Air quality today
The air quality in Voiron today is classified as Good. The main pollutant identified is PM10, and the latest available measurement shows a concentration of 6.0 µg/m³ based on three valid readings.
Data are shown via OpenAQ. 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 Voiron includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter 10 µm or less (PM₁₀). All data come from a single monitoring station, “Voiron Urbain”, so the dataset contains one row per pollutant. The timestamps show that the most recent NO₂ and O₃ values were recorded on 2026‑02‑10 at 15:00 UTC, while the latest PM₁₀ reading dates to 2026‑02‑09 at 03:00 UTC. The NO measurement is older, last updated on 2024‑03‑11 at 09:00 UTC, making it the least current entry in the set.
Across the four pollutants the reported concentrations are single values with no observed variation: NO sits at 7.7 µg/m³, NO₂ at 8.9 µg/m³, O₃ at 57.7 µg/m³ and PM₁₀ at 6.0 µg/m³. Because each pollutant has only one recorded minimum, median and maximum, the dataset does not provide a spread or range for any of them. This uniformity reflects the limited number of rows rather than stable atmospheric conditions.
Overall, the data are fairly fresh for NO₂, O₃ and PM₁₀ – all updated within the past few days – but the NO figure is over two years old. With only one monitoring location, the snapshot may not capture spatial differences across Voiron, and the lack of multiple observations limits insight into short‑term fluctuations. Users should keep in mind that conditions can change throughout the day and between neighbourhoods, even though the current dataset presents a single point‑in‑time picture for each pollutant.

Data notes
The current dataset for Voiron includes three valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 15:00 UTC (Updated within 3 days). These values represent a snapshot of ambient conditions captured by our monitoring network; however, air quality can differ across neighborhoods and change throughout the day, so local variations may not be reflected in this summary.
