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 Asakura includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All of these come from a single monitoring location at 朝倉市杷木池田483番地1, so the city’s coverage in this snapshot is limited to one station providing five rows of data.
The most recent readings were all recorded on 2026‑02‑10 at 22:00 UTC, which falls within the “updated within three days” freshness window. Because each pollutant has only a single observation, the reported minimum, median and maximum values are identical. NO is measured at 0.002 ppm, NO₂ at 0.007 ppm, NOX at 0.009 ppm, PM2.5 at 7.0 µg/m³ and SO₂ registers as 0.0 ppm. The narrow spread (no variation across the dataset) reflects the limited temporal depth rather than stability of the atmosphere.
With only one sensor contributing data, the picture of Asakura’s air quality is necessarily coarse; conditions can differ across neighborhoods or change throughout the day in ways not captured here. Nonetheless, the available numbers give a baseline snapshot for each pollutant at the time of the last update, and the freshness indicates that the information is recent as of early February 2026.
