Latest sensor values
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 current station data listed for this city is focused on particulate matter (PM). Only one monitoring row is available for La Serena, and it reports a single pollutant: PM2.5 measured in micrograms per cubic metre. The recorded value is consistently 17.0 µg/m³, with the minimum, median and maximum all equal to that figure, indicating no variation within this dataset. The most recent measurement was taken on 2026-02-10 13:00 UTC, which falls within a three‑day freshness window, so the data can be considered up‑to‑date for the short term.
Because there is just a single station entry, coverage across the city and across different pollutants is very limited. The dataset does not include any older or unknown timestamps, but the lack of additional rows means spatial variability cannot be assessed from this source alone. Consequently, while the available PM2.5 reading reflects conditions at one location on a recent date, broader air‑quality patterns in La Serena may differ elsewhere or at other times.
