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 Kamiyama air‑quality dataset contains 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 名西郡神山町神領字西上角25-4, so the city’s coverage is limited to one station row for each pollutant.
The most recent NO, NO₂ and NOX readings were recorded on 2026‑01‑06 at 01:00 UTC, and they are all flagged as “Old data”. Each of those three gases shows a uniform value of 0.0 ppm for NO and 0.002 ppm for both NO₂ and NOX, with the minimum, median, maximum, 10th percentile and 90th percentile all identical – indicating no observed variation in the recorded period. The PM2.5 measurement is more recent, updated on 2026‑02‑10 at 22:00 UTC and marked “Updated within 3 days”. Its value is consistently 5.0 µg/m³ across all statistical markers, again showing a single static reading.
Because every pollutant is represented by only one row of data, the dataset does not capture spatial or temporal diversity within Kamiyama. The timestamps reveal that three of the four pollutants have not been refreshed for over a month, while PM2.5 offers a comparatively fresh snapshot from early February. With no range of values beyond the single recorded point for each pollutant, the data cannot illustrate fluctuations or trends; it simply reports the exact figure measured at the lone site on the listed dates. Consequently, any assessment of city‑wide air quality should consider that conditions may differ elsewhere and at other times not covered by these limited observations.
