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 Székesfehérvár contains six pollutant measurements – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM2.5) and sulphur dioxide (SO₂). Each pollutant is represented by a single monitoring row, so the total station coverage consists of six rows.
The most recent data points are from 2026‑02‑10 20:00 UTC for NO₂, PM10 and PM2.5, indicating that those three pollutants have been updated within the last three days. In contrast, CO (2024‑09‑19 13:00 UTC), O₃ (2024‑09‑20 21:00 UTC) and SO₂ (2024‑08‑14 07:00 UTC) are older than a year, showing that the dataset mixes very fresh and considerably dated observations.
All six pollutants have a single recorded value, which also serves as their minimum, median and maximum. CO registers at 1 431.0 µg/m³, NO₂ at 17.1 µg/m³, O₃ at 50.9 µg/m³, PM10 at 27.0 µg/m³, PM2.5 at 24.0 µg/m³ and SO₂ at 5.5 µg/m³. Because each pollutant has only one measurement, there is no spread to describe; the data essentially provide a snapshot rather than a range.
Overall, the coverage is limited to one reading per pollutant, with half of the measurements being recent and the other half considerably older. This means that while the latest values for NO₂, PM10 and PM2.5 reflect current conditions, the CO, O₃ and SO₂ figures may not represent today’s air quality in Székesfehérvár, and variations across different parts of the city or over time are not captured by this dataset.
