Air quality today
The air quality today in Gongju‑si is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 41.0 µg/m³, while PM10 stands at 59.0 µg/m³ based on six valid observations.
These values are presented through OpenAQ data. 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 Gongju‑si currently draws from a single monitoring site in 탄천면, providing one recent reading for each of the six standard air‑quality pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulfur dioxide (SO₂). All six observations were recorded at the same moment – 2026‑02‑10 18:00 UTC – and are flagged as having been updated within the past seven days, so the information reflects a very recent snapshot of conditions at that location.
Because there is only one reporting station, each pollutant appears just once in the table. Consequently the statistical summary for every compound shows identical minimum, median and maximum values, with no observable spread (for example, CO registers 0.57 ppm, NO₂ 0.0192 ppm, O₃ 0.0047 ppm, PM10 59 µg/m³, PM2.5 41 µg/m³ and SO₂ 0.0041 ppm). This uniformity indicates that the dataset does not capture variability across different parts of Gongju‑si or over time; it simply records the state of the air at a single point in space and moment.
In practical terms, users can rely on the freshness of these six measurements but should be aware that they represent only one location’s conditions. Spatial differences within the city or changes after the timestamp are not reflected here, so any interpretation of overall city‑wide air quality would need additional data sources or more extensive monitoring coverage.

Data notes
The data shown reflects six valid measurements and is updated within 3 days, with the most recent reading recorded at 2026‑02‑10T18:00:00+00:00. These values represent a snapshot of ambient conditions across Gongju‑si; actual air quality can differ by specific location and time of day within the city, so users should consider local variations when interpreting the information.
