What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only one monitoring site contributes to the record, providing two rows of recent observations that cover PM10 and PM2.5. Both pollutants have a single reported value: PM10 measured at 33.0 µg/m³ and PM2.5 at 16.0 µg/m³, each with identical minimum, median and maximum figures, indicating no variation in the limited sample. The most recent timestamps for both metrics are from 2026-02-10 13:00 UTC, which falls within the three‑day freshness window used by the source.

Because the dataset contains just one station, coverage across Curicó is narrow and does not capture spatial differences that may exist elsewhere in the city or region. The lack of multiple rows also means there is no historical spread to compare against; the reported values represent a single point in time rather than a range of conditions. Consequently, while the data are up‑to‑date, they provide only a snapshot of particulate concentrations at one location and should be interpreted as such.
