Air quality today
The air quality in Tremblay‑en‑France is currently classified as Good. The main pollutant identified is PM10, with a measured reference value of 8.6 µg/m³ based on three valid observations from OpenAQ data.
Overall conditions meet the Good category criteria according to the latest available measurements. 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
Tremblay‑en‑France’s OpenAQ feed contains four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter 10 µm or less (PM10) – each reported from a single monitoring row, so the city is represented by one station per pollutant. The most recent data point for NO dates back to 2024‑03‑11 09:00 UTC, while the other three pollutants have updates within the last few days of February 2026 (NO₂ and O₃ at 2026‑02‑10 15:00 UTC, PM10 at 2026‑02‑09 03:00 UTC). This means that for three of the four compounds the freshest measurements are less than three days old, but NO is based on a record from more than two years ago and is flagged as “old data”.
All four pollutants show a single recorded value with no observed variation across the dataset. The NO reading sits at 44.3 µg/m³, the NO₂ level is 13.8 µg/m³, ozone registers 65.7 µg/m³ and PM10 measures 8.6 µg/m³; each metric’s minimum, median and maximum are identical, indicating that only one measurement exists for each pollutant at this site. Because the dataset contains just one row per compound, there is no spread or percentile range to describe – the reported value is both the typical and extreme observation.
Overall, the coverage in Tremblay‑en‑France is limited: four rows across four pollutants, with three of them refreshed within a week but one lagging far behind. Consequently, while recent snapshots are available for NO₂, O₃ and PM10, the city’s air‑quality picture remains incomplete, especially for nitrogen monoxide, and conditions can differ across neighborhoods and times that are not captured by this sparse dataset.
