What the data includes
The Charleroi air‑quality record draws from a very small data set – two rows of observations that both come from the same monitoring site in the city. Only two pollutants are reported: ozone (O3) and fine particulate matter (PM2.5). For ozone, the single reading is 0.051 ppm, recorded at the Charleroi station on 2026‑02‑10 23:00 UTC. The PM2.5 measurement is 9.6 µg/m³, also taken at the same location and timestamp.
Both pollutants share identical freshness characteristics: each value was last updated on 2026‑02‑10 23:00 UTC, which falls within a seven‑day window from today, so the data can be described as recent. Because there is only one station contributing, the coverage across the city is limited; no additional sites are providing complementary or spatially varied readings. The statistical spread for each pollutant is effectively zero – the minimum, median, and maximum values are all the same (0.051 ppm for O3 and 9.6 µg/m³ for PM2.5), indicating that only a single measurement point exists rather than a range of observations.
In practical terms, this means the available information gives a snapshot of conditions at one specific spot in Charleroi at a particular moment, but it does not capture how air quality might differ across neighborhoods or change throughout the day. Users should keep in mind that while the timestamp is current, the limited number of rows and the single‑station source restrict the ability to infer broader city‑wide patterns from these figures alone.
