Air quality today
The air quality in Sangju‑si is currently rated as Moderate. The main pollutant identified is PM2.5, with a measured concentration of 31.0 µg/m³. Additional monitoring shows a PM10 level of 35.0 µg/m³ based on six valid observations.
Data are shown via OpenAQ and reflect the latest available readings for the city. 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 dataset for Sangju‑si contains measurements from a single monitoring site that reports six common air‑quality gases and particles: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). Each pollutant is represented by one row, so the total number of rows equals six.
All six observations were last refreshed on 2026‑02‑10 at 18:00 UTC, which falls within the “updated within 7 days” freshness category. Because there is only one station, every pollutant shares the same timestamp and the same recency; no older or unknown timestamps appear in the record.
The values are uniform across each metric: CO is recorded at 0.35 ppm, NO₂ at 0.0064 ppm, O₃ at 0.027 ppm, PM₁₀ at 35.0 µg/m³, PM₂.5 at 31.0 µg/m³ and SO₂ at 0.0027 ppm. For every pollutant the minimum, median and maximum are identical, indicating that only a single measurement is available rather than a range of observations over time.
Because coverage relies on just one monitoring location, the data give a snapshot of conditions at that point but do not capture spatial variation across Sangju‑si. The freshness of the latest reading is good, yet the lack of multiple stations or repeated measurements means the dataset cannot describe how air quality may differ in other neighborhoods or change throughout the day.
