Air quality today

The air quality in Niort today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).

Measurements show a PM2.5 concentration of 0.5 µg/m³ and a PM10 level of 0.8 µg/m³, based on six valid observations recorded by OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Niort air‑quality dataset currently contains observations for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). Data come from 14 individual rows collected at four monitoring sites, all located in the Niort Venise area.

The most recent measurements are from 2026‑02‑10 15:00 UTC for NO2, PM10, O3 and PM2.5, meaning those four pollutants have been updated within the last three days. The latest NO reading is older, dated 2024‑03‑11 07:00 UTC, and is flagged as “old data”. Across all rows, five entries are from the past three days, one entry is older than a year, and eight rows are classified as “old” (more than three days but less than thirty). No records are marked unknown.

For NO2 the values range from 2.8 to 11.7 µg/m³ with a median of 8.75 µg/m³; PM10 spans 0.8 to 26.5 µg/m³ with a median of 18.4 µg/m³, showing a broader spread. Ozone values are higher overall, from 26.2 up to 54.7 µg/m³ and a median of 40.45 µg/m³. PM2.5 is the lowest‑concentration pollutant in this set, ranging between 0.5 and 17.1 µg/m³ with a median of 8.8 µg/m³. NO shows the widest range, from 1.6 to 75.2 µg/m³ and a median of 38.4 µg/m³, but its data are considerably older.

Because the dataset includes only four sites and some pollutants have outdated records, the snapshot may not capture short‑term or location‑specific variations across Niort. Users should keep in mind that conditions can differ by neighbourhood and time beyond what these limited, partly stale observations reflect.

Data notes

The dataset for Niort includes six valid measurements and is updated within three days, with the most recent values recorded on 2026‑02‑10 at 15:00 UTC. These figures represent a snapshot of ambient conditions captured by the monitoring network; air quality can differ across neighborhoods and change throughout the day, so local variations may not be reflected in this summary.
