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 Nieuwer Ter Aa currently includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀) and particulate matter ≤2.5 µm (PM₂.₅). All data come from a single monitoring site, identified as Breukelen‑Snelweg, so the city’s coverage consists of five rows of observations from one location.
Each pollutant shows a single reported value because the most recent reading is also the only one available in the dataset. NO registers 2.41 µg/m³, NO₂ 29.99 µg/m³, O₃ 15.52 µg/m³, PM₁₀ 5.71 µg/m³ and PM₂.₅ 6.74392 µg/m³; for every parameter the minimum, median and maximum are identical, indicating no observed spread over time. The latest update for all five measurements was recorded on 2026‑02‑10 at 21:00 UTC, which falls within the “updated within 7 days” freshness category used by OpenAQ.
Because the dataset contains only one active station and a single timestamp per pollutant, the picture of air quality in Nieuwer Ter Aa is limited to this moment and location. The lack of multiple rows or older entries means that variations across different neighbourhoods or over longer periods are not captured here. Users should keep in mind that conditions can differ elsewhere in the city or at other times, and additional monitoring points would be needed for a more comprehensive view.
