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 dataset for Usurbil contains a single monitoring station that reports five common pollutants: nitrogen dioxide (NO2), ozone (O3), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulfur dioxide (SO2). All five measurements were last updated on 2026‑02‑09 at 15:00 UTC, so the data are fresh within the past week.
For each pollutant the recorded values are identical across the minimum, median, maximum and the 10th–90th percentiles, indicating no observed variation in this snapshot. NO2 is reported at 11.0 µg/m³, O3 at 73.0 µg/m³, PM10 at 8.0 µg/m³, PM2.5 at 2.0 µg/m³ and SO2 at 5.0 µg/m³. Because the dataset consists of only one row, there is no spread to describe; the single reading represents both the typical and extreme values for the period covered.
The coverage is therefore limited to a single location, which means city‑wide conditions may differ from what this station captures. While the timestamps are recent, the lack of multiple stations or historical rows prevents assessment of temporal trends or spatial variability within Usurbil. Users should keep in mind that these figures reflect only one point measurement taken on 2026‑02‑09 and that air quality can change across neighborhoods and over time.
