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 data set for Sunchang‑eup includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). All values come from a single monitoring station, so the coverage is limited to one location within the town.
Each pollutant has a single recorded value that also serves as its minimum, median and maximum for the period covered. CO is reported at 0.31 ppm, NO₂ at 0.0143 ppm, O₃ at 0.0014 ppm, PM₁₀ at 31.0 µg/m³, PM₂.₅ at 27.0 µg/m³ and SO₂ at 0.0025 ppm. Because there is only one row per pollutant, the data show no spread – the 10th‑percentile and 90th‑percentile values are identical to the median.
The most recent update for every pollutant was recorded on 2026‑02‑10 at 18:00 UTC, which places all measurements comfortably within the “updated within 7 days” freshness bucket. This indicates that the latest snapshot is current, but the lack of historical rows means trends or variability over time cannot be assessed from this source.
Overall, the dataset provides a very narrow view of air quality in Sunchang‑eup: one station delivering a single recent reading for each of six pollutants, with no additional temporal depth or spatial distribution. Users should keep in mind that conditions can differ across neighborhoods and throughout the day, even though the available numbers are up‑to‑date as of the timestamp given.
