Air quality today
The air quality in Saint‑Dizier today is classified as Good. The primary pollutant measured is PM2.5 (fine particles).
Four valid measurements were recorded, showing a PM2.5 reference value of 1.7 and a PM10 reference value of 7.6. 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‑Dizier air‑quality record draws from a single monitoring site (St DIZIER L. Michel) that supplies six pollutant measurements: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). The dataset contains six rows in total, one for each pollutant.
The most recent data are fairly fresh for five of the six compounds, with updates recorded on 2026‑02‑10 at 15:00 UTC for NO₂, O₃, PM₁₀ and PM₂.₅, and on 2024‑03‑11 at 08:00 UTC for NO. The SO₂ reading is much older, last refreshed on 2019‑09‑20 at 08:00 UTC, indicating an uneven temporal coverage across the pollutant set.
All values are single observations rather than ranges, so each pollutant shows a constant figure in this snapshot: NO stands at 7.7 µg/m³, NO₂ at 5.0 µg/m³, O₃ at 73.0 µg/m³, PM₁₀ at 7.6 µg/m³, PM₂.₅ at 1.7 µg/m³ and SO₂ at 5.1 µg/m³. Because each metric has only one recorded value (minimum, median and maximum are identical), there is no observable spread within the data for any pollutant.
Overall, the dataset provides a complete set of six common air‑quality indicators but relies on a single location and contains one markedly outdated measurement (SO₂). Consequently, while the recent timestamps give a current picture for most pollutants, the limited spatial coverage and the old SO₂ entry mean that conditions can differ across Saint‑Dizier and over time.
