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 dataset for Hashima contains five recent observations drawn from a single monitoring location at 羽島市竹鼻町８６. All five pollutant measurements were recorded at the same timestamp, 2026‑02‑10 22:00 UTC, and each entry is flagged as “Updated within 3 days,” indicating that the newest data are fresh and contemporaneous across the whole set.
The dataset includes readings for nitrogen monoxide (NO), nitrogen dioxide (NO₂), total oxidised nitrogen (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). For NO, NO₂ and NOX the values are identical: a constant 0.009 ppm for each, with no variation between minimum, median or maximum – the spread is effectively zero. SO₂ also shows a uniform reading of 0.0 ppm across its single row. In contrast, PM2.5 displays a single value of 13.0 µg/m³, again without any observed range. Because each pollutant is represented by only one row, the dataset cannot reveal day‑to‑day fluctuations or broader spatial differences within Hashima; it simply reflects the conditions at that specific site and moment.
Overall, the coverage is limited to a single monitoring point, so while the timestamps are recent, the lack of multiple stations means the data do not capture variability across the city. Users should keep in mind that air‑quality conditions can differ by neighbourhood and time of day, and the current figures represent only the snapshot recorded at 羽島市竹鼻町８６ on 2026‑02‑10 22:00 UTC.
