What the data includes

The OpenAQ feed for Timișoara contains data from eight monitoring sites spread across the city, amounting to a total of forty‑four individual measurement rows. The dataset covers ten pollutants and related variables: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of 1 µm (PM₁), 2.5 µm (PM₂.₅) and 10 µm (PM₁₀) size fractions, sulfur dioxide (SO₂), relative humidity, temperature and the additional parameter UM003. The most recent observations were recorded on 2026‑02‑10 at 19:00 UTC for CO, NO₂, SO₂, PM₁₀ and O₃, while the particulate measurements from the Parang street site (PM₁, PM₂.₅ and humidity) date back to 2026‑02‑08 at 10:00 UTC. Overall, the freshest timestamps are within the last week, indicating that most of the data is up‑to‑date, though a small portion of rows remains older than seven days.

Across the pollutants, the number of recorded samples varies considerably. CO, NO₂ and SO₂ each have nine recent entries, while O₃ appears in only three rows and PM₁, PM₂.5 and humidity are represented by a single measurement each. The concentration ranges also differ: CO spans from –1000 µg/m³ up to 2 148 µg/m³ with a median of about 40 µg/m³; NO₂ varies between roughly 14 and 87 µg/m³, median 28 µg/m³; SO₂ ranges from –1 to 16 µg/m³, median near 9 µg/m³; PM₁₀ lies between 11 and 69 µg/m³ with a median of 20 µg/m³; O₃ is recorded between 32 and 78 µg/m³, median 50 µg/m³. The single‑site particulate values are 21.9 µg/m³ for PM₁ and 29.4 µg/m³ for PM₂.5, with humidity at 56 %.

Because the dataset includes only a handful of recent rows for several key pollutants, especially O₃ and the fine particulates, the picture of air quality in Timișoara is limited to specific locations and times. Conditions can therefore differ across neighborhoods and may change between measurement moments, so users should consider the spatial and temporal gaps when interpreting the numbers.
