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 air‑quality feed for Minano includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5) – all reported from a single monitoring location at 秩父郡皆野町皆野1420-1. In total the dataset contains four rows, one for each pollutant, and every row was last refreshed on 2026‑02‑10 22:00 UTC, which falls within the “updated within three days” window, so the information is current.
All four pollutants show a single recorded value with no observed variation across the sampling period. NO registers at 0.001 ppm, NO₂ at 0.009 ppm and NOX at 0.010 ppm; each of these gases has identical minimum, median and maximum readings, indicating an extremely narrow range (essentially a point measurement). PM2.5 is reported as 6.0 µg/m³, again with the same figure appearing as the minimum, median and maximum. Because there is only one monitoring site, the dataset does not capture spatial differences within Minano, and the lack of multiple observations means no spread or trend can be derived from these numbers.
Overall the data set offers a complete snapshot for each listed pollutant at a single point in time, but it provides limited insight into broader city‑wide conditions. The freshness of the timestamps is good, yet the coverage is modest – only one station contributes all four rows – and the uniform values suggest that any variability across neighborhoods or over longer periods would not be reflected here. Users should keep in mind that air quality can change with location and time, even though the current feed presents a concise, up‑to‑date picture for Minano’s sole monitoring point.
