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 dataset for Vilcún includes five measurement rows covering a single monitoring site, Cherquenco. All five pollutants are represented: PM1 at 0.3178333334624768 µg/m³, PM2.5 at 0.7485000014305115 µg/m³, relative humidity at 55.61016667683919 %, temperature at 16.951500320434572 °C, and particle count (UM003) at 236.5541666666666 particles/cm³. Each value was recorded most recently on 2026‑02‑10 16:00 UTC, which the source flags as “Updated within 3 days,” indicating that the data are fresh for this reporting period.
Because only one station contributes to the record, the range for every pollutant is identical—the minimum, median and maximum values are all the same. This means there is no observed variability across the five rows; the dataset reflects a single snapshot rather than a distribution of conditions throughout the city. Consequently, while the data give an exact point‑in‑time picture at Cherquenco, they do not capture spatial differences that might exist elsewhere in Vilcún.
The completeness of pollutant coverage is high—each of the five measured species appears in every row—but the overall breadth of monitoring is limited to one location and a single recent timestamp. Users should keep in mind that air‑quality conditions can change across neighborhoods and over time, so this snapshot may not represent the full range of environmental states experienced across Vilcún.
