Air quality today
The air quality in Passy is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 10.3 µg/m³ and a PM10 level of 14.0 µg/m³, based on four valid observations collected via OpenAQ.
These values reflect the present monitoring snapshot for Passy in the Auvergne‑Rhône‑Alpes region. 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 Passy air‑quality record consists of a single monitoring station that reports five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10) and particulate matter 2.5 µm or less (PM2.5). Because there is only one row of data, the coverage is limited to this lone site.
The most recent measurement for NO dates back to 2024‑03‑11 09:00 UTC, while the latest values for NO2 and O3 were recorded on 2026‑02‑10 15:00 UTC. PM10 and PM2.5 are slightly older, with their newest entries from 2026‑02‑09 03:00 UTC. All five pollutants have a single reported value, so the minimum, median and maximum are identical for each: NO 55.9 µg/m³, NO2 8.9 µg/m³, O3 59.5 µg/m³, PM10 14.0 µg/m³ and PM2.5 10.3 µg/m³.
Because the dataset contains only one observation per pollutant, there is no spread to describe; each metric reflects a single point in time rather than a range of conditions. The timestamps show that the NO data are over two years older than the other gases, indicating uneven freshness across pollutants. Overall, the station provides recent information for most compounds (within the last few days), but the lack of multiple rows means temporal variability and spatial differences within Passy cannot be captured from this source alone.
