What the data includes

The air‑quality dataset for Küssnacht (SZ) contains measurements from six individual rows, each representing a single observation at the Rigi‑Seebodenalp monitoring site. All six common pollutants are included: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µg (PM2.5) and sulphur dioxide (SO2). Every pollutant has exactly one recorded value, so the minimum, median and maximum are identical for each: CO is 151.7 µg/m³, NO2 2.9093 µg/m³, O3 72.9168 µg/m³, PM10 1.5974 µg/m³, PM2.5 1.3515 µg/m³ and SO2 0.289 µg/m³. Because each series consists of a single point, there is no statistical spread to report beyond that single figure.

All six rows were last updated on the same day, 2026‑02‑10 at 20:00 UTC, and are flagged as “Updated within 7 days.” This means the data are fresh for every pollutant, with no older or unknown timestamps in the current set. The uniformity of the timestamp indicates that the station reported all parameters simultaneously, rather than staggered or delayed submissions.

Because the dataset relies on a single monitoring location, it captures conditions only at Rigi‑Seebodenalp and does not reflect possible variations across other parts of Küssnacht. The lack of multiple stations means spatial coverage is limited, even though temporal freshness is good. Users should keep in mind that local micro‑climates or traffic patterns could produce different readings elsewhere in the city, which are not represented by this single‑site snapshot.

Data notes

The dataset for Küssnacht (SZ) contains six valid measurements and is updated within 3 days, with the latest values recorded on 2026‑02‑10 at 20:00 UTC. These figures represent a snapshot of ambient conditions; air quality can differ across neighbourhoods and change throughout the day, so local variations may not be captured by this summary.
