What the data includes

The Kamagaya air‑quality feed currently includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM₂.5). All of these values come from a single monitoring location identified as 鎌ケ谷市軽井沢2060-32, so the dataset represents one station with four separate pollutant rows.

Each pollutant shows a single recorded value that is also its minimum, median and maximum for the reporting period. NO registers at 0.003 ppm, NO₂ at 0.029 ppm, NOX at 0.032 ppm and PM₂.5 at 19.0 µg/m³. Because there is only one observation per pollutant, there is no spread or variability to report; the data set therefore provides a snapshot rather than a range of conditions.

The most recent timestamp for every measurement is 2026‑02‑10 22:00 UTC, and each entry notes that it was “Updated within 3 days.” This indicates that the latest available data are only a few days old, but because there are no older or unknown‑date rows in the file, the overall freshness of the dataset is uniformly recent. With just one monitoring site, the coverage for Kamagaya is limited; conditions can differ across neighborhoods and times of day, so this single point should be interpreted as a representative sample rather than a complete picture of citywide air quality.

Data notes

The data shown reflects four valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is classified as Updated within 3 days. While these figures give a reliable snapshot of Kamagaya’s air quality at that moment, conditions can differ across neighborhoods and change throughout the day, so local variations may exist.
