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 Ferno contains three measured pollutants – nitrogen dioxide (NO2), ozone (O3) and particulate matter ≤ 10 µm (PM10). All values come from a single monitoring location identified as FERNO, so the city’s air‑quality picture is based on one station. The most recent readings are fairly fresh: NO2 and O3 were recorded at 2026-02-09 03:00 UTC, while PM10 was logged at 2026-02-08 19:00 UTC.
Each pollutant currently has only a single reported value, which also serves as its minimum, median and maximum. NO2 is measured at 12.3254957 µg/m³, O3 at 6.990834 µg/m³ and PM10 at 53.9 µg/m³. Because there is no variation across the data – the ten‑percentile, median and ninety‑percentile are identical to the single reading – the dataset does not provide a range or spread for any of the pollutants.
With three rows of data covering three substances, the coverage is limited to one site and recent timestamps, meaning that spatial differences within Ferno cannot be captured. Users should keep in mind that conditions may differ across neighborhoods or at other times of day, as the current snapshot reflects only the specific moments when the sensors last reported.
