Air quality today
The air quality in Pusignan today is classified as Good. The primary pollutant measured is PM2.5, with a reference value of 2.0 µg/m³, while the corresponding PM10 reference stands at 3.1 µg/m³. Four valid measurements were recorded to determine these values.
Data are shown via OpenAQ and reflect the current assessment for the city. 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 dataset for Pusignan includes measurements of five key 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 values come from a single monitoring site located in Saint‑Exupéry, giving a total of five rows of data, one for each pollutant.
The most recent observations were recorded on 2026-02-10 at 15:00 UTC for NO₂, O₃, PM10 and PM2.5, indicating that the majority of the dataset is up‑to‑date within the last three days. The NO measurement is older, with its latest entry dated 2024-03-11 at 09:00 UTC, which means that this particular pollutant has not been refreshed for almost two years. Because only one station supplies data, spatial coverage across Pusignan is limited; conditions can differ in other neighbourhoods or micro‑environments that are not captured here.
Across the five pollutants the recorded values show no variation within each series: NO is consistently 6.2 µg/m³, NO₂ stays at 4.4 µg/m³, O₃ remains at 65.8 µg/m³, PM10 holds steady at 3.1 µg/m³ and PM2.5 at 2.0 µg/m³. The median, minimum and maximum are identical for every pollutant, reflecting a single data point per compound rather than a range of observations. Consequently, while the dataset provides a snapshot of current air quality at the Saint‑Exupéry location, it does not convey variability over time or across different parts of the city. Users should keep in mind that actual conditions elsewhere in Pusignan may differ from these values.
