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 Inazawa contains a single monitoring location – 稲沢市稲府町1 – and provides measurements for four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All four variables are reported in the same unit set, with NO at 0.017 ppm, NO₂ at 0.018 ppm, NOX at 0.035 ppm and PM2.5 at 10.0 µg/m³. For each pollutant the minimum, median and maximum values are identical, indicating that only one reading is currently available for every metric.
The most recent data timestamp is 2026‑02‑10 22:00 UTC, which falls within the “updated within 3 days” freshness bucket used by OpenAQ. Because there is just one row in the table, the overall coverage across the city is limited to this single site; no additional stations contribute alternative readings or temporal depth. Consequently, the reported values represent a snapshot rather than a range of conditions throughout Inazawa.
Given the single‑point nature of the record, the dataset shows no variability: each pollutant’s spread (difference between minimum and maximum) is zero, and the 10th and 90th percentiles match the recorded value. This lack of dispersion means that any assessment of city‑wide air quality must consider the possibility of spatial differences that are not captured here. While the data are fresh, the limited station count restricts insight into how pollutant levels might differ across neighborhoods or over longer periods.
