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 Walsrode contains a single monitoring location – Allertal – which supplies the full set of five measured pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). Because there is only one row in the source table, station coverage is limited to this lone site.
The most recent observations are fairly current for four of the pollutants, with the last update recorded on 2026-02-10 02:00 UTC for NO₂, O₃, PM₁₀ and PM₂.₅. The NO measurement is older, dated 2024-03-11 11:00 UTC, which means that the nitrogen monoxide value reflects conditions from more than a year ago while the other four compounds show data refreshed within the past few days.
All five pollutants have identical single‑value statistics because each is represented by only one measurement. The recorded concentrations are 1.48807 µg/m³ for NO, 15.5319 µg/m³ for NO₂, 14.2868 µg/m³ for O₃, 35.0625 µg/m³ for PM₁₀ and 34.0737 µg/m³ for PM₂.5. Since the minimum, median and maximum are the same for each pollutant, there is no observable spread or variability in the data set.
Because the coverage relies on a single station and one of the pollutants (NO) has not been updated since early 2024, the snapshot does not capture spatial differences across Walsrode nor recent changes for that compound. Users should keep in mind that air‑quality conditions can differ by neighbourhood and time, and the available numbers represent only the point measurements from Allertal at the timestamps noted above.
