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 Sebeș air‑quality record draws on seven data rows collected at two monitoring stations, covering five measured pollutants: nitrogen dioxide (NO₂), particulate matter 10 µm (PM₁₀), ozone (O₃), carbon monoxide (CO) and sulphur dioxide (SO₂). The most recent updates for four of the pollutants were logged on 2026‑02‑10 at 19:00 UTC, showing that fresh measurements are available for NO₂, PM₁₀, CO and SO₂. Ozone is the exception; its only entry dates back to 2022‑03‑14 at 08:00 UTC, indicating that ozone data are considerably older than the rest.
For the recent pollutants, the observed values span a modest range. NO₂ varies from a low of 32.55 µg/m³ to a high of 58.62 µg/m³, with a median around 45.59 µg/m³ and the central 80 % of readings falling between roughly 35.16 and 56.01 µg/m³. PM₁₀ shows a similar spread, ranging from 60.39 to 88.39 µg/m³; its median is 74.39 µg/m³ and the 10th‑90th percentile band runs from about 63.19 to 85.59 µg/m³. By contrast, the CO and SO₂ entries are anomalous, both reporting constant negative values (‑1000.0 µg/m³ for CO and ‑1.0 µg/m³ for SO₂) across their single recent row, which suggests sensor or data‑recording issues rather than realistic concentrations.
Overall, the dataset provides a fairly current snapshot for NO₂ and PM₁₀ but is limited in breadth: only two stations contribute, and ozone information is outdated. The presence of implausible CO and SO₂ figures further highlights gaps in coverage. Consequently, while recent trends for nitrogen dioxide and particulate matter can be described with the available numbers, a fuller picture of Sebeș’s air quality would require additional, up‑to‑date observations from more locations and reliable readings for all pollutants.

Data notes
The data shown for Sebeș is based on two valid measurements and was updated within three days, with the latest reading recorded at 2026‑02‑10 19:00 UTC. While this provides a recent snapshot of overall conditions, air quality can differ across neighborhoods and change throughout the day, so local variations may not be fully captured in these figures.
