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 Aikawa includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM₂.5). All of these come from a single monitoring location at 愛甲郡愛川町角田１０４－４, so the city’s air‑quality picture is based on one row of data per pollutant. The most recent reading for each compound was taken on 2026-02-10 22:00 UTC and the source notes that this information was updated within the last three days, indicating a relatively fresh snapshot.
Because there is only one reporting station, the statistical spread for every pollutant is essentially zero. For NO the recorded value is 0.002 ppm, with the minimum, median, 10th percentile and 90th percentile all equal to that figure. NO₂ shows a uniform reading of 0.015 ppm, while NOX is consistently reported at 0.017 ppm. PM₂.5 is measured in micrograms per cubic metre and registers a single value of 8.0 µg/m³ across the board. The lack of variation means that typical or median values are identical to the extremes, providing no insight into day‑to‑day fluctuations.
With only one sensor contributing data, coverage across Aikawa is limited; conditions elsewhere in the city may differ from what this single point records. Nonetheless, the dataset is current, and each pollutant’s most recent measurement is clearly timestamped, offering a concise but narrow view of the local air quality at the time of collection.
