What the data includes

The current station data listed for this city is focused on particulate matter (PM). Only one pollutant is reported from the OpenAQ feed – PM2.5 – and there is a single monitoring row representing Coquimbo. The most recent measurement was recorded at 2026-02-10 13:00 UTC, which falls within the last three days, so the dataset is quite fresh. All three statistical points for this pollutant (minimum, median and maximum) are identical at 16.0 µg/m³, indicating that the single reading does not show any variation over time.

Because the coverage consists of just one station and a solitary PM2.5 value, there is no spread or range to compare across locations or dates within this city. The lack of additional rows or other pollutants means the picture is limited to this snapshot; conditions elsewhere in Coquimbo could differ from what this single point reflects. Nonetheless, the data available is up‑to‑date and provides a clear, if narrow, view of particulate matter levels at the time of measurement.
