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 La Unión, and it reports a single pollutant: PM2.5 measured in micrograms per cubic metre. The recorded concentration is 14.0 µg/m³, with the minimum, median and maximum all equal to that value because there is just one observation. This reading was last updated on 2026-02-10 13:00 UTC, which falls within the past three days, so the data can be considered recent.

Because the dataset contains a single row, coverage across pollutants is limited to PM2.5 alone, and there are no older or unknown‑timestamp entries for this location. The uniform value indicates that only one measurement point contributes to the city’s reported air quality, meaning spatial variation within La Unión cannot be assessed from these data. Users should keep in mind that conditions may differ across neighborhoods and times not captured by this solitary, freshly updated observation.
