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 Naju‑si currently contains six individual measurement rows, each reporting the same set of 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 six rows are from the same monitoring location, 빛가람동, and each pollutant has a single recorded value that serves as its minimum, median and maximum for the period covered. The most recent update across all pollutants was logged on 2026‑02‑10 18:00 UTC, which falls within the “updated within 7 days” freshness category, indicating that the data are relatively current.
Because every pollutant shows identical statistics—CO at 0.23 ppm, NO₂ at 0.0114 ppm, O₃ at 0.0183 ppm, PM10 at 29.0 µg/m³, PM2.5 at 28.0 µg/m³ and SO₂ at 0.0029 ppm—the dataset does not reveal any variation over time or across different sites within the city. The lack of multiple stations means spatial coverage is limited to a single neighborhood, so conditions elsewhere in Naju‑si may differ from those captured here. Likewise, with only one timestamp per pollutant, there is no observable spread or trend; the reported values represent a snapshot rather than a range of daily fluctuations.
In summary, the available data provide a concise picture of six key air quality indicators for one location in Naju‑si, all refreshed within the past week. Users should keep in mind that broader city‑wide conditions could vary, and additional monitoring points would be needed to capture such diversity.
