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, reporting a single pollutant: PM2.5 measured in micrograms per cubic metre. The recorded value is 23.0 µg/m³, taken at 丸亀市大手町２－３－１ and timestamped 2026-02-10 22:00 UTC. This entry falls within the “last three days” freshness bucket, meaning the most recent measurement is relatively current.
Because the dataset contains just a single row, there is no range of values to compare across different sites or times; the minimum, median, and maximum are all identical at 23.0 µg/m³. Consequently, any assessment of variability or broader spatial coverage cannot be made from this limited sample. Users should keep in mind that air quality can differ throughout Marugame, and the available figure reflects only one point in time and location rather than a city‑wide average.
