Air quality today
The air quality in Marignac today is classified as Good. The primary pollutant measured is PM2.5, with a recorded concentration of 0.68 µg/m³ based on five valid observations reported through OpenAQ.
No other pollutants reached measurable levels for this assessment. 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 Marignac contains measurements from a single monitoring location, recorded on 2026‑02‑10 at 18:00 UTC. Five pollutants are reported: PM1 at 0.0138333335518837 µg/m³, PM2.5 at 0.6833333345750967 µg/m³, relative humidity at 69.81783345540363 %, temperature at 15.363333384195963 °C, and UM003 particles at 134.56950000127156 particles/cm³. All values are identical for minimum, median and maximum, indicating that only one observation is available for each parameter.
Because the data set consists of just one row, coverage across the city is very limited; there are no additional stations to capture spatial variation within Marignac or its surrounding area. The timestamps are recent, falling within the “updated within 3 days” freshness bucket, so the information reflects conditions from a single point in time rather than an ongoing series.
The uniformity of the recorded values means there is no observable spread for any pollutant, and each metric currently has only one data point to describe typical conditions. Consequently, while the dataset provides a snapshot of air quality, temperature, humidity and particle counts at the Usseau site, it cannot represent broader temporal trends or differences across neighborhoods in Marignac.
