Air quality today
The air quality in Valence today is classified as Good. The primary pollutant measured is PM2.5, with a reported concentration of 6.9 µg/m³. In addition, PM10 levels are recorded at 9.1 µg/m³ based on four valid measurements.
These values reflect the current monitoring snapshot provided through 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 Valence air‑quality dataset contains observations for 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). All measurements come from a single monitoring location identified as Valence Urb. Centre, so the dataset represents one station row for each pollutant.
The most recent values are fairly current for four of the pollutants, with the last update recorded on 2026‑02‑10 at 15:00 UTC for NO2, O3, PM10 and PM2.5. The NO measurement is older, dated 2024‑03‑11 at 09:00 UTC, which means that the nitrogen monoxide data is nearly two years out of date compared with the other compounds.
Across the five pollutants the recorded concentrations are identical to their median values because each series contains only a single reading. NO registers 17.7 µg/m³, NO2 22.1 µg/m³, O3 35.5 µg/m³, PM10 9.1 µg/m³ and PM2.5 6.9 µg/m³. Because there is no spread of observations, the minimum, median and maximum are all the same for each pollutant, indicating that the dataset does not capture variability over time or across different sites within Valence.
In summary, the data set offers a snapshot from one urban centre with up‑to‑date information for four pollutants and an older entry for NO. The lack of multiple stations or repeated measurements means the figures describe only a single moment rather than broader spatial or temporal patterns in the city’s air quality.

Data notes
The data shown for Valence are based on four valid measurements and have been refreshed recently, with the latest update recorded at 2026‑02‑10T15:00:00+00:00 (updated within 3 days). This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
