, NO₂ as 0.013 ppm, O₃ as 0.0016 ppm, PM10 as 27.0 µg/m³, PM2.5 as 22.0 µg/m³ and SO₂ as 0.0025 ppm. The lack of variation means there is no observable spread or range across the data points; each pollutant’s distribution consists of a single point measurement.
The coverage is therefore limited to one location and one recent timestamp per pollutant, with no older or unknown entries in the record. While this provides an up‑to‑date snapshot for 장성읍, it does not capture spatial differences across Jangseong‑gun or temporal changes beyond the most recent reading. Users should keep in mind that air quality can differ by area and time, and the current dataset reflects only the conditions measured at a single site on a specific date.
