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 current station data listed for this city is focused on particulate matter (PM). Only one monitoring location contributes to the dataset, and it reports a single pollutant: PM2.5 measured in micrograms per cubic metre. The recorded value is 12.0 µg/m³, observed at 海津市南濃町吉田487 with the most recent timestamp of 2026-02-10 22:00 UTC. This reading falls within a very narrow statistical spread—the minimum, median, maximum and both the 10th and 90th percentiles are all identical at 12.0 µg/m³—indicating that only one data point is available rather than a distribution of measurements.
Because there is just a single row, coverage across the city is limited to this specific site, and no additional pollutants or stations are represented in the OpenAQ feed for Kaizu. The timestamp is recent enough to be classified as updated within three days, but the overall dataset lacks depth; variations over time or space cannot be assessed from the present information. Consequently, while the available figure is current, it provides only a snapshot of conditions at one location and does not capture broader city‑wide air quality dynamics.

Data notes
The current reading for Kaizu is based on a single valid measurement and was refreshed recently, with data updated within 3 days (last update: 2026‑02‑10 22:00 UTC). This snapshot reflects conditions at the time of that measurement; air quality can differ across neighborhoods and change throughout the day, so values may vary locally and over short periods.
