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 dataset for Osijek contains five measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10) and sulphur dioxide (SO2). Altogether there are seven rows of data coming from two monitoring stations, identified as OSIJEK‑1 and OSIJEK‑2. The most recent update for every pollutant was recorded on 2026‑02‑09 at 03:00 UTC, so the freshest values are all less than a week old.
CO is reported only by station OSIJEK‑2 with a single value of 500.0 µg/m³; the minimum, median and maximum are identical, indicating that only one measurement is available. SO2 also comes from OSIJEK‑2 but shows a broader spread: values range from –2.1 to 2.0 µg/m³, with a median near zero (–0.05 µg/m³). In contrast, NO2, O3 and PM10 each have one reading from station OSIJEK‑1, all three sharing the same figure for minimum, median and maximum – 15.8 µg/m³ for NO2, 9.1 µg/m³ for O3 and 35.3 µg/m³ for PM10.
Because each pollutant is represented by only one or two rows, the coverage across the city is limited and uneven: CO and SO2 are measured at OSIJEK‑2 while the other three pollutants come from OSIJEK‑1. The dataset contains no older or unknown timestamps; all seven entries fall into the “updated within 7 days” freshness bucket. Consequently, while the data are recent, they provide a snapshot rather than a continuous picture of air quality across different parts of Osijek.

Data notes
The data shown for Osijek is based on four valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑09T03:00:00+00:00 (Updated within 3 days). These values represent a snapshot of ambient conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
