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 air‑quality dataset for Montoir‑de‑Bretagne contains five measured pollutants – nitrogen dioxide (NO₂), sulfur dioxide (SO₂), nitric oxide (NO), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). Data come from seven rows in total, but only two stations currently report the most recent values for NO₂ and SO₂; the other three pollutants are each represented by a single row.
The freshest observations were recorded on 2026‑02‑10 at 05:00 UTC for NO₂ (4.1 µg/m³), PM₁₀ (11.0 µg/m³) and PM₂.5 (5.8 µg/m³). SO₂ was last updated a few hours earlier on 2026‑02‑09 at 23:00 UTC with a value of 2.8 µg/m³. The NO measurement is considerably older, dated 2024‑03‑11 at 08:00 UTC and remains unchanged at 5.1 µg/m³.
Across the recent data the range for each pollutant is narrow: NO₂ varies from a minimum of 1.3 to a maximum of 4.1 µg/m³, with a median around 2.7 µg/m³; SO₂ spans –2.0 to 2.8 µg/m³, median roughly 0.4 µg/m³; PM₁₀ and PM₂.5 each have a single reported value (11.0 and 5.8 µg/m³ respectively). This limited spread suggests that the current snapshot captures only a small slice of the city’s air quality, and the dataset is uneven – more recent rows exist for particulate matter and nitrogen oxides than for sulfur compounds or nitric oxide.
Because many rows are either old (NO) or come from just two stations, the picture presented here does not cover the full spatial or temporal variability that can occur across Montoir‑de‑Bretagne. Users should keep in mind that conditions may differ in other neighbourhoods or at times outside the narrow window of the latest updates.

Data notes
The data shown for Montoir‑de‑Bretagne is based on four valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10 05:00 UTC.
