What the data includes

The current station data listed for this city is focused on particulate matter (PM). Available measurements include PM2.5 and PM10, coming from a total of eleven recent observations across four monitoring sites. The most recent timestamps for both pollutants are from 2026-02-10 18:00 UTC, meaning the newest data are less than a week old. Eight of the rows were recorded within the last seven days, while two are classified as older and one has an unknown timestamp, indicating that some historic values remain in the feed.

For PM2.5 the observed values range from about 6.65 µg/m³ up to 11.90 µg/m³, with a median near 9.04 µg/m³; six rows contribute to this series. PM10 shows a narrower spread, ranging from roughly 10.80 µg/m³ to 13.18 µg/m³ and a median of about 11.49 µg/m³ across five rows. The dataset therefore provides recent but limited spatial coverage, with more frequent updates for the finer particulate fraction than for PM10, and a small number of older or unknown‑dated entries that remind users conditions can differ by location and time.
