What the data includes
The dataset for Gorna Oryahovitsa includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulfur dioxide (SO₂). All values come from a single monitoring station, giving a total of five data rows. The most recent updates are fairly current for four of the pollutants: NO₂ at 23.35 µg/m³, O₃ at 32.78 µg/m³, PM₁₀ at 42.87 µg/m³ and SO₂ at 5.76 µg/m³ were all recorded on 2026‑02‑10 19:00 UTC, indicating that the system has refreshed these measurements within the last three days. The NO reading is older, captured on 2024‑03‑11 11:00 UTC, and is listed as “Old data,” showing a gap of almost two years for this particular metric.
Each pollutant’s reported statistics are identical across minimum, median and maximum values, meaning only a single measurement is available per parameter at the moment. For example, NO registers 5.52 µg/m³, while the other pollutants sit at their respective single‑point values noted above. Because there is just one station feeding all five rows, spatial coverage across the city is limited; variations in air quality that might occur in different neighborhoods are not captured by this dataset.
Overall, the data set offers a snapshot of current conditions for four pollutants but provides an outdated figure for NO. Users should keep in mind that with only one monitoring location and sparse temporal depth, the reported numbers represent a narrow view of Gorna Oryahovitsa’s air quality at specific moments rather than a comprehensive, city‑wide picture.
