This assessment reflects the latest available data for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 Fujiidera contains a single monitoring location at 藤井寺市岡１－１－１, so all reported values come from one row. Four pollutants are recorded: nitrogen monoxide (NO) at 0.001 ppm, nitrogen dioxide (NO₂) at 0.015 ppm, total nitrogen oxides (NOX) at 0.016 ppm, and fine particulate matter (PM2.5) at 12.0 µg/m³. Each of these measurements was last updated on 2026-02-10 22:00 UTC, which means the freshest data are just a few days old.
Because there is only one station, the range for every pollutant collapses to a single value; the minimum, median, and maximum are identical (NO 0.001 ppm, NO₂ 0.015 ppm, NOX 0.016 ppm, PM2.5 12.0 µg/m³). This lack of spread indicates that the dataset cannot show variability across different parts of the city or over time beyond the most recent snapshot. The freshness flag shows all entries are “Updated within 3 days,” so while the data are current, they represent a very limited spatial picture.
In practical terms, Fujiidera’s air‑quality reporting currently offers only one point of reference for each pollutant, with no historical depth or broader coverage to capture fluctuations that might occur elsewhere in the city. Users should keep in mind that conditions can differ by neighborhood and time of day, even though the available numbers are up‑to‑date as of early February 2026.

Data notes
The data shown are based on four valid measurements and were refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC (updated within 3 days). These values represent a snapshot of ambient conditions across Fujiidera; actual air quality can differ by specific neighbourhoods and times of day, so local variations may not be captured in this summary.
