Air quality today
The air quality in Rognac today is classified as Moderate. The primary pollutant measured is PM2.5, with a reported concentration of 15.2 µg/m³. Data are shown via OpenAQ and reflect one valid measurement for the day.
Overall conditions indicate a moderate level of fine particulate matter without additional pollutants reported. 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 Rognac air‑quality record draws from five monitoring rows, but only two of them contain recent data. For fine particulate matter (PM2.5) the most up‑to‑date observation was recorded on 2026‑02‑09 03:00 UTC at the “Rognac les Brets” site, showing a maximum value of 15.2 µg/m³, a median of about 12.1 µg/m³ and a minimum of 9.1 µg/m³; the spread between the 10th percentile (≈9.7 µg/m³) and the 90th percentile (≈14.6 µg/m³) indicates modest variability across the limited recent samples. Ozone (O3) is represented by a single older entry from 2023‑04‑17 11:00 UTC at station FR02020, reporting a constant value of 70.2 µg/m³ – there is no range because only one measurement exists. Coarse particulate matter (PM10) and sulfur dioxide (SO2) each have just one historic record from 2020‑01‑15 13:00 UTC and 2020‑05‑15 07:00 UTC respectively, both also at FR02020, with values of 18.6 µg/m³ for PM10 and 0.0 µg/m³ for SO2.
Overall the dataset is uneven: half of the rows are classified as “old” (four out of five) while only one row provides data that was refreshed within the past week. This means that, apart from the recent PM2.5 series, most pollutant readings reflect conditions that may no longer be representative of current air quality in Rognac. The limited number of stations—especially for O3, PM10 and SO2 where only a single site contributes data—restricts spatial coverage, so variations across different neighbourhoods are not captured. Consequently, while the available numbers give a snapshot of recent fine‑particle levels, they offer little insight into the broader or current state of other pollutants in the city.

Data notes
The data for Rognac reflects a single valid measurement and is updated within 3 days, with the latest reading recorded on 2026‑02‑09 at 03:00 UTC. This snapshot provides a brief view of current air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in this single point of data.
