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 Saarlouis in the state of Saarland contains three measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂) and particulate matter up to 10 µm (PM₁₀). All values come from a single monitoring site, identified as Saarlouis‑Fraulautern, so the coverage consists of one station providing three separate rows of data.
The most recent observations are fairly current for two pollutants: NO₂ and PM₁₀ were last updated on 2026-02-10 18:00 UTC, which falls within a three‑day freshness window. In contrast, the NO measurement is older, with its latest timestamp recorded on 2024-03-11 11:00 UTC, classifying it as “old data.” Because only one station supplies the readings, there is no spatial variation captured across different parts of the city; conditions can therefore differ by location and time despite the numbers shown.
Across the three pollutants the reported values are identical for their minimum, median and maximum, indicating that each measurement set consists of a single data point rather than a range. NO registers at 2.82 µg/m³, NO₂ at 15.3 µg/m³ and PM₁₀ at 5.85 µg/m³. The lack of multiple observations means there is no spread to describe variability, and the dataset contains no rows classified as “unknown” or “future.” Overall, while the recent timestamps for NO₂ and PM₁₀ suggest up‑to‑date information, the solitary and dated NO entry highlights a limitation in temporal coverage for that pollutant.
