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 Minami‑Alps includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), total nitrogen oxides (NOX) and fine particulate matter (PM2.5). All observations come from a single monitoring site at 南アルプス市鏡中條１６４２－２, so the city’s air‑quality picture is based on one row of data for each pollutant. The most recent readings were recorded on 2026‑02‑10 at 22:00 UTC, which is within three days of today (2026‑02‑13), indicating that the available values are relatively fresh.
Each pollutant shows a single reported value with no variation across the dataset. NO was measured at 0.001 ppm, NO₂ at 0.018 ppm and NOX at 0.019 ppm; for PM2.5 the concentration is 10.0 µg/m³. Because the minimum, median, and maximum are identical for every pollutant, there is no observable spread or range in the data. This uniformity reflects the limited spatial coverage – only one sensor location – rather than a stable city‑wide condition.
In practical terms, the current snapshot provides a concise but narrow view of Minami‑Alps’ air quality. With just one monitoring point, variations that might exist across different neighborhoods or over longer periods are not captured. Users should keep in mind that conditions can differ by location and time, and additional measurements would be needed for a fuller understanding of the city’s overall atmospheric environment.

Data notes
The data shown reflect four valid measurements and were updated within 3 days, with the latest reading recorded at 2026‑02‑10T22:00:00+00:00. This snapshot provides a current view of air quality in Minami‑Alps, but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured by these figures.
