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 Higashi Hiroshima includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All of these come from a single monitoring site located at 東広島市西条中央２丁目１５－１, so the city’s coverage in this snapshot is limited to one station per pollutant. The most recent reading for each compound was recorded on 2026‑02‑10 22:00 UTC, which falls within the “updated within three days” freshness window indicated by the source.
Across the five pollutants the reported values show no variation: NO registers exactly 0.002 ppm, NO₂ 0.018 ppm, NOX 0.020 ppm, SO₂ 0.001 ppm and PM2.5 18.0 µg/m³, with each metric’s minimum, median and maximum all equal to the same figure. This uniformity means there is no observable spread or range for any of the substances in the current data batch. Because only one location contributes, the dataset cannot capture spatial differences that may exist elsewhere in Higashi Hiroshima, and the single‑time snapshot does not reveal temporal trends beyond the most recent update.
In summary, the city’s air‑quality profile here is based on a solitary monitoring point, offering fresh data as of early February 2026 but providing only a narrow view of pollutant levels—each reported at a single fixed concentration with no internal variability.
