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 feed for Minamiashigara currently includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All data come from a single monitoring site at 南足柄市生駒３３０－１, so the city’s coverage consists of one station providing five rows of observations.
Each pollutant shows an identical narrow range because only one value has been recorded: NO is 0.001 ppm, NO₂ is 0.005 ppm, NOX is 0.006 ppm, PM2.5 is 3.0 µg/m³ and SO₂ is 0.001 ppm. The minimum, median and maximum for every metric are the same, indicating no variation in the recent sample set. The most recent update for all five parameters was recorded on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within three days” freshness bucket.
Because the dataset relies on a single location, it does not capture spatial differences that may exist across Minamiashigara, and the lack of multiple readings means trends or day‑to‑day changes cannot be assessed from this snapshot. Nonetheless, the information is current to within a few days, giving a recent point‑in‑time picture of the city’s air composition at the monitoring site.
