What the data includes

The Chemnitz air‑quality dataset currently contains five measured pollutants – nitrogen dioxide (NO₂), ozone (O₃), nitric oxide (NO), particulate matter 10 µm or smaller (PM10) and particulate matter 2.5 µm or smaller (PM2.5). These values come from three monitoring stations that together provide nine individual rows of data.

For the most recent pollutants, the newest readings are all dated 2026‑02‑10, which means they were updated within the last three days. NO₂ at the Hans‑Link‑Straße site shows a minimum of 7.265 µg/m³, a median of 12.52 µg/m³ and a maximum of 33.462 µg/m³, with the central 80 % of values ranging from about 8.3 to 29.3 µg/m³. Ozone at the same location varies between 49.498 and 62.27 µg/m³, median 55.884 µg/m³, and its 10‑90 % spread is roughly 50.8–61.0 µg/m³. PM10 and PM2.5 each have a single recent measurement from the Leipziger Str. site – 34.839 µg/m³ for PM10 and 24.819 µg/m³ for PM2.5 – both recorded on 2026‑02‑10 at 17:00 UTC.

The NO data are older, with the latest value (18.773 µg/m³) recorded on 2024‑03‑11 at 11:00 UTC at Leipziger Str., and therefore do not reflect current conditions. Overall, three of the nine rows are classified as “old” and four have a freshness status of “updated within 3 days”, while no rows are marked unknown or very recent (within the last day). This mix means that for most pollutants the dataset offers a fairly fresh snapshot across two locations, but the nitrogen oxide measurements are dated and may not represent today’s air quality. Consequently, conditions can differ between sites and over time, so the available figures give only a partial view of the city’s current atmospheric state.

Data notes

The dataset for Chemnitz includes five valid measurements and is refreshed regularly, having been updated within the past three days (last update: 2026‑02‑10 18:00 UTC). These figures represent a snapshot of current conditions; air quality can differ across neighborhoods and change throughout the day, so values shown may not reflect conditions at every location or moment in the city.
