What the data includes

The air‑quality dataset for Guty Duże contains measurements from a single monitoring station, giving one row of data for each of the five pollutants tracked: nitrogen dioxide (NO2), ozone (O3), sulphur dioxide (SO2), particulate matter up to 10 µm (PM10) and particulate matter up to 2.5 µm (PM2.5). The most recent observations were recorded on 2026‑02‑10 at 19:00 UTC for NO2, O3, SO2 and PM10, while the PM2.5 reading dates back to 2025‑10‑10 at 14:00 UTC, so five of the six values are fresh within the last week and one is older than three months.

Across the pollutants the recorded concentrations span a modest range. NO2 varies between 14.2 and 15.7 µg/m³ with a median of about 15 µg/m³; O3 shows a broader spread from 21.2 up to 55.0 µg/m³, median 38 µg/m³; SO2 is low‑level, ranging 3.2–5.0 µg/m³ with a median near 4 µg/m³. PM10 has only a single reported value of 40.1 µg/m³, and PM2.5 likewise records a solitary figure of 3.1 µg/m³. Because the dataset consists of just one station, the spatial coverage is limited to that location, meaning conditions elsewhere in Guty Duże may differ.

Overall the data set is recent for most pollutants, but the older PM2.5 entry highlights an uneven temporal coverage. With only one monitoring point, any snapshot reflects local conditions at that site rather than a city‑wide picture, and users should keep in mind that air quality can change across neighborhoods and over time.
