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 Općina Trnava air‑quality feed currently contains data for seven measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), particulate matter of 1 µm (PM₁), 2.5 µm (PM₂.₅), 10 µm (PM₁₀) and sulfur dioxide (SO₂). All values come from a single monitoring site, identified as Trnava‑1, so the dataset consists of one row per pollutant.
Each pollutant’s most recent observation was recorded on 2026‑02‑10 at 18:00 UTC, meaning the data are all updated within the last three days. The reported concentrations are identical for minimum, median and maximum values, indicating that only a single measurement is available for each parameter at this time. CO registers at 695.6 ppb, NO at 5.8 ppb, NO₂ at 0.1 ppb, PM₁ at 39.6 µg/m³, PM₂.₅ at 53.4 µg/m³, PM₁₀ at 58.1 µg/m³ and SO₂ at 0.2 ppb.
Because the dataset relies on a single station, spatial coverage across Općina Trnava is limited; conditions may differ in other parts of the municipality. The uniform timestamp shows that all pollutants share the same freshness, but the lack of multiple readings prevents any assessment of variability over time or between locations. Consequently, while the current snapshot provides up‑to‑date concentrations for each listed pollutant, it does not capture broader temporal trends or geographic differences within the city.
