What the data includes

The current station data listed for this city is focused on particulate matter (PM). In Cauquenes there are two recorded rows, one for PM10 and one for PM2.5, each coming from the same monitoring site, Cauquenes Sivica. Both measurements were last updated within the past three days: PM10 at 15.0 µg/m³ on 2026-02-10 12:00 UTC and PM2.5 at 11.0 µg/m³ on 2026-02-10 11:00 UTC. Because only a single sensor contributes data for each pollutant, the dataset does not provide spatial diversity across the city.

The values are identical across their minimum, median and maximum statistics, indicating no observed variation in the limited sample period (PM10 consistently 15.0 µg/m³, PM2.5 consistently 11.0 µg/m³). With just two rows and no older or unknown timestamps, the coverage is very recent but also very narrow; conditions elsewhere in Cauquenes may differ from those captured at this single location. Consequently, while the data are fresh, they offer a snapshot rather than a comprehensive view of air quality throughout the municipality.
