What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only PM2.5 measurements are available from a single monitoring location, identified as Cottage Grove City S. The most recent reading was recorded on 2026-02-10 23:00 UTC and the dataset is considered up‑to‑date within the past seven days.
With just one row of data, the reported values show no variation: the minimum, median, and maximum all equal 5.9 µg/m³, and both the 10th and 90th percentiles match this figure as well. Because there is only a single monitoring point, the coverage across Cottage Grove is limited to that specific site, so conditions elsewhere in the city may differ. The freshness of the timestamp indicates the data is recent, but the lack of additional stations means broader spatial trends cannot be assessed from this dataset alone.
