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 Niederzier currently consists of three pollutant measurements taken at a single monitoring site. All three values were last updated on 2026-02-10 at 17:00 UTC, which means the data are fresh – each reading is dated within the past three days.
Three pollutants are represented: ozone (O3) at 48.637 µg/m³, particulate matter with a diameter below 10 µm (PM10) at 1.919 µg/m³, and fine particulate matter below 2.5 µm (PM2.5) at 1.05 µg/m³. For each pollutant the minimum, median and maximum values are identical, indicating that only one observation per pollutant is available from this site. Consequently there is no spread in the data; the reported figures reflect a single snapshot rather than a range of measurements over time.
Because the dataset draws from just one station, spatial coverage across Niederzier is limited. While the timestamps are recent, the lack of multiple rows or stations means that variations in air quality across different neighbourhoods or at other times of day are not captured here. Users should keep in mind that conditions can differ elsewhere in the city and that additional measurements would be needed to describe broader patterns.
