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 air‑quality record for Offenbach am Main currently draws on a single monitoring site, Untere Grenzstraße, which supplies five rows of data – one for each measured pollutant: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), particulate matter up to 10 µm (PM₁₀) and particulate matter up to 2.5 µm (PM₂.₅). Because there is only one station, the dataset does not capture spatial variation across the city; conditions reported here reflect the environment at that specific location.
The timestamps show a mixed picture of data freshness. The most recent updates are from 2026‑02‑10 17:00 UTC for NO₂, PM₁₀ and PM₂.₅, indicating those three pollutants have been refreshed within the last three days. In contrast, CO data are dated 2023‑02‑02 00:00 UTC and NO data from 2024‑03‑11 11:00 UTC, both classified as older records. Consequently, while half of the parameters provide near‑real‑time information, the other half rely on measurements that are several years old.
All five pollutants show a single recorded value with no observed spread – each has identical minimum, median and maximum figures. CO registers 148.99954 µg/m³, NO 5.72631264 µg/m³, NO₂ 37.88819 µg/m³, PM₁₀ 6.255 µg/m³ and PM₂.₅ 4.197649 µg/m³. The lack of variability suggests that the dataset captures only one snapshot per pollutant rather than a range of recent readings. Users should keep in mind that city‑wide air quality can differ by neighbourhood and time, and the current data set provides limited temporal depth for CO and NO while offering more up‑to‑date information for the other three pollutants.
