The air quality in Haguenau today falls into the Moderate category according to OpenAQ data. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 15.3 µg/m³ based on three valid observations.
No additional pollutants reached reporting thresholds, and the available measurements reflect current conditions without further interpretation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
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 Haguenau draws from four measurement rows, each reporting a single pollutant at the same monitoring site – Place marché aux bestiaux. All four common urban pollutants are represented: nitrogen monoxide (NO) at 7.5 µg/m³, nitrogen dioxide (NO₂) at 18.2 µg/m³, ozone (O₃) at 45.6 µg/m³ and fine particulate matter (PM₂.5) at 15.3 µg/m³. Because each row contains only one value, the minimum, median and maximum are identical for every pollutant, giving a perfectly uniform snapshot rather than a distribution.
The timestamps show that the data set is fairly recent overall but not uniformly so. The most up‑to‑date readings are the NO₂ and O₃ values, both refreshed on 2026‑02‑10 at 15:00 UTC, while the PM₂.5 measurement was last updated a day earlier on 2026‑02‑09 at 03:00 UTC. The oldest entry is the NO reading from 2024‑03‑11 at 08:00 UTC, which is nearly two years older than the others and flagged as “Old data”. Consequently, three of the four pollutants have been refreshed within the last three days, whereas one remains dated.
With only a single monitoring location, the coverage across Haguenau is limited; spatial variations in pollutant concentrations cannot be captured. The dataset contains no rows classified as unknown or missing, but the presence of an older NO record highlights that not all parameters are updated with the same frequency. Users should keep in mind that conditions can differ elsewhere in the city and at other times, so this snapshot provides a concise but narrow view of current air quality in Haguenau.
