Air quality today
The air quality in Lognes is assessed as Good today. The primary pollutant identified is PM10, with a reference concentration of 5.2 µg/m³ based on three valid measurements reported via OpenAQ.
These figures indicate that the current particulate levels are within the range associated with the Good 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 dataset for Lognes contains a single monitoring row that reports four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3) and particulate matter ≤ 10 µm (PM10). All measurements are expressed in micrograms per cubic metre.
For NO the only recorded value is 18.4 µg/m³, measured at the LOGNES site on 2024‑03‑11 07:00 UTC; the same single reading serves as the minimum, median and maximum, indicating no observed variation within the data set. NO2 is reported once at 13.3 µg/m³ from the LOGNES location on 2026‑02‑10 15:00 UTC, again with identical min‑med‑max values. Ozone appears a single time as 65.0 µg/m³, also recorded at LOGNES on 2026‑02‑10 15:00 UTC, and PM10 is listed once at 5.2 µg/m³ from LOGNES on 2026‑02‑09 03:00 UTC.
Because there is only one row per pollutant, the coverage across the city is very limited; no spatial distribution or multiple time points are available to show changes over days or weeks. The freshest timestamps are from early February 2026 for three of the four pollutants (NO2 and O3 on 2026‑02‑10, PM10 on 2026‑02‑09), while the NO measurement is older, dating back to March 2024. This mix of recent and relatively old data means that the snapshot reflects conditions at specific moments rather than a continuous record.
Overall, the dataset provides exact single-point values for each pollutant but lacks breadth in both time and location, so variations across Lognes cannot be assessed from these figures alone.
