Air quality today
The air quality in Saint‑Genis‑Laval is classified as Good today. The primary pollutant measured is PM2.5, with a reported concentration of 0.0 µg/m³ based on five valid observations from OpenAQ data.
No other pollutants reached reporting thresholds, and the limited dataset confirms the overall favorable condition. 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 Saint‑Genis‑Laval dataset contains five measured variables: PM1, PM2.5, relative humidity, temperature and the particle counter UM003. All of these come from a single monitoring location identified as Longchêne, so the city’s air‑quality picture is based on one station row. The most recent reading for every pollutant was recorded on 2026‑02‑10 at 18:00 UTC, meaning the data are fresh within the last three days.
For the particulate matter metrics both PM1 and PM2.5 report a value of 0.0 µg/m³, with no variation across minimum, median or maximum – the dataset shows a uniform zero reading for these pollutants at the time of capture. Relative humidity is reported as 37.17899983723959 % and temperature as 23.896999867757163 °C; each of these has identical min, median and max values, indicating that only one measurement point is available rather than a range over time. The UM003 particle concentration stands at 135.62533315022787 particles/cm³, also with a single recorded value.
Because the data stem from just one sensor, there is no spread or temporal depth to describe trends; all five variables share the same timestamp and location. Consequently, while the dataset provides current snapshots for each pollutant, it cannot capture spatial differences across Saint‑Genis‑Laval or changes throughout the day. Users should keep in mind that conditions may vary elsewhere in the city and at other times beyond this single observation.
