What the data includes

The dataset for Sfântu Gheorghe contains measurements for four pollutants – ozone (O₃), carbon monoxide (CO), nitrogen dioxide (NO₂) and particulate matter ≤10 µm (PM10). These values come from six individual data rows that are grouped into two monitoring stations, so the spatial coverage is limited to a handful of points within the city. All readings were last updated on 2026‑02‑10 at 19:00 UTC, meaning the freshest information available is just over a week old and falls under the “updated within 7 days” category for every pollutant.

The recorded values show very little variation because each pollutant appears in only one row with a single measurement. Ozone reaches a maximum of 69.54395 µg/m³, while its minimum and median are identical at 40.54635 µg/m³, indicating that the available data capture a narrow slice of the city’s ozone range. Carbon monoxide is reported as a constant 50.88 µg/m³, nitrogen dioxide as 20.23403 µg/m³ and PM10 as 14.41954 µg/m³, each with no observed spread across the dataset.

Because the data set includes just two stations and six rows, it does not provide a broad temporal or spatial picture of air quality in Sfântu Gheorghe. The uniform timestamps and single‑value entries mean that conditions can differ elsewhere in the city or at other times, but such variations are not reflected here. Users should keep in mind that the current snapshot is limited to these specific locations and moments, and more extensive monitoring would be needed for a fuller understanding of local air quality dynamics.
