Air quality today
The air quality in Paray‑le‑Frésil is classified as Good today. The main pollutant measured is PM2.5, with a reported concentration of 0.8 µg/m³. In addition, the PM10 level is recorded at 1.8 µg/m³ based on four valid measurements from OpenAQ.
These values indicate that current concentrations are within the limits set for this category. 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 air‑quality record for Paray‑le‑Frésil consists of a single monitoring station that reports five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). The dataset contains one row per pollutant, so the overall coverage is limited to this lone site.
The most recent measurements are fairly up‑to‑date for four of the pollutants, with the last update recorded on 2026‑02‑10 15:00 UTC. Only NO is older, having its latest value from 2024‑03‑11 09:00 UTC, which means that the nitrogen monoxide reading is more than a year behind the others. Across all five substances the observed values are identical to their median and extreme percentiles, indicating no variation in this snapshot: NO sits at 0.4 µg/m³, NO₂ at 1.8 µg/m³, O₃ at 62.3 µg/m³, PM₁₀ at 1.8 µg/m³ and PM₂.5 at 0.8 µg/m³.
Because the data come from a single location, they represent conditions only at that point in Paray‑le‑Frésil; spatial differences within the city are not captured. The uniformity of the recorded values (minimum equals maximum for each pollutant) shows that the current dataset provides a static picture rather than a range of observations over time. While most pollutants have very recent timestamps, the older NO entry highlights an uneven freshness across the measured suite, suggesting that any interpretation should consider the limited temporal depth and the single‑station nature of the record.

Data notes
The dataset for Paray‑le‑Frésil includes four valid measurements and was refreshed recently, with the latest update recorded on 10 February 2026 at 15:00 UTC; it is therefore considered “Updated within 3 days.” These values represent a snapshot of ambient conditions at specific monitoring points. Air quality can differ across neighborhoods and change throughout the day, so this information reflects only the measured moments and locations.
