What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only PM2.5 measurements are available, coming from a single monitoring location in 南会津郡南会津町田島字天道沢甲２５４２－７. The most recent reading was recorded at 2026-02-10 22:00 UTC and is still considered fresh, having been updated within the past three days.

Because there is just one row of data, the reported range is extremely narrow: the minimum, median, and maximum values are all identical at 6.0 µg/m³, and the 10th‑ and 90th‑percentile figures match this same number. This uniformity reflects the limited spatial coverage rather than a stable ambient condition; air quality can differ across other parts of Minamiaizu or change over time. With only one sensor and a single pollutant represented, the dataset provides a snapshot rather than a comprehensive view of the city’s overall air quality.
