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 Fujinomiya data set contains five pollutant measurements collected from a single monitoring location (富士宮市弓沢町１５０). The available pollutants are nitrogen monoxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). Each of the five rows was last updated on 2026-02-10 22:00 UTC, which falls within the “updated within three days” freshness window, so the information reflects very recent conditions for this site.
Across all pollutants the recorded values are identical at the single station, showing no variation in the data stream. NO is reported as 0.0 ppm, while both NO₂ and NOX register 0.009 ppm. PM2.5 measures a constant 5.0 µg/m³, and SO₂ is listed at 0.001 ppm. Because each pollutant has only one recorded value, the minimum, median, maximum, as well as the 10th‑percentile and 90th‑percentile figures are all the same. This uniformity means there is no observable spread or range for any of the measured substances in Fujinomiya at present.
The dataset’s coverage is limited to a single monitoring point, so it cannot capture spatial differences that may exist across other neighborhoods or districts within the city. While the timestamps are fresh, the lack of multiple stations and the absence of historical records beyond this most recent entry restrict the ability to assess temporal trends or compare conditions over time. Users should keep in mind that air quality can vary by location and moment, and the current snapshot represents only one point measurement for Fujinomiya.
