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 OpenAQ feed for Oldenburg in Lower Saxony currently provides measurements for eight pollutants: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), particulate matter 1 µm (PM1), particulate matter 2.5 µm (PM2.5), particulate matter 10 µm (PM10), relative humidity and temperature. These data come from two monitoring stations – the Hauptbahnhof site and the Heiligengeistwall site – recorded across ten individual rows.
Most of the values are very recent, with the newest timestamps dated 2026‑02‑10 at 19:00 UTC for PM2.5, PM1, relative humidity and temperature, and 2026‑02‑10 at 18:00 UTC for CO, NO2 and PM10. The only older entry is the nitrogen oxide measurement, last updated on 2024‑03‑11 at 11:00 UTC. This means that, apart from NO, all pollutants have been refreshed within the past few days.
The dataset shows a modest spread for particulate matter. At the Hauptbahnhof station PM2.5 ranged from about 19.5 µg/m³ to 37.2 µg/m³, with a median of 28.4 µg/m³; PM1 was recorded at 21.9 µg/m³ and PM10 at 28.3 µg/m³ at the Heiligengeistwall site. Carbon monoxide is represented by a single value of 705.857 µg/m³, while NO2 is reported as 41.5 µg/m³. Relative humidity was 64.05 % and temperature 9.23 °C at the Hauptbahnhof location.
Overall, the coverage is uneven: most pollutants have only one recent observation per station, and the nitrogen oxide reading is considerably older than the rest. Consequently, while the data give a snapshot of current air‑quality conditions in Oldenburg, variations across different parts of the city or over shorter time intervals may not be fully captured.
