What the data includes

The Sedloňov air‑quality feed draws from eight measurement rows supplied by two monitoring sites, each reporting the four key pollutants tracked on this page: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter ≤ 10 µm (PM₁₀). All values are expressed in micrograms per cubic metre. The most recent updates are fairly current for three of the pollutants, with NO₂, O₃ and PM₁₀ each refreshed on 2026‑02‑10 at 14:00 UTC, while the NO data point dates back to 2024‑03‑11 at 10:00 UTC, making it the oldest entry in the set.

Across the eight rows, the recorded concentrations show modest variability. NO values range from a low of 1.1 µg/m³ up to 1.4 µg/m³, with a median of 1.25 µg/m³; the spread is narrow, indicating relatively stable readings at the sites that report this gas. NO₂ exhibits a broader span, falling between 2.5 and 4.4 µg/m³, centred around a median of 3.45 µg/m³, which suggests more fluctuation in nitrogen dioxide levels across the two stations. Ozone measurements cover a wider interval from 47.9 to 81.6 µg/m³, with a median of 64.75 µg/m³, reflecting typical diurnal changes that are captured by the recent timestamps. PM₁₀ values are low overall, ranging from 3.2 to 6.8 µg/m³ and clustering near a median of 5.0 µg/m³.

Because only two stations contribute data, spatial coverage within Sedloňov is limited; conditions can differ in neighborhoods not directly represented by these rows. The freshness of most pollutants is good, but the older NO record highlights that some metrics may lag behind real‑time changes, so users should consider both the recency and the modest number of measurement points when interpreting the city’s air‑quality picture.

Data notes

The data shown for Sedloňov reflects three valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T14:00:00+00:00. This snapshot provides a current view of city‑wide air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
