Air quality today
The air quality in Saint‑Junien is classified as Good today. The primary pollutant measured is PM10, and the latest data show a PM10 concentration of 11.6 µg/m³ based on four valid observations recorded by OpenAQ.
Overall conditions meet the criteria for the Good category with no additional pollutants reported. 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‑Junien air‑quality record includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM₁₀) and sulfur dioxide (SO₂). Data come from two monitoring sites that together contributed ten individual rows of observations. The most recent values are fairly fresh for some gases: NO₂ and O₃ were last updated on 2026‑02‑10 at 15:00 UTC, while PM₁₀ and SO₂ have timestamps from the previous day (2026‑02‑09 03:00 UTC for PM₁₀ and 2026‑02‑09 19:00 UTC for SO₂). The NO record is older, with its latest entry dated 2024‑03‑11 09:00 UTC.
Across the five pollutants the observed concentrations span modest ranges. NO varied between 0.9 and 3.8 µg/m³, with a median of about 2.35 µg/m³; NO₂ ranged from 4.8 to 11.9 µg/m³, centering near 8.35 µg/m³; O₃ showed the widest spread, from 7.2 up to 40.6 µg/m³ and a median of roughly 23.9 µg/m³. PM₁₀ values were tightly clustered between 8.8 and 11.6 µg/m³ (median 10.2 µg/m³), while SO₂ remained low, ranging only from 0.2 to 0.3 µg/m³ with a median of 0.25 µg/m³.
The dataset is uneven in terms of recency: the nitrogen monoxide reading is more than two years old, whereas the other four pollutants have updates within the last few days. This mix of fresh and dated entries means that while recent snapshots are available for most contaminants, the NO information may not reflect current conditions. Because only two stations contribute data, spatial variation across Saint‑Junien cannot be captured in detail; measurements represent the specific locations of those monitors at the times recorded.

Data notes
The data shown for Saint‑Junien is based on four valid measurements and was updated within 3 days, with the latest reading recorded at 2026‑02‑10 15:00 UTC. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and change throughout the day, so values may not represent the entire city at any given moment.
