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 Kleinwallstadt air‑quality record consists of a single monitoring location on Hofstetter Straße, so the dataset contains one row for each pollutant. Five pollutants are represented: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). Because there is only one station, the data set does not provide spatial coverage across the city; conditions can differ in other neighbourhoods or at other times.
The most recent measurements are from 2026‑02‑10 17:00 UTC for NO₂, O₃ and PM2.5, showing that three of the five pollutants have been updated within the last three days. The NO value dates back to 2024‑03‑11 11:00 UTC, while the SO₂ reading is from 2018‑05‑22 06:00 UTC, indicating that older data still appear in the record for two substances. Across all pollutants the recorded values are single points rather than ranges: NO sits at 2.68 µg/m³, NO₂ at 17.51 µg/m³, O₃ at 46.8 µg/m³, PM2.5 at 4.81 µg/m³ and SO₂ at 3.33 µg/m³. Because each pollutant has only one observation, median, minimum and maximum values are identical.
Overall the dataset shows a mixed freshness profile: three pollutants are current, while two rely on data that are several years old. The limited number of stations means the figures describe conditions at one specific site rather than city‑wide averages, so variations elsewhere in Kleinwallstadt may not be captured by these numbers.
