Air quality today
The air quality today in Goesan‑eup is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 37.0 µg/m³, while the accompanying PM10 level stands at 48.0 µg/m³ based on six valid observations.
Data are shown via OpenAQ and reflect the current monitoring results for this location. 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 air‑quality record for Goesan‑eup consists of a single monitoring station that reports six common 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 of the latest observations were uploaded on 2026‑02‑10 at 18:00 UTC, so the data are fresh within the past week for every pollutant.
For each gas the measured value is identical across its minimum, median and maximum, indicating that only one reading is currently available. CO registers at 0.52 ppm, NO₂ at 0.0246 ppm, O₃ at 0.0053 ppm and SO₂ at 0.0029 ppm. The particulate measurements show PM10 at 48.0 µg/m³ and PM2.5 at 37.0 µg/m³, again with no variation among the reported statistics. Because there is just one row of data per pollutant, the spread (p10‑p90) is zero, so no range can be derived from multiple observations.
The dataset therefore provides a complete but very limited snapshot: coverage includes all six pollutants, yet only a single location and a single timestamp contribute to each metric. This means that while the numbers are up‑to‑date, they represent conditions at one point in time and may not capture spatial or temporal fluctuations across Goesan‑eup. Users should keep in mind that air quality can differ elsewhere in the town or change later in the day, even though the current record is recent and fully populated for each listed pollutant.

Data notes
The data shown reflects six valid measurements and is updated within three days, with the most recent reading recorded on 2026‑02‑10 at 18:00 UTC. This snapshot provides a current view of air quality in Goesan-eup, but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured by these figures.
