What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only a single monitoring row is available, and it reports PM2.5 concentrations measured in micrograms per cubic metre. The most recent reading was recorded at 2026-02-10 22:00 UTC, which places the data within the last three days, satisfying the “fresh” criterion for this location.

All reported values are identical across statistical measures: the minimum, median, and maximum PM2.5 concentration is 24.0 µg/m³, with both the 10th and 90th percentiles also at 24.0 µg/m³. Because there is just one data point, there is no observed spread or variation in the measurements, and coverage is limited to a single site at 今治市旭町1-4-9. Consequently, while the figure gives an up‑to‑date snapshot for that spot, it does not capture spatial differences across Imabari, and conditions elsewhere in the city may differ from this singular reading.
