Air quality today
The air quality in Saint‑Pierre today is classified as Good. The primary pollutant identified is PM10, and the measured concentration aligns with a reference value of 12.0 µg/m³ based on three valid observations.
Data are shown via OpenAQ and reflect the current assessment for this location. 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 Saint‑Pierre contains measurements for four pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter 10 µm or less (PM10) – all recorded at a single monitoring site, Ligne Paradis. In total there are four rows of data, one for each pollutant, so the coverage is limited to this lone location.
The most recent values are fairly fresh: NO₂ and O₃ were last updated on 2026‑02‑10 at 03:00 UTC, while PM10 was refreshed on 2026‑02‑09 at 03:00 UTC. The NO measurement is older, with its latest timestamp from 2024‑03‑11 at 07:00 UTC and flagged as “Old data”. Because each pollutant has only one observation, the reported minimum, median and maximum are identical – 12.1 µg/m³ for NO, 8.7 µg/m³ for NO₂, 13.1 µg/m³ for O₃ and 12.0 µg/m³ for PM10 – indicating no observed variability within the dataset.
These numbers illustrate a narrow snapshot rather than a range of conditions across Saint‑Pierre. The data are recent for three of the four pollutants but rely on a single station, so they cannot capture spatial differences that may exist elsewhere in the city or changes over longer periods. Users should keep in mind that while the timestamps suggest up‑to‑date information for most compounds, the overall picture is constrained by limited geographic coverage and the older NO reading.
