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 Hildesheim air‑quality dataset contains measurements for five pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). All data come from a single monitoring location, “Hildesheim Verkehr”, so the city’s overall picture is based on one row of observations for each pollutant.
The most recent values are very fresh for four of the five substances, with the latest timestamps recorded on 2026‑02‑10 at 18:00 UTC. CO registers 676.271 µg/m³, NO₂ 34.7704 µg/m³, PM₁₀ 16.2675 µg/m³ and PM₂.5 12.2534 µg/m³, each reported as the minimum, median and maximum for that day – indicating no observed variation within the sampled period. In contrast, the NO measurement is older, last updated on 2024‑03‑11 at 11:00 UTC, showing a value of 22.668701 µg/m³ with identical min, median and max.
Because only one station contributes data, the range for each pollutant collapses to a single point, so there is no spread to describe across different sites or times within Hildesheim. The dataset therefore reflects a snapshot rather than a comprehensive city‑wide assessment; conditions can differ in other neighborhoods or at later dates. Nonetheless, the presence of all five key pollutants and the recent timestamps for most of them provide a current baseline for the monitored location.
