What the data includes
The air‑quality record for Kroměříž in Central Moravia draws on a single monitoring station, so each pollutant is represented by one row of data. The dataset includes measurements for nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm and smaller (PM₁₀), fine particulate matter 2.5 µm and smaller (PM₂.₅), and sulfur dioxide (SO₂). For NO the most recent value dates back to 2024‑03‑11 10:00 UTC, while all other pollutants were last updated on 2026‑02‑10 14:00 UTC, which falls within the “updated within three days” freshness window. Because there is only one station, each pollutant’s reported minimum, median and maximum are identical, showing a single snapshot rather than a distribution over time or space.
The numbers themselves are tightly clustered: NO registers 0.5 µg/m³, NO₂ 7.7 µg/m³, O₃ 43.7 µg/m³, PM₁₀ 18.6 µg/m³, PM₂.₅ 3.4 µg/m³ and SO₂ 8.0 µg/m³. This uniformity reflects the limited temporal depth of the record rather than a lack of variability in the atmosphere; with only one recent reading per pollutant, any range or trend cannot be assessed from this dataset. The freshness profile is uneven: five of the six pollutants have very recent timestamps, but the NO measurement is over two years old, indicating that data for this gas are not being refreshed as regularly as the others.
Overall, the Kroměříž air‑quality snapshot provides a concise view of six key pollutants from one location, with most values updated within the last few days and only a single older entry. Because conditions can differ across neighborhoods and over time, the current figures represent a limited point in space and time rather than a comprehensive picture of citywide air quality.

Data notes
The data shown for Kroměříž are based on five valid measurements and were updated within three days, with the latest refresh recorded at 2026‑02‑10T14:00:00+00:00. This snapshot reflects conditions at the time of collection; air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
