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 row is available for Bloomington, Indiana, and it reports a single pollutant: PM2.5 measured in micrograms per cubic metre. The recorded concentration is 29.5 µg/m³, coming from the “Bloomington – Binfor” sensor and last refreshed on 2026-02-10 23:00 UTC. This timestamp falls within the past seven days, indicating that the most recent reading is relatively fresh.
Because the dataset contains just a single row, there is no variation in values to describe; the minimum, median, maximum, 10th percentile and 90th percentile are all identical at 29.5 µg/m³. No other pollutants such as ozone or nitrogen dioxide appear in the current listings, so coverage across different air‑quality metrics is limited. With only one recent measurement, the data cannot capture spatial differences within Bloomington, and conditions may differ elsewhere or change after the last update.
