What the data includes

The Kamenný Újezd dataset contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All of these come from a single monitoring station, so the city’s air‑quality picture is based on one row of data for each pollutant.

The timestamps show that most measurements are very recent, with NO₂, PM₁₀, PM₂.₅ and SO₂ all last updated on 2026‑02‑10 at 14:00 UTC, indicating fresh information within the past three days. The only older entry is for NO, recorded on 2024‑03‑11 at 10:00 UTC, which is flagged as “old data”. Consequently, five of the six pollutant readings are current, while one remains over a year old.

Across the pollutants the observed values are identical to their median and extreme points because each series contains only a single measurement. NO registers 0.5 µg/m³, NO₂ 5.2 µg/m³, PM₁₀ 8.5 µg/m³, PM₂.5 13.8 µg/m³ and SO₂ 1.3 µg/m³. With no variation in the data, there is no spread to describe; each pollutant’s minimum, median, maximum, 10th‑percentile and 90th‑percentile are the same figure.

Because the coverage relies on a single station, spatial differences within Kamenný Újezd cannot be captured. The dataset provides an up‑to‑date snapshot for most pollutants but offers limited insight into how conditions might change across neighborhoods or over longer periods. Users should keep in mind that the city’s air quality can vary by location and time beyond what this single‑point, mostly recent data reflects.

Data notes

The data shown for Kamenný Újezd is based on four valid measurements and was refreshed recently, having been updated within three days (last update: 2026‑02‑10T14:00:00+00:00). This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
