What the data includes

The Annaberg‑Buchholz air‑quality record contains six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All data come from a single monitoring station, giving six rows of observations in total.

The dataset is mixed in terms of freshness. The most recent updates for five pollutants (NO₂, O₃, PM₁₀, PM₂.₅ and SO₂) were recorded on 2026‑02‑10 at 17:00 UTC, indicating that the latest snapshot is only a few days old. In contrast, the NO value dates back to 2024‑03‑11 at 11:00 UTC, which is more than two years older and flagged as “old data”. Because each pollutant has just one reported figure, there is no range or variability shown – the minimum, median and maximum are identical for every substance.

The concentration numbers themselves are low and tightly clustered: NO sits at 3.942 µg/m³, NO₂ at 16.923 µg/m³, O₃ at 42.736 µg/m³, PM₁₀ at 12.311 µg/m³, PM₂.5 at 8.011 µg/m³ and SO₂ at 0.5 µg/m³. With only one monitoring location, the data reflect conditions at that specific site and may not capture spatial differences across the city. The presence of a single older NO measurement also means that recent trends for this gas cannot be assessed from the current record.
