Air quality today
The air quality in Saint‑Michel‑de‑Maurienne is classified as Good today. The primary pollutant identified is PM10, with two valid measurements recorded for the day.
According to OpenAQ data, the measured concentration of PM10 is 4.5 µg/m³ based on the available observations. 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 Saint‑Michel‑de‑Maurienne currently draws on three data rows collected at a single monitoring site, Maurice Trafic. All three standard pollutants tracked by OpenAQ are present: nitrogen monoxide (NO), nitrogen dioxide (NO₂) and particulate matter up to 10 µm (PM₁₀). Because each pollutant has only one row of measurements, the dataset is very small, but it does give a snapshot of recent conditions at that location.
The most recent NO reading dates back to 2024‑03‑11 09:00 UTC and shows a value of –1.5 µg/m³, which is the same figure for its minimum, median and maximum – indicating only one recorded point. The NO₂ data are much fresher, last updated on 2026‑02‑10 15:00 UTC, with a single measurement of 28.1 µg/m³ that also serves as the full range for this pollutant. PM₁₀ was most recently reported on 2026‑02‑09 03:00 UTC and records a value of 4.5 µg/m³, again identical across its statistical summary.
Because each pollutant is represented by just one observation, there is no spread or variability to describe; the dataset does not provide a range of values over time. The timestamps show that NO data are older than two years, while NO₂ and PM₁₀ have been refreshed within the past few days. This uneven freshness means that recent information is available for nitrogen dioxide and fine particles, but the nitric oxide figure may no longer reflect current conditions. Users should keep in mind that air quality can differ across neighborhoods and over time, and the limited number of rows here captures only a single moment at one monitoring point.
