Air quality today
The air quality in Saint‑Martin‑du‑Tertre is classified as Good today. The primary pollutant measured is PM2.5, with a reference value of 2.4 µg/m³, while the corresponding PM10 reference value stands at 4.9 µg/m³. Three valid measurements support this assessment and are displayed via OpenAQ.
Overall conditions meet the Good category criteria based on the available data. 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 Saint‑Martin‑du‑Tertre air‑quality profile includes three measured pollutants – ozone (O₃), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). Data come from a single monitoring station that reports one row for each pollutant, so the dataset contains three rows in total. All three rows were last updated on 2026‑02‑10 at 15:00 UTC, which places every measurement within the most recent three‑day window and means the information is current as of that date.
Ozone shows a single recorded value of 69.6 µg/m³, with the minimum, median and maximum all identical at 69.6 µg/m³, indicating no observed variation in this short snapshot. PM10 registers a constant 4.9 µg/m³ across its sole entry, while PM2.5 is recorded at 2.4 µg/m³ with the same uniform statistics. Because each pollutant has only one data point, there is no spread to describe; the reported figures represent both the typical and extreme values for the period covered.
The dataset’s coverage is therefore limited to one rural‑zone sensor (Zone Rurale Nord) that supplies simultaneous readings for all three pollutants. While the timestamps are fresh, the lack of multiple stations or repeated measurements means the picture is narrow in space and time. Conditions can differ across Saint‑Martin‑du‑Tertre, so these values give a snapshot rather than a comprehensive view of air quality throughout the whole commune.
