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 Jena in Thuringia contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). All values come from a single monitoring location, identified as Jena Dammstr., so the coverage consists of one station providing five separate rows of data.
The most recent observations are fairly current for four of the pollutants: NO₂, O₃, PM₁₀ and PM₂.₅ were each recorded on 2026‑02‑10 at 18:00 UTC, which falls within a three‑day freshness window. In contrast, the NO measurement is older, last updated on 2024‑03‑11 at 11:00 UTC, and is flagged as “Old data”. This uneven timestamp distribution means that while most of the dataset reflects near‑real‑time conditions, the nitrogen monoxide value may not represent present‑day levels.
All five pollutants show a single reported figure with no variation across the recorded period. The median (and also minimum and maximum) values are 1.24740005 µg/m³ for NO, 27.4988823 µg/m³ for NO₂, 35.484417 µg/m³ for O₃, 16.8162613 µg/m³ for PM₁₀ and 10.2191839 µg/m³ for PM₂.₅. Because each pollutant has only one data point, there is no spread to describe; the dataset therefore provides a snapshot rather than a range of conditions. Users should keep in mind that air quality can differ across neighborhoods and over time, and the limited spatial coverage (one station) and the older NO reading mean the picture presented here may not capture all local variations.

Data notes
The data shown for Jena are based on four valid measurements and were refreshed recently, having been updated within three days (last update: 2026‑02‑10T18:00:00+00:00). This snapshot reflects conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
